In many cases, the use of gate valves is required in pipelines. The use of such gate valves has a certain ability to regulate and control the flow of pipeline media. Especially when the flow rate of the medium in the pipeline is too much, the flow rate is too fast, this American standard gate valve can play a good interception effect in the pipeline, and the control effect on the medium is still very strong. As an American standard valve, this gate valve is similar to the national standard gate valve, and the function is the same. The main difference lies in their structure and some standard coefficients. This is the main way to distinguish them. As a device, its installation and maintenance are also designed. Here are some of its main installation precautions.
The correct approach is to properly lift the gate 1~3mm (mainly for high-pressure valves) after adjusting the closing position with the handwheel, so as to avoid excessive opening torque caused by abnormal pressure rise in the middle cavity. If the closing stroke of the flat gate valve is too large, the gate will often be cracked (or deformed). The closing stroke position can be adjusted during debugging, and no excessive closing torque is required.
