Problems solved by technology
At the same time, the current penetrating parts do not solve the problem of pipe wall structure vibration and fluid medium pulsation transmission to the bulkhead. There is no one that can not only meet the requirements of pipeline vibration isolation, but also meet the strength, sealing and reliability of the bulkhead. Elastic penetrating parts for multi-channel pipelines with high performance and other requirements

Embodiment Construction
[0022] The present invention will be described in detail below with reference to the accompanying drawings and examples.
[0023] as attached figure 1 and 2 As shown, it includes a small diameter tube 1, an inner tube 2, a limit pressure plate 3, a hexagon socket screw 4, a sleeve 5, an elastic body 6, a welding seat 8, a sealing gasket 10 and an inner tube limit ring 11;
[0024] The number of the small-diameter pipes 1 is four, and there are threaded joints at both ends;
[0025] The inner tube 2 is a closed cylindrical cavity structure;
[0026] The inner cavity of the sleeve 5 is an annular cavity, and the apertures at both ends of the sleeve 5 are larger than the outer diameter of the inner tube 2, and the inner circumference of the sleeve 5 extends radially with an annular protrusion structure, which can further strengthen the elastic body. 6 and the vulcanization strength of the inner tube 2;
[0027] The inner diameter of the limiting pressure plate 3 is larger tha...

The invention discloses a multi-channel elastic penetration of a pipeline and belongs to the technical field of vibration noise controlling of the pipeline. The penetration comprises small-diameter pipes, an inner pipe, limiting compressing plates, an elastic piece, a sleeve, a welding base plate, a sealing gasket and limiting rings of the inner pipe. The small-diameter pipes are fixedly connected with the inner pipe. The limiting rings of the inner pipe are axially fixedly connected to the inner pipe. The inner pipe, the limiting rings of the inner pipe and the sleeve are coaxially vulcanized together through the elastic piece. The limiting compressing plates are fixedly connected with two end surfaces of the sleeve. The welding base plate is welded to the outer circumferential surface of the sleeve. A threaded flange is connected with a system pipeline. A protrusion of the welding base plate is fitted and connected with a groove of a bulkhead. A portion between the protrusion and the groove is sealed by the sealing gasket. The elastic penetration has self-limiting, self-sealing and displacement compensating capabilities, resolves the problem of concentrated vibration isolation of penetration of the small-diameter pipeline and meets the requirements of strength, sealing performance and reliability of the bulkhead.
Description
technical field [0001] The invention relates to marine pipeline accessories, in particular to a pipeline multi-channel elastic penetrating part with self-limiting, self-sealing and displacement compensation capabilities applied in the field of shipbuilding, belonging to the technical field of pipeline vibration and noise control. Background technique [0002] The penetrating piece is one of the important accessories of the ship's piping system. It is a piping accessory used to penetrate watertight compartments, decks, tanks, etc. and keep the pipelines sealed. In order to maintain the strength, tightness and maintainability of the pipeline, there are usually two forms of ship penetrations: flange connection type penetrations and threaded joint penetrations. When the nominal diameter of the pipeline is DN≤32mm, the threaded joint penetration is usually used; when the nominal diameter of the pipeline is DN≥40mm, the flange connection type penetration with a screw-in flange is ...
