Description

One mold automatic water discharging valve

The utility model relates to a kind of liquid delivery valve, especially a kind of pattern automatic drain valve.

Present vapour electric car, majority all uses hand-pulling type or the manual discharging valve of hand-wring type, this discharging valve uses inconvenient, unhygienic, can't in time bleed off profit, manually discharging valve is often frozen by low temperature especially in the winter time, put not water outlet, ponding too much build-ups ice, and stops up oil and water seperator and lower pipeline, causes brake failure.

The purpose of this utility model provides a kind of automatic drain valve that a foot brake can be put secondary water of stepping on.

The utility model is achieved like this: in valve body lower end, have air chamber, intermediate portion at air chamber has guide rod, the upper end of guide rod and lower spring socket, below guide rod, has matrix, having the valve bottom below diaphragm is threaded with valve body lower end, has the relay valve suction port in the intermediate portion of valve bottom, in intermediate portion, valve body top, has valve pocket, has valve stamen seat in the intermediate portion of valve pocket, have following valve stamen rubber cushion contacts with following sealing platform in valve stamen seat lower end surface, intermediate portion in valve stamen seat lower end surface is threaded with the upper end of following valve stamen bar, has valve stamen cushion rubber in the underpart groove of following valve stamen bar, following valve stamen bar lower end surface is contacting with the guide rod upper-end surface in the pilot hole down, the outside has following valve stamen breach and relief opening connects on following valve stamen bar, valve stamen rubber cushion on having on the upper-end surface of valve stamen seat, intermediate portion in valve stamen seat upper-end surface is threaded with last valve stamen bar lower end, valve stamen wind ditch on having on the lateral vertical direction of last valve stamen bar middle and lower part, having rubber cushion on the valve body upper-end surface contacts below the supermedial gland of the plug screw of valve body upper end, the oil and water seperator suction port of pilot hole and intermediate portion, plug screw upper-end surface connected on intermediate portion in plug screw had, in last pilot hole, has upper spring, upper spring lower end and last valve stamen bar upper end socket-connect, and the sealing platform is corresponding with last valve stamen rubber cushion on the plug screw lower end has.

When the driver tramps with one's feet down the brake valve pedal, the pressurized air of relay valve enters air chamber by suction port, promote diaphragm, overcome the lower spring resistance, make guide rod promote valve stamen bar down along following pilot hole, because following valve stamen bar, valve stamen seat, last valve stamen bar becomes one, together move upward, this at present valve stamen rubber cushion broken away from down sealing platform, valve stamen bar overcomes the upper spring resistance on this moment, last valve stamen rubber cushion also end contacts with last sealing platform, at this moment air-flow and profit enter valve pocket through suction port by last valve stamen wind ditch in the oil and water seperator, discharge from relief opening from following valve stamen breach, treat that valve stamen rubber cushion and last sealing platform block, at this moment profit no longer discharges; When the pedal pine returns, air chamber pressurized air is discharged to the atmosphere in suction port is got back to relay valve, under the influence of pressure difference, overcome the lower spring resistance, diaphragm is pushed open, go up simultaneously under valve stamen bar, the upper spring effect, valve stamen bar, valve stamen seat, following valve stamen bar are together moved downward, when last valve stamen rubber cushion has broken away from the sealing platform, at this moment, following valve stamen rubber cushion also end contacts with sealing platform down, and at this moment air-flow and profit advance valve pocket from suction port by last valve stamen wind ditch again in the oil and water seperator, discharges through relief opening from following valve stamen breach.

The utility model compared with prior art has following advantage:

1, simplicity of design, rationally distributed, volume is little;

2, do not establish the return-air chamber, save source of the gas;

3, oil extraction water efficient height uses wide;

4, reliable performance, encapsulation is strong, and rate of fault is low, and maintenance is convenient.

Concrete structure of the present utility model and embodiment are provided by the following drawings.

Be that the utility model integral body is cutd open and shown schematic representation under the figure.
