Description
Technical field
The utility model relates to the air-operated solenoid valve technical field, refers more particularly to a kind of self-closing electromagnetic valve.
Background technique
Solenoid valve is the industry equipment with Electromagnetic Control, is used in direction, flow, speed and other the parameter of adjusting medium in the industrial control system.Solenoid valve utilizes the effect of electromagnetism to control, and main control mode is controlled by relay.Like this, solenoid valve can cooperate different circuit to realize the control of expecting, and the precision and the flexibility of control can both guarantee.Solenoid valve has a variety of, and different solenoid valves plays a role at the diverse location of control system.
At present general solenoid valve generally can only rest on a limit position for a long time under no electric situation, if stop for a long time at another limit position, the long-term energising of needs just can realize, so there is short, problem such as energy consumption is big in working life in these solenoid valves.
The model utility content
At the deficiency that exists in the above-mentioned technology, the utility model provides the self-closing electromagnetic valve of a kind of power saving, environmental protection.
For achieving the above object, the utility model provides a kind of self-closing electromagnetic valve, comprise shell, skeleton, permanent magnet, Returnning spring and electromagnetic coil, also comprise secured core, movable slide bar, push rod and copper plug, described permanent magnet is adsorbed in described secured core bottom, described push rod is arranged on the movable slide bar, described push rod is positioned in the described skeleton inner chamber, described push rod upper end is fixed with the sealer head, described Returnning spring is positioned between described secured core and the described movable slide bar, described copper plug is arranged at described skeleton top, is provided with seal ring between described secured core and the described skeleton.
Described sealer head moves around with the push rod that is fixed on the movable slide bar, is used for blocking the vent of copper plug.
Described skeleton is arranged at the inside of described shell, and shell is lived skeletal fixation, plays the effect that improves magnetic force.
Described electromagnetic coil is connected with electric wire, is used for being connected with power supply.
Described electromagnetic coil is arranged on the skeleton.
Described permanent magnet is adsorbed on described iron core bottom, can produce a permanent-magnetic field.
Described seal ring is arranged between described secured core and the described skeleton, plays the effect of sealing.
Compared with prior art, the utlity model has following advantage:
The self-closing electromagnetic valve that the utility model provides, under spring action, block an air outlet hole, allow air-flow flow out, produce magnetic force during electromagnetic coil moment energising by the another one air outlet hole, inhale the resistance that moving movable slide bar overcomes Returnning spring, move to another limit position; During outage, movable slide bar overcomes spring force under the effect of permanent-magnetic field, is adsorbed on for a long time on the end face of secured core, and the sealer head is blocked the vent of copper plug along with the push rod that is fixed on the movable slide bar moves, and allows air-flow flow out from the former air outlet hole of blocking.Electromagnetic coil of the present utility model is moment energising, solenoid valve can need not energising according to usage requirement conversion work seat when long-term work, has reached power saving, energy-conservation effect.

Working principle:
Electric wire is connected with electromagnetic coil, is used for being connected with power supply, and electromagnetic coil is wrapped on the skeleton, can generate an electromagnetic field during energising.Permanent magnet is adsorbed on the bottom of secured core, produce a permanent-magnetic field, push rod is fixed on the movable slide bar, and the sealer head is fixed on the push rod, and be positioned over skeleton inside together, Returnning spring is positioned between secured core and the slide bar, makes slide bar drive the sealer head and moves, and blocks the vent of the copper plug that is fixed in the skeleton top, seal ring is between secured core and skeleton, play the effect of sealing, shell is lived skeletal fixation, has improved magnetic force and has been convenient to and installed.
The utility model is blocked an air outlet hole under spring action, allow air-flow be flowed out by the another one air outlet hole, produces magnetic force during electromagnetic coil moment energising, inhales the resistance that moving movable slide bar overcomes Returnning spring, moves to another limit position; During outage, movable slide bar overcomes spring force under the effect of permanent-magnetic field, is adsorbed in for a long time on the end face of secured core, and the sealer head is blocked the vent of copper plug along with the push rod that is fixed on the movable slide bar moves, and allows air-flow flow out from the former air outlet hole of blocking.
More than disclosed only be several specific embodiment of the present utility model, but the utility model is not limited thereto, any those skilled in the art can think variation all should fall into protection domain of the present utility model.
