Bo Weiheng Valve Co., Ltd., April 29th News: Gas can generally be divided into blast furnace gas, coke oven gas, and gas generator gas according to its manufacturing equipment and manufacturing principles. Although they arise in different ways, they share common characteristics. Its characteristics are:

The pressure is not high. Usually 10-20kpa. After being pressurized by the gas station, it is generally below 100kpa.

The temperature is too high. Usually between 150-300 ℃. There are many impurities. Blast furnace gas contains more dust, coke oven gas contains more tar, and the gas produced by gas generators contains more dust and coal tar.

2、 Due to the above characteristics of gas, valves used in gas transmission pipelines are prone to many problems. There are several common ones, including the following.

1. The valve cannot be closed or opened.

2. The valve switch is not flexible.

3. The valve seal is not tight.

The main reason is that impurities in the gas adhere and bond to the valve sealing surface and valve shaft sleeve. So it reflects the importance of gas butterfly valves.

The automatic sewage line sealing gas special butterfly valve is driven by a driving device to drive the valve shaft, which drives the butterfly plate to rotate, achieving the purpose of opening and closing the valve. Due to the special design of the valve body, this series of gas specific butterfly valves ensures easy disassembly and maintenance of the valve. The design of the thermal discharge tank ensures timely removal of dirt and impurities, and the valve opens and closes flexibly. When the series of gas butterfly valves are opened, the design of the spherical sealing surface allows the butterfly plate to detach from the sealing seat in a very short time, thereby reducing friction. When closed, the butterfly plate and valve body seal seat form a line seal and a unique dirt removal design, ensuring 100% sealing. The gas specific butterfly valve with a sealed drainage groove can be connected to manual, electric, and pneumatic drive devices for remote control.
