Double-sealing forcipressure type sound testing tube

Abstract

The invention discloses a double-sealing forcipressure type sound testing tube. The double-sealing forcipressure type sound testing tube comprises an outer casing assembly and a sealing assembly, wherein the sealing assembly comprises a blocking plate, a rubber gasket, a socket end and a thread strip; the blocking plate is arranged at the outside wall of the right side of a first tube body, and isfixedly connected with the first tube body; the rubber gasket is arranged at the right side of the blocking plate, and is glidingly connected with the blocking plate; the left side of a second tube body is provided with the socket end; the socket end is fixedly connected with the second tube body. The double-sealing forcipressure type sound testing tube is characterized in that firstly, the inside wall of the socket end is chiseled with the thread strip, and a convex thread is arranged at a spigot end, so that when the sound testing tube is installed, the sound testing tube can be directly inserted and then rotated to complete connection, the operation is simple and convenient, and the use of external tools is not required; then, the rubber gaskets are arranged at the socket end and the spigot end, and are extruded and tightly adhered together, so that the good sealing property is maintained, and the leakage of sound is reduced.

Description

Technical field [0001] The invention belongs to the technical field of acoustic measuring tubes, and specifically relates to a double-sealed clamp pressure type acoustic measuring tube. Background technique [0002] The clamp pressure acoustic tube is designed with two convex grooves at the end of the socket, and the convex groove is equipped with a sealing ring. When installing, insert the socket end of the product into the socket end, and then use special hydraulic clamps to simultaneously align the two convex grooves. The groove is squeezed, and the pipe at the squeezed part shrinks and deforms after being forced, and the outer pipe between the two convex grooves is deeply embedded in the inner pipe, which can realize reliable connection. [0003] In the installation of the traditional acoustic tube, two separate pipe ports are plugged together, and then the two clamp angles of the hydraulic clamp are used to forcefully squeeze the clamping part of the pipe. This is troublesome ...

AI Technical Summary

Problems solved by technology

[0003] The installation of the traditional acoustic tube is to plug two separate pipe ports together, and then use the two clamp angles of the hydraulic pliers to forcefully squeeze the pipe engaging part, which is cumbersome to operate and requires the help of external tools. It is not conducive to the installation and use of the acoustic tube. The original acoustic tube only contains a sealing ring, which reduces the sealing performance and affects the detection effect.
