Detailed Description
The present invention will be further described with reference to the accompanying drawings.
Example one
The conversion piece for changing the pipe connection mode described with reference to fig. 1 and 2 comprises a clamping and pressing part 1 and a flange part 2. The clamping and pressing part 1 is a reducer pipe, a large-diameter end of the clamping and pressing part 1 is provided with a socket, one end of the flange part 2 is fixedly connected with a small-diameter end of the clamping and pressing part 1, and the other end of the flange part is provided with a connecting flange 4. The clamping and pressing portion 1 is connected with the first pipe fitting 7 in a clamping and pressing mode, the flange portion 2 is connected with the second pipe fitting 8 in a quick-release mode through a clamping hoop, and the sealing ring 6 is sleeved on the outer wall of the first pipe fitting 7. Through the conversion part can turn into flange joint with original card pressure connection, the structure is nimble, the reliability is high.
Specifically, a groove is arranged at the socket, and the cross section of the groove is of a right-angled trapezoid structure. The sealing ring 6 is connected in the groove, the tail end of the bellmouth extends along the radial direction to form a skirt edge 10, and the skirt edge 10 is one side wall of the groove. The sealing ring 6 is an O-shaped ring or an elliptic ring. In this embodiment, the clamping and pressing portion 1 is a one-way clamping and pressing portion.
In addition, a flat gasket is arranged on the butt joint surface of the connecting flange 4 and the second pipe fitting 8 so as to ensure the tightness of the second pipe fitting and the sealing ring.
Example two
Referring to fig. 3, the difference between the conversion member for changing the connection manner of the pipe fittings and the first embodiment is that an anti-pulling ring 9 is further disposed in the groove, the anti-pulling ring 9 is disposed coaxially with the sealing ring 6, the anti-pulling ring 9 is sleeved on an outer wall of the insertion end of the first pipe fitting, and the anti-pulling ring 9 is disposed near the skirt 10. The effect of the one-way clamping in the present embodiment is different from that of the first embodiment in that the anti-pulling capability is greatly mentioned, because the anti-pulling ring can be deformed together when the clamping portion is clamped.
EXAMPLE III
The difference between the conversion member for changing the connection mode of the pipe fittings described with reference to fig. 4 to 5 and the second embodiment is the shape of the groove. The side walls of the clamping and pressing parts 1 on the two sides of the groove extend along the axis and are sleeved on the outer wall of the first pipe fitting 7, so that the groove is of an isosceles trapezoid structure, and meanwhile, two sealing rings can be installed in the groove and are respectively arranged on the two sides of the anti-pulling ring 9. Compared with other embodiments, the anti-pulling ring is added, meanwhile, bidirectional clamping pressure can be achieved for the clamping pressure part, and the anti-pulling capacity is further improved.
The above description is only a preferred embodiment of the present invention, and it should be noted that: for those skilled in the art, without departing from the principle of the present invention, several improvements and modifications can be made, and these improvements and modifications should also be considered as the protection scope of the present invention.
