Description
Technical field
The utility model, which provides, a kind of to be applied to the industry conveying high-pressure media such as oil, chemical industry to be automatically prevented from medium anti-
To the forging high-pressure check valve of flowing.
Technical background
At present, domestic high-pressure check valve is typically made up of major parts such as valve body, bonnet, valve seat, flap, springs, valve
Seat is arranged in valve body, and for sealing surface of seat using built-up welding or a kind of metal material of welding on valve body, sealing surface of seat processing is tired
Difficult, crudy is not easy to ensure, under high pressure operating mode and easily by medium erosion failure, seal failure.
The content of the invention
The purpose of this utility model is to overcome existing check valve receptacle to be arranged in valve body, and sealing surface of seat uses built-up welding
Or a kind of metal material of welding, on valve body, sealing surface of seat processing difficulties, sealing surface crudy is not easy to ensure, valve base sealing
Face is under high pressure operating mode and easily by medium erosion failure, the shortcomings that seal failure.There is provided a kind of valve seat to be installed on bonnet, flap
It is arranged in valve body, valve seat, flap are easy to process, and valve seat and valve clack sealing surface quality can be guaranteed, valve seal performance
It is good, service life length, suitable on the pipeline of the conveying high-pressure medium such as oil, chemical industry, medium reverse flow can be automatically prevented from
One kind forging high-pressure check valve.
The utility model solves the technical scheme that technical problem uses：The utility model by bonnet, valve body, guide holder,
Valve seat, flap, spring composition, bonnet are provided with inlet opening, and valve body is provided with apopore, and guide holder is provided with discharge orifice, valve body
Built with guide holder, guide holder is equipped with valve seat on bonnet, sealing ring is housed outside valve seat built with flap, spring.
Guide holder center is provided with pilot hole, and pilot hole lower end is provided with step.
Step is provided with valve body, guide holder is spacing in valve body by step.
The utility model has the advantages that：Valve mechanism is simple, valve seat and flap machining are convenient, and sealing surface quality can be with
It is guaranteed, valve seal performance is good, and valve opening and closing is flexible, service life length.

Embodiment
In the accompanying drawings, a kind of forging high-pressure check valve is by bonnet (1), valve body (8), valve seat (2), flap (5), spring (6)
Composition, bonnet (1) are provided with inlet opening (A), and valve body (8) is provided with apopore (B), and guide holder (7) is provided with discharge orifice (F),
For valve body (8) built with guide holder (7), guide holder (7) is equipped with valve seat (2), valve built with flap (5), spring (6) on bonnet (1)
Seat (2) is equipped with sealing ring (3) outside.Guide holder (7) center is provided with pilot hole (C), and pilot hole (C) lower end is provided with step (E), valve body
(8) step (D) is provided with, guide holder (7) is spacing in valve body (8) by step (D).
Operation principle of the present utility model is：When inlet opening, (A) has pressure medium, flap (5) pushing away in pressure medium
Dynamic lower compression spring (6) moves down, and the contact surface of valve seat (2) and flap (5) forms gap, forms medium flow field road junction, works as valve
Valve is fully open when the bottom face of valve (5) reaches step (E) of guide holder (7), and medium is flowed by the inlet opening (A) of bonnet (1)
The discharge orifice (F) flowed to through valve seat and flap formation medium flow field road junction on guide holder (7) is through valve body (8) apopore (B) delivery valve
Body.When inlet opening (A) stops intaking, flap (5) is under the elastic force of spring (6) and backwater effect power, and flap (5) is to moving up
Dynamic, the sealing surface of valve seat (2) and flap (5), which is in close contact, realizes sealing, is automatically prevented from working media reverse flow.
Claims (3)
1. one kind forging high-pressure check valve, is made up of, its feature bonnet (1), valve body (8), valve seat (2), flap (5), spring (6)
It is：Bonnet (1) is provided with inlet opening (A), and valve body (8) is provided with apopore (B), and guide holder (7) is provided with discharge orifice (F), valve
For body (8) built with guide holder (7), guide holder (7) is equipped with valve seat (2), valve seat built with flap (5), spring (6) on bonnet (1)
(2) sealing ring (3) is housed outside.
2. a kind of forging high-pressure check valve according to claim 1, it is characterized in that：Guide holder (7) center is provided with pilot hole
