Hose connector to pay attention to

Said pants specializing in the production of hoses, fittings, high pressure hose, often some of the problems of the customers in the use of accessories to meet the pants here, we tell you pants accessories should pay attention to three questions:high pressure hydraulic fittings
His pants accessories carefully open the package, do not let the tube interrupt, in order to avoid tangled, and then cut when the wire is less or more, need to wear a harness or cable length, try to use the hard disk trousers connector, so when relatively simple wear harness over the water or other liquids, cut tubes filled with water to try to see does not leak, so do not split.
Is a large mechanical or automotive wiring harness, it is recommended and pants to cut the use of open longer to save more due to the large machine harness is not likely to occur: such as the use and cut directly to the comparative work When the lines in the most secure with tape.
If water is waterproof and can be accompanied by a high-pressure hose connection, if you have to use the national standard plug in the open, such as high-pressure hose should be used and the standard model, but also when the pipe and plug-ins inaccurate or pipe do not go to most of the cards, and so on. Tube should we go slightly harder, this card is a plug-in, fall on the train.metric hydraulic hose fittings

Ways to avoid flashback

Ways to avoid flashback：
The sudden closure of the stove top burner valve, with the flame goes out will backfire noise, coke oven gas than natural gas and liquefied petroleum gas are more prone to temper noise. Tune wind deflector open through the large, so the primary air coefficient is too large, easily lead to tempering, by adjusting the adjustable air board can be ruled out. Gas supply pipes, gas burner valve, burner nozzles, fire sub L Levin blocked rice dregs, carbon black or other substances, insufficient gas pressure in the gas cylinder, the gas will reduce the flow rate, resulting in tempering, can by cleaning the dirt, inflatable avoided.

Solution Turn off the heat for a long time can not be closed gas

Solution Turn off the heat for a long time can not be closed gas burner valve：
Flameout protection device in the transmission mechanism is not working properly blocked and will not be shut gas burning appliances should first turn off the gas stove valves, actuator and check the adjustment means if there is an obstacle, if any, to be cleared.
