How to install the ball valve?

The ball valve is a device used in the pipeline to cut off, distribute and change the direction of the medium. In use, it only needs to rotate 90 degrees and a small torque can be closed tightly. What should I pay attention to when using the ball check valve or brass ball valve? Here are some precautions for the use of the ball valve, I hope it can help you.

 

   

Instructions for use of ball valves

1. It is necessary to find out that the upstream and downstream pipelines of the ball valve have indeed relieved the pressure before disassembling.

 

2. Non-metal parts should be taken out of the cleaning agent immediately after cleaning, and should not be soaked for a long time.

 

3. The bolts on the flange must be tightened symmetrically, gradually and evenly during assembly.

 

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

 

5. Every single ball valve part decomposed can be cleaned by dipping. Metal parts with undecomposed non-metal parts can be scrubbed with a clean, fine silk cloth impregnated with cleaning agent (to prevent fibers from falling off and adhering to the parts). When cleaning, all grease, dirt, glue, dust, etc. adhering to the wall must be removed.

 

 6. When the motorized ball valve is disassembled and reassembled, care must be taken to prevent damage to the sealing surface of the parts, especially non-metal parts. Special tools should be used when removing the O-ring.

 

7. After cleaning, it needs to be assembled after the cleaning agent of the washed wall surface is volatilized (can be wiped with silk cloth not soaked in cleaning agent), but it must not be left for a long time, otherwise it will rust and be contaminated by dust.

 

 

Ball valve installation

1. Install the apollo ball valves and stainless steel ball valve on the pipeline. Any end of the ball valve can be installed on the upstream end. The ball valve driven by the handle can be installed at any position on the pipeline. But the gear box or pneumatic ball valve should be installed upright, that is, installed on the horizontal pipeline, and the drive device is above the pipeline.

 

2. Install a gasket between the valve flange and the pipeline flange according to the pipeline design requirements.

 

3. The bolts on the flange should be tightened symmetrically, successively and evenly.

 

4. Connect the pneumatic pipeline (when using a pneumatic driver).

 

 

Inspection after installation of ball valve

1. Operate the driver to open and close the ball valve several times. It should be flexible and free of stagnation to confirm its normal operation.

2. Check the sealing performance of the flange joint surface between the pipeline and the ball float valve according to the pipeline design requirements.
