Problems solved by technology

[0002] Most of the existing gas and liquid pipe connection joints, such as tee joints, are hard-connected and sealed, but the hard-sealed connection type is difficult to take into account both sealing and practical aspects. In order to achieve high sealing performance, the hard-sealed connection requires material and processing requirements. Harsh and expensive
For some gas and liquid transportation pipelines, when the temperature and pressure of the medium are not very high, if the seal pipe joints of hard materials such as metal are used, it is not only overkill, but also a great waste of resources
In addition, the hard seal type is very strict on the purity of the medium. If the medium contains particles, it will be a fatal injury to the hard seal type.

Embodiment Construction

[0013] Referring to the accompanying drawings, the present invention includes a wire base 1, a tube base 3 and a nut 4, the wire base 1 and the tube base 3 are fixed together by the nut 4, and a groove is arranged on the head of the wire base 1, A sealing ring 2 is arranged in the groove. The sealing ring 2 is made of elastic material. The working principle is:

[0014] As shown in the accompanying drawings, the wire seat in the figure can be the wire seat in the three-head pipe joint, or straight through, as long as the structure of the wire seat is guaranteed, the nut 4 cooperates with the wire seat 1, and the pipe seat 3 passes through The nut 4 is fixed with the wire base 1, and the sealing ring 2 is placed in the groove of the head of the wire base 1 in the figure, and the sealing ring can be placed in the outer diameter groove of the wire base 1 in some applications. The sealing principle is to use the pre-tightening force of the nut 4 in the working process to make th...

Abstract

The invention relates to a novel sealing mechanism. The novel sealing mechanism comprises a screw seat, a pipe seat and a nut, wherein the screw seat and the pipe seat are fixed together through the nut; a groove is formed in the head of the screw seat; and a sealing ring is arranged in the groove. According to the novel sealing mechanism disclosed by the invention, nonmetallic materials having certain strength, certain hardness and certain temperature resistance are used for soft sealing connection, so that the sealing property is good, and zero leakage can be achieved.

Description

technical field [0001] The invention belongs to the field of manufacturing technology, and in particular relates to a novel sealing mechanism. Background technique [0002] Most of the existing gas and liquid pipe connection joints, such as tee joints, are hard-connected and sealed, but the hard-sealed connection type is difficult to take into account both sealing and practical aspects. In order to achieve high sealing performance, the hard-sealed connection requires material and processing requirements. Harsh and expensive. For some gas and liquid transportation pipelines, when the temperature and pressure of the medium are not very high, if the seal pipe joints made of hard materials such as metal are used, it is not only overkill, but also a great waste of resources. In addition, the hard seal type is very strict on the purity of the medium. If the medium contains particles, it will be a fatal injury to the hard seal type.
