Abstract

The invention belongs to the technical field of valve devices, and particularly relates to a novel valve rod joint device. The novel valve rod joint device comprises a flat and straight valve rod barrel body, wherein the front end of the valve rod barrel body is provided with a joint assembly, and the rear end of the valve rod barrel body is provided with a support arm assembly; the joint assemblycomprises a first folded plate provided with a first forwards extending plate at the front part and a first backwards extending plate at the rear part, and a second folded plate provided with a second forwards extending plate at the front part and a second backwards extending plate at the rear part; , opposite connection holes are formed in the first folded plate and the second folded plate; connection bolts are arranged in the connection bolts; the first backwards extending plate and the second backwards extending plate are inserted into an inner cavity of the front part of the valve rod barrel body and then are welded and fixed; a filler is also arranged between the first backwards extending plate and the second backwards extending plate; the support arm assembly comprises a first support arm and a second support arm; and the front ends of both the first support arm and the second support arm are connected with the rear end of the valve rod barrel body in a hinged manner through a rotating shaft.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing equipment, and in particular relates to a valve stem joint device. Background technique [0002] A valve stem is generally installed on the valve to operate the internal action components. Generally, a joint is provided at the front end of the valve stem. The joint is used to be fixedly connected with the action element of the valve. The opening and closing of the valve can be controlled by moving the valve stem. adjust. The joint is made by bending a metal plate. The fastening part with bolts and the connection part for fixing the valve stem are respectively formed at both ends, and the regular hexagonal shape is formed in the middle part to be sleeved on the valve action element. The regular hexagon is connected on the axis. The existing valve stem joint device generally has a single function, which is unfavorable for operation. Contents of the invention [0003] In order to s...
