Problems solved by technology

[0003] However, no matter the electric two-way valves produced in developed countries or domestically produced, they all adopt the external mechanical structure design. After long-term use, leakage will occur due to mechanical wear and tear, and they must be replaced. The service life is not long.
Valves using magnetic control often cause problems such as lax closing, small closing force, poor operating performance, long operating time, and slow response speed.
Ordinary motor valves have the disadvantages of complex structure, short working life, working noise and inability to achieve precise control

Embodiment Construction

[0029] Describe content of the present invention in detail below in conjunction with specific embodiment:

[0030] figure 1 As shown in , the main part of the valve is composed of a valve body 2, a valve core 4, an inner sleeve 3, a sealing member 6, a push rod 8 and an outer magnet 7. In the valve body 2, the water flow or air flow flows from the chamber P1 to the chamber P2, and the up and down movement of the valve core controls the opening or closing of the valve. The inner sleeve 3 is closely connected with the valve body, and the inside of the inner sleeve 3 is the valve core 4, The valve core 4 realizes sealing between the top sealing ring 10 and the inner casing and can move relatively. A sealing part 6 is installed on the top of the valve core, and the sealing part 6 is roughly "n" shaped and closely connected with the valve body. Due to the function of the sealing part, the valve completely prevents leakage. A push rod 8 is arranged in the inner cavity of the seali...

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...
