Description

Technical Field

[0001] The utility model relates to the technical field of valve castings, in particular to a valve casting which is convenient to disassemble. Background Art

[0002] Valve pipeline devices are devices used to control the direction, pressure, and flow of fluid in fluid systems. They are devices that make the medium in piping and equipment flow or stop and can control its flow. Valves are control components in pipeline fluid transportation systems and are used to change the cross-section of the passage and the direction of medium flow. The control of valve pipelines can adopt a variety of transmission methods.

[0003] For example, the Chinese utility model provides "a valve casting that is easy to disassemble", and its announcement number is: CN209414718U, which includes a valve body, and blocks are provided on the left and right sides of the valve body. The left and right sides of the water inlet pipe and the water outlet pipe are respectively detachably connected to the left and right sides of the valve body by bolts a; when water flows into the valve body from the water inlet pipe, the filter screen filters out the residue in the water, thereby preventing the residue in the water from clogging the valve body. After water flows into the valve body, the baffle inside the valve body slows down the rush of the water flow, preventing the impact force of the water from damaging the valve body casting and the pipeline. When people need to maintain the valve body, they rotate bolt a to remove bolt a from the outer surface of the valve body, rotate the valve body to remove the block from the slot, thereby removing the valve body, and open the sealing cover by rotating bolt b, thereby repairing or replacing the inside of the valve body, so that people do not need to waste a lot of time and physical strength to maintain it.
