Description

Technical Field

[0001] The present application relates to the field of shipbuilding technical equipment, and in particular to a deck water-sealed non-return leakage outlet suitable for ships. Background Art

[0002] When constructing areas on ships, multiple leaks are usually designed to share a main pipeline for discharging sewage such as gray water or black water. These leaks need to be equipped with devices to prevent gas backflow to ensure the air quality inside the ship and the health of the crew. In addition, preventing liquid backflow usually relies on the slope of the pipeline or adding a check device, but in some special cases, such as car carriers, due to the limited space for pipeline layout, it is impossible to tilt the pipeline or add a check device, which brings challenges to the anti-backflow measures.

[0003] On ships with limited space, such as car carriers, the design and layout of pipelines requires comprehensive consideration of factors such as pipeline tilting, non-return devices and maintenance. Since the pipeline cannot be tilted, adding a non-return device may not effectively solve the problem of liquid backflow, and maintenance will also become difficult. Summary of the invention

DETAILED DESCRIPTION

[0024] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0025] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0026] When constructing areas on ships, multiple leaks are usually designed to share a main pipeline for discharging sewage such as gray water or black water. These leaks need to be equipped with devices to prevent gas backflow to ensure the air quality inside the ship and the health of the crew. In addition, preventing liquid backflow usually relies on the slope of the pipeline or adding a check device, but in some special cases, such as car carriers, due to the limited space for pipeline layout, it is impossible to tilt the pipeline or add a check device, which brings challenges to the anti-backflow measures.

[0027] On ships with limited space, such as car carriers, the design and layout of pipelines requires comprehensive consideration of factors such as pipeline tilting, non-return devices and maintenance. Since the pipeline cannot be tilted, adding a non-return device may not effectively solve the problem of liquid backflow, and maintenance will also become difficult.

[0028] In order to effectively prevent the backflow of gas and low-pressure liquid, the present application provides a deck water-sealed non-return leakage outlet suitable for ships.

[0029] The following is combined with Figure 1-3 This application is described in further detail.

[0030] The present application embodiment discloses a deck water-sealed non-return leakage outlet suitable for ships. Figure 1 , Figure 2 A deck water-sealed non-return water leakage outlet suitable for ships includes a shell 1, which is a cylindrical structure, and a liquid inlet component 2 is arranged at the top of the shell 1, and the liquid inlet component 2 is relatively connected to the inside of the shell 1, and the external medium can enter the inside of the shell 1 through the liquid inlet component 2. A discharge component 5 is also arranged at the bottom of the shell 1, and the discharge component 5 is used to discharge the medium located inside the shell 1.

[0031] The housing 1 is provided with a gravity check assembly 3 below the liquid inlet assembly 2. The interior of the gravity check assembly 3 is relatively connected to the liquid inlet assembly 2. The medium entering from the liquid inlet assembly 2 enters the interior of the gravity check assembly 3, and enters the interior of the housing 1 after the bottom end of the gravity check assembly 3 is opened. The bottom end of the housing 1 is provided with a water seal assembly 4, which can form a water seal area 11 inside the housing 1, thereby reducing the backflow of gas in the connecting pipeline to the space where the water leak is located.

[0032] The liquid inlet assembly 2 includes a grille 21, which is a structure adapted to the top of the shell 1. The grille 21 is fixedly connected to the shell 1 by bolts, and in some embodiments, the side wall of the grille 21 is relatively fixed to the shell 1 by countersunk bolts, and the top of the countersunk bolts is flush with the top wall of the grille 21.

[0033] A liquid inlet hole 22 is vertically provided on the grille 21, and the liquid inlet hole 22 completely penetrates the side wall of the grille 21, thereby connecting the outside with the inside of the shell 1, and the outside medium can enter the inside of the shell 1 through the liquid inlet hole 22. The liquid inlet hole 22 provided on the grille 21 plate meets the flow area ratio of the discharge pipe diameter.

[0034] The gravity check assembly 3 includes a support ring 31, which is coaxially arranged with the housing 1, and the top of the support ring 31 is fixedly connected with the grille 21. The support ring 31 includes a first section 311 fixedly connected with the grille 21 and a second section 312 located at the bottom of the first section 311, the first section 311 is vertically arranged, and the second section 312 is horizontally arranged, the first section 311 and the second section 312 are fixedly connected, and the second section 312 is located at the bottom of the first section 311 and retracts inwardly, so that a guide platform is formed between the first section 311 and the second section 312.

[0035] A check housing 32 is coaxially arranged inside the second subsection 312 of the support ring 31. The check housing 32 is a cylindrical structure, and the outer wall of the check housing 32 is threadedly connected to the second subsection 312. A check port is provided at the bottom end of the check housing 32, and the check port is connected to the inside of the check housing 32. An escape area 321 is provided on one side wall of the check housing 32, and the escape area 321 is inclined toward the inner side of the check housing 32, so that the bottom opening of the check housing 32 is smaller than the top opening.

[0036] The non-return housing 32 is fixedly connected with a hinge plate 33 at the position of the avoidance area 321. The hinge plate 33 is vertically arranged, and the bottom end of the hinge plate 33 is flush with the bottom wall of the non-return housing 32. The bottom end of the hinge plate 33 is hingedly provided with a sealing plate 34, and the sealing plate 34 is divided into a closed part 341 close to the non-return opening at the bottom end of the non-return housing 32 and a counterweight part 342 away from the non-return opening by the hinge plate 33. There is a gap between the bottom end of the sealing plate 34 and the water seal assembly 4 to facilitate the rotation of the sealing plate 34.

[0037] The closing portion 341 of the sealing plate 34 is a plate-shaped structure matching the non-return opening. The non-return opening at the bottom end of the non-return shell 32 is closed by the closing portion 341 , thereby separating the interior of the non-return shell 32 from the interior of the housing 1 .

[0038] A counterweight block 35 is fixedly connected to one side of the counterweight portion 342 of the sealing plate 34 . The counterweight block 35 and the sealing portion 341 are respectively located on both sides of the hinge plate 33 , so that the gravity of the counterweight block 35 drives the sealing portion 341 to close the check port.

[0039] When the external medium enters the inside of the check housing 32 through the grille 21, and the gravity of the medium inside the check housing 32 is greater than the opening gravity of the closing part 341, the closing part 341 rotates downward to connect the inside of the check housing 32 with the inside of the shell 1, and the medium inside the check housing 32 enters the inside of the shell 1. After the medium inside the check housing 32 is discharged, the gravity above the closing part 341 is less than the opening gravity of the closing part 341, and the closing part 341 rotates upward to close the check port, thereby reducing the backflow of the liquid inside the shell 1.

[0040] The discharge assembly 5 includes a discharge shell 51, which is cylindrical and fixedly connected to the bottom wall of the shell 1. The discharge shell 51 is located inside the shell 1, and the top side wall of the discharge shell 51 is higher than the upper surface of the bottom wall of the shell 1, so that a water seal area 11 is formed between the outer side wall of the discharge shell 51 and the inner side wall of the shell 1.

[0041] Reference Figure 1 , Figure 3The water seal assembly 4 includes a water seal rod 41 fixed on the top wall of the discharge shell 51. The water seal rod 41 is arranged horizontally and along the radial direction of the discharge shell 51. A water seal support rod 42 is vertically arranged at the top of the water seal rod 41. The water seal support rod 42 is coaxially arranged with the discharge shell 51, and the water seal support rod 42 is threadedly connected with the water seal rod 41.

[0042] A water seal cover 43 is fixedly connected to the top of the water seal rod 41, and the water seal cover 43 is coaxially arranged with the discharge shell 51. The water seal cover 43 includes a horizontal plate 431 at the top, and a side plate 432 is coaxially fixedly connected to the bottom end of the horizontal plate 431, and the bottom end of the side plate 432 is lower than the top of the discharge shell 51, and a gap is left between the inside of the water seal cover 43 and the outside of the discharge shell 51 to form a water seal flow channel 12, and the water seal flow channel 12 is relatively connected with the water seal area 11.

[0043] In some embodiments, the housing 1, the grille 21, and the water seal cover 43 are made of carbon structural steel, and the countersunk screws and the self-weight waterproof components are made of tin brass.
