Description

Technical Field

[0001] This utility model relates to the field of electric regulating valve technology, specifically a high-efficiency self-protecting electric regulating valve. Background Technology

[0002] Electric control valves can precisely control fluid parameters during use. They receive control signals via an electric actuator, driving internal valve components to change the valve opening and ultimately achieve automatic regulation of process parameters such as flow rate, pressure, temperature, and liquid level. Electric control valves are widely used in industrial fields. However, during valve use, in densely packed industrial environments, the valve body may be too close to adjacent pipes, valves, or equipment casings. When pipes expand or contract due to thermal expansion or contraction, or when the medium vibrates due to impact, the valve body side may intermittently collide or rub against adjacent objects, leading to valve wear. To overcome this defect, prior art 1 (Chinese patent application No. 202121777945.6, application date 2021-08-02) describes a control valve with wear resistance. During use, the control valve utilizes the cooperation between the connecting pipe and the wear-resistant ring to ensure the valve's quality. This avoids the problem that if the control valve itself lacks wear resistance, prolonged friction with other parts will reduce its sealing performance and consequently decrease the efficiency of the device.

[0003] Before using an electric control valve, it needs to be connected to the required position via a connecting flange. The flange is one of the important components of the valve body. When connecting the connecting flange on the valve body to the connecting flange on the pipeline, a wrench is needed to tighten the bolts. If the operation is improper, such as the wrench slipping, the wrench may hit the outer edge of the flange, causing wear on the outer edge of the flange, which will affect the overall service life of the valve body. However, the device in the above application does not have the wear-resistant structure of the connecting flange during use. Once the flange is damaged, the valve body will fall off, which will lead to an accident in the entire pipeline. Utility Model Content

[0004] The purpose of this utility model is to provide a highly efficient and self-protective electric regulating valve to solve the problem mentioned in the background art that it does not have a wear-resistant connecting flange structure during use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency self-protecting electric regulating valve, comprising a valve body, wherein connecting flanges are fixedly connected to both the left and right sides of the valve body, and a fixing block is fixedly connected to the upper surface of the connecting flange, and a protective plate is connected to the surface of the fixing block through a snap-fit ​​assembly; a locking block is slidably disposed inside the fixing block, and a handle is fixedly connected to the end of the locking block; a connecting block is fixedly connected to the upper surface of the protective plate, and a push rod is slidably disposed inside the connecting block, and a connecting plate is fixedly connected to the inner wall of the protective plate.

[0006] Preferably, the engaging assembly includes an external rod fixedly connected to the surface of the connecting block, and the upper surface of the external rod has a slot corresponding to the engaging block, and the surface of the fixing block has a deep groove corresponding to the external rod.

[0007] Preferably, sliders are fixedly connected to both the left and right sides of the card block, and the surface of the card block is inclined.

[0008] Preferably, the fixed block has a groove inside that corresponds to the slider, and a first spring that plays an elastic reset role is fixedly connected to the upper surface of the slider, and the other side of the first spring is fixedly connected to the inner wall of the fixed block.

[0009] Preferably, the protective plates are symmetrically distributed on both sides of the connecting flange, and the protective plates have an arc-shaped structure. The surface of the connecting plate is provided with through holes corresponding to the mounting holes of the connecting flange.

[0010] Preferably, the surface of the push rod is in contact with the inner wall of the fixing block.

[0011] Preferably, a second spring is fixedly connected to the surface of the push rod, and the other side of the second spring is fixedly connected to the inner wall of the connecting block.

[0012] Compared with the prior art, the beneficial effects of this utility model are: this high-efficiency self-protecting electric regulating valve adopts a novel structural design, the specific details of which are as follows: (1) When the high-efficiency self-protecting electric regulating valve needs to be connected to the protective plate during use, the external rod is inserted into the deep groove. At this time, the surface of the external rod will push the locking block, causing the locking block to move the slider in the direction of squeezing the first spring. After the external rod contacts the bottom of the deep groove, the locking block descends under the action of the first spring and the slider. At this time, the locking block enters the deep groove, and then the connecting block and the protective plate engage with the connecting flange. The protective plate plays a role in protecting the connecting flange, extending the service life of the connecting flange, and thus enabling the valve body to work better.

[0013] Furthermore, during the docking process, the external rods and deep grooves correspond one-to-one, which plays an auxiliary positioning role, increases the speed of the docking process, and thus improves work efficiency.

[0014] Furthermore, during the movement of the card block, the slider and groove limit the movement distance of the card block, ensuring stability.

[0015] (2) When the protective plate needs to be disassembled, the handle at the end of the card block is pulled. At this time, the handle drives the end of the card block to move out of the card slot, so that the protective plate and the connecting block are not locked with the fixed block. At this time, the external rod can be pulled out to the outside, and the disassembly process is efficient and quick.

[0016] (3) During the docking process of the protective plate, the push rod of the high-efficiency self-protecting electric regulating valve will be pushed by the surface of the fixed block and move into the interior of the connecting block. At this time, the second spring is squeezed. After the handle moves the end of the card block out of the slot, the push rod pushes the fixed block under the action of the second spring. At this time, the push rod and the connecting block quickly leave the fixed block under the action of the counter-thrust. At this time, the push rod and the second spring play an auxiliary role in disassembly, simplifying the disassembly steps. Attached Figure Description

[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] This utility model provides the following technical solution: a high-efficiency self-protecting electric regulating valve.

[0021] Example 1: The locking block 8 and locking groove 7 allow the protective plate 4 to quickly mate with the connecting flange 2, thus protecting the connecting flange 2. Figures 1-5 As shown, the valve body includes a valve body 1, with connecting flanges 2 fixedly connected to both the left and right sides of the valve body 1. A fixing block 3 is fixedly connected to the upper surface of the connecting flange 2, and a protective plate 4 is connected to the surface of the fixing block 3 through a snap-fit ​​assembly. A locking block 8 is slidably arranged inside the fixing block 3.

[0022] The engaging assembly includes an external rod 6 fixedly connected to the surface of the connecting block 5, and the upper surface of the external rod 6 is provided with a slot 7 corresponding to the locking block 8, and the surface of the fixing block 3 is provided with a deep groove 9 corresponding to the external rod 6.

[0023] Slider blocks 10 are fixedly connected to both the left and right sides of the locking block 8, and the surface of the locking block 8 is inclined. The inside of the fixing block 3 is provided with sliding grooves 14 that correspond one-to-one with the sliders 10. The upper surface of the sliders 10 is fixedly connected with a first spring 11 that plays an elastic reset role. The other side of the first spring 11 is fixedly connected to the inner wall of the fixing block 3. The protective plates 4 are symmetrically distributed on both sides of the connecting flange 2. The protective plates 4 are arc-shaped. A connecting plate 15 is fixedly connected to the inner wall of the protective plate 4. The surface of the connecting plate 15 is provided with through holes that correspond to the mounting holes of the connecting flange 2.

[0024] During use, when the protective plate 4 needs to be connected, the external rod 6 is inserted into the deep groove 9. At this time, the surface of the external rod 6 will push the locking block 8, causing the locking block 8 to drive the slider 10 to move in the direction of squeezing the first spring 11. After the external rod 6 contacts the bottom of the deep groove 9, the locking block 8 descends under the action of the first spring 11 and the slider 10. At this time, the locking block 8 enters the deep groove 9, and then the connecting block 5 and the protective plate 4 engage with the connecting flange 2 (e.g., Figure 4 As shown in the figure, the protective plate 4 protects the connecting flange 2, extends the service life of the connecting flange 2, and enables the valve body 1 to work better. During the docking process, the external rod 6 and the deep groove 9 correspond one-to-one, playing an auxiliary positioning role, increasing the speed of the docking process, and thus improving work efficiency.

[0025] The connecting plate 15 serves to protect the mounting surface of the connecting flange 2, while the through holes on the surface of the connecting plate 15 allow the connecting flange 2 to be installed and connected normally.

[0026] Example 2: Unlike Example 1, a handle is provided to allow the card block 8 to be quickly pulled out of the card slot 7, such as... Figure 4As shown, a handle is fixedly connected to the end of the locking block 8. When it is necessary to inspect and disassemble the protective plate 4 and the connecting flange 2, the handle at the end of the locking block 8 is pulled. At this time, the handle moves the end of the locking block 8 out of the slot 7, so that the protective plate 4 and the connecting block 5 are not locked with the fixed block 3. At this time, the external rod 6 can be pulled out to the outside. The disassembly process is efficient and quick.

[0027] Example 3: Unlike Example 2, the push rod 12 and the second spring 13 assist in disassembly. Figure 6 and Figure 7 As shown, a connecting block 5 is fixedly connected to the upper surface of the protective plate 4, and a push rod 12 is slidably arranged inside the connecting block 5. The surface of the push rod 12 is in contact with the inner wall of the fixed block 3. A second spring 13 is fixedly connected to the surface of the push rod 12, and the other side of the second spring 13 is fixedly connected to the inner wall of the connecting block 5.

[0028] During the docking process of the protective plate 4, the push rod 12 is pushed by the surface of the fixing block 3 and moves into the interior of the connecting block 5. At this time, the second spring 13 is compressed (e.g., Figure 6 and Figure 7 As shown), after the handle moves the end of the locking block 8 out of the slot 7, the push rod 12 pushes the fixing block 3 under the action of the second spring 13. At this time, the push rod 12 and the connecting block 5 quickly leave the fixing block 3 under the action of the counter-pushing force. At this time, the push rod 12 and the second spring 13 play an auxiliary role in disassembly, simplifying the disassembly steps.

[0029] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
