Description
Technical field
The utility model relates to air compressor and gas holder technical field, the device of particularly a kind of energy automatic pollution discharge stain and ponding.
Background technique
At present, in the time of the each input and output gas of the air compressor of use, all can in air compressor and air reservoir, produce impurity, greasy dirt and water.Behind certain interval of time, promptly need the impurity and the sewage of inside are discharged.And traditional air compressor draining mainly is to connect ball valve in tank bottom, if when needing blowdown, all adopts the artificial air reservoir bottom ball valve draining of regularly opening, and causes operational inconvenience and trouble; Though adopt water level or pressure interlocked control solenoid valve to open draining, solenoid valve is little because of weep hole, blocks easily in drainage procedure, spot causes jam in addition, and rate of fault is very high, not only wastes electric energy, increase workload but also strengthen user cost.
The model utility content
The purpose of this utility model is: a kind of air compressor automatic drain valve is provided, the impurity and the sewage of air compressor or tank inside in time can be discharged.And do not need manual operation, need be with automatically controlled with regard to draining automatically yet.
The technical solution adopted in the utility model is: the air compressor automatic drain valve, mainly form by upper press cover, anchor plate, conical surface spool, locking nut, valve body and spring, and there is outside thread to be connected with air compressor or storage tank on the top of upper press cover.It is characterized in that: center hole is arranged at the top of upper press cover, can with the automatic drain valve internal communication.Upper press cover and valve body have one to projecting inward valve seat by being threaded in the upper end of valve body, and valve seat is a conical surface shape.On the conical surface of valve seat, annular groove is arranged, seal ring is arranged in annular groove.A conical surface spool is arranged on valve seat, and cylindrical guide pillar is arranged at the bottom of conical surface spool, is with pressure spring on the guide pillar of conical surface spool.Center hole is arranged at the bottom at valve body, and the guide pillar end of conical surface spool is in the center hole of valve body; Water outlet is arranged at the bottom at valve body.
In order to make spring thrust big, the last plane of conical surface spool can not block the upper press cover center hole, and the plane is fixed with anchor plate on conical surface spool.
When the air reservoir internal pressure is lower than certain value, can realize opening automatically drain valve and carry out draining, when the air reservoir internal pressure is higher than spring thrust, can close automatically.Do not need artificial drainage fully, do not need electrification, energy-saving effect is remarkable.
The working principle of summary air compressor automatic drain valve.Consult Fig. 1.The air compressor automatic drain valve is installed on the drain opening of bottom of air compressor or storage tank.
Closed condition: when air compressor inside is gassiness state, the air pressure of air compressor or tank inside is greater than the thrust of 6 pairs of conical surface spools 3 of spring, the conical surface of conical surface spool 3 is directly against on the seal ring 8 on the conical surface of valve body 5, releases with the air of block air compressor or tank inside;
Opening state: air compressor or storage tank are in use, cause jar internal pressure to be disengaged gradually, when the air pressure of air compressor or tank inside during less than the thrust of 6 pairs of conical surface spools 3 of spring, under the restoring force ejection of spring 6, seal ring 8 on the conical surface of conical surface spool 3 disengaging valve bodies 5, make air compressor or storage tank and drain valve be the state of conducting, the impurity and the sewage of air compressor or tank inside are discharged.
The beneficial effects of the utility model: the utility model air compressor automatic drain valve, can make air compressor or storage tank and drain valve be the state of conducting after the installation, the impurity and the sewage of air compressor or tank inside are in time discharged.This drain valve is easy to install, and does not need manual operation, also need be with automatically controlled with regard to draining automatically.
