Abstract
The invention relates to the technical field of valve devices, in particular to a one-way valve. A first elastic part is arranged on the inner wall face of an inlet of a valve body of the one-way valve, and a baffle is arranged on one side, arranged on the inner wall face of the valve body, and opposite to the inlet, of the first elastic part. The problem that in the locking process of the one-way valve, locking is not tight is solved.
Description
Technical field
The present invention relates to valving technical field, particularly one-way valve.
Background technique
One-way valve is that air-flow can only direction flowing and can not the position control valve of reverse flow.Its working principle is the same with hydraulically-controlled one-way valve.Pressurized air enters from import, overcomes spring force and frictional force makes one-way valve valve port open, and pressurized air flow in valve body from import; When import non-compressed air, under spring force and the effect of valve cavity residual air power; Valve port is in closed condition, makes from valve cavity obstructed to inlet air flow.But because one-way valve works and the state of closing and opening continually, after using a period of time, the spool of valve port will be caused to block, cause medium flow backwards or good sealing effect can not be played.At this time one-way valve needs to change, and adds cost.
Summary of the invention
The object of this invention is to provide a kind of one-way valve having excellent sealing effect.
Realize technological scheme of the present invention as follows:
One-way valve, described individual event valve comprises valve body, and is installed on the spool in valve body, and this spool bottom surface is provided with supported spring, and 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 first elastic component and internal face joint are provided with strut, and the masthead end of this strut is in the aperture of inlet's internal face.Wherein strut plays the effect of fixing elastic component.
Described spool sidewall is greater than the distance of baffle sidewall to open centre to the distance of open centre.The closedown and unlatching that realize valve body inlet is coordinated by baffle plate and spool.
The number of described first elastic component and baffle plate is all more than or equal to two.Make sealing effect better.
The number of described strut is all more than or equal to two.Make sealing effect better.
The invention has the beneficial effects as follows: be provided with the first elastic component by valve body inlet internal face; The valve interior wall face of described first elastic component and import opposite side is provided with baffle plate.Add spool pulling force upwards, solve one-way valve in locking process, poorly sealed problem.
Accompanying drawing explanation
By the detailed description below in conjunction with accompanying drawing, aforesaid and other object, the feature and advantage of the present invention will become apparent.
Wherein: Fig. 1 is structural representation of the present invention;
In accompanying drawing, 1 is valve body, and 2 is spool, and 3 is supported spring, and 4 is the first elastic component, and 5 is baffle plate, and 6 is strut, and 7 is aperture.
Embodiment
Shown in Figure 1, one-way valve, described individual event valve comprises valve body 1, and is installed on the spool 2 in valve body, and 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; 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.
Described 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.
Described spool sidewall is greater than the distance of baffle sidewall to open centre to the distance of open centre.The closedown and unlatching that realize valve body inlet is coordinated by baffle plate and spool.
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.
