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.
