Description

A kind of forging high-pressure check valve
Technical field
Being suitable for the industries conveying high-pressure medium such as oil, chemical industry the present invention provides one kind, to be automatically prevented from medium reversed The forging high-pressure check valve of flowing.
Technical background
Currently, domestic high-pressure check valve is generally made of major parts such as valve body, valve deck, 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, processing quality is not easy to ensure, under high pressure operating mode and easily by medium erosion failure, seal failure.
Invention content
It is an object of the invention to overcome existing check valve receptacle to be arranged in valve body, sealing surface of seat using built-up welding or A kind of metal material is welded on valve body, sealing surface of seat processing difficulties, sealing surface processing quality 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.It provides a kind of valve seat to be installed on valve deck, valve Valve is arranged in valve body, and valve seat, flap are easy to process, and valve seat and valve clack sealing surface quality can be guaranteed, valve tightness Can be good, service life is long, is suitable on the pipelines of conveying high-pressures medium such as oil, chemical industry, can be automatically prevented from medium reverse flow A kind of forging high-pressure check valve.
The present invention solve technical problem the technical solution adopted is that:The present invention is by valve deck, valve body, guide holder, valve seat, valve Valve, spring composition, valve deck are equipped with inlet opening, and valve body is equipped with apopore, and guide holder is equipped with discharge orifice, is equipped in valve body Guide holder, guide holder is interior to be equipped with flap, spring, and valve seat is housed on valve deck, sealing ring is housed outside valve seat.
Guide holder center is equipped with pilot hole, and pilot hole lower end is equipped with step.
Step is equipped in valve body, guide holder is limited by step in valve body.
It is an advantage of the invention that:Valve mechanism is simple, valve seat and flap mechanical processing are convenient, and sealing surface quality can obtain To guarantee, valve seal performance is good, and valve opening and closing is flexible, service life is long.
Description of the drawings
Present invention will be further explained below with reference to the attached drawings and examples.
Fig. 1 is the main sectional view of the embodiment of the present invention;
Fig. 2 is the A-A sectional views of Fig. 1.
1 valve deck, 2 valve seats, 3 sealing rings, 4 sealing rings, 5 flaps, 6 springs, 7 guide holders, 8 valve bodies, the water inlet of A valve decks in figure Hole, B valve bodies apopore, C pilot holes, D steps, E steps, the discharge orifices F.
Specific implementation mode
In the accompanying drawings, a kind of forging high-pressure check valve is by valve deck (1), valve body (8), valve seat (2), flap (5), spring (6) Composition, valve deck (1) are equipped with inlet opening (A), and valve body (8) is equipped with apopore (B), and guide holder (7) is equipped with discharge orifice (F), Guide holder (7) is housed in valve body (8), flap (5), spring (6) are housed in guide holder (7), valve seat (2) is housed on valve deck (1), Valve seat (2) is equipped with sealing ring (3) outside.Guide holder (7) center is equipped with pilot hole (C), and the lower end pilot hole (C) is equipped with step (E), Step (D) is equipped in valve body (8), guide holder (7) is limited by step (D) in valve body (8).
The present invention operation principle be:When inlet opening, (A) has pressure medium, flap (5) is under the promotion of pressure medium Compressed spring (6) moves down, and valve seat (2) and the contact surface of flap (5) form gap, form medium flow field road junction, work as flap (5) valve is fully open when bottom face reaches step (E) of guide holder (7), and medium is flowed through by the inlet opening (A) of valve deck (1) Valve seat forms medium flow field road junction with flap and flows to the discharge orifice (F) on guide holder (7) through valve body (8) apopore (B) delivery valve Body.
When inlet opening (A) stop intake when, flap (5) under the elastic force of spring (6) and backwater effect power, flap (5) to The sealing surface of upper movement, valve seat (2) and flap (5), which is in close contact, realizes sealing, is automatically prevented from working media reverse flow.
