Description
Technical field
It the utility model is related to valve field, more particularly to a kind of check valve.
Background technology
Check valve refers to flow in itself by medium and automatic open and close valve element, and only allows fluid to flow in one direction
Valve, check valve plays the role of important in the pipeline for preventing medium from flowing backwards, and existing check valve uncomfortable can not throttle
Amount, in pumped (conveying) medium, because the impulsive force of medium can reduce the sealing of check valve.Therefore, how check valve is enable
Flow-rate adjustment is carried out, impulsive force during check valve pumped (conveying) medium is reduced, is always the problem that the whole society faces.
Utility model content
The purpose of this utility model is to provide a kind of check valve, to solve above-mentioned technical problem.
The utility model uses following technical scheme to achieve the above object：
A kind of check valve, including valve body, flow distribution plate, valve inlet, valve export, the valve body middle part is hollow design,
Valve inlet, valve export are offered successively along the direction of valve body, and valve inlet is corresponding with valve export, close to valve inlet
Valve body in be welded with flow distribution plate, valve inlet is divided into upper, middle, and lower part, the size phase of three parts branch pipe by flow distribution plate
Together, the outlet of the branch pipe is connected with valve export, and it is in funnel type to export, and the exit of upper and lower two parts branch pipe is welded with
Spring, the free end of spring are welded with rubber stopper and blocked up, and axis connection baffle plate, the connection of baffle plate are provided with the branch pipe of the center section
Stopper is welded with the vertical direction of axle, the vertical direction of stopper is provided with the screw rod of threaded connection, and screw rod runs through valve
Body.
Preferably, stifled tapered of the rubber stopper, and the size of the stifled largest face of rubber stopper is more than the size of outlet.
Preferably, permanent magnet is inlaid with the stopper, baffle plate is 304 stainless steels.
Compared with prior art, the utility model has advantages below：The utility model is simple in construction, reasonable in design；Point
Flowing plate can shunt to medium, reduce impulsive force of the medium to check valve；When check valve needs to carry out Flow-rate adjustment, energy
Enough by the aperture of screw rod controllable register, the regulation of flow is realized by the aperture of controllable register；Rubber stopper it is stifled from figure
Denaturation extends service life, and sealing improves, and preferably promotes the use of.
Brief description of the drawings
Fig. 1 is the utility model check valve schematic diagram.
Fig. 2 is the upper and lower part branched pipe schematic diagram of the utility model check valve.
Fig. 3 is the center section branch pipe schematic diagram of the utility model check valve.
In figure：1st, branch pipe, 2, flow distribution plate, 3, valve body, 4, valve outlet, 5, spring, 6, rubber stopper block up, 7, outlet, 8, spiral shell
Bar, 9, stopper, 10, baffle plate, 11, valve body import.
Embodiment
The utility model is further elaborated with specific embodiment below in conjunction with the accompanying drawings.
As Figure 1-3, a kind of check valve, including valve body 3, flow distribution plate 2, valve inlet 11, valve export 4, the valve
The middle part of body 3 is hollow design, and valve inlet 11, valve export 4, valve inlet 11 and valve are offered successively along the direction of valve body 3
Door outlet 4 is corresponding, and flow distribution plate 2 is welded with the valve body 3 of valve inlet 11, and flow distribution plate can shunt to medium,
Impulsive force of the medium to check valve is reduced, valve inlet 11 is divided into upper, middle, and lower part, three parts branch pipe by flow distribution plate 2
1 size is identical, and the outlet 7 of the branch pipe 1 connects with valve export 4, and it is in funnel type to export 7, upper and lower two parts branch pipe 1
Outlet 7 at be welded with spring 5, spring is made up of PVC material, and the free end of spring 5 is welded with rubber stopper stifled 6, the centre
Axis connection baffle plate 10 is provided with partial branch pipe 1, stopper 9, stopper are welded with the vertical direction of the connecting shaft of baffle plate 10
Permanent magnet is inside inlaid with, baffle plate is 304 stainless steels, and the vertical direction of stopper 9 is provided with the screw rod 8 of threaded connection, and
Screw rod 8 runs through valve body 3.
Utility model works principle：When medium by valve body import 11 enter valve body 3 in, work of the medium in flow distribution plate 2
With lower shunting, reflux plate 2 can reduce impulsive force of the medium to check valve, when needing to carry out Flow-rate adjustment, can pass through tune
The height for saving screw rod 8 carries out Flow-rate adjustment, when medium enters upper and lower two parts branch pipe 1, medium energy to the aperture of baffle plate 10
Enough make spring 5 that rubber stopper is blocked up into 6 ejections, after the completion of medium conveying, rubber stopper can be blocked up 6 and taken back the progress of outlet 7 by spring 5
Closure, the resistance of medium itself and the attraction of stopper 9 can make baffle plate 10 block the branch pipe of center section.
Described above is the utility model preferred embodiment, for the ordinary skill in the art, according to this reality
With new teaching, in the case where not departing from principle of the present utility model and spirit, the change that is carried out to embodiment, repair
Change, replace and modification is still fallen within the scope of protection of the utility model.
