Detailed Description

The following description is only a preferred embodiment of the present invention, and does not limit the scope of the present invention.

In an embodiment, as shown in fig. 1 to 5, the branch joint assembly includes an elastic sealing member 30, a first clip member 10 and a second clip member 20, the first clip member 10 including a first clip groove 11 and a first mounting groove 12 having an arc shape, and the second clip member 20 including a second clip groove 21 and a second mounting groove 22 having an arc shape. The first clip member 10 is fitted to the second clip member 20, the first clip groove 11 and the second clip groove 21 are closed to form a first fitting hole, the first mounting groove 12 and the second mounting groove 22 are closed to form a second fitting hole, and an axis of the second fitting hole intersects with an axis of the first fitting hole. The elastic sealing member 30 surrounds the opening of the second fitting hole and protrudes toward the axial direction of the first fitting hole, and the elastic sealing member 30 is made of an elastic material. Alternatively, the elastic seal member 30 is made of an elastic material such as rubber.

The branch fitting assembly is used to connect the main conduit 50 and the branch conduit 60 such that the gaseous or liquid-like fluid medium in the main conduit 50 enters the branch conduit 60. The main pipe 50 has a pipe diameter much larger than that of the branch pipe 60, and the main pipe 50 is provided with a flow hole 51. Alternatively, the aperture diameter of the flow hole 51 is slightly larger than the pipe diameter of the branch pipe 60 so that the branch pipe 60 can be inserted into the flow hole 51. Optionally, the aperture of the circulation hole 51 is equal to or has a small difference with the aperture of the branch line 60, so as to increase the circulation efficiency of the fluid and reduce the size of the opening of the main line 50.

The axis of the second fitting hole intersects the axis of the first fitting hole, corresponding to the extending direction of the main pipe 50 and the extending direction of the branch pipe 60. For example, the axis of the second fitting hole is perpendicular to the axis of the first fitting hole; alternatively, the axis of the second fitting hole intersects obliquely with respect to the axis of the first fitting hole to adjust the installation direction of the branch piping 60 with respect to the main piping 50.

The elastic sealing member 30 is disposed on the branch line 60 such that the elastic sealing member 30 is located at a connection position between the branch line 60 and the main line 50. The first clamp piece 10 and the second clamp piece 20 are mutually folded to clamp the main pipeline 50 and the branch pipeline 60, wherein the main pipeline 50 is tightly connected with the first assembling hole, the branch pipeline 60 is tightly connected with the second assembling hole, the elastic sealing element 30 is elastically deformed under the extrusion force action of the first clamp piece 10 and the second clamp piece 20, so that the end surface of the elastic sealing element 30 is tightly attached to and seals the wall surface of the main pipeline 50, and the hole wall of the elastic sealing element 30 is tightly attached to and seals the pipe wall of the branch pipeline 60.

As shown in fig. 2 and 3, the elastic seal 30 includes a bottom wall 33, an inner annular rib 32 and an outer annular rib 31 protruding from the bottom wall 33, the outer annular rib 31 surrounds the inner annular rib 32, and the inner annular rib 32, the bottom wall 33 and the outer annular rib 31 form a groove-shaped pressure groove 322. The inner annular rib 32 surrounds to form a mounting hole 321, the mounting hole 321 is coaxial with the second assembling hole, and the aperture of the mounting hole 321 is smaller than that of the second assembling hole. The end face of the outer annular rib 31 forms a sealing surface 311, and the sealing surface 311 protrudes from the hole wall of the first fitting hole.

The elastic sealing member 30 is fitted over the branch line 60, and the wall surface of the inner annular rib 32 corresponding to the mounting hole 321 is tightly fitted to the wall of the branch line 60. A bottom wall 33 and an outer annular rib 31 are defined on the first and

second clip members

10 and 20 to support the outer annular rib 31 projecting toward the center line direction of the first fitting hole. The free end of outer annular rib 31 is sealed with the periphery wall of main pipeline 50 and is laminated, and extrusion sealing effect is good. Between outer annular bead 31 and the inner annular bead 32 that pressure groove 322 is located, when media such as gas or liquid entered into pressure groove 322, outer annular bead 31 and inner annular bead 32 elastic deformation under the pressure effect of media further improved the combination compactness between inner annular bead 32 and branch pipeline 60 to and improve the combination compactness between outer annular bead 31 and main pipeline 50.

In one embodiment, the sealing surface 311 extends from the pressure groove 322 in a curved manner in two directions away from each other to form a smooth curved surface. The sealing surface 311 is an arc-shaped curved surface or an involute-shaped curved surface, and the elastic sealing element 30 can be closely attached to the outer peripheral wall of the main pipeline 50, so that the attachment effect is good. Optionally, the sealing surface 311 has a radius of curvature that is less than the radius of the main conduit 50 such that the resilient seal 30 expands along the surface of the main conduit 50 and the sealing surface 311 presses sealingly against the surface of the main conduit 50. Optionally, the radius of curvature of the sealing surface 311 is greater than or equal to the radius of the first mounting hole, so that the sealing surface 311 gradually fits the surface of the main pipeline 50 from the direction of the pressure groove 322, the sealing and bonding tightness near the mounting hole 321 is improved, and the sealing effect of the interface portion is good. Alternatively, the mounting hole 321 is located at the center of the curved surface of the seal surface 311 so that the seal surface 311 is symmetrical with respect to the branch line 60, and the seal range is well balanced.

In an embodiment, the inner annular rib 32 is inclined from the bottom wall 33 to a center line direction of the mounting hole 321, so that when the branch pipeline 60 is inserted into the main pipeline 50 along the mounting hole 321, the inner annular rib 32 is gradually tensioned and attached to a pipe wall of the branch pipeline 60. I.e. the inner annular bead 32 is of a structure approximating a conical tube wall. Accordingly, the wall of the mounting hole 321 is tapered, and the branch pipe 60 is inserted along the large hole end of the mounting hole 321, so that the inner annular rib 32 is tightly connected to the branch pipe 60, and the sealing performance is high. Optionally, the thickness of the inner annular bead 32 is balanced to improve the structural strength of the inner annular bead 32. Optionally, the thickness of the inner annular bead gradually decreases from the bottom wall 33 to the free end to increase the bonding area of the tension connection between the inner annular bead 32 and the branch pipeline 60.

Further, the projection length of the inner annular rib 32 in the axial direction of the mounting hole 321 is smaller than the projection length of the outer annular rib 31 in the axial direction of the mounting hole 321. The projection lengths of the inner annular rib 32 and the outer annular rib 31 in the center line direction of the mounting hole 321 are different, so that the free end of the inner annular rib 32 and the free end of the outer annular rib 31 have a height difference, and the height difference can avoid the free end of the inner annular rib 32 from being abutted to the main pipeline 50. The opening of the pressure groove 322 is directed to the joint between the main pipe 50 and the branch pipe 60, so that the inner annular bead 32 and the outer annular bead 31 constituting the groove wall of the pressure groove 322 are brought into contact with the main pipe 50 and the branch pipe 60, respectively, by the pressure of the medium, thereby improving the sealing property.
