Further, described bonnet, and described cover plate are bolted.
Further, described adjustment spring end is provided with joint pin, and described joint pin is connected through the described lid that seals with described seal, regulates spring and regulates the switch of cone plug and control hole by driving seal to move.
Further, the surface that described valve body, spool contact with fluid is equipped with corrosion-inhibiting coating.
The beneficial effects of the present invention is:
The adjustment spring end of the present invention is provided with joint pin, and joint pin is connected through the described lid that seals with seal, regulates spring and regulates the switch degree of cone plug and control hole by driving seal to move, thus realizing valve decompression work；Water outlet pipeline tapered increasing gradually is thick, and blocking ball is fixed in pipeline by spring, can prevent reverse flow of fluids；Blocking pipeline between ball, filtration core is provided with sewage and flows out pipeline, and sewage flows out pipeline and is provided with stop valve, filtration core can carry out backflow at any time and clean, and flows out pipeline by sewage and discharge cleaning sullage, extends valve service life.
