Abstract
The invention discloses a kind of clamp connection swing check valve.A kind of clamp connection swing check valve, including valve body, flap, valve seat, flap are made using Stainless steel 316 material punching press, the curved structure of one side of the flap towards valve seat；Flap wears bearing pin bore portion showing ellipsoidal structure.The beneficial effects of the invention are as follows：The weight of flap is alleviated, improves flap bearing strength；Make flap in closing process can automatic guide, make flap and sealing surface of seat automatic alignment, improve flap and valve base seal property；Assembly qualified rate can not be improved with sealing surface of seat to direct problem by also effectively avoiding the flap caused by pin shaft hole mismachining tolerance.
Description
Technical field
The invention belongs to a kind of check-valves, especially belongs to a kind of clamp connection swing check valve.
Background technology
The valve flap structure of clamp connection swing check valve is mostly that cast iron materials are made in the market, heavier, and
And bearing strength does not reach design requirement also sometimes.The flap of clamp connection swing check valve lacks in closing process simultaneously
Automatic guide acts on, flap and sealing surface of seat can not good automatic alignment, flap is fixing by one with valve base seal property
Ring.How to mitigate the weight of flap, improve flap bearing strength, how to improve automatic guide of the flap in closing process and make
With making flap and sealing surface of seat automatic alignment, the sealing property for improving flap is to need to solve the problems, such as.
The content of the invention
The technical problems to be solved by the invention are：A kind of clamp connection swing check valve is provided.Connected using the clip
The weight of flap can not only be mitigated by connecing swing check valve, improve flap bearing strength, improve flap in closing process from
Action-oriented acts on, and makes flap and sealing surface of seat automatic alignment, improves the sealing property of flap.
The present invention solve above-mentioned technical problem technical scheme be：A kind of clamp connection swing check valve, including valve body,
Flap, valve seat, the valve body are provided with groove on relative both ends outer surface, it is characterized in that：The flap uses Stainless steel 316
Material punching press is made, the curved structure of one side of the flap towards valve seat；The flap wears bearing pin bore portion showing ellipsoidal structure；
The valve body also has the 3rd end, and groove, the valve body tool are provided with the 3rd end outer surface that the valve body 1 has
The groove that the 3rd end having is set in appearance can be directly connected using hoop component with groove pipe fitting；
Vulcanize rubber sealing surface on the sealing surface of seat, the flap with the sealing surface excircle of the valve base sealing
Vulcanize rubber seal, the cross section of the rubber seal is O-shaped；The rubber sealing surface that the valve seat vulcanizes and the flap
On the O-shaped rubber seal that vulcanizes be in linear sealing；The flap vulcanizes rubber sealing surface backwards to the bottom of valve seat one side.
The beneficial effects of the invention are as follows：Because the flap of the present invention is made using Stainless steel 316 material punching press, valve is alleviated
The weight of valve, flap is relative to flap weight saving 20- made of existing cast iron materials made of Stainless steel 316 material punching press
25%, improve flap bearing strength；Again due to the curved structure of one side of flap towards valve seat of the invention, closing flap
During closing can automatic guide, make flap and sealing surface of seat automatic alignment, improve flap and valve base seal property；And by
Wear bearing pin bore portion showing ellipsoidal structure in the flap of the present invention, effectively avoid caused by pin shaft hole mismachining tolerance flap with
Sealing surface of seat can not improve assembly qualified rate to direct problem.
Again because the valve body of the present invention also has the 3rd end, groove is provided with the 3rd end outer surface that the valve body has,
The groove that the 3rd end that the valve body has is set in appearance can be directly connected using hoop component with groove pipe fitting；Overcome at present
It is middle flange bolt connection mostly that in the market, which has the three-terminal link of the clamping hoop type connection check-valves at the 3rd end, this to have the 3rd
Hold and dismantle complicated, bothersome laborious, the low skill of maintenance efficiency when being the clamping hoop type connection check-valves maintenance of middle flange bolt connection
Art problem；The purpose being easy to remove and repair is realized, improves maintenance efficiency.
Again due to vulcanizing rubber sealing surface, the sealing surface excircle of the flap and the valve base sealing on sealing surface of seat
On vulcanize rubber seal, the cross section of the rubber seal is O-shaped；The rubber sealing surface that the valve seat vulcanizes and the valve
The O-shaped rubber seal vulcanized on valve is in linear sealing；The flap vulcanizes rubber seal backwards to the bottom of valve seat one side
Face.Because the sealing of valve seat and the flap is in linear sealing, and vulcanize rubber quality stabilization, service life time length, improve
The seal and service life of flap and valve seat of the present invention.Again because the flap backwards to the bottom of valve seat one side vulcanizes rubber
Sealing surface, when flap is all turned on flap vulcanize served when body cavity is encountered in the part of rubber sealing surface it is spacing slow
Punching, protects flap and valve body, improves the service life of the present invention.
