Embodiment Construction
[0012] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.
[0013] The first example is figure 1 As shown, there is a barrel-shaped sound-conducting water tank 2. The bottom of the sound-conducting water tank is provided with connecting slots with the same width as the diameter of the pipe to be tested. Semicircular holes are set at both ends of the connecting slot to match the pipe to be tested. The connecting slots The connection and containment surface of the transverse section of the outer pipe wall of the round pipe is equal to half the cross section of the round pipe. The connecting slot of the sound conduction water tank is welded together with the outer pipe wall of the tested pipe 1 to form a fixed and sealed connection structure. The sound conduction water tank consists of It is made of metal material, and the bottom of the inner wall of the water tank and its surroundings are lined with a sound-absorbi...
