Description
Technical field
This utility model relates to valve technology field, particularly relates to a kind of protecting against shock elasticity swing type non-return valve.
Background technology
At present, non-return valve refers to rely on medium itself to flow and automatic open and close valve plate, is used for the valve preventing medium from flowing backwards
Door, also known as check valve, reflux valve and counterbalance valve.Non-return valve belongs to a kind of automatic valve, and its Main Function is to prevent medium from falling
Stream, prevent pump and drive motor reversion, and the releasing of vessel media.Valve seat on non-return valve is fixed in valve body at present,
All sealed by sealing ring between valve seat and flap, and valve seat itself is the firmest, sealing between valve seat and flap
Easily shaken or other factors are caused certain leakage, affected sealing.
Utility model content
This utility model to solve the problem that above-mentioned prior art exists, it is provided that a kind of protecting against shock elasticity swing type check
Valve, between valve rod with flap, elasticity is connected, and makes flap be resiliently sealed on valve seat, strengthens sealing.
This utility model solve its technical problem use technical scheme: this protecting against shock elasticity swing type non-return valve, bag
Include valve body, valve gap, be provided with the passage that left and right communicates in valve body, be provided with valve seat in passage, be rotatably connected to close with valve seat in valve body
The flap that envelope coordinates, is rotatably connected to valve rod in valve body, the lower end of valve rod has fixing hole, and flap is provided through fixing hole
Fixing post, the outer end of fixing post is provided with clamp nut, is provided with flexure strip between clamp nut and valve rod.So flap is fixing
There is on post certain Elastic Sliding space, make Elastic Contact between flap and valve seat, it is to avoid vibrations or the impact of other factors seal
Property.
In order to the most perfect, the inwall of fixing hole is protruding arcwall face structure, and the outer wall of fixing post is protruding arc
Shape face structure is also in close contact with fixing hole inwall.Contact between fixing hole with fixing post for linear contact lay, fixing hole inwall and
Fixing column outer wall all uses the arcwall face of projection, adapts to stress deformation, and ensures sealing in the way of linear contact lay.
The most perfect, the top in valve body is provided with fixing seat, and fixing seat is fixed with the union joint downwardly extended, valve rod
It is rotatably connected on union joint.The upper end of valve rod is rotatably connected in valve body by union joint, installs simple and convenient, and structure designs
Rationally.
The most perfect, valve seat inner face is provided with inner seal ring, and flap is provided with and seals, with inner seal ring, the valve coordinated
Flap seal circle.So strengthen the sealing between valve seat and flap by sealing ring.
The most perfect, it is provided with the mounting groove of fixed valve base in valve body, in mounting groove, is provided with exterior seal ring, valve seat outer face
Being provided with the sealing surface of inclination, exterior seal ring is fitted with sealing surface.
The most perfect, mounting groove is for being inclined in valve body, and valve seat is for tilting to install.
This utility model has the advantages that: this utility model flap has certain Elastic Sliding space on fixing post,
Make Elastic Contact between flap and valve seat, it is to avoid vibrations or other factors affect sealing;Valve seat is more fitted with flap, strengthens
Sealing, in valve seat, outer face is respectively mounted sealing ring, reasonable in design, and overall tightness is good, is conducive to being widely popularized.
