Description
Technical field
The utility model is related to detection technique field, and in particular to a kind of glue-leakage-resistant leakproof being installed on vacuum transducer
Gas suction nozzle.
Background technology
Vacuum transducer is a kind of pressure sensor commonly used in industrial practice, and it is widely used in various industrial automatic control rings
Border, be related to petroleum pipeline, water conservancy and hydropower, railway traffic, intelligent building, production automatic control, Aero-Space, military project, petrochemical industry, oil well,
Numerous industries such as electric power, ship, lathe, ventilation shaft.
The operation principle of vacuum transducer is that the pressure of medium is acted directly on the diaphragm of sensor, make diaphragm produce with
The micro-displacement that pressure medium is directly proportional, makes the resistance of sensor change, and detects this change with electronic circuit, and changes
One standard signal for corresponding to this pressure of output.
It is the air inlet by fluid sealant and vacuum transducer to have a kind of suction nozzle in the suction nozzle of current vacuum transducer
Mouth connection, but existing air inlet mouth structure air-tightness is not very good, causes certainty of measurement relatively low, it is as a result inaccurate, therefore need
Suction nozzle to existing vacuum transducer is improved.
Utility model content
The purpose of this utility model is to provide a kind of glue-leakage-resistant anti-gas-leak suction nozzle being installed on vacuum transducer, with
Solve caused drawbacks described above in the prior art.
A kind of glue-leakage-resistant anti-gas-leak suction nozzle being installed on vacuum transducer, including it is sequentially connected air inlet pipe one, flange
Step and air inlet pipe two, the air inlet pipe one, flange step and air inlet pipe two are integrally formed, and the external diameter of air inlet pipe two is more than air inlet
The external diameter of pipe one, the inner end of air inlet pipe is connected with butt junction by support, and the outer ring of air inlet pipe two is provided with ring-shaped step, annular table
Rank is provided with some along the diametric breach of air inlet pipe two.
Preferably, the butt junction is provided with cylinder groove.
Preferably, the air inlet pipe one is provided with anti-skid bulge.
Preferably, the flange step is provided with the reinforcement of some circumferential arrays with the junction of air inlet pipe two.
Preferably, the outer rim of the ring-shaped step is provided with chamfering.
The utility model has the advantage of：The air inlet mouth structure that the utility model is used, by the outer ring of air inlet pipe two
Ring-shaped step and breach are set, and the structure design of this step can ensure to store more close between suction nozzle and air inlet
Sealing, and fluid sealant uniform application is enabled to air inlet by being rotated into valve after suction nozzle is connected with air inlet,
It is even closer, firm so as to connect, compared to traditional air inlet mouth structure, significantly improve air-tightness.

Specific embodiment
For technological means, creation characteristic, reached purpose and effect for realizing the utility model are easy to understand, below
With reference to specific embodiment, the utility model is expanded on further.
As shown in Figures 1 to 4, a kind of glue-leakage-resistant anti-gas-leak suction nozzle being installed on vacuum transducer, including connect successively
Tracheae 1, flange step 2 and air inlet pipe 23 are tapped into, the air inlet pipe 1, flange step 2 and air inlet pipe 23 are integrally formed,
More than the external diameter of air inlet pipe 1, the inner end of air inlet pipe is connected with butt junction 5, air inlet pipe to the external diameter of air inlet pipe 23 by support 4
23 outer ring is provided with ring-shaped step 6, and ring-shaped step 6 is provided with some along the diametric breach 7 of air inlet pipe 23.
In the present embodiment, the butt junction 5 is provided with cylinder groove 8, for vacuum transducer air inlet at cylinder
The raised docking of shape, plays a part of guiding.
In the present embodiment, the air inlet pipe 1 is provided with anti-skid bulge 9, it is to avoid occur when air inlet pipe is connected with tracheae
Skid, come off.
In the present embodiment, the flange step 2 is provided with the reinforcement of some circumferential arrays with the junction of air inlet pipe 23
10, the rigidity of flange step 2 can be improved, it is to avoid deforming causes its end face not smooth enough.
Additionally, the outer rim of the ring-shaped step 6 is provided with chamfering 11, inclined chamfering 11 is set, can more easily by it
It is connected with air inlet.
Based on above-mentioned, the air inlet mouth structure that the utility model is used, ring-shaped step is set by the outer ring of air inlet pipe 23
6 and breach 7, the structure design of this step can ensure to store more fluid sealants between suction nozzle and air inlet, and
