Flat valve seat disassembling and assembling tool

Abstract

The invention discloses a flat valve seat disassembling and assembling tool. The flat valve seat disassembling and assembling tool comprises a valve body and disassembling and assembling mechanisms installed at the water inlet end and the water outlet end of the valve body, the two disassembling and assembling mechanisms at the different ends are symmetrically arranged, a fluid channel is formed in the valve body, and mounting grooves are symmetrically formed in the middle of the fluid channel; wave springs are fixed to the ends in the mounting grooves, valve seats are fixed to the ends, closeto each other, of the wave springs, a valve plate is arranged between the valve seats, the disassembling and assembling mechanisms comprise connecting seats connected to the water inlet end and the water outlet end of the valve body in a threaded mode, mounting pipes are movably inserted into the axis of the connecting seats, and T-shaped rods are movably inserted into the mounting pipes; and circular pressing plates are fixed to the ends, close to each other, of the T-shaped rods, and rotating rods are fixed to the ends, close to each other, of the circular pressing plates. According to theflat valve seat disassembling and assembling tool, through the visual design, the internal condition of a flat valve can be known, the operation of a user is facilitated, the connection is simple, theoperation is simple, and the disassembling and assembling efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of disassembly and assembly of flat valves, in particular to a disassembly tool for valve seats of flat valves. Background technique [0002] The two end faces of the valve plate of the manual flat valve are sealing surfaces, and the valve seat adopts a wave spring to give the valve plate a pre-tightening force, relying on the free fit between the valve plate and the valve seat and the sealing grease, and realizes the seal under the action of the medium pressure, By turning the hand wheel, the valve plate can be lifted or lowered, which plays the role of connecting or cutting off the conveying medium channel. [0003] The valve seat must be disassembled and the seals replaced for maintenance of the flat valve. However, when removing the valve seat of the flat valve, the valve plate must be taken out first. The valve plate and the valve seat are separated. In the case of not damaging the valve plate, first t...

AI Technical Summary

Problems solved by technology

[0004] In the above process, since the valve seat does not have a special tool for disassembly and assembly, and the operation space is very small, there are great operational risks whether it is taking out or reassembling the valve seat, which is likely to cause injury to the operator's fingers and damage the valve. Seat damage, and time-consuming and labor-intensive, disassembly efficiency is very low, for this reason, the present invention proposes a flat valve seat disassembly tool to solve the above problems
