Abstract
A kind of experiment compressed air purifying box and gas source purification device.It is made of box body and box cover, wherein the sub-assembly in box body equipped with pneumatic two part, shutoff valve and digital indication flow meter serial communication is fixed in cassette bottom, is separately set up between the charger storage an of digital indication flow meter；The air inlet of connection sub-assembly is connected to gas source pipe, and venthole is connected to the air inlet of testing equipment (oil bath)；Compared with known technology, it is automatically separated with gas and water and obvious visual without being dried, may filter that 50 ~ 70 μm of impurity, the instant flow of gas and total flow digital can be shown, it is easy to use, storage it is easy for installation, the purification of many compressed air sources in laboratory can be widely popularized and applied to.
Description
Technical field
The utility model relates to gas source purification devices.
Background technique
Fuel oil such as aviation kerosine, gasoline, diesel oil will form sticky nonvolatile glue in storage, use process
Substance, abbreviation colloid.The excessively high engine aspirating system that will lead to of gum level generates deposit and bonds intake valve.For
Ensure the safety of gas handling system, the gum level of fuel oil need to be measured to regulate and control and to handle.Such as GB/T 8019-
2008 " evaporation is sprayed in the measurement of fuel gum level " and GB 509-88 " engine fuel existent gum test method " are advised
Detection method is determined.Its basic content is by the sample oil injection of the known quantity beaker of constant weight, and the oil bath for being placed in fixed temperature is recessed
In shape hole, 600mL/s air stream is sprayed to sample oil meter face, keeps temperature and air mass flow to evaporate sample oil 30min, takes out
The cooling weighing residue of beaker, operation is until beaker constant weight repeatedly.The gum level of fuel oil is indicated with mg/100ml.
This test method is obviously very high to the purity requirements of injection to the air stream of sample oil meter face, cannot carry
Moisture and impurity, in case test result is inaccurate or is difficult to make residue in beaker to reach constant weight.However, our practical applications
Compressed air source and conveyance conduit are containing compared with juicy and impurity, and in order to purify the air stream of injection, people are generally adopted
With use for laboratory drying tower, in-built solid state calcium chloride or discoloration silica gel absorb moisture, with cotton fiber impurity screening, then through flow
Meter injection special test equipment, is ejected into the surface of sample oil.But calcium chloride, which meets water, can form the block that sticks together, and be difficult to clean off more
It changes, silicon particle meets water discoloration and is also required to often replacement and dehydration, more troublesome.With the hair of pneumatics and pneumatic element
Exhibition should be possibly realized with the method for physical method substitution chemical cleaning method air.
Utility model content
The purpose of this utility model be design it is a kind of it is simple, easy to use by pneumatic element composed structure, without taking off repeatedly
The test gas source purification device of water process.
The technical solution of the utility model is to design a kind of test compressed air purifying box, is made of box body and box cover,
Wherein the sub-assembly in box body equipped with pneumatic two part, shutoff valve and digital indication flow meter serial communication is fixed in cassette bottom, another attached
If between the charger storage of a digital indication flow meter；The air inlet of connection sub-assembly is connected to gas source pipe, and venthole is set with test
The air inlet of standby (oil bath) is connected to；Box body outer wall is equipped with handle and the lock connection corresponding with box cover of lock seat.
The utility model compared with known technology there is gas and water to be automatically separated and obvious visual, without being dried, can
Filtering 50 ~ 70 μm impurity, gas instant flow and total flow can number show, it is easy to use, store it is easy for installation, can be wide
The general purification for promoting the use of many compressed air sources in laboratory.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
The pneumatic two parts 3- shutoff valve 4- digital indication flow meter 5- handle 6- digital indication flow meter electricity of 1- box body 2- in figure
7- air inlet 8- venthole 9- latches seat between the storage of source.
Specific embodiment
The structure and production usage mode of the utility model are described in detail below in conjunction with attached drawing: as shown, a kind of experiment
With compressed air purifying box, be made of box body (1) and box cover, be equipped in box body (1) pneumatic two part (2), shutoff valve (3),
The sub-assembly of digital indication flow meter (4) serial communication is fixed in cassette bottom, and is set up in box body one digital indication flow meter (4) and filled
Between electric appliance storage (6), air inlet (7) is connected to gas source pipe, and venthole (8) is connected to the air inlet of experimental facilities (oil bath)；Box
Body (1) outer wall is equipped with handle (5) and latches the snap fit of seat (9) and box cover corresponding position.
Embodiment: select pneumatic two part (2) of AC2000 type, 4 parts of shutoff valves (3), MF5712-200 type range of flow 0
The digital indication flow meter (4) of ~ 200L/min is with 4 points of hard tube part serial communications, and two ends are equipped with air inlet (7) and venthole (8) is solid
It is scheduled on the floor for the box body (1) withheld with 0.3mm copper sheet, the charger of digital indication flow meter is placed on digital indication flow meter electricity
Between the storage of source in (6), covers box cover and lock storage.
Box body (1) is stood up in use, opening the lid, air inlet (7) is connected to laboratory compressed air pipe with hose,
Venthole (8) is connected to experimental facilities used with hose, after opening gas source, pneumatic two part (2) can carry out gas and water point automatically
From and impurity screening, according to experimental condition regulation and digital indication flow meter (4) the instant index of discharge adjustment shutoff valve (3) carry out examination
It tests.
It is completed, closes gas source and removes the connection hose on air inlet (7) and venthole (8), close institute in box body
There is switch, covers box cover latching and separately store.
Note: when digital indication flow meter (4) shows not enough power supply, should charge immediately.
Claims (1)
1. a kind of test compressed air purifying box, is made of, it is characterised in that: be equipped with pneumatic two in box body box body and box cover
The sub-assembly of part, shutoff valve and digital indication flow meter serial communication is fixed in cassette bottom, separately sets up the charging of a digital indication flow meter
