Description

Technical Field

[0001] This utility model relates to the field of flange gate valve devices, and in particular to an adjustable high-precision flange gate valve. Background Technology

[0002] In modern industrial production and civil building systems for water supply, drainage, heating, and gas supply, flanged gate valves play a crucial role as key equipment for controlling the flow of media in pipelines. In the industrial sector, pipeline transportation systems in industries such as chemical, power, and petroleum require precise regulation of media flow to ensure the stability and safety of production processes. In civil buildings, from residential water supply systems to commercial building air conditioning circulation systems, the effective control of water or gas flow by flanged gate valves is indispensable. Therefore, the performance of flanged gate valves directly affects the operating efficiency and reliability of various systems.

[0003] Currently, traditional flange gate valves present several problems in practical applications. Regarding regulation accuracy, many traditional flange gate valves employ simple on / off structures or crude regulation methods, making it difficult to achieve precise control of media flow rate. For example, in some chemical production processes with extremely high flow control requirements, traditional flange gate valves cannot meet the process's demand for precise flow, leading to unstable product quality or low production efficiency. Their regulation process often relies on the operator's experience and judgment, lacking a precise regulation mechanism and unable to adapt to complex and changing operating conditions. In terms of connection stability, traditional flange gate valves have relatively simple connection methods, typically relying on simple fasteners such as bolts for fixation. Under long-term exposure to factors such as media pressure, temperature changes, and pipeline vibration, the connections are prone to loosening. Once the connections loosen, it not only leads to media leakage, causing resource waste and environmental pollution, but may also trigger safety accidents, seriously threatening personnel safety and the normal operation of production facilities. Furthermore, the maintenance and replacement of parts with traditional flange gate valves are cumbersome, consuming significant time and labor costs.

[0004] In response to this technical problem, this application proposes an adjustable high-precision flange gate valve. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an adjustable high-precision flange gate valve. This improves the flexibility of flange gate valves in use, enabling them to function efficiently in both industrial pipelines and civil facilities. It ensures the safe and reliable operation of pipeline systems, reduces the risk of failures caused by unstable connections, and extends the service life of flange gate valves.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] An adjustable high-precision flange gate valve includes a flange gate valve body. A first preset connecting plate is fixedly connected to the top of the flange gate valve body. A reserved snap-fit ​​groove is opened on the top side of the first preset connecting plate. A fixed adjusting plate is provided on the top side of the flange gate valve body. A second preset connecting plate is fixedly connected to the bottom of the fixed adjusting plate. A fixed sealing plate is fixedly connected to the bottom side of the second preset connecting plate. The first preset connecting plate and the second preset connecting plate are connected by a fixing component. An adjusting valve plate is connected to the top side of the fixed adjusting plate by an adjusting component. Flanges are fixedly connected to both the left and right ends of the flange gate valve body.

[0008] Furthermore, the fixing component includes a fixing screw that is threaded to both the left and right ends of the second preset connecting plate, a preset abutment rod that is slidably connected to the bottom end of the fixing screw, and a limit spring is provided inside the first preset connecting plate.

[0009] Furthermore, one end of the limiting spring is connected to the inside of the fixing screw, and the other end is connected to the top side of the preset abutment rod.

[0010] Furthermore, the adjustment assembly includes an adjustment knob rotatably connected to the top side of the fixed adjustment plate, an adjustment screw rod is internally threaded onto the adjustment knob, a fixed mounting block is fixedly connected to the top of the adjustment valve plate, and a preset limit cap is fixedly connected to the top side of the adjustment screw rod.

[0011] Furthermore, the bottom end of the adjusting screw is fixedly connected inside the fixed mounting block.

[0012] Furthermore, two holes are provided at both ends of the first preset connecting plate, and the preset abutment...

[0013] The outer wall of the connecting rod is slidably connected to the inner wall of the hole.

[0014] Furthermore, the outer wall of the fixing screw penetrates the interior of the second preset connecting plate.

[0015] Furthermore, the diameter of the regulating valve plate is the same as the inner diameter of the flange gate valve body. This invention has the following beneficial effects:

[0016] 1. In this utility model, the operator only needs to rotate the adjusting knob to move the adjusting screw rod vertically via the threaded connection, precisely controlling the fit between the regulating valve plate and the water pipe inside the flange gate valve body, thereby conveniently controlling the flow rate. The forward and reverse rotation of the adjusting knob allows for flexible adjustment of the regulating valve plate position, meeting diverse needs for water flow velocity in different scenarios, greatly improving the flexibility of the flange gate valve. It can play an efficient role in both industrial pipelines and civil facilities.

[0017] 2. In this utility model, the flange gate valve body and the fixed adjusting plate are connected by a fixing screw. The preset abutment rod inside the fixing screw, under the reaction force of the limiting spring, makes the connection between the two more tight. This design effectively enhances the stability of the overall structure, avoids loosening and leakage under water flow impact, ensures the safe and reliable operation of the pipeline system, reduces the risk of failure caused by unstable connection, and extends the service life of the flange gate valve.

[0024] 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.

[0025] Refer to Figure 1 and Figure 2This utility model provides an embodiment of an adjustable high-precision flange gate valve, comprising a flange gate valve body 1. A first preset connecting plate 3 is fixedly connected to the top of the flange gate valve body 1. A reserved snap-fit ​​groove 10 is provided on the top side of the first preset connecting plate 3. A fixed adjusting plate 2 is provided on the top side of the flange gate valve body 1. A second preset connecting plate 4 is fixedly connected to the bottom end of the fixed adjusting plate 2. A fixed sealing plate 11 is fixedly connected to the bottom side of the second preset connecting plate 4. The first preset connecting plate 3 and the second preset connecting plate 4 are connected by a fixing screw 9. An adjusting valve plate 13 is connected to the top side of the fixed adjusting plate 2 by an adjusting screw rod 7. Flanges 5 are fixedly connected to both ends of the flange gate valve body 1. Two holes 16 are provided at both ends of the first preset connecting plate 3. The outer wall of a preset abutment rod 14 is slidably connected to the inner wall of the hole 16. The outer wall of the fixing screw 9 penetrates the interior of the second preset connecting plate 4. The diameter of the adjusting valve plate 13 is the same as the inner diameter of the flange gate valve body 1.

[0026] Specifically, when operating an adjustable high-precision flange gate valve, the operation is simple and precise when the operator needs to adjust the flange gate valve body 1 to control the water flow rate. First, an adjusting knob 6 is installed on the top side of the fixed adjusting plate 2. By rotating this adjusting knob 6, and utilizing its threaded connection with the adjusting screw rod 7, the operator can move the adjusting screw rod 7 in the vertical direction simply by changing the forward and reverse direction of the adjusting knob 6.

[0027] Referring to Figure 3, an adjustment knob 6 is rotatably connected to the top side of the fixed adjustment plate 2. The adjustment knob 6 has an internal screw...

[0028] The regulating valve plate 13 is connected to an adjusting screw rod 7, and a fixed mounting block 12 is fixedly connected to the top of the regulating valve plate 13. A preset limit cap 8 is fixedly connected to the top side of the adjusting screw rod 7. The bottom end of the adjusting screw rod 7 is fixedly connected to the inside of the fixed mounting block 12.

[0029] Specifically, under the action of the threaded connection, the adjusting screw rod 7 can move smoothly up and down inside the fixed adjusting plate 2. When the adjusting screw rod 7 rises or falls to a certain extent, the bottom side of the preset limit cap 8 contacts the top side of the adjusting knob 6, and the vertical movement of the adjusting screw rod 7 is restricted. At this time, the adjusting valve plate 13 on the bottom side of the adjusting screw rod 7 is exactly in contact with the water pipe inside the flange gate valve body 1. In this way, the operator can conveniently and accurately control the water flow rate.

[0030] Reference Figure 4The second preset connecting plate 4 has a fixing screw 9 threadedly connected to both ends. The bottom of the fixing screw 9 is slidably connected to a preset abutment rod 14. The first preset connecting plate 3 has a limit spring 15 installed inside. One end of the limit spring 15 is connected to the inside of the fixing screw 9, and the other end is connected to the top side of the preset abutment rod 14.

[0031] Specifically, the flange gate valve body 1 and the fixed adjusting plate 2 are connected by a fixing screw 9. During installation, the operator fixes the fixing screw 9 at the connection point between the flange gate valve body 1 and the fixed adjusting plate 2. A pre-set abutment rod 14 is provided at the bottom of the fixing screw 9. After the fixing screw 9 is installed in place, the pre-set abutment rod 14 will contact the bottom side of the hole 16. Simultaneously, a limit spring 15 is also provided inside the fixing screw 9. The elastic potential energy generated by the deformation of the limit spring 15 will produce a reaction force on the pre-set abutment rod 14 and the fixing screw 9. Under the action of this reaction force, the connection between the flange gate valve body 1 and the fixed adjusting plate 2 is tighter, greatly enhancing the structural stability of the entire flange gate valve and ensuring its stable operation during use.

[0032] Working principle: When the operator needs to adjust the flange gate valve body 1, he / she can achieve this by rotating the adjusting knob 6 installed on the top side of the fixed adjusting plate 2, thereby changing the forward and reverse direction of the adjusting knob 6.

[0033] The adjusting screw rod 7, which is threadedly connected to the adjusting knob 6, is moved vertically. Under the action of the threaded connection, the adjusting screw rod 7 can move up and down inside the fixed adjusting plate 2. When the bottom side of the preset limit cap 8 contacts the top side of the adjusting knob 6, the vertical movement of the adjusting screw rod 7 is limited. At this time, the adjusting valve plate 13 on the bottom side of the adjusting screw rod 7 is completely in contact with the water pipe inside the flange gate valve body 1, so as to realize convenient control of the flow rate.

[0034] The flange gate valve body 1 and the fixed adjusting plate 2 are connected by a fixing screw 9. The operator fixes the fixing screw 9 at the connection between the flange gate valve body 1 and the fixed adjusting plate 2. At this time, the preset abutment rod 14 at the bottom inside the fixing screw 9 will contact the bottom inside the hole 16. At the same time, the elastic potential energy generated by the deformation of the limit spring 15 will generate a reaction force on the preset abutment rod 14 and the fixing screw 9, thereby making the connection between the flange gate valve body 1 and the fixed adjusting plate 2 tighter and enhancing the structural stability.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
