Mixed gas diffusion sprayer
Technical field
The present invention relates to a kind of ejecting device, especially relate to mixed gas diffusion sprayer mouth mask and the test of mask slip.
Background technology
Usually shower nozzle can be used for liquid spraying system, also can be used for the detection of labor protection equipment, as the detection of mouth mask or mask.Mouth mask or mask are mainly used in work posts such as plating, paint, system lead powder, sewer, pitch processing, pickling, ink pigment making.If be used for liquid spraying system, be power usually with compressed air, adopt the high-pressure spray technology, constitute the high-pressure gas-liquid two phase flow when making liquid flow through pipeline valve, finally make the atomization of liquid.This technology at home, outer application comparative maturity all, but have the limitation of using: the method is only applicable to the diffusion atomizing of liquid, and is not suitable for the diffusion of pure gas or mist.For the detection of the mouth mask of reality or mask, can not meet the demands.
Therefore, design the shower nozzle that an energy spreads pure gas or mist, just seem very crucial for the detection of mouth mask or mask.
Summary of the invention
The objective of the invention is to problem, a kind of mixed gas diffusion sprayer is provided at the prior art existence.Have simple in structure, overall volume is less relatively, cost is lower, can guarantee that diffusion effect is good, and manufacturing process is simple relatively, can be fit to gas and use.
For achieving the above object, the present invention adopts following technical proposals:
A kind of mixed gas diffusion sprayer comprises gas conduit, gas buffer chamber, playpipe and diffuser.It is characterized in that: top, described gas buffer chamber air inlet is connected with gas conduit rotary seal circle, and the bottom with fixedly connected with playpipe upper end, rotational speed regulation is carried out by arrangements for speed regulation in described gas buffer chamber, and the top of described playpipe lower end and described diffuser is bolted to connection.Described diffuser is a demountable structure: its top has aperture, and this aperture is installed the playpipe that draw the gas buffer chamber, and fixedly connected by screw, and its underpart is the sieve plate that is covered with aperture, and this sieve plate connects diffuser top by screw all around.
The structure of above-mentioned arrangements for speed regulation is: described gas buffer chamber is the column type thin-wall construction, be installed on the gas conduit bottom, be rotationally connected by sealing ring and gas conduit, the fixed installation of gas buffer chamber outer wall one and gear, another gear is installed on the motor output shaft, these two gears engaged.
The present invention compared with prior art, have following conspicuous outstanding substantive distinguishing features and remarkable advantage: overall structure of the present invention is simple, and it is rationally distributed; The present invention has the advantage that simple adjustment adapts to multiple situation; The present invention can regulate the diffusion that needs voluntarily.Both can be used as the mist diffusion of the slip test of mouth mask and mask, also can be used as common gas diffuser.

The specific embodiment
Embodiment one: the preferred embodiments of the present invention accompanying drawings is as follows: referring to Fig. 1.This testing arrangement comprises gas conduit 1, gas buffer chamber 6, playpipe 4 and diffuser 5.Described gas buffer chamber 6 top air inlets are connected with gas conduit 1 rotary seal circle, and the bottom with fixedly connected with playpipe 4 upper ends, rotational speed regulation is carried out by arrangements for speed regulation in described gas buffer chamber 6, and the top of described playpipe 4 lower ends and described diffuser 5 is bolted to connection.Described diffuser 5 is demountable structure: its top has aperture, and this aperture is installed the playpipe 4 that draw gas buffer chamber 6, and fixedly connected by screw, and its underpart is the sieve plate that is covered with aperture, and this sieve plate connects diffuser top by screw all around.
Gas conduit 1 is a metal resistant material circular tube structure, and gas conduit 1 one ends are connected with gas buffer chamber 6, and seal 8 is installed in the junction.Gas conduit 1 other end connects external source of the gas.
Embodiment two: present embodiment and embodiment one are basic identical, special feature is: the structure of described adjusting device is: the structure that it is characterized in that described arrangements for speed regulation is: described gas buffer chamber 6 is the column type thin-wall construction, be installed on the gas conduit bottom, be rotationally connected by sealing ring and gas conduit 1, one of gas buffer chamber 6 outer walls fixed installation and gear 7, another gear 3 is installed on motor 2 output shafts, these two gears, 7,3 engagements.
Playpipe 4 is the little tubular construction of thin-walled, the uniform side that is installed on gas buffer chamber 6, and form certain included angle with the gas buffer chamber.Playpipe 4 lower ends are connected with diffuser 5 and seal.
The principle of present embodiment is as follows: during use, only the gas of need diffusion need be used pipe fitting connect gas conduit 1.Gas enters gas buffer chamber 6 after by gas conduit 1, and the gas that enters gas buffer chamber 6 will be through will on average entering the playpipe 4 that is attached thereto after the diffusion fully.Gas will pass through and ejection from extraction plate after entering diffuser 5 behind the playpipe 4 uniformly.During use, rotate, finally drive gas cushion 6 circumference and rotate, and drive connected playpipe 4 and diffuser 5 is pretended to know together by gear 3 driven gears 7 of motor 2 control, when guaranteeing to use gas evenly.Can reach the purpose of the control uniformity by the rotating speed of regulating motor 2.
