Description

Technical Field

[0001] The present invention relates to the technical field of ship auxiliary construction, and in particular to a flexible watertight passage component for a high-pressure pipeline and an installation method thereof. Background Art

[0002] With the significant increase in ship deadweight tonnage in recent years, in order to meet the requirements of use, ship hydraulic equipment has higher requirements on power.

[0003] A ship's hydraulic system consists of a hydraulic pump station and hydraulic equipment. The hydraulic pump station includes a hydraulic pump, hydraulic cylinder, and hydraulic valve. The hydraulic pump delivers high-pressure fluid to the hydraulic cylinder, while the hydraulic valve controls the flow of the fluid. Hydraulic equipment experiences frequent changes in hydraulic fluid pressure and direction depending on operating conditions. Hydraulic piping, as the carrier of high-pressure fluid and the transmission of pressure and power between hydraulic components, requires sufficient strength, sealing, and appropriate flexibility to prevent leakage and pressure loss caused by piping deformation.

[0004] To protect the equipment, the hydraulic unit is located in a room below the main deck, while hydraulic equipment such as the windlass and winch are placed in specific operating locations on the main deck. The hydraulic lines connecting the hydraulic unit and hydraulic equipment inevitably pass through the main deck watertight bulkhead. Conventional fixed watertight pipe passages cannot deform synchronously with the hydraulic lines, resulting in leakage at the flange connections of the hydraulic pipe passages, causing hydraulic oil to spray and posing a fire hazard.

[0005] Therefore, it is necessary to provide a high-pressure pipeline flexible watertight through-chamber component and an installation method thereof to solve the above technical problems. Summary of the Invention

[0006] The purpose of the present invention is to address the deficiencies in the prior art and provide a flexible watertight through-tank component for high-pressure pipelines and an installation method thereof, so that the hydraulic through-tank pipelines can absorb axial and lateral deformations and ensure that the hydraulic through-tank pipelines will not leak.

[0007] To achieve the above object, the technical solution adopted by the present invention is:

[0008] A flexible watertight passage component for a high-pressure pipeline comprises a passage component body, a guide tube is provided inside the passage component body, a corrugated layer is provided outside the guide tube, a main shell is sleeved on the outer periphery of the corrugated layer, and a sealing assembly is provided between the upper and lower ends of the main shell and the passage component body. The sealing assembly comprises an expansion joint, which is arranged around the outer periphery of the passage component body, one end of the expansion joint is fixedly connected to the passage component body, and the other end is fixedly connected to the main shell, a protective cover is provided on the outer side of the expansion joint, and the protective cover is fixedly connected to the passage component body, a groove is opened circumferentially on the outer side of the corrugated layer, a plurality of buffer pads are fixedly connected to the inner wall of the main shell, and the buffer pads are embedded in the groove, connecting flanges are provided at both ends of the passage component body, and the outer periphery of the main shell is fixedly connected to the watertight bulkhead.

[0009] Preferably, both ends of the expansion joint are fixedly connected to the cabin body and the main shell respectively through fixing clamps.

[0010] Preferably, the protective cover is fixed to the cabin body by screws.

[0011] Preferably, a sealing ring is provided between the chamber body and the connecting flange.

[0012] A method for installing a flexible watertight passage member for a high-pressure pipeline comprises the following steps:

[0013] Step 1: Sleeve the main shell onto the outside of the main body of the chamber, so that the buffer pads on the inner wall of the main shell are embedded in the grooves on the outside of the corrugated layer;

[0014] Step 2: Install the sealing assembly between the upper end of the main shell and the main body of the through-hole. First, install the expansion joint. Secure one end of the expansion joint to the main body of the through-hole with a fixed snap ring, and the other end to the main shell with a fixed snap ring. Then, install the protective cover on the outside of the expansion joint and secure it to the main body of the through-hole with screws.

[0015] Step 3: Insert the main body of the through-hole and the main shell from top to bottom through the through hole in the watertight bulkhead, and repeat the operation in step 2 to install the sealing assembly between the lower end of the main shell and the main body of the through-hole;

[0016] Step 4: Fasten the connection flanges at the upper and lower ends of the through-tank component body to the hydraulic pipes respectively; Step 5: Weld and fix the main shell to the watertight bulkhead to complete the installation of the through-tank component.

[0017] Compared with the prior art, the present invention has the following advantages:

[0018] 1. The combined design of expansion joints and buffer pads effectively absorbs the stress generated by axial expansion and contraction and lateral deformation of high-pressure pipelines, allowing the through-hole components and adjacent pipelines to deform synchronously, thus avoiding the sealing surface leakage problem caused by the rigid connection of traditional fixed through-hole components. The energy absorption effect of the buffer pads and expansion joints reduces fatigue damage to hydraulic pipelines caused by frequent deformation, thereby reducing equipment maintenance frequency and replacement costs.

[0019] 2. The main hull and the watertight bulkhead of the hull structure are welded and sealed, combined with the design of the protective cover and fixed clamp ring, which not only ensures the sealing stability, but also prevents the external environment from physical damage to the expansion joint components, thereby extending the service life of the device.

[0020] 3. The modular design simplifies the installation process and is suitable for the hydraulic pipeline layout requirements under different working conditions, improving the versatility and ease of operation of the device. BRIEF DESCRIPTION OF THE DRAWINGS
