Abstract
The utility model relates to the technical field of valve devices, in particular to a one-way valve.A first elastic piece is arranged on an inner wall surface at an inlet of a valve body of the one-way valve, and a baffle is arranged on the inner wall surface of the valve body on one side, opposite to the inlet, of the first elastic piece, so that the problem of untight locking in a locking process of the one-way valve is solved.
Description
Technical field
The utility model relates to valving technical field, particularly one-way valve.
Background technique
One-way valve, be air-flow can only one direction flow and position control valve that can not 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 one-way valve valve port is opened, and pressurized air flow in valve body from import; In the time of import non-compressed air, under spring force and the effect of valve cavity residual air power; Valve port, in closed condition, makes from valve cavity obstructed to inlet air flow.But because one-way valve is worked and the state of closing and opening continually, after use a period of time, will cause the spool of valve port to block, cause medium flow backwards or can not play good sealing effect.At this time one-way valve needs to change, and has increased cost.
Model utility content
The purpose of this utility model is to provide a kind of one-way valve that has excellent sealing effect.
Realize the technical solution of the utility model 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 the first elastic component side contrary to import is provided with baffle plate.
Described the first elastic component and internal face joint are provided with strut, in the aperture of the masthead end of this strut in inlet's internal face.Wherein strut plays the effect of fixing elastic component.
Described spool sidewall to the distance of open centre is greater than the distance of baffle sidewall to open centre.By baffle plate and coordinating of spool realizing closing and opening valve body inlet.
The number of described the 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 beneficial effects of the utility model are: be provided with the first elastic component by valve body inlet internal face; The valve interior wall face of described the first elastic component side contrary to import is provided with baffle plate.Increase spool pulling force upwards, solved one-way valve in locking process, poorly sealed problem.
Accompanying drawing explanation
By the detailed description below in conjunction with accompanying drawing, the utility model is aforesaid will be become apparent with other object, feature and advantage.
Wherein: Fig. 1 is the utility model structural representation;
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 the first elastic component side contrary to import is provided with baffle plate 5.Owing to also having designed elastic component at spool end face, increased spool pulling force upwards, solved one-way valve in locking process, poorly sealed and spool block and cause medium flow backwards problem.
Described the first elastic component and internal face joint are provided with strut 6, in the aperture 7 of the masthead end of this strut in inlet's internal face.Wherein strut is for fixing elastic component, in order to avoid in compression elastic piece process, elastic component occurs bending and deformation in valve body.Preferred this elastic component, baffle plate, supporting element are two, the stability while increasing locking.And the masthead end of strut all in the aperture in valve body top, in order to avoid stretch out outside aperture, affects the installation of other member in telescopic process.
Described spool sidewall to the distance of open centre is greater than the distance of baffle sidewall to open centre.By baffle plate and coordinating of spool realizing closing and opening valve body inlet.
When spool is during in opening state, spring has thrust upwards to it, and elastic component has pulling force upwards to it; When spool is during in closed condition, described thrust and pulling force all approximate zero, guarantee to have the fashionable spool of MEDIA FLOW again to open.
Claims (5)
1. 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, it is characterized in that, and described valve body inlet internal face is provided with the first elastic component; The valve interior wall face of described the first elastic component side contrary to import is provided with baffle plate.
2. one-way valve according to claim 1, is characterized in that, described the first elastic component and internal face joint are provided with strut, in the aperture of the masthead end of this strut in inlet's internal face.
