Abstract
The utility model 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 arc-shaped structure of one side of the flap towards valve seat；Flap wears axis pin bore portion showing ellipsoidal structure.The beneficial effects of the utility model are：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 utility model 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 currently on 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 at the same time
Automatic guide acts on, flap and sealing surface of seat cannot good automatic alignment, flap and valve base seal property are subject to one fixing
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 performance for improving flap is problem to be solved.
Utility model content
Technical problem to be solved in the utility model is：A kind of clamp connection swing check valve is provided.Use the card
Hoop connection swing check valve can not only mitigate the weight of flap, improve flap bearing strength, improve flap in closing process
Automatic guide effect, make flap and sealing surface of seat automatic alignment, improve the sealing performance of flap.
The utility model solve above-mentioned technical problem technical solution be：A kind of clamp connection swing check valve, including
Valve body, flap, valve seat, the valve body are provided with groove on opposite both ends outer surface, it is characterized in that：The flap uses stainless
316 material punching press of steel is made, the arc-shaped structure of one side of the flap towards valve seat；It is oval that the flap wears axis pin bore portion
Structure；
The valve body also has the 3rd end, and groove, the valve body tool are provided with the 3rd end outer surface which 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 lower part of valve seat one side.
The beneficial effects of the utility model are：Since the flap of the utility model is made using Stainless steel 316 material punching press,
The weight of flap is alleviated, flap is relative to flap weight made of existing cast iron materials made of Stainless steel 316 material punching press
Mitigate 20-25%, improve flap bearing strength；And the arc-shaped knot of one side of flap towards the valve seat due to the utility model
Structure, make flap in closing process can automatic guide, make flap and sealing surface of seat automatic alignment, improve flap and valve seat
Sealing performance；Again since the flap of the utility model wears axis pin bore portion showing ellipsoidal structure, effectively avoid because of pin shaft hole
Mismachining tolerance causes flap and sealing surface of seat can not improve assembly qualified rate to direct problem.
Again since the valve body of the utility model also has the 3rd end, ditch is provided with the 3rd end outer surface which has
Groove, the groove that the 3rd end which has is set in appearance can be directly connected using hoop component with groove pipe fitting；Overcome
Mostly the 3rd end connection of clamping hoop type connection check-valves with the 3rd end currently on the market is middle flange bolt connection, this to have
3rd end and dismounting is complicated when being the clamping hoop type connection check-valves maintenance of middle flange bolt connection, bothersome laborious, maintenance efficiency is low
Technical 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 lower part of valve seat one side
Face.Since the sealing of valve seat and the flap is in linear sealing, and vulcanizes rubber quality and stablize, service life time length, improves
The seal and service life of the utility model flap and valve seat.Again since the flap vulcanizes backwards to the lower part of valve seat one side
Rubber sealing surface, when flap is all turned on flap vulcanize played when body cavity is encountered in the part of rubber sealing surface it is spacing
Buffering, protects flap and valve body, improves the service life of the utility model.
