Description
Technical field
Check-valves claims again check valve or non-return valve, and its effect is to prevent that the medium in pipeline from flowing backwards, and the bottom valve that pump sump closes also belongs to check-valves class. Check-valves is that a kind of opening and closing element is opened voluntarily or closes by media flow and strength, with the valve that prevents that medium from flowing backwards, belongs to automatic valve class, is mainly used on the pipeline of medium one-way flow, only allows medium to flow to a direction, to try to avert accidents.
Check-valves kind of the prior art is a lot, but the non-return transmission efficiency of check-valves and sealing one are check-valves study hotspot and difficult point.
Background technology
The utility model relates to a kind of valve, specifically a kind of through type high leakproofness check-valves.
Utility model content
The purpose of this utility model is the defect for prior art, and a kind of through type high leakproofness check-valves is provided, and can only seal rapidly and sensitively withdrawing fluid, and good airproof performance, and fluid is easy to leak not.
The utility model is achieved by the following technical solutions:
A kind of through type high leakproofness check-valves, comprise coupling body and nipple body, wherein, be provided with intake tunnel and the first working of plastics in described coupling body, described intake tunnel and the first working of plastics coaxially arrange, described the first working of plastics is by body and pullover composition, described pullover be umbrella, described pullover top is arranged in intake tunnel through body, and pullover both sides are connected with body, described pullover top is provided with through hole, and described body end face is connected with intake tunnel;
In described the first working of plastics, be provided with the second working of plastics, described the second working of plastics is made up of a umbrella body and connecting rod, a described umbrella body has plush copper, described plush copper is positioned at a umbrella body center, a described umbrella body is provided with some grooves, described some grooves one end is connected with plush copper, and within one week, arrange around plush copper, the body of a described umbrella body two ends and the first working of plastics is affixed, described connecting rod one end is connected with plush copper, the other end is arranged in the pullover through hole of the first working of plastics, described connecting rod is provided with spring outward, described spring one end is connected with pullover, the other end is connected with a umbrella body,
Described nipple body one end is as for coupling body inside, and is connected with coupling body, between described nipple body and the first working of plastics, is provided with sealing gasket, in described nipple body, is provided with exhalant canal, and described exhalant canal and intake tunnel are point-blank.
Above-mentioned a kind of through type high leakproofness check-valves, wherein, described exhalant canal has connector, and the body of described connector and the first working of plastics is oppositely arranged, and the internal diameter of described connector is d1, and the internal diameter of described body is d2, described d1 < d2.
The beneficial effects of the utility model are:
Working method of the present utility model is: the utility model is arranged on fluid circuit, in the time that fluid passes into intake tunnel, fluid pressure makes the connecting rod of the second working of plastics be ejected by the first working of plastics, spring stretches, and fluid can flow out from the flow through groove of body inside, a umbrella body and exhalant canal of intake tunnel; In the time that fluid pressure stops promoting, spring reset, drives connecting rod as for blocking through hole in the first working of plastics, prevents that fluid from refluxing.
The utility model is blocked through hole with connecting rod, and with sealing gasket fitted seal, makes the utility model can only seal rapidly and sensitively withdrawing fluid, and good airproof performance, and fluid is easy to leak not.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the utility model umbrella body top view.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described further.
