The specific meaning of the above terms in the creation of the present invention can be understood by those of ordinary skill in the art through specific situations.

The invention will be described in detail with reference to the following embodiments with reference to the attached drawings.

A distributor and branch liquid separating pipe connecting structure is shown in figures 1 to 3 and comprises a distributor body 1, wherein one end of the distributor body is provided with an opening 2, and the other end of the distributor body is provided with a partition plate 3; a plurality of mounting holes 4 are punched inwards on the partition board, and flanges 5 are formed on the inner sides of the mounting holes; a positioning sleeve 6 is fixed on the outer side of the partition plate corresponding to each mounting hole; and a sealing element 7 is arranged between the positioning sleeve and the branch liquid separating pipe. For example, the inner wall of the positioning sleeve is provided with a sealing groove, and the sealing element is installed in the sealing groove. Preferably, the seal comprises a lip seal.

Of course, it is also possible to use O-rings for the sealing elements. Adopt lip seal can effectively prevent medium outflow in the distributor, have better sealed effect, when using lip seal, even medium has certain pressure in the distributor, also can obtain reliable seal.

A branch liquid separating pipe 8 is inserted into each mounting hole of the partition plate, the length of the positioning sleeve is larger than the radius of the branch liquid separating pipe, the part of the branch liquid separating pipe inserted into the inner side of the distributor body is supported by a flanging, and the part of the branch liquid separating pipe positioned on the outer side of the partition plate is supported by the positioning sleeve. Usually, the turn-ups is connected with branch liquid pipe terminal card pressure, forms the distributor body and divides the first seal between the branch liquid pipe, and the sealing member between position sleeve and branch liquid pipe is as the distributor body and divide the second seal between the branch liquid pipe, furthest guarantees the leakproofness of distributor and branch liquid pipe connection structure part.

Usually, the length of the positioning sleeve in the axial direction is 1-2.5 times of the radius of the branch liquid-separating pipe, so that the branch liquid-separating pipe can be effectively supported, the stable structure of the part of the branch liquid-separating pipe, which is extended out of the distributor body, is ensured, and the strength of the whole structure is also ensured.

In an alternative embodiment, as shown in fig. 4, each of said branch liquid distribution pipes is provided with a control valve 9. Generally, the control valve employs a solenoid valve. The flow of the medium in the liquid separating branch pipe can be controlled by adjusting the opening of the control valve according to needs, the control is convenient, the operation is simple, and the automation is easy to realize.

In order to ensure the reliability of the clamping and fixing connection of the flanging and the branch liquid-distributing pipe, in an alternative embodiment, the end of the branch liquid-distributing pipe inserted into the distributor body is provided with a plurality of grooves 10. Typically, the grooves are arcuate in cross-section. When the turn-ups was pressed fixedly with dividing liquid branch pipe card, turn-ups part embedding recess was interior, and the axial restriction divides liquid branch pipe displacement, and the radial drunkenness of branch pipe can be prevented again in the radial from the footpath, effectively prevents to divide liquid branch pipe to break away from, and simultaneously, the position sleeve (and mounting hole) can effectively prevent to divide liquid branch pipe radial drunkenness, has greatly improved the stability that divides liquid branch pipe.

During assembly, the liquid distribution branch pipe is inserted into the mounting hole from the outer end of the positioning sleeve until the tail end of the liquid distribution branch pipe is matched with the flanging part, and then the flanging is connected with the tail end of the liquid distribution branch pipe in a pressing mode and fixed. Because the locating sleeve is arranged coaxially with the corresponding mounting hole, when the liquid separation branch pipe is inserted into the mounting hole through the locating sleeve, the accuracy of the mounting position of the liquid separation branch pipe can be effectively ensured, and meanwhile, after the liquid separation branch pipe is inserted in place, a stable matching relation is formed between the liquid separation branch pipe and the mounting hole (and structures on two sides of the mounting hole).

In addition, during actual production and assembly, a tool can be inserted from the open side of the distributor body to clamp the flanging on the liquid distribution branch pipe. It should be noted that, even for a small-sized distributor body, when the open space is limited and the branch liquid pipe is not convenient to clamp, the small-sized distributor body can be pre-processed and manufactured into a two-piece structure (the two pieces are cut in the length direction), a tool is extended from the cut end, clamping and pressing assembly between the distributor main body and the branch liquid pipe is more convenient, after the branch liquid pipe is assembled, the two pieces of the distributor main body are welded into a whole, and a weld bead is positioned on the outer side of the distributor main body, so that the use performance is not influenced.

The invention has simple structure and reasonable design, the branch liquid pipes do not need to be welded, the possibility that welding slag falls into the distributor body is reduced, the use reliability of the distributor is improved, and the flow stability of a medium in the distributor is ensured. Because the part of the branch liquid-separating pipe inserted into the inner side of the distributor body is supported by the turned-over edge, the displacement of the branch liquid-separating pipe is limited from the axial direction, the radial movement of the branch liquid-separating pipe can be prevented from the radial direction, and the branch liquid-separating pipe can be prevented from falling off.

Meanwhile, the part of the liquid separating branch pipe, which is positioned outside the partition plate, is supported by the positioning sleeve, and the positioning sleeve and the mounting hole can effectively prevent the liquid separating branch pipe from radially moving, so that the liquid separating branch pipe is very convenient to mount and fix, and the connection reliability and stability are very high.

In addition, the sealing element between the locating sleeve and the liquid separating branch pipe has good sealing performance of the connecting part of the distributor and the liquid separating branch pipe, and the sealing element can also effectively support the liquid separating branch pipe, prevent the liquid separating branch pipe from shaking in the using process and play a role in damping and noise reduction.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and should not be taken as limiting the invention, so that any modifications, equivalents, improvements and the like, which are within the spirit and principle of the present invention, should be included in the scope of the present invention.
