When detecting ducted hydraulic pressure, the bar portion being threaded one end is loaded in pipe side wall, until body head is resisted against on pipeline.After fixing body, then enter with the head of pressure tester in the instrument connection in bar portion, and pressure tester head rear end adopt engagement thread be fixed in the connecting hole of body, and the degree of depth of connecting hole can limit pressure tester head insert excessively dark.When ducted water passes through the instrument connection in this body rod portion, the pick-up unit in instrument connection detects water flow pressure.For preventing ducted water due to the insertion of body, water is caused to flow out from sidewall and affect water-pressure survey, therefore, at the end arranged outside O-ring seal in bar portion.Water-pressure survey is achieved, easy disassembly by being simply threaded.
In above-mentioned pressure measurement plug, the end in described bar portion has guide part, has intilted spigot surface outside the end of described guide part, and described ring groove is opened in the outside of guide part.
In order to ensure the good situation that puts in place contacted against when installing with body, arrange guide part in end, this body rod portion, guide part enters in the through hole of pipe side and the front end of guide part and arranges spigot surface and make to be adjacent to pipe side, is more conducive to the accuracy of measuring.
In above-mentioned pressure measurement plug, the center of described guide part has inlet opening, and described inlet opening is connected with instrument connection, and the aperture of described instrument connection is greater than the aperture of inlet opening.
By the pick-up unit in the coupled logical instrument connection of uninterrupted test of inlet opening, judge ducted water flow pressure by the size on the water pressure gauge that pick-up unit is corresponding.
In above-mentioned pressure measurement plug, described bar portion outside screw number quantity is 4-6.Faster this body rod portion can be loaded in pipe side wall when mounted.
Compared with prior art, this pressure measurement plug has the following advantages:
1, when detecting ducted hydraulic pressure, be threaded connection and fix body, after fixing body, again pressure tester is arranged on body interior, be threaded connection on the connecting hole of body head, carrying out pressure measurement in the head of the pressure tester instrument connection in this body rod portion, achieving water-pressure survey, easy disassembly by being simply threaded.
2, in order to ensure the good situation that puts in place contacted against when installing with body, arrange guide part in end, this body rod portion, guide part enters in the through hole of pipe side and the front end of guide part and arranges spigot surface and make to be adjacent to pipe side, is more conducive to the accuracy of measuring.
3, in the center of guide part, there is inlet opening, by the pick-up unit in the coupled logical instrument connection of uninterrupted test of inlet opening, judge ducted water flow pressure by the size on the water pressure gauge that pick-up unit is corresponding.
Accompanying drawing explanation
Fig. 1 is the body front view of this pressure measurement plug;
Fig. 2 is the body cut-open view of this pressure measurement plug.
In figure, 1, body; 2, head; 3, bar portion; 4, connecting hole; 5, instrument connection; 6, ring groove; 7, O-ring seal; 8, guide part; 8a, spigot surface; 9, inlet opening.
Embodiment
Be below specific embodiment of the utility model and by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiments.
As depicted in figs. 1 and 2, this pressure measurement plug, comprise the body 1 with head 2 and bar portion 3, the cross section of body 1 is T-shaped, the head 2 of body 1 is outer-hexagonal head, head 2 center of body 1 inwardly offers connecting hole 4, the madial wall of connecting hole 4 has interior connecting thread, the bar portion 3 of body 1 offers instrument connection 5 in the axial direction, instrument connection 5 is connected with connecting hole 4, and the diameter of instrument connection 5 is less than the diameter of connecting hole 4, and the outside in bar portion 3 is provided with outer connecting thread, be provided with ring groove 6 outside the end in bar portion 3, in ring groove 6, be provided with O-ring seal 7.When detecting ducted hydraulic pressure, the bar portion 3 being threaded one end is loaded in pipe side wall, until body 1 head 2 is resisted against on pipeline.After fixing body 1, then enter in the instrument connection 5 in bar portion 3 with the head 2 of pressure tester, and pressure tester head 2 rear end adopts engagement thread to be fixed in the connecting hole 4 of body 1, and the degree of depth of connecting hole 4 can limit pressure tester head 2 inserts excessively dark.When ducted water passes through the instrument connection 5 in body 1 bar portion 3, the pick-up unit in instrument connection 5 detects water flow pressure.For preventing ducted water due to the insertion of body 1, water is caused to flow out from sidewall and affect water-pressure survey, therefore, at the end arranged outside O-ring seal 7 in bar portion 3.Water-pressure survey is achieved, easy disassembly by being simply threaded.
Say further, the end in body 1 bar portion 3 has guide part 8, the diameter of guide part 8 is less than threaded bar portion 3 diameter, there is outside the end of guide part 8 intilted spigot surface 8a, in order to ensure the good situation that puts in place contacted against when installing with body 1, arrange guide part 8 in end, body 1 bar portion 3, guide part 8 enters in the through hole of pipe side and the front end of guide part 8 and arranges spigot surface 8a and make to be adjacent to pipe side, is more conducive to the accuracy of measuring.
