A kind of energy-conservation non-electric automatic drainage device for air compressor
Technical field:
The present invention relates to a kind of energy-conservation non-electric automatic drainage device for air compressor.
Background technique:
Air compressor is a kind of machine air inspiration also compressed, as everyone knows, air is by the process compressed, moisture in air can be decomposed out and form water droplet, time has been grown, water droplet will gather in the bottom of air compressor, working room is carried out at use air gun, air gun is while ejection pressurized gas, incidentally can spray the globule, moisture contamination can be produced like this to by the object sprayed, the workpiece that particularly some effects on surface purity requirements are high, reject rate can be caused to raise after the globule drops down onto its surface, have producer to devise can self-draining electric air compressor for this reason.
Existing electric air compressor is by arranging control valve in drainage channel, in air compressor, pressure inductor is set, when air compressor inner air pressure is reduced to setting value, control valve will action, discharges the moisture accumulating in air compressing motor spindle, but this structure needs to use electric energy, not environmentally, if control valve loses electrical energy drive, will total failure, can not draining.
Summary of the invention:
The object of this invention is to provide a kind of energy-conservation non-electric automatic drainage device for air compressor.
The energy-conservation non-electric automatic drainage device for air compressor of one provided by the invention, include drainage channel, axial step hole is provided with in drainage channel, shoulder hole injects movable plunger, the first gap is provided with between axial step hole and movable plunger, one end identical with pressure directions of movable plunger is crimped with elastic component, the other end projecting shaft is to shoulder hole and be provided with can the vent plug of axial motion, the second gap is provided with between vent plug and drainage channel, be positioned at drainage hole the one section of place arranging elastic component and be provided with water outlet, water outlet communicates with the first gap.
Described vent plug is ball.
Described movable plunger is T-shaped shape plunger, T-shaped shape plunger injects axial step hole from the one end being crimped with elastic component, the card cap of T-shaped shape plunger is provided with the gap water channel of connection first gap and hypomere drainage channel, elastic component is spring, adjusting screw is provided with at the end of drainage channel, spring is crimped between T-shaped shape plunger and adjusting screw, and water outlet is arranged on the drainage channel wall body between T-shaped shape plunger and adjusting screw.
The invention has the beneficial effects as follows: adopt machine construction principle to realize the automatic drainage function of air compressor, whenever air compressor is in idle condition, when air pressure inside drops to a certain numerical value (this numerical value adjustable elastic part adjusts), air compressor is with regard to Auto-drainage, do not need the extra energy to drive draining, energy saving, and draining is reliable.
Accompanying drawing illustrates:
Fig. 1 is the structural drawing of the present invention's energy-conservation non-electric automatic drainage device for air compressor when closing;
Structural drawing when Fig. 2 is the present invention's energy-conservation non-electric automatic drainage device for air compressor opening water discharge.
Embodiment:
Now elaborate the technical program by reference to the accompanying drawings:
The energy-conservation non-electric automatic drainage device for air compressor of the present embodiment, include the drainage channel 1 vertically arranged, axial step hole 2 is provided with in drainage channel 1, axial step hole 2 is provided with injects movable plunger from bottom, movable plunger is T-shaped shape plunger 3, the first gap 4 is provided with between axial step hole 2 and T-shaped shape plunger 3, one end identical with pressure directions of T-shaped shape plunger 3 is crimped with spring 5, the other end projecting shaft is to shoulder hole 2 and be provided with can the vent plug of axial motion, vent plug is ball 6, ball 6 diameter is larger than axial step hole 2 diameter, the second gap 7 is provided with between ball 6 and drainage channel 1, the card cap 31 of T-shaped shape plunger 3 is provided with the gap water channel 8 of connection first gap 4 and hypomere drainage channel, adjusting screw 9 is provided with at the end of drainage channel 1, spring 5 is crimped between T-shaped shape plunger 3 and adjusting screw 9, drainage channel wall body between T-shaped shape plunger 3 and adjusting screw 9 is provided with water outlet 10, water outlet 10 communicates with the first gap 4.
When air compressor is in running order, namely when air pressure inside is larger, ball 6 pushes down axial step hole 2 owing to promoting ball 6 under air pressure and gravitational effect, axial step hole 2 is closed, block internal high pressure air to flow out from here, under this state, ball 6 promotes T-shaped shape plunger 3 and moves downward, Compress Spring 5; When air compressor is in idle condition, when air pressure inside is reduced to setting value, spring 5 will overcome air pressure inside and gravity, drive T-shaped shape plunger 3 jack-up ball 6, now, the water of air compressor inner accumulated in bottom will discharge outside through epimere drainage channel, the second gap 4, gap 7, first, gap water channel 8, hypomere drainage channel, water outlet 10, just can adjust spring 5 pressure by turn adjusting screw 9, thus regulates the internal pressure value driving self-draining arrangement to open.
The above is only preferred embodiment of the present invention, not does any pro forma restriction to the present invention.Any those of ordinary skill in the art, do not departing under technical solution of the present invention ambit, the Method and Technology content of above-mentioned announcement all can be utilized to make many possible variations and modification to technical solution of the present invention, or be revised as the Equivalent embodiments of equivalent variations.Therefore every content not departing from technical solution of the present invention, the equivalence done according to the shape of the present invention, structure and principle change, all should be covered by protection scope of the present invention.
