Abstract
The invention discloses a flat valve, which comprises an air inlet pipe provided with a circle through hole, a disc pedestal is provided at the rear semi-part of the air inlet pipe, at least two circle location holes are provided on the disc pedestal, the valve is embedded in the circular hole at the head of the air inlet pipe, and an I-shaped through hole is provided on the valve. The flat valve has the advantages that the structure is simple, the valve with the I-shaped through hole is provided at the head of the circle through hole of the air inlet pipe, thereby the inhaled air is in a flat strip shape, thereby data transmitted by sensor laser in an environment detector is more accurate, and the detection precision of the environment monitor is increased.
Description
Technical field
The present invention relates to the air granularity detection device, relate in particular to a kind of flat valve.
Background technology
Along with the continuous precision of science and technology, the production environment of sophisticated product requires also to improve constantly, thereby has impelled the continuous popularization of clean room; In order to detect air quality in clean room, judge airborne granule content situation, people detect by the environment detector that is provided with sensor.Its method is,, then by the admission piece that is arranged on sensor, gas imported in sensor air intake by air sampling tube, then dialyses by the air that the laser that penetrates is sucked, thereby can analyze granule content in air.
But the admission piece on existing environment detector sensor is the circle hole shape structure, makes its diameter of air of suction larger, is not very accurate thereby cause detected data, has reduced the measuring accuracy of sensor.
Summary of the invention
Technical matters to be solved by this invention is that a kind of flat valve that can improve the environment detector accuracy of detection is provided.
In order to solve the problems of the technologies described above, the present invention is achieved by the following technical solutions: a kind of flat valve, has the draft tube that is provided with manhole, described draft tube latter half is provided with disc base, at least be provided with two circular pilot holes on disc base, described draft tube head circular hole has been embedded in valve, is provided with a word through hole on valve.
Compared with prior art, usefulness of the present invention is: this flat gas nozzle structure is simple, manhole head in draft tube is installed the valve that is provided with a word through hole, make the air of suction be flat bar, thereby make the data of environment detector inner sensor laser-transmitting more accurate, improve the accuracy of detection of environment monitor.
Description of drawings:
The present invention is further described below in conjunction with accompanying drawing.
Fig. 1 is a kind of flat gas nozzle structure schematic diagram of the present invention.
In figure: 1, draft tube; 2, disc base; 21, pilot hole; 3, valve; 31, a word through hole.
Embodiment:
Describe the present invention below in conjunction with the drawings and the specific embodiments:
A kind of flat valve shown in Figure 1, have the draft tube 1 that is provided with manhole, described draft tube 1 latter half is provided with disc base 2, is provided with at least two circular pilot holes 21 on disc base 2, described draft tube 1 head circular hole has been embedded in valve 3, is provided with a word through hole 31 on valve 3.
During installation, the valve 3 that at first will be provided with a word through hole 31 is embedded in the manhole of draft tube 1 head, then flat valve is arranged on sensor, and the pilot hole 21 of being punished for a crime on 2 by disk is connected and fixed with sensor.During use, draft tube 1 passes into the outside, and the word through hole 31 from valve 3 enters in sensor, and the word through hole 31 on valve 3 narrows down the air that enters, and increases the transmissivity of sensor internal laser, makes in air the detection of particle more obvious.
This flat gas nozzle structure is simple, manhole head in draft tube 1 is installed the valve 3 that is provided with a word through hole 31, make the air of suction be flat bar, thereby make the data of environment detector inner sensor laser-transmitting more accurate, improve the accuracy of detection of environment monitor.
It is emphasized that: above is only preferred embodiment of the present invention, be not that the present invention is done any pro forma restriction, every foundation technical spirit of the present invention all still belongs in the scope of technical solution of the present invention any simple modification, equivalent variations and modification that above embodiment does.
