钛合金压力表
SPECIAL PRESSURE GAUGE
用途　USE
    钛压力表适用于测量对钛合金不起腐蚀作用的强腐蚀性介质的压力.
    As made from Ti-alloys,the gauge is applicable to pressure measurement for highly corrosive mediums which should be noncorrodible to Ti - alloys.
结构与原理
钛压力表是由测量系统(包括接头,弹簧管,齿轮传动机构),指标系统(指针,度盘),表壳部分组成.接头和弹簧管是用特殊金属-钛制成,耐 腐蚀性强,故此仪表可测量强腐蚀性介质的压力.其工作原理是基于弹性元件弹簧管变形.当被测介质由接头进入弹簧管,使弹簧管自由端产 生位移.此位移借助连杆,经齿轮传动机构的压力传递和放大,使指针在度盘上指示出压力.
此仪表的结构型式为I型(径向)和II型(径向后带边).
The special gauge is composed of three parts: the measuring system includign joint, Bourdon tube and gear drive; the indicator including pointer and dial; the casing. It is featured by that both the Joint and Bourdon tube are made from Ti-alloy with high corrosion - resistance, so is applicable to pressure measurement for highly corrosive mediums. Based on the deformation of Bourdon tube, an elastic element,the gauge will be brought into effect as the medium to be measured enters into Bourdon tube through joint, then a displacement takes place at the end of the Bourdon tube. The displece-ment will further be transmitted and amplified by means of connecting rod and gear drive, and the pointer indicates the value of pressure on dial.
Types I and II are both suppliable: the axial and the axial with rear flange, respectively.
