For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.
[0033] The utility model provides a water pipe airtightness detection component and device, which are not only applicable to the airtightness detection of water pipes in automobile engines, but also applicable to the airtightness detection of other rigid water pipes. The device is based on this component and other components. Specifically, the water pipe airtightness detection device includes a first sealing component, a second sealing component, this component, and a control component for controlling the distance between the first sealing component and the second sealing component.
[0034] When detecting a rigid water pipe, one end can be in a blocked state and the other end is filled with water pressure; or water pressure is filled at both ends simultaneously. In this regard, the first sealing component and the second sealing component placed at both ends of the water pipe to be detected in the water pipe airtightness detection device can be of different structures or the same structure.
[0035] Among them, there are many implementation methods for the water pipe airtightness detection component:
[0036] Example 1: If the water pipe airtightness detection component realizes the sealing of the end of a rigid water pipe, referring to Figure 1 , it includes a sealing block 1 and a first airbag 12. A sealing groove 11 is provided on the sealing block 1; the first airbag 12 is placed in the sealing groove 11. With this structure, when the airbag is inflated, the end of the water pipe presses the airbag, and the airbag has a reaction force on its end, and the end of the water pipe can be sealed by using this reaction force.
[0037] Since the thickness of the end of the water pipe is relatively thin, directly contacting the airbag is extremely easy to break the airbag. For this reason, on the basis of this structure, a limiting column 13 is provided in the sealing groove 11. The first airbag 12 is annular and sleeved outside the limiting column 13, and a crimping ring 14 is also sleeved outside the limiting column 13. The crimping ring is used to increase the contact area with the airbag to improve the service life of the airbag. The setting of the limiting column 13 facilitates the installation of the crimping ring 14.
[0038] In order to improve the sealing airtightness and the adaptation range of the water pipe, generally the diameter of the sealing groove 11 is relatively large. For this reason, in order to facilitate the installation of the end of the water pipe, a crimping groove 141 for inserting the water pipe to be detected is provided on the crimping ring 14. In order to further improve the detection airtightness, a sealing ring, such as a rubber ring, can be provided in the crimping groove 141. The end of the water pipe presses on the sealing ring, and the airtightness is better.
[0039] Example 2: If the water pipe airtightness detection component realizes the filling of water pressure at the end of a rigid water pipe, referring to Figure 3, it includes a sealing block 1, a limiting post 13 and a first airbag 12. A sealing groove 11 is provided on the sealing block 1, the limiting post 13 is arranged in the sealing groove 11, and a water passing hole 131 with one end communicating with a pressurized water pipe 3 is arranged on the limiting post 13; the first airbag 12 is annular and sleeved outside the limiting post 13. With this structure, its sealing principle is the same as that of Example 1. By arranging the water passing hole 131 on the limiting post 13, after the water pipe is inserted on the limiting post 13, water passing and stamping can be achieved.
[0040] Based on the structure of any of the above examples, in order to further improve the detection airtightness, referring to Figure 2 , 4 , a second airbag 15 can also be provided. The second airbag 15 is placed between the bottom of the sealing groove 11 and the first airbag 12, and a spring 151 is arranged in the second airbag 15. By arranging a second airbag between the bottom of the sealing groove 11 and the first airbag 12, when the water pipe presses the first airbag and moves towards the bottom of the sealing groove 11, both the second airbag and the spring have a reaction force on it. Using this reaction force, its airtightness can be greatly enhanced.
[0041] In order to improve the service life of the airbag, a first slider 16 is arranged between the second airbag 15 and the first airbag 12. By adopting the first slider, the acting area of the spring and the first airbag is enhanced, and the local stress of the first airbag is reduced.
[0042] In this regard, based on the implementation structure of the above water pipe airtightness detection assembly, there are various implementation methods for its first sealing assembly and second sealing assembly. Specifically, both the first sealing assembly and the second sealing assembly are a kind of water pipe airtightness detection assembly in Example 2 and any of its optimized structures. At this time, water pressure can be simultaneously applied to both ends of the water pipe to be detected. Or, referring to Figure 5 , the first sealing assembly is a kind of water pipe airtightness detection assembly in Example 2 and any of its optimized structures, and the second sealing assembly is a kind of water pipe airtightness detection assembly in Example 1 and any of its optimized structures. At this time, one end of the water pipe to be detected can be blocked, and water pressure can be applied to the other end. The sealing grooves 11 of the first sealing assembly and the second sealing assembly are placed on the side close to each other.
[0043] There are many implementation methods for the control assembly. Exemplarily, referring to Figure 5 , 6As shown in FIGS. 7, the control assembly includes a guide rail 41, a second slider 42, a fastener 43, and a first adjusting screw 44. The second slider 42 is placed on the guide rail and can move along the guide rail 41; the fastener 43 includes a mounting portion and a locking projection 431 provided on the mounting portion and facing the guide rail 41; the first adjusting screw 44 is connected between the mounting portion and the second slider 42 to adjust the distance between the locking projection 431 and the guide rail 41. To facilitate the operation of the first adjusting screw 44, a first handle 441 can be fixed to the end of the first adjusting screw 44. By rotating the first adjusting screw 44, the distance between the locking projection 431 and the guide rail 41 can be adjusted. When the locking projection 431 is in close contact with the guide rail 41, the locking of the second slider relative to the guide rail can be achieved.
[0044] To improve the locking stability and the moving stability of the second slider, two guide rails 41 are provided and arranged in parallel. To facilitate the installation and fixation of the guide rails, the guide rails 41 are fixed to the bracket 6.
[0045] When the first adjusting screw 44 controls the movement of the fastener 43, to prevent the fastener 43 and the first adjusting screw 44 from rotating together, the mounting portion can be in the shape of a square strip, and one side can be directly attached to the bottom of the second slider 42. Alternatively, a corresponding limiting structure can be provided between the mounting portion and the second slider 42, or a guide groove can be provided on the guide rail 41, and the locking projection 431 can be stuck in the guide groove.
[0046] When adopting this structure, the water pipe airtightness detection assembly can be directly fixed on the second slider 42.
[0047] To enable the detection of special-shaped water pipes and improve the application range of the detection device, an adjusting assembly for adjusting the relative positions of the two sealing grooves 11 is further provided on the first sealing assembly and / or the second sealing assembly.
[0048] The adjusting assembly can be provided only on the first sealing assembly or the second sealing assembly, or can be provided on both sealing assemblies at the same time.
[0049] There are many ways to implement the adjusting assembly. For example, referring to Figure 5 , the adjusting assembly includes a second adjusting screw 51. One end of the second adjusting screw 51 is fixed with a second handle 52. The sealing block 1 is sleeved outside the second adjusting screw 51 and is connected to the second adjusting screw 51 through a threaded hole.
[0050] Using the above device, the diameter of the sealing groove 11 is larger than the outer diameter of the water pipe to be detected. When detecting the water pipe, unlock the fastener 43, push the second sliders of the two end control assemblies to adjust the distance between the first sealing assembly and the second sealing assembly to be greater than the length of the water pipe to be detected, and then lock the fastener 43 of the first sealing assembly. Insert one end of the water pipe to be detected into the sealing groove 11 of the first sealing assembly so that the first airbag seals the end of the water pipe.
[0051] Then, adjust the second adjusting screw 51 at the end of the second sealing assembly according to the shape of the water pipe. After aligning its sealing groove 11 with the other end of the water pipe to be detected, push the second sliding block 42 of the second sealing assembly towards one end of the first sealing assembly. When the other end of the water pipe to be detected is inserted into the sealing groove 11 of the second sealing assembly and cannot be pushed further with force, lock the fastener 43 at the end of the second sealing assembly. Then, the water pipe 3 can be pressurized with water for airtightness detection.
[0052] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
