時に防止する。In the present invention, since the vibration-proof rubber sandwiched between the vibration-proof rubber supporting portions formed at the connecting ends of both pipes has a significantly lower elastic modulus than that of the piping material, Vibration is not transmitted to the other pipe. Due to the flexibility of the rubber packing, the rubber packing blocks transmission of vibrations that try to be transmitted through the bolts and nuts that fasten the anti-vibration rubber support portions at both pipe ends. Moreover, the collision damper rubber prevents the vibrations from being transmitted due to the collision of the opposing end faces of the anti-vibration rubber support portion.
The hole of the orifice held in the inner diameter portion of the anti-vibration rubber resists the pulsation of the fluid flowing in the pipe and smoothes the pulsation. Since the orifice is held by the inner diameter of the vibration isolating rubber, the vibration isolating rubber absorbs the vibration generated in the orifice by the pulsation of the fluid. In this way, the anti-vibration pipe joint simultaneously prevents vibration of the pipe and propagation of pulsations of the fluid flowing in the pipe.

防止する。If a fluid, such as a pump (not shown), is circulated in the pipe 1 connected and connected as shown in FIG.
Vibration may occur, or pulsation may occur in the fluid flowing in the pipe 1. The vibration generated in one side of the pipe 1 is transmitted from the vibration-proof rubber supporting portion 5 of the joint pipe 10 to the vibration-proof rubber 2 to vibrate the vibration-proof rubber 2. However, pipe 1, joint pipe 1
0, the elastic coefficient of the anti-vibration rubber 2 is much lower than that of the anti-vibration rubber support portion 5, so that the vibration transmitted from one pipe 1 to the anti-vibration rubber 2 is unique to the anti-vibration rubber. Since it is orders of magnitude higher than the frequency of vibration, it cannot travel in the anti-vibration rubber 2. The vibration propagating in the anti-vibration rubber 2 cannot be transmitted because the anti-vibration rubber support portion 5 on the other side, which has a high elastic coefficient and an order of magnitude of natural frequency, cannot vibrate. In addition, a fastening bolt 4 and a fastening nut 8 for fastening both anti-vibration rubber support portions 5
Since the flexible rubber packing 9 having a low elastic coefficient is interposed, the vibration to be transmitted via the rubber packing 9 blocks the transmission of the vibration for the same reason. Also,
The collision damper rubber 6 prevents noise and vibration from being transmitted when the opposing end surfaces of the vibration-proof rubber supporting portion 5 collide.

時に防止する。Further, in FIG. 1, the orifice 3 held in the inner diameter portion of the vibration isolating rubber 2 resists the pulsation of the fluid passing through the orifice hole 3h to smooth the pulsation. Further, since the outer peripheral portion of the orifice 3 is embedded and held in the inner diameter portion of the vibration isolating rubber 2, the vibration isolating rubber 2 absorbs the vibration generated in the orifice 3 by the pulsation of the fluid. In this way, the vibration-proof pipe joint simultaneously prevents the vibration of the pipe and the pulsation of the fluid flowing in the pipe to the downstream side.

Is not formed, but as a separate part, a half-split cover divided into the upper and lower parts of the figure is formed in a shape that covers both anti-vibration rubber support parts 5, 5, and both anti-vibration rubber support parts 5, 5 are formed. The structure may be such that it is attached to 5 via a sponge or rubber packing. With such a structure, when assembling this vibration isolation pipe joint, and when replacing the vibration isolation rubber 2 holding the orifice 3, the vibration isolation rubber 2 can be taken out by removing the fastening bolt 4. A new anti-vibration rubber 2 can be inserted, and the fastening of both pipes 1 and the joint pipe 10 can be easily performed without disassembling. Further, it is also possible to directly form the vibration damping rubber support portion 5 on the connection end portion of the pipe 1 and omit the joint pipe 10.
