Abstract
The utility model provides a check valve which comprises an inlet end, a valve body and an outlet end. The inlet end is communicated with the valve body which is in a hollow cylindrical shape; the outlet end is in a curved conical shape, one end of the curved conical shape is communicated with the valve body, and the other end of the curved conical shape is closed; and the inlet end, the valve body and the outlet end are all made of elastic materials. By means of the design of the valve body and the outlet end and the materials chosen, the check valve achieves the aim of preventing water from dropping and splattering when a filter element is separated from the head of a water purifier, and meanwhile, can reduce the manufacturing cost.
Description
Technical field
The utility model relates to a kind of Liquid valve, particularly a kind of check valve.
Background technique
Check valve claims again one-way valve.At present the more general one-way valve of seeing is comprised of valve body and spool usually on the market, and spool is by clack valve, valve rod, and backing plate, spring, the structures such as sealing gasket form, its complicated structure, cost is higher.
In the water purifier industry, filter core just need to carry out backwash or replacing after using a period of time, and more during renew cartridge, water remaining in pipeline can flow backwards at every turn, to the floor of family etc. fitting up injury, especially to wood floors.Therefore, a lot of producers can be chosen in the water purifier head one one-way valve is installed, and stop the aqueous reflux of pipeline.Yet, water purifier in use, the filter core body interior is water-filled state, when filter core was backed out from the water purifier head, under the effect of the residual pressure of filter core body interior, the water of filter core body interior also can flow out.Simultaneously, at the water purifier head, one-way valve is installed, the backwash of part filter core just becomes a problem.
Therefore, in order to address the above problem and economical environment-protective and the purpose of controlling cost, ideal situation is, a kind of simply constructed check valve is arranged, can filter core and water purifier head part from the time prevent that water droplet from spilling, and can not affect again the backwash of filter core.
The model utility content
The utility model aims to provide a kind of check valve of novelty, by structural design and the material selection of valve body, reach filter core and water purifier head part from the time prevent from the purpose that water droplet spatters from also reducing simultaneously manufacture cost.
In order to achieve the above object, the utility model provides a kind of check valve, comprises an entry end, valve body and an outlet end, and described entry end is communicated with described valve body; Described valve body is hollow cylindrical; Described outlet end is the curved surface taper shape, and the conical end of described curved surface is communicated with described valve body, and the other end is closed; Described entry end, valve body and outlet end are elastic material.
In the utility model one embodiment, described check valve is formed in one.
In the utility model one embodiment, the diameter of described entry end is less than the diameter of described valve body.
In the utility model one embodiment, described elastic material is for there being commercially available thermoplastic elastomer (TPE) TPE(Thermoplastic Elastomer).
In the utility model, by structural design and the material selection for valve body and outlet end, reached filter core and water purifier head part from the time prevent from the purpose that water droplet spatters from also reducing simultaneously manufacture cost.
Description of drawings
Fig. 1 is the utility model one embodiment's structural representation.
Fig. 2 and Fig. 3 are an embodiment's of the present utility model use state reference maps.
Wherein:
1-check valve, 101-entry end, 102-valve body, 103-outlet end, 2-intake pipe, 3-outlet pipe, 4-filter core body, 401-filter core water intake, 402-filter core water outlet.
Embodiment
Below in conjunction with embodiment, the utility model is described in detail, embodiment is intended to explain and non-limiting the technical solution of the utility model.
See also Fig. 1, shown in Figure 1 is the structural representation of a preferred embodiment of the utility model check valve.
A kind of check valve 1 in the present embodiment comprises an entry end 101, valve body 102 and an outlet end 103.The diameter of described entry end 101 is less than the diameter of described valve body 102, and is communicated with described valve body 102.Described valve body 102 is hollow cylindrical, and described outlet 103 is the curved surface taper shape.The conical end of described curved surface is communicated with described valve body 102, and the other end is closed.Described entry end 101, valve body 102 and outlet end 103 are elastic material.Described elastic material is for there being commercially available thermoplastic elastomer (TPE) TPE.
In the present embodiment, described check valve 1 is formed in one.
See also Fig. 2, Fig. 2 is the use state reference map of the present embodiment.In the present embodiment, described check valve 1 is applied on filter core.As shown in Figure 2, described check valve 1 is placed in respectively water intake 401 and the water outlet 402 of filter core body 4.Because described check valve 1 is elastic material, the end that makes outlet end 103 closure when original state.As shown in Figure 3, after in intake pipe 2 and the outlet pipe 3 described check valves 1 of insertion, strut outlet end 103, realize the water flowing function.After extracting intake pipe 2 and outlet pipe 3, because outlet end 103 is elastic materials, realize closure under the effect of filter core body 4 inner residual pressures, reach leaking outside of prevention filter core body interior water.
The utility model is described by above-mentioned related embodiment, yet above-described embodiment is only for implementing example of the present utility model.Must be pointed out that, published embodiment does not limit scope of the present utility model.On the contrary, being contained in the spirit of claims and modification and impartial setting of scope is included in scope of the present utility model.
