Its core function is to achieve precise regulation of desuperheating water and pressure reduction to prevent damage through a multi-stage throttling structure.

[0003] The handwheel of some existing multi-stage throttling desuperheating water regulating valves does not have a limit structure. After adjustment, especially when the multi-stage throttling desuperheating water regulating valve is in a relatively complex operating environment, the handwheel is easily accidentally touched and rotated, causing unexpected adjustment of the multi-stage throttling desuperheating water regulating valve, affecting the stability of use, and the display screen is not easy to protect.

[0004] To address this, a multi-stage throttling desuperheating water regulating valve is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a multi-stage throttling desuperheating water regulating valve, which can solve the problems of existing multi-stage throttling desuperheating water regulating valves not having a limiting structure on the handwheel. After adjustment, especially when the multi-stage throttling desuperheating water regulating valve is in a relatively complex operating environment, the handwheel is easily accidentally touched and rotated, causing unexpected adjustment of the multi-stage throttling desuperheating water regulating valve, affecting the stability of use, and the display screen is not easy to protect.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a multi-stage throttling desuperheating water regulating valve, comprising a desuperheating water regulating valve body, a handwheel body, and a display screen body. Connecting clips are provided on both sides of the top of the desuperheating water regulating valve body, and a limit mechanism is provided on the top of the connecting clips. A protective mechanism is provided on the front side of the desuperheating water regulating valve body. The limiting mechanism includes a silicone pad, a limiting plate, a limiting post, and a fixing cylinder. The bottom of the silicone pad is fixedly connected to the top of the limiting plate, the bottom of the limiting plate is rotatably connected to the top of the limiting post, and the bottom of the limiting post extends into the interior of the fixing cylinder and is threadedly connected to the interior of the fixing cylinder.

[0007] Preferably, the protective mechanism includes two rotating columns, an iron guard plate, and a viewing window. The rotating columns are fixedly connected to the iron guard plate on the side closest to the iron guard plate. The viewing window is embedded inside the iron guard plate. Both the iron guard plate and the viewing window are located on the front side of the display screen body.

[0008] Preferably, each of the two connecting cards has a rotating hole on its front side on the opposite side, and the rotating column is rotatably connected inside the rotating hole.

[0009] Preferably, the surface of the rotating column is chamfered, and a pull ring is fixedly connected to the front side of the iron guard plate.

[0010] Preferably, magnetic blocks are fixedly connected to both sides of the front side of the desuperheating water regulating valve body, and the front side of the magnetic blocks is magnetically attracted to the rear side of the iron guard plate.

[0011] Preferably, the surface of the limiting post is fixedly connected with a screw post, and the number of screw posts is several and they are evenly distributed on the surface of the limiting post.

[0016] Compared with the prior art, the beneficial effects of this utility model are: 1. This application sets up a limiting mechanism, fixes the fixed cylinder with a support block, and connects the limiting post to the fixed cylinder with a thread. The screw post on its surface facilitates rotation operation. When rotating, the limiting post drives the limiting plate and silicone pad to move upward. The silicone pad adheres to the handwheel body by means of elastic deformation, and uses friction to limit the handwheel body, preventing accidental rotation caused by accidental contact. This solves the problem that some existing regulating valve handwheels have no limit structure and are easily affected by accidental contact, which affects the stability of the desuperheating water regulating valve body. 2. This application incorporates a protective mechanism. The rotating column and the connecting card's rotating hole allow the iron guard plate to rotate. The chamfered corner of the rotating column facilitates insertion into the rotating hole, and the pull ring facilitates operation of the iron guard plate. The tempered glass viewing window on the iron guard plate not only protects the display screen body but also does not obstruct the observation of the displayed content. The magnetic block on the front side of the desuperheating water regulating valve body can limit the movement of the iron guard plate, thus achieving protection for the display screen body and solving the problem of inconvenient protection for the display screens of some existing regulating valves.

[0019] 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.

[0020] Please see Figure 1-7 The present invention provides the following technical solution: A multi-stage throttling desuperheating water regulating valve includes a desuperheating water regulating valve body 1, a handwheel body 3, and a display screen body 7. Connecting clips 5 are provided on both sides of the top of the desuperheating water regulating valve body 1. A limit mechanism 4 is provided on the top of the connecting clips 5. A protective mechanism 2 is provided on the front side of the desuperheating water regulating valve body 1. The limiting mechanism 4 includes a silicone pad 401, a limiting plate 402, a limiting post 403, and a fixed cylinder 404. The bottom of the silicone pad 401 is fixedly connected to the top of the limiting plate 402, the bottom of the limiting plate 402 is rotatably connected to the top of the limiting post 403, and the bottom of the limiting post 403 extends into the interior of the fixed cylinder 404 and is threadedly connected to the interior of the fixed cylinder 404.

[0021] In this embodiment: the connecting card 5 is connected to the desuperheating water regulating valve body 1 by screw 8. The screw 8 passes through the connecting card 5 and is in close contact with the desuperheating water regulating valve body 1. The connection is secured by friction. The guide strip 12 assists in positioning the connecting card 5. By operating the limiting mechanism 4, the silicone pad 401 moves upward and fits against the handwheel body 3. The handwheel body 3 is limited by friction to prevent accidental rotation. The protective mechanism 2 can protect the display screen body 7 and facilitate the operation of the control button of the desuperheating water regulating valve body 1. This solves the problem that some existing multi-stage throttling desuperheating water regulating valves do not have a limiting structure for their handwheels. After adjustment, especially when the multi-stage throttling desuperheating water regulating valve is in a relatively complex operating environment, the handwheel is easily accidentally touched and rotated, causing accidental adjustment of the multi-stage throttling desuperheating water regulating valve, affecting the stability of use, and the display screen is not easily protected.

[0022] Specifically, such as Figure 5 As shown, the protective mechanism 2 includes two rotating posts 201, an iron guard plate 202 and a viewing window 203. The rotating posts 201 are fixedly connected to the iron guard plate 202 on the side closest to the iron guard plate 202. The viewing window 203 is embedded inside the iron guard plate 202. Both the iron guard plate 202 and the viewing window 203 are located on the front side of the display screen body 7.

[0023] Specifically, such as Figure 5 and Figure 7 As shown, each of the two connecting cards 5 has a rotating hole 11 on its front side on the opposite side, and the rotating column 201 is rotatably connected inside the rotating hole 11.

[0024] Specifically, such as Figure 5 As shown, the surface of the rotating column 201 is chamfered, and a pull ring 10 is fixedly connected to the front side of the iron guard plate 202.

[0025] Specifically, such as Figure 1 , Figure 5 and Figure 6 As shown, magnetic blocks 13 are fixedly connected to both sides of the front side of the desuperheating water regulating valve body 1, and the front side of the magnetic blocks 13 is magnetically attracted to the rear side of the iron guard plate 202.

[0026] In this embodiment: the protective mechanism 2 achieves the rotation of the iron guard plate 202 by cooperating with the rotating hole 11 of the connecting card 5 through the rotating column 201, which facilitates the protection of the display screen body 7. The chamfer of the rotating column 201 makes it easy to insert into the rotating hole 11. The pull ring 10 facilitates the rotation of the iron guard plate 202. The tempered glass viewing window 203 allows direct observation of the display content. The magnetic block 13 can attract the iron guard plate 202, enhancing the limiting stability.

[0027] Specifically, such as Figure 4 As shown, a number of screw pins 9 are fixedly connected to the surface of the limiting post 403 and are evenly distributed on the surface of the limiting post 403.

[0028] Specifically, such as Figure 3 As shown, support blocks 6 are fixedly connected to opposite sides of the two connecting cards 5, and the bottom of the fixing cylinder 404 is fixedly connected to the top of the support block 6.

[0029] In this embodiment, the multiple screw pins 9 on the surface of the limiting pin 403 facilitate effortless rotation and improve operational convenience. The support block 6 provides stable support for the fixed cylinder 404, ensuring the overall structural reliability of the limiting mechanism 4.

[0030] Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, guide strips 12 are fixedly connected to both the front and rear sides of the desuperheating water regulating valve body 1, and the surface of the connecting card 5 is in contact with the surface of the guide strip 12.

[0031] Specifically, such as Figure 1 and Figure 3 As shown, screws 8 are provided on the top and bottom of the front and rear sides of the connecting card 5. The side of the screw 8 closest to the connecting card 5 passes through the connecting card 5 and is in close contact with the surface of the desuperheating water regulating valve body 1.

[0032] Specifically, such as Figure 5 As shown, the material of the viewing window 203 is tempered glass.

[0033] In this embodiment: the guide strip 12 assists the connecting card 5 in accurate positioning to ensure installation accuracy; the screw 8 securely connects the connecting card 5 and the desuperheating water regulating valve body 1 through friction to ensure connection reliability; and the tempered glass viewing window 203 combines protection and clear observation function.

[0034] Working principle: The connecting card 5 is connected to the desuperheating water regulating valve body 1 by screws 8 set on the top and bottom of its front and rear sides. The side of the screw 8 near the connecting card 5 passes through the connecting card 5 and is in close contact with the surface of the desuperheating water regulating valve body 1. The friction between the screw 8 and the desuperheating water regulating valve body 1 securely connects the connecting card 5 to the desuperheating water regulating valve body 1. At the same time, guide strips 12 are fixedly connected to both sides of the front and rear sides of the desuperheating water regulating valve body 1. The surface of the connecting card 5 is in contact with the surface of the guide strips 12. With the help of the guide strips 12, the connecting card 5 can be positioned in the correct position. In the limiting mechanism 4 set on the top of the connecting card 5, the opposite sides of the two connecting cards 5 are fixedly connected to the support blocks 6. The bottom of the fixing cylinder 404 and the top of the support blocks 6 are connected to each other. The fixed connection is achieved by extending the bottom of the limiting post 403 into the interior of the fixed cylinder 404 and threadedly connecting it to the interior of the fixed cylinder 404. Several evenly distributed screw posts 9 are fixedly connected to the surface of the limiting post 403. The bottom of the limiting plate 402 is rotatably connected to the top of the limiting post 403. The bottom of the silicone pad 401 is fixedly connected to the top of the limiting plate 402. Rotating the screw posts 9 can drive the limiting post 403 to rotate. Because the limiting post 403 is threadedly connected to the fixed cylinder 404, it moves upward during rotation, thereby driving the limiting plate 402 and the silicone pad 401 to move upward as well. This causes the silicone pad 401 to deform due to its elasticity, conforming to the surface of the handwheel body 3 and making tight contact with it. Friction then limits the movement of the handwheel body 3, preventing... To prevent accidental rotation due to accidental contact, and without limiting its position, the protective mechanism 2 on the front side of the desuperheating water regulating valve body 1 includes two rotating columns 201, an iron guard plate 202, and a viewing window 203. The rotating column 201 is fixedly connected to the iron guard plate 202 on the side closest to it. The viewing window 203 is embedded inside the iron guard plate 202 and is made of tempered glass. Both the iron guard plate 202 and the viewing window 203 are located on the front side of the display screen body 7. Rotating holes 11 are provided on the front sides of the two connecting clips 5 on opposite sides. During the process of connecting the two connecting clips 5 to the desuperheating water regulating valve body 1, the rotating column 201 is moved into the rotating hole 11 and rotatably connected within it. The surface of the rotating column 201 has a chamfer for easy installation. A pull rod is fixedly connected to the front side of the iron guard plate 202. Ring 10 allows the iron guard plate 202 to rotate between the two connecting clips 5 around the rotating column 201 by pulling ring 10, thus facilitating the protection of the display screen body 7. Simultaneously, the display content of the display screen body 7 can be observed through the tempered glass viewing window 203. Magnetic blocks 13 are fixedly connected to both sides of the front of the desuperheating water regulating valve body 1. The front of the magnetic blocks 13 magnetically attracts the rear of the iron guard plate 202, thus limiting the movement of the iron guard plate 202. This achieves protection of the display screen body 7 and facilitates the operation of the control knob of the desuperheating water regulating valve body 1. It solves the problem that some existing multi-stage throttling desuperheating water regulating valves lack a limiting structure in their handwheels, which is particularly problematic after adjustment, especially when the multi-stage throttling desuperheating water regulating valve is in a complex operating environment.The handwheel is easily accidentally turned, causing unintended adjustments to the multi-stage throttling desuperheating water regulating valve, affecting its operational stability. Furthermore, the display screen is not easily protected. It should be noted that the desuperheating water regulating valve body 1 is existing, published, and mature technology. Any content not described in detail in this specification is prior art known to those skilled in the art, and its basic mechanisms will not be elaborated upon here.

[0035] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
