Description

Turbine butterfly valve Technical Field The utility model relates to the technical field of valves, in particular to a turbine butterfly valve. Background The turbine butterfly valve is a valve for regulating fluid on-off by controlling rotation of a butterfly plate through a turbine driving device, the core structure of the turbine butterfly valve comprises a valve body, a disc-shaped butterfly plate and a turbine transmission mechanism, the butterfly plate can be fully opened or fully closed by rotating 90 degrees around a valve shaft, the turbine driving device adopts a worm and gear design, torque can be obviously reduced when the turbine driving device is operated through a hand wheel, and the butterfly valve is used as a key fluid control device in an industrial pipeline system. The integrated forming structure is generally adopted in the conventional butterfly valve seat, impurities are accumulated on the surface of the valve seat or abrasion occurs in the design, when the valve is required to be cleaned or replaced, the valve is required to be completely disassembled from a pipeline system, core components such as a valve body, a valve rod and a valve plate are comprehensively disassembled, the process involves complex disassembly procedures of a plurality of components, maintenance personnel are required to synchronously disassemble the valve body and the valve rod connecting components during operation, and a large amount of manpower and material resources are consumed. Disclosure of utility model The utility model aims to provide a turbine butterfly valve, which solves the problems that a valve is required to be completely detached from a pipeline system and a large amount of manpower and material resources are consumed when the valve seat of the traditional butterfly valve is generally in an integrated forming structure and is in need of cleaning or replacement. In order to achieve the above purpose, the present utility model provides the following technical solutions: The utility model provides a turbine butterfly valve, includes valve body and valve plate, the surface mounting of valve body has the disk seat subassembly, the rotatable inboard that sets up in the disk seat subassembly of valve plate, the disk seat subassembly includes preceding disk seat and back disk seat, the back fixedly connected with tenon of preceding disk seat, the through-hole that supplies the tenon to pass is seted up to the surface cooperation of back disk seat, preceding disk seat, tenon, back disk seat all adopt the rubber material, the fixed surface of tenon is connected with a plurality of evenly distributed's pull rings. Preferably, the tenon can be lapped on the surface of the rear valve seat after passing through the through hole. Preferably, the surfaces of the front valve seat and the rear valve seat facing the valve body are respectively provided with a plurality of uniformly distributed positioning convex blocks, and the surfaces of the valve body are correspondingly provided with positioning grooves for the positioning convex blocks to be inlaid. Preferably, the reduction gearbox is installed to the top surface of valve body, the surface rotation of reduction gearbox is connected with the hand wheel, the surface pin joint of valve body has the valve rod, the hand wheel passes through the gear drive mechanism of reduction gearbox and drives the valve rod rotation, the valve rod runs through valve seat subassembly and with valve plate fixed connection.
