Abstract

The invention discloses a shifting fork type butterfly valve. The shifting fork type butterfly valve comprises two parallelly arranged fixing plates. Fixed blocks are fixedly connected to the two sides of each of the two fixing plates correspondingly, the sides, away from the fixing plates, of the fixed blocks are of arc-shaped structures protruding outwards, embedded blocks are arranged at the two ends of each fixed block in a clamped mode correspondingly, connecting rods are inserted into the embedded blocks, and the connecting rods penetrate through the embedded blocks to be connected withthe fixed blocks; shifting fork devices are arranged between the fixing plates and the fixed blocks, two parallelly arranged sealing blocks are arranged on each shifting fork device, and the two endsof each sealing block abut against the fixing plates; and installation blocks are fixedly connected to the side walls of one opposite sides of the sealing blocks correspondingly, and two parallelly arranged connecting blocks are fixed to the side, away from the corresponding sealing block, of each installation block. According to the shifting fork type butterfly valve, the structure is simple, operation is convenient, the airtightness between the butterfly valve and a connecting pipe is improved based on an existing shifting fork type butterfly valve structure, the water leakage possibility isreduced, and the working efficiency of the butterfly valve is improved.

Description

technical field [0001] The invention relates to the technical field of butterfly valves, in particular to a fork type butterfly valve. Background technique [0002] Butterfly valve, also known as flap valve, is a regulating valve with simple structure, which can be used for switching control of low-pressure pipeline medium. A kind of valve, the valve can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media. It mainly plays the role of cutting and throttling on the pipeline. The opening and closing part of the butterfly valve is a disc-shaped butterfly plate, which rotates around its own axis in the valve body, so as to achieve the purpose of opening and closing or adjustment. Most of the current butterfly valves are opened and closed by a fork structure or a gear structure. And its outlet is often connected by connecting pipe, but the connection between connecting pipe and bu...
