Embodiment
Below in conjunction with specific embodiment, the present invention is described:
For through test specimen, in order to reach the object of carrying out pressurize detection, need to set up the cavity environment of a sealing.In the present embodiment, be exactly to adopt hydraulic pressure container to build the cavity environment of sealing, and when the detected pressures of tested through test specimen and dwell time are just in time identical, can detect simultaneously.Ring-like test specimen 8 in the present embodiment and the detected pressures of column type test specimen 13 are just in time identical with the dwell time, therefore can detect simultaneously, set up the cavity environment of sealing by hydraulic pressure container, ring-like test specimen, column type test specimen and various plug.
With reference to accompanying drawing 1, this device adopts high-pressure pump 1 that the high-pressure water that detects use is provided, and high-pressure pump is connected by pressure piping 2 with high pressure connection 3.Hydraulic pressure container 4 is core components of this device, and it is hollow cylindrical structure, the inner cavity that forms.In hydraulic pressure container one end, adopt small stair circle external thread face to be tightly connected with high pressure connection inner threaded surface, step center has through hole to pass into the cavity of hydraulic pressure container, forms water under high pressure passage, assurance not pressure release of water under high pressure and entering in hydraulic pressure container hollow cavity.
On the other end of hydraulic pressure container, have the groove and/or the hole that coordinate with through test specimen to be measured, for being sealedly and fixedly connected with through test specimen to be measured one end.Two through test specimens to be measured in the present embodiment are respectively ring-like test specimen 8 and column type test specimen 13, so have ring shaped slot and stepped hole on the other end of hydraulic pressure container.
The structural drawing of ring-like test specimen and column type test specimen is with reference to accompanying drawing 2 and accompanying drawing 3: ring-like test specimen is through rotary structure, and one end is radially cylindrical step surface screw thread, and large end face is inner groove structure, and center is step through-hole structure; The other end is also radially step disc, has three sealing through holes on large end face, and sealing through hole center is interior step through-hole structure.Column type test specimen is through rotary structure, and one end is radially cylindrical step surface screw thread, and large end face center is interior step fixing structure, and there are two sealing through holes seam step bottom surface, has a sealing through hole on large end face; The other end is also radially step disc, and center is interior step fixing structure.
Ring-like test specimen is connected with hydraulic pressure container ring shaped slot inner threaded surface by cylindrical step external thread face, and the perforation ring groove surface that ring-like test specimen O-ring seal 7 sealings realize hydraulic pressure container and ring-like test specimen forms continuous confining surface; Column type test specimen is connected with the seam internal thread of hydraulic pressure container stepped hole by its large cylindrical external threaded surface, and 14 sealings of column type test specimen O-ring seal realize hydraulic pressure container and through hole surface, column type test specimen middle part forms continuous confining surface.
In the present embodiment, the stepped hole of hydraulic pressure container is logical its center cavity directly, so after the stepped hole of column type test specimen and hydraulic pressure container is tightly connected, water under high pressure just directly enters to not pressure release the position that column type test specimen need detect; And in order to make water under high pressure enter ring-like test specimen, at the ring-like trench bottom of hydraulic pressure container and hydraulic pressure container, radially have hole and pass into hydraulic pressure container center cavity, make water under high pressure just directly enter to not pressure release the position that ring-like test specimen need detect.
In order to form the cavity environment of sealing, in the present embodiment, also adopt multiple plug that the hole of exposing on column type test specimen, ring-like test specimen and hydraulic pressure container is sealed.Various plugs are rotary structure, and one end is radially screw thread step circle, and the other end is four directions or hexagonal structure, and according to the aperture difference of shutoff, size is different.
The first plug 6 external threads are connected with hydraulic pressure container 4 radial directed hole internal threads, and the first plug O-ring seal is positioned in the seal groove in hydraulic pressure container 4 radial directed holes, has guaranteed that the water under high pressure that enters radial directed hole does not leak.The second plug 10 external threads are connected with sealing through hole internal thread in ring-like test specimen 8 annular grooves, and the second plug O-ring seal is positioned in the seal groove of ring-like test specimen 8 large end face annular groove seal bores.The 3rd plug 12 external threads are connected with column type test specimen 13 large end faces and center stopping table terrace seal bore internal thread, and the 3rd plug O-ring seal 11 is positioned in the seal groove of column type test specimen 13 seal bores.
During detection, high-pressure pump is increased to hydraulic pressure the rated pressure needing gradually, and keeps pressure constant.Water under high pressure, under the effect of pump pressure, is injected in hydraulic pressure container hollow cavity by high-pressure water pipe and high pressure connection, and under the guiding of bullport and center pit platform, entering into ring-like test specimen, column type test specimen needs pressure-bearing to detect position.After voltage stabilizing certain hour, detect ring-like test specimen, whether column type test specimen there is leakage, the phenomenons such as distortion, destruction.After having tested, control high-pressure pump pressure release gradually, the WATER AS FLOW MEDIUM entering in airtight cavity along with the reduction of pump pressure is back to high-pressure pump water storage tank gradually by return pipe, completes test.Through continuous revision test, the pressurize that can complete whole test specimens detects.Due to special construction and the test specimen formation airtight cavity of this device by hydraulic pressure container, so can realize the pressurize detection that connects test specimen.
