Abstract
The invention discloses a check valve, which comprises a valve body, a flowing water channel, a valve core, an elastic element, a gasket and a water passing cover, wherein the valve core comprises a guidepost, the valve body is provided with a guide groove for containing the guidepost, the valve core can telescopically move in the guide groove of the valve body, the water passing cover is installed at the end part of the valve body, and the gasket is arranged at the joint of the valve body and valve core as well as the joint of the valve body and water passing cover to realizing the sealing effect. The check valve solves the technical problem that dirty water backflow caused by negative pressure is easily occurred in daily life during a user uses a nozzle to take a shower.
Description
Technical field
The present invention relates to a kind of check valve, particularly relate to a kind of check valve be used on sanitaryware.
Background technique
In daily life process, a lot of user is after using shower facilities, shower nozzle can be placed on conveniently in the container be filled with water, when using next time, open the switch of shower nozzle, can produce certain negative pressure between shower nozzle and the container be filled with water, this negative pressure can cause a resorption of gas in shower nozzle, so just likely the addle of the container be filled with water can be sucked back, in shower process, bring inconvenience to user.
Summary of the invention
The invention provides a kind of check valve, carry out at use shower nozzle the technical problem that in the process of shower, incidental addle refluxes because of negative pressure to solve user in daily life.In order to solve above technical problem, the technological scheme that the present invention takes is:
A kind of check valve is provided, comprise a valve body, be positioned at the flowing water water route of valve body, spool, elastic element, packing ring and excessively water cover, wherein said spool comprises a directional post, described valve body is provided with the guiding groove holding described directional post, and described spool can telescopically move in described valve body guiding groove, described water cover is excessively arranged on the end of valve body, and the joint that described packing ring is arranged on described valve body and spool and valve body and mistake water cover seals.
Described elastic element is socketed that on described directional post and one end of described elastic element is connected to described spool, the other end is connected to and describedly crosses water cover.
When described flowing water is flowed out from described mistake water cover by the flowing water water route being positioned at described valve body, the active force that described spool can overcome elastic element under the impact force action of described flowing water moves down along described valve body guiding groove.
Described elastic element is Compress Spring.
Described valve body is provided with annular groove, and described mistake on water cover is provided with the annular protrusion coordinated with described annular groove.
After employing technique scheme, because check valve of the present invention takes the structure of one-way flow, when current are from when crossing in water cover inflow check valve, the elastic force that elastic element gives spool can make to combine closely between spool and valve body, current can be made like this to penetrate spool, when flowing water flows in check valve from water pipe, flowing water can give spool impact force, the elastic force that this impact force can force spool to overcome elastic element moves down along valve body guiding groove, at this moment flowing water can flow out from crossing water cover through spool, the one-way conduction effect of this check valve avoids addle and flows into water pipe from crossing water cover above, user can be allowed to use the shower nozzle with this check valve to carry out shower at leisure.
Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the sectional view of check valve of the present invention;
Fig. 2 is the partial enlarged view of A in Fig. 1;
Fig. 3 is the decomposition view of check valve of the present invention;
Embodiment
For making the object of the embodiment of the present invention, technological scheme and advantage clearly, below in conjunction with the accompanying drawing in the embodiment of the present invention, technological scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
As Fig. 1, shown in Fig. 2 and Fig. 3, check valve 10 of the present invention comprises: a valve body 1, be positioned at the flowing water water route 6 of valve body 1, spool 3, elastic element 4, packing ring 2 and excessively water cover 5, wherein spool 3 comprises a directional post 3a, valve body 1 is provided with the guiding groove 1a holding directional post 3a, elastic element 4 is socketed on directional post 3a, and one end is connected to spool 3, the other end was connected to water cover 5, spool 3 can be telescopically mobile in valve body 1, cross the end that water cover 5 is arranged on valve body 1, packing ring 2 is arranged on described valve body 1 and spool 3 and valve body 1 and seals with the joint crossing water cover 5, wherein valve body 1 is provided with annular groove 1b, cross annular protrusion 5b water cover 5 being provided with and coordinating with annular groove 1b, in embodiments of the present invention, elastic element 4 all replaces with Compress Spring.
Below with regard to composition graphs 1, Fig. 2 and Fig. 3 elaborates a working principle of following check valve of the present invention: because check valve 10 of the present invention takes the structure of one-way flow, when current are from when water cover 5 flows in check valve 10 excessively, the elastic force that elastic element 4 gives spool 3 can make to combine closely between spool 3 and valve body 1, current can be made like this cannot to penetrate spool 3 by flowing water water route 6, when user opens shower switch, flowing water can flow into from water pipe the flowing water water route 6 being positioned at check valve 10, at this moment flowing water can give spool 3 one impact forces, the elastic force that this impact force can force spool 3 to overcome elastic element 4 moves down along valve body guiding groove 1a, at this moment flowing water can flow out from crossing water cover 5 through flowing water water route 6 through spool 3, when user closes shower switch, spool 3 can move up along valve body guiding groove 1a under the elastic restoring force effect of elastic element 4, thus and formed between valve body 1 and be tightly connected.The one-way conduction effect of this check valve 10 avoids addle and flows into water pipe from crossing water cover 5 above, and user can be allowed to use the shower nozzle with this check valve 10 to carry out shower at leisure.
Last it is noted that above embodiment is only in order to illustrate technological scheme of the present invention, be not intended to limit; Although with reference to previous embodiment to invention has been detailed description, those of ordinary skill in the art is to be understood that: its in specification still can be modified to the technological scheme described in foregoing embodiments, or equivalent replacement is carried out to wherein portion of techniques feature, does not make the essence of appropriate technical solution depart from the spirit and scope of various embodiments of the present invention technological scheme.
