Description
Technical field
The invention belongs to air strainer technical field, be specifically related to air-gauge automatic drainage filter.
Background technology
The gas of air-gauge need pass through and filter moisture and oil content and then use in introducing air-gauge, the water that existing air-gauge filtrator generally needs artificial regular manual drain to filter out, but sometimes because operator senses greatly the fault of the amount of causing instrument, and hand-actuated has certain difficulty artificially, operate not convenient.
Summary of the invention
Technical matters to be solved by this invention is for above-mentioned defect, provides air-gauge automatic drainage filter, and it can the moisture that falls of effective exhaust filtering and oil content automatically, avoids air-gauge because of the clean fault of source of the gas.
The technical solution adopted in the present invention is as follows:
Air-gauge automatic drainage filter, comprise strainer valve and be located at the drainage cup bottom strainer valve, strainer valve is provided with input port and delivery outlet, axle center place is provided with filter center hole, freeing port is provided with bottom drainage cup, freeing port place is provided with draining valve, described filter center hole is bellmouth, one end that diameter is little communicates with delivery outlet upper, the large one end of diameter lower and and be provided with spinning disk between strainer valve inwall, described spinning disk is provided with inclined hole, spinning disk is provided with filtering ring, filtering ring with strainer valve concentric and its upper end connect with input port wall, filter center hole and delivery outlet junction are also provided with the airstrainer of taper, described input port, delivery outlet, filtering ring, the air inlet of filter center's hole composition turnover type, outlet passageway, filter center's hole hole wall of taper and strainer valve lower body form turned cavities, described drainage cup top is provided with the curved baffle upwards arched upward, baffle plate and cup joint are provided with breach, drainage cup axle center place is provided with hollow axle center pipe, control chamber is provided with bottom the pipe of axle center, control chamber is provided with diaphragm, axle center pipe leads to bottom diaphragm, diaphragm is connected with the spool of draining valve, the axle center pipe at control chamber top is arranged with float, it is protruding that float head hub place is provided with the orifice plate covering axle center pipe upper port, described orifice plate projection is provided with bleeder vent.
Described spinning disk inclined hole is uniformly distributed.
Described filtering ring is that sintering metal is made.
Control chamber corresponding bottom described diaphragm is provided with micropore, and micropore is communicated with outside atmosphere by the pipeline arranged in drainage cup.
The invention has the beneficial effects as follows: adopt such scheme, pressurized air enters the strainer valve of this filtrator by input port, first the dust that the filtering ring filtering particles be made up of sintering metal is larger and foul, then air is producing rotary motion through acting in turned cavities of spinning disk inclined hole, because moisture larger for proportion in air and oil content are thrown to strainer valve inwall by the effect of centrifugal force, moisture and oil content just flow into drainage cup through baffle plate breach, along with the profit in drainage cup increases gradually, float floats, the orifice plate projection on float top just departs from axle center pipe, pressure gas enters into axle center pipe through the bleeder vent of orifice plate projection, the bottom of control chamber diaphragm is entered into again by axle center pipe, diaphragm is heaved, because diaphragm is connected with draining valve spool, draining valve is just opened and the profit in drainage cup is discharged by the diaphragm heaved, entering of bending, outlet passageway guarantee is compressed-air actuated stops the regular hour in strainer valve, contaminant filter is clean and in conjunction with spinning disk, air is turned round in turned cavities to utilize centrifugal principle by moisture, oil content filters out, diaphragm is heaved open draining valve spool under utilizing the buoyancy of water of accumulation in drainage cup to make float position increase to make air enter into control chamber diaphragm by axle center pipe, profit is discharged, profit is discharged rear float decline and is again blocked axle center pipe, restore to the original state under the effect of diaphragm back-moving spring in draining valve spool, so go round and begin again Auto-drainage, structure is ingenious, without the need to manual operation, air-gauge is avoided to break down because source of the gas is unclean.
Accompanying drawing explanation
By the detailed description below in conjunction with accompanying drawing, aforesaid and other object, the feature and advantage of the present invention will become apparent.
Fig. 1 is schematic cross-section of the present invention.
