Description
Technical field
The present invention relates to a kind of accuracy of detection it is high, without calibration, can directly and airborne particle counter or plankton
Sampler connection is used and small volume, lightweight, the gases at high pressure diffuser for being easy to carry mobile.
Background technology
All the time, the purification rank for the compressed air being input in toilet must be identical with the rank of toilet, and
And the plankton number in compressed air also has to comply with the requirement of the toilet.Therefore, the compressed air of input must be first
Depressurized, water-oil separating, after elementary, middle and high three-stage filtration, it is met the requirement of the toilet could input.Current city
The accuracy of detection that the instrument of compressed air quality is can detect on field is relatively low, it is impossible to be accurately detected whether compressed air meets cleaning
The use requirement of room.Therefore, we have developed a kind of accuracy of detection it is high, without calibration, can directly and airborne particle counter or
The connection of plankton sampler is used and small volume, lightweight, the gases at high pressure diffuser for being easy to carry mobile.
The content of the invention
A kind of accuracy of detection height is provided the invention aims to overcome the deficiencies in the prior art, without calibration, can be straight
Connect and used and small volume with airborne particle counter or the connection of plankton sampler, lightweight, be easy to carry mobile height
Press gaseous diffuser.
To reach above-mentioned purpose, the technical solution adopted by the present invention is：A kind of gases at high pressure diffuser is provided, sealing is included
Cavity；The side of the seal cavity is provided with air inlet pipe, and opposite side is provided with escape pipe；The air inlet pipe, seal cavity, go out
Tracheae is sequentially communicated；The air inlet pipe can be connected with gases at high pressure feeding mechanism, the escape pipe energy and airborne particle counter
Or plankton sampler device is connected；The volume of the seal cavity is sufficiently large, when gases at high pressure pass through air inlet pipe and pressure regulation
Valve enters after seal cavity, and pressure drastically declines, and realizes the purpose of gases at high pressure diffusion.
It is preferred that, pressure regulator valve is provided with the air inlet pipe, the pressure regulator valve can be used for regulation gases at high pressure feeding mechanism
Pressure when being supplied into seal cavity.
It is preferred that, the escape pipe is provided with flowmeter, and the flowmeter is used to provide the gas of corresponding discharge to ensure
The accuracy of the sampling quantity of airborne particle counter or plankton sampler, makes sampler be sampled for malleation, will not produce negative
Pressure influence testing result.
It is preferred that, the seal cavity is made of stainless steel.
Due to the utilization of above-mentioned technical proposal, the present invention has following advantages compared with prior art：
The volume of seal cavity of the present invention is sufficiently large, when gases at high pressure by air inlet pipe and pressure regulator valve enter seal cavity
Afterwards, pressure drastically declines, and realizes the purpose of gases at high pressure diffusion；
The setting of flowmeter can guarantee that the accuracy of the sampling quantity of airborne particle counter or plankton sampler, make sampler
Sampled for malleation, negative pressure influence testing result will not be produced.Simply, flowmeter and pressure regulator valve are set structure design of the present invention simultaneously
Put, be easy to adjust and dismount, control mode is succinctly directly perceived；, can directly and airborne particle counter and routine use is without calibration
Or the connection of plankton sampler is used, furthermore small volume of the present invention, lightweight, be easy to carry movement.
