Abstract
The invention relates to a check valve. The check valve comprises a valve body and a valve element installed in the valve body, wherein a supporting spring is arranged on the bottom face of the valve element. The check valve is characterized in that first elastic parts are arranged on the inner wall face of an inlet of the valve body, and baffles are arranged on the portion, where the first elastic parts are opposite to the inlet, of the inner wall face of the valve body. According to the check valve, because the first elastic parts are arranged on the inner wall face of the inlet of the valve body, and the baffles are arranged on the portion, where the first elastic parts are opposite to the inlet, of the inner wall face of the valve body, the upward tension of the valve element is increased, and the problem that the check valve cannot be sealed tightly in the locking process is solved.
Description
Technical field
The present invention relates to a kind of one-way valve.
Background technique
One-way valve is used in pipe container, for limiting pressure or the flow direction, general one-way valve is made up of pipeline, ball sealer, spring and cone structure, when pipeline one end pressure is large, backs down the spheroid at taper hole place, make valve body conducting, when reverse pressure is large, taper hole is sealed by ball, forbids that fluid passes through, complete one-way conduction.Common one-way valve structures is complicated, there is the problem such as wear and leakage and spring failure.
Summary of the invention
For problems of the prior art, the object of the present invention is to provide a kind of technological scheme of one-way valve.
Described a kind of one-way valve, comprises valve body and is installed on the spool in valve body, and this spool bottom surface is provided with supported spring, it is characterized in that described valve body inlet internal face is provided with the first elastic component; The valve interior wall face of described first elastic component and import opposite side is provided with baffle plate.
Described a kind of one-way valve, it is characterized in that the first described elastic component and internal face joint are provided with strut, the masthead end of this strut is in the aperture of inlet's internal face.
Described a kind of one-way valve, is characterized in that described spool sidewall is greater than the distance of baffle sidewall to open centre to the distance of open centre.
Described a kind of one-way valve, is characterized in that the number of the first described elastic component and baffle plate is all more than or equal to two.
Described a kind of one-way valve, is characterized in that the number of described strut is all more than or equal to two.
The present invention is by valve body inlet internal face establishes the first elastic component, baffled on the valve interior wall face of the first elastic component and import opposite side, adds spool pulling force upwards, solves the problem that one-way valve is poorly sealed in locking process.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with Figure of description, the present invention will be further described:
A kind of one-way valve, comprise valve body 1 and be installed on the spool 2 in valve body, this spool bottom surface is provided with supported spring 3, and described valve body inlet internal face is provided with the first elastic component 4, and the valve interior wall face of described first elastic component and import opposite side is provided with baffle plate 5.Owing to also devising elastic component at spool end face, add spool pulling force upwards, solve one-way valve in locking process, the problem that poorly sealed and spool blocks and causes medium to flow backwards.
Above-mentioned first elastic component and internal face joint are provided with strut 6, and the masthead end of this strut is in the aperture 7 of inlet's internal face.Wherein strut is used for fixing elastic component, in order to avoid in compression elastic piece process, elastic component occurs bending and deformation in valve body.This elastic component preferred, baffle plate, supporting element are two, increase stability during locking.And the masthead end of strut is all in the aperture of body top in telescopic process, in order to avoid stretch out outside aperture, affect the installation of other component.
Above-mentioned spool sidewall is greater than the distance of baffle sidewall to open centre to the distance of open centre, coordinates by baffle plate and spool the closedown and unlatching that realize valve body inlet.
When spool is in opening state, spring has thrust upwards to it, and elastic component has pulling force upwards to it; When spool is in closed condition, described thrust and pulling force all approximate zero, and guaranteeing has the fashionable spool of MEDIA FLOW again to open.
