Problems solved by technology

[0002] In the existing electromagnetic reversing valve, there is only one stable working position that does not need to consume electric energy, but when the electromagnetic reversing valve is in an unstable working position, the electromagnet needs to be continuously energized to consume electric energy
This greatly improves the use cost of the electromagnetic reversing valve; among the existing electromagnetic valves, only the bistable electromagnetic energizing valve can have two stable working positions; however, for the reversing valve, it is often necessary to have three or three More than one working position to meet the requirements of use

Embodiment Construction

[0030] The present invention will be further described below in conjunction with accompanying drawing.

[0031] Such as figure 1 , 2 , 3 and 4, a cam-type multi-stable reversing valve includes a valve seat 1, a valve core 2, a first electromagnet 3, a second electromagnet 4, a moving permanent magnet 5, a suction block 6 and a working bit switching mechanism. Both the first electromagnet 3 and the second electromagnet 4 are de-energized electromagnets; the de-energized electromagnets have magnetism when no power is applied, and the magnetism disappears after being energized. The suction block 6 is made of a magnetic material (a material that can be magnetized). The valve seat 1 is provided with a valve core placement channel. The first electromagnet 3 and the second electromagnet 4 are respectively fixed at both ends of the spool placement channel. The spool 2 is elongated and forms a sliding pair with the spool placement channel. The valve core 2 is located between the ...

Abstract

The invention discloses a cam-type multi-stable reversing valve and a working position switching method thereof. In existing electromagnetic valves, only multi-stable electromagnetic elastic valves have two stable working positions. The cam-type multi-stable reversing valve comprises a valve seat, a valve element, a first electromagnet, a second electromagnet, a movable permanent magnet and a working position switching mechanism; the first electromagnet and the second electromagnet both adopt power-lossing type electromagnets; the working position switching mechanism comprises a support, a rotation shaft, a one-way bearing, a torsional spring, a cam, a pushing rod and a transmission assembly; and the transmission assembly comprises a driven iron block, a sliding block, a connecting rod anda rocking rod. According to the cam-type multi-stable reversing valve and the working position switching method thereof, the valve element of the reversing valve is driven by a cam mechanism, therefore, electric energy does not need to be consumed when the reversing valve is located at all the working positions, and the using cost of the electromagnetic valve is greatly reduced; and in addition,the defect that in an existing electromagnetic reversing valve, due to the fact that electromagnets need to be electrified for a long time, the electromagnets are prone to being damaged is overcome, and the service life of the reversing valve is prolonged.

Description

technical field [0001] The invention belongs to the technical field of electromagnetic valves, and in particular relates to a cam type multi-stable reversing valve and a working position switching method thereof. Background technique [0002] In the existing electromagnetic reversing valve, there is only one stable working position that does not need to consume electric energy, but when the electromagnetic reversing valve is in an unstable working position, the electromagnet needs to be continuously energized to consume electric energy. This greatly improves the use cost of the electromagnetic reversing valve; among the existing electromagnetic valves, only the bistable electromagnetic energizing valve can have two stable working positions; however, for the reversing valve, it is often necessary to have three or three more than one working position to meet the requirements of use. Therefore, it is very important to design a reversing valve in which all working positions are...
