Gas valve use

Gas valves are widely used for a variety of city gas pipeline network system media pipeline gas, liquefied petroleum gas, natural gas and oxygen. Drive in the form of a manual, worm gear, electric, pneumatic, hydraulic, electro-hydraulic actuator linkage, enabling remote control and automation.
Valve - used to automatically reduce the pipeline and the gas pressure inside the equipment. Department of the gas passes through the gap between the Gas Burner Safety Valve, resulting in resistance caused by pressure loss, to achieve the purpose of decompression.
According to use, depending on the purpose of the valve can be divided into:
1. Breaking use: Used to connect or disconnect the gas pipeline, such as the cut-off valve, gate valve, ball valve, butterfly valve.
2. backstop use: to prevent backflow of gas, such as check valves.
3. Adjust with: used to adjust the gas pressure and flow regulating valve, pressure reducing valve.
The assignment: to change the flow of the gas, gas distribution, such as the three cocks, dispensing valve, the slide valve.
Press the drive, depending on the driving mode can be divided into:
1. Manual: With hand wheels, handles, levers or sprockets, etc., there are human-driven, when the drive is larger torque reduction device equipped with worm gear.
2. Electric: With the motor or other electrical device to drive.
3. pneumatic; with compressed air to drive.
Press and pipeline connection points, according to the valves and pipe connections can be divided;
1. flanged valves: valve with flanges, valves and pipes are flanged.
2. The threaded connection valves: a valve body with an internal thread or external thread, and the pipe valve with a threaded connection.
3. welded connection Range Top Burner Valve: Body with weld, and pipeline valve with solder connections.
4. clamp connection valve: the valve body with the jaws, and pipeline valve with clamp connections.
5. ferrule connection valve: A valve sleeve and the pipe connections.

The classification of gas valve

Gas valve is a safety device supporting a new gas pipeline project. Used to cut, turn, adjust the gas pipeline, with good control characteristics and closing the sealing performance. For a variety of city gas medium pipeline gas, liquefied petroleum gas, natural gas, oxygen and so on. Gas valve widely used, a wide range of classification methods more. The total can be divided into two categories:
The first automatic valve: the ability to rely on the gas itself and self-acting valve. Such as check valves, control valves, pressure reducing valves and so on.
The second class driver valve: With manual, electric, pneumatic valves to manipulate the action. Such as gate valves, globe valves, throttle valves, butterfly valves, ball valves, plug valves, etc.
In addition, the valve's classification as well as the following methods:
By structural features, according to the closure member to move relative to the direction of the seat can be divided into:
1. Door-shaped cross-section: off pieces move along the seat center.
2. Gate shape: off pieces move along the vertical seat center.
3. cock and ball: closure member is a plunger or ball, rotating around the center line itself.
4. Swing shape: off pieces around the outside of the seat axis.
5. dish: the closure member disc around the axis of rotation of the Gas Top Burner Valve seat.
6. spool-shaped: the closure member in a direction perpendicular to the sliding channel.
Category according to the structure are:
Plug valves, gate valves, globe valves, ball valves - used to open or close the gas flow pipe. Check valve (including bottom valve) - used to automatically prevent backflow of gas pipeline.
Throttle - for regulating the flow of gas pipelines.

The advantage of the new safety valve

Recently, the reporter came to the Dagang Oilfield Company Oil Production Oil Factory, six teams board twenty-five station. I saw in a room measuring 5 meters splitter top, a female employee will bite valve alignment interface wrist thick, airy hoop screwed into the high pressure section, check and correct, slid down the ladder metering room, but after 10 minutes.
This time of year, oil board twenty-five six teams have focused on completing the loading and unloading stations, testing the safety Burner Valve of the physical work. This year, the station staff no longer have the safety valve of handling and distress, because through technological innovation, they were using a new type of safety valve.
"In the past, high-pressure gas-separation is a safety valve, diameter 100 mm, enough to have 60 kg weight, handling, together with the four boys, but also with one hour. We now use this safety valve, only 1 kg heavy. "a worker said.It is understood that since the Dagang Oilfield Company, created to carry out the "four small" team activities, the team combined with actual production, the establishment of the "innovative" small team, organization employees around the management weaknesses conduct research. The team leader, told reporters in the past the team to engage in technological innovation, and production technicians are the backbone of the thing, team staff involved are not enthusiastic. After striving for "innovative" small team activities, we are mobilizing the enthusiasm and love to think more employees. Technological innovation has become the highlight of the team excel.Activities, maintenance classes for board twenty-five station splitter valve bulky, time-consuming and laborious annual check handling problems, the splitter Gas Burner Safety Valve interface reconstruction projects as innovative research. Metering separators are high-voltage equipment, in order to ensure safety, they repeatedly ask the pressure vessel and technical experts, to understand the security of oil and gas separator pressure range master valve
works and use specifications. After much research, maintenance classes subtly changed the installation caliber, to ensure the flow of qualified during take-off, based on the successful novel valve "grafted" onto the splitter, thereby greatly reducing the intensity of the work to achieve a single easy loading and unloading safety valve of technical innovation in mind.

Prospects of valve industry

   In recent years, China's valve industry has entered a rapid development period, the valve industry threshold gone now become Asia's largest valve machining center, one of the largest valve market. However, China's per capital consumption level valve products in the world is not high, currently only $ 22 per capital. But with the rise of the power Water Heater Gas Valve, chemical valves, valves, valves, and other building materials and food, we can see that the valve industry prospects, the market is attractive.
   By 2015, China's valve market than the US market is large 10%, four times larger than Japan's market. Buyers who will buy $ 2.4 billion worth of valves. By 2015, buyers of the top ten rankings of the three, as well as ranking in the top twenty six will have in Asia. China's valve industry should increase investments in technology, upgrade the industry, to carry out all aspects of school-enterprise cooperation in the dynamic balance of the patio heater control valve

 to open up international markets, brand image, and so do a lot of work.
  And this year the equipment manufacturing industry has been an important pillar industry of China's economic development, fluid machinery has a pivotal role in the state's major machinery and equipment, and undertakes to provide complete sets for the petrochemical, power, metallurgy, environmental protection, water conservancy, municipal and other industries arduous task of supporting and key technologies, many sets of major technical equipment in the core equipment.  
  Valve industry should form enterprise groups, investments in technology, development of high, high precision and advanced valve products; enhancing product standardization work, so standards need to keep up with the number and level of development of the situation.

How to regulating valves properly

  Gas Heater Control Valve is installed in the gas cylinder angle gas patio heater valve angle valve with hose connection,serve to reduce the output pressure and stable output pressure of household gas appliances supporting important gas equipment, has a simple structure, the pressure is stable, lightweight,adjustable mounting and easy. Mainly by the inlet, outlet, the hand wheel, the Safety Valve cover, a lower Gas cooking valve cap, air intake mouth, breathing holes, the gas chamber, pressure chamber, the valve pads, levers, rubber membrane, a spring, regulating plug and other components.
  Residential customers gas leak accidents have occurred, a serious threat to people's lives and property. However,when we exclude the lack of user awareness of gas with the relevant knowledge, the analysis of the truth of the accident, we also found that an important reason for this is the proper use of a pressure reducing relief valve has yet to pay close attention. According to statistics, 80% of the Gas Cooker valve of the accident was due to their quality and user caused by improper use.
  Regulator steps are as follows:
  1. Close gate valve before the open gate Barbecue Valves after manufacture downstream low pressure environment;2.the adjusting screw Natural Gas Safety ValveCounterclockwise rotation to the uppermost position (relative to the minimum outlet pressure), and then close the Safety Valve after the valve;3. Slowly open the gate valve to fully open the front;4.Slowly turn adjustment screw clockwise, the pressure is adjusted to the required outlet pressure (gauge pressure in the valve prevail); adjusted, the lock Nut, open the pilot valves;5. The outlet pressure is higher than the set pressure adjustment shall begin from the first step to re-adjust, that can only be adjusted from low to high pressure.
  With the extensive application of

gas safety valves, please correct installation, maintenance, processing the gas stove valve and other critical issues, I hope this can guide users to increase safety awareness, purchase qualified high quality gas valve, the gas from the source to prevent accidents occurs.
