Description
Technical Field
The utility model relates to a solenoid valve technical field especially relates to a novel silence solenoid valve.
Background
The electromagnetic valve is an industrial valve body, and all the current electromagnetic valve principles are that a magnetic field is generated by an electromagnetic coil, and then an electromagnetic attraction force is generated by a fixed iron core, so that a movable iron core is attracted to move, and the electromagnetic valve is opened. In this process, since the fixed core and the movable core are attracted to each other, they inevitably collide with each other, thereby generating noise.
The micropump comprises a water pump and an air pump, and is widely applied to daily life, and the noise reduction requirement on the micropump is higher because the using environment of the micropump is generally a home or an office and other commercial places. The miniature electromagnetic valve applied to the miniature pump at present has high noise and can not meet the performance requirements of high-end markets, so that the structure of a product needs to be changed, and the noise is reduced.
Disclosure of Invention
The utility model provides a technical problem lie in to the above-mentioned technique not enough, provide a simple structure, have the cushioning effect of iron core striking, can effectively reduce the noise of solenoid valve during operation, improve the novel silence solenoid valve of producing the product performance.
In order to solve the technical problem, the technical scheme of the utility model is that:
a novel mute electromagnetic valve comprises a base with a U-shaped section, wherein a fixed iron core is arranged in the base, a spring is sleeved outside the fixed iron core, and a coil is sleeved outside the spring; the lower end of the movable iron core is provided with a buffer rubber plug, the buffer rubber plug impacts the pressing block to apply pressure to the spring, and the upper end of the movable iron core is provided with a sealing rubber plug; the movable iron core top be provided with the upper cover for sealed with the base, cover on and be provided with suction nozzle and exhaust nozzle, wherein suction nozzle and the coaxial setting of movable iron core, the motion of movable iron core is when the top sealed plug seal the suction nozzle.
In the above scheme, the fixed iron core and the movable iron core have the same diameter, wherein the surface of the movable iron core is of a rough structure, and the damping sponge is tightly attached to the surface of the movable iron core to damp and reduce the movement speed.
In the above scheme, the coil is internally provided with a movable channel for the movable iron core, the pressing block and the spring to move.
In the scheme, the exhaust nozzle is arranged on the side surface of the upper cover and is communicated with the air inlet nozzle through the inner cavity of the upper cover.
In the scheme, the bottom of the air inlet nozzle is provided with a sealing gasket, and the sealing gasket is matched with the sealing rubber plug to seal the air inlet nozzle.
The utility model discloses a principle lies in having increased damping sponge, buffering plug and sealed plug, and wherein, the damping sponge plays the effect of slowing down to movable iron core, and the buffering plug directly connects the pad between briquetting and movable iron core, the impact force that produces when greatly reduced activity iron core lower extreme striking, sealed plug also can reduce the impact force of activity iron core upper end.
Compared with the prior art, the utility model discloses solenoid valve simple structure has the cushioning effect of iron core striking, can effectively reduce the noise of solenoid valve during operation, has improved the performance of product.
