Detailed ways

First of all, a specific description is given to Embodiment 1 of the present utility model. As shown in Figures 1 and 2, an anti-vibration four-way valve includes a valve body 1 and a connecting pipe 11, and the connecting pipe 11 is connected to the valve body 1. The connecting pipe 11 is connected with a restraint device. In this embodiment, the restraining device is a horizontal connecting piece 2 that connects at least two connecting pipes into one body. The horizontal connecting piece 2 is provided with a groove 21 corresponding to the connecting pipe, and the groove 21 is buckled on the outer circle of the connecting pipe 11 .

Wherein, only one piece of horizontal connecting piece 2 is provided, and this piece of horizontal connecting piece 2 is arranged on one side of the connecting pipe 11, perpendicular to the connecting pipe 11, and the groove 21 is fastened to the outer circle of the connecting pipe 11, and then It is welded and fixed with the connecting pipe 11. Alternatively, the horizontal connecting piece 2 is arranged in two pieces, and the two horizontal connecting pieces 2 are arranged side by side on both radial sides of the connecting pipe 11, perpendicular to the connecting pipe 11, and the groove 21 is fastened outside the connecting pipe 11. circle, finally welded and fixed with connecting pipe 11.

Embodiment 2, as shown in FIGS. 3 to 5 , is different from Embodiment 1 in that in this embodiment, a pair of horizontal connecting pieces 3 is provided, and the first horizontal connecting piece 31 is arranged in the radial direction of the connecting pipe 11. On one side, the second horizontal connecting piece 32 is arranged on the other radial side of the connecting pipe 11. The horizontal connecting piece 3 and the connecting pipe 11 are vertically intersected. The first horizontal connecting piece 31 and the second horizontal connecting piece The groove 33 on the inner side of the connecting piece 32 is buckled on the outer circle of the connecting pipe 11 , and then fixed with the connecting pipe 11 by screws 34 . Since the pair of horizontal connecting pieces 3 are fixed by screws 34, the assembly and disassembly is facilitated.

As shown in Figure 4, in the pair of horizontal connecting pieces 3, the first horizontal connecting piece 31 is provided with a through hole 311 at the two ends and between the grooves along the length direction, while the second horizontal connecting piece The sheet 32 is provided with threaded holes 321 at both ends and between the grooves 33 along the length direction. The screw 34 described in 5 is fixed after passing through the through hole 311 and the threaded hole 321.

Embodiment 3, as shown in Figure 6 and Figure 7, is different from Embodiment 1 and Embodiment 2 in that the connecting piece used in the restraint device is an integrated fixed connecting piece 4, and the integrally fixed connecting piece 4 connects the connecting pipe 11 is fixed at the same time, it is also fixedly connected with the valve body 1 integrally, so that each connecting pipe 11 is restrained integrally, and each connecting pipe 11 is also restrained on the valve body 1 at the same time, which further improves the anti-vibration performance.
