Description

Technical Field

[0001] This utility model relates to the field of drain valves, and more specifically, to a drain valve designed to prevent misoperation. Background Technology

[0002] A drain valve is a special valve used to discharge liquids, gases or solid impurities accumulated in pipes or containers. It has the functions of draining sewage and slag, venting gas and relieving pressure, and emptying media. It can remove scale and sludge from boilers and pipes (such as regular sewage discharge of high-pressure boilers), remove residual gas in pipelines to prevent air cushion formation, maintain stable system pressure, and quickly empty pipeline media in emergencies or during maintenance.

[0003] In the current drain valve, the internal ball valve core is connected to the valve stem for rotation adjustment during use. However, during operation, the operator may accidentally touch the valve stem, causing it to rotate unnecessarily. This affects the flow of the pipeline and reduces the practicality of the device. Utility Model Content

[0004] One objective of this invention is to provide a new technical solution for a drain valve that prevents misoperation.

[0005] According to a first aspect of the present invention, a misoperation prevention sewage valve is provided, comprising: a valve body, wherein the valve body is provided with a misoperation prevention mechanism and an assembly mechanism, the misoperation prevention mechanism includes a valve seat, the valve seat is fixedly disposed on the valve body, a ball valve core inside the valve seat is connected to a ball valve core rotating rod, a connecting rod is assembled at the upper end of the ball valve core rotating rod, a valve wheel is fixedly connected at the upper end of the connecting rod, a fixing column is fixedly connected at the upper end of the valve seat, a limit column is slidably connected inside the fixing column through an adjusting component, the limit column is inserted into a limit hole, and the limit hole is opened inside the valve wheel;

[0006] The adjustment assembly includes a fixing rod, which is fixedly connected to the inner wall of a fixing column and inserted into a limiting column. The limiting column can slide on the surface of the fixing rod. A spring is wound around the surface of the fixing rod, with one end of the spring connected to the bottom end of the limiting column and the other end of the spring connected to the inner wall of the fixing column.

[0007] Preferably, a limiting block is fixedly connected to the outer wall of the ball valve core rotating rod, the limiting block is locked inside the limiting groove, an annular groove is provided below the limiting groove, and the annular groove opened inside the valve seat allows the limiting block to rotate.

[0008] Preferably, a slider is fixedly connected to the side wall of the fixed rod, and the slider is slidably disposed inside the slide groove, which is opened inside the fixed column.

[0009] Preferably, there are two sets of fixed posts and limiting posts, and the angle between the two sets of fixed posts and the center point of the valve wheel is 90 degrees.

[0010] Preferably, the assembled mechanism includes a connecting part, which is fixedly connected to the bottom end of the connecting rod. The ball valve core rotating rod has a connecting groove inside, and the connecting part is threaded into the connecting groove.

[0011] Preferably, an anti-slip seat is fixedly connected to the outer wall of the ball valve core rod, and the surface of the anti-slip seat is provided with anti-slip texture.

[0012] 1. This utility model utilizes the cooperation of a valve seat, ball valve core rotating rod, connecting rod, valve wheel, fixed column, limit column, limit hole, fixed rod, spring, limit block, and limit groove. To prevent accidental opening and closing of the ball valve core due to valve wheel misoperation, when not in operation, the limit column can be pulled downwards, causing it to compress the spring wound on the surface of the fixed rod and disengage from the limit hole. Rotating the valve wheel completes the adjustment of the ball valve core. At this time, the spring is in a compressed, stored state. Releasing the limit column allows the spring's elasticity to automatically drive the limit column into the limit hole, thus limiting the position of the valve wheel and preventing accidental opening and closing by personnel. The rotation of the valve wheel causes the ball valve core to open and close automatically. When the ball valve core needs adjustment, the valve wheel needs to be pressed, causing the connecting rod and the ball valve core rotating rod to move downwards synchronously, causing the limit block to press down synchronously and enter the annular groove inside the valve body. At this time, the valve wheel can be rotated to drive the ball valve core to rotate and adjust, avoiding accidental operation of the drain valve by personnel. This anti-misoperation drain valve can use the dual operation of pressing and rotating to adjust the opening and closing of the ball valve core, avoiding accidental operation. In addition, the position of the valve wheel can be limited by the limit pin, providing dual anti-misoperation control, which improves the practicality and safety of the device.

[0013] 2. This utility model, through the cooperation of the connecting part, connecting groove, and anti-slip seat, avoids the need for replacement due to damage to the valve wheel or connecting rod. It changes the traditional valve stem to a two-end split structure, consisting of a ball valve core rotating rod and a connecting rod. The ball valve core rotating rod and the connecting rod are connected by threads through the connecting part and connecting groove, facilitating easy assembly and disassembly. The operator can hold the anti-slip seat, increasing the friction between the anti-slip seat and the hand to prevent slippage and control the ball valve core rotating rod from rotating. The connecting part and connecting groove can be easily assembled. This anti-misoperation sewage valve changes the traditional valve stem to a two-end split structure, facilitating replacement when the valve wheel is damaged, and improving the practicality and convenience of the device.

It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present invention.

[0022] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0023] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0024] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0025] like Figure 1-4 As shown, one embodiment of this utility model is provided:

[0026] A misoperation prevention drain valve is provided. The valve body 111 used in this application is a product that can be directly purchased on the market. Its principle and connection method are existing technologies known to those skilled in the art.

[0027] Includes: valve body 111, valve body 111 is provided with anti-misoperation mechanism 2 and assembly mechanism 3, anti-misoperation mechanism 2 includes valve seat 211, valve seat 211 is fixedly installed on valve body 111, ball valve core inside valve seat 211 is connected to ball valve core rotating rod 212, ball valve core rotating rod 212 is equipped with connecting rod 213 at the upper end, valve wheel 214 is fixedly connected to the upper end of connecting rod 213, fixed column 215 is fixedly connected to the upper end of valve seat 211, limit column 216 is slidably connected inside fixed column 215 through adjustment component, limit column 216 is inserted into limit hole 217, limit hole 217 is opened inside valve wheel 214;

[0028] The adjustment assembly includes a fixed rod 218, which is fixedly connected to the inner wall of the fixed post 215. The fixed rod 218 is inserted into the limiting post 216, which can slide on the surface of the fixed rod 218. A spring 219 is wound around the surface of the fixed rod 218. One end of the spring 219 is connected to the bottom end of the limiting post 216, and the other end of the spring 219 is connected to the inner wall of the fixed post 215.

[0029] When using this anti-misoperation drain valve, the rotation of the valve wheel 214 drives the ball valve core rod 212 to rotate synchronously, which can adjust the opening and closing of the ball valve core. To prevent accidental contact of the valve wheel 214 that could cause the ball valve core to open or close, when not in operation, the limit post 216 can be pulled downwards, causing the limit post 216 to press against the spring 219 wound on the surface of the fixing rod 218, and the limit post 216 to disengage from the limit hole 217. After rotating the valve wheel 214 to adjust the ball valve core, the spring 219 is in a compressed and stored state. Releasing the limit post 216 allows the elastic force of the spring 219 to automatically drive the limit post 216 to insert into the limit hole 217, which can limit the position of the valve wheel 214 and prevent accidental contact of the valve wheel 214 that could cause the ball valve core to open or close automatically.

[0030] A limit block 222 is fixedly connected to the outer wall of the ball valve core rotating rod 212. The limit block 222 is locked inside the limit groove 223. An annular groove is provided below the limit groove 223. The annular groove opened inside the valve seat 211 allows the limit block 222 to rotate.

[0031] When the ball valve core needs to be adjusted, the valve wheel 214 needs to be pressed to make the connecting rod 213 and the ball valve core rotating rod 212 move downward synchronously, so that the limit block 222 is pressed down synchronously and the limit block 222 enters the annular groove inside the valve body 111. At this time, the valve wheel 214 can be rotated to drive the ball valve core to rotate and adjust, so as to avoid personnel accidentally touching the drain valve.

[0032] A slider 220 is fixedly connected to the side wall of the fixed rod 218. The slider 220 is slidably disposed inside the slide groove 221, which is opened inside the fixed column 215.

[0033] When the fixed rod 218 moves, the slider 220 moves synchronously inside the slide groove 221, thereby limiting the movement of the fixed rod 218 and making its sliding more stable.

[0034] Two sets of fixed posts 215 and limiting posts 216 are provided, and the angle between the two sets of fixed posts 215 and limiting posts 216 and the center point of valve wheel 214 is 90 degrees.

[0035] The angle between the two sets of fixed posts 215 and limit posts 216 and the center point of valve wheel 214 is 90 degrees. When the valve wheel 214 is adjusted by 90 degrees to open and close the ball valve core, the two sets of fixed posts 215 and limit posts 216 can work together to limit the position of valve wheel 214, which is more convenient and has a better limiting effect.

[0036] The assembled mechanism 3 includes a connecting part 311, which is fixedly connected to the bottom end of the connecting rod 213. The ball valve core rotating rod 212 has a connecting groove 312 inside, and the connecting part 311 is threaded into the connecting groove 312.

[0037] When using this anti-misoperation drain valve, in order to avoid the need to replace the valve wheel 214 or connecting rod 213 due to damage, the traditional valve stem is changed to a split structure at both ends, which is assembled from the ball valve core rotating rod 212 and the connecting rod 213. The ball valve core rotating rod 212 and the connecting rod 213 are connected by a threaded connection part 311 and a connecting groove 312, which makes disassembly and assembly convenient.

[0038] An anti-slip seat 313 is fixedly connected to the outer wall of the ball valve core rod 212, and the surface of the anti-slip seat 313 is provided with anti-slip texture.

[0039] When it is necessary to assemble the connecting part 311 and the connecting groove 312, the operator can hold the anti-slip seat 313 to increase the friction between the anti-slip seat 313 and the hand, avoid slipping, and control the ball valve core rod 212 to prevent it from rotating, so as to facilitate the assembly of the connecting part 311 and the connecting groove 312.

[0040] Working principle:

[0041] When using this anti-misoperation drain valve, the rotation of the valve wheel 214 drives the ball valve core rotating rod 212 to rotate synchronously, which can adjust the opening and closing of the ball valve core. To prevent accidental contact of the valve wheel 214 that could cause the ball valve core to open or close, when not in operation, the limit pin 216 can be pulled downwards, causing the limit pin 216 to press against the spring 219 wound on the surface of the fixing rod 218, and the limit pin 216 to disengage from the limit hole 217. Rotating the valve wheel 214 completes the adjustment of the ball valve core. At this time, the spring 219 is in a compressed and stored state. Releasing the limit pin 216 allows the spring 219 to be used for adjustment. The elastic force of valve 19 automatically drives the limiting post 216 to insert into the limiting hole 217, which can limit the position of valve wheel 214 and prevent personnel from accidentally rotating valve wheel 214, causing the ball valve core to open and close automatically. When the ball valve core needs to be adjusted, valve wheel 214 needs to be pressed to make connecting rod 213 and ball valve core rotating rod 212 move downward synchronously, so that limiting block 222 is pressed down synchronously and enters the annular groove inside valve body 111. At this time, valve wheel 214 can be rotated to drive ball valve core to rotate for adjustment, preventing personnel from accidentally operating the discharge valve.

[0042] When using this anti-misoperation drain valve, to avoid damage to the valve wheel 214 or connecting rod 213 requiring replacement, the traditional valve stem is changed to a two-part split structure, consisting of a ball valve core rotating rod 212 and a connecting rod 213. The ball valve core rotating rod 212 and the connecting rod 213 are connected by a threaded connection part 311 and a connecting groove 312, making disassembly and assembly convenient. The operator can hold the anti-slip seat 313 to increase the friction between the anti-slip seat 313 and the hand, preventing slippage and controlling the ball valve core rotating rod 212 to prevent rotation. The connection part 311 and the connecting groove 312 can be easily assembled, thus completing the operation.
