Abstract
The utility model discloses a lateral-through type check valve, which comprises a valve body. A water inlet and a water outlet are formed on the side edge of the valve body. The water inlet is formed at the bottom of the valve body, and the water outlet is formed on the top of the valve body. A passage is formed between the valve body and each of the water inlet and the water outlet. A tapered opening is formed between the inside of the valve body and the water outlet. A sealing ball is arranged at the tapered opening. A pressure spring is pressed against the lower end of the sealing ball. The lower end of the pressure spring is pressed against a sealing cap which is connected with the valve body in a sealed way. A pushrod is connected to the top of the valve body in a sliding way, penetrates through the valve body, and is pressed against the upper end of the sealing ball. A top cap is arranged on the top of the valve body. A first sealing ring is arranged in the top cap, and the push rod and the valve body are matched in a sealed way through the first sealing ring. The lateral-through type check valve is rational in structural design, low in cost, continuous, reliable, long in service life and particularly applicable to a tap water pipeline, and has good using effects, and water flow can be circulated in different directions within a certain range.
Description
Technical field
The utility model relates to a kind of one-way valve, the especially a kind of side general formula one-way valve that can realize water route side direction conducting after being applied by external force.
Background technique
At present in industrial and mining enterprise's production application, the one-way valve that designs for hydraulic pressure or Pneumatic Transmission all is a straight-through type generally, and is transplanted to the household tap water conducting and uses and have many inappropriate factors to exist.Can be applicable to and be used in family or the interior decoration realize that the unidirectional automatic valve of tap water conducting specific (special) requirements is short of very much.
Summary of the invention
The utility model will solve the shortcoming of above-mentioned existing technology, provides a kind of and whether applies the side general formula one-way valve of realizing controlling operation by external force, and when there not being external force to do the time spent, current end, and the connection of suitable different amount pipeline.
The utility model solves the technological scheme that its technical problem adopts: this side general formula one-way valve; Comprise valve body, the side of valve body is provided with into water interface, water outlet interface, and the water inlet interface is positioned at the bottom of valve body; The water outlet interface is positioned at the top of valve body; Form a passage between water inlet interface, water outlet interface and the valve body, be provided with taper mouth in the valve body and between the water outlet interface, the taper mouth place is provided with ball sealer; The lower end roof pressure of ball sealer has holddown spring, the lower end roof pressure of holddown spring with sealing cover that valve seal is connected on; The top of valve body slidely connects catch bar, and this catch bar passes valve body and withstands on the upper end of ball sealer, is provided with top cover on the top of valve body, is provided with the seal ring one that catch bar is cooperated with valve seal in the top cover.Through pressing down catch bar, catch bar promotes ball sealer and moves down, and opens the passage in the valve body; Make the into passage circulation of water interface and water outlet interface; Remove the external force on the catch bar, then promote to move on the ball sealer, make the into passageway shuts off of water interface and water outlet interface through holddown spring.
Sealing cover is threaded in the bottom of valve body, and between sealing cover and valve body, is provided with seal ring two.Guarantee being sealed and matched between sealing cover and the valve body like this.
The effect that the utility model is useful is: the utility model project organization is reasonable, using effect good, cost is low, continuously reliable, long service life, make current within the specific limits different direction realize through-flowly down, be particularly suitable for the application on the tap water pipe line.

Description of reference numerals: valve body 1, taper mouth 1-1, water inlet interface 2, water outlet interface 3, catch bar 4, top cover 5, seal ring 1, ball sealer 7, holddown spring 8, sealing cover 9, seal ring 2 10.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further:
With reference to accompanying drawing: this side general formula one-way valve; Comprise valve body 1, the side of valve body 1 is provided with into water interface 2, water outlet interface 3, and water inlet interface 2 is positioned at the bottom of valve body 1; Water outlet interface 3 is positioned at the top of valve body 1; Form a passage between water inlet interface 2, water outlet interface 3 and the valve body 1, be provided with taper mouth 1-1 in the valve body 1 and between the water outlet interface 2, taper mouth 1-1 place is provided with ball sealer 7; The lower end roof pressure of ball sealer 7 has holddown spring 8, and the lower end roof pressure of holddown spring 8 is on the sealing cover 9 that is tightly connected with valve body 1; The top of valve body 1 slidely connects catch bar 4, and this catch bar 4 passes valve body and withstands on the upper end of ball sealer 7, is provided with top cover 5 on the top of valve body 1, is provided with the seal ring 1 that catch bar 4 and valve body 1 are sealed and matched in the top cover 5.Sealing cover 9 is threaded in the bottom of valve body 1, and between sealing cover 9 and valve body 1, is provided with seal ring 2 10.
Be provided with a catch bar 4 in the upper-end surface of valve body 1, this catch bar 4 is pressed to ball sealer 7 through the hole on the top cover 5.Under the effect of external force, this catch bar 4 can be depressed ball sealer 7, Open valve; Be close to the taper mouth 1-1 on valve body 1 inner passage through ball sealer 7, realize closing of valve.Be provided with a sealing cover 9 in the lower end surface of valve 1; A holddown spring 8 is housed above that, and sealing cover 9 compresses seal ring 2 10, withstands ball sealer 7 simultaneously; Can be after the external force on the catch bar 4 be removed; Pretightening force through holddown spring 8 realizes that closing automatically of this valve resets (ball sealer 7 is close to taper mouth 1-1 and is realized closing of valve), and the design tries hard to keep outside and realizes when holding that the water route connects, but after external force is removed the fast shut-off water route.
Though the utility model is through illustrating and describe with reference to preferred embodiment,, those skilled in the art should understand, and in the scope of claims, can do the various variation on form and the details.
