How does a threaded check valve work?
Threaded check valve refers to a valve that automatically opens and closes the valve flap according to the flow of the medium itself to prevent the backflow of the medium.
Working principle and failure analysis of pneumatic valve
The so-called pneumatic valve specifically refers to the use of the cylinder as the actuator and the compressed air as the power source to drive the valve to adjust the switch. When the regulating pipeline receives the control signal sent by the automatic control system
Advantages and disadvantages of pneumatic valves and electric valves
The action torque of the pneumatic valve is larger than that of the electric valve. The switching speed of the pneumatic valve is adjustable. Simple structure and easy maintenance. Due to the cushioning characteristics of the gas itself, it is not easy to be damaged due to jamming during the action. It has an air source, and its control system is also more complicated than an electric valve.
What are the advantages of a control valve?
In terms of operating efficiency and saving energy consumption, the use of automatic control valves is an indispensable part. Manual valves and pneumatic valves commonly used in traditional industries are inferior to electric valves in terms of installation cost and efficiency.
Advantages of electric valves over traditional valves
If there is a slight leak at the packing, retighten the stem nut. But don't lock it too tightly, generally lock 1/4 turn to 1 turn, it will not leak.
Briefly describe the classification and structure of ball valves
Ball valves are divided into: floating ball valve, fixed ball valve, orbital ball valve, V-shaped ball valve, three-way ball valve, stainless steel ball valve, cast steel ball valve, forged steel ball valve, ash discharge ball valve, anti-sulfur ball valve, pneumatic ball valve, electric ball valve, ferrule ball valve, Welded ball valve.
Specific price support policies for clean heating introduced
According to the policy, for areas suitable for "coal-to-electricity", a residential electricity price will be implemented for the reasonable heating power of residents determined by each province.
