Hard seal gate valve features and operating environment, as well as procurement precautions, and maintenance of the detailed introduction

Hard seal gate valve is a valve with wear resistance, corrosion resistance, high temperature resistance, low temperature resistance, good sealing and so on. Its main characteristics are as follows:

1. Good sealing performance, small opening and closing torque.

2. With fire, explosion-proof, anti-static and other safety performance.

3. Long service life, simple maintenance.

4. Wide application range, can be used for high pressure, high temperature, low temperature and various industrial media.

5. Excellent flow characteristics and good adjustment performance.

Hard seal gate valve is suitable for petroleum, chemical, metallurgy, electric power and other industries. When using a hard seal gate valve, the following points should be noted:

1. Select the correct specification and material, and select according to the medium characteristics and use environment to ensure the valve performance.

2. The operation shall be carried out according to the valve installation and operation instruction.

3. Keep the valve clean and dry during use to avoid corrosion and scratches on the surface.

4. The storage and handling of the valve should pay attention to avoid collision and serious vibration.

In terms of maintenance, the hard seal gate valve has a long life and is relatively simple to maintain, but it needs regular inspection, maintenance and maintenance.

1. Check the sealing performance of the gate valve surface. If there is water leakage, replace the sealing ring or other sealing parts in time.

2. Regularly clean the impurities inside the gate valve, such as dust, sand, etc., to ensure the smooth flow.

3. In the process of use, attention should be paid to whether the motion of the gate valve is smooth, if not smooth, you can apply a small amount of lubricating oil.

4. During the normal use of the gate valve, it should be checked and fastened regularly to ensure the safe and reliable operation of the gate valve.

In short, hard seal gate valves have been widely used in various industrial occasions. Choose according to the actual needs, maintenance should pay attention to the use and cleaning of the valve, as well as regular inspection and maintenance.
