Abstract

The utility model relates to a four-way valve for a water purifier, which comprises a valve body provided with two valve chambers and four through openings. The upper and the lower valve chambers are communicated through a through opening, and an inlet of the upper valve chamber is connected with the tap water. An outlet of the upper valve chamber and the inlet of the lower valve chamber are connected with a filter element of the water purifier. In addition, a valve handle is arranged in the upper valve chamber, and the valve handle frequently keeps the ejection state by being pushed by a spring device. The valve handle is also controlled by a spinning handle of the outer part of the valve body to close the outlet of the upper valve chamber or the through openings of the upper and the lower valve chambers to alter the flow direction. By means of the structure of the utility model, an outlet pipe of the water purifier can be replaced, and the raw water can be filtrated according the requirement.

Description

Four-way valve for water purifier

The utility model is a kind of innovation of valve body structure, and particularly a kind of confession is home-use, can be with running water tap and water purifier parallel connection, and use the four-way valve structure of same water outlet, replace the water purifier discharge water pipe, and make the difference of Consumer, whether filter with the decision unboiled water according to application target.

Existing water purifier, its mounting type system connects with running water tap, that is, behind the external water purifier of running water tap, the tap water that this water tap flowed out can only be flowed out by water purifier, this installation and drainage pattern, some inconveniences are arranged in the use: the water that (1) self-cleaning hydrophone flows out, its hydraulic pressure flows out for low, so be not suitable as the usefulness of watering flowers, washing thing than water tap; (2) outlet pipe of existing water purifier is very outstanding, and for the space-constrained kitchen, regular meeting hinders one's work.

The purpose of this utility model is to provide a kind of water purifier four-way valve, makes water purifier and the use in parallel of running water tap energy, and uses the outlet pipe that replaces this water purifier.

The technical solution of the utility model is as follows:

Valve body with two valve chambers, four-way mouth, its upper and lower valve chamber respectively has a water outlet and water inlet, and mat one openings connects between upper and lower valve chamber, and upward the water outlet of valve chamber and the valve wall between openings are arcuation again; Last valve chamber and this water outlet, the sidewall that openings is adjacent are provided with a hole, other two blocks that are provided with of hole.Valve rod mechanism system is made of valve rod base, pressure spring and valve rod, and this valve rod base system is hubbed in the valve chamber, and pressure spring and valve rod then are to bear in the valve rod base, the pushing of valve rod and mat pressure spring, and the normal state that ejects of protecting; Be positioned at the valve body outside, and the swing handle that links with valve rod base.

The advantage of the utility model is as follows:

1, easy for installation, original water tap of need not dismantling.

2, easy to use, only need to rotate diverter switch and just former water can be converted to water purification, meet and use the water intaking custom.

3, the water purifier body need not water outlet, reduces volume.

Now cooperate diagram, structure and other feature description of the utility model is as follows:

As shown in Figure 1, the utility model mainly comprises: a valve body 1, with two valve chambers, four-way mouth is established the swing handle 3 that valve rod mechanism 2 in the what valve body 1 and a control valve linkage 2 rotate and is constituted.This valve body 1 is divided into valve chamber 11 and lower valve chamber 16, and last valve chamber 11 has a water inlet 111 and water outlet 113, and also there are a water inlet 162 and a water outlet 164 in lower valve chamber 16, and mat one openings 112 connects between the upper and

lower valve chamber

11,16; The water outlet 113 and the valve wall between the openings 112 of last valve chamber 11 are lonely shape 12, get thereon in order to do the valve rod 23 that makes valve rod mechanism 2 and slide, and should must be homogeneity or heterogeneous thing by orphan's shape valve wall 12 again, also are provided with the through hole 121 of corresponding openings 112 on it; A sidewall 13 adjacent with last valve chamber water outlet 113, openings 112 has a hole 131 that stretches out for valve rod mechanism 2 on it, hole 131 both sides are respectively equipped with orthogonal two blocks 132,133, with the motion of limiting valve linkage 2; Valve body 1 other mat one is prevented the sealing of drain gasket 171 and cover plate 172, makes the worry of ne-leakage.

Valve rod mechanism 2 comprises: a valve rod base 21; One is located at the pressure spring 22 in the valve rod base 21, an and valve rod 23, one recess (showing demonstration among the figure) is arranged at body 211 bottoms of this valve rod base 21, bear for spring 22, valve rod 23, body 211 to both sides be extended with opposing to pole 212,214, front support rod 212 is fixing what cover plate 172, back stay lacks the circle shape for 214 one-tenth, and passes areole 131, and affixed with swing handle 3, these back stay 214 bottoms are provided with a backstop 215 again, in order to do cooperating with sidewall block 132,133.23 pushings that are subjected to spring 22 of valve rod, and the normal state (referring to Fig. 2) that ejects of protecting.

The usage mode of the utility model as shown in Figure 2, the water inlet 111 that should go up valve chamber 11 is to be communicated with water tap, and go up the water outlet 113 of valve chamber 11 and the water inlet 162 of lower valve chamber 16, then be connected with water outlet with the water inlet of filter element of water purifier respectively in (among the figure shown in the imaginary line).When water system confession is from the beginning drunk, then pull swing handle 3, to drive valve rod base back stay 214, make back stay backstop 215 be propped up (shown in solid line among the figure) by block 132, at this moment, valve rod 23 is suitable with through hole 121(openings 112) sealing, fluid Solely can flow to water purifier by last valve chamber outlet 113, behind filter element filtering, flow to lower valve chamber 16 via following valve water inlet 162 again, after 164 outflows of lower valve chamber's water outlet.When the non-confession of tap water is drunk, then pull swing handle 3, to drive valve rod base back stay 214, make back stay backstop 215 be propped up (as shown in phantom in Figure 2) by block 133, at this moment, valve rod 23 is suitable will go up 113 sealings of valve chamber water outlets, and fluid is venerated can be by through hole 121(openings 112) flow to lower valve chamber 16, flow out by water outlet 164 again.

In sum, the utility model water purifier four-way valve, its structure is novel, practical.
