Description
Technical field
The utility model relates to electronic applications, is specifically related to a kind of pressure-adjusting type hydraulic pressure transducer.
Background technology
Hydraulic sensing is applicable to various weight and pressure survey.The most bare bones of hydraulic pressure transducer has oil cylinder, main valve body, piston, seal, cylinder cap, means of deflation and sensor 6 parts.
But, there is the sordid problem of venting in the existing hydraulic pressure transducer in market, and when combinationally using to this multiple hydraulic pressure transducer owing to not having pressure regulation device, cannot ensure that the precompressed of each hydraulic pressure transducer is identical, pressure-adjusting type hydraulic pressure transducer designs for this situation just.
Utility model content
The purpose of this utility model is to provide a kind of pressure-adjusting type hydraulic pressure transducer, the sordid problem of venting existed with the hydraulic pressure transducer solving prior art.
For achieving the above object, the utility model provides a kind of pressure-adjusting type hydraulic pressure transducer, comprise in oil cylinder, oil cylinder be provided with main valve body, between main valve body and oil cylinder, be provided with piston, sensor setting is outside at oil cylinder, passage is provided with below it, below UNICOM to described main valve body, there is the dip plane of inside inclined upward, the top end opening UNICOM inclination oil duct of this dip plane bottom described main valve body, this inclination oil duct top is connected with housing screw, is provided with a ball below this housing screw.
Preferably, the pressure-adjusting type hydraulic pressure transducer that the utility model provides also comprises regulator, and described regulator comprises adjusting bolt and nut further, and described adjusting bolt is bolted in valve body, bottom this valve body UNICOM to oil cylinder, the afterbody of described valve body and described adjusting bolt is provided with O-ring seal.
Preferably, the pressure-adjusting type hydraulic pressure transducer that the utility model provides, the bottom of described main valve body is circular conical surface, and upwards, the bottom of gland nut is circular conical surface to the vertex of a cone, tightens circular conical surface that is rear and main valve body 7 and coincide, unscrew housing screw and reach degassing.
The pressure-adjusting type hydraulic pressure transducer that the utility model provides, has means of deflation and regulator.In use, need not dismantle this sensor and just can carry out exitting and adjusting pressure, compare with other sensor, venting is clean, and pressure regulation is flexible, highly sensitive.Particularly multiple stage sensor is in parallel when using together, and each sensor can be adjusted to same original pressure, is convenient to control and accurately control output signal, makes measurement more accurate.
Accompanying drawing explanation
The structural drawing of the pressure-adjusting type hydraulic pressure transducer that Fig. 1 provides for the utility model.
Embodiment
Below by drawings and Examples, the technical solution of the utility model is described in further detail.
As shown in Figure 1, the utility model provides a kind of pressure-adjusting type hydraulic pressure transducer, this kind of hydraulic sensing is applicable to various weight and pressure survey, it comprises oil cylinder 8, main valve body 7, piston 12, oil sealing 10 and sensor 9, main valve body 7 is provided with in oil cylinder 8, piston 12 and oil sealing 10 is provided with between main valve body 7 and oil cylinder 9, it is outside that sensor 9 is arranged on oil cylinder 8, passage is provided with below it, below UNICOM to described main valve body 7, there is bottom described main valve body 7 dip plane of inside inclined upward, the top end opening UNICOM inclination oil duct of this dip plane, this inclination oil duct top is connected with housing screw 6, a ball 5 is provided with below this housing screw 6.Preferably, have the circular conical surface of inside inclined upward bottom described main valve body 7, two circular conical surface kissings of gland nut 11 and main valve body 7 connect., the vertex of a cone upwards, the bottom of gland nut is circular conical surface, tightens circular conical surface that is rear and main valve body 7 and coincide, unscrew housing screw and reach degassing.
The pressure-adjusting type hydraulic pressure transducer that the utility model provides also comprises regulator, described regulator comprises adjusting bolt 1 and nut 2 further, described adjusting bolt 1 is bolted in valve body 3, and bottom this valve body 3 UNICOM to oil cylinder, the afterbody of described valve body 3 and described adjusting bolt 1 is provided with O-ring seal 4.
The bottom of gland nut 11 and main valve body 7 all adopts circular conical surface, and two circular conical surface kissings of gland nut 11 and main valve body 7 connect.The size that circular conical surface bottom main valve body 7 tilts is determined according to the tiltable degree of hydraulic pressure transducer, even if even if some tilts when therefore sensor is installed, also bubble in oil can be made to rest on the topmost of gradient, as long as unscrew housing screw 6, air in oil just can be made to back down ball 5 along inclination oil duct air is discharged.Until only stream oil and there is no a bubble time, tighten housing screw 6, compacting spin 5 and reach sealing.No matter main valve body 7 rests on any position, in-oil cylinder air all can be ensured to put totally.
In addition, the utility model is also provided with regulator, and it comprises adjusting bolt 1, nut 2, valve body 3 and O-ring seal 4; By sensor 9, the electric signal size shown by observation, unscrews nut 2, tightens or unscrew to regulate stud 1, makes valve body 4 advance or retreat, and make the precompression of sensor increase or reduce, the signal of now sensor display also becomes large or diminishes.If the signal of several sensor shown by after adjustment is the same, so the precompression of these sensors too.When identical sensor uses together, not only connect easy to adjust, and measurement is also accurate.
Pressure-adjusting type sensor, owing to there being micromatic setting, so the precompression of sensor can be turned down, can make main valve body 7 flexible movements like this, increases the susceptibility measured.
It should be noted last that, above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify to the technical solution of the utility model or equivalent replacement, and not depart from the spirit and scope of technical solutions of the utility model.
