Abstract
The utility model discloses movable sealing pottery blade type gate valve, comprise valve body, valve seat, flashboard and push rod, valve body center is provided with flashboard, in described valve body, ceramic valve seat is installed, one side of ceramic valve seat is connected with valve seat trim ring, flashboard top is fixedly connected with by flashboard nut with push rod, the flashboard overcoat on valve body top has filler, compressed by Gland above filler, a land is provided with outside push rod top, land upper-end surface is connected with Pneumatic actuator, and land lower end surface is connected with support, props up and is set up in push rod outer surface.This technology is that ceramic material forms by valve seat and valve seat trim ring, and have the strong and sealing of good self-cleaning, super abrasive, deep-etching, self lubricity, Environmental Conditions is extensively especially suitable for use in chemical industry, substantially prolongs the working life of valve; This technology can reduce the maintain and replace number of times of valve greatly, improves the Security of corollary equipment operational system, stability, saves equipment repair expense.
Description
Technical field
The utility model relates to valve technology field, particularly relates to a kind of movable sealing pottery blade type gate valve.
Background technique
Known blade type gate valve is used for fibrous medium pipeline, be used for the keying of control media, its structure generally comprises valve body, valve seat, flashboard, valve rod, valve gap, transmission device, flashboard are blade type structure, in valve closing process, blade type gate valve plate scrapes off and cuts off particulate matter on valve seat and fibre object, reduces the wearing and tearing of flashboard and sealing surface of seat.And traditional blade type gate valve great majority are made by metallic material, corrosion blade type gate valve is easy to for the medium in chemical industry, valve is made to hold damage very much, and valve must be dismantled when keeping in repair, keep in repair more loaded down with trivial details, increase the maintenance difficulty of people, be corroded the sealing that greatly have impact on valve simultaneously, input increasing cost etc.
Model utility content
For the deficiencies in the prior art, the utility model aims to provide one can be applicable to the circulation of chemical industry Korrosionsmedium, has corrosion-resistant, the movable sealing pottery blade type gate valve of the better and convenient maintenance of sealability.
To achieve these goals, the technological scheme that the utility model is intended taking is: movable sealing pottery blade type gate valve, comprise valve body, valve seat, flashboard and push rod, valve body center is provided with flashboard, in described valve body, ceramic valve seat is installed, one side of ceramic valve seat is connected with valve seat trim ring, flashboard top is fixedly connected with by flashboard nut with push rod, the flashboard overcoat on valve body top has filler, compressed by Gland above filler, a land is provided with outside push rod top, land upper-end surface is connected with Pneumatic actuator, land lower end surface is connected with support, prop up and be set up in push rod outer surface.
Described valve seat trim ring is that ceramic making forms, and makes can not come off in ceramic valve seat trim ring and flashboard switch seal process, and sealability is better, and is convenient to change ceramic valve seat, makes energy-conserving and environment-protective more.
Described Gland and valve body are by screw bolt and nut fixing and locking, and concrete fixes locking Gland and valve body by four screw bolt and nut, is convenient to installation and removal on the one hand, decreases the difficulty of installation and removal, are also convenient to people and change and maintenance.
The beneficial effects of the utility model: compared with prior art, this technology is that ceramic material forms by valve seat and valve seat trim ring, there is the strong and sealing of good self-cleaning, super abrasive, deep-etching, self lubricity, Environmental Conditions is extensively especially suitable for use in chemical industry, substantially prolongs the working life of valve; This technology can reduce the maintain and replace number of times of valve greatly, improves the Security of corollary equipment operational system, stability, saves equipment repair expense.
