Application of the Gas Burner Safety Valve

Gas Burner Safety Valve is a device for supporting the safety of new gas pipeline projects. It used to cut, turn, regulate the gas pipeline, has good control properties and close the sealing performance. 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 the form of a manual, worm gear, electric, pneumatic, hydraulic, electro-hydraulic actuator linkage, enabling remote control and automation. For a variety of city gas medium pipeline gas, liquefied petroleum, natural gas and oxygen.

QUS Range Top Burner Valve size and type

Range Top Burner Valve size and type, shall meet the requirements of piping design documents.
1, the gas top burner valve type should be specified in accordance with national standard code requirements. If the enterprise standards, should be specified instructions model.
2, valve job pressure ≥ pipeline working pressure, without affecting the price of the premise, the valve can withstand working pressure should be greater than the actual pipeline working pressure.
3, the burner valve manufacturing standards, should explain the basis of the national standard code, if the file should be attached to business enterprise standards, procurement contract.

The valves are the main components fraud stove

The valves are the main components fraud stove, desk-top stove, for example, taps and gas safety burner valve by the body two parts, the cock cone has two sets of vent holes Group 1 air vent is supplied to the igniter, and the second Group vent is supplied to the burner gas supply. Two vent valve respectively leading to the ignition device and the burner gas supply line. When the knob is pressed in the end, the cock is rotated 90 degrees to the left, then the first group and the gas burner valves leading to the ignition vent port means of communication, to the ignition gas, the second group of the main vent and vent valve to the burner the pores communicates gas, an ignition device action ignition, to ignite the burner, the maximum amount of gas in the state at this time, the heat maximum flame. After the release knob, ignition pores in the spring and the valve tap is turned off, the ignition end. When the knob is rotated to the left continues to gradually close the tap main pores small flame gradually reduced to 90 degrees with the main gas valve to the burner pores open, the second set of vent holes in the valve body to the combustion fire the pore connectivity, because of the small amount of gas fire hole flame decrease in fire protection status. Bicyclic fire with dual burner stove with double air valve allows the state at the time of the fire protection, leading to the gas control valve closed, only the inner fire breather, saving gas, convenient to use.

Gas burners safety valve of understanding

Gas coming from the direction of the first one is the safety valve, the second is operated valve, double solenoid valve is set to double insurance, in case of a solenoid valve leak, and there is gas burner valves to ensure that does not leak. To ensure this, there are no two solenoid valves are bad, the actual operation between the two solenoid valve is also equipped with leak detector, if there is a leak valve, the burner valves can not open the solenoid valve, and thus not start burner, repair or replace the solenoid valve must ensure two solenoid valves do not leak before starting the burner. However, gas pressure switch (high and low voltage protection) is not the valve is a pressure sensing switch, if the gas pressure is low, low voltage protection switch because of low pressure, a mechanical spring or similar mechanism would disconnect switch, this switch is a string programmed in burner main power circuit, after low pressure protection switch off the burner does not start.

Safety valve - Development

Safety valve, the valve of a special branch of the family, it's particularity is due to a safety valve that is different from other valves only acts as a switch, more importantly protect the safety of the device. With the rapid development of China's economic construction, the project works with a pressure control equipment is increasing. Given the need for pressure relief devices, safety plays a crucial role in the protection device process. Boiler safety valve is an important safety accessories pressure vessels and other equipment under pressure. Gas Valves For Patio Heater (also known as pressure relief valve) is automatically open and close depending on the pressure system operating pressure (temperature), usually installed in equipment pipeline protection system security or closed system. When the equipment or pipeline pressure or temperature exceeds a set pressure relief valve, pressure relief or cooling automatically open to ensure that equipment and the pipeline medium pressure (temperature) is below the set pressure (temperature), protective equipment and piping work, prevent accidents and reduce losses. The main Bbq Gas Valve is widely used in: steam boilers, LPG tankers or liquefied petroleum gas rail tankers, oil wells, high pressure bypass steam generating equipment, pressure piping, pressure vessels. Valve general form of the structure is divided into spring safety valve and lever safety valve, pulse valve, where the most common spring safety valve; press connection into threaded flange valve and safety valve. Valve diameter are generally not large, the most common are between DN15mm-DN80mm than 150mm generally called large-diameter Parts Oven Safety Valve. 2013 valve industry market scale, this is an indisputable fact. Our all-copper sealing valve can have the number of qualified production safety valve business is not much, because the safety valve is part of the special equipment industry, the State Administration of Quality Supervision review of the application of more stringent qualification, and great safety valve market demand, no doubt to The qualified production safety valve business has brought more wealth opportunities.
