The lower end of the valve cover 2 is fixedly connected to the upper end of the valve body 1. The valve ring assembly 3 is installed inside the valve body 1 and the valve cover 2. The valve ring assembly 3 includes a large valve ring 31, a medium valve ring 32, and a small valve ring 33. Several through-holes vent 21 are opened on the end face of the valve cover 2, and a bolt hole 22 is opened at the center of the end face of the valve cover 2. An inner fixing post 11 and an outer fixing post 12 are formed inside the valve body 1. A fixing cylinder 14 is formed at the center of the inside of the valve body 1, and a threaded hole is opened inside the fixing cylinder 14. 141. Fastening bolts 4 are fixed through bolt holes 22 and threaded holes 141. Large valve ring 31 is installed between the inner wall of valve body 1 and outer fixed post 12. Medium valve ring 32 is installed between outer fixed post 12 and inner fixed post 11. Small valve ring 33 is installed between inner fixed post 11 and fixed cylinder 14. An inner sealing gasket 5 is provided on the top surface of fixed cylinder 14. An outer sealing gasket 6 is provided on the outer end face of valve body 1.
