Description

A kind of shunting selecting type pressure tester
Technical field
The utility model relates to device for pressure measurement technical field.
Background technology
At present, various pressure pipeline and pressure vessel are provided with the mechanical hook-up observing display pressure, generally be made up of stop valve, tensimeter, for the pressure pipeline and the pressure vessel that bear pressure transient, the tensimeter of installation high-voltage or low pressure range need be adjusted at any time.If the pressure gage measuring range installed is excessive, then the force value error read is larger; If the pressure gage measuring range installed is too small, then can damages tensimeter and real force value cannot be read.
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.

Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail: as shown in Figure 1, a kind of shunting selecting type pressure tester, this device comprises the inner housing 2 with crossing gas passage 1, the leading flank of described housing 2 is provided with two front ports 3, the trailing flank of described housing 2 is provided with a rear port 4, the right flank of described housing 2 is provided with a right interface 5, described front port 3, rear port 4 and right interface 5 are interconnected by the gas passage 1 of crossing of housing 2 inside, two front ports 3 connect one end of the first stop valve 6 and the second stop valve 7 respectively, pressure release stop valve 8 is connected with at right interface 5 place, the other end of described first stop valve 6 is connected with the first tensimeter 9, the other end of described second stop valve 7 is connected with the second tensimeter 10, the range of described first tensimeter 9 is greater than the range of the second tensimeter 10, the female joint 11 of band is connected with at rear port 4 place.
The cross section of housing 2 is rectangle, the length direction of described gas passage 1 is excessively identical with the length direction of housing 2, described rear port 4 is communicated with the medium position crossing gas passage 1, two described front ports 3 are connected with the both sides crossing gas passage 1 respectively, and described right interface 5 is communicated with the right-hand member crossing gas passage 1.
First stop valve 6 with between front port 3, described second stop valve 7 is threaded with being between front port 3, between described pressure release stop valve 8 with right interface 5, between described joint 11 with rear port 4.
The housing 2 of this device is respectively with front port 3, right interface 5 and rear port 4, front port 3 is connected two tensimeters by the first stop valve 6 with the second stop valve 7, i.e. the first tensimeter 9 and the second tensimeter 10, two manometric ranges one large one little, right interface 5 connects pressure release stop valve 8, for being exhausted when pressure is excessive, and rear port 4 is connected with joint 11, joint 11 one end is with external thread, joint 11 is connected with rear port 4 by external thread, joint 11 other end is also with internal thread, the effect of joint 11 is for being communicated with Pressure Vessel or pipeline with pressure, connected by internal thread, in the concrete process used, first by the joint 11 of this device and equipment connection with pressure, then the main control valve on equipment is opened, gas is entered by joint 11 to be in gas passage 1, now three stop valves are all in closed condition, first the first stop valve 6 is opened, first gas enter into the first tensimeter 9, observe the reading of the first tensimeter 9, if the force value of display is lower than 1/3 of pressure gage measuring range, then close the first stop valve 6, open the second stop valve 7 and read numerical value on the second tensimeter 10, if the force value of display is greater than 3/5 of pressure gage measuring range, then close the main control valve on equipment with pressure, open pressure release stop valve 8 and lay down pressure in gas passage 1, the tensimeter of the suitable range of dismounting and change again.
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.
