进口双向承压偏心半球阀Inlet two-way pressure bearing eccentric hemispherical valve

Product Description:

Including valve body, valve cover, valve seat, spherical valve plate, spherical crown, upper valve shaft, upper shaft sleeve, lower valve shaft, lower shaft sleeve and driving device; The valve cover is provided with a packing culvert, and a packing gland bolted to the valve cover is arranged above the valve cover. A packing is arranged between the packing gland and the packing culvert, and a thrust washer is arranged between the upper valve shaft and the packing culvert; The end of the lower valve shaft away from the spherical valve plate is provided with an adjusting four open ring, the adjusting four open ring is provided with a plurality of first screw holes, and the first screw holes are respectively provided with a first adjusting screw and a locking screw; The valve seat comprises a hard sealing valve seat and a soft sealing valve seat, and the soft sealing valve seat comprises a first sealing ring and a support ring. With this structure, the valve core is not easy to lock, and the valve can be opened easily and laboriously. Multiple insurance is adopted to ensure the sealing performance and prevent leakage, and online adjustment can be carried out according to different conditions.

进口双向承压偏心半球阀characteristic:

The valve is the control component in the fluid transmission system, which has the functions of cut-off, regulation, diversion, prevention of backflow, pressure stabilization, diversion or overflow pressure relief. Valves range from the simplest stop valve to various valves used in extremely complex automatic control systems, with a wide variety of varieties and specifications. The ball valve is one of the valves. The eccentric hemispherical valve is one of the ball valves. It is divided into hard seal eccentric hemispherical valve, soft seal eccentric hemispherical valve, soft and hard seal eccentric hemispherical valve, etc. according to the sealing direction, it is divided into one-way seal and two-way seal. During the use of the eccentric hemispherical valve in the prior art, the valve core is easily locked due to environmental changes, and the upper and lower valve shafts may leak out. The pressure ring pressing the valve seat is easy to deform under high pressure, and it is difficult to adjust the valve online.
