Embodiment
Below in conjunction with specific embodiment the present invention is described:
For through test specimen, carry out the purpose that pressurize detects in order to reach, need set up the cavity environment of a sealing.Be exactly to adopt the hydraulic pressure container to make up the cavity environment of sealing in the present embodiment, and when the detected pressures of tested through test specimen is just in time identical with the dwell time, can detect simultaneously.Ring-like test specimen 8 in the present embodiment is just in time identical with the detected pressures of column type test specimen 13 and dwell time, therefore can detect simultaneously, sets 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 usefulness is provided, and high-pressure pump is connected through pressure piping 2 with high pressure connection 3.Hydraulic pressure container 4 is core components of this device, and it is a hollow cylindrical structure, the inner cavity that forms.Adopt small stair circle external thread face to be tightly connected with the high pressure connection inner threaded surface at hydraulic pressure container one end, the step center has through hole to feed the cavity of hydraulic pressure container, forms the water under high pressure passage, assurance not pressure release of water under high pressure and getting in the hydraulic pressure container hollow cavity.
On the other end of hydraulic pressure container, have the groove and/or the hole that cooperate with through test specimen to be measured, be used for being sealedly and fixedly connected with through test specimen one end to be measured.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 on the other end of hydraulic pressure container, have ring shaped slot and stepped hole.
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 an end radially is a cylindrical step surface screw thread, and large end face is the inner groove structure, and the center is the step through-hole structure; The other end is the step disc also radially, and three sealing through holes are arranged on the large end face, and sealing through hole center is interior step through-hole structure.The column type test specimen is through rotary structure, and an end radially is a cylindrical step surface screw thread, and the large end face center is interior step fixing structure, and there are two sealing through holes seam step bottom surface, and a sealing through hole is arranged on the large end face; The other end radially also is the step disc, and the center is interior step fixing structure.
Ring-like test specimen is connected with hydraulic pressure container ring shaped slot inner threaded surface through cylindrical step external thread face, and ring-like test specimen O-ring seal 7 sealings realize that the perforation ring groove surface of hydraulic pressure container and ring-like test specimen constitutes continuous confining surface; The column type test specimen is connected with the seam internal thread of hydraulic pressure container stepped hole through its big cylindrical external threaded surface, and 14 sealings of column type test specimen O-ring seal realize that hydraulic pressure container and through hole surface, column type test specimen middle part constitute continuous confining surface.
In the present embodiment, directly logical its center cavity of the stepped hole of hydraulic pressure container is so after the stepped hole of column type test specimen and hydraulic pressure container was tightly connected, water under high pressure just directly got into to not pressure release the position that the column type test specimen need detect; And, radially have hole feeding hydraulic pressure container center cavity at ring-like trench bottom of hydraulic pressure container and hydraulic pressure container in order to make water under high pressure get into ring-like test specimen, make water under high pressure just directly get into to not pressure release the position that ring-like test specimen need detect.
In order to constitute the cavity environment of sealing, also adopt multiple plug that the hole of exposing on column type test specimen, ring-like test specimen and the hydraulic pressure container is sealed in the present embodiment.Various plugs are rotary structure, and an end radially is the screw thread step circle, and the other end is four directions or hexagonal structure, and size is different according to the aperture difference of shutoff.
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, have guaranteed that the water under high pressure that gets into the radial directed hole does not leak.Second plug, 10 external threads are connected with the interior sealing of ring-like test specimen 8 annular grooves through hole internal thread, 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 the rated pressure that needs gradually with hydraulic pressure, and it is constant to keep-up pressure.Water under high pressure is injected in the hydraulic pressure container hollow cavity through high-pressure water pipe and high pressure connection under the effect of pump pressure, under the guiding of bullport and center pit platform, enters into ring-like test specimen, column type test specimen need pressure-bearing detection position.Behind the voltage stabilizing certain hour, detect ring-like test specimen, whether the column type test specimen exists leakage, phenomenons such as distortion, destruction.After test is accomplished, the pressure release gradually of control high-pressure pump, the WATER AS FLOW MEDIUM that gets in the airtight cavity along with the reduction of pump pressure is back to the high-pressure pump water storage tank gradually through return pipe, accomplishes test.Through continuous revision test, the pressurize that can accomplish whole test specimens detects.Because this device constitutes an airtight cavity by the special construction and the test specimen of hydraulic pressure container, detect so can realize the pressurize that connects test specimen.
