Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment technology, specifically a pneumatic parallel double gate valve. Background Technology

[0002] The pneumatic parallel double gate valve is a valve specifically designed for fluid control in industrial pipelines. It is characterized by its parallel double gate structure and the use of a pneumatic actuator to control the valve.

[0003] The existing double gate valve core is located inside the valve body. It is used in combination with a spring and a push rod to allow the double gate valve core to expand or contract to both sides at the same time to block the fluid. If one side of the valve core is damaged, the existing spring is fixedly connected to the double gate valve core, so the entire double gate valve core needs to be replaced, which is wasteful. At the same time, disassembling the ordinary double gate valve core during maintenance takes a long time, which reduces maintenance efficiency.

[0004] The reason for this problem is that the fluid has different effects on the gate valve core. The side in contact with the fluid is easily corroded, which means that when replacing one side of the gate, the undamaged gate needs to be removed together, resulting in a waste of resources. At the same time, due to the unique structure of the ordinary double gate valve core, the disassembly time is long, and the length of downtime directly affects production efficiency and economic benefits. Therefore, we propose a new type of pneumatic parallel double gate valve to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a pneumatic parallel double gate valve. It solves the problem that existing double gate valve cores are located inside the valve body, using a combination of springs and push rods to allow the double gate valve core to expand or contract simultaneously to block fluid. However, if one side of the valve core is damaged, because the existing springs are fixedly connected to the double gate valve core, the entire double gate valve core needs to be replaced, resulting in waste. Furthermore, during maintenance, disassembling a standard double gate valve core is time-consuming, reducing maintenance efficiency.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a pneumatic parallel double gate valve, including a valve body, wherein a double gate valve core is provided inside the valve body, and a quick disassembly device is provided on the inner top of the double gate valve core, wherein the quick disassembly device includes a first magnet, a insert, a first spring and a fixing box;

[0007] The insert is movably inserted into both sides of the fixing box, and the inserts are connected to each other by a first spring. The first magnet is fixedly connected to the other side of the insert.

[0008] Preferably, a second magnet is fixedly connected to both sides of the fixing box, the first magnet and the second magnet are magnetically connected, a fixing seat is fixedly installed on the inner wall of the double gate valve core, and the first magnet is movably inserted into the inside of the fixing seat.

[0009] Preferably, the double gate valve core is provided with an adjusting component, which includes a push rod and a second spring;

[0010] The push rod is movably inserted into the inside of the double gate valve core, the second spring is wound around the outer surface of the push rod, one end of the second spring abuts against the double gate valve core, and the other end of the second spring is fixedly connected to the push rod.

[0011] Preferably, the adjusting component further includes a wedge block, a slot, and an arc block;

[0012] The double gate valve core has a groove inside, the arc-shaped block is fixedly connected inside the groove, the wedge-shaped block is fixedly connected to the end of the push rod, and the wedge-shaped block abuts against the arc-shaped block.

[0013] Preferably, sealing rings are fixedly connected to both sides of the valve body, and the outer surface of the sealing rings abuts against the double gate valve core.

[0014] This utility model discloses a pneumatic parallel double gate valve, which has the following beneficial effects: the device enables quick disassembly of the double gate valve, reduces the time required for maintenance, improves maintenance efficiency, and allows for individual replacement of damaged gate valve cores, avoiding the phenomenon of replacing the entire valve when only one side is damaged, thus avoiding waste and meeting the needs of users.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] This application provides a pneumatic parallel double gate valve, which solves the problem that existing double gate valve cores are located inside the valve body and are used in combination with springs and push rods to allow the double gate valve cores to expand or contract to both sides simultaneously to block fluid. However, if one side of the valve core is damaged, the existing springs are fixedly connected to the double gate valve core, so the entire double gate valve core needs to be replaced, which is wasteful. At the same time, disassembling ordinary double gate valve cores during maintenance is time-consuming and reduces maintenance efficiency.

[0023] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0024] This utility model discloses a pneumatic parallel double gate valve.

[0025] According to the appendix Figure 1-4 As shown, it includes a valve body 1, inside which a double gate valve core 2 is provided, and on the inner top of the double gate valve core 2 is a quick disassembly device 3, which includes a first magnet 32, a strip 33, a first spring 34 and a fixing box 35.

[0026] When the device needs adjustment, the push-pull cylinder is activated upwards, and the push rod 41 is fixedly connected to the output end of the push-pull cylinder, causing the push rod 41 to move upwards synchronously, driving the double gate valve core 2 upwards as well. The first spring 34 tightens, pulling the insert 33 into the fixed box 35. The first magnet 32 ​​and the second magnet 36 are magnetically connected, pulling the double gate valve core 2 inwards, thus opening the valve body 1. When closing is required, the push-pull cylinder drives the push rod 41 downwards, causing the double gate valve core 2 to move downwards synchronously. The wedge block 43 inserts into the arc block 45, opening the double gate valve core 2. The gate valve core 2 abuts against the sealing ring 5 to close the valve body 1. When the double gate valve core 2 needs to be disassembled, the fixing box 35 is lifted upwards, so that the first magnet 32 ​​is disengaged from the fixing seat 31. At this time, the damaged gate valve core can be removed and replaced with a new gate valve core. The first magnets 32 on both sides of the fixing box 35 are inserted into the interior of the fixing seat 31 to fix the double gate valve core 2, thus meeting the user's needs. The quick disassembly device 3 is installed on both sides inside the double gate valve core 2 to ensure its sealing effect and prevent the double gate valve core 2 from falling off, thus ensuring the normal use of the device.

[0027] Insert strip 33 is movably inserted into both sides of fixed box 35. Insert strip 33 is connected to each other by first spring 34. First magnet 32 ​​is fixedly connected to the other side of insert strip 33. Second magnet 36 is fixedly connected to both sides of fixed box 35. First magnet 32 ​​and second magnet 36 are magnetically connected. Fixed seat 31 is fixedly installed on the inner wall of double gate valve core 2. First magnet 32 ​​is movably inserted into the inside of fixed seat 31.

[0028] The double gate valve core 2 is internally provided with an adjusting component 4, which includes a push rod 41 and a second spring 42.

[0029] The push rod 41 is movably inserted into the inside of the double gate valve core 2. The second spring 42 is wound around the outer surface of the push rod 41. One end of the second spring 42 abuts against the double gate valve core 2, and the other end of the second spring 42 is fixedly connected to the push rod 41. The adjusting component 4 also includes a wedge block 43, a slot 44, and an arc block 45.

[0030] The double gate valve core 2 has a groove 44 inside, an arc-shaped block 45 is fixedly connected inside the groove 44, and a wedge-shaped block 43 is fixedly connected to the end of the push rod 41. The wedge-shaped block 43 abuts against the arc-shaped block 45. Sealing rings 5 ​​are fixedly connected to both sides inside the valve body 1. The outer surface of the sealing rings 5 ​​abuts against the double gate valve core 2. The wedge-shaped block 43 contacts the arc-shaped surface of the arc-shaped block 45 downwards, pushing the double gate valve core 2 open to both sides, so that the double gate valve core 2 abuts against the sealing rings 5, ensuring the sealing effect. The wedge-shaped block 43 does not contact the arc-shaped block 45 upwards. Under the action of the first spring 34, the double gate valve core 2 closes inwards, releasing the sealing effect and meeting the user's needs.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
