Detailed Description

The technical solution of the present invention will be further explained with reference to the accompanying drawings.

Referring to fig. 1-4, the electromagnetic valve includes a valve body 1, a first main body 2 and a second main body 3 respectively communicated with the valve body 1, a water inlet chamber disposed in the first main body 2, and a water outlet chamber disposed in the second main body 3. The valve body 1 is used for controlling the on-off between the water inlet cavity and the water outlet cavity.

The electromagnetic valve further comprises the following components which are sequentially arranged along the water inlet direction: the water inlet pipe 4 is communicated with the first main body 2, the fixing piece 5 is arranged in the water inlet cavity, and the elastic diaphragm 6 is arranged in the water inlet cavity.

The water inlet pipe 4 comprises a first pipe body 41 which can rotate around the axis line direction of the water inlet pipe and is arranged in the water inlet cavity in a penetrating mode, one end, extending into the water inlet cavity, of the first pipe body 41 is abutted to the fixing piece 5, the other end of the first pipe body 41 penetrates out of the water inlet cavity, and the water inlet pipe 4 further comprises a second pipe body 42 which is located outside the water inlet cavity and communicated with the first pipe body 41. Through this setting, inlet tube 4 can avoid extrudeing elastic diaphragm 6 and lead to its deformation to damage when rotating the regulation direction, and then has guaranteed the life of solenoid valve. In the present embodiment, the second tube 42 is perpendicular to the first tube 41.
