Abstract
The invention relates to a seal valve switch electric machine which is suitable for various seal valves. The seal valve switch electric machine comprises a shell body, a stator, a rotor, a rotor shaft, an insulation sleeve and a base. The insulation sleeve is arranged between the rotor and the stator and fixed on the base through bolts. A first seal ring is arranged between the insulation sleeve and the base. The upper end of the rotor shaft is installed on the top wall of the insulation sleeve, and the lower end of the rotor shaft stretched out of the base. The stator comprises stator iron cores and stator coils. Each stator coil is arranged on the corresponding stator magnetic pole in a sleeved mode. An annular groove which is used for placing seal rubber rings is formed in the bottom surface of the base. The shell body is fixed on the base through bolts. The seal valve switch electric machine has the advantages that due to the fact that the motive seal of the valve is replaced by the static seal of the valve, the seal effect is greatly improved; due to the fact that a switch of the valve is controlled by electric pulse, the flow of media in pipelines can be accurately controlled; and the seal valve switch electric machine is simple in structure and low in cost.
