Description

Technical Field

[0001] This utility model relates to the field of blind valve technology, specifically to an impact-resistant hydraulic blind valve. Background Technology

[0002] A blind valve is a gate valve that shuts off gaseous media by hand, electric, pneumatic, or hydraulic means. It is generally classified into electric blind valves, hydraulic blind valves, pneumatic blind valves, closed gate valves, and electric open blind valves. Blind valves are commonly used to control the gas flow in industrial pipelines. In mechanical production, blind valves are used to open or throttle the flow of high and low pressure media through pipelines.

[0003] In existing hydraulic blind valves, the hydraulic mechanism is often exposed on the outside of the valve. During use, the lack of effective protective structures on both sides of the hydraulic mechanism makes it susceptible to damage when the valve is placed in an impact-prone environment. This shortens the service life of the equipment, increases maintenance costs, and may even threaten production safety. Therefore, improvements are necessary. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide an impact-resistant hydraulic blind valve to solve the above problems.

[0005] The purpose of this utility model is achieved as follows: An impact-resistant hydraulic blind valve includes a blind valve body and a hydraulic mechanism. The lower end of the blind valve body is provided with a base, and the upper end of the base is provided with a fixing member for installing the hydraulic mechanism. A first fixing shaft and a second fixing shaft are respectively provided on both sides of the fixing member. The side walls of the first fixing shaft and the second fixing shaft are both provided with countersunk holes. A protective plate is slidably connected to the upper end of the base. The side of the protective plate is provided with a protrusion that matches the countersunk hole. A compression spring is connected between the side wall of the countersunk hole and the protrusion.

[0006] Preferably, a support rod is provided between the flanges of the blind valve body, and a first through hole matching the support rod is provided on the protective plate.

[0007] Preferably, the flange of the blind valve body is provided with a locating pin on the opposite side, and the protective plate is provided with a second through hole that matches the locating pin.

[0008] Preferably, each protective plate has two second through holes, and each second through hole is used in conjunction with a positioning pin.

[0009] Preferably, a connecting plate is provided between the two locating pins.

[0010] Preferably, the protrusion is located at the bottom left corner of the protective plate, and the two second through holes are located next to the right side of the protective plate.

[0011] This utility model has the following beneficial effects:

[0012] 1. In use, the protective plate of this impact-resistant hydraulic blind plate valve shields both sides of the hydraulic mechanism. When the protective plate is subjected to external impact, it slides along the base. At this time, the protrusion compresses the spring in the countersunk hole. The spring absorbs the impact energy through its own elastic deformation, thereby reducing the impact force transmitted to the hydraulic mechanism. When the impact force disappears, the spring returns to its original shape and pushes the protective plate to reset. This structural design provides effective impact protection for the hydraulic mechanism, which can significantly reduce the probability of the hydraulic mechanism being damaged by external impact, thereby extending the service life of the equipment, reducing maintenance costs, and improving safety in the production process.

[0013] 2. A support rod is provided between the flanges of the blind valve body. The protective plate has a first through hole that matches the support rod. During the sliding process of the protective plate, the first through hole moves along the support rod. The support rod provides a guiding effect for the sliding of the protective plate. A locating pin is provided on the opposite side of the flange of the blind valve body. The protective plate has a second through hole that matches the locating pin. The locating pin restricts the left and right offset of the protective plate in the horizontal direction, ensuring that the protective plate is accurately installed in the predetermined position, so that the protrusion and the countersunk hole can be correctly aligned and fitted. The cooperation with the first through hole and the support rod forms a double guiding effect, further enhancing the reliability of the entire impact-resistant structure. Attached Figure Description

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the technical solutions in the specific embodiments of this utility model are clearly and completely described below to further illustrate this utility model. Obviously, the specific embodiments described are only a part of the embodiments of this utility model, and not all of them.

[0022] The following is in conjunction with the appendix Figure 1-4 The present invention will be described in further detail below.

[0023] Example 1:

[0024] An impact-resistant hydraulic blind valve includes a blind valve body 1 and a hydraulic mechanism 2. A base 3 is installed at the lower end of the blind valve body 1. A fixing member 4 for installing the hydraulic mechanism 2 is provided at the upper end of the base 3. A first fixing shaft 5 and a second fixing shaft 6 are respectively provided on both sides of the fixing member 4. The side walls of the first fixing shaft 5 and the second fixing shaft 6 are provided with countersunk holes 7. A protective plate 8 is slidably connected to the upper end of the base 3. The side of the protective plate 8 is provided with a protrusion 9 that matches the countersunk hole 7. A compression spring 10 is connected between the side wall of the countersunk hole 7 and the protrusion 9.

[0025] In use, the protective plate 8 shields both sides of the hydraulic mechanism. When the protective plate 8 is subjected to external impact, it slides along the base 3. At this time, the protrusion 9 compresses the spring 10 inside the countersunk hole 7. The spring 10 absorbs the impact energy through its own elastic deformation, thereby reducing the impact force transmitted to the hydraulic mechanism 2. When the impact force disappears, the spring 10 returns to its original shape, pushing the protective plate 8 to reset. This structural design provides effective impact protection for the hydraulic mechanism 2, significantly reducing the probability of damage to the hydraulic mechanism 2 due to external impact, thereby extending the service life of the equipment, reducing maintenance costs, and improving safety in the production process.

[0026] It should be noted that in the application scenarios applicable to this embodiment, only the front and rear sides of the hydraulic mechanism may be impacted. Users may add anti-impact protection structures in other directions according to actual conditions, which are not within the scope of this utility model.

[0027] In this embodiment, a support rod 11 is provided between the flanges of the blind valve body 1, and a first through hole 12 matching the support rod 11 is provided on the protective plate 8. During the sliding process of the protective plate 8, the first through hole 12 moves along the support rod 11. The support rod 11 provides a guiding function for the sliding of the protective plate 8, ensuring that the protective plate 8 can slide smoothly in a fixed direction and avoid deviation. The cooperation between the support rod 11 and the first through hole 12 improves the stability and accuracy of the sliding of the protective plate 8, enabling the protective plate 8 to play a more reliable role in the impact resistance process and enhancing the reliability of the entire impact resistance structure.

[0028] In this embodiment, the flange of the blind valve body 1 is provided with a positioning pin 13 on the opposite side. The protective plate 8 is provided with a second through hole 14 that matches the positioning pin 13. The positioning pin 13 restricts the offset of the protective plate 8 in the horizontal direction to the left and right sides, ensuring that the protective plate 8 is accurately installed in the predetermined position, so that the protrusion 9 and the countersunk hole 7 can be correctly aligned and cooperate. The cooperation with the first through hole 12 and the support rod 11 forms a double guiding effect, further enhancing the reliability of the entire impact-resistant structure.

[0029] In this embodiment, each protective plate 8 has two second through holes 14. Each second through hole 14 is used in conjunction with a positioning pin 13. The two positioning pins 13 and the two second through holes 14 form a two-point positioning. Compared with single-point positioning, this can more effectively limit the offset of the protective plate 8, so that the protective plate 8 can maintain a stable position when it is impacted, avoid shaking or tilting, and ensure that the hydraulic mechanism 2 can be more stably protected.

[0030] In this embodiment, a connecting plate 15 is provided between the two positioning pins 13. The connecting plate 15 connects the two positioning pins 13 into a whole, which enhances the rigid connection between the positioning pins 13. The connecting plate 15 can block the protective plate 8, which is equivalent to limiting the movement trajectory of the protective plate 8. This limits the travel of the protrusion 9 connected to the protective plate 8 in the countersunk hole 7, that is, the deformation of the compression spring 10 is also limited and will not be over-compressed, reducing the wear of the compression spring 10 and extending the service life of the entire impact-resistant structure.

[0031] like Figure 4 As shown, the protrusion 9 is located at the bottom left corner of the protective plate 8, and the two second through holes 14 are located next to the right side of the protective plate 8, which makes the force distribution of the protective plate 8 more uniform, improves the balance and stability of the protective plate 8 in the process of resisting impact, and ensures that the entire impact-resistant structure can play a more effective role and better protect the hydraulic mechanism 2.

[0032] The working principle of this utility model is as follows: The shock-resistant hydraulic blind valve has a base 3 mounted on the lower end of the valve body 1. A fixing member 4 for mounting the hydraulic mechanism 2 is provided on the upper end of the base 3. A first fixing shaft 5 and a second fixing shaft 6 are respectively provided on both sides of the fixing member 4. The side walls of both the first fixing shaft 5 and the second fixing shaft 6 have inwardly recessed countersunk holes 7. A protective plate 8 is slidably connected to the upper end of the base 3. The side of the protective plate 8 has a protrusion 9 that matches the countersunk hole 7. A compression spring 10 is connected between the side wall of the countersunk hole 7 and the protrusion 9. In use, the protective plate 8 is used to shield and protect both sides of the hydraulic mechanism. When the protective plate 8 is subjected to external impact, it will slide along the base 3. At this time, the protrusion 9 will compress the compression spring 10 inside the countersunk hole 7. The compression spring 10 absorbs the impact energy through its own elastic deformation, thereby reducing the impact force transmitted to the hydraulic mechanism 2. When the impact force disappears, the compression spring 10 returns to its original state, pushing the protective plate 8 to reset. This structural design provides effective impact protection for the hydraulic mechanism 2, significantly reducing the probability of damage to the hydraulic mechanism 2 due to external impact, thereby extending the service life of the equipment, reducing maintenance costs, and improving safety in the production process. A support rod 11 is provided between the flanges of the blind valve body 1, and a first through hole 12 matching the support rod 11 is provided on the protective plate 8. During the sliding process of the protective plate 8, the first through hole 12 moves along the support rod 11, and the support rod 11 provides a guiding effect for the sliding of the protective plate 8. A positioning pin 13 is provided on the opposite side of the flange of the blind valve body 1, and a second through hole 14 matching the positioning pin 13 is provided on the protective plate 8. The positioning pin 13 restricts the left and right offset of the protective plate 8 in the horizontal direction, ensuring that the protective plate 8 is accurately installed in the predetermined position, so that the protrusion 9 and the countersunk hole 7 can be correctly aligned and fitted, forming a double guiding effect with the cooperation of the first through hole 12 and the support rod 11, further enhancing the reliability of the entire impact-resistant structure.

[0033] It should be noted that, depending on the implementation needs, the various components described in the embodiments of this utility model can be divided into more components, or two or more components or parts of components can be combined into new components to achieve the purpose of the embodiments of this utility model. The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be pointed out that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
