Description

Technical Field

[0001] This utility model belongs to the technical field of protective sleeve devices, specifically relating to a valve body protection device that is easy to install. Background Technology

[0002] Valves are control components in fluid transport systems, and have functions such as shutting off, regulating, guiding, preventing backflow, stabilizing pressure, diverting flow, or overflowing and relieving pressure.

[0003] In the prior art, Chinese utility model patent with authorization announcement number CN219263311U discloses "a protective sleeve for a valve", which includes a valve assembly, a protective assembly, and a sleeve assembly. The valve assembly includes a valve body, a delivery pipe, and a flange. The two ends of the valve body are connected to the delivery pipe through the flange. The protective assembly includes a first housing and a second housing. An isolation layer is connected to the inner wall of the first housing. An inner partition layer is connected to the end of the isolation layer away from the first housing. A protective side layer is connected to the inner wall of the first housing. A rubber layer is connected to the inner wall of the clearance groove.

[0004] However, the valve protective sleeves described above still have aspects that need improvement in actual operation and maintenance scenarios: the assembly and fixation of the first and second shells rely on a "connecting lug + bolt" mating structure. Although this structure can ensure the stability after assembly, when it is necessary to disassemble the shell to maintain the valve body (such as inspecting the valve sealing performance or replacing the flange gasket) or protective components (such as replacing the aging inner partition or insulation layer), it is necessary to use specific tools such as wrenches to complete the bolt disassembly operation. This design can easily cause many inconveniences in practical applications: for example, in outdoor pipelines, high-altitude valves, or dense pipeline scenarios with narrow spaces, the carrying of tools and the operating space are limited, which not only leads to low shell disassembly efficiency and delays in maintenance progress; if a sudden valve failure occurs (such as flange leakage) and there is a lack of corresponding tools on site, it may be impossible to disassemble the protective sleeve in time for emergency treatment, thereby affecting the normal operation of the fluid transportation system and even increasing safety hazards.

[0005] To address the aforementioned problems, this application proposes a valve body protection device that is easy to install. Utility Model Content

[0018] 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. Example

[0019] Please see Figures 1-6 The present invention provides the following technical solution: a valve body protection device that is easy to install, including a valve body body 1 and a protective shell sleeved on the outside of the valve body body 1. The protective shell includes a first outer shell 2 and a second outer shell 3 sleeved on the outer wall of the valve body body 1 and symmetrically arranged. It also includes two sets of connecting components 100, which are respectively disposed on the first outer shell 2 and the second outer shell 3, for realizing the quick splicing and fixing of the first outer shell 2 and the second outer shell 3; in use, the initial angle of the first outer shell 2 and the second outer shell 3 is first adjusted according to the installation position of the valve body 1 (such as pipeline height, surrounding space) so that the protective structure of the inner wall of the first outer shell 2 and the second outer shell 3 (such as the arc groove adapted to the valve body, the sealing gasket layer) can be accurately aligned with the outer wall contour of the valve body 1; Subsequently, the first outer shell 2 and the second outer shell 3 are fastened together from both sides of the valve body 1 towards the middle until the splicing surfaces of the first outer shell 2 and the second outer shell 3 are in contact. At this time, the two sets of connecting components 100 will enter the matching state as the shells are fastened together. Without the aid of additional tools, the splicing and fixing of the first outer shell 2 and the second outer shell 3 can be quickly completed by manual operation, thereby achieving efficient protection of the valve body 1.

[0020] Preferably, by Figure 1 , Figure 3 , Figure 4 and Figure 6 As shown, in this embodiment, the connecting component 100 includes two limiting frames 107 symmetrically arranged on the outer wall of the first housing 2, and each of the two limiting frames 107 is provided with a second mounting hole 108. Two fixing brackets 101 are symmetrically arranged on the outer wall of the second outer shell 3. Each fixing bracket 101 has a first mounting hole 102 that matches the second mounting hole 108. A bidirectional threaded rod 103 is rotatably connected to the fixed frame 101. One end of the bidirectional threaded rod 103 passes through the fixed frame 101 and is fixedly connected to a rotary vane 106. Two connecting blocks 104 are symmetrically connected to the outer wall of the bidirectional threaded rod 103 by threads. One end of the connecting block 104 passes through the first mounting hole 102 and is fixedly provided with a limiting member 105. When in use, if the first outer shell 2 and the second outer shell 3 need to be installed on the valve body 1, first rotate the rotary vane 106 to drive the bidirectional threaded rod 103 to rotate on the fixed frame 101. Since the outer wall of the bidirectional threaded rod 103 is symmetrically connected to two connecting blocks 104 by threads, the rotation of the bidirectional threaded rod 103 will drive the two connecting blocks 104 to move towards or away from each other, thereby adjusting the position of the two limiting members 105 so that the limiting members 105 are aligned with the position of the first mounting hole 102. Subsequently, the limiting bracket 107 on the first outer shell 2 is aligned with the fixing bracket 101 on the second outer shell 3, so that the second mounting hole 108 and the first mounting hole 102 are on the same straight line. At this time, the first outer shell 2 and the second outer shell 3 are fastened together until the splicing surfaces are in contact. At this time, the limiting member 105 will pass through the second mounting hole 108, and then the rotating plate 106 will be rotated clockwise. The bidirectional threaded rod 103 will drive the two connecting blocks 104 to move in opposite directions, thereby driving the limiting member 105 to move into the first mounting hole 102 until one side of the limiting member 105 is engaged with one side of the limiting bracket 107, thus realizing the fixed connection between the first outer shell 2 and the second outer shell 3.

[0021] Preferably, by Figure 1 , Figure 2 and Figure 5 As shown, in this embodiment, a top cover 4 is also included. Two pairs of support frames 5 are fixedly provided at the bottom of the top cover 4, and each pair of support frames 5 is provided with a clearance hole 6. Two mounting brackets 12 are fixedly installed on the outer walls of both the first outer shell 2 and the second outer shell 3. A connecting bracket 9 is fixedly installed at the bottom of the mounting bracket 12. A screw 10 is rotatably connected to the connecting bracket 9 via a rotating shaft. An adjusting post 11 is threaded onto the outer wall of the screw 10. A square hole 8 is provided on the mounting bracket 12 for the screw 10 to pass through. In use, if the top cover 4 needs to be assembled onto the first outer shell 2 and the second outer shell 3, the two pairs of support brackets 5 at the bottom of the top cover 4 can be placed on the mounting brackets 12 on the outer walls of the first outer shell 2 and the second outer shell 3 respectively to ensure that the support brackets 5 stably support the top cover 4. Then, the screw 10 on the connecting bracket 9 is flipped so that the screw 10 passes through the square hole 8 of the mounting bracket 12 and the clearance hole 6 of the support bracket 5 in sequence until the top of the screw 10 extends above the clearance hole 6. Next, rotate the adjusting column 11 clockwise. Because the inner wall of the adjusting column 11 is provided with a thread that matches the outer wall of the screw 10, the adjusting column 11 will move downward along the axis of the screw 10 under the action of the thread engagement. Continue to rotate the adjusting column 11 until its bottom end is tightly abutted against the top of the support frame 5. Through the bidirectional limiting of the adjusting column 11 and the mounting frame 12, the support frame 5 is firmly fixed on the mounting frame 12, thereby completing the installation and fixing of the top cover 4. After the top cover 4 is installed, it can completely cover the first outer shell 2 and the second outer shell 3, effectively blocking sunlight and rainwater from directly affecting the first outer shell 2 and the second outer shell 3, preventing the two shells from aging and rusting due to long-term exposure to the outdoor environment, and preventing rainwater from seeping into the protective shell and affecting the normal operation of the valve body 1, further extending the service life of the entire valve body protection device.

[0022] Preferably, by Figure 1 , Figure 2 and Figure 5As shown, in this embodiment, baffles 7 are provided on both sides of the clearance hole 6 on the support frame 5; when the adjusting column 11 is tightly pressed against the top of the support frame 5, its outer wall will just abut against one side of the baffle 7. At this time, the baffle 7 can effectively limit the adjusting column 11 and restrict the adjusting column 11 from moving arbitrarily. Under this structure, the screw 10 can be adjusted to move the adjusting column 11 upward to a specific distance, allowing the adjusting column 11 to disengage from the baffle 7 before the screw 10 can be flipped to remove the top cover 4. In daily use, since the adjusting column 11 is always limited by the baffle 7 and cannot move upward at will, the screw 10 can be effectively prevented from accidentally coming out of the clearance hole 6, thereby significantly improving the stability of the top cover 4 after installation and ensuring its top protection effect on the first outer shell 2 and the second outer shell 3.

[0023] Preferably, by Figure 1 , Figure 2 and Figure 5 As shown, in this embodiment, reinforcing ribs 13 are fixedly provided on both pairs of support frames 5, and the other side of the reinforcing ribs 13 is fixedly connected to the bottom of the top cover 4. The setting of the reinforcing ribs 13 further enhances the structural strength of the support frame 5, so that the top cover 4 can be more stably supported on the top of the first outer shell 2 and the second outer shell 3 after installation, and is not easy to shake or deform due to external forces (such as wind pressure, people stepping on it), thereby further improving the structural stability and safety of the entire valve body protection device.

[0024] Preferably, by Figure 1 and Figure 6 As shown, in this embodiment, the width of the limiting member 105 is smaller than the width of the second mounting hole 108; this allows the limiting member 105 to pass smoothly through the second mounting hole 108, avoiding the problem of installation obstruction due to size mismatch during installation and improving installation efficiency.

[0025] Preferably, by Figure 1 and Figure 5 As shown, in this embodiment, the height of the screw 10 is greater than the height of the baffle 7; so that after the top cover 4 is installed on the first housing 2 and the second housing 3, the top of the screw 10 can extend above the clearance hole 6, providing sufficient rotation space for the adjusting column 11, ensuring that the adjusting column 11 can move smoothly downward along the axis of the screw 10 until it is tightly abutted against the top of the support frame 5, thus completing the installation and fixing of the top cover 4.

[0026] Components not described in detail in this article are existing technologies.

[0027] The working principle and usage process of this utility model: When in use, start the pre-adjustment of the connecting component 100: manually rotate the rotating plate 106 on the fixing frame 101 of the second outer shell 3. The rotating plate 106 drives the bidirectional threaded rod 103 to rotate. Because the threads on the outer wall of the bidirectional threaded rod 103 are symmetrical, the two connecting blocks 104 will move towards each other until the limiting member 105 is aligned with the first mounting hole 102 of the fixing frame 101, which prepares for subsequent splicing. Next, the first outer shell 2 and the second outer shell 3 are fastened together from both sides of the valve body 1 towards the middle. During the process, the limiting frame 107 of the first outer shell 2 and the fixing frame 101 of the second outer shell 3 are aligned simultaneously to ensure that the second mounting hole 108 of the limiting frame 107 and the first mounting hole 102 of the fixing frame 101 are coaxial. After the splicing surfaces of the two outer shells are completely fitted, the rotating plate 106 is rotated clockwise. The bidirectional threaded rod 103 drives the connecting block 104 to drive the limiting member 105 to move in opposite directions until the limiting member 105 passes through the second mounting hole 108 and is snapped into one side of the limiting frame 107, thus completing the fixing of the first outer shell 2 and the second outer shell 3. At this time, the protective shell completely covers the valve body 1, and the inner wall protection structure (such as the sealing gasket layer) is tightly fitted with the outer wall of the valve body, thus initially achieving the protection of the valve body. If the valve body is in an outdoor environment, a top cover 4 needs to be installed: Place the two pairs of support brackets 5 at the bottom of the top cover 4 onto the mounting brackets 12 of the first outer shell 2 and the second outer shell 3, ensuring that the clearance hole 6 of the support bracket 5 is aligned with the square hole 8 of the mounting bracket 12; then flip the screw 10 on the connecting bracket 9 so that the screw 10 passes through the square hole 8 and the clearance hole 6 in sequence until the top of the screw 10 extends above the clearance hole 6; rotate the adjusting column 11 clockwise, and use the threaded engagement to drive the adjusting column 11 to move downward along the screw 10 until the bottom end of the adjusting column 11 tightly presses against the top of the support bracket 5, and the outer wall of the adjusting column 11 abuts against the baffles 7 on both sides of the support bracket 5. The baffles 7 limit the adjusting column 11 to prevent the screw 10 from accidentally coming out, and finally complete the fixing of the top cover 4; In daily use, the top cover 4 enhances structural stability through the reinforcing ribs 13 at the bottom, effectively blocking sunlight and rain from invading the first outer shell 2 and the second outer shell 3, preventing the outer shell from aging and rusting, and preventing rainwater from seeping into the protective shell. If the valve body 1 needs to be inspected, first rotate the adjusting column 11 counterclockwise to move the adjusting column 11 upward and disengage it from the baffle 7, then flip the screw 10 to exit the clearance hole 6 and remove the top cover 4; then rotate the rotating plate 106 of the connecting component 100 counterclockwise to disengage the limiting member 105 from the limiting frame 107, thereby separating the first outer shell 2 and the second outer shell 3 and exposing the valve body 1 for maintenance. The entire device does not require complex tools from installation to disassembly, taking into account both protection reliability and ease of operation and maintenance.

[0028] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the 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.
