Problems solved by technology

[0005] However, this prior art only operates the solenoid valve manually, and thus has the problem of being unable to quickly respond to a power failure.
[0006] In addition, because the solenoid valve cannot work normally due to power failure, there is a problem that the blocking and guiding control cannot be performed in time

Abstract

PURPOSE: A power saving solenoid valve is provided to selectively implement an manual control and an electric control and to stabilize operation of the power saving solenoid valve. CONSTITUTION: A power saving solenoid valve comprises a valve body(10), a valve seat(20), a plunger(30), a core(40), a first coil(L1), a permanent magnet(50), a second coil(L2), a restoring spring(60), and a control circuit. A passage is formed inside the valve body. The valve seat opens and closes the passage of the valve body while sliding. The plunger is coupled to the valve seat and is slid along a longitudinal direction. The core is arranged in a position to be spaced from the plunger and is composed of a ferromagnetic substance. The first coil and the permanent magnet magnetize the core. The second coil attenuates magnetic force of the core magnetized by the permanent magnet. The restoring spring elastically support so that the plunger can be apart from the core. The control circuit controls the operation of the first and second coils.

Description

technical field [0001] The invention relates to an energy-saving electromagnetic valve, in particular to an energy-saving electromagnetic valve for opening and closing passages through electrical control. Background technique [0002] The solenoid valve has an electromagnet and a valve, and the magnetic force is changed by energizing the electromagnetic coil, and the valve is opened and closed in conjunction with this, thereby opening or blocking the flow of fluid. [0003] Generally speaking, the solenoid valve is aligned with the middle of the flow passage, and is mainly used for steam, water, and refrigerant, and its structure is different according to different applications. [0004] Registered Patent No. 497632 is disclosed as an example of a prior art document. This registered patent opens and closes the solenoid valve by manual operation in the event of sudden accidents such as power outages. [0005] However, this prior art only operates the solenoid valve manually...
