Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely below, and it should be apparent that the described embodiments are only some embodiments of the present invention, but not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
Referring to fig. 1 and 2, a miniaturized gas tight joint is provided, which includes a gasket 1, a connecting pipe 2, an internally threaded nut 3, a ferrule 4 and a nut 5. The gasket 1 is arranged in a manner of colliding with the end part of the connecting pipe 2 and is positioned in the internal thread nut 3. The structure of the top end of the connecting pipe of the gas sealing joint is kept unchanged, and the gasket 1 and the connecting pipe 2 are arranged in sealing contact. The gasket 1 is a metal gasket. Because the internal thread is arranged in the internal thread nut 3, the gasket 1 and the connecting pipe 2 are fixed by connecting the internal thread nut 3 with the connecting pipe or the valve body of the gas sealing joint at the other side through screwing, and at the moment, a traditional gas sealing joint assembly mode is formed.
One end of the connecting pipe 2 is positioned in the internal thread nut 3, and the other end of the connecting pipe extends out of the internal thread nut 3. The adapter 2 comprises a connecting body 24, a flat body 21 and a connector body 22, wherein the connecting body 24 is connected with the connector body 22, and a bulge 23 and the flat body 21 are arranged on the connecting body 24. The flat body 21 is formed by adding two cuts in the direction parallel to the outer wall of the connecting body 24, and the two cuts form the flat body 21. The flat body 21 can facilitate the fixing of a wrench. The length of the flat body 21 is 3mm at the minimum, and in the present embodiment, the length of the flat body 21 is 3mm, which is the lowest length setting. The projection 23 enables the nipple 2 to be snapped onto the internally threaded nut 3. The joint body 22 at the tail end of the adapter tube 2 is the joint body 22 of a ferrule type tube joint. The connecting body 24, the connector body 22 and the protrusion 23 are integrally formed. The protrusion on the connecting body 24 is a ring-shaped protrusion on the connecting body 24.
The female threaded nut 3 is provided with a test port 31. The number of the test ports 31 may be one or more, in this embodiment, the number of the test ports 31 is two, and two test ports 31 are provided on the side surface of the internally threaded nut 3. The test port 31 facilitates leak testing.
The clamping sleeve 4 is inserted into the connecting pipe 2, the nut 5 is sleeved on the connecting pipe 2, the tail end of the connecting pipe becomes a joint body 22 of the clamping sleeve type pipe joint, and the clamping sleeve 4 and the nut 5 of the clamping sleeve type pipe joint are matched for connection. The ferrule 4 comprises a front ferrule 41 and a rear ferrule 42, the rear ferrule 42 is inserted into the front ferrule 41, the front ferrule 41 is in a cone frustum shape, and the rear ferrule 42 is provided with an annular bulge on the cone frustum. The inner wall of the connector body 22 is conical, and the inner wall of the connector body 22 is matched with the clamping sleeve 4. The flat body 21 formed at the middle end of the adapter tube 2 is fixed by a wrench, the ferrule 4 and the nut 5 of the ferrule tube joint are sleeved on a steel tube and inserted into the joint body 22, the nut 5 is screwed to enable the outer side of the front end of the front ferrule 41 to be tightly attached to the conical surface in the joint body 22, the inner side of the front ferrule 41 is tightly attached to the outer diameter of the ferrule tube to be connected, the inner side of the ferrule 4 is uniformly engaged into the seamless steel tube, and the joint is effectively sealed. The connecting mode enables the gas sealing joint and the ferrule type pipe joint to be connected into a whole, and welding or ferrule type pipe connection is not needed after the connecting pipe of the traditional gas sealing joint is led out for a long distance, so that the connecting length is shortened.
