Problems solved by technology

[0004] The bushings on the spool of the existing three-position three-way valve are all integrally formed with the spool, resulting in a relatively thick spool, which is easily deformed when the spool moves in the valve body, which leads to disordered water flow channels and affects the cleanliness. If the purification effect of the water purifier is low, it is necessary to replace the entire deformed valve core so as not to affect the purification effect of the water purifier and increase the cost of use.
[0005] Have again, existing spool is made of copper, on the one hand cost is higher, on the other hand copper is easy to corrode, gets rusty, produces copper ion, thereby pollutes water

Embodiment Construction

[0024] The present invention will now be further described in detail in conjunction with the accompanying drawings and embodiments. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present invention in a schematic manner, so it only shows the composition related to the present invention.

[0025] Such as Figure 1 to Figure 4 As shown, a valve core assembly of a three-position three-way valve includes a cylindrical body 10 made of plastic with an axial first water flow channel 50 inside, and a plastic annular ring is detachably sleeved at one end of the body 10 The other end of the main body 10 is integrally formed with an annular plastic raised portion 40, and the main body 10 is provided with a plastic annular second bushing between the first bush 20 and the raised portion 40. 30 , under the wrapping of the valve, a second water flow channel 60 is formed between the second bush 30 and the first bush 20 , and a third water flo...

Abstract

The invention relates to a valve core assembly of a three-position three-way valve. The valve core assembly comprises a cylindrical body internally provided with a first water flow passage in the axial direction; an annular first bush is detachably connected with one end of the body in a sleeving mode; a plurality of slopes for clamping the first bush and preventing the first bush from moving are arranged in the peripheral direction of the end part of the body. The valve core assembly of the three-position three-way valve is made of three detachable parts, comprising the plastic body, the first bush and a second bush, and is easy to assemble, and the thickness of the assembled valve core is not too thick compared with thickness of the traditional integrally molded valve core; the surface of the plastic valve core is smooth, the airtightness between the valve core and a valve is better, the valve core is not easy to deform and cannot cause the staggering of the water flow passages when moving in the valve, and the first plastic bush and second plastic bush are convenient to replace, so the product cost and the use cost are greatly reduced.

Description

technical field [0001] The invention relates to a valve core, in particular to a valve core used for a regulating valve on a water purifier. Background technique [0002] Water is a life resource, and all life activities are inseparable from water. However, with the rapid development of urbanization and industrialization, water resources are constantly polluted. With the improvement of people's awareness of health care, water purifiers are used by more and more people. to ensure the quality of drinking water. The water purifier is to design three channels in the machine, which are forward washing, backwashing and purified water channels. The three go their own way and let the water flow. When ordinary domestic water passes through the forward washing and backwashing channels, it passes The filtering function of the filter element in the machine discharges the sewage and obtains purified water. [0003] As an important part of the water purifier, the valve is directly insta...
