Description
Technical field
The utility model is related to detection technique field, more particularly to a kind of anti-blocking fast knot structure of suction nozzle diaphragm seal.
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.
Gask-O-Seal in the suction nozzle of current vacuum transducer, under stress can be along retaining when air inlet
Cylinder rises, and so as to block gas port, allows faulty sensor below.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of anti-blocking fast knot structure of suction nozzle diaphragm seal, existing to solve
There is caused above-mentioned multinomial defect in technology.
To achieve the above object, the utility model provides following technical scheme：A kind of anti-blocking fast knot of suction nozzle diaphragm seal
Structure, including suction nozzle body, the suction nozzle body include tubulose connection valve, flange step, connection circle and retaining cylinder, institute
State flange step to be arranged between tubulose connection valve and connection circle, be provided with the middle of the flange step and be connected in valve with tubulose
The circular hole of footpath casing, is uniformly provided with three retreat stop blocks, lower end and the flange platform of the retreat stop block on the outer wall of the retaining cylinder
The circular-hole internal-wall of rank is connected, and is provided with buckling groove in the retaining cylinder, the tubulose connection valve, flange step, connection circle,
Retaining cylinder and retreat stop block integrated injection molding.
Preferably, the outer wall of the tubulose connection valve is provided with some anti-skid bulges.
Preferably, the retreat stop block is flush with the height of retaining cylinder.
Beneficial effect using above technical scheme is：A kind of anti-blocking fast knot of suction nozzle diaphragm seal of the utility model structure
Structure, by setting up three retreat stop blocks on retaining cylinder, the Gask-O-Seal so allowed in suction nozzle will not under pneumatic pressure, along
Retreat stop block rises, so as to block the circular hole that tubulose connects valve, it is ensured that will not allow induction installation failure below.
Brief description of the drawings

Specific embodiment
Describe preferred embodiment of the present utility model in detail below in conjunction with the accompanying drawings.
Fig. 1, Fig. 2 and Fig. 3 show specific embodiment of the present utility model：A kind of anti-blocking fast knot structure of suction nozzle diaphragm seal,
Including suction nozzle body, the suction nozzle body includes tubulose connection valve 1, flange step 2, connection circle 3 and retaining cylinder 4,
The flange step 2 is arranged between tubulose connection valve 1 and connection circle 3, is provided with the middle of the flange step 2 and is connected with tubulose
The circular hole 5 of the internal diameter casing of valve 1, is uniformly provided with three retreat stop blocks 6, under the retreat stop block 6 on the outer wall of the retaining cylinder 4
End is connected with the inwall of circular hole 5 of flange step 2, is provided with buckling groove 7 in the retaining cylinder 4, the tubulose connect valve 1,
Flange step 2, connection circle 3, retaining cylinder 4 and the integrated injection molding of retreat stop block 6.
In the present embodiment, the outer wall of the tubulose connection valve 1 is provided with some anti-skid bulges 8, when tracheae is connected not
Easily come off because of air pressure.
In the present embodiment, the retreat stop block 6 is flush with the height of retaining cylinder 4, it is ensured that Gask-O-Seal will not be in gas
Pressure rises along retaining cylinder 4.
Based on above-mentioned：The anti-blocking fast knot structure of a kind of suction nozzle diaphragm seal of the utility model structure, by retaining cylinder 4
Three retreat stop blocks 6 are set up, the Gask-O-Seal so allowed in suction nozzle will not rise along retreat stop block 6 under pneumatic pressure, so that stifled
The circular hole 5 that tubulose connects valve 1 is lived, it is ensured that will not allow induction installation failure below.
Above-described is only preferred embodiment of the present utility model, it is noted that for the ordinary skill of this area
For personnel, on the premise of the utility model creation design is not departed from, various modifications and improvements can be made, these all belong to
In protection domain of the present utility model.
