Electric control two-way valve

Abstract

The electrically controlled two-way valve includes valve body, valve core, sealing parts, drive system and electric control system. The valve body is matched with the sealing part tightly and has no mechanical part communicated with outside. The drive system includes screw, dialing fork matched with the screw and shifted by means of the rotation of the screw, outer magnet pressure contacting with the dialing fork, and inner magnet interacting with the outer magnet and the push rod for the inner magnet to be embedded on. The push rod can shift axially to control the valve core for changing over between two states of opening and closing. The electric control system is provided with step motor.

Description

technical field

[0001] The invention relates to an electronically controlled two-way valve, in particular to a magnetically controlled pilot valve, which belongs to the field of electric valve manufacturing. Background technique

[0002] With the progress and development of society, residents' requirements for air quality and environmental comfort in living space are constantly increasing. Therefore, central air-conditioning has developed very rapidly in recent years. The electric two-way valve is a key component in the air conditioning system. When the system is running, it is always in the working state of motion, so the valve is related to the stability of the system, the level of energy consumption and other important factors and indicators. As far as the current situation is concerned, all high-performance electric two-way valves on the market are produced by western developed countries, and some domestic manufacturers just copy them completely.

[0003] However, no m...
