Root valve of gas-liquid linkage valve
Thread Content
What are the material and diameter requirements for the root valve of a gas-liquid linkage valve? We have been supplying Shafer gas-liquid linkage actuators before, and recently we will provide root valves at the request of most users. We have also provided imported root valves before, but the price was too high and the delivery time was not timely. In the near future, we will launch a root valve with a diameter of 1/2" and a valve core made of stainless steel and a valve body made of forged steel with prompt delivery. Where is the root valve used?
After the gas-liquid linkage actuator on the natural gas line is installed on the valve of the pipeline, there will be three pressure pipes leading from the upstream and downstream of the valve. Two of them are power gas pressure pipes for the gas-liquid linkage actuator. They are installed upstream and downstream of the valve, at least 1 times the valve diameter from the center line of the valve. ； The other is a pressure drop rate detection (sensing) pipe, which is generally installed downstream of the valve at least 2 times the valve diameter from the valve centerline. The valve installed on the pressure pipe closest to the main pipe is the root valve. According to the actual situation of the project pipeline, the root valve can be installed in two ways: exposed and buried. The root valve is the first door through which the pipeline gas exits.

The root valve is the first door for pipeline gas to the actuator. The end connection method of the root valve is usually flange type or welding type. For buried root valves, if the end adopts flange connection method, there will be slight improper installation and operation process, coupled with the acid and alkali corrosion of the flange by the soil, the service life will be shortened. * * It also poses a great hidden danger to the safety of the main line, not to mention the waste of energy resources and the threat to the lives and property of people living and working near the pipeline. Therefore, in recent years, the end connection method using welding has been deeply promoted and used in major projects.
