Installation diagram of plug-in valve (analysis of correct installation steps for plug-in valve)

slide gate valveIt is a flow control device widely used in powder conveying pipelines. Proper installation is crucial to ensure the service life and control performance of the plug-in valve. Below are the specific installation steps for the plug-in valve:

1、 Check for cleanliness. Before installation, it is necessary to carefully inspect the inside of the valve body to ensure that there are no impurities such as dirt or sand adhering to the contact surface between the valve body cavity, gate plate, and sealing surface, so as not to affect the airtightness. If there is any dirt, it must be removed by cutting the bottom.

2、 Tighten the connection. The inlet and outlet flange bolts of the plug-in valve must be tightened in place and the torque must be controlled to ensure that the tightening degree of each bolt is uniform and consistent, preventing loosening and leakage at the connection.

3、 Fill and seal. The packing type plug valve should fully compact the packing to completely fill the sealing groove, ensuring the airtightness of the packing and allowing the gate to move freely without being too tight and affecting opening and closing.

4、 Verify consistency. It is necessary to carefully check whether the model, interface size, and flange connection standard of the plug-in valve are consistent with the actual pipeline parameter requirements. The flow direction of the fluid medium should also be consistent.

5、 Leave space. It is necessary to evaluate the operating space required for the drive device and reserve sufficient space during installation to achieve later operation and maintenance.

6、 Connect the wires correctly. The wiring of electric, pneumatic, and hydraulic drive devices must be strictly in accordance with the design drawings to ensure normal power transmission and control.

7、 Regular maintenance. After installation, regular maintenance must be carried out to avoid external collision and compression, so as not to affect the sealing performance of the valve.

Only by strictly following the above steps for the installation of the plug-in valve can it ensure its excellent flow control performance and achieve precise management of the powder pipeline.
