How to adjust Xianfeng gas valve

Generally, the factory directly adjusts. This cannot be adjusted. This valve is safer. The price is also high and the quality is relatively better. Adjustable, the pressure gauge is a reversible valve, which can be adjusted directly from left to right.

Gas valve is a new type of safety support device for gas pipeline engineering. Used to cut off, connect and adjust the gas in the pipeline, with good control characteristics and sealing performance. Suitable for city gas, liquefied petroleum gas, natural gas, oxygen and other gas medium pipelines.

Air valves have a wide range of uses, types and classification methods. Generally can be divided into two categories:

The first type of automatic valve: a valve that acts by itself depending on the ability of gas itself.

The second drive valve: a valve operated by manual, electric and pneumatic means. Such as gate valves, globe valves, throttle valves, butterfly valves, ball valves, plug valves, etc.

In addition, there are several valve classification methods:

According to the structural characteristics, according to the movement direction of the closing piece relative to the valve seat, it can be divided into:

1, truncated door shape: the closing piece moves along the center of the valve seat.

2. Gate shape: The closing member moves along the center of the vertical valve seat.

3. Cock and ball: the closing part is a plunger or ball, which rotates around its own center line.

4. Swing shape: the closing part rotates around the shaft outside the valve seat.

5. Dish-shaped: the disc of the closing part rotates around the axis in the valve seat.

6. Slide valve shape: the closing piece slides in the direction perpendicular to the channel.

According to the structure type, mainly include:

Plug valve, gate valve, globe valve, ball valve-used to open or close the air flow in the pipeline. Check valve (including bottom valve)-used to automatically prevent gas from flowing back in the pipeline.

Throttle valve-used to adjust the flow of pipeline gas.

Pressure reducing valve-used to automatically reduce the gas pressure in pipelines and equipment. When the gas passes through the gap between valve discs, it produces resistance and causes pressure loss, thus achieving the purpose of pressure reduction.
