Description

Technical Field

[0001] The utility model relates to the technical field of pipeline locking, in particular to a magnetic pipeline lock valve with a lock cap. Background Technique

[0002] Ordinary valves are difficult to effectively prevent unauthorized operations and malicious damage, resulting in pipeline system leakage, energy waste and safety hazards. The magnetic pipeline lock valve uses the magnetic principle and can only be opened by a specific magnetic key, greatly improving the safety and controllability of the pipeline system. It is widely used in heating, water supply and other fields, ensuring the stable operation of the system and the reasonable allocation of resources.

[0003] The magnetic pipeline lock valve is composed of components such as a valve body, a valve core, a magnetic lock core and a valve stem. Its working principle is based on magnetic interaction. The valve core and the valve stem are connected by the magnetic lock core. Under normal conditions, the magnetic lock core makes the valve core fit tightly with the valve cavity to achieve the closed state and prevent the medium from flowing. When a matching magnetic key approaches the lock core, a magnetic force is generated to unlock the lock core, enabling the valve stem to drive the valve core to move, thereby opening the valve and allowing the medium to pass through. This design ensures that only authorized personnel can operate the valve with a special key, guaranteeing the safety and control of the pipeline system.

[0004] When installing traditional pipelines, several bolts are used for installation, which results in repeated bolt disassembly and assembly during both installation and disassembly of the device, greatly increasing the installation and maintenance costs of the device. Therefore, a magnetic pipeline lock valve with a lock cap is proposed to solve the above problems. Content of the Utility Model

[0005] In order to make up for the above deficiencies, the utility model provides a magnetic pipeline lock valve with a lock cap, aiming to improve the problem that the installation and maintenance time cost of the device is too high due to the large amount of time consumed during the installation and disassembly of the existing device.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme: a magnetic pipeline lock valve with a lock cap, including a valve body, both the left and right sides of the valve body are slidably connected with sliding plates, both the upper and lower ends of the sliding plates are rotatably connected with connecting rods, both the left and right sides of the valve body are fixedly connected with two fixing blocks, and clamping blocks are slidably connected inside multiple fixing blocks. The far ends of the connecting rods are rotatably connected to one side of the clamping blocks. Threaded rods are rotatably connected to both the left and right sides of the valve body, and the threaded rods are threadedly connected inside the sliding plates. One end of the threaded rod is fixedly connected with a knob. Sealing components are arranged on both the left and right sides of the valve body, and the sealing components are used to prevent pipeline medium leakage.

[0007] Further, the sealing assembly includes two wear-resistant layers, which are respectively fixedly connected to the left and right parts of the valve body. A sealing layer is fixedly connected inside the wear-resistant layer, and a support layer is fixedly connected inside the sealing layer.

[0008] Further, a shaft body is rotatably connected inside the valve body, and a turntable abuts against the upper end of the shaft body.

[0009] Further, both the shaft body and the turntable are made of magnets.

[0010] Further, a first chute is provided on both the left and right sides inside the valve body, and the sliding plate and the two connecting rods are both slidably arranged inside the first chute.

[0011] Further, a second chute is provided inside one end of the clamping block, and the fixed block is slidably arranged inside the second chute.

[0012] Further, pipes are threadedly connected to both the left and right sides of the valve body. A plurality of uniformly distributed positioning grooves are provided on the adjacent sides of the pipes, and a plurality of uniformly distributed positioning blocks are fixedly connected to both the left and right sides of the valve body. The positioning blocks are slidably arranged inside the positioning grooves.

[0013] Further, the wear-resistant layer is made of nitrile rubber, the sealing layer is made of fluororubber, and the support layer is made of aluminum alloy.

[0014] The utility model has the following beneficial effects:

[0015] 1. In the utility model, a triangular screwdriver is used to rotate the knob. The knob drives the threaded rod to rotate, and the threaded rod drives the sliding plate to move. While the sliding plates approach each other to push the two connecting rods to move, they also push the two clamping blocks to rotate and cover one side of the pipe. Continuously rotating the knob causes the clamping blocks to be pushed by the two connecting rods to move away from the pipe, so that the two clamping blocks can clamp and abut against the pipe to lock it, thereby realizing the function of quickly installing the valve body.

[0016] 2. In the utility model, in order to ensure the seal between the valve body and the pipe, wear-resistant layers are provided at the contact surfaces between the left and right ends of the valve body and the pipe. The wear-resistant layers can protect the internal structure from physical wear, the sealing layer can prevent the leakage of pipeline media, and the support layer can prevent the outer structure from being deformed by pressure, resulting in the failure of pipeline sealing.

Slide plates 2 are slidably connected to both the left and right sides of the valve body 1. The slide plates 2 can push the connecting rods 3 to move. Connecting rods 3 are rotatably connected to both the upper and lower ends of the slide plates 2. The connecting rods 3 can push the clamping blocks 7 to move. First chutes 8 are provided on both the left and right sides inside the valve body 1. The slide plates 2 and the two connecting rods 3 are all slid inside the first chutes 8. Two fixing blocks 6 are fixedly connected to both the left and right sides of the valve body 1. The fixing blocks 6 can fix the movement fulcrums of the clamping blocks 7. Clamping blocks 7 are slidably connected inside multiple fixing blocks 6. The clamping blocks 7 can assist in completing the installation of the device. A second chute 9 is provided inside one end of the clamping block 7. The fixing blocks 6 slide inside the second chute 9. The far ends of the connecting rods 3 are rotatably connected to one side of the clamping block 7. Threaded rods 4 are rotatably connected to both the left and right sides of the valve body 1. The threaded rods 4 can push the slide plates 2 to move and will form self-locking when the slide plates 2 and the threaded rods 4 are tightened. The threaded rods 4 are threadedly connected inside the slide plates 2. A knob 5 is fixedly connected to one end of the threaded rod 4. The knob 5 can drive the threaded rod 4 to rotate. Sealing components are provided on both the left and right sides of the valve body 1. The sealing components are used to prevent the leakage of the medium in the pipeline 17. A shaft body 15 is rotatably connected inside the valve body 1. The shaft body 15 can control the opening and closing of the valve body 1. The upper end of the shaft body 15 abuts against a turntable 16. The turntable 16 can drive the shaft body 15 to move. Both the shaft body 15 and the turntable 16 are made of magnets. The turntable 16 can be adsorbed on the upper end of the shaft body 15.

[0024] Referring to Figures 1-3 , the sealing component includes two wear-resistant layers 12. The wear-resistant layers 12 can protect the internal structure from physical wear. The wear-resistant layers 12 are made of nitrile rubber. Nitrile rubber has good wear resistance and relatively high elasticity. The two wear-resistant layers 12 are respectively fixedly connected to the left and right parts of the valve body 1. A sealing layer 13 is fixedly connected inside the wear-resistant layer 12. The sealing layer 13 can prevent the leakage of the medium in the pipeline 17. The sealing layer 13 is made of fluororubber. Fluororubber has good sealing performance. A support layer 14 is fixedly connected inside the sealing layer 13. The support layer 14 can prevent the external structure from deforming. The support layer 14 is made of aluminum alloy. Aluminum alloy has good structural strength. Pipelines 17 are threadedly connected to both the left and right sides of the valve body 1. A plurality of uniformly distributed positioning grooves 11 are provided on the adjacent side of the pipelines 17.

The positioning blocks 10 can position the position of the valve body 1 during installation. The positioning blocks 10 slide inside the positioning grooves 11.

[0025] Working principle: Align multiple positioning blocks 10 of the valve body 1 with multiple positioning grooves 11 and insert them. Then use a triangular screwdriver to rotate the knob 5. The knob 5 drives the threaded rod 4 to rotate, and the threaded rod 4 drives the slide plate 2 to move. As the slide plates 2 approach each other, they push two connecting rods 3 to move, and at the same time, they push two clamping blocks 7 to rotate and cover one side of the pipeline 17. Continuously rotate the knob 5 so that the clamping blocks 7 are pushed by the two connecting rods 3 to move away from the pipeline 17. Thus, the two clamping blocks 7 can clamp and abut against the pipeline 17 to lock it. Then stop rotating the knob 5 to form self-locking between the threaded rod 4 and the slide plate 2. In this way, the function of rapid installation of the valve body 1 can be realized. To ensure the seal between the valve body 1 and the pipeline 17, wear-resistant layers 12 are provided on the contact surfaces of the left and right ends of the valve body 1 and the pipeline 17. The wear-resistant layers 12 can protect the internal structure from physical wear. The sealing layer 13 can prevent the leakage of the medium in the pipeline 17. The support layer 14 can prevent the outer structure from being deformed under pressure, resulting in the sealing failure of the pipeline 17.
