The ball valve is more suitable for water treatment and environmental protection systems. It is an ideal product. Many people may not know this product. Then I will give you a brief introduction to the ball valve. The electric explosion-proof butterfly valve is composed of a V-type valve body, a ZSQ-type pneumatic actuator and other accessories. It is an advanced control valve with a right-angle rotation structure. The V-type ball valve does not need to be repaired for a long time and has a long service life, which provides you with real high efficiency A valve that controls the process conditions.
1. The bottom end connecting pipe and the plug that play the role of draining function can be connected by threads. When the temperature continues to rise, it is difficult to guarantee the thread and part of the sealing system. It is decided that the enterprise should cancel the plug and effectively connect the plug to the bottom end pipe. The head is replaced with a stepped sewage plug, and the connecting end is analyzed and sealed with a winding gasket to ensure the reliability of the sealing work at the bottom of the society. A valve in which the disc of a knife gate valve slides along the center line of the valve body. In-line check valve is a new type of valve.
The situation of valve industry in Wenzhou City China and its future development. China's valve industry started late, but developed rapidly. At present, there are some shortcomings in some conveniences. If we improve these in the future, we will make greater progress.
The first valve structure in the form of the elastic ball valve 1 distinguishes: the ball valve is elastic. The high temperature check valve is a kind of automatic valve, the main function is to prevent the medium from flowing back, prevent the pump and the drive motor from reversing, and to discharge the container medium. According to the usage conditions of the American standard check valve, the disc can be an all-metal structure, or it can be in the form of a rubber pad or a rubber ring inlaid on the disc holder. Lift check valves can be divided into swing check valves (rotating according to the center of gravity) and lift check valves (moving along the axis).
The first pneumatic three-way welded flange ball valve and ball valve are suitable for PN1.0 connection to 4.0MPa. A valve in which the valve flap of a pneumatic check valve slides along the center line of the valve body. In-line check valve is a new type of valve. It is small in size, light in weight, and good in processing technology. It is one of the development directions of check valves. But the fluid resistance coefficient is slightly larger than that of the swing check valve.
The assembly requirements of the check valve are very high, so that we can ensure the stable development of the follow-up management work, so how can the company install the check valve effectively?
In the maintenance of the fluorine-lined globe valve, the correct disassembly is very important. Only the correct disassembly can play its role to ensure the valve's role in production. So what should be paid attention to during the disassembly and assembly process? Let us find out with the manufacturer. The maximum flow volume of the electric cut-off ball valve: Due to its streamlined layman and full right-angle rotation control, the maximum volume is particularly high,
For example, stop valve, throttle valve, pressure reducing valve, check valve, etc., if installed upside down, it will affect the use effect and life (such as throttle valve), or it will not work at all (such as pressure reducing valve), or even Cause danger (such as check valve). -General valve, there are direction signs on the valve body. If not, it should be correctly identified according to the valve working principle.The valve cavity of the globe valve is asymmetrical from left to right.
Thermal power plant valve pressure plugging technology. Power plant valves are mainly used to control the operation of various equipment and fluid media on their pipelines. Valve leakage often occurs in packing, flange seals and valve bodies. Long-term valve leakage can cause The erosion of the valve stem and flange sealing surface will eventually cause the valve to be scrapped. In addition, the valve plugging technology under pressure for the medium fluid thermal power plant. Power plant valves are mainly used to control the operation of fluid media on various equipment and pipelines. Valve leakage often occurs on packing, flange seals and valve bodies. Long-term valve leakage can cause the valve stem and flange sealing surface to be flushed.
