Embodiment 1

[0032] The solenoid valve shown in Figure 1 is composed of a valve body part 1, an inlet connecting pipe 4, two outlet connecting pipes 5 and 6, a control coil 2 and a coil housing 3, among which:

[0033] The control coil 2 is made into a structure with a through hole in the middle, and its external shape is convenient to be assembled in image 3 Inside the coil housing 3 shown.

[0034] The valve body part 1 includes a sleeve 16 as a closed structure, a spacer as a tubular object 11, two sector ring magnets 12, a spacer 13, two valve seats 15a, 15b and a steel ball 14 as a valve core The casing 16 is a round pipe; the spacer is also a round pipe, its outer diameter is slightly smaller than the inner diameter of the casing, and there is an annular groove-shaped recessed part 11a in the middle of the outer surface of the pipe wall, and an annular protrusion 11b is arranged in the middle of the recessed part 11a , offer some through holes on both sides of the annular protrusion...

Embodiment 2

[0041] The bushing of Embodiment 1 can be omitted, and instead of opening a through hole in the recessed part of the spacer as the inlet, the inlet is directly opened on one of the valve seats and arranged in parallel with the outlet on the valve seat, while the control coil is directly installed On the core component described in Embodiment 1, a structure as disclosed in Patent No. ZL03271725.3 is formed, which can also achieve the technical effect of the solution, and will not be repeated here.

Abstract

A bistable magnetic valve connected on the refrigerating machine set for controlling the flow direction of the refrigerant comprises a valve body member and a control coil. The valve body member has a spool cavity, an inlet and two outlets in communication with the spool cavity and a magnetic induction ball valve spool disposed in the spool changing its position by the above control coil to seal the above two outlets selectively.

Description

technical field [0001] The invention is a bistable solenoid valve. Background technique [0002] Traditional solenoid valves are controlled by current holding mode, that is, the required holding current is always passed through the control coil to generate a magnetic field to keep the valve core at the required working position, which not only consumes a lot of energy, but also generates a lot of heat and easily burns the control coil , or deform the control coil skeleton, causing the valve body to fail to work. At present, the bistable solenoid valve that is more popular in the world, its working principle is to combine the electromagnetic force with the permanent magnetic force, and the electromagnetic force generated by the pulse current changes the working position of the valve core to change the position of the solenoid valve between the two working states. Switching, relying on the permanent magnetic force to keep the valve core at the working position to maintain the...
