After the valve, go to the water distributor or this section of pipeline.
The difference between the entrance valve and the main valve: the entrance water pipe valve adopts a ball valve. The ball valve is evolved from the plug valve. Its opening and closing part is a sphere, which is used to rotate 90 degrees around the axis of the valve stem. degree to achieve the purpose of opening and closing. Ball valves are mainly used on pipelines to cut off, distribute and change the flow direction of media. Main valve: Use a stop valve, which refers to a valve whose closing member moves along the center line of the valve seat. Because the valve stem of this type of valve has a relatively short opening or closing stroke, it also has a very reliable shut-off function.
A valve is a mechanical device that controls the flow, direction, pressure, temperature, etc. of a flowing fluid medium. The valve is a basic component in the pipeline system. Valve fittings are technically the same as pumps and are often discussed as a separate category. The valve can be operated manually or by hand wheel, handle or pedal, and can also be controlled to change the pressure, temperature and flow rate of the fluid medium. Valves can provide continuous or repeated operation in response to these changes, such as safety valves installed in hot water systems or steam boilers. In more complex control systems, automatic control valves are used based on external input needs. The automatic control valve does not require manual operation according to its input and settings, so that the valve can accurately control various requirements of the fluid medium. According to the material, valves are also divided into cast iron valves, cast steel valves, stainless steel valves, chromium molybdenum steel valves, chromium molybdenum vanadium steel valves, duplex steel valves, plastic valves, non-standard customization and other valve materials.
