Embodiment
The utility model is described in detail below in conjunction with the accompanying drawings.
Referring to Fig. 1 to Fig. 3, a kind of solenoid electric valve of volume control device, including valve body 21 and it is arranged in valve body 21
Support frame 22, the support frame 22 is provided with electromagnetism passage 221, the electromagnetism passage 221 and is provided with sliding seat
231, the support frame 22 is wound with the magnet coil 24 for driving sliding seat 231, and the lower section of the support frame 22 is set
Bottom set seat 25, is cavity volume between the base 25 and support frame 22, and the base 25 is provided with passway 251, the work
Dynamic seat 231 is connected with valve rod 232, and the external part of the valve rod 232 is connected with the valve head 233 for closing passage mouthful 251, described
Valve rod 232 is arranged with the bellows 26 that can be deformed upon；This solenoid electric valve operationally, utilizes the driving activity of magnet coil 24
Seat 231 about 221, so as to realize being turned on and off for passway 251, injects along electromagnetism passage when needing larger pressure
When, and pressure be more than bellows 26 minimum deformation pressure when, bellows 26 is deformed upon so that cavity volume volume increase
Greatly, so as to extenuate the axial compressive force of valve rod 232 and sliding seat 231, scope, solenoid electric valve are pressed with the appearance for improving solenoid electric valve
Service life extended, it is simple in construction, using relatively reliable.
Further, sleeve pipe 27 is additionally provided with the electromagnetism passage 221, the sliding seat 231 is arranged in sleeve pipe 27
