The purpose of this utility model is to provide a kind of pipeline air-inlet seal arrangement, and the structural design of this pipeline air-inlet seal arrangement can solve the problem that in conduit component testing process, its mouthful of end connection sealing is poor effectively.
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technological scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1-Fig. 5, the pipeline air-inlet seal arrangement that the utility model embodiment provides comprises encircles part 1, seal ring 2 and gas-tpe fitting 3, wherein encircle part 1 and there is through hole, the through hole encircling part 1 is shoulder hole, this shoulder hole comprises the first hole 11 and the second hole 12 of the axial arranging along shoulder hole, and the aperture in the first hole 11 is greater than the aperture in the second hole 12.Seal ring 2 is arranged in the first hole 11, and seal ring 2 is positioned at the end near the second hole 12 in the first hole 11, and seal ring 2 abuts with the end wall in the second hole 12.Namely seal ring 2 is positioned at the joint in the first hole 11 and the second hole 12 and abuts with the stepped wall of shoulder hole.Gas-tpe fitting 3 is fixedly connected with the end part seal away from the first hole 11 in the second hole 12.Wherein, the through hole of seal ring 2 all should be communicated with the second hole 12 with the second hole 12, and the vent of gas-tpe fitting 3 is communicated with the second hole 12.
During the pipeline air-inlet seal arrangement that application the utility model embodiment provides, first the pipeline opening of UUT 4 being stretched into encircles in the first hole 11 of part 1, and the seal ring 2 in the pipeline opening of UUT 4 and the first hole 11 is offseted, now seal ring 2 is sandwiched between the pipeline opening of stepped wall and UUT 4, namely make the pipeline opening of UUT 4 closely abut with seal ring 2, the sealing reached between seal ring 2 and the pipeline opening of UUT 4 contacts.Now the pipeline of UUT 4 is all communicated with the vent of gas-tpe fitting 3 with the second hole 12, then inflated in gas-tpe fitting 3 by inflator, gas and then enter in the pipeline of UUT 4 by gas-tpe fitting 3 and the second hole 12, so carry out seal ring 2 in gas replenishment process closely to abut with the pipeline opening of UUT 4 all the time, to ensure that in UUT 4 pipeline in gas replenishment process with this, being tightly connected of the pipeline opening of UUT 4, gas can not leak from the pipeline opening of UUT 4, and then avoid the leak detection result affecting conduit component, improve the precision of detecting leak gas of conduit component.
Preferably, seal ring 2 is rubber seal, can ensure higher sealing when rubber seal and UUT 4 close contact.Certainly, seal ring 2 can also be resin seal circle, in this no limit.
Encircling part 1 can be metalwork or working of plastics etc., and the outer wall encircling part 1 can be column, and the first hole 11 and the second hole 12 are circular hole.In addition, the aperture encircling the first hole of part should be closed with the diameter compatible of the pipeline of UUT, encircles the diameter of aperture slightly larger than the pipeline of UUT in the first hole of part.
For the ease of making pipeline opening and seal ring 2 close contact of UUT 4, the drive unit 6 driving and encircle part 1 and move back and forth can also be comprised, so UUT 4 can be placed in suitable position and make the pipeline opening of UUT 4 relative with the first hole 11 of the first environmental protection part, then encircle part 1 by drive unit 6 driving to move to the direction near UUT 4, until the pipeline opening of UUT 4 to stretch in the first hole 11 encircling part 1 and with seal ring 2 close contact, then inflate, encircle part 1 by drive unit 6 driving again after detection to move to the direction away from UUT 4.The volume of general UUT 4 is comparatively large, and what so then avoid mobile UUT 4 and direct mobile small volume encircles part 1, accordingly convenient operation more.
Further, drive unit 6 can be cylinder, and cylinder more convenient operation controls.Certainly, drive unit 6 can also be linear electric motor or turbine and worm structure etc.
For the ease of drive unit 6 with encircle being fixedly connected with between part 1, also comprise and the output terminal of drive unit 6 and the fixed plate 5 encircled part 1 and be all fixedly connected with, namely the output terminal of drive unit 6 drives fixed plate 5 to stretch, and then fixed plate 5 drives and encircles part 1 and move, so can make drive unit 6 and the connection of encircling between part 1 more firm.
Further, fixed plate 5 with encircle part 1 and can be bolted to connection.Can all offer multiple tapped hole on the outer wall encircling part 1 He on fixed plate 5 particularly, bolt is threaded with multiple tapped hole.The axis of bolt can be arranged with the axis being parallel of the shoulder hole encircling part 1, in this no limit.
In addition, for the ease of installing fixed drive device 6, the mounting plate 7 be fixedly connected with drive unit 6 can also be comprised, so direct by fixing for mounting plate 7 in place.Further, can to comprise the first plate be fixedly connected with drive unit 6 and the second plate 72, first plate 71 be fixedly connected with the first plate mutually vertical with the second plate 72 for mounting plate 7.So more save the installing space of drive unit 6.
The vent of gas-tpe fitting 3 can comprise and being interconnected and the first paragraph 31 of axes normal and second segment 32, is so more convenient to inflator and is connected with gas-tpe fitting 3.Wherein one end of gas-tpe fitting 3 can be relative with the second plate, and offer through hole on the second plate, passes through hole be connected with gas-tpe fitting 3 to make inflator.
It should be noted that, the pipeline opening for the ease of UUT 4 stretches into encircles in the first hole 11 of part 1, and wherein the end away from the second hole 12 in the first hole 11 is horn mouth, and horn mouth reduces gradually along the aperture, direction near the second hole 12.
Screw thread fixed seal connection can be passed through in the end in gas-tpe fitting 3 and the second hole 12, all right seal welding in end in certain gas-tpe fitting 3 and the second hole 12, in this no limit.
Preferably, two set of tubes air inlet seal arrangements can be used when inflating UUT 4 to be connected with two pipeline opening fitted seal of UUT 4 respectively, to improve the precision of detecting leak gas of conduit component further.
In this specification, each embodiment adopts the mode of going forward one by one to describe, and what each embodiment stressed is the difference with other embodiments, between each embodiment identical similar portion mutually see.
