Description

Technical Field

[0001] This utility model relates to the field of valve technology, specifically to a valve that is easy to disassemble and assemble. Background Technology

[0002] Valves are control components in fluid transport systems, primarily used for opening and closing pipelines, regulating flow direction, and controlling the parameters of the transported medium (such as temperature, pressure, and flow rate). Their core functions include shut-off, flow diversion, pressure stabilization, and flow splitting, and they are widely used in industries such as industrial, energy, and chemical sectors.

[0003] Authorized inscription number CN215673819U describes a valve comprising a pipeline with connecting flanges at both ends. A valve body, a rectangular box, is mounted on the pipeline. Both ends of the valve body are connected to the pipeline. A hydraulic rod is mounted on the upper end of the valve body, extending beyond the valve body and connecting to an external hydraulic device. A valve is mounted on the lower end of the hydraulic rod. The downward extension of the hydraulic rod causes the valve to move downwards, thereby sealing the pipeline. To address the aforementioned technical problems, this utility model provides a valve that can prevent or reduce wear on valve components.

[0004] However, existing valves are not easy to disassemble quickly after use, which makes it difficult for maintenance personnel to replace and repair the damaged valve core when it is damaged. This affects the maintenance efficiency of the equipment and increases the maintenance and use cost of the equipment.

[0005] Therefore, in order to address the above problems, it is urgent to innovate the design based on the existing valves. Utility Model Content

[0006] The purpose of this utility model is to provide a valve that is easy to disassemble and assemble, so as to solve the problem mentioned in the background art that it is not easy to quickly disassemble the valve after use, which makes it difficult for maintenance personnel to replace and repair the damaged valve core when it is damaged, thus affecting the maintenance and repair efficiency of the device and increasing the maintenance and use cost of the device.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a valve that is easy to disassemble and assemble, comprising: a housing, and a mounting block disposed on the upper side of the housing, wherein a valve core body is mounted on the lower end of the mounting block, and a second sealing ring is disposed on the outer side of the valve core body;

[0008] Also includes:

[0009] A flow channel is provided on the outside of the outer shell of the machine body. An operating block is provided on the outside of the mounting block, and a support block is connected to the inside of the operating block. A guide block is provided inside the support block, and a series arc plate is connected to the upper side of the support block. A connecting groove is provided on the upper side of the outer shell of the machine body.

[0010] The first positioning block is installed in the middle of the mounting block, and the mounting block is equipped with a separation drive assembly. The lower end of the valve core body is connected to the second positioning block, and the upper side of the valve core body is provided with a connecting block. The outer side of the connecting block is provided with a mounting bracket, and the outer side of the mounting bracket is provided with a third positioning block.

[0011] In one possible implementation, the support block and the guide block are rotatably connected relative to each other, and the support block is symmetrically arranged about the central axis of the mounting block.

[0012] In one possible implementation, the series arc plate is slidably connected to both the mounting block and the outer casing, and the longitudinal section of the series arc plate is a "T" shaped structure.

[0013] In one possible scenario, the first positioning block is engaged with the outer shell of the machine body, and the cross-section of the first positioning block is a "T" shaped structure.

[0014] In one possible scenario, the valve core body is rotatably connected to the second positioning block and the mounting bracket, and the second sealing ring is symmetrically arranged about the central axis of the valve core body.

[0015] In one possible scenario, the mounting bracket engages with the third positioning block.

[0016] In one possible implementation, the separation drive assembly includes a preset slot formed inside the mounting block, and a guide rod is provided inside the preset slot. A reset spring is nested at the lower end of the guide rod, and a reset plate is connected to the upper side of the reset spring. An operating handle passes through the middle of the reset plate, and a drive block is connected to the lower end of the operating handle.

[0017] The reset plate and the guide rod are slidably connected, and the guide rod is symmetrically arranged about the central axis of the reset plate.

[0018] In one possible implementation, the operating handle is rotatably connected to the reset plate, and the driving block at the lower end of the operating handle is engaged with the connecting block.

[0019] Compared with the prior art, the beneficial effects of this utility model are: the valve, which is easy to disassemble and assemble, can be quickly disassembled after use, making it easy for maintenance personnel to replace and repair the damaged valve core when it is damaged, thus avoiding affecting the maintenance efficiency of the device and reducing the maintenance and use costs of the device. At the same time, it is easy to separate the valve core from the operating handle during the use of the device, making it less likely to cause valve core movement accidents due to accidental contact or collision during use, improving the stability of the device and providing better performance. Specifically, as shown below:

[0020] 1. The reset plate is pushed upward by the reset spring and the guide rod, so that the reset plate pushes the internal operating handle and the drive block to slide upward and reset. At this time, the drive block is disengaged from the inside of the connecting block, which prevents the operating handle from being hit by external objects during idle time, thus preventing the valve core body and the connecting block from rotating inside the machine body and improving the stability of the device.

[0021] 2. By using the operating block and the support block to push the series arc plate to rotate along the guide block on the mounting block, the rapidly rotating series arc plate repeatedly unlocks or connects the mounting block and the outer shell of the machine body. This makes it easy for operators to quickly disassemble and assemble the device when it is not in use, reducing the labor intensity of disassembly and assembly and improving the use effect of the device.

[0022] 3. The valve core body and connecting block are positioned and disassembled by the mounting bracket and the third positioning block, so that maintenance personnel can quickly replace the valve core body when it is damaged. This avoids the need to replace the entire device when the valve core body is damaged, reducing the maintenance cost and downtime of the device. Attached Figure Description

[0029] 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.

[0030] Please see Figure 1-5 This utility model provides a technical solution: a valve that is easy to disassemble and assemble, including a housing 1, a flow groove 2, a preset hole 3, a mounting block 4, an operating block 5, a support block 6, a guide block 7, a series arc plate 8, a connecting groove 9, a first positioning block 10, a preset groove 11, a guide rod 12, a return spring 13, a return plate 14, an operating handle 15, a drive block 16, a first sealing ring 17, a valve core body 18, a second sealing ring 19, a second positioning block 20, a connecting block 21, a mounting bracket 22, and a third positioning block 23.

[0031] Specifically, such as Figure 1 , Figure 3 and Figure 5As shown, during the use of the device, by connecting the pipe to the outside of the flow channel 2, the connecting bolt is passed through the inside of the preset hole 3 to connect the device and the pipe in series, so that the liquid inside the pipe flows to the other side through the inside of the outer shell 1 and the valve core body 18. At this time, the first sealing ring 17 set on the lower side of the mounting block 4 fills the gap between the outer shell 1 and the mounting block 4 to prevent the fluid from seeping to the outside of the device through the connection between the two. At the same time, the second sealing ring 19 set on the outside of the valve core body 18 fills the gap between the mounting block 4 and the valve core body 18 to prevent the fluid from entering the inside of the preset channel 11 through the gap between the valve core body 18 and the mounting block 4. At this time, the operating handle 15 is pressed down, so that the operating handle 15 pushes the reset plate 14 connected to its lower side to move downward and squeeze the reset spring 13. Due to the sliding connection structure between the guide rod 12 and the reset plate 14, the reset plate 14 is guided and limited by the guide rod 12 during the downward movement, so as to prevent the reset plate 14 from shifting position during the up and down movement. At this time, because of the drive The engaging connection structure between the moving block 16 and the connecting block 21 allows the downward-moving operating handle 15 to effectively connect with the connecting block 21 and the valve core body 18. Rotating the operating handle 15 on the upper side of the reset plate 14 causes the operating handle 15 to push the valve core body 18 and the connecting block 21 connected to it below to rotate inside the second positioning block 20 and the mounting bracket 22. The valve core body 18, rotating 90 degrees, cuts off the internal space of the device, causing the liquid flowing to the other side to be interrupted and paused, thus completing the opening and closing of the fluid. After the closing operation is completed, releasing the pressure on the operating handle 15 causes the compressed return spring 13 to lose its pressure and generate a rebound force. The return spring 13 then pushes the reset plate 14 connected to it above to reset upwards along the guide rod 12, causing the driving block 16 to disengage from the interior of the connecting block 21 and reset upwards. This prevents the operating handle 15 from being impacted by external objects during idle periods, thus preventing the valve core body 18 and the connecting block 21 from rotating inside the outer casing 1 and improving the stability of the device.

[0032] Specifically, such as Figure 1 , Figure 2 and Figure 4As shown, when the valve core body 18 is damaged, the operating block 5 on the outer side of the rotating mounting block 4 causes the operating block 5 to drive the support block 6 connected to its inner side to rotate on the outer side of the mounting block 4. At this time, due to the rotational connection structure between the guide block 7 and the support block 6, the support block 6 is guided and limited by the guide block 7 during the rotation process, preventing the support block 6 from tilting at an angle during the rotation. At this time, the rotating support block 6 drives the upper connected series arc plate 8 to rotate upward, so that the upper rotating series arc plate 8 disengages from the inside of the connecting groove 9 and returns to the inside of the mounting block 4, making it easy for the operator to pull the mounting block 4 upward to remove it. This causes the mounting block 4 to drive the valve core body 18 and the second sealing ring 19 on its lower side to disengage from the inside of the machine housing 1. At this time, the valve core body 18 is pulled downward, and due to the engaging connection structure between the mounting bracket 22 and the third positioning block 23, the valve core body 18 drives the upper connected connecting block 2 1. The mounting bracket 22 is separated from the third positioning block 23 and the mounting block 4, making it easier for operators to inspect and replace the valve core body 18 and the second sealing ring 19. At this time, the brand-new valve core body 18 and connecting block 21 are reinstalled along the mounting bracket 22 at the lower end of the mounting block 4. Due to the engaging connection structure between the first positioning block 10 and the mounting block 4, the operator can easily reposition and install the mounting block 4 on the upper side of the housing 1. At the same time, the operating block 5 on the outside of the mounting block 4 is rotated in the opposite direction, so that the operating block 5, together with the support block 6, pushes the series arc plate 8 to rotate downward. At this time, the series arc plate 8 re-inserts into the interior of the connecting groove 9 to limit the series connection between the mounting block 4 and the housing 1, thereby completing the quick disassembly and maintenance of the device, reducing the labor intensity of maintenance personnel, avoiding the need to replace the entire device when the valve core body 18 is damaged, and reducing the maintenance cost of the device.
