Description
Technical field
The present invention relates to gas-filtering device field, particularly for the pneumatic filter of float type pneumatic measuring instrument.
Background technology
Float type pneumatic gauging instrument requires very high to the cleannes of gas, the quality of gas filtration directly affects the precision of measurement, so high-precision gas filtration equipment is necessary.Pneumatic filter filter effect on present stage market is bad, lacks multistage filtering, and the gas of filtration and water oil not separately, easily form and pollute.
Summary of the invention
In order to address the above problem, the present invention has designed filter and twice filtration of filter core in pneumatic filter, and three pneumatic filters of having connected, filter in each pneumatic filter and filter core are respectively the filter elements of thick effect, the filter element of middle effect, with efficient filter element, the design of weather board imports to water-oil mixture body in reservoir chamber, again gas and reservoir chamber are separated, a kind of pneumatic filter for floating type air gauge, comprise pneumatic filter housing, weather board, deflector, multifunction switch, tracheae, source of the gas input adapter, pneumatic filter cap, source of the gas out splice going splice, filter, screw, filter core, upper hollow bolt, slide block, spring, lower hollow bolt, bolt discharges water, support, bursting diaphragm, Pressure gauge.It is characterized in that being provided with multifunction switch, when multifunction switch is arranged in a precalculated position, gas permeation switch enters pneumatic filter, and after multifunction switch Rotate 180 degree, pneumatic filter and atmosphere are connected, and the water in pneumatic filter just flow in reservoir chamber.
Gas is through filter core and twice filtration of filter in pneumatic filter, and the effect of this spline filter improves; The design is three air cleaner series connection in addition, and in the pneumatic filter of gas process, the filtering accuracy of filter core is more and more higher.
Gases at high pressure enter in pneumatic filter, by upper hollow bolt, are pressing slide block to move down, and it is closed, and prevent that gases at high pressure from entering reservoir chamber, have so effectively stoped the water-oil mixture body secondary pollution in reservoir chamber.
Bursting diaphragm adopts corrosion resistant plate, the injury to the person and equipment in the time of can effectively preventing unexpected generation.
When multifunction switch is opened, be connected with tracheae, have the gas of certain pressure to enter filter, when multi-functional energy switch cuts out, multifunction switch is connected with atmosphere, and now the pressure in filter is consistent with atmospheric pressure.
Slide block is cylindrical, and under the pressure of gas, slide block moves down the water hole that can be closed to water plate, when in filter, pressure is consistent with atmospheric pressure, and the spring slide block of upspringing, the water droplet on weather board flows in reservoir chamber.
The design's beneficial effect is that design function increases, easy to use; Through being divided into thick effect, middle effect, efficient three-stage filtration, according to different occasions, use various combination, generally, by thick, in, efficiently filter step by step principle, by the dust of different-grain diameter in compressed air, oil stain, moisture content classified filtering, so not only improved filtering accuracy, the clear and definite functions of crossing filter cores at different levels, can extend the service life of filter core, guarantee user's interests simultaneously.This layout structure is reasonable, purifies precision efficient, holds dust amount large, and air pressure resistance loss is little, easy to install; Explosion-protection equipment is set, and security improves.

The specific embodiment
A kind of pneumatic filter for floating type air gauge, comprise pneumatic filter housing 1, weather board 2, deflector 3, multifunction switch 4, tracheae 5, source of the gas input adapter 6, pneumatic filter cap 7, source of the gas out splice going splice 8, filter 9, screw 10, filter core 11, upper hollow bolt 12, slide block 13, spring 14, lower hollow bolt 15, bolt 16 discharges water, support 17, bursting diaphragm 18, Pressure gauge 19, it is characterized in that being provided with multifunction switch 4, when multifunction switch 4 is arranged in a precalculated position, gas permeation switch enters pneumatic filter, after multifunction switch 4 Rotate 180 degree, pneumatic filter and atmosphere are connected, water in pneumatic filter just flow in reservoir chamber, gas is process filter core 11 and filter 9 twice filtration in pneumatic filter, injury to the person and equipment when bursting diaphragm 18 can prevent unexpected generation effectively, three filters are together in series and guarantee to filter the quality of rear air.Gases at high pressure enter pneumatic filter by multifunction switch 4, first by circular-arc gas passage, then pass through deflector 3, make gases at high pressure do high speed rotary motion in pneumatic filter housing 1, under the effect of centrifugal force, bulky grain particle, little water droplet and little oil droplet will be thrown on pneumatic filter housing 1, in their water channels on will the weather board 2 below housing flows to, gases at high pressure enter filter core inside through filter core 11 simultaneously, and then enter into source of the gas out splice going splice 8 through filter 9, then gases at high pressure enter second in the mode by same, medium air filtration unit and high efficiency filter unit in the 3rd pneumatic filter, finally by source of the gas out splice going splice 8, enter into Pressure gauge 19, filtration completes, after filtration completes, multifunction switch 4 Rotate 180 degree, pneumatic filter and atmosphere are connected, pressure in pneumatic filter is the same with ambient pressure, slide block 13 moves upward under the impetus of spring 14, now water channel is opened, oil-water mixture flows in reservoir chamber, backing out the bolt 16 that discharges water emits the moisture in pneumatic filter, prevent impact filtration next time.
The above, be only preferred embodiment of the present invention, not this novelly done to any pro forma restriction, and every any modification, equivalent variations and modification of above embodiment being done according to this novel technical spirit, all still belongs to this novel protection domain.
