Description

Technical Field

[0001] The utility model relates to the technical field of globe valves, and particularly relates to a marine right-angle stop check valve. Background Technique

[0002] A stop check valve is a multi-purpose valve that combines the functions of a globe valve and a check valve. Its structural form is similar to that of a globe valve, but the valve stem and the valve flap are not fixedly connected. When the valve stem descends and presses the valve flap tightly against the valve seat, it functions as a globe valve; after the valve stem rises, it functions as a check valve. On pipelines that require the installation of a globe valve (or gate valve) and a check valve at the same time (such as the outlet end of a water pump), or in places where the installation position is restricted (such as on a ship), using a stop check valve can save installation costs and space.

[0003] Currently, when a marine right-angle stop check valve is connected and used at a ship pipeline, the pipeline is screwed and installed in the threaded port of the valve body of the right-angle stop check valve with a pipe body provided with a threaded wall. With the long-term use of the right-angle stop check valve, water leakage often occurs at the connection between its valve body and the pipeline. Since most ships are sailing on water, it is not easy for ship maintenance personnel to discover when the right-angle stop check valve leaks, resulting in water leakage hazards to the ship equipment below the right-angle stop check valve. Therefore, we propose a marine right-angle stop check valve. Summary of the Utility Model

[0004] The main purpose of the utility model is to provide a marine right-angle stop check valve, in which a leak detection mechanism is arranged at the check valve body of the marine right-angle stop check valve. The leak detection mechanism is arranged at the check valve body of the marine right-angle stop check valve to form a structure that surrounds the check valve body and the ship pipeline. When water leaks at the connection between the ship pipeline and the check valve body, the water can contact the water contact switch of the water energy lamp at the leak detection mechanism, causing the water energy lamp to light up. At this time, ship maintenance personnel can discover that water leakage has occurred at the check valve body, effectively solving the problems in the background technique.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A marine right-angle stop-check valve includes a check valve body. A side connector and a bottom connector are integrally formed on the side and bottom surfaces of the valve body of the check valve body. It also includes a leak detection mechanism, which includes an L-shaped pressing seat, an L-shaped connecting seat, a rubber sealing tube, a rear sealing plate, a front sealing plate and a water energy lamp. The check valve body and the side connector are externally sleeved with an L-shaped pressing seat, and a vertical guiding hole for passing through the valve stem above the check valve body is provided at the L-shaped pressing seat. The check valve body and the bottom connector are downwardly clamped into the L-shaped connecting seat, and a bottom guiding hole for inserting the bottom connector is provided at the L-shaped connecting seat. A rubber sealing tube for sleeving outside the bottom connector is embedded in the bottom guiding hole. Rear sealing plates and front sealing plates are respectively bonded at the two side openings of the L-shaped connecting seat and the L-shaped pressing seat, and a bottom leak hole for screwing and installing the water energy lamp is downwardly penetrated and provided at the L-shaped connecting seat below the side connector. A plate hole is provided on the surface of the plate body of the front sealing plate facing the side connector.

[0007] Further, a rubber tube is clamped into the plate hole of the front sealing plate, and the outer tube wall of the rubber tube is adhesively fixed to the plate hole of the front sealing plate;

[0008] By adopting the above technical solution, when the side connector is connected to the ship pipeline, the ship pipeline can be inserted into the rubber tube of the front sealing plate for sealed insertion.

[0009] Further, a frustum-shaped sealing sleeve protrudes inside the tube body of the rubber sealing tube, and the small sleeve opening of the frustum-shaped sealing sleeve is sleeved outside the bottom connector;

[0010] By adopting the above technical solution, when the bottom connector is connected to the ship pipeline, the ship pipeline can pass through the frustum-shaped sealing sleeve of the rubber sealing tube to ensure the connection sealing performance between the rubber sealing tube and the ship pipeline.

[0011] Further, U-shaped seat cavities are oppositely provided inside the seat bodies of the L-shaped connecting seat and the L-shaped pressing seat, and the check valve body is clamped into the U-shaped seat cavities of the L-shaped connecting seat and the L-shaped pressing seat;

[0012] By adopting the above technical solution, the L-shaped connecting seat and the L-shaped pressing seat can be sleeved outside the check valve body with the U-shaped seat cavities.

[0013] Further, a threaded hole wall is provided at the hole wall of the bottom leak hole, and the tail seat of the water energy lamp is screwed at the threaded hole wall of the bottom leak hole;

[0014] By adopting the above technical solution, the tail seat of the water energy lamp can be screwed at the threaded hole wall of the bottom leak hole for the installation of the water energy lamp.

[0015] Further, the outer tube wall of the rubber sealing tube is adhesively connected to the inner hole wall of the bottom guiding hole;

[0016] By adopting the above technical solution, the rubber sealing tube is not easy to fall off after being adhesively bonded at the bottom guiding hole.

[0017] Compared with the prior art, the utility model has the following beneficial effects:

[0018] The utility model is provided with a leak detection mechanism at the check valve body of the marine right-angle stop check valve. The leak detection mechanism is provided with a structure that surrounds the check valve body and the ship pipeline at the check valve body of the marine right-angle stop check valve. When the connection between the ship pipeline and the check valve body leaks, water can contact the water contact switch of the water energy lamp at the leak detection mechanism, causing the water energy lamp to light up. At this time, the ship maintenance personnel can find that there is a water leakage problem at the check valve body;

[0019] And the leak detection mechanism can surround the ship pipeline and the check valve body. When the connection between the ship pipeline and the check valve body leaks, water can be collected by the leak detection mechanism, ensuring that before the water leakage at the check valve body is discovered, the ship is not easily damaged by water leakage.

[0026] Among them, a rubber pipe 16 is clamped into the plate hole of the front sealing plate 13, and the outer pipe wall of the rubber pipe 16 is adhesively fixed to the plate hole of the front sealing plate 13;

[0027] By adopting the above technical solution, when the side connection head 2 is connected to the ship pipeline, the ship pipeline can be inserted into the rubber pipe 16 of the front sealing plate 13 for sealed insertion.

[0028] Among them, a frustum-shaped sealing sleeve 10 protrudes inside the pipe body of the rubber sealing pipe 9, and the small sleeve opening of the frustum-shaped sealing sleeve 10 is sleeved outside the bottom connection head 3;

[0029] By adopting the above technical solution, when the bottom connection head 3 is connected to the ship pipeline, the ship pipeline can pass through the frustum-shaped sealing sleeve 10 of the rubber sealing pipe 9 to ensure the connection tightness between the rubber sealing pipe 9 and the ship pipeline.

[0036] It should be noted that the present utility model is a marine right-angle stop check valve.

At this time, when the water energy lamp 15 installed at the L-shaped socket 7 contacts the leaked water, the water contact switch and the reed switch of the water energy lamp 15 are closed, resulting in the conduction of the circuit and the lighting of the water energy lamp 15. At this time, the ship maintenance personnel can find that there is a water leakage problem at the check valve body 1, and then heat the glue at the connection between the L-shaped socket 7 and the L-shaped pressure seat 5 and pull the L-shaped socket 7 and the L-shaped pressure seat 5 forcefully. At this time, the check valve body 1 and the ship pipeline can be exposed for maintenance.
