In order to flexibly handle the use of machinery and equipment in the process of using many machinery and equipment or pipelines, a valve is usually installed on the equipment. Of course, different valves play different roles. What should we pay attention to when installing the electric control valve? For this problem, a detailed analysis will be carried out so that everyone can understand it clearly. 　　　　

Therefore, unlike the existing technology, the utility model is not installed on the valve plate with soft and hard multi-layer sealing rings, but directly installed on the valve body. Adding an adjusting ring between the pressing plate and the valve seat is a very ideal two-way hard sealing mode. It can replace gate valve, globe valve and ball valve. Butterfly valve is suitable for flow regulation. Since the pressure loss of butterfly valve in the pipeline is relatively large, about three times that of gate valve, when selecting butterfly valve, the impact of pressure loss on the pipeline system should be fully considered, and the solidity of butterfly plate to withstand pipeline medium pressure when closing should also be considered. In addition, consideration must be given to the limits of the operating temperature of the resilient seat material at high temperatures.
