Example Embodiment

[0020] The present invention will now be described in further detail with reference to the drawings and embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the constitutions related to the present invention.

[0021] Such as Figure 1 to Figure 3 As shown, a valve core of a three-position three-way valve includes a cylindrical body 10 made of plastic with an axial first water flow channel 11 inside, and a plastic annular bushing is detachably provided on the body 10 20. The bushing 20 is sleeved on the body 10, can rotate relative to the body 10 in the circumferential direction, and does not slide relative to the body 10 in the axial direction. Under the valve wrapping, the bushing 20 and one end of the body 10 form a second A third water flow channel 13 is formed between the water flow channel 12 and the other end of the body 10. When the valve core moves...

Abstract

The invention relates to a valve core of a three-position three-way valve. The valve core comprises a cylindrical body internally provided with a first water flow passage in the axial direction; an annular bush rotatably sleeves the body; a second water flow passage is formed between the bush and one end of the body under the wrapping of a valve; a third water flow passage is formed between the bush and the other end of the body. The bush can detachably sleeve the body of the valve core and the bush can rotate relative to the body without sliding, so the valve core has the advantage that the thickness of the plastic valve core can be controlled compared with the mode that the bush is integrally molded on the body of the valve core, the surface of the plastic valve core is smooth, the airtightness between the valve core and the valve is better, the valve core is not easy to deform and can not cause the staggering of the water flow passages when moving in the valve, the plastic bush can be replaced and 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 effect 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 install...
