Gas valve has good control properties

Gas valve is a device for supporting the safety of new gas pipeline projects; use truncation is turned on, adjust the gas pipeline, has good control properties and close the sealing performance; suitable for city gas, liquefied petroleum gas, natural gas, oxygen gas pipeline and other media. Gas table top with a red material button, it is automatic emergency shutdown burner valves, if gas consumption exceeds a certain value, it assumes that leak automatically closed, open it is very simple, open and transparent plastic cover above the button, grab the red button Gently pull up just fine.

The basic operating principle cooker

The basic operating principle cooker
The basic operating principle can be divided into the ignition phase, a mixed fuel, ignition phase, the combustion stage. Ignition phase: ignition pressure to open the gas valve, the gas through the pipeline with some pressure coming from the nozzle; a co-firing: Since the kinetic energy of the gas ejector effect, the nozzle of the gas sucked from the primary air damper, in the ejector completed within a mixed gas ignited stages: the mixture flowing through the fire free standing gas stoves, hit the fire source ignition occurs, start ignition; combustion process: after ignition of gas obtained from the secondary air supply around the stove, complete complete combustion.

As a gas core parts - valves

Our company to a solid strength, advanced technology, professional manufacturing open market, "valve", as a gas core parts - gas Burner Valves, we produce a lot of gas valves become a manufacturer of choice. We are one of the manufacturers involved in the earlier gas valve assembly production, with all kinds of advanced automated production line and precise product inspection side of the instrument, the indicators are better than national standards.
In the "excellence, social services," business philosophy, to win with quality, professional known for the production of technical difficulties to break through the valve to open the market, "valve." The national response to the call of the western development strategy, with the relevant departments to promote rural Forest in Western China, the implementation of biogas projects. Developed a patented product has two ignition and protection of one gas stove valves and gas lamps ancillary products, and achieved gratifying results and economic benefits.

Don't forget the closed end gas valves

Don't forget the closed end gas valves
Attention to small details of life to develop good habits, to master the correct way to turn off the gas cookers after use should be shut off the gas valve on the pipeline or on the gas cylinders, and so on and then off the fire extinguishing gas stove switch, to ensure safety. In addition, before going to sleep, when they go out further checks whether the gas should have been closed. Recommends that users regularly check whether the hose aging, loose connections and other security risks, it is recommended to turn off the main gas valve safer, there are no long-term or taking a trip when you want to turn off the main valve to prevent leakage.

Dynamic stability of the safety valve

When the protected system pressure increases, resulting in an additional force elements acting on feelings, so that the element moves to open a gap in the valve passage, the medium is discharged through the gap.
Its part of the life of the discharge capacity of the safety valve, safety valve and dynamic stability in work on. Channel cross-sectional area and the discharge capacity of the Gas Heater Control Valve of the shock would reduce the safety valve, and the valve seat and the same opening height limit collision bits will damage the valve sealing surfaces and other parts. two acting safety valve most likely to produce valve shocks.
Dynamic safety valve instability is mainly caused by the following reasons: Pilot operated safety valve discharge capacity is more than a safety valve into the media flow, spring just had big, big back pressure valve and the outside world in the chamber when the valve is opened Dynamic interference.

Classification of the safety valve

Valve structure are two major categories: spring-loaded and leveraged. Spring means sealing valve and valve seat by spring force. Leveraged rely on leverage and weight forces. With the large capacity needs, harboring a pulse valve, also known as the patio heater control valve, the main valve and the auxiliary valve. When the pipeline medium pressure exceeds a predetermined pressure value, the auxiliary valve to open, the media along the catheter into the main gas stove safety valve and the main valve is opened to reduce the media pressure increased. Emissions safety valve depends on the caliber of the valve seat and valve opening height, it can be divided into two types: Weiqi opening height is the seat diameter (1/20) - (1/40), the entire Kai It is (1/3) - (1/4).
In addition, with different requirements, there are enclosed and non-enclosed. Enclosed discharge medium that is not compromised, the entire exhaust outlet along a predetermined, generally used for toxic and corrosive media. Enclosed is generally not used for toxic or corrosive media.

In the form of structural safety valve lever hammer

Simple lever hammer safety valve structure, adjust easily and more accurately, the applied load will not increase the valve flap and a larger increase for higher temperature of the occasion, it was more commonly used in the past, especially It is used in high temperature boiler and pressure vessel. But hammer lever Water Heater Gas Valves structure is relatively bulky, easy loading mechanism vibration, and often due to vibration leakage; lower its back seat pressure, not easy to close after opening and holding tight.
