Problems solved by technology

[0003] However, the traditional two-piece ball valve is connected to the flange by two bolts in the middle, and is only completely sealed by the angular structure of the equipment parts. During the opening and closing process of the valve body, the wear resistance is not good, the valve body is gradually worn out, and there are many leakage points , it is even more impossible to achieve reliable sealing, which increases equipment maintenance costs and makes maintenance difficult

Abstract

The invention discloses a dually-connected three-way valve and belongs to the technical field of valves. The dually-connected three-way valve comprises a valve body which is composed of two mutually connected three-way valve bodies, and each three-way valve body comprises one three-way valve inlet and two three-way valve outlets; the two three-way valve bodies are fixed on a shaft and are mutually separated through a partition which is arranged on the shaft through a support sleeve; each of the upper end and the lower end of the valve is provided with a valve body cover plate, a valve bonnet used for sealing is arranged on the valve body cover plate on the upper portion of the valve body, and a rear valve seat cover plate used for fixing and sealing is arranged at the bottom of the valve body cover plate on the lower portion of the valve body; two pairs of valve plate assemblies fittingly used with the two three-valve inlets are respectively arranged on the shaft. By the arrangement, perfect sealing of the dually-connected three-way valve is realized, the dually-connected three-way valve is durable, simple and compact in structure, easy and convenient to mount and maintain, reliable in sealing, long in service life of equipment, easy to maintain and preserve and good in practicability.

Description

technical field [0001] The invention belongs to the technical field of valves, and in particular relates to a double three-way valve. Background technique [0002] Ball valves are widely used in petroleum refining, long-distance pipelines, chemical industry, papermaking, pharmaceuticals, water conservancy, electric power, municipal, steel and other industries. Ball valves are mainly used in pipelines to cut, distribute and change the flow direction of media. It can rotate 90 degrees. The cock body is a sphere with a circular through hole or channel passing through its axis. [0003] However, the traditional two-piece ball valve is connected to the flange by two bolts in the middle, and is only completely sealed by the angular structure of the equipment parts. During the opening and closing process of the valve body, the wear resistance is not good, the valve body is gradually worn out, and there are many leakage points , It is even more impossible to achieve reliable sealin...
