Technical Field

[0001] This utility model relates to the field of valve technology, specifically a marine valve with good sealing performance. Background Technology

[0002] Marine valves are devices used to control the pressure, flow rate, and flow direction of fluids in marine pipelines to meet the environmental conditions of ships. Valves are control devices for fluid pipelines, and their basic functions are to connect or disconnect the flow of media in the pipeline, change the flow of media, change the flow direction of media, regulate the pressure and flow rate of media, and protect the normal operation of pipeline equipment.

[0003] An investigation revealed that a Chinese utility model patent (publication number: CN215059492U) discloses a marine valve with good sealing effect, comprising a housing, a sealing sleeve that penetrates and extends into the housing and is fixedly installed on the top of the housing, a valve stem that is rotatably connected to the inner side of the sealing sleeve, two first gear blocks that are fixedly installed on the outer side of the valve stem, two valve plates that are fixedly installed between the inner top wall and the inner bottom wall of the housing, two fixed cylinders that are fixedly installed on opposite sides of the two valve plates, support rods that are fixedly installed on the inner top wall and the inner bottom wall of the fixed cylinders, and a first bearing block that is fixedly installed between the opposite sides of the two support rods corresponding to the top and bottom.

[0004] Although the aforementioned patent improves the valve's sealing effect through a double-layer blocking design, effectively preventing liquid from flowing through the valve and ensuring its normal operation, making it convenient for users to use, the valve lacks buffering during use. This means that when the valve is opened and closed rapidly, the liquid will quickly impact the valve, potentially causing damage to the internal components.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] like Figure 1-6As shown, this utility model provides a marine valve with good sealing effect, including a valve body 1, and a first buffer mechanism 2 and a second buffer mechanism 3 are provided inside the valve body 1. The first buffer mechanism 2 includes a first mounting groove 201, which is located inside one end of the valve body 1. The valve body 1 is connected to the first connecting plate 202 and the second connecting plate 203 respectively through the first mounting groove 201. Multiple connecting grooves 204 are provided on opposite sides of the first connecting plate 202 and the second connecting plate 203. Springs 205 are provided on the inner wall of the connecting grooves 204. A first filter screen 207 is provided in the middle of the first connecting plate 202 and the second connecting plate 203. Multiple connecting blocks 206 are provided on the outer wall of the first filter screen 207. The opposite ends of two springs 205 are connected to the two sides of the same connecting block 206.

[0019] The second buffer mechanism 3 includes a second mounting groove 301, which is located inside the other end of the valve body 1. The valve body 1 is fixedly connected to the mounting plate 302 via the second mounting groove 301. Multiple elastic ropes 303 are equidistantly arranged on one side of the mounting plate 302, and the other ends of the multiple elastic ropes 303 are connected to the corresponding side of the same buffer ring 304. A second filter screen 305 is detachably installed inside the buffer ring 304. The shape of the second filter screen 305 is adapted to the outer diameter of the port of the valve body 1, and the position of the second filter screen 305 corresponds to the position of the first filter screen 207. By setting the second buffer mechanism 3, when the valve is opened, the elastic ropes 303 and the second filter screen 305 can buffer the water flow, avoiding damage to the internal components of the valve body 1 due to the large impact force of the water flow at the moment the valve is opened. Furthermore, the second filter screen 305 can work with the first filter screen 207 to activate the efficiency of multi-stage filtration, ensuring the filtration effect of the valve.

[0020] The valve body 1 is fixedly connected to the valve cover 4 by four fixing nuts. A gate 5 is provided inside the valve body 1. A gate nut 6 is fixedly connected to the top of the gate 5. A valve stem 7 is provided inside the gate nut 6. The shape of the gate nut 6 is adapted to the shape of the valve stem 7.

[0021] Both the valve body 1 and the valve cover 4 have sealing grooves on their opposite surfaces. The valve body 1 and the valve cover 4 are engaged with the sealing ring 8 through the sealing grooves. By setting the sealing ring 8 and the sealing grooves, the sealing ring 8 can ensure the sealing of the connection between the valve body 1 and the valve cover 4.

[0022] The valve stem 7 is rotatably connected to the valve cover 4 via a sealed bearing. A handle 9 is fixedly connected to the outer wall of the valve stem 7. An anti-slip pad is provided on the outer wall of the handle 9. By setting a sealed bearing, the friction generated when the valve stem 7 rotates can be reduced, thus avoiding severe wear caused by repeated rotations of the valve stem 7.

[0023] The shape of the gate 5 is adapted to the shape of the internal pipe of the valve body 1. The valve body 1 has a groove 10 inside, and the gate 5 has an elastic sealing plate 11 inside. The shape of the elastic sealing plate 11 is adapted to the shape of the groove 10. By setting the elastic sealing plate 11 and the groove 10, when the gate 5 moves downward, since the elastic sealing plate 11 and the gate 5 are downward protruding, when the gate 5 overlaps with the inside of the valve body, the elastic sealing plate 11 will be embedded in the groove 10. This allows the valve to ensure the sealing of the connection between the gate 5 and the valve body 1 through multiple layers of sealing, avoiding the situation where the valve is not tightly connected to the gate 5 and the valve body 1, which would lead to valve leakage. This ensures the sealing performance of the valve.

[0024] Working principle: When liquid flows into valve body 1 through water pump, it passes through first filter screen 207 to filter impurities in the liquid. When liquid hits first filter screen 207, the first filter screen 207 is compressed and squeezes spring 205, causing spring 205 to contract. The filtered liquid continues to flow and hits second filter screen 305. When liquid hits second filter screen 305, it compresses elastic rope 303. Through the elastic buffering of second spring 205 and elastic rope 303, the impact force of liquid hitting valve body 1 can be reduced, thereby slowing down the flow rate of water, and the liquid is filtered a second time through the mesh of second filter screen 305.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
