Gate valve refers to a valve whose closing part (gate) moves along the vertical direction of the channel axis. It is mainly used for cutting off the medium in the pipeline
The working principle and failure analysis of pneumatic valveTime of issue : 2021- 12-22
The so-called pneumatic valve specifically refers to the use of a cylinder as an actuator and compressed air as a power source to drive the valve to adjust the switch.
How to choose electric ball valve correctlyTime of issue : 2021- 12-22
According to reports, in the next 10 years, my country will have more than 20,000 kilometers of oil pipelines to be constructed, including transnational oil pipelines such as Russia and Kazakhstan. In addition, following the "West-East Gas Pipeline", my country has to build more than 20,000 kilometers of transnational gas pipelines and branch lines.
How to choose a high-quality electric ball valveTime of issue : 2021- 12-22
The practice of only specifying specifications, categories, and pressures to meet the procurement requirements when purchasing electric ball valves is imperfect in the current market economy environment. For the sake of product competition
Advantages and disadvantages of pneumatic valves and electric valvesTime of issue : 2021- 12-22
Pneumatic valve has a larger action moment than electric valve. The switch action speed of pneumatic valve can be adjusted. The structure is simple and easy to maintain. Due to the cushioning characteristics of the gas itself, it is not easy to be damaged due to jamming during the action. It has a gas source and its control system is also More complicated than electric valves.
The advantages of electric valves over traditional valvesTime of issue : 2021- 12-22
In terms of operating efficiency and saving energy consumption, the use of automatic control valves is an indispensable part. The manual valves and pneumatic valves commonly used in traditional industries are not as good as electric valves in terms of installation cost and efficiency.
Precautions for ball valve maintenanceTime of issue : 2021- 12-22
If there is a slight leakage at the packing, the stem nut must be tightened again. But don't lock it too tightly, usually lock 1/4 turn to 1 turn, the leakage will stop.
