Detailed Description

The embodiments of the present invention will be described in detail below, examples of which are illustrated in the accompanying drawings, and the embodiments described below by referring to the drawings are exemplary and intended to explain the present invention so that the technical solutions of the present invention can be more easily understood and grasped, and cannot be construed as limiting the present invention.

Example (b):

a sleeve 2 assembly for a flow control valve is shown in figure 1 and will be described with the upper end in the schematic drawing and the lower end in the rear. The sleeve 2 assembly comprises an inner cylinder connecting pipe 1, a sleeve 2 and an inner cylinder joint 3, and C40 steel is adopted. One end of the inner cylinder connecting pipe 1 and the sleeve 2 are mutually sleeved and riveted and fixed, and cannot be detached after being fixed, so that the connection and the separation are avoided, and the sealing performance is improved. The sealing ring 4 is arranged on the sleeve joint surface of the inner cylinder connecting pipe 1 and the sleeve pipe 2, the riveting position 5 is located at the rear end of the sealing ring 4, the front end of the sleeve pipe 2 is sleeved and fixed with the inner cylinder connector 3 in a threaded connection mode, the plane valve block 6 is arranged between the inner cylinder connector 3 and the two end surfaces of the inner cylinder connecting pipe 1, and the arc valve block 7 is arranged at the rear end of the plane valve block 6.

Referring to fig. 1 and 2, the upper and lower surfaces are parallel planes for the structure of the planar valve sheet 6, i.e., the annular structure. The arc-shaped valve plate 7 is of a three-dimensional annular structure, is obtained by stamping and shaping the annular plate, has a three-dimensional structure, is in a wave shape, and has a plurality of wave crests and wave troughs. The circumferential surface of the arc valve plate 7 is provided with 3-5 wave crests. And selecting the arc valve plates 7 with proper wave crest numbers according to actual requirements. The larger the number of peaks, the less the elastic capacity of the structure is, so that the more the range is selected.

In addition, 10-14 riveting positions 5 of the sleeve 2 are uniformly distributed in the circumferential direction. Therefore, the sealing performance can be improved, the connection can be reliable, the sleeve 2 is not easy to break away, other people are not required to detach, and the damage is avoided.

The inner wall of the rear end of the inner cylinder connecting pipe 1 is provided with a circular sealing ring 8 and a plane sealing ring 9. This improves the sealing performance of the rear end of the inner tube adapter 1.

More importantly, referring to fig. 1, the diameter 2 × L2 of the rear end of the sleeve 2 is larger than the diameter 2 × L1 of the front end of the sleeve 2, the inner wall of the sleeve 2 is stepped, and the diameter 2 × L2 of the arc valve plate 7 is larger than the diameter 2 × L1 of the plane valve plate 6.

In the assembly process, the planar valve plate 6 is required to be placed firstly, then the arc valve plate 7 is placed, the sealing ring on the inner cylinder connecting pipe 1 is sleeved, the inner cylinder connecting pipe 1 is inserted into the rear end of the sleeve pipe 2, and riveting fixing is carried out at the riveting position 5. And finally, assembling an inner cylinder joint 3 at the other end, namely the upper end, of the sleeve 2, wherein the inner cylinder joint 3 can be adjusted in a threaded connection mode and abuts against the plane valve plate 6 and the arc valve plate 7.

Of course, the above is only a typical example of the present invention, and besides, the present invention can also have other various specific embodiments, and all technical solutions adopting equivalent replacement or equivalent transformation are all within the scope of the present invention as claimed.
