The valve is a kind of pipeline accessories, it is used to change the pipeline section and medium flow direction, control the conveying medium pressure, flow, temperature one kind of device, specifically speaking, it has the following uses:
1. Connect or cut off the medium in each section of the pipeline, such as: gate valve, globe valve, butterfly valve, ball valve, cock, etc.
2. Adjust the flow and pressure of the pipeline, such as: regulating valve, throttle valve, pressure reducing valve, butterfly valve, ball valve, etc.
3. Change the direction of medium flow, such as: distribution valve, three-way cock, three-way ball valve, etc.
4. For overpressure protection, such as: safety valve, relief valve.
5. Prevent the media flow back in the pipeline, such as: check valve
6. Indicate and adjust liquid level, such as: level indicator, level regulator, etc.
7. Separate gas and water in the pipeline, such as steam trap and air trap.
8. The temperature regulation in the pipeline, such as: temperature regulating valve, temperature reducing and pressure reducing device.
Various safety valves in the long-term use of management process, and stainless steel flange ball valve at the same time, enterprises may be subject to certain damage, so how do we manage it? Taizhou Shangyi Valve Co., Ltd.Our manufacturer suggests that we take you to understand the valve repair work method. The 3360 V valve is a removable metal valve with self-correcting features, good sealing and long service life. Electric explosion-proof ball valve is widely used in petroleum, chemical, electric power, paper making, metallurgy and other industries. Pneumatic knife gate valve is used with the valve positioner right Angle rotary regulating valve.
1. Soft sealing ball valve is usually used as sealing material, and hard sealing ball valve is sealed on the metal surface. When the pipe ball valve needs to be cleaned, be careful to remove it to prevent damage and leakage of the seal.
2. If there is a slight leakage of the filling material during use, please tighten the stem nut slightly before stopping the leakage and do not tighten it again.
3. Before use, clean the pipeline and the body flow parts with water to prevent debris such as residual iron scraps from entering the body cavity.
4. Ball valve closed, the valve to maintain part of the medium, under a certain pressure.
5. Long-term open air storage before maintenance of the ball valve will make the valve body and parts rust, can not be used normally. The storage of the ball valve is rainproof, waterproof, moisture-proof and the tightness of the flange cover.
6. If there is a slight leakage of the filling material during use, the stem nut should not be tightened until the leakage stops.
Therefore, depending on the situation, different maintenance balls need to be performed to ensure the performance of the ball.
