Description

A ship airtight airlock with a sealing ring structure Technical Field

[0001] This utility model belongs to the field of marine facility technology, specifically relating to a marine airtight airlock with a sealing ring structure. Background Technology

[0002] Ships are a common mode of transportation, indispensable in industries such as transport and travel, especially oil tankers, chemical tankers, liquefied gas carriers, passenger ships, and military vessels. Their normal operation and personnel safety highly depend on reliable ventilation systems. Ventilation ducts running through all compartments and decks of the ship also constitute potential channels for the uncontrolled spread of fire, smoke, and hazardous gases within the hull. Therefore, when ventilation ducts need to penetrate critical fireproof bulkheads or bulkheads separating hazardous and safe areas, airtight dampers must be installed to regulate airflow or block airflow and liquid flow. Current airtight dampers mainly employ a structure where the edges of the damper plates interlock and are sealed by a sealing strip, or a structure where sealing strips are installed on the edges of the damper plates and pressed tightly against the edge frame. These structures require considerable closing force to achieve an effective and reliable airtight seal, and the sealing strips and rings used are mostly fixed by bolts or embedded in grooves.

[0003] In existing technologies, such as the "Circular Airtight Wind Gate" provided by Chinese Utility Model Authorization Announcement No. CN205991191U, a circular wind gate body, a gate rod, and a gate plate are included. A worm gear transmission device is provided on the outer circumference of the circular wind gate body. The worm gear transmission device is connected to the gate rod, which is radially inserted into the circular wind gate body. The gate plate is inserted into the gate rod. The back of the gate plate is bolted with one or more layers of rubber sealing rings. A ring of oblique conical gate seat is provided inside the circular wind gate body. The rubber sealing ring of the gate plate is interference-fitted with the oblique conical surface of the gate seat. This structure, which uses the gate plate to be bolted to the rubber sealing ring and the gate seat for fit, is very troublesome to install and operate.

[0004] In view of the aforementioned problems, it is necessary to design a shipboard airtight damper with a sealing ring structure that is simple in structure, low in cost, has good sealing effect, and can be quickly installed.

However, the description of the embodiments is not a limitation on the technical solution. Any formal but not substantive changes made based on the concept of this utility model should be considered within the protection scope of this utility model.

[0021] In the following description, all directional or orientational concepts involving up, down, left, right, front, and back are based on the position shown in Figure 1, and therefore should not be construed as a special limitation on the technical solution provided by this utility model.

[0022] Please refer to Figure 1 and Figure 2, which show an air damper sleeve 1, including an air damper sleeve 1. A gate seat 11 is integrally provided inside the air damper sleeve 1. The gate seat 11 can be fixedly connected to the inner wall of the air damper sleeve 1 by welding. A set of ventilation openings 111 are spaced apart on the gate seat 11. A gate plate 2 is rotatably provided at each of the multiple ventilation openings 111.

[0023] The technical innovation of this utility model lies in the following: a sealing ring 24 is provided around the aforementioned gate plate 2. The sealing ring 24 includes a pair of edgings 241 and a sealing end 242. An air cushion layer 243 is formed inside the sealing end 242. The sealing ring 24 is clamped to the edge of the gate plate 2 by the pair of edgings 241, and the sealing end 242 is mutually sealed with the inner edge of the ventilation opening 111 of the gate seat 11. When the edgings 241 are clamped and fixed to the edge of the gate plate 2, an adhesive layer is added between the contact surfaces of the pair of edgings 241 and the gate plate 2 to improve the fixing strength and further enhance the sealing performance between the sealing ring 24 and the gate plate 2.

[0024] A set of gate bearing seats 21 are provided at intervals on the upper surface of the aforementioned gate plate 2. A shaft 22 is passed through each of the aforementioned gate bearing seats 21. The two ends of the aforementioned shaft 22 are rotatably fixed to the upper surface of the gate seat 11 through bearing seats. The aforementioned gate plate 2 rotates eccentrically on the bearing seats through the gate bearing seats 21 and the shaft 22. When the aforementioned gate plate 2 and the gate seat 11 are in the closed state, the sealing ring 24 is squeezed by the inner edge of the gate plate 2 and the vent 111 to form a sealed connection, and the aforementioned gate plate 2 and the gate seat 11 are located on the same horizontal plane when closed.

[0025] The shape of the aforementioned vent 111 matches the shape of the gate 2, and there is a gap between the aforementioned vent 111 and the gate 2. The aforementioned sealing ring 24 is in an interference fit with the inner edge of the vent 111 within the gap.

[0026] A gate linkage hinge ear 23 is provided on the upper surface of the aforementioned gate plate 2. The gate linkage hinge ears 23 of the aforementioned gate plate 2 are connected by a linkage rod 3. The aforementioned linkage rod 3 is provided with a linkage rod hinge ear 31 at the position corresponding to the gate linkage hinge ear 23. The aforementioned linkage rod hinge ear 31 is connected to the corresponding gate linkage hinge ear 23 by a hinge.

[0027] The opening edge of the aforementioned air damper sleeve 1 is folded with a flange edge 13.

[0028] The thickness of the aforementioned gate plate 2 is the same as the thickness of the aforementioned gate seat 11.

[0029] A limiting plate 12 is provided on the inner wall of the aforementioned damper sleeve 1. The limiting plate 12 is located in the rotation direction of a gate 2 that is close to it. A limiting adjusting screw 121 is provided on the aforementioned limiting plate 12 for limiting the closed position of the aforementioned gate 2. When the aforementioned gate 2 is rotated to be on the same horizontal plane as the valve seat 11, the gate 2 abuts against the aforementioned limiting adjusting screw 121.

[0030] Please refer to Figures 1 and 2. During the installation of the aforementioned sealing ring 24, firstly, an adhesive layer (usually glue) is applied between the pair of edgings 241. Then, the edge of the aforementioned gate plate 2 is inserted between the pair of edgings 241, ensuring a tight fit between the sealing ring 24, the edgings 241, and the gate plate 2. After the glue has set, the aforementioned gate plate 2 is installed onto the bearing seat on the upper surface of the gate seat 11 via the shaft 22. The crew member rotates the aforementioned shaft 22 using an external drive mechanism. The rotation of the aforementioned shaft 22 causes the gate plate 2 connected to it to move eccentrically. Rotate until the gate 2 is inserted into the corresponding vent 111; at the same time, the remaining gates 2 rotate synchronously under the action of the linkage rod 4 and are inserted into the corresponding vent 111. At this time, the sealing end 242 of the aforementioned sealing ring 24 is located between the edge of the gate 2 and the vent 111 and is squeezed and deformed. The aforementioned air cushion layer 243 is squeezed to generate elasticity and maintains a tight fit with the edge of the vent 111, thereby achieving a reliable air seal between the aforementioned gate 2 and the valve seat 11 without the need for closing force, that is, achieving self-sealing.

[0031] In summary, the technical solution provided by this utility model makes up for the shortcomings of the prior art, successfully completes the invention task, and faithfully realizes the technical effects described by the applicant in the above technical effect column.
