Description
Technical field
The utility model relates to a kind of tensimeter, relates in particular to a kind of bourdon gauges.
Background technology
Bourdon gauges be a kind of be the tensimeter of sensitive element with the bourdon tube, mainly be used for measuring do not have blast, non-crystallizable, the pressure that do not solidify and copper and copper alloy do not had liquid, gas or the steam of corrosive attack.
China's utility model patent 200920199780.1 discloses a kind of small spring hook gauge, and this small spring hook gauge comprises watchcase, bourdon tube, copper sleeve, linkage magnification system, and bourdon tube is welded on the copper sleeve; The pipe of guide pressure medium is a kapillary; Kapillary passes watchcase and is welded on the copper sleeve, and the guide hole that is communicated with kapillary and bourdon tube is arranged in the copper sleeve, and bourdon tube is connected with linkage magnification system; Wear position capillaceous on the watchcase on the limit of watchcase base plate; A cylinder is extended in this position in watchcase, cylindrical cavity and this cylinder interference fit are arranged on the copper sleeve, and linkage magnification system is installed on the copper sleeve.
Above-mentioned existing bourdon gauges has been simplified the brill system technology of copper sleeve sprocket hole and the mounting process of linkage magnification system and copper sleeve; Saved the use of copper material, but when concrete the use, had following defective: adopt straight hole guide pressure medium, the size of technology hole drill system is difficult to hold; Fabrication hole is too big; Then tensimeter gas leakage probability is bigger, and fabrication hole is too little, and copper sleeve is coupled to and causes plastic meter shell to break on the watchcase easily.
Summary of the invention
It is low and save the bourdon gauges that copper material uses that the utility model technical matters to be solved provides a kind of watchcase probability that breaks, leaks gas of avoiding.
The utility model solves the problems of the technologies described above the technical scheme that is adopted:
A kind of bourdon gauges comprises watchcase, table lid, indicating mechanism, bourdon tube and copper sleeve, and described copper sleeve is fixedly connected with watchcase; Described watchcase base plate center has been wholely set a connector, and described connector set inside has an interface channel; Be wholely set a boss on the described watchcase internal backplane, described boss is provided with a connecting hole; Described copper sleeve bottom is provided with a joint pin, is provided with an air admission hole in the described joint pin; Described joint pin matches with connecting hole, and the end face of described connecting hole and the end face of joint pin are provided with an O-ring seal; Described copper sleeve side is provided with groove, is provided with an air hole that is connected with air admission hole in the described groove; Described bourdon tube is installed in the groove; Described interface channel does not overlap with an inclined hole mutually with connecting hole and is communicated with.
Described boss is provided with reference column, and described copper sleeve is provided with pilot hole, and described pilot hole cooperates with reference column.
The position that described watchcase is provided with boss is equipped with screwing through hole, and screw passes described screwing through hole, is spirally connected with described copper sleeve.
Compared with prior art; The advantage of the utility model is: adopt inclined hole guide pressure medium; The size ratio of fabrication hole is easier to hold, and has so just reduced the breakage rate of watchcase, and makes the probability of tensimeter gas leakage reduce greatly; Thereby guaranteed the stability of tensimeter work, and the use of having saved copper material to a certain extent.
