Direct sales of gas source card sleeve ball valve

Direct sales of gas source card sleeve ball valveStructure description:
1) The card sleeve ball valve has a smooth and flat channel, which is convenient for pipeline cleaning and can transport media such as slurry and solid particles.
2) Using PTFE (Teflon) and other materials as seals, it has good lubrication and elasticity, low friction with the sphere, and long service life.
3) Quick opening and closing, simply rotate the sphere 90 ° for convenient and quick opening and closing.
4) The fluid resistance of the cartridge ball valve is small. When fully opened, the cross-sectional areas of the ball channel, valve body channel, and connecting pipeline are equal and straight, and the medium flows through the cartridge ball valve, which is equivalent to flowing through a straight pipe. Among various types of valves, the fluid resistance of the cartridge ball valve is min.

Maintenance precautions:
1. In the closed state of the sleeve ball valve, there is still pressurized fluid inside the valve body.
Before repairing the sleeve ball valve, release the pipeline pressure and keep the valve in the open position.
Before maintenance, disconnect the power or gas source.
Before maintenance, detach the actuator from the bracket.
5. It is necessary to confirm that the upstream and downstream pipelines of the sleeve ball valve have been depressurized before proceeding with disassembly and assembly operations
6. When disassembling and reassembling, care must be taken to prevent damage to the sealing surface of the parts, especially non-metallic parts. Tools should be used when removing the O-ring
7. When assembling the ball valve, the bolts on the flange must be tightened symmetrically, gradually, and evenly.
8. 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 can be used to clean metal parts. Clean non-metallic parts with pure water or alcohol

Direct sales of gas source card sleeve ball valveIt does not require welding when connected to steel pipes, which is beneficial for fire prevention, explosion prevention, and high-altitude operations, and can eliminate the drawbacks caused by careless welding. Weijing Machinery specializes in producing card sleeve connectors. Therefore, it is a relatively reliable connecting component in the piping of automatic control devices in refining, chemical, petroleum, natural gas, food, pharmaceutical, instrumentation and other systems. Suitable for connecting pipelines such as oil, gas, and water.

Ball valve installation instructions:
1. The pipelines before and after the ball valve are ready. The front and rear pipelines should be coaxial, and the sealing surfaces of the two flanges should be parallel. The pipeline should be able to withstand the weight of the ball valve, otherwise appropriate support must be provided on the pipeline.
2. Blow clean the pipelines before and after the valve, remove oil stains, welding slag, and all other impurities from the pipeline.
3. Check the markings of the ball valve to ensure that it is intact and undamaged. Fully open and close the valve several times to confirm its normal operation.
4. Remove the protective components from the connecting flanges at both ends of the ball valve.
