American standard stop valve can be divided into straight type, three type and right angle type according to its channel position. The latter two types of gate valves are used to distribute the medium and change the direction of the medium. Attention should be paid to the installation and maintenance of stop valves in power stations:
1. Keep the position where the valve handle rotates.
2. Cannot be used as throttling.
3. Ball valve with transmission mechanism should be installed upright.
The sealing surface of the stop valve of the power station is not easy to wear and abrasion, and has good sealing performance. There is no relative sliding between the valve disc and the valve body sealing surface during opening and closing, so the wear and abrasion are not serious, the sealing performance is good, and the service life is long. When opening and closing, the valve flap has a small stroke, so the height of the stop valve is smaller than that of the gate valve, but the structure length is longer than that of the gate valve.
