Requirements for installation direction of knife gate valve

? ? Knife type gate valveIt is a valve widely used in industries such as sewage treatment, papermaking, and chemical engineering, which plays a role in cutting off the flow of media. The safety direction of knife gate valves is something we need to pay attention to.

Requirements for installation direction of knife gate valve:

1. Valve body direction: The valve body of a knife type gate valve usually has an arrow indicating the direction of flow of the medium. During installation, ensure that the direction of the arrow is consistent with the flow direction of the medium.

2. Vertical installation: Knife gate valves are usually recommended to be installed vertically, with the valve stem facing upwards. This can prevent impurities from accumulating inside the valve body, ensuring the sealing and smooth operation of the valve.

3. Horizontal installation: In certain specific situations, knife gate valves can be installed horizontally, but it is necessary to ensure easy operation and consider the flow characteristics of the medium and possible accumulation of impurities.

When installing knife gate valves, the following points should be noted:

1. Avoid reverse installation: Do not install the knife gate valve in reverse, as it may affect the sealing effect and even cause valve damage.

2. Prevent impurities from entering: Before installation, ensure that the pipeline is clean to prevent impurities from entering the valve body and affecting the normal operation of the valve.

3. Special working condition considerations: In some special working conditions, such as high temperature, high pressure, or corrosive media, suitable blade gate valve materials should be selected and installation recommendations provided by the manufacturer should be followed.
