Further, the position that the filter pulp of spool section is put, changed the direction of gas flow, accelerates the globule and resolve into rapidly steam.
Further, filter house utilizes aluminum alloy casing, reaches heat radiation efficiently.
In order to understand better above embodiment, below the operation principle with this compressed air treatment device describes, so that those skilled in the art understand better.
Undressed compressed air enters compressed air treatment device, and undressed compressed air may carry the harmful substances such as dust, oil, iron rust and moisture.
Compressed air enters this device, be introduced into filter house 3, the position shared due to the compressed air of same volume increases suddenly, the compressed air molecular gap reduces, compressed air expansion heat release, filter house 3 temperature suddenly increase, the moisture that is attached to filter house wall forms steam, and the condensation vapor that is greater than 4 microns becomes the globule, and the globule and the globule clash in the process of heat release, thereby be combined into the globule that volume is larger, and be adsorbed on device, finally flowing into water trap 4, hot gas dispels the heat by aluminum alloy casing simultaneously, relative, compressed air obtains cooling.
Above process, when compressed air enters filter house 3, by coalescent effect, the globule that carries larger impurity particle is adsorbed on device, condensation vapor becomes the large particle diameter globule, along with the time increases, when the globule is prepared to separate, at this moment compressed-air actuated movement velocity slows down, and makes the globule condense on water trap.The water droplet that finally carries impurity particle flows to drainage position, by water trap, water is discharged.
Then, the filter cylinder 201 of filter core section 2 and filter pulp 204 will be less than the globule of 4 microns with the speed of 200～300 kilometer per seconds and bring filter cylinder 201 into, because gas will pass through the specific arrangement structure of filter pulp 204, need not stall to change direction, thereby formation air swirl, and making compressed air accelerated motion, the globule is decomposed to form rapidly steam.
When compressed air passes through filter pulp 204, filter pulp 204 is comprised of fibrous filter net, and gas motion can produce thousands of micro cyclones when this fibrous filter net, the compressed air motion of need to raising speed, impurity is further filtered, and finally forms the compressed air that meets instructions for use.
The compressed air that cleanliness factor meets instructions for use enters pressure-reducing valve 1, drying filter output also enters through the air inlet of pressure-reducing valve 1, requirement according to the terminal gas equipment, rotation knob 108 control and regulation springs 105, thereby control by balance diaphragm 102, spool 103, back-moving spring 106 gas flow that enters and export pressure-reducing valve 1, thereby control gas pressure.
When turning clockwise knob 108, regulating spring 105 moves down balance diaphragm 102 and spool 103, and back-moving spring moves down thereupon, and back-moving spring is controlled air inlet 101 and increased aperture, and the tolerance that enters pressure-reducing valve is increased.If while being rotated counterclockwise knob 108, the aperture of air inlet 101 reduces, and the tolerance in pressure-reducing valve reduces thereupon.
If the instantaneous rising of the air pressure of inputting from device for drying and filtering, air pressure in pressure-reducing valve also will increase, make the air pressure of balance diaphragm 102 below air chambers raise simultaneously, the corresponding increase of thrust produced on balance diaphragm 102, this thrust has been destroyed original equilibrium of forces, balance diaphragm 102 is moved up, have small part gas to discharge through spout hole 104.When moving on balance diaphragm 102, band movable valve plug 103 and back-moving spring move up, and the aperture of air inlet 101 reduces thereupon, and the gas entered in pressure-reducing valve 1 reduces, and the pressure in pressure-reducing valve 1 reaches balance in time gradually.
If the instantaneous decline of the air pressure of inputting from device for drying and filtering, the air pressure in pressure-reducing valve also will decrease, and now make balance diaphragm 102 move down, spool 103 and back-moving spring 106 move down thereupon, air inlet 101 apertures increase, and the gas entered in pressure-reducing valve increases, and makes output pressure get back to original value.
Be rotated counterclockwise knob 108, regulating spring 105 is restored to the original state, gas acts on the active force that thrust on balance diaphragm 102 is greater than regulating spring 105, and balance diaphragm 102 upsweeps, and spool 103 and back-moving spring 106 upwards, make air inlet 101 close.Now, relief valve seat 109 is thrown off, and the gas of balance diaphragm 102 below air chambers is just discharged through spout hole 104.
Pressure-reducing valve 1 is the throttling action decompression that relies on air inlet 101, rely on the overflow effect voltage stabilizing of balance diaphragm 102 equilibrium of forces effects and spout hole, regulating spring makes output pressure change within the specific limits, thereby makes through the gas pressure of pressure-reducing valve output stable.
As can be seen here, the gas after device for drying and filtering is processed enters pressure-reducing valve, and by adjusting knob, thereby control and regulation spring, spool and back-moving spring make to export after the gas voltage stabilizing.When air pressure fluctuation, the balance diaphragm is up moved, cause balance diaphragm and spool to separate, air pressure overflows pressure release from the spout hole in the middle of the balance diaphragm, when the gas pressure in the pressure-reducing valve after pressure release is consistent with default pressure, the balance diaphragm recovers, and pressure-reducing valve maintains the original state.
Compressed air is by after device for drying and filtering, enter pressure-reducing valve, control the balance diaphragm by the regulating spring in pressure-reducing valve, spool and back-moving spring, thereby control angle and gas overflowing that air inlet is opened, and then regulate compressed-air actuated pressure, make the gas pressure that exports the terminal gas equipment to stable, due to compressed air from dry filter, in the process of steady pressure, all in same device, carry out, last processing finishes by next parts, to be processed, therefore be not easy to bring into impurity, cleaning gas and the stable gas pressure of output, thereby make the terminal gas equipment life-span improve, reduce maintenance cost, do not need to use appendix to connect different devices simultaneously, reduce usage space, Cost reduction, raise the efficiency.
Further, device for drying and filtering is by the coalescent effect of gas, by impurity and moisture removal.
Further, the shell of filter house is aluminum alloy casing, while making compressed air enter filter house, and heat radiation rapidly.
The those skilled in the art can be well understood to, and for convenience and simplicity of description, the specific works process of the device of foregoing description, can, with reference to the corresponding process in preceding method embodiment, not repeat them here.
The above, above embodiment only, in order to the technical solution of the utility model to be described, is not intended to limit; Although with reference to previous embodiment, the utility model is had been described in detail, those of ordinary skill in the art is to be understood that: its technical scheme that still can put down in writing aforementioned each embodiment is modified, or part technical characterictic wherein is equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution break away from the spirit and scope of each embodiment technical scheme of the utility model.
