Embodiment
For above-mentioned purpose of the present utility model, feature and advantage can be become apparent, below in conjunction with accompanying drawing embodiment of the present utility model is elaborated.At first need to prove, the utility model is not limited to following embodiment, those skilled in the art should understand the utility model from the spirit that following mode of execution embodies, and each technical term can be done the most wide in range understanding based on Spirit Essence of the present utility model.Same or analogous member uses the same reference numerals to represent among the figure.
Consult Fig. 2,3, the inside pipe fitting leak-proof gasket of the utility model the first preferred embodiment comprises a ring section 2, and two extensions 3.In the present embodiment, the material of this inside pipe fitting leak-proof gasket is rubber.
And extend towards two opposite directions from this ring section 2 respectively in the form of a ring described extension 3.
Each extension 3 comprises that the inner ring surface 32 of an outer ring surface 31, opposite this outer ring surface 31, two spacer ring windings place outer 33, two spacer ring windings of ring that recline of this outer ring surface 31 to place this outer ring surface 31 and are positioned at 34, the mounting grooves 35 that are positioned at this inner ring surface 32 of ring that recline of described outer 33 on the ring of reclining, and one is arranged at this outer ring surface 31 and is positioned at corresponding described 34 on the ring and be communicated with the perforation 36 of this mounting groove 35 of reclining.
The outer ring 33 that reclines of each of each extension 3 has first an extension section 331 that extends outwardly from this outer ring surface 31, and second an extension section 332 that is connected in a side of these the first extension section 331 opposite these outer ring surfaces 31.
Each second extension section 332 extends towards another the second extension section 332 of same extension 3 from this corresponding the first extension section 331, and the outer surface that each second extension section 332 extends towards another the second extension section 332 is to be close to gradually this outer ring surface 31.
The ring 34 that reclines in each has respectively first an interior extension part 341 that extends outwardly from this outer ring surface 31, and second an interior extension part 342 that is connected in a side of these first interior extension part 341 opposite these outer ring surfaces 31.
Each second interior extension part 342 is that another the second interior extension part 342 towards same extension 3 extends from this corresponding first interior extension part 341, and each second interior extension part 342 is to be close to gradually this outer ring surface 31 towards the outer surface that another second interior extension part 342 extends.
Consult Fig. 4,5,6, during use, this inside pipe fitting leak-proof gasket is arranged in the pipe fitting 41 with crack 411, and described extension 3 is arranged at respectively the both sides in crack 411, and in the fixed plate 42 of four annular space arrangements of each mounting groove 35 interior installation, after then with a frock appliance (not shown) fixed plate 42 in each mounting groove 35 being strutted and is butted on this extension 3, four support plates 43 are arranged at respectively 42 of two adjacent fixed plates in the same mounting groove 35 so that described fixed plate 42 is maintained at the state that is butted on this extension 3, be arranged at two adjacent fixed plates 42 in the same mounting groove 35 with four connecting sheets 44 respectively at last, to strengthen the position of fixing described fixed plate 42 and described support plate 43, just can make that described fixed plate 42 is stable to be strutted and from inboard described extension 3 is butted on this pipe fitting 41 inboards, and make 411 places, crack of this pipe fitting 41 reach the effect of leakproof.In the present embodiment, the crack 411 of indication pipe fitting 41 refers to the crack that produces on the surface of single pipe fitting 41, but also can refer in the mutual seam during serial connection of two pipe fittings 41.
Consult Fig. 3,5,7, when described extension 3 is pushed against and is butted on this pipe fitting 41 when inboard, because described the second extension section 332 and the described second interior extension part 342 of each extension 3 are relatively to extend separately, therefore can guarantee that the described second interior extension part 342 is pushed against and produces when being out of shape, can be towards same Direction distortion, and make described the first extension section 331, the described first interior extension part 341, distortion place of described the second extension section 332 and 41 extruding of 342 pairs of these pipe fittings of the described second interior extension part can be fitted closely, and then promotes the effect of leakproof.
After this pipe fitting 41 and this inside pipe fitting leak-proof gasket combination are complete, also can test in advance leak preventing effect first, as long as after one of them perforation 36 poured into gas, after making the above-mentioned gas of the interior space-filling of recline in described in the corresponding extension 3 ring 34 and corresponding this pipe fitting 41, whether the seam crossing that detects this pipe fitting 41 and this extension 3 has gas leakage, just can test in advance leak preventing effect, if and will test with liquid the time, as long as after same outer ring surface 31 arranges two perforations 36, just can pour into liquid to one of them perforation 36, this moment, another corresponding perforation 36 used as exhaust, when liquid complete and when overflowing in exhaust, seal this perforation 36 that uses as exhaust, and continued to pour into liquid so that fluid pressure arrives a presumptive test pressure by this perforation 36 that originally poured into liquid, just can by the seam crossing that detects this pipe fitting 41 and this extension 3 whether leakage liquid be arranged equally, and test in advance leak preventing effect.
In sum, the setting of the bearing of trend by the described second interior extension part 342 is so that the deformation direction of each second interior extension part 342 when being squeezed can be consistent, and then improve leak preventing effect, so really can reach the purpose of this utility model.
Should be understood that those skilled in the art can make various changes or modifications the utility model after having read above-mentioned instruction content of the present utility model, these equivalent form of values fall within the application's appended claims limited range equally.
