Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out clear,
It is fully described by, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole embodiments.
Based on the embodiment in this utility model, the institute that those of ordinary skill in the art are obtained under not making creative work premise
There are other embodiments, broadly fall into the scope of this utility model protection.
A kind of check valve the most of the present utility model, including valve body 1 and be installed on the spool in valve body 1, valve
Core includes water-logged base 2 and controls the collision mat 5 of water-logged base 2 current break-make, and the middle part of water-logged base 2 is provided with to be run through on water-logged base 2
The through hole 3 at lower two ends, water-logged base 2 circumference is laid with the some inlet openings 4 running through water-logged base about 2 two ends, and collision mat 5 includes
Waterproof gasket 6 and by the waterproof plug 7 upwardly extended in the middle part of waterproof gasket 6, waterproof plug 7 is through through hole 3 and water-logged base 2
Fixing connection, valve body 1 inwall is provided with boss 9, and the upper surface of waterproof gasket 6 presses on the lower surface of boss 9, waterproof gasket 6
The lower surface of upper surface and boss 9 constitute and cut off the blind end of current or water inlet end that the stream that supplies water passes through.When water inlet, waterproof
Pad 6 upper surface pressurized departs from boss 9 lower surface, and check valve is opened, and fluid passes through；When current reflux, waterproof gasket 6
Lower surface pressurized, makes waterproof gasket 6 upper surface contact with the lower surface of boss 9, closed check valve, cuts off current.Collision mat
Sheet 6 flexible, sealing effect is good, improves the overall stability in use of check valve.Valve core structure is simple, and parts are few, group
Dress simplicity, reduces production cost and changes the cost of parts.
The upper surface of waterproof gasket 6 has arc convex, and the lower surface of waterproof gasket 6 has arc groove, beneficially collision mat
The elastic deformation of sheet 6 and reset.The lower surface of water-logged base 2 has the arc-shaped concave suitable with arc convex, boss 9 times
End face has the annular cambered inclined-plane suitable with waterproof gasket 6 outward flange, improves sealing.Waterproof gasket 6 is silica gel.When
So, waterproof gasket 6 can also use other flexible material.The middle part of waterproof plug 7 is provided with collar flange 8, collar flange 8
Lower surface is connected in the upper surface of through hole 3, makes waterproof plug 7 be connected more stable with water-logged base 2.
Valve body 1 inwall is provided with and limits the locating piece 10 that water-logged base 2 moves up, and prevents water-logged base 2 glue from valve body 1.
The water side of valve body 1 is additionally provided with base 11, is additionally provided with and limits the limited post that waterproof gasket 6 moves down in the middle part of base 11
12, base 11 circumference is laid with the some apopores 13 running through base about 11 two ends.This limited post 12 prevents waterproof gasket 6
Pressurized departs from water-logged base 2, improves stability in use.
On inlet opening 4, pressure is provided with current limliting silica gel ring 14, and this current limliting silica gel ring 14 is conducive to controlling rate of flow of fluid.Work as water feeding pressure
Hour, current limliting silica gel ring 14 does not has compressive deformation, plays stop portions flow action；When water feeding pressure is big, current limliting silica gel ring
14 compressive deformations, blocking portion inlet opening 4, play control flow effect.It is arranged with water proof ring 15 outside valve body 1, prevents fluid
Flow out from valve body 1 outer wall or flow into, preventing seepage.
Operation principle: during water inlet, current pass inlet opening, and waterproof gasket 6 pressurized deforms downwards so that waterproof gasket 6 upper end
Face pressurized departs from boss 9 lower surface, and check valve is opened, and current flow out from apopore 13；If hydraulic pressure is excessive, limited post 12
Press on the lower surface of waterproof gasket 6, prevent waterproof gasket 6 from continuing downwards and deform or depart from water-logged base 2；When reflowed, anti-
Water cushion sheet 6 lower surface pressurized resets, and makes waterproof gasket 6 upper surface contact with the lower surface of boss 9, and closed check valve prevents
Current reflux.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all new in this practicality
Within the spirit of type and principle, any modification, equivalent substitution and improvement etc. made, should be included in protection of the present utility model
Within the scope of.
