Every other embodiment obtained, fall within the protection scope of the utility model.
Fig. 1-5 is please referred to, the utility model provides a kind of technical solution: a kind of natural gas line sealing and connecting device, packet
The first connecting tube 6 is included, the first connecting tube 6 is formed by two sections, and wherein the diameter of wider section is equal with the diameter of the second connecting tube 9,
And the diameter of thinner section is less than the inner diameter of the second connecting tube 9, so that the thinner section of the first connecting tube 6 can be in the second connecting tube
Sliding in 9, so as to stretch, the left end of 6 wider section of the first connecting tube is welded with ring flange 1, and the first connecting tube 6
The right end outer ring gluing of thinner section is fixed with the second sealing ring 8, and the outer ring of the second sealing ring 8 and the inner wall of the second connecting tube 9 are sliding
Dynamic connection, one end of remote first connecting tube 6 of the second connecting tube 9 is welded with ring flange 1, and the second connecting tube 9 nearly first connects
One end of adapter tube 6 is equipped with in-flanges, and the inner wall gluing of the in-flanges is fixed with the first sealing ring 7, the inner wall of the first sealing ring 7 with
The outer ring of first connecting tube, 6 thinner section is slidably connected, and the outer ring of the outer ring of 6 wider section of the first connecting tube and the second connecting tube 9 is equal
Strip groove 2 is offered, strip groove 2 is symmetrical about the two outer ring, the outer ring of the first connecting tube 6 and the second connecting tube 9
Equipped with connector sleeve 4, the inner wall of connector sleeve 4 is symmetrically distributed with strip bulge structure, and the strip bulge structure and first of connector sleeve 4
The strip groove 2 of connecting tube 6 and the second connecting tube 9 matches, this structure connects connector sleeve 4 in the first connecting tube 6 and second
The sliding of 9 outer ring of adapter tube, can be limited by strip groove 2, will not rotate shaking, so that connector sleeve 4 can only be left
It moves right, makes the connection of the two more stable and firm, the both ends of connector sleeve 4 are respectively equipped with adapter sleeve 3, and the inner wall of adapter sleeve 3 is cut
Face is at stairstepping, and the inner wall of the adapter sleeve 3 in nearly first connecting tube, the 6 direction outer ring with connector sleeve 4 and the first connecting tube 6 respectively
It is threadedly coupled, and the inner wall of the adapter sleeve 3 in nearly second connecting tube, the 9 direction outer ring spiral shell with connector sleeve 4 and the second connecting tube 9 respectively
Line connection, this structure can be attached it from the both ends of connector sleeve 4, so that the device is more stable and firm, sealing
More preferably, the equal gluing of the inner wall of adapter sleeve 3 is fixed with rubber ring 5 to property, and the diameter of the diameter and connector sleeve 4 of rubber ring 5 matches, this
Structure makes the connection between adapter sleeve 3 and connector sleeve 4 even closer, so that the leakproofness of the device is more preferably, first is close
The inner sidewall interference of seal 7 and the second sealing ring 8 respectively with the lateral wall of 6 thinner section of the first connecting tube and the second connecting tube 9 is matched
It closes, and the outer ring of the inner wall of the first sealing ring 7 and the second sealing ring 8 is concaveconvex structure, the first sealing ring 7 and the second sealing ring
8 use rubber material, this concaveconvex structure makes seamless company that can be even closer between the first connecting tube 6 and the second connecting tube 9
It connects, and due to the resilient characteristic of rubber material, so that still opposite can slide between the two, so as in telescopic adjustment
While, keep the leakproofness of the device.
Working principle: when using the natural gas line sealing and connecting device, first check that the device is broken with the presence or absence of part
The case where damaging or being not connected firmly, check it is errorless after carry out again using, then by the ring flange 1 at the device both ends by bolt difference
Original pipeline is connected, when causing tightly dock with existing pipeline when the device length is insufficient, by the tight of 4 both ends of connector sleeve
Admittedly the rotation counterclockwise respectively of set 3, makes adapter sleeve 3 mobile to two sides, is detached from adapter sleeve 3 and connector sleeve 4, and make to stay between the two
A distance out, connector sleeve 4 loses fastening force at this time, so that losing between the first connecting tube 6 and the second connecting tube 9
Then the fastening effect of connector sleeve 4 catches the first connecting tube 6 and the second connecting tube 9 respectively, the first connecting tube 6 and second is connected
Adapter tube 9 is dropped to opposite direction respectively, so that the second sealing ring 8 of 6 thinner section outer ring of the first connecting tube is along 9 light of the second connecting tube
Sliding inner wall slides, and makes the first sealing ring 7 of 9 inner wall of the second connecting tube along the outside of 6 thinner section of the first connecting tube
Wall slides, as needed that the device is convenient so as to stretch out the first connecting tube 6 and side length out of second connecting tube 9
Be adjusted to appropriate length, thus the tight connection between pipeline of being more convenient for, and due to the first sealing ring 7 and the second sealing ring
8 are interference fitted with the lateral wall of 6 thinner section of the first connecting tube and the inner sidewall of the second connecting tube 9 respectively, so that the first connecting tube 6
And second can remain close connection between connecting tube 9, ensure that the leakproofness of the device, finally again by 3 up time of adapter sleeve
Needle rotation, connect adapter sleeve 3 with the both ends of connector sleeve 4 respectively, the device can be made to be kept fixed；When needing to shorten the device
When, referring to the above method by 6 the second connecting tube of retraction 9 of the first connecting tube, easily the device can be adjusted and shortened, this is just
It is the working principle of the natural gas line sealing and connecting device.
