Embodiment Construction

[0042] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0043] like figure 1 As shown, a pipeline hydrophone stuffing box includes a stuffing box seat 1, a diversion sheath 2, more than two stuffing backing plates 3, stuffing 4, and a stuffing gland 5;

[0044] like Figure 2-Figure 3 As shown, the stuffing box seat 1 is a hollow cylindrical structure with openings at both ends, one end is welded to the opening of the pipeline by the H63 method, and the other end has a shoulder extending to the outside of the stuffing box seat 1;

[0045] The central hole of the stuffing box seat 1 is a stepped hole, and the diameter of the connecting end with the pipeline is relatively small;

[0046] like Figure 4-Figure 5 As shown, the diversion sheath 2 is a circumferentially split cylindrical structure, that is, a cylindrical structure formed by splicing two or more petals along the circumferential direction, and one e...

Abstract

The present invention provides a pipeline hydrophone stuffing box and a usage method thereof. A diversion sheath that can be spliced wraps a hydrophone, so that a gap between the head of the hydrophone and a pipeline wall can be filled. A filling backing plate and a filling pressure cover are both circumferential split structures, after a cable is laid, the spliced diversion sheath, the filling backing plate and the filling pressure cover wrap the hydrophone, and finally the hydrophone is installed in a stuffing box base, so that the hydrophone can be installed without conventionally penetrating a tail cable of the hydrophone out of the stuffing box in advance from the interior of a pipeline, and finally laying the more disordered cable penetrating out of the stuffing box. The pipeline hydrophone stuffing box and the usage method thereof are suitable for the conditions that the head of the hydrophone is larger, and the installation is inconvenient.

Description

technical field [0001] The invention belongs to the field of underwater acoustic measurement, and in particular relates to a stuffing box of a pipeline hydrophone and a method for using the same. Background technique [0002] When measuring the water sound in the pipeline of the mechanical system, it is necessary to install the hydrophone in the appropriate position of the pipeline. The installation device of the hydrophone needs to meet two conditions, one is to have good water tightness, and the other is to be installed in an effective way sound of water. Since the detection position of the general hydrophone is far away from the data acquisition analyzer, it often spans multiple cabins, so the waterproof cable at the tail of the hydrophone is longer. Since the head of the hydrophone is larger than the central opening of the ordinary stuffing box, Therefore, when using an ordinary stuffing box, the waterproof cable at the tail of the hydrophone is usually inserted into th...
