Embodiment Construction

[0038] A solenoid valve according to a preferred embodiment of the present invention will be described below with reference to related drawings.

[0039] Figure 3A It is a perspective view of a solenoid valve with part of the structure removed for a preferred embodiment of the present invention, and FIG. 3B is Figure 3A An exploded view of the solenoid valve. The solenoid valve 1 mainly includes a bobbin 11 , a valve rod 12 , a coil 13 , at least one ball 15 and a spring 17 .

[0040] FIG. 4 is a perspective view of the removal part of the bobbin and the valve rod in the preferred embodiment of the present invention. The bobbin 11 has a through hole 111 , and the inner wall of the bobbin 11 is surrounded by a guide groove 113 with multiple turns. The coil 13 is wound on the bobbin 11 . The valve operating rod 12 is a movable iron core, which is arranged in the perforation 111 and can be extended or retracted along the axial direction X of the perforation 111. The circum...

Abstract

The invention discloses an electromagnetic valve comprising a wire winding pipe, a wire coil wound on the wire winding pipe, a valve motion rod and at least one ball body. The wire winding pipe is provided with a through hole, and a multi-turning guide groove is arranged circumferentially on the inner wall of the wire winding pipe. The valve motion rod is arranged in the through hole, can extend outwards or retract inwards along the through hole and is provided with an annular groove circumferentially arranged on the outer wall of the valve motion rod. Each ball body is simultaneously accommodated in the guide groove and the annular groove.

Description

technical field [0001] The invention relates to a solenoid valve, in particular to a holding solenoid valve which replaces a permanent magnet with a mechanism design. Background technique [0002] The traditional holding solenoid valve switches its retracted or extended position by energizing the coil, and the valve rod (valve rod) remains at the position before the power is turned off after the power is turned off. In order to save energy, the traditional holding solenoid valve must use the magnetic force of the magnet to absorb the valve operating rod after the power supply is stopped, so as to fix the valve operating rod in the retracted position, so as to achieve the function of the solenoid valve being normally open. [0003] Figure 1A is a perspective view of a traditional holding solenoid valve, Figure 1B for Figure 1A Dimensional view with some structures removed. The solenoid valve 5 includes at least one permanent magnet 51 , a valve rod 52 , a coil 53 and a s...
