no. 2 approach

[0053] The second embodiment is a transformation made on the basis of the first embodiment, and the components having the same structure and function as those in the first embodiment will not be repeated one by one. Here is an explanation of the difference between the two:

[0054] In the second embodiment, the inserts are respectively mounted on the insert grooves provided on the opposite flat surfaces of the flange portions 1022cb / 1022cc / 1022cd, and inserts 1022f1, 1022f2, and 1022f3 are respectively installed on the insert grooves. When winding the coil winding, the inner wire ends of the winding are respectively connected to the tabs 1022f1 and 1022f2, and then wound on the annular spaces 1022cf and 1022cg respectively, thus obtaining the first winding 1022a and the second winding 1022b respectively.

[0055] In this embodiment, since the inserting pieces are respectively arranged on the three collar-shaped parts one by one, they are drawn out through three lead wires resp...

Embodiment approach

[0057] In addition to adopting the positions of the tabs in the first embodiment and the second embodiment, various setting combinations can also be made, as long as the inner wire ends of the first winding and the second winding are respectively connected to the first tab and the second As for the insertion piece, the outer wire ends of the first winding and the second winding are respectively connected to the second insertion piece and the third insertion piece.

[0058] Combine below Figure 10 , Figure 11 , to illustrate the control method and working principle of the solenoid valve coil of the present invention. Figure 10 It is the electromagnetic coil control circuit diagram of the present invention, Figure 11 It is the working principle diagram of the electromagnetic coil of the present invention.

[0059] When the SW1 switch is turned on and the SW2 switch is turned ON, the first winding 1022a of the coil is fed with current, and the direction of the magnetic fie...

Abstract

The invention provides a bistable solenoid valve, which consists of a valve body and a solenoid coil. The solenoid coil comprises a coil component, a magnetic conductor and a permanent magnet, wherein the coil component comprises a coil frame and coil windings wound on the coil frame; a knife edge-shaped part of the coil frame is provided with a plurality of inserts; and thread ends of the coil windings are led in or out of the inserts. The bistable solenoid valve is characterized in that: at least two thread ends are led in or out of the inserts. The invention also provides a method for manufacturing the solenoid valve. In the coil structure of the solenoid valve, due to a double winding structure, a reverse device is not needed to be arranged in a control system, and the problem that the solenoid coil is complex to control in the prior art is solved, so that the control is relatively simple; meanwhile, due to respective control of double windings, the problem of heat generation of the coil in the using process is effectively solved; and compared with the prior art, the bistable solenoid valve can greatly reduce the conduction time of a single coil winding. Therefore, the temperature rise of the coil is reduced, the service life of the solenoid coil is prolonged, and the reliability of the solenoid coil is improved.

Description

technical field [0001] The invention relates to the field of solenoid valves, in particular to a direct current bistable solenoid valve, such as a direct current bistable solenoid valve used in the technical field of refrigeration. Background technique [0002] Solenoid valve is an industrial equipment controlled by electromagnetic, which is used in industrial control system to adjust the direction, flow, speed and other parameters of the medium. Solenoid valves are controlled by electromagnetic effects to achieve desired control. There are many kinds of solenoid valves, and different solenoid valves play a role in different positions of the control system. [0003] Solenoid valves can be divided into AC solenoid valves, DC solenoid valves, bistable solenoid valves, etc. from the power supply. General solenoid valves are composed of valve body parts and coil parts. The following takes the bistable electromagnetic four-way reversing valve as an example to introduce the pri...
