Description

Technical Field

[0001] The utility model relates to the technical field of ships, in particular to a joint device for a fresh water tank injection pipe of a ship. Background Art

[0002] Currently, filling freshwater tanks at dock requires the use of flanged connectors and filling flanges. Because the ship's freshwater tank filling pipes are curved downward, the flanges must be bolted together, requiring bolt installation every time water is filled. Furthermore, to prevent leakage during filling, gaskets must be placed between the flanges, which then need to be removed after filling is complete. This makes filling cumbersome and inefficient. Utility Model Content

[0003] The utility model aims to provide a connector device for a ship's fresh water tank injection pipe, which is easy to use and has improved efficiency.

[0004] In order to achieve the above-mentioned purpose of the utility model, the joint device of the fresh water tank injection pipe of the utility model adopts the following technical solutions:

[0005] A joint device for a ship's fresh water tank filling pipe comprises a fresh water tank filling pipe, the fresh water tank filling pipe extends out of the main deck and bends downward, an injection port is provided at the bent end of the fresh water tank filling pipe, an injection flange is provided at the position of the injection port, and the fresh water tank filling pipe is assembled with an installation pipe through the injection flange; a mounting flange is provided at one end of the installation pipe, the mounting flange and the injection flange are locked by fasteners, and a sealing gasket is provided between the mounting flange and the injection flange; a fire-fighting joint is provided at the other end of the installation pipe, and the fire-fighting joint is threadedly connected to the installation pipe; a seal is detachably installed on one end of the installation pipe that is connected to the fire-fighting joint, and the seal is made of elastic rubber material, and the seal comprises an extrusion portion and a connecting portion, and the connecting portion is configured as a sleeve structure , the inner wall of the connecting part is provided with multiple support rings at intervals along its length direction, and a spacing is left between two adjacent support rings, and the support ring is made of a rigid material; the mounting pipe is provided with an inner mounting groove for mounting the connecting part, and the groove wall of the inner mounting groove is provided with a first internal thread, and the outer wall of the connecting part is provided with a first external thread adapted to the first internal thread, and the first external thread is made of an elastic rubber material; one end of the connecting part contacts the bottom of the inner mounting groove, and the other end of the connecting part is provided with an extrusion part, and the connection between the extrusion part and the connecting part forms a step structure, and the end face of the mounting pipe is provided with an outer mounting groove for matching the extrusion part, and the diameter of the outer mounting groove is larger than the diameter of the inner mounting groove; the fire joint is provided with a sealing ring at one end of the mounting pipe for docking, and the sealing ring is in contact with the extrusion part.

[0006] Preferably, the angle between the end face of the fresh water tank injection pipe at the injection port and the main deck is 145 degrees.

[0007] Preferably, the installation connecting pipe is configured as a straight pipe, which is fixed to the installation flange by welding.

[0008] Preferably, one end of the mounting pipe for docking with the fire connector is provided with a second external thread, and the fire connector is provided with a second internal thread, and the second internal thread is adapted to the second external thread.

[0009] Preferably, the sealing gasket and the sealing ring are both made of rubber.

[0010] Compared with the prior art, the beneficial effects of the present invention are:

[0011] 1. The utility model pre-installs the installation pipe on the injection flange through the installation flange. The installation pipe can be installed on the fresh water tank injection pipe without disassembly. When the fresh water tank needs to be filled with fresh water, it is only necessary to screw the fire connector on the installation pipe and connect the fire hose through the fire connector to start fresh water filling. The overall operation is simple, quick to install and remove, and improve efficiency.

[0012] 2. The utility model improves the sealing performance by providing a sealing member, and is less likely to leak at the location where the fire-fighting joint butts against the installation pipe. When the fire-fighting joint is connected to the installation pipe, the sealing ring inside the fire-fighting joint and the extrusion portion of the sealing member are in pressure contact, and the elasticity of the sealing member and the sealing ring complement each other. For example, when the elasticity of the sealing ring is damaged, the elasticity of the sealing member can compensate, thereby ensuring the sealing effect of the butt joint between the sealing ring and the sealing ring.

[0013] 3. The connection part of the present invention is threadedly connected to the inner wall of the installation pipe, and the seal can be disassembled and installed by rotating. The seal is easy to disassemble and install. In actual use, the seal can be always installed on the installation pipe without disassembly. Moreover, since the first external thread on the outer wall of the connection part is made of elastic rubber material, when the fire-fighting joint is tightened on the installation pipe, the sealing ring presses against the extrusion part and drives the connection part to be compressed and deformed at the same time. Under the action of the support ring, the first external thread and the first internal thread are tightly fitted. Moreover, the multiple support rings arranged at intervals facilitate the compression and deformation of the connection part. Under the action of force, the first external thread of the connection part is pressed against the groove wall of the first internal thread. Therefore, through the setting of this structure, not only the installation of the connection part and the inner wall of the installation pipe is provided, but also the sealing between the connection part and the inner wall of the installation pipe is guaranteed, and leakage is not easy to occur when fresh water is injected.
