Description
Technical field
This utility model relates to valve technology field, particularly relates to a kind of self sealss swing type non-return valve.
Background technology
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, 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 flowing backwards, preventing pump
And drive motor reversion, and the releasing of vessel media.
At present, the flap on non-return valve and be connected between valve rod and there is gap, easily produce in the case of long-term stress
Leakage, mainly due to being that face contacts between valve rod with flap, easily produces gap after stress deformation.
Utility model content
This utility model to solve the problem that above-mentioned prior art exists, it is provided that a kind of self sealss swing type non-return valve, valve
Lobe adapts to the deformation of stress with valve rod junction, automatically generates the contact surface of sealing, strengthens sealing.
This utility model solve its technical problem use technical scheme: this self sealss swing type non-return valve, including valve
Body, valve gap, be provided with the passage that left and right communicates, be provided with valve seat, be rotatably connected to join with valve base sealing in valve body in passage in valve body
The flap closed, is rotatably connected to valve rod in valve body, the lower end of valve rod has fixing hole, and flap is provided through the fixing of fixing hole
Post, the outer end of fixing post is provided with clamp nut, and the inwall of fixing hole is protruding arcwall face structure, and the outer wall of fixing post is convex
Rise arcwall face structure and with fixing hole inwall be in close contact.Contact between fixing hole with fixing post for linear contact lay, fixing hole
Inwall and fixing column outer wall all use the arcwall face of projection, adapt to stress deformation, and ensure sealing in the way of linear contact lay.
In order to 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 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, structure
Reasonable in design.
The most perfect, valve seat is for tilting to install, and the angle of inclination of valve seat is 5-8 degree.Sample flap is fitted in more closely
On valve seat.
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.So strengthen the sealing between valve seat and mounting groove.
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 and valve rod junction adapt to the deformation of stress, automatically
Producing the contact surface sealed, strengthen sealing, valve seat is more fitted with flap, strengthens sealing, and in valve seat, outer face is all pacified
Dress sealing ring, reasonable in design, overall tightness is good, is conducive to being widely popularized.
