Description

Technical Field

[0001] The utility model relates to the technical field of globe valves, in particular to a marine right-angle globe valve. Background Art

[0002] A marine right-angle globe valve is a specially designed valve used to control the flow direction and flow rate of liquids in a ship system. The design of the marine right-angle globe valve ensures that the directions of liquid entering and leaving the valve form a 90-degree angle. This design makes the valve particularly effective in an environment with limited space. The right-angle globe valve controls the flow of fluid through a plug-shaped valve flap, and the valve flap moves linearly along the center line of the fluid to open or close the flow passage. When fully opened, the valve flap is lifted to a certain height to allow the fluid to pass freely; when closed, the valve flap descends to block the flow passage and prevent the fluid from flowing.

[0003] In the process of using the existing globe valves, although there are many benefits, there are still the following problems. The protection of the globe valve is not perfect enough, resulting in liquid splashing onto the surface of the valve stem of the globe valve, eroding the threads on the surface of the valve stem and being prone to rusting. Moreover, during the handling of external equipment, it will collide with the valve stem of the globe valve, causing the valve stem to bend and affecting the smooth use of the valve stem. Summary of the Utility Model

[0004] In view of the problems in the prior art, the utility model provides a marine right-angle globe valve.

[0005] The technical solution adopted by the utility model to solve its technical problems is a marine right-angle globe valve, which includes a valve body main body, a fixing block, a sealing seat and a cover plate.

Circularly arrayed clamping sleeves are installed on the upper outer wall of the baffles. A cover plate is arranged on the upper outer wall of the baffles. Sealing gaskets are fixedly attached to both outer walls of the baffles.

[0006] By adopting the above technical solution, the valve handle meshes with the valve stem, driving the valve stem to move vertically relative to each other. Thus, the valve stem drives the valve flap inside the valve body main body to move. After the baffle is driven to rotate by the staff, it can form a cylindrical shape outside the valve stem and cooperate with the sealing gasket to shield the valve stem.

[0007] Specifically, a liquid outlet pipe is inserted and installed on one side of the outer wall of the lower end of the valve body main body. A liquid inlet pipe is inserted and installed on one side of the outer wall of the valve body main body.

[0009] Specifically, one side of the outer wall of the upper end of the sealing seat is rotatably installed with a valve handle, and the valve handle is threadedly connected to the valve stem.

[0010] By adopting the above technical solution, when the staff manually rotates the valve handle, it can drive the valve stem to move vertically relatively, achieving the purpose of adjusting the working position of the valve flap inside the valve body and achieving the purpose of controlling the on-off inside the valve body.

[0011] Specifically, the fixing block is designed in a circular ring shape, and bolts are arranged in a circular array inside the fixing block, and the fixing block is connected to the sealing seat through the bolts.

[0012] By adopting the above technical solution, the bolts can connect the fixing block and the sealing seat, maintaining the position stability of the fixing block outside the sealing seat and ensuring the relatively stable use position of the baffle.

[0013] Specifically, a connecting block is installed at the lower end of the outer wall of one side of the baffle, and the connecting block is rotatably installed inside the ferrule.

[0014] By adopting the above technical solution, the baffle can rotate circumferentially around the ferrule as the center through the connecting block, realizing the controlled shielding of the valve stem.

[0015] Specifically, the baffle is designed in an arc shape, and one side of the baffle is located inside the cover plate, and the working height of the cover plate is higher than the upper end face of the valve stem.

[0016] By adopting the above technical solution, the baffle forms a cylindrical shape after combination, so that the baffle can shield and protect the valve stem, and the cover plate can limit the baffle, maintaining the relative stability of the use position of the baffle.

[0017] Specifically, a sleeve is installed on one side of the upper end of the inner wall of the cover plate, the sleeve is located outside the valve stem, and a handle is installed on one side of the upper end outer wall of the cover plate.

[0018] By adopting the above technical solution, the sleeve and the valve stem keep the use position of the cover plate stable, and the staff can lift the cover plate through the handle, which is convenient for disassembling the cover plate.

[0029] In order to make the technical means, creative features, achieved purposes, and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0030] In order to save manpower and improve efficiency, as an embodiment of the present utility model, such as Figure 1 、Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown in Figure 5 , a marine right-angled globe valve of the present utility model includes a valve body main body 1, a fixing block 2, a sealing seat 13 and a cover plate 26. A sealing seat 13 is provided on the outer wall of the upper end of the valve body main body 1. A valve rod 14 is provided inside the sealing seat 13. A fixing block 2 is provided on the outer wall of the sealing seat 13. Circularly-arrayed baffles 24 are provided on the outer wall of the upper end of the fixing block 2. Circularly-arrayed bushings 22 are installed on the upper outer wall of the baffles 24. A cover plate 26 is provided on the upper outer wall of the baffles 24. Sealing gaskets 25 are fixedly attached to both outer walls of the baffles 24.

[0031] During use, the valve handle 15 meshes with the valve rod 14, driving the valve rod 14 to move vertically relative to each other. Thus, the valve rod 14 drives the valve flap inside the valve body main body 1 to move. After the baffles 24 are driven to rotate by the staff, a cylindrical shape can be formed outside the valve rod 14, and the valve rod 14 is shielded in cooperation with the sealing gaskets 25.

[0032] For the flow of the medium, by way of example, as Figure 1 shown, a liquid outlet pipe 11 is inserted and installed on one side of the outer wall of the lower end of the valve body main body 1. A liquid inlet pipe 12 is inserted and installed on one side of the outer wall of the valve body main body 1. Both the liquid outlet pipe 11 and the liquid inlet pipe 12 are communicated with the inside of the valve body main body 1. Flanges are installed on one side of the outer walls of both the liquid outlet pipe 11 and the liquid inlet pipe 12.

[0033] During use, the liquid medium enters the inside of the valve body main body 1 through the liquid inlet pipe 12, and the liquid medium inside the valve body main body 1 is discharged through the liquid outlet pipe 11. The controlled flow of the liquid medium is ensured by the valve flap inside the valve body main body 1. The liquid outlet pipe 11 and the liquid inlet pipe 12 can be connected to an external pipeline through the flanges.

[0034] For the controlled flow of the medium, by way of example, as Figure 2 shown, a valve handle 15 is rotatably installed on one side of the outer wall of the upper end of the sealing seat 13. The valve handle 15 is threadedly connected to the valve rod 14.

[0035] During use, when the staff manually rotates the valve handle 15, it can drive the valve rod 14 to move vertically relative to each other, achieving the purpose of adjusting the working position of the valve flap inside the valve body main body 1 and achieving the purpose of controlling the on-off inside the valve body main body 1.

[0036] For fixing the fixing block 2, by way of example, as Figure 3 shown, the fixing block 2 is designed in a circular ring shape. Circularly-arrayed bolts 21 are provided inside the fixing block 2, and the fixing block 2 is connected to the sealing seat 13 through the bolts 21.

[0037] During use, the bolt 21 can connect the fixed block 2 and the sealing seat 13, maintaining the positional stability of the fixed block 2 outside the sealing seat 13 and ensuring the relatively stable use position of the baffle 24.

[0038] For the baffle 24 to rotate, by way of example, as Figure 3 shown, a connecting block 23 is installed at the lower end of the outer wall on one side of the baffle 24, and the connecting block 23 is rotatably installed inside the ferrule 22.

[0039] During use, the baffle 24 can rotate circumferentially around the ferrule 22 through the connecting block 23, realizing the controlled occlusion of the valve stem 14.

[0040] To protect the valve stem 14, by way of example, as Figure 4 shown, the baffle 24 is designed in a circular arc shape, and one side of the baffle 24 is located inside the cover plate 26, and the working height of the cover plate 26 is higher than the upper end face of the valve stem 14.

[0041] During use, the baffle 24 forms a cylindrical shape after combination, so that the baffle 24 can occlude and protect the valve stem 14, and the cover plate 26 can limit the baffle 24, maintaining the relative stability of the use position of the baffle 24.

[0042] To limit the baffle 24, by way of example, as Figure 4 shown, a sleeve 28 is installed on one side of the upper end of the inner wall of the cover plate 26. The sleeve 28 is located outside the valve stem 14, and a handle 27 is installed on one side of the upper end outer wall of the cover plate 26.

[0043] During use, the sleeve 28 and the valve stem 14 keep the use position of the cover plate 26 stable, and the staff can lift the cover plate 26 through the handle 27, facilitating the disassembly of the cover plate 26.

[0044] When the present utility model is in use, the staff manually rotates the valve handle 15. Through the meshing of the valve handle 15 and the valve stem 14, the valve stem 14 is driven to move vertically relative, so that the valve stem 14 drives the valve flap inside the valve body main body 1 to move, achieving the purpose of controlling the controlled communication inside the valve body main body 1;

[0045] The liquid enters the valve body main body 1 through the liquid inlet pipe 12 and is discharged through the liquid outlet pipe 11 in a controlled manner, achieving the purpose of controlling the flow of the liquid.

[0046] The staff takes a wrench to rotate the bolt 21 to fix the fixing block 2. And the staff manually rotates the baffle 24, so that the baffle 24 makes a circular rotation through the ferrule 22 and the connecting block 23. A shielding surface is formed by the combined baffle 24 and the gasket 25 to shield the sealing seat 13, the valve stem 14 and the valve handle 15, avoiding the contact between the external liquid or object and the valve stem 14, achieving the purpose of protecting the sealing seat 13, the valve stem 14 and the valve handle 15;

[0047] The staff takes the cover plate 26 and places it outside the baffle 24. The sleeve 28 and the valve stem 14 keep the position of the cover plate 26 stable, and the cover plate 26 restricts the position of the baffle 24 to prevent the baffle 24 from rotating.
