Embodiment
Lift preferred embodiment below, and come by reference to the accompanying drawings clearlyer intactly the utility model to be described.
Embodiment
Understood incorporated by reference to Fig. 1, a kind of special joint for air-tightness detection device, comprised a three-way pipe 1, bipass 2 (can be all metal tube).Three-way pipe 1 has first conduit 11, center tube 12 and second conduit 13.One end of first conduit 11 is connected with one end of the second conduit 13.The tube wall of the second conduit 13 offers a through hole, and by this through hole, center tube 12 is connected with the second conduit 13.Bipass 2 comprises a top duct 21 and bottom conduit 22, and top duct 21 entirety is in wedge shape.One end and the top duct 21 of center tube 12 are tightly connected.The outer wall of the first conduit 11 has screw thread, and this screw thread matches with the gas port of the high-pressure air pipe for providing power.
Understood incorporated by reference to Fig. 2, center tube 12 comprise one in the middle part of connecting pipe 121, center contact 122, one end of middle part connecting pipe 121 is connected with the second conduit 13, and the other end of middle part connecting pipe 121 is connected with center contact 122.
Understood incorporated by reference to Fig. 2, Fig. 3, top duct 21 has top interface 211, wedge guide 212, one end of top interface 211 is communicated with the top of wedge guide 212, the diameter of top interface 211 is less than the diameter on the top of wedge guide 212, the diameter on the top of wedge guide 212 is less than the diameter of the bottom of wedge guide 212, and the other end and the center contact 122 of top interface 211 match.The bottom of wedge guide 212 is connected with bottom conduit 22, and the diameter of the bottom of wedge guide 212 is greater than the diameter of bottom conduit 22.The outer wall of bottom conduit 22 has screw thread and to match nut with described screw thread.In order to play better sealing effectiveness, can the sheathed packing washer of outer wall of top interface 211.The sheathed packing washer of outer wall of bottom conduit 22, packing washer is between the bottom and nut of wedge guide 212.
Understood incorporated by reference to Fig. 1, Fig. 3, during use, be threaded between the gas port of high-pressure air pipe with the first conduit 11, by bottom conduit 22 through the bleeding point on air-tightness detection device until the bottom of wedge guide 212 is resisted against on bleeding point, nut is screwed from bottom to top along bottom conduit 22, the bleeding point of special joint and air-tightness detection device is fixed.Start high-pressure air pipe, after high pressure draught (pressure is 0.6MPa) is blown into and enters air-tightness detection device from the first conduit 11 along center tube 12, to flow out along center tube 12 rapidly again, discharge from the second conduit 13, in air-tightness detection device, form the air-flow of a circulation, make to form vacuum state in air-tightness detection device, and under external atmospheric pressure effect, firmly be adsorbed on position to be detected, so that externally the impermeability of detection part detects.After detection completes, the second conduit 13 can be blocked, now, because the first conduit 11 is still in air inlet, gas pressure intensity in special joint is raised gradually, eventually exceeds atmospheric pressure, make not need effort just air-tightness detection device can be taken away from position to be detected.Whole operating process is convenient, fast, does not need operating personnel to expend larger muscle power.And due on air-tightness detection device perforate less, make the strength-enhanced of air-tightness detection device, serviceable life increase, reduce the production cost of enterprise.
Although the foregoing describe embodiment of the present utility model, it will be understood by those of skill in the art that these only illustrate, protection domain of the present utility model is defined by the appended claims.Those skilled in the art, under the prerequisite not deviating from principle of the present utility model and essence, can make various changes or modifications to these embodiments, but these change and amendment all falls into protection domain of the present utility model.
