Abstract

The utility model relates to an important improvement of an electromagnetic exhaust device for an air compressor, which acts on a pressing spring, an exhaust spring, a thimble and an exhaust metal ball through the internal pressure variation in an air compressor cylinder and the suction effect of an electromagnetic valve to open or close an exhaust outlet, and causes high-pressure gas with oil mist and water vapour to be exhausted from discharge holes through the exhaust outlet, which avoids the formation of oil dirt to be bonded in an electromagnetic valve core and on the wall of the valve, keeps functions of the electromagnetic valve of discharging and closing gas stable, and avoids the phenomena that an electromotor is switched on under the condition of high load and burned. The utility model can be used for all air compressors.

Description

Electromagnetic exhaust valve
The utility model is a kind of newly-designed electromagnetism venting gas appliance on the air compressor.
The solenoid valve of the interior adapted of electric control box all adopts the single-pass solenoid valve to come exhaust on the existing air compressor.The single-pass solenoid valve during exhaust, tends to the mist of oil aqueous vapor in the cylinder is taken in the solenoid valve together in high pressure conditions, with the passing of time can make to form grease on valve core of the electromagnetic valve and the valve wall and be bonded together, and makes solenoid valve lose discharging and closes the function of gas.Make motor be in the high load starting condition simultaneously, like this, burn motor easily, and make the interior gas of cylinder not reach rated pressure, thereby can not in high-pressure bottle, inflate.
The purpose of this utility model is that a kind of novel electromagnetism venting gas appliance will be provided, and the defective that it can avoid existing single-pass solenoid valve to exist effectively guarantees that air compressor moves safely and reliably.
The utility model is achieved in that draws a thimble 3 from the spool 2 of solenoid valve, directly withstand on the exhaust Metal Ball 5.During air compressor work, solenoid valve is by upwards adhesive, and thimble 3 is also upwards driven.Lose the exhaust Metal Ball 5 of thimble 3 pressure, under the effect of exhaust spring 7, upwards withstand relief opening 6, stop gaseous emission, make in the air compressor cylinder to be in high pressure conditions, constantly in high-pressure bottle, inflate guaranteeing.When the high-pressure bottle internal pressure reaches rated pressure, motor cuts out, the air compressor cylinder stops inflation, solenoid valve is dead electricity simultaneously, spool 2 presses down exhaust Metal Ball 5 by thimble 3 under the effect of pressing spring 1, and relief opening 6 is opened, cylinder inner high voltage gas is come in from suction port 8, exits to vent hole 4 by relief opening 6 again.Since there is check valve to exist between cylinder and the container, at this moment just can be rapidly with the emptying of cylinder inner high voltage gas.
The utility model can make air compressor when the discharging pressurized gas, gas can not enter in the solenoid valve, thereby the phenomenon of having avoided mist of oil aqueous vapor in the pressurized gas to form grease on spool and valve wall and having bondd, thereby the function that has guaranteed the solenoid valve discharging and closed gas is in steady state all the time.Simultaneously, when the emptying of cylinder inner high voltage gas, piston does not have pressure, and motor just can be in the light load starting state, thereby has eliminated the phenomenon of burning motor because of starting current is excessive.
With reference to the accompanying drawings the utility model is carried out more specific description below.Accompanying drawing is the longitudinal sectional drawing of electromagnetic exhaust valve.
A spool 2, a thimble 3 and a special exhaust Metal Ball 5 are arranged in the electromagnetic exhaust valve.There is a circular hole upper end of spool, in put pressing spring 1, the lower end of spool also goes out to have a circular hole, is enclosed within the upper end of thimble.Following the correcting of thimble withstands on the exhaust Metal Ball.The exhaust Metal Ball be positioned at relief opening 6 below.Relief opening is rounded, and its internal diameter is slightly less than the spherical inner diameter of exhaust Metal Ball.Be root exhaust spring 7 below the exhaust Metal Ball, suction port 8 be positioned at exhaust spring below.The right and left above relief opening all has a vent hole 4.

Claims (1)

1, a kind of electromagnetic exhaust valve, comprise spool, pressing spring, thimble, exhaust Metal Ball, exhaust spring, relief opening, vent hole several sections, it is characterized in that above the spool it being pressing spring, a thimble is arranged below the spool, withstand on the exhaust Metal Ball, the exhaust Metal Ball is positioned at below the relief opening, the root exhaust spring is arranged below the exhaust Metal Ball, be suction port below the exhaust spring, vent hole is arranged on relief opening.
