Electric flange ball valve manufacturer

Electric flange ball valve manufacturers have a wide range of applications, with diameters ranging from a few millimeters to several meters, and can be used from high vacuum to high pressure. When fully open or fully closed, the sealing surfaces of the ball and valve seat are isolated from the medium, and when the medium passes through, it will not cause erosion of the valve sealing surface.

1. There are locking holes in the fully open and fully closed positions of the valve to prevent accidental operation by non personnel.

2. Set a step at the lower part of the valve stem to prevent abnormal pressure rise inside the valve from dislodging the valve stem.

3. A fire-resistant sealing ring is installed between the sphere and the valve seat, which still has a sealing effect even after the valve seat is burned.

4. Quick switch, flexible opening and closing, long service life, safe and reliable.

5. Pneumatic and electric ball valves can be remotely and centrally controlled, and can meet the needs of computer program control.

Advantages:

1. The fluid resistance is small, and its resistance coefficient is equal to that of a pipe segment of the same length.

2. Simple structure, small size, and light weight.

3. Tight and reliable, the sealing surface material of ball valves is widely made of plastic, with good sealing performance, and has also been widely used in vacuum systems.

4. Easy to operate, quick opening and closing, only need to rotate 90 ° from fully open to fully closed, making it convenient for remote control.

5. Easy maintenance, simple ball valve structure, and generally movable sealing rings make disassembly and replacement relatively convenient.

When fully open or fully closed, the sealing surfaces of the ball and valve seat are isolated from the medium, and when the medium passes through, it will not cause erosion of the valve sealing surface.

7. It has a wide range of applications, with diameters ranging from a few millimeters to several meters, and can be used from high vacuum to high pressure.

Repair method for electric flange ball valve manufacturer:

Only by removing the pressure before and after the ball valve can the ball valve be disassembled and disassembled.

2. During the disassembly and reassembly process of ball valves, it is necessary to protect sealed components, especially non-metallic components such as O-rings, using specialized tools.

3. When reassembling the ball valve body, the bolts must be tightened symmetrically, gradually, and evenly.

4. The cleaning agent should be compatible with the rubber parts, plastic parts, metal parts, and working media (such as gas) in the ball valve. When the working medium is gas, gasoline (GB484-89) can be used to clean metal parts. Non metallic parts should be cleaned with purified water or alcohol.

5. The decomposed individual parts can be cleaned by immersion washing. Metal parts that have not yet decomposed can be cleaned with a clean and fine silk cloth soaked in cleaning agent (to prevent fibers from falling off and adhering to the parts). During cleaning, all grease, dirt, adhesive buildup, dust, and other substances adhering to the wall surface must be removed.

6. Non metallic parts should be immediately removed from the cleaning agent after cleaning and should not be soaked for a long time.

7. After cleaning, it is necessary to wait for the wall cleaning agent to evaporate (which can be wiped with a silk cloth that has not been soaked in cleaning agent) before assembly, but it should not be left for a long time, otherwise it will rust and be contaminated by dust.

8. New parts also need to be cleaned thoroughly before assembly.

9. During assembly, metal debris, fibers, grease (excluding those specified for use), dust, and other impurities, foreign objects, etc. should not be allowed to contaminate, adhere, or remain on the surface of the parts or enter the internal cavity.
