Abstract
The utility model discloses a swing check valve, which comprises a valve body, a valve clack and a valve cover, wherein an installation part is arranged in the valve body, and a fork-shaped piece is installed on the installation part and is fixed by screws; the fork-shaped piece is hinged with a swing arm, and the swing arm rotates around a hinged point relatively; the valve clack is fixed on the swing arm through a valve clack cover; the free end of the swing arm is bent and extends outwards to form a limiting rod; and a limiting block is arranged on the inner wall of the valve body and opposite to the limiting rod. The problem of current valve body leak and current valve body maintenance inconvenience, life are short is solved.
Description
Technical field
The utility model relates to valve technology field, and more particularly, it relates to a kind of Swing check valve.
Background technique
Safety check is for preventing the refluence of pipeline medium.When medium forward flow in pipeline, the flap of safety check is automatically opened under the effect of medium power, and when medium reverse flow in pipeline, flap is automatically closed under the effect of medium power.Swing check valve is a kind of the most frequently used safety check.
Swing check valve of the prior art, comprises valve body, flap, rocking arm, valve shaft, pad and plug screw.Flap is arranged on rocking arm, and rocking arm is suspended on valve shaft, and in order to install valve shaft, holes drilled through on valve body usually, is arranged on valve shaft after on valve body, adopts pad and plug screw to seal at the axis hole two ends of valve body.Because this structural design needs holes drilled through on valve body, although through hole adopts pad and plug screw to seal, still there is the hidden danger that valve body leaks.
Model utility content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of Swing check valve, solve problem that existing valve body leaks and existing valve body inconvenient maintenance, working life short problem.
For achieving the above object, the utility model provides following technological scheme: Swing check valve, comprises valve body, flap and valve gap, it is characterized in that, is provided with assembly department in described valve body, described assembly department is provided with Y-piece and is screwed; Described Y-piece is hinged with swing arm and this swing arm relatively rotates around articulating point; Described flap is fixed in described swing arm by valve clack cover; On the free end of described swing arm, bending is outward extended with position-limited lever; Be positioned at the inwall of valve body and the position relative with position-limited lever is being provided with limiting stopper.
Swing arm of the present utility model is hinged on the assembly department in valve body; Punching on valve body is not needed to install; Thus the problem that solution valve body is revealed because punching produces gap; Limiting stopper can adopt elastic material, and when flap is drawn back by water slug, position-limited lever bumps against on elastic spacing block, can play buffer function, reduces the injury to valve body.
Preferably, described flap is provided with joint, described joint has radially outstanding protuberance; Described swing arm offers attachment hole; Described joint and described attachment hole interference fit.
Preferably, described valve body and valve gap are bolted, and are provided with sealing gasket between the two.
Preferably, the top of described valve gap is bolted with suspension ring.
The beneficial effect that the utility model possesses: this maintenance of valve facilitates, there is not leakage hidden danger; Long perfomance life.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is partial enlargement structural representation of the present utility model.
Embodiment
With reference to Fig. 1-2, the utility model Swing check valve embodiment is described further.
Swing check valve, comprises valve body 1, flap 2 and valve gap 4.Be provided with assembly department 5 in valve body 1, assembly department 5 is to projecting inward step from valve body 1 inwall.Assembly department 5 has a through hole, Y-piece 6 is screwed on assembly department 5.Y-piece 6 is hinged with swing arm 7 and this swing arm 7 relatively rotates around articulating point.Swing arm 7 has an attachment hole 72; Flap 2 is provided with joint 21, the shape of joint 21 is cylindrical.This joint 21 has radially outstanding protuberance 22.Joint 21 is inserted in attachment hole 72 and attachment hole 72 interference fit.Joint 21 has hole, and the end that flap 2 covers is inserted in this hole, and is screwed.The other end that flap 2 covers is greater than hole, and flap 2 is fixed in described swing arm 7 by flap 2 lid.
On the free end 71 of swing arm 7, bending is outward extended with position-limited lever 9; Be positioned at the inwall of valve body 1 and the position relative with position-limited lever 9 is being provided with limiting stopper 10.Limiting stopper 10 can adopt elastic material, and when flap 2 is drawn back by water slug, position-limited lever 9 bumps against on elastic spacing block 10, can play buffer function, reduces the injury to valve body 1.
Valve body 1 and valve gap 4 are bolted, and are provided with sealing gasket 11 between the two.The top of valve gap 4 is bolted with suspension ring 12.
The above is only preferred implementation of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technological schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
