Abstract
The utility model discloses a forged anti-collision check valve. The forged anti-collision check valve is characterized by comprising a valve body, a valve cover, springs, a ball, a valve seat, a bushing and a protecting cover. A water inlet and a water outlet parallel to the water inlet are formed in the lower end of the valve body, the valve seat is arranged between the upper portion of the bottom end of the water inlet and the upper portion of the water outlet, the ball is arranged on the valve seat, the bushing is sleeved outside the ball, the protecting cover is arranged at the upper end of the ball, through holes are formed in the protecting cover, and the springs are arranged on the protecting cover. The bushing and the protecting cover are made of non-metal materials. The seal ball does not collide with the metal inner wall of the valve body, a seal face is protected well, and the forged anti-collision check valve is good in seal performance, long in service life, suitable for petroleum pipelines, chemical pipelines and other pipelines conveying high-pressure media, and capable of automatically preventing working media from flowing oppositely.
Description
Technical field
The utility model provides a kind of industries such as oil, chemical industry that are applicable to carry high-pressure medium can stop the safety check of working medium reverse flow automatically.
Technical background
At present, domestic ball check valve generally is made up of major parts such as valve body, valve gap, valve seat, ball sealers, and its seal form belongs to linear sealing, can be when ball is washed open by medium during work in the indoor rotation of ball, with metal valve body wall or the frame of blocking collision, and easily make spheroid damage valve invalidation.
The model utility content
The purpose of this utility model is to overcome existing ball check valve, and ball and metal valve body wall or the metal frame collision spherome surface of blocking damages the shortcoming of valve invalidation during work.Provide a kind of ball not bump with the valve body metal inner surface, good seal performance, long service life is applicable on the pipeline of conveying high-pressure mediums such as oil, chemical industry, can stop a kind of forging anti-collision safety check of working medium reverse flow automatically.
The technological scheme that the utility model technical solution problem adopts is: the utility model is made up of valve body, valve gap, spring, ball, valve seat, lining, protecting cover, valve body lower end is processed with water inlet and parallel with it osculum, between the top of the top of bottom, water inlet and osculum, valve seat is housed, ball is housed on the valve seat, ball is equipped with lining outward, protecting cover is equipped with in the ball upper end, and protecting cover is provided with through hole, and spring is housed on the protecting cover.Lining, protecting cover are made by nonmetallic material.
The utility model has the advantages that: valve mechanism is simple, keying is flexible, ball does not bump good seal performance, long service life with the valve body metal inner surface.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Accompanying drawing is the utility model embodiment's a main sectional view.
1 valve gap, 2 springs, 3 seal rings, 4 linings, 5 protecting covers, 6 valve bodies, 7 balls, 8 valve seats, 9 seal rings among the figure.
Embodiment
In the accompanying drawings, a kind of forging anti-collision safety check is made up of valve body (6), valve gap (1), spring (2), ball (7), valve seat (8), lining (4), protecting cover (5), seal ring (3), valve body (6) lower end is processed with into water (A) hole and parallel with it osculum (B), between the top of the top of bottom, water inlet (A) and osculum (B), valve seat (8) is housed, ball (7) is housed on the valve seat, ball is equipped with lining (4) outward, protecting cover (5) is equipped with in the ball upper end, protecting cover (5) is provided with through hole, and spring (2) is housed on the protecting cover.Lining (4), protecting cover (5) are made by nonmetallic material.
Valve body is by forging molding, and water inlet and water outlet are formed by machining, and valve inlet and outlet are on same axis.Valve body adopts with valve gap and is threaded, and the cooperation place is equipped with seal ring and is realized sealing.During valve working, the import pressure medium promotes ball and moves up, protecting cover pressure spring valve open, and medium is by import process valve seat, lining, water outlet output valve.When system stopped to pressure, ball was at the medium active force of the elastic force level system back pressure of own wt, spring, and ball moves down with valve seat and closely contacts the realization sealing, stops the working medium reverse flow automatically.
Claims (2)
1. one kind is forged the anti-collision safety check, form by valve body (6), valve gap (1), spring (2), ball (7), valve seat (8), lining (4), protecting cover (5), it is characterized in that: valve body (6) lower end is processed with water inlet (A) and parallel with it osculum (B), between the top of the top of bottom, water inlet (A) and osculum (B), valve seat (8) is housed, ball (7) is housed on the valve seat, ball is equipped with lining (4) outward, protecting cover (5) is equipped with in the ball upper end, protecting cover (5) is provided with through hole, and spring (2) is housed on the protecting cover.
2. a kind of forging anti-collision safety check according to claim 1 is characterized in that: lining (4), protecting cover (5) are made by nonmetallic material.
