[0001] This utility model belongs to the field of marine ball valve technology, specifically a stainless steel ball valve for ships. Background Technology

[0002] As one of the most basic components in a pipeline system used to control fluid pressure, flow rate, and flow direction, ship valves play a crucial role. Failure of valves can lead to catastrophic accidents. To ensure stable system operation, more stringent requirements are placed on the reliability of ship valves during long-term operation.

[0003] The utility model patent with application number 202222709140.9 discloses a stainless steel flange ball valve, which includes a first valve body and a second valve body. Both ends of the first valve body and the second valve body are connected to a flange and a second flange. The connection between the first valve body, the second valve body and other pipelines requires connection and fixation through the flange and by means of threaded bolts, which greatly increases the number of connecting bolts, increases the complexity of the connection, and reduces the efficiency of disassembly and assembly. More importantly, special tools are required to tighten the bolts, which is inconvenient. Moreover, the use of tools is extremely inconvenient when the operating space is limited. Therefore, it is necessary to develop a stainless steel ball valve for ships to solve the shortcomings of the existing technology. Utility Model Content

[0004] To address the problems mentioned in the background section, this utility model provides a stainless steel ball valve for ships, which has the advantages of high connection efficiency and easy operation.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a stainless steel ball valve for ships, comprising a valve body, wherein a valve core is disposed inside the valve body, and a connecting flange is connected to both ends of the valve body, wherein the proximal ends of the two connecting flanges are respectively connected to the left and right ends of the valve core;

[0006] The connecting flange includes a flange plate disposed at the end of the valve body. A connecting pipe is fixedly connected to the side of the flange plate near the valve body. The other end of the connecting pipe is fixedly connected to the valve body. A sealing ring is fixedly connected to the other side of the flange plate. Several connecting parts located outside the connecting pipe and evenly distributed are movably sleeved inside the flange plate. A linkage ring is movably sleeved outside the connecting pipe. One end of the linkage ring is engaged with the end of several connecting parts. The other end of the linkage ring is rotatably sleeved on the outer surface of the connecting pipe through a bearing. An adapter groove is opened on the outer surface of the linkage ring. An operating element is movably connected inside the adapter groove.

[0007] Preferably, the connector includes a connecting rod passing through the inside of the flange. The end of the connecting rod away from the linkage ring passes through the flange and is provided with a connecting thread. The end of the connecting rod near the linkage ring passes through the flange and extends to the inner side of the linkage ring and is fixedly connected to an anti-detachment drive shaft. The outer surface of the anti-detachment drive shaft is engaged with the inner wall of the linkage ring.

[0008] Preferably, the operating component includes an operating wrench movably installed inside the adapter groove, the inner diameter of the operating wrench being adapted to the diameter of the inner wall of the adapter groove, and the diameter of the outer surface of the operating wrench being smaller than the outer circumferential diameter of the linkage ring.

[0009] Preferably, the lower end of the operating wrench is provided with a sliding groove, and a limiting shaft passes through the inside of the sliding groove. The two ends of the limiting shaft pass through the sliding groove and are fixedly connected to the inner wall of the adapter groove. The axis of the limiting shaft is parallel to the axis of the linkage ring.

[0010] Preferably, an anti-slip limiting sleeve is fixedly sleeved at the bottom of the inner cavity of the groove. The cross-section of the anti-slip limiting sleeve is "U" shaped. The inner diameter of the anti-slip limiting sleeve is adapted to the outer diameter of the limiting shaft. The inner wall of the anti-slip limiting sleeve and the outer surface of the limiting shaft are both rough.

[0011] Preferably, the slide groove is a circular arc, the center of the slide groove coincides with the center of the operating wrench, and the lower end of the operating wrench has a plurality of slots located on both sides of the slide groove and evenly distributed, the slots being interconnected with the slide groove; the inner diameter of the slots is larger than the outer diameter of the limiting shaft.

[0012] Preferably, the inner wall of the slot is rough. When the limiting shaft is inserted into the slot on one side by the sliding groove, the upper end of the operating wrench is moved so that the corresponding side of its lower end fits against the other side of the outer surface of the adapter groove, and the adapter groove is rotated.

[0027] 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.

[0028] like Figures 1 to 8 As shown, this utility model provides a stainless steel ball valve for ships, including a valve body 1, a valve core 3 is provided inside the valve body 1, and a connecting flange 2 is connected to both ends of the valve body 1. The proximal ends of the two connecting flanges 2 are respectively connected to the left and right ends of the valve core 3.

[0029] The connecting flange 2 includes a flange 21 disposed at the end of the valve body 1. A connecting pipe 23 is fixedly connected to the side of the flange 21 near the valve body 1, and the other end of the connecting pipe 23 is fixedly connected to the valve body 1. A sealing ring 27 is fixedly connected to the other side of the flange 21. Several connecting pieces 22 located outside the connecting pipe 23 and evenly distributed are movably sleeved inside the flange 21. A linkage ring 24 is movably sleeved outside the connecting pipe 23. One end of the linkage ring 24 is engaged with the end of the connecting pieces 22, and the other end of the linkage ring 24 is rotatably sleeved with a bearing. The outer surface of the connecting pipe 23 and the outer surface of the linkage ring 24 are provided with an adapter groove 25, and the adapter groove 25 is movably connected to the inside of the adapter groove 25. Due to the setting of the adapter 26, with the cooperation of the linkage ring 24 and the adapter groove 25, the operator can drive several connecting parts 22 to rotate synchronously through the adapter 26. Thus, under the restriction of the flange 21, several connecting parts 22 can be tightened onto the pipe to be connected at the same time, which greatly improves the screwing efficiency. Moreover, the extended adapter 26 can effectively reduce the resistance and further improve the tightening effect.

[0030] The connector 22 includes a connecting rod 221 that passes through the inside of the flange 21. The end of the connecting rod 221 away from the linkage ring 24 passes through the flange 21 and is provided with a connecting thread 223. The end of the connecting rod 221 near the linkage ring 24 passes through the flange 21 and extends to the inner side of the linkage ring 24 and is fixedly connected to an anti-detachment drive shaft 222. The outer surface of the anti-detachment drive shaft 222 is engaged with the inner wall of the linkage ring 24.

[0031] The control component 26 includes a control wrench 261 movably installed inside the adapter slot 25. The inner diameter of the control wrench 261 is matched with the diameter of the inner wall of the adapter slot 25, and the outer diameter of the control wrench 261 is smaller than the outer diameter of the linkage ring 24. Due to the design of the adapter slot 25, the control wrench 261 can be continuously connected to the adapter slot 25 with the cooperation of the limiting shaft 264, and the linkage ring 24 can be rotated through the adapter slot 25. Moreover, the control wrench 261 can be stored inside the adapter slot 25 with the cooperation of the anti-slip limiting sleeve 263, ensuring the neatness of the outer surface of the equipment for easy carrying and use.

[0032] The lower end of the operating wrench 261 is provided with a sliding groove 262, and a limiting shaft 264 passes through the inside of the sliding groove 262. Both ends of the limiting shaft 264 pass through the sliding groove 262 and are fixedly connected to the inner wall of the adapter groove 25. The axis of the limiting shaft 264 is parallel to the axis of the linkage ring 24. Due to the setting of the sliding groove 262, with the cooperation of the limiting shaft 264, it is convenient for the operator to swing the lower end of the operating wrench 261 to either side of the adapter groove 25. Then, under the restriction of the cooperation of the slot 265 and the limiting shaft 264, the linkage ring 24 can be rotated forward and backward by the abutting action between the two sides of the lower end of the operating wrench 261 and the inner wall of the adapter groove 25. Thus, under the restriction of the flange 21, it is possible to tighten or unscrew several connecting parts 22.

[0033] The bottom of the inner cavity of the slide groove 262 is fixedly fitted with an anti-slip limiting sleeve 263. The cross-section of the anti-slip limiting sleeve 263 is "U" shaped. The inner diameter of the anti-slip limiting sleeve 263 is matched with the outer diameter of the limiting shaft 264. The inner wall of the anti-slip limiting sleeve 263 and the outer surface of the limiting shaft 264 are both rough. Due to the setting of the anti-slip limiting sleeve 263, the position of the operating wrench 261 can be restricted with the cooperation of the limiting shaft 264, thereby ensuring that the operating wrench 261 can be firmly restricted in the fitting groove 25 for easy storage and to improve the carrying and use effect.

[0034] The slide groove 262 is a circular arc, and the center of the slide groove 262 coincides with the center of the operating wrench 261. The lower end of the operating wrench 261 has several slots 265 evenly distributed on both sides of the slide groove 262, and the slots 265 are interconnected with the slide groove 262. The inner diameter of the slots 265 is larger than the outer diameter of the limiting shaft 264. Due to the setting of the slots 265, when the upper end of the operating wrench 261 is turned, the lower end of the operating wrench 261 can fit against the corresponding side of the adapter groove 25 with the cooperation of the slide groove 262 and the limiting shaft 264, thereby driving the linkage ring 24 to rotate.

[0035] The inner wall of the slot 265 is rough. When the limiting shaft 264 is inserted into the inside of any slot 265 on one side by the slide groove 262, the upper end of the operating wrench 261 is moved so that the corresponding side of its lower end is attached to the other side of the outer surface of the adapter groove 25, and the adapter groove 25 is rotated.

[0036] Among them, the top of the valve body 1 is integrally formed with a shaft seal sleeve 4, the valve stem is sealed inside the shaft seal sleeve 4, the lower end of the valve stem extends into the interior of the valve body 1 and is fixedly connected to the top of the valve core 3, and the upper end of the valve stem passes through the shaft seal sleeve 4 and is fixedly connected to the valve stem 5.

[0037] Working principle and usage process of this utility model:

[0038] First, unfold the operating wrench 261 from inside the adapter slot 25, causing the limiting shaft 264 to disengage from the anti-slip limiting sleeve 263 and slide into the slide groove 262. Then, adjust the position of the lower end of the operating wrench 261 according to the connection or disassembly requirements, so that the lower end of the operating wrench 261 fits against either the left or right side of the inner wall of the adapter slot 25 with the cooperation of the slide groove 262 and the limiting shaft 264. The specific selection depends on the direction of force application. Then, make the limiting shaft 264 engage in the slot 265 on the corresponding force-applying side. Finally, turn the upper end of the operating wrench 261. Under the action of the fit between its lower end and the inner wall of the adapter groove 25, and the fit and support of the inner walls of the limiting shaft 264 and the slot 265, the linkage ring 24 rotates relative to the flange 21 under the action of the bearing, thereby driving several anti-detachment transmission shafts 222 to rotate synchronously, and then driving the connecting thread 223 to rotate synchronously through the connecting rod 221, so that several connecting threads 223 are tightened to the front end of the pipe to be connected at the same time, thereby quickly completing the connection. Then, the operation is reversed to flip the operating wrench 261 into the adapter groove 25 for storage.
