Abstract
The utility model relates to a corrosion prevention pressure transducer, which is used for measuring the pressure of corrosion mediums with easy crystallization and easy scale formation. The corrosion prevention pressure transducer is made into by improvement on the base of the structure of the existing corrugated tube type corrosion prevention pressure transducers. The elastic membrane made from corrosion prevention material polytetrafluoroethylene is adopted to replace the elastic corrugated tubes, then the elastic membrane and the lining are assembled in a shell body and a socket sleeve by utilizing the sealed technology, and the cavity formed between the shell body and the elastic membrane is made to be filled with pressure transmitting medium oil. The pressure of the measured corrosion medium is passed to a pressure gauge through the elastic membrane and the pressure transmitting medium oil, and the pressure value is accurately indicated out.
Description
The utility model provides a kind of pressure transducer, especially for the corrosion pressure sensor of the corrosion medium pressure of measuring easy crystallization, easy fouling.
The present inventor is once at the existing spring-tube type table of anti-ammonia, stainless steel watch, diaphragm barrier film table, the structure of anticorrosion tensimeter watch cores such as molybdenum 2 titanium tables, resistance to corrosion is low, fragile, the defective that serviceable life is short, design a kind of corrosion pressure sensor, its patent No. is No. 44 bulletins of CN88210181(utility model patent communique 4 volumes), can make general purpose pressure gauge be used to measure the pressure of corrosive medium, overcome above-mentioned defective.But this elastic corrugated tubular type pressure transducer is mainly used in clean corrosive medium.For easy crystallization, easily fouling, dirtier corrosive medium, the accuracy of its pressure transmission value tends to be affected.Therefore,,, must be improved, otherwise will be influenced the accuracy of measuring at the corrosion medium pressure that is used to measure non-cleaning to existing bellows-type pressure transducer.
The purpose of this utility model provides a kind of improved corrosion pressure sensor, and it is specially adapted to measure easy crystallization, easily fouling, dirtier corrosion medium pressure, its value accurately, reliable.
The purpose of this utility model is achieved in that this device is improved to make on the basis of existing bellows-type corrosion pressure sensor structure.Adopt the anti-corrosion material teflon to make flexible sheet and replace elastic bellows, utilize sealing technology that flexible sheet and lining are assembled in housing and the cover for seat then, make the cavity that forms between housing and the flexible sheet be full of pressure transmitting medium oil, the gasket end flange is pressed in the cover for seat end face.When tested unholiness corrosive medium enters cavity between lining and flexible sheet, cavity pressure makes flexible sheet produce deformation, cause that the pressure in the pressure transmitting medium oil pocket changes, the tensimeter that communicates and utilize sealing gasket and housing to fuse with the pressure transmitting medium chamber, the pressure transmission value is indicated, and this value promptly is the force value of tested corrosive medium.
Because adopting the corrosion-resistant teflon to make flexible sheet, the utility model replaces elastic bellows, so flexible sheet and be assembled in and form big cavity between the lining in the cover for seat, foul in the tested corrosive medium, crystal, foulant accumulate in the cavity, do not influence the deformation sensitivity of flexible sheet, therefore can guarantee the accurate, reliable of pressure transmission value effectively.
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is a kind of concrete structure cut-open view of the utility model.
Describe concrete structure of the present utility model and working condition with reference to the accompanying drawings in detail.These device case 4 upper ends fuse by sealing gasket 7 and general purpose pressure gauge 6.In cover for seat 2, assemble the lining 1 that teflon is made in advance, and make lining 1 end 10 flange be pressed in cover for seat 2 end faces.The flexible sheet 3 that adopts teflon to make is put into housing 4, the position that flexible sheet 3 peripheries contact with lining 1 is shaped on back-up coat, by screw thread 8 cover for seat 2 is tightened in the housing 4, compress flexible sheet 3, utilize the roll riveting sealing technology to make it to fit together again, make the bigger cavity of formation between flexible sheet 3 and the lining 1.Like this, when tested corrosive medium enters this cavity, all be the corrosion-resistant teflon owing to what contact with it, so have good resistance to corrosion.Simultaneously, the cavity that forms between flexible sheet 3 and housing 4 communicates with the core pipe of general purpose pressure gauge 6, adopts specialized apparatus, makes cavity and core pipe be full of pressure transmitting medium oil 5, and makes the pressure of tensimeter 6 be designated as zero.Because of tested corrosive medium does not directly contact with pressure watch core pipe, thus not only can adopt general purpose pressure gauge, but also can prolong manometric serviceable life.
During pressure measurement, this device is tightened on the container of tested corrosive medium by the flat side 9 on the cover for seat 2, tested corrosion medium pressure P passes to the cavity of 1 of flexible sheet 3 and lining, make flexible sheet 3 that deformation take place, by pressure transmitting medium oil 5 pressure P is passed to tensimeter 6, the pressure transmission value is indicated exactly.
Claims (2)
1, a kind of corrosion pressure sensor, it comprises the tensimeter that fuses by sealing gasket and housing, the lining that adopts teflon to make is assembled in the cover for seat, it is characterized in that adopting teflon to make flexible sheet, utilize sealing technology that flexible sheet and lining are assembled in housing and the cover for seat, make the cavity that forms between housing and the flexible sheet be full of pressure transmitting medium oil, the gasket end flange is pressed in the cover for seat end face.
2, sensor according to claim 1 is characterized in that the position that described flexible sheet periphery contacts with lining is shaped on back-up coat.
