[0001] The utility model relates to the technical field of marine valves, in particular to a marine valve with a lockable hand wheel. Background Art

[0002] Marine valves are valves specially designed for use in ship systems to meet the special needs and requirements of the offshore environment. These valves usually need to undergo rigorous design and testing to ensure that they can operate in the marine environment for a long time without being affected by corrosion, seawater erosion or other harsh conditions.

[0003] The valve stem of a marine valve is usually rotated by a handwheel. Since the ship will experience bumps and vibrations during its travel, the handwheel may become loose, thus affecting the normal use of the valve. Utility Model Content

[0004] The utility model aims to provide a marine valve with a lockable hand wheel, so as to solve the problem in the background art that the hand wheel may become loose due to the bumps and vibrations generated during the sailing of the ship, thereby affecting the normal use of the valve.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: a marine valve with a lockable handwheel: comprising a valve body, a flange fixedly connected to the surface of the valve body, a valve stem seat fixedly installed on the surface of the valve body, the valve stem body rotatably connected to the surface of the valve stem seat, a first gear fixedly connected to the top of the valve stem body, a working box fixedly connected to the surface of the valve stem seat, a bearing fixedly installed on the surface of the working box, a rotating rod rotatably connected to the surface of the bearing, a second gear fixedly connected to the bottom of the rotating rod, a limiting disk fixedly connected to the surface of the rotating rod, a limiting hole is provided on the surface of the limiting disk, a handwheel body is fixedly connected to the top of the rotating rod, an anti-skid column is fixedly connected to the surface of the handwheel body, a fixing nut is fixedly connected to the surface of the valve body, a limiting bolt is threadedly connected to the surface of the fixing nut, and the limiting bolt is inserted into the limiting hole.

[0006] Preferably, the working box is hollow inside and a circular hole is opened at the bottom of the working box. The working box is fixedly connected to the valve stem seat through the circular hole. The top of the valve stem body and the first gear and the second gear are located inside the working box.

[0007] Preferably, the first gear and the second gear are at the same level, two groups of second gears are provided, and the second gears are located on both sides of the first gear, and the first gear is meshed with the two groups of second gears at the same time.

[0008] Preferably, the diameter of the second gear is smaller than the diameter of the first gear.

[0009] Preferably, the rotating rod rotates on the working box through a bearing, and the second gear, the limiting plate and the handwheel body rotate synchronously with the rotating rod.

[0010] Preferably, the limiting holes are provided in a plurality of groups and are evenly arranged in a ring shape on the limiting plate, and the anti-slip columns are provided in a plurality of groups and are evenly arranged in a ring shape on the handwheel body.

[0011] Preferably, the position of the limiting bolt on the working box is adjusted by a fixing nut, and the limiting bolt limits the rotation of the limiting plate on the working box through the limiting hole.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The marine valve adjusts the position of the limit bolt on the operating box by rotating the limit bolt on the fixing nut. The limit bolt is inserted into the limit hole. The limit bolt limits the rotation of the limit plate on the operating box through the limit hole. The limit plate limits the rotation of the second gear and the handwheel body through the rotating rod, thereby preventing the valve stem body and the first gear from rotating. The valve stem body is locked and cannot rotate, thereby avoiding the influence of ship bumps and ensuring the normal use of the valve body.

[0014] 2. The marine valve is provided with two sets of handwheel bodies and second gears. Two workers can be used to rotate the handwheel bodies. The handwheel bodies drive the second gears to rotate inside the working box through the rotating rod. The second gears drive the valve stem bodies to rotate on the valve stem seats through the first gears, so that the valve stem bodies are rotated through the handwheel bodies. Moreover, the diameter of the second gear is smaller than that of the first gear. In the process of the handwheel bodies driving the second gears to rotate through the rotating rod, the workers can save more effort in the process of rotating the handwheel bodies, and the probability of failing to rotate the valve stem bodies is reduced.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-5 , an embodiment provided by the utility model:

[0023] A marine valve with a lockable hand wheel comprises a valve body 1, a flange 2 is fixedly connected to the surface of the valve body 1, a valve stem seat 3 is fixedly installed on the surface of the valve body 1, a valve stem body 4 is rotatably connected to the surface of the valve stem seat 3, a first gear 5 is fixedly connected to the top of the valve stem body 4, a work box 6 is fixedly connected to the surface of the valve stem seat 3, a bearing 7 is fixedly installed on the surface of the work box 6, a rotating rod 8 is rotatably connected to the surface of the bearing 7, a second gear 9 is fixedly connected to the bottom of the rotating rod 8, a limit plate 10 is fixedly connected to the surface of the rotating rod 8, a limit hole 11 is provided on the surface of the limit plate 10, a hand wheel body 12 is fixedly connected to the top of the rotating rod 8, and the hand wheel body 1 2 is fixedly connected with an anti-skid column 13, a fixing nut 14 is fixedly connected to the surface of the valve body 1, a limiting bolt 15 is threadedly connected to the surface of the fixing nut 14, and the limiting bolt 15 is inserted into the limiting hole 11. The marine valve can limit the handwheel body 12 from continuing to rotate when the handwheel body 12 is not in use, thereby preventing the handwheel body 12 from rotating under the turbulence of the ship, ensuring the normal use of the valve body 1, and at the same time, two groups are provided on the handwheel body 12, so that two people can rotate the valve stem at the same time, and the second gear 9 is provided inside the working box 6 to drive the first gear 5 to rotate, so that the handwheel body 12 is more labor-saving during the rotation process.

[0024] Furthermore, the interior of the working box 6 is hollow, and a circular hole is opened at the bottom of the working box 6. The working box 6 is fixedly connected to the valve stem seat 3 through the circular hole. The top of the valve stem body 4 and the first gear 5 and the second gear 9 are located inside the working box 6. The first gear 5 and the second gear 9 will not be disturbed by the outside world during the rotation, thereby ensuring the stability of the rotation of the first gear 5 and the second gear 9.

[0025] Furthermore, the first gear 5 and the second gear 9 are at the same horizontal height, two groups of second gears 9 are provided, and the second gears 9 are located on both sides of the first gear 5, and the first gear 5 is meshed with the two groups of second gears 9 at the same time, and the two groups of second gears 9 can drive the first gear 5 to rotate, thereby increasing the power source for driving the first gear 5 to rotate.

[0026] Furthermore, the diameter of the second gear 9 is smaller than the diameter of the first gear 5 , and the handwheel body 12 can save more effort when driving the second gear 9 to rotate through the rotating rod 8 .

[0027] Furthermore, the rotating rod 8 rotates on the working box 6 through the bearing 7, and the second gear 9, the limit plate 10 and the handwheel body 12 rotate synchronously with the rotating rod 8. When the limit plate 10 stops rotating, the limit plate 10 will stop the rotation of the limit plate 10 and the second gear 9 through the rotating rod 8, thereby preventing the first gear 5 and the valve stem body 4 from rotating.

[0028] Furthermore, multiple groups of limiting holes 11 are provided and are evenly arranged in a ring shape on the limiting plate 10, and multiple groups of anti-skid columns 13 are provided and are evenly arranged in a ring shape on the handwheel body 12. The anti-skid columns 13 can prevent workers from slipping when turning the handwheel body 12, thereby improving the comfort of workers turning the handwheel body 12.

[0029] Furthermore, the position of the limit bolt 15 on the working box 6 is adjusted by the fixing nut 14, and the limit bolt 15 limits the rotation of the limit plate 10 on the working box 6 through the limit hole 11. At this time, the handwheel body 12 is locked on the working box 6 and will not be affected by the turbulence of the ship.

[0030] Working principle: The limit bolt 15 is rotated on the fixing nut 14 to adjust the position of the limit bolt 15 on the working box 6, and the limit bolt 15 is inserted into the limit hole 11. The limit bolt 15 limits the rotation of the limit plate 10 on the working box 6 through the limit hole 11. The limit plate 10 limits the rotation of the second gear 9 and the handwheel body 12 through the rotating rod 8, thereby preventing the valve stem body 4 and the first gear 5 from rotating. The valve stem body 4 is locked and cannot rotate, thereby avoiding the influence of ship bumps.

[0031] The handwheel body 12 drives the second gear 9 to rotate inside the work box 6 through the rotating rod 8. The second gear 9 and the handwheel body 12 are each provided with two groups, so that the handwheel body 12 can be operated by two workers, and the diameter of the second gear 9 is smaller than the diameter of the first gear 5. The handwheel body 12 can save more effort in the process of driving the second gear 9 to rotate through the rotating rod 8. The second gear 9 drives the valve stem body 4 to rotate on the valve stem seat 3 through the first gear 5, thereby completing the rotation of the valve stem body 4 through the handwheel body 12.
