Description
Technical field
The utility model relates to pressure measurement technology field, particularly a kind of diaphragm manometer.
Background technology
Diaphragm manometer is as the one of mechanical compression table, its linear displacement be directly proportional to pressure as formation after elastic sensing element pressurized by convoluted diaphragm, amplified by movement and convert indicators turn amount to, contrast dial plate indicating value shows the pressure in institute's test tube road or airtight cavity.Because diaphragm manometer has, structure is simple, applicability strong, security high, is widely used in the industries such as oil, chemical industry, heating power, electric power.
As shown in Figure 1, traditional diaphragm manometer comprises upper connector 04, lower connector 02, convoluted diaphragm 01, transmission lever 03, cartridge assemblies 06, indicator 07 and dial plate 05, wherein convoluted diaphragm 01 is arranged between upper connector 04 and lower connector 02 by fastening bolt, wherein upper connector 04 lower surface and lower connector 02 upper surface are planar structure, convoluted diaphragm 01 periphery contacts with lower connector 02 with upper connector 04 respectively, wherein seal mineralization pressure by O-ring seal between convoluted diaphragm 01 and lower connector 02 and measure cavity, measured medium is connect for holding, transmission lever 03 is arranged on convoluted diaphragm 01, transmission lever 03 and cartridge assemblies 06 are in transmission connection, cartridge assemblies 06 is connected with indicator 07.Diaphragm manometer operationally, measured medium enters pressure survey cavity by lower connector 02 pressure guide hole, pressure medium change causes convoluted diaphragm 01 linear deformation, convoluted diaphragm 01 deformational displacement is delivered to cartridge assemblies 06 by transmission lever 03, by cartridge assemblies 06, displacement is converted to the anglec of rotation, indicator 07 is connected with cartridge assemblies 06, and rotated with along with pressure alteration by cartridge assemblies 06, indicator 07 reflects measured medium force value by dial plate 05.
But, because diaphragm manometer mainly measures the slight pressure lower than 0.16MPa, for indivedual industry particular/special requirement, in measuring process, diaphragm manometer needs to carry out the operation such as back flush, moise-heat sterilization, causes diaphragm manometer will tolerate the pressure of range 5 to 10 times.Lower surface due to upper connector is planar structure, causes diaphragm plasticity serious deformation when convoluted diaphragm 01 is impacted by range more than many times, convoluted diaphragm 01 mechanical property is changed and causes the permanent damage of product, cause the serviceable life of convoluted diaphragm 01 shorter.
Therefore, how extending the serviceable life of convoluted diaphragm, is those skilled in the art's technical matterss urgently to be resolved hurrily.

Embodiment
Core of the present utility model is to provide a kind of diaphragm manometer, and the serviceable life of the convoluted diaphragm of this diaphragm manometer extends.
In order to make those skilled in the art understand the technical solution of the utility model better, below in conjunction with drawings and embodiments, the utility model is described in further detail.
Please refer to Fig. 2, in a kind of embodiment, the diaphragm manometer that the utility model provides comprises upper connector 4, lower connector 2, convoluted diaphragm 1 and transmission lever 3, transmission lever 3 is arranged on convoluted diaphragm 1, convoluted diaphragm 1 surrounding abuts with upper connector 4 and lower connector 2 respectively, and namely convoluted diaphragm 1 upper surface side abuts with upper connector 4 and seals, and convoluted diaphragm 1 lower surface side abuts with lower connector 2 and seals, between convoluted diaphragm 1 and lower connector 2, mineralization pressure measures cavity, connects measured medium for holding.The lower surface of upper connector 4 is provided with the corrugated surface that can match with convoluted diaphragm 1 external waviness, namely can fit with the lower surface of upper connector 1 after convoluted diaphragm 1 bearing strain.Concrete, upper connector 4 and lower connector 2 are fixedly connected by welding.When processing the corrugated surface of upper connector 4, first convoluted diaphragm 1 being calculated, depicting the strain mode of convoluted diaphragm 1 at standard range, then utilizing machine-tooled method upper connector 4 to be processed into the curved surface calculated.Then according to original processing mode assembly and adjustment, the product of formation because its upper connector 4 epicoele is according to measuring and calculating Machining of Curved Surface, make convoluted diaphragm 1 bear exceed diaphragm design range pressure time, convoluted diaphragm 1 is close to the corrugated surface of upper connector 4.
