Technical Field

[0001] The utility model relates to the technical field of valve bodies, in particular to a marine duplex stainless steel gate valve body. Background Technique

[0002] Marine valves are devices used to control the pressure, flow rate, and flow direction of fluids in ship pipelines to meet the ship's environmental conditions. A valve is a control device for fluid pipelines, and its basic functions are to connect or cut off the flow of pipeline media, change the flow of media, change the flow direction of media, adjust the pressure and flow rate of media, and protect the normal operation of pipeline equipment.

[0003] The Chinese utility model patent with the patent application number 202322891877.1 provides a high-pressure stainless steel gate valve. By setting an adjustment device, it is convenient to adjust the connection part of the high-pressure stainless steel gate valve, which can effectively reduce the situation that the high-pressure stainless steel gate valve cannot be installed due to inaccurate reserved dimensions between pipelines during the installation of the existing high-pressure stainless steel gate valve, affecting the installation efficiency of the high-pressure stainless steel gate valve, and thus improving the overall practicality of the equipment.

[0004] However, it is found during the use of the above equipment that during long-term use, the convex blocks on the gate valve are relatively prominent and are easily collided or scratched by external objects, resulting in damage or fracture, and then making it difficult for the operator to control the rotation of the ring. Content of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the utility model provides a marine duplex stainless steel gate valve body, which solves the problem that the convex blocks on the gate valve in the background technique are relatively prominent and are easily collided or scratched by external objects, resulting in damage or fracture.

[0006] To achieve the above purposes, the utility model is realized through the following technical solutions: A marine duplex stainless steel gate valve body includes a valve body and a valve stem. Extension pieces are connected to both ends of the valve body. A plurality of connection holes are arrayed on the extension pieces, and the connection holes are adapted to connection blocks. The connection blocks are in screw connection with screw rods. An adjustment assembly is installed on the valve body. The adjustment assembly includes a rotating frame. The bottom of the rotating frame is fixedly connected to the screw rod. Two symmetrically arranged handle grips are rotatably connected to the top ends of the rotating frame. The handle grips are semi-circular. A first magnet is fixedly arranged on one side of the handle grip. A second magnet is fixedly installed on the top of the rotating frame. The first magnet corresponds to the second magnet.

[0007] Preferably, inclined surfaces are arranged on both sides of the rotating frame, the inclined surfaces correspond to the handle grips, and a limiting hole is opened in the rotating frame.

[0008] Preferably, a limiting component is arranged on the valve body. The limiting component includes a limiting rod which is L-shaped, and one end of the limiting rod is adapted to the limiting hole.

[0009] Preferably, the limiting rod slides through a limiting frame which is fixed on the valve body. A moving groove is formed in the limiting frame and corresponds to the limiting rod. The width of the moving groove is the same as the diameter of the limiting rod.

[0010] Preferably, a moving plate is slidably installed in the moving groove. The moving plate is adapted to the interior of the limiting frame. One side of the moving plate is connected with a spring, and the moving plate is connected with the inner wall of the limiting frame through the spring.

[0011] Preferably, the limiting rod penetrates through the middle of the moving plate, and the limiting rod is rotatably connected with the moving plate. A limiting ring is fixedly installed on the limiting rod and is located on the side of the moving plate close to the spring.

[0012] The utility model provides a marine duplex stainless steel gate valve body, which has the following beneficial effects:

[0013] (1). By arranging a rotatable handle, when the handle is not needed, the handle is attached to the surface of the rotating frame by the correspondence and magnetic connection of magnet one and magnet two, avoiding the handle being too prominent and reducing the risk of accidental collision and scratching of the handle.

Detailed implementation manner

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Embodiment 1: Please refer to Figures 1-4 , a marine duplex stainless steel gate valve body, including a valve body 1 and a valve stem 2. Extension pieces 3 are connected to both ends of the valve body 1. A plurality of connecting holes 31 are arranged in an array on the extension piece 3. The connecting holes 31 are adapted to the connecting block 32. The connecting block 32 is screwed to the screw rod 33. An adjusting assembly 4 is installed on the valve body 1. The adjusting assembly 4 includes a rotating frame 41. The bottom of the rotating frame 41 is fixedly connected to the screw rod 33. Two symmetrical handles 43 are rotatably connected to the top ends of the rotating frame 41. The handle 43 is semicircular. A first magnet 44 is fixedly arranged on one side of the handle 43. A second magnet 46 is fixedly installed on the top of the rotating frame 41. The first magnet 44 corresponds to the second magnet 46;

[0023] Inclined surfaces 45 are arranged on both sides of the rotating frame 41. The inclined surfaces 45 correspond to the handle 43. A limiting hole 47 is opened in the rotating frame 41.

[0024] Specifically, the rotation of the rotating frame 41 drives the screw rod 33 to rotate. Furthermore, through the screw connection between the screw rod 33 and the connecting block 32, the connecting block 32 can enter the corresponding connecting hole 31 under the rotation of the screw rod 33, thereby realizing the adjustment of the length of the extension piece 3. The semicircular handle 43 is convenient for grasping and operation. When the handle 43 is not needed, the magnetic connection between the first magnet 44 and the second magnet 46 makes the handle 43 fit the surface of the rotating frame 41, which can avoid accidental touching and causing misoperation of the valve. At the same time, the fitting state can protect the handle 43 from external impacts, scratches and other damages;

[0025] The fitting of the handle 43 and the rotating frame 41 is realized by the magnetic connection between the magnet one 44 and the magnet two 46. Without additional mechanical fixing devices, through natural magnetic adsorption, the storage and deployment operations of the handle 43 are extremely simple. The operator can quickly pull up the handle 43 when it is needed, and let it automatically fit the rotating frame 41 when it is not needed, saving operation time and energy. A certain angle is formed between the inclined surface 45 and the handle 43, which is convenient for the operator to more effectively utilize the strength of the hand to rotate the handle 43, reducing the strength and time required for operation and improving operation efficiency.

[0026] Embodiment 2: To avoid the problem of accidental rotation of the rotating frame 41 due to factors such as vibration, please refer to Figures 1-4 , on the basis of Embodiment 1, a limiting component 5 is arranged on the valve body 1. The limiting component 5 includes a limiting rod 51, and the limiting rod 51 is L-shaped. One end of the limiting rod 51 is adapted to the limiting hole 47;

[0027] The limiting rod 51 slides through the limiting frame 53. The limiting frame 53 is fixed on the valve body 1. A moving groove 54 is opened on the limiting frame 53. The moving groove 54 corresponds to the limiting rod 51, and the width of the moving groove 54 is the same as the diameter of the limiting rod 51;

[0028] A moving plate 55 is slidably installed in the moving groove 54. The moving plate 55 is adapted to the inside of the limiting frame 53. One side of the moving plate 55 is connected with a spring 56. The moving plate 55 is connected with the inner wall of the limiting frame 53 through the spring 56;

[0029] The limiting rod 51 penetrates through the middle of the moving plate 55. The limiting rod 51 is rotatably connected with the moving plate 55. A limiting ring 52 is fixedly installed on the limiting rod 51. The limiting ring 52 is located on the side of the moving plate 55 close to the spring 56.

[0030] Specifically, under normal circumstances, the spring 56 is in a natural stretched state. One end of the limiting rod 51 is inserted into the limiting hole 47, and the limiting rod 51 is used to limit the rotating frame 41 to prevent the rotating frame 41 from rotating unexpectedly due to various vibrations, bumps or accidental collisions. When it is necessary to use the handle 43 to control the rotation of the rotating frame 41, the operator pulls the limiting rod 51 through the bent part of the L-shaped limiting rod 51. During this process, the limiting rod 51 drives the limiting ring 52 to move, and pushes the moving plate 55 to slide along the moving groove 54. Through the connection between the moving plate 55 and the spring 56, the movement of the moving plate 55 causes the spring 56 to undergo an extended deformation. When the bent end of the limiting rod 51 moves to one side of the limiting frame 53, the operator rotates the limiting rod 51 so that its bent end fits against the outside of the limiting frame 53, causing the limiting rod 51 to be blocked by the limiting frame 53, preventing the limiting rod 51 from re-entering the limiting hole 47 under the pull of the spring 56 and affecting the rotation of the rotating frame 41;

[0031] After the rotation frame 41 finishes rotating, the operator rotates the limit rod 51 in the reverse direction so that the bent end of the limit rod 51 corresponds to the moving groove 54. Then, the limit rod 51 is pulled by the spring 56 and enters the corresponding limit hole 47, realizing the limitation of the rotation frame 41.

[0032] Working principle: Under normal conditions of the device, the spring 56 is in a natural stretched state. One end of the limit rod 51 is inserted into the limit hole 47 of the rotation frame 41 to limit the rotation frame 41. When it is necessary to adjust the lengths of the extension parts 3 at both ends of the valve body 1, the operator pulls the limit rod 51 through the bent part of the L-shaped limit rod 51. When the bent end of the limit rod 51 moves to one side of the limit frame 53, the operator rotates the limit rod 51. While the limit rod 51 is restricted by the limit frame 53, one end of the limit rod 51 disengages from the limit hole 47, facilitating the operator to overcome the magnetic forces of the first magnet 44 and the second magnet 46.

[0033] Pull the handle 43 up from the surface of the rotation frame 41. The operator holds the semi-circular handle 43 and controls the rotation of the rotation frame 41 through the handle 43. The rotation of the rotation frame 41 drives the screw rod 33 to rotate. Through the screw connection between the screw rod 33 and the connection block 32, the connection block 32 enters the corresponding connection hole 31 under the rotation of the screw rod 33. By corresponding the connection block 32 with different connection holes 31, the adjustment of the length of the extension part 3 is realized. After the length of the extension part 3 is adjusted, the operator rotates the limit rod 51 in the reverse direction so that the limit rod 51 corresponds to the moving groove 54 and moves along the moving groove 54 under the pull of the spring 56. Then, one end of the limit rod 51 can be promoted to enter the corresponding limit hole 47, realizing the limitation of the rotation frame 41.

[0034] The above shows and describes the basic principles, main features and advantages of the present utility model. For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic features of the present utility model.
