Background technology
The sensing element of high-temperature fusant pressure transducer of the prior art is all to utilize paster glue that strainometer is sticked on elastic body mostly, the sticking strength that is subject to glue is strong and reaction velocity lags behind and the impact of chance hot mastication, conventional high-temperature fusant pressure transducer exists zero stability not strong, response frequency is not high, the not high weak point of fatigue resistance, for this weak point, in prior art, also there is people to make bonding method into argon arc welding, if patent announcement number is the Chinese utility model patent of CN200972419Y, the technical scheme adopting is, in the rear end of metal capillary, pressure-sensitive head is installed, elastic body is installed in a pressure-sensitive rear end, strainometer is installed in elastic body rear end, described elastic body is welded on pressure-sensitive head with argon arc welding machine, pressure-sensitive head is welded on Connection Block with argon arc welding machine.Although the impact of glue has been avoided in this improvement, there is certain radiation in the argon arc welding adopting, and described kapillary, pressure-sensitive head, elastic body, Connection Block need to carry out argon arc welding successively in addition, and welding sequence is numerous and diverse, operation inconvenience.In sum, lack a kind of zero stability strong in prior art, response frequency is high, the high high-temperature fusant pressure transducer simultaneously easy to process of fatigue resistance.
Utility model content
The technical problems to be solved in the utility model is, provides a kind of zero stability strong, and response frequency is high, the high high-temperature fusant pressure transducer simultaneously easy to process of fatigue resistance.
For solving the problems of the technologies described above, the technical scheme that the utility model provides is: a kind of high-temperature fusant pressure transducer, and it comprises diaphragm, screw rod, shell, kapillary, pedestal, pressure detecting element and aerial plug-in unit; One end of screw rod is connected with diaphragm, and the other end is connected with shell, and described pedestal and pressure detecting element encapsulate in the enclosure, and aerial plug-in unit is arranged on shell and with pressure detecting element and is electrically connected; Described kapillary runs through screw rod diaphragm is communicated with pressure detecting element; In kapillary, be filled with the liquid for transmission of pressure; Described pressure detecting element is by the integrated formed structure of high temp glass powder sintering on elastic body by strain gauge; Described pressure detecting element and pedestal weld by argon arc welding machine.
Adopt after said structure, the utlity model has following advantage: sensing element is abandoned the traditional method of the strainometer that fastens with glue, strainometer is passed through to high temp glass powder sintering on elastic body, and two parts combine together, then by argon arc welding technology, elastic body are welded on pedestal.So, having solved conventional high-temperature fusant pressure transducer exists zero stability not strong, response frequency is not high, the not high weak point of fatigue resistance, process convenient than the structure in the documents of mentioning in background technology again, also avoid high-temperature fusant pressure transducer because volume is larger simultaneously, cannot enter agglomerating plant and carry out the problem of sintering.In sum, the utility model provides a kind of zero stability strong, and response frequency is high, the high high-temperature fusant pressure transducer simultaneously easy to process of fatigue resistance.
As preferably, described diaphragm and screw rod pass through laser welding packaging.The connected mode of laser bonding is solid and reliable, good stability.
As preferably, described kapillary is welded between diaphragm and pedestal.This structure can further improve stability capillaceous.
As improvement, between described pressure detecting element and kapillary, be provided with the chamber of the contact area for expanding liquid in kapillary and pressure detecting element.This structure can close the liquid of transmission of pressure and the pressure-sensitive face of pressure detecting element fully contacts, and makes pressure detecting element sensitiveer and accurate.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
By reference to the accompanying drawings 1 and accompanying drawing 2, a kind of high-temperature fusant pressure transducer, it comprises diaphragm 1, screw rod 2, shell 3, kapillary 4, pedestal 5, pressure detecting element 6 and aerial plug-in unit 7; One end of screw rod 2 is connected with diaphragm 1, and the other end is connected with shell 3, and described pedestal 5 and pressure detecting element 6 are encapsulated in shell 3, and aerial plug-in unit 7 is arranged on shell 3 and with pressure detecting element 6 and is electrically connected; Described kapillary 4 runs through screw rod 2 diaphragm 1 is communicated with pressure detecting element 6; In kapillary 4, be filled with the liquid for transmission of pressure; Described pressure detecting element 6 is by the integrated formed structure of high temp glass powder sintering on elastic body by strain gauge; Described pressure detecting element 6 welds by argon arc welding machine with pedestal 5.Described diaphragm 1 passes through laser welding packaging with screw rod 2.Described kapillary 4 is welded between diaphragm 1 and pedestal 5.Between described pressure detecting element 6 and kapillary 4, be provided with the chamber 9 of the contact area for expanding liquid in kapillary 4 and pressure detecting element 6.
