Annular groove 210, the annular groove 210 and non-return valve body are set on the elastic block water plate 200 of this water-saving check valve
121 inside corner of spoke circle in 100 matches, since elastic block water plate 200 is elastic material, in reverse flow pressure
Under power, 121 inside corner package of spoke circle is formed sealing structure by the groove of elastic block water plate 200.To improve prevention reverse flow
Sealing performance when water.
It please refers to Fig.3 and Fig. 6, the non-return valve seat 300 includes valve seat body 310 and supports column 320, the valve seat sheet
Water Leakage cover 311 is equipped in body 310, and the Water Leakage cover 311 is equipped with throughbore, the column 320 of supporting is vertically installed in institute
State the cover center of Water Leakage cover 311；The valve seat body 310 is adapted with the water outlet of the sleeve 110, described to support column
320 for making the center of the elastic block water plate 200 raise up.
This water-saving check valve structure supports column 320 using non-return valve seat 300, by the central part of elastic block water plate 200
Support fixation upwards so that when water route flow fair current, the border of elastic block water plate 200 is deformed to be led to the flow for forming conducting
Road, when water route flow is flow backwards, elastic block water plate 200 resets and spoke circle 121 is bonded, and with seal path, completes inverse-stopping functions.With
Traditional check (non-return) valve structure compared is simpler, and cost is lower, eliminates the spring in traditional check (non-return) valve, so that assembly is simpler,
The function failure problem that spring failure is brought is eliminated, cost-effective, environmentally protective invention is really achieved.
Further, as shown in figure 4, the pan shape in back-off of elastic block water plate 200, mid-plane is high, and surrounding is low,
To be more adapted with the spoke seat 120, and in water route flow fair current, the border of elastic block water plate 200 can be by more
More water flow pressure, to deformation seal path.
Annular groove 210 is set mutually to be sealed with spoke 122 there are many concrete shape structures of cooperation, such as triangle engaging etc.
Deng.In this embodiment, the corner of 121 inside of the spoke circle is rounded corner (not shown), the cross section of the annular groove 210
(not shown) is in that the arc shape of cooperation is mutually sealed with the rounded corner.The gluing, sealing between circular arc and circular arc is made full use of,
And combine 200 elasticity of of elastic block water plate itself so that the sealing performance of check (non-return) valve is more preferably.
Column 320 and the mutually sliding of elastic block water plate 200 are supported in order to prevent, to influence the normal work of check (non-return) valve,
It further include anti-skid bulge 220, center week of the anti-skid bulge 220 around the elastic block water plate 200 in the present embodiment
To setting, 220 inner rings of the anti-skid bulge are adapted with the column 320 of supporting.
Further, in a tubular form, and the tubulose anti-skid bulge 220 is sheathed on described support to the anti-skid bulge 220
The head of fore-set 320.And the tubulose anti-skid bulge 220 is interference fitted with the head for supporting column 320.It is anti-using tubulose
220 sets of sliding protrusion will support column 320 and elastic block water plate 200 is tightly fixed, and sliding is avoided to cause elastic block water plate 200 inclined
It moves, influences sealing performance.
General water-saving check valve when in use, exists when hydraulic pressure is smaller, the water flow of water-saving check valve is smaller；Work as hydraulic pressure
When increase, the water flow of water-saving check valve synchronizes the case where increasing, i.e., in general, the flow of water is directly proportional to hydraulic pressure.
In order to make check (non-return) valve under different hydraulic pressure, roughly the same water flux density can be kept.In the present embodiment, institute
It states water-saving unit 400 to be set in the non-return valve seat 300, the water-saving unit 400 is used to adjust the water flux density of check (non-return) valve.
Specifically, the water-saving unit 400 includes water-saving piece 410, the border of the water-saving piece 410 is kept off towards the elasticity
200 protrusion of water piece is equipped with elastic outer wall 411, and 410 middle part of the water-saving piece, which is equipped with described in confession, supports the central through hole that column 320 passes through
412,410 border of the water-saving piece and the side wall of the valve seat body 310 form water stream channel 500.
It should be noted that water-saving piece 410 is absolute construction, can as needed disassembled and assembled freely in non-return valve seat 300.
After water enters in non-return valve chamber, water can be along the water stream channel between water-saving piece 410 and non-return valve seat 300
500 toward flowing down, at the same elastic outer wall 411 can hydrosphere there are in water-saving piece 410, thus pressure can act on water-saving piece 410
Elastic outer wall 411 on, with the flow of dampening become larger pressure become larger when, elastic outer wall 411 can be under the active force of hydraulic pressure toward four
Week deformation, can thus change the gap width between water-saving piece 410 and non-return valve seat 300, to realize low hydraulic pressure wide arc gap,
High hydraulic pressure small―gap suture finally obtains the water-saving effect of constant current.
It should be noted that the hardness of 411 material of outer diameter dimension and elastic outer wall by changing water-saving piece 410 can be with
Realize different traffic profiles.
In the present embodiment, the water-saving piece 410 is made of silica gel material.
Further, the height of the elastic outer wall 411 is more than the width of the water stream channel 500.Corresponding, institute
The madial wall for stating valve seat body 310 is equipped with a plurality of vertical raised line 312, and a plurality of vertical raised line 312 is circumferentially distributed in described
On the madial wall of valve seat body 310.It is arranged by the interval of vertical raised line 312 so that check (non-return) valve gathers around that there are one minimum flows
Flux.
It please refers to Fig.1 and Fig. 3 sets to protect the sealed connection of check (non-return) valve and other component at the water inlet end of check (non-return) valve
There is a sealing ring, corresponding, non-return valve outer wall is equipped with an o-ring groove.
Above description is merely a prefered embodiment of the utility model, is not intended to limit the utility model, for
For those skilled in the art, various modifications and changes may be made to the present invention.All spirit and original in the utility model
Within then, any modification, equivalent replacement, improvement and so on should be included within the scope of protection of this utility model.
