Description

Technical Field

[0001] The utility model relates to the technical field of valves, and in particular to a multiple sealing valve. Background Art

[0002] A valve is a pipe fitting used to open and close pipes, control flow direction, regulate and control the medium being transported, and is a device that allows the medium in pipes and equipment to flow or stop and control its flow rate. In the prior art, in order to improve the sealing effect of the valve, some valves are equipped with multiple valve plate seals to improve the sealing of the valve and avoid leakage of the medium in the valve. The valve plate is rotated by controlling the valve handle to adjust the flow rate of the medium.

[0003] The existing patent application number CN202222656946.6 discloses a multi-seal valve including: a multi-seal valve body, an adjusting shell, an anti-drop plate, an adjusting rod, an adjusting groove, an adjusting column, a connecting rod, a limit column, a slide groove, and a limit block; the beneficial effects are: pulling the adjusting rod upward so that its end exceeds the height of the valve handle, and then rotating the connecting rod to move the limit column to the outside of the adjusting rod, aligning the limit column with the fixing hole, loosening the connecting rod spring to drive the adjusting rod to move downward, so that the limit column is inserted into the fixing hole to position the valve handle, avoiding the situation where external objects touch the valve handle and cause the valve handle to rotate when the multi-seal valve body is not in use, tightening the bolt so that the adjusting column cannot rotate, thereby effectively improving the stability of the limit column inserted into the fixing hole.

[0004] The above scheme has the following shortcomings during implementation: when the valve handle needs to be rotated, the bolt needs to be unscrewed first before the adjusting column can be removed from the top of the valve handle. As a result, the bolt is difficult to be easily removed without tools, which causes certain inconveniences to the opening or closing of the valve. At the same time, the bolt is easy to be lost during the removal process, thereby affecting the subsequent fixation of the valve handle. Therefore, a multi-sealing valve is needed to solve the above problems. Utility Model Content

[0005] The utility model aims to provide a multi-sealing valve, which solves the problem in the prior art that when the valve handle needs to be rotated, the bolts need to be unscrewed first before the adjusting column can be removed from the top of the valve handle, resulting in that the bolts are difficult to be easily removed without tools, thereby causing certain inconveniences in opening or closing the valve, and the bolts are also prone to being lost during the removal process, thereby affecting the subsequent fixation of the valve handle.

[0010] As a preferred embodiment of the above technical solution, a plug hole is provided at the bottom end of the valve handle, the plug hole is adapted to fit the plug rod, and a screw hole is provided at the side end of the valve handle.

[0011] As a preferred embodiment of the above technical solution, the fixing mechanism includes a side plate, which is fixedly connected to the side end of the insertion rod, and the side end of the side plate is provided with a T-shaped slide groove, and the inside of the slide groove is slidably connected with a T-shaped slider, the side end of the slider is fixedly connected with a fixing plate, the side end of the fixing plate is fixedly connected with an annular plate, a bearing is installed on the inner side of the annular plate, a panel is installed on the inner side of the bearing, the side end of the panel is fixedly connected with a screw, and the side end of the panel is fixedly connected with a swivel.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The utility model is provided with the fixing mechanism and the limiting mechanism. When the valve handle needs to be rotated, the screw rod is moved out of the screw hole by rotating the rotating ring. At this time, the slider slides to the outermost end of the sliding groove. At this time, the screw rod and the side end of the valve handle are no longer in contact. At this time, by pulling the pull head downward, the extension plate can drive the circular plate and the plug rod to move downward until the plug rod is separated from the insertion hole, and the valve handle can realize normal rotation. At this time, when the extension plate moves downward to the lowest end of the vertical groove, the extension plate can be rotated to make the extension plate located in the horizontal groove. Then, the horizontal groove has a limiting block on the extension plate. After releasing the pull head, the plug rod can always be located at the bottom end of the valve handle, thereby not affecting the rotation of the valve handle. Therefore, the device is provided with the fixing mechanism. The screw rod can be easily disassembled through the rotating ring without tools, thereby making it easier and faster to open or close the valve. At the same time, the screw rod will not be lost because it is always limited in the sliding groove by the slider during the removal process, thereby avoiding affecting the subsequent fixing of the valve handle.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0021] like Figure 1-4As shown, the utility model provides a technical solution: a multi-sealed valve, comprising a multi-sealed valve body 1, a valve handle 101 is installed at the top of the multi-sealed valve body 1, a plug hole 102 is provided at the bottom end of the valve handle 101, a screw hole 103 is provided at the side end of the valve handle 101, a limiting mechanism for limiting the rotation of the valve handle 101 is provided at the top of the multi-sealed valve body 1, and a fixing mechanism for fixing the limiting mechanism is provided at the side end of the limiting mechanism. Through the coordinated arrangement of the limiting mechanism and the fixing mechanism, dual limiting and fixing of the valve handle 101 are achieved, thereby improving the fixing effect of the valve handle 101. At the same time, through the arrangement of the fixing mechanism, the fixing mechanism can be easily disassembled without tools, thereby making the opening or closing of the valve easier and quicker, and the valve will not be lost, thereby avoiding affecting the subsequent fixation of the valve handle 101.

[0022] As an implementation method in this embodiment, Figure 1 , Figure 2 and Figure 3 As shown, the limiting mechanism includes a hollow rod 2, which is fixedly connected to the top of the multi-seal valve body 1, and a spring 203 is fixedly connected to the bottom end of the hollow rod 2. A circular plate 204 is placed on the top of the spring 203 inside the hollow rod 2, and a plug rod 205 is fixedly connected to the top of the circular plate 204. The plug hole 102 is adapted to the plug rod 205. The fixing mechanism is arranged at the side end of the plug rod 205, and a vertical groove 201 is provided at the side end of the hollow rod 2. The bottom side end of the vertical groove 201 is provided with a There is a horizontal groove 202, and the side end of the circular plate 204 is fixedly connected with an extension plate 206, and the side end of the extension plate 206 is fixedly connected with a pull head 207. The extension plate 206 is located in the vertical groove 201. During implementation, the spring 203 always presses the circular plate 204 and the insertion rod 205 in the hollow rod 2, so that the insertion rod 205 is always limited in the insertion hole 102 at the bottom end of the valve handle 101, thereby realizing the initial limit fixation of the valve handle 101, so that the valve handle 101 cannot be touched at will and rotated.

[0023] Furthermore, when the valve handle 101 needs to be rotated, by pulling the pull head 207 downward, the extension plate 206 can drive the circular plate 204 and the plug rod 205 to move downward until the plug rod 205 is out of the insertion hole 102, and the valve handle 101 can achieve normal rotation. At this time, when the extension plate 206 moves downward to the lowest end of the vertical groove 201, the extension plate 206 can be rotated to make the extension plate 206 located in the horizontal groove 202. Then, with the horizontal groove 202 limiting the extension plate 206, after releasing the pull head 207, the plug rod 205 can always be located at the bottom end of the valve handle 101, thereby not affecting the rotation of the valve handle 101.

[0024] As an implementation method in this embodiment, Figure 2 and Figure 4As shown, the fixing mechanism includes a side plate 3, which is fixedly connected to the side end of the plug rod 205, and a T-shaped slide groove 301 is provided at the side end of the side plate 3. A T-shaped slider 302 is slidably connected inside the slide groove 301, and a fixing plate 303 is fixedly connected to the side end of the slider 302, and an annular plate 304 is fixedly connected to the side end of the fixing plate 303. A bearing 305 is installed on the inner side of the annular plate 304, and a panel 306 is installed on the inner side of the bearing 305. A screw 307 is fixedly connected to the side end of the panel 306, and the screw 307 is threadedly connected in the screw hole 103. A swivel 308 is fixedly connected to the side end of the panel 306. In implementation, since the screw 307 is located at the side end of the valve handle 101 facing the valve handle 101, the screw 307 is fixedly connected to the side end of the valve handle 101. The position of the screw hole 103, at this time, by rotating the rotating ring 308, since the bearing 305 is set on the inner side of the annular plate 304, the panel 306 and the screw 307 can be easily rotated, and the screw 307 is pushed to move in the direction of the screw hole 103, and after the screw 307 contacts the screw hole 103, the rotating ring 308 is rotated, and the screw 307 can be gradually threaded into the screw hole 103. At this time, the slider 302 moves in the slide groove 301, so that the plug rod 205 can be fixed in the socket 102 and will not move downward at will, so that it will not easily detach from the socket 102, thereby realizing double limiting and fixation of the valve handle 101, thereby improving the fixing effect of the valve handle 101.

[0025] Furthermore, the device has a fixing mechanism so that the screw 307 can be easily disassembled through the swivel 308 without the need for tools, thereby making the opening or closing of the valve easier and quicker. At the same time, the screw 307 is always limited in the slide groove 301 by the slider 302 during the removal process, so it will not be lost, thereby avoiding affecting the subsequent fixation of the valve handle 101.

[0026] Working principle: The spring 203 always presses against the circular plate 204 and the plug rod 205 in the hollow rod 2, so that the plug rod 205 is always limited in the plug hole 102 at the bottom end of the valve handle 101, thereby realizing the initial limit fixation of the valve handle 101, so that the valve handle 101 cannot be randomly touched and rotated. Then, since the screw rod 307 is located at the side end of the valve handle 101 facing the screw hole 103, after rotating the swivel 308, since the bearing 305 is set on the inner side of the annular plate 304, it is convenient for the panel 306 and the screw rod 307 to rotate. 07 is rotated, and the screw rod 307 is pushed to move in the direction of the screw hole 103. After the screw rod 307 contacts the screw hole 103, the swivel ring 308 is rotated, and the screw rod 307 can be gradually threaded into the screw hole 103. At this time, the slider 302 moves in the slide groove 301, so that the plug rod 205 can be fixed in the socket 102 and will not move downward at will, so that it will not easily separate from the socket 102, thereby realizing double limiting and fixing of the valve handle 101, thereby improving the fixing effect of the valve handle 101.

[0027] When the valve handle 101 needs to be rotated, the screw 307 is moved out of the screw hole 103 by rotating the rotating ring 308. At this time, the slider 302 slides to the outermost end of the slide groove 301. At this time, the screw 307 is no longer in contact with the side end of the valve handle 101. At this time, by pulling the pull head 207 downward, the extension plate 206 can drive the circular plate 204 and the plug rod 205 to move downward until the plug rod 205 is out of the insertion hole 102. The valve handle 101 can achieve normal rotation. At this time, when the extension plate 206 moves downward to the lowest end of the vertical groove 201, the extension plate 206 can be rotated to make the extension plate 206 located in the horizontal groove The screw rod 307 is fixed in the sliding groove 301 by the slider 302 during the removal process, so that the screw rod 307 will not be lost, thereby avoiding affecting the subsequent fixation of the valve handle 101.

[0028] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
