Magnetic rotor structure and power-driven switching valve

Abstract

The invention provides a magnetic rotor structure and a power-driven switching valve, wherein the power-driven switching valve comprises a magnetic rotor structure, a valve seat, a slide block, and an outer cover sleeve of the power-driven switching valve; the magnetic rotor structure comprises a magnetic rotor, a shaft and a key; one end of the shaft is arranged in a valve seat bottom hole of the valve seat; the key is used for clamping with a key groove of the slide block; the outer cover sleeve of the power-driven switching valve is sleeved on the valve seat, wherein the distance between the magnetic rotor and the inner wall of the outer cover of the power-driven switching valve is 0.2mm-1.0mm. According to the technical scheme provided by the invention, through the arrangement of the distance of 0.2mm-1.0mm between the magnetic rotor and the inner wall of the outer cover of the power-driven switching valve, and through the arrangement of at least one through hole which is arranged on the magnetic rotor and is communicated with the upper part and the lower part of the magnetic rotor, the technical defect that the normal valve opening of the power-driven switching valve is influenced because of the pressure difference of a medium existing between the upper part and the lower part of the magnetic rotor in the prior art is overcome.

Description

technical field [0001] The invention relates to the field of refrigeration engineering, in particular to a magnetic rotor structure and an electric switching valve. Background technique [0002] In the prior art, referring to Chinese patent CN101270826A, this patent application relates to an electric switching valve, which includes a magnetic rotor structure, and as figure 1 It is shown in the three-dimensional structural diagram of the magnetic rotor structure in the prior art, the magnetic rotor structure includes the magnetic rotor 11, the shaft 12 and the key 13; in the practical application of the refrigeration cycle system, the medium flows in from the inlet to fill the entire valve body, The slider engaged on the magnetic rotor 11 through the key 13 rotates with the shaft 12, so that at least one outlet on the flat bottom surface of the valve seat is opened, due to the magnetic rotor 11 and the inner wall of the electric switching valve housing of the electric switchi...
