Embodiment Construction

[0014] As shown in the drawings, the present invention includes a main valve 10, a valve opening position switch 1, a valve closing coil 3, and a valve closing position switch 5. The valve closing position switch 5 is arranged beside the valve opening position switch 1. . A wiring seat 6 is provided beside the valve closing position switch 5. A block mechanism 2 is provided between the valve opening position switch 1 and the valve closing coil 3. The valve opening coil 4 is located below the valve closing coil 3, and a moving iron core 7 is provided near the valve opening coil 4. The lower part of 7 is provided with an auxiliary valve 9, the movable iron core 7 and the auxiliary valve 9 are penetrated by a spool shaft 8, and the spool shaft 8 penetrates to the upper part of the block mechanism 2. The main valve 10 is located below the auxiliary valve 9.

[0015] The working principle is:

[0016] When the valve opening coil 4 is turned on instantaneously, the moving iron core 7 ...

Abstract

The invention relates to a self-hold electromagnetic valve which comprises a main valve, a valve turning-on position switch, a valve turning-off coil and a valve turning-off position switch. A clamping block mechanism is arranged between the valve turning-on position switch and the valve turning-off coil, and a valve turning-on coil is arranged below the valve turning-off coil. A movable iron core is arranged nearby the valve turning-on coil, an auxiliary valve is arranged below the movable iron core, and the main valve is located below the auxiliary valve. According to the self-hold electromagnetic valve, the structure of the valve turning-on coil and the valve turning-off coil is adopted, the electromagnetic valve is powered on instantaneously, safety and energy saving are achieved, and sealing is reliable.

Description

Technical field [0001] The invention relates to a solenoid valve, in particular to a self-holding solenoid valve. Background technique [0002] With the development of society, people have higher and higher requirements for the control technology of urban pipelines. Therefore, the technical requirements for solenoid valves have also increased. At present, most of the open and closed valves in the market have a single coil structure, which is not obvious in terms of energy saving. , The sealing performance is not obvious enough. Summary of the invention [0003] The present invention overcomes the shortcomings of the prior art and proposes a self-retaining solenoid valve. The solenoid valve adopts a double-coil structure of opening and closing valves, instantaneous energization, safety and energy saving, and reliable sealing. [0004] The technical solution of the present invention is: a self-holding solenoid valve, including a main valve, a valve opening position switch, a valve c...
