Now need a kind of device to solve the problem for this reason.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of shunting selecting type pressure tester, and this device can select the tensimeter of suitable range to carry out the measurement of pressure according to the size of pressure, adds the accuracy of pressure measurement and can not damage tensimeter.
For solving the problem, the technical scheme that the utility model is taked is: this device comprises the inner housing with crossing gas passage, the leading flank of described housing is provided with two front ports, the trailing flank of described housing is provided with a rear port, the right flank of described housing is provided with a right interface, described front port, rear port and right interface are interconnected by the gas passage of crossing of enclosure interior, two front ports connect one end of the first stop valve and the second stop valve respectively, pressure release stop valve is connected with at right interface, the other end of described first stop valve is connected with the first tensimeter, the other end of described second stop valve is connected with the second tensimeter, described first manometric range is greater than the second manometric range, the female joint of band is connected with at rear port place.
Preferably, the cross section of described housing is rectangle, the length direction of described gas passage is excessively identical with the length direction of housing, described rear port is communicated with the medium position crossing gas passage, two described front ports are connected with the both sides crossing gas passage respectively, and described right interface is communicated with the right-hand member crossing gas passage.
Preferably, described first stop valve with between front port, described second stop valve with between front port, described pressure release stop valve with between right interface, described joint is threaded with being between rear port.
The beneficial effect adopting technique scheme to produce is: compared with existing pressure vessel only having a kind of tensimeter mounting means of range, this device can bear pressure condition according to pressure vessel is actual, select the tensimeter being applicable to range at any time, open corresponding control stop valve, read true pressure value, do not damage tensimeter because pressure gage measuring range is too small relative to true pressure value, also can not make read untrue because manometric range is excessive.
