Abstract

The invention relates to the technical field of valve control, and discloses a solenoid valve. The solenoid valve comprises a valve body assembly and a coil assembly; the valve body assembly comprises a valve sleeve, a static iron core fixed at one end in the valve sleeve, a valve seat fixed at the other end in the valve sleeve and a movable iron core slidably arranged in a valve cavity of the valve sleeve; a first connecting pipe is welded and fixed on the side part of the valve sleeve and communicates with the valve cavity; a second connecting pipe is fixed in the axial direction of the valve sleeve and communicates with a valve port of the valve seat; and a guiding through hole necked inwards is formed in the side part of the valve sleeve, a protruding part is arranged at the front end of the first connecting pipe, and the front end of the first connecting pipe penetrates through the guiding through hole to be inserted into the valve cavity. According to the technical scheme, through design improvement, the solenoid valve works reliably and can become small.

Description

technical field [0001] The invention relates to the technical field of valve control, in particular to an electromagnetic valve. Background technique [0002] Solenoid valves are used in a wide range of fields, such as figure 1 What is given is a solenoid valve structure commonly used in the prior art. [0003] Please refer to figure 1 The solenoid valve in the prior art includes a coil 2' connected to the sleeve 1', a valve seat 3' fixed at the lower end of the sleeve 1', a static iron core 7' is provided at the upper end of the sleeve 1', and the sleeve There is a moving iron core 4' inside the pipe 1', a valve core 41' is fixed at the lower end of the moving iron core 4', a spring 9' is arranged between the moving iron core 4' and the static iron core 7', and the valve seat 3' Metal such as copper material is formed by machining and welded on the sleeve 1', the valve seat 3' is provided with an inlet connection 31' and an outlet connection 32' for the medium to circula...
