Description
Technical field
The utility model relates to a kind of transmitter, and particularly, relating to can from the pressure unit of pressure release when a kind of pressure overload is revealed.
Background technology
At present, known pressure unit overvoltage protection structure is all be made on pressure transducer, relies on and be threaded between sensor with pressure unit, not any isolation in connection procedure.And pressure transducer can be divided into metal mold and non-metal type according to material and characteristic.The principle of work of metal mold and non-metal type sensor is all the structure adopting voltage dependent resistor (VDR) bridge, and the resistance of voltage dependent resistor (VDR) changes along with the change of pressure, the change produced is exported by lead-in wire.So when pressure overload, measured medium can damage pressure transducer, pressure unit is entered from the path of lead-in wire, pressure unit internal pressure is caused to increase, damage link cover of FIG, endoscopy glass, there is glass chip or link cover of FIG splashing, to installation and the environment for use generation threat of pressure unit.
Utility model content
For defect of the prior art, the purpose of this utility model is to provide can from the pressure unit of pressure release when a kind of pressure overload is revealed, it avoids because pressure unit pressure overload occurs damaged, avoids pressure unit owing to transshipping the threat of breaking and producing environment.
According to an aspect of the present utility model, can from the pressure unit of pressure release when providing a kind of pressure overload to reveal, it is characterized in that, comprise pressure transducer, division board, terminal block, link cover of FIG, sealing gasket, display, visor lid, endoscopy glass, pressure unit housing, macromolecule plug, relief hole, pressure transducer is connected with one end of pressure unit housing, the other end of link cover of FIG is connected with the other end of pressure unit housing, terminal block is between link cover of FIG and sealing gasket, sealing gasket is positioned at the side of division board, link cover of FIG is connected with the rear end of pressure unit housing, endoscopy glass is connected with the front end of pressure unit housing, display, visor lid is all positioned at the side of endoscopy glass, macromolecule plug and relief hole interference fit, relief hole is positioned at the side of pressure unit housing on the surface.
Preferably, the outside of described relief hole is provided with O type circle.
Preferably, the other end of described pressure unit housing is provided with wiring plug.
Preferably, the outer face of described macromolecule plug flushes with the surface of pressure unit housing.
Compared with prior art; the utility model has following beneficial effect: the utility model can when pressure unit damages due to pressure overload; avoid it because self breakage is to surrounding environment generation threat; namely the utility model is when pressure overload leaks; macromolecule plug is due to external and internal pressure difference change meeting Automatic-falling; equalized pressure sensor external and internal pressure is poor, prevents pressure unit from causing detachable block to splash because of damage, protects installation and environment for use.
Accompanying drawing explanation
By reading the detailed description done non-limiting example with reference to the following drawings, other features, objects and advantages of the present utility model will become more obvious:
Can from the structural representation of the pressure unit of pressure release when Fig. 1 is the leakage of the utility model pressure overload.
Can from the front view of the pressure unit of pressure release when Fig. 2 is the leakage of the utility model pressure overload.
Embodiment
Below in conjunction with specific embodiment, the utility model is described in detail.Following examples will contribute to those skilled in the art and understand the utility model further, but not limit the utility model in any form.It should be pointed out that to those skilled in the art, without departing from the concept of the premise utility, some distortion and improvement can also be made.These all belong to protection domain of the present utility model.
As depicted in figs. 1 and 2, the utility model pressure overload can comprise pressure transducer 1 from the pressure unit of pressure release when revealing, division board 2, terminal block 3, link cover of FIG 4, sealing gasket 6, display 7, visor lid 8, endoscopy glass 9, pressure unit housing 10, macromolecule plug 12, relief hole 13, pressure transducer 1 is connected with one end of pressure unit housing 10, the other end of link cover of FIG 4 is connected with the other end of pressure unit housing 10, terminal block 3 is between link cover of FIG 4 and sealing gasket 6, sealing gasket 6 is positioned at the side of division board 2, link cover of FIG 4 is connected with the rear end of pressure unit housing 1, endoscopy glass 9 is connected with the front end of pressure unit housing 1, display 7, visor lid 8 is all positioned at the side of endoscopy glass 9, macromolecule plug 12 and relief hole 13 interference fit, relief hole 13 is positioned at the side of pressure unit housing 10 on the surface.
The outside of relief hole 13 is provided with O type circle 5, plays sealing function.
The other end of pressure unit housing 10 is provided with wiring plug 11, plays sealing function.
The outer face of macromolecule plug flushes with the surface of pressure unit housing, plays the effect of interference fit.
Angle between relief hole 13 and vertical direction is 65 degree, and such pressure release effect is best.
The utility model increases relief hole at the lower right-hand side of pressure unit installation direction.Pressure unit is entered in order to prevent outside liquid, use the macromolecule plug of waterproof and breathable, by macromolecule plug and relief hole interference fit, ensure that macromolecule plug can not come off from pressure unit in transport, installation, use procedure, effectively prevent outside splashing liquid to enter damage instrument from relief hole simultaneously.And when pressure unit pressure overload; pressure unit internal pressure can discharge from relief hole; balance external and internal pressure is poor; thus the detachable block that pressure unit assembles is protected; namely avoid because pressure unit pressure overload occurs damaged, avoid pressure unit owing to transshipping the threat of breaking and producing environment.
Pressure transducer is connected with pressure unit housing by screw thread, and on the right side of pressure unit housing internal threads, root increases a relief hole, and by macromolecule plug interference fit.Pressure unit enclosure interior is two independently spaces by division board and division board sealing gasket, when pressure unit overvoltage, because its inside is confined space, internal pressure kept increases, cause macromolecule plug cannot bear pressure to change and Automatic-falling, pressure unit internal pressure can discharge from relief hole.Pressure unit internal pressure can not continue to increase, thus protects link cover of FIG, visor lid, endoscopy glass, these detachable blocks of wiring plug, avoids the situation of its impaired splashing to occur, the installation of protection pressure unit and environment for use.
Above specific embodiment of the utility model is described.It is to be appreciated that the utility model is not limited to above-mentioned particular implementation, those skilled in the art can make various distortion or amendment within the scope of the claims, and this does not affect flesh and blood of the present utility model.
