Description
Technical Field
[0001] This utility model relates to the field of electromagnetic valve pipeline technology, specifically an electromagnetic valve pipeline heater. Background Technology
[0002] Solenoid valves are basic components for automatic flow control. They control the position of the valve core through an electromagnetic coil, cutting off or connecting the air source to change the direction of fluid flow, thereby controlling the flow of the medium and realizing the control of valve opening and closing. They are usually composed of valve body, electromagnetic coil, valve core (or iron core, armature), spring and other parts.
[0003] Regarding the above-mentioned and existing related technologies, the inventor believes that the following defects often exist: In the construction of automated hump yards for railways, many pipelines need to be equipped with solenoid valves. Since some solenoid valves are used in low-temperature environments, a heat source is needed to heat the pipelines. Due to the outdated and energy-intensive components of traditional heaters, they have low thermal efficiency and are prone to large heat loss during use. Therefore, an solenoid valve pipeline heater is proposed to address the above problems. Utility Model Content

A controller is fixedly connected to the upper surface of the power cord. A temperature sensor is fixedly connected to the inner surface of the pipeline. A data cable is fixedly connected to the surface of the temperature sensor and the bottom end of the controller. The electric heating tape is wrapped around the surface of the pipeline, and the temperature sensor is fixed to the inner surface of the pipeline. Then, the controller on the power cord and data cable is plugged into a power strip. By setting the electric heating tape, the pipeline can be heated, reducing the possibility of pipeline icing.
[0006] Preferably, the surface of the pipe is provided with a heat insulation device, which includes a main cover and a secondary cover. The main cover and the secondary cover are fitted over the surface of the pipe and the heating tape. Two placement blocks are fitted over the surface of the pipe. The two placement blocks are located on both sides of the main cover. Two insertion blocks are slidably connected to the inner wall of the placement blocks. The two insertion blocks are respectively inserted into the inner wall of the main cover and the secondary cover. The placement blocks are fitted over the surface of the main cover and the secondary cover, and then the two insertion blocks are pushed to insert into the inner wall of the main cover and the secondary cover respectively. By setting the main cover and the secondary cover, the heat insulation effect can be increased.
[0007] Preferably, a limiting disk is fixedly connected to the side wall of the insertion block. The limiting disk is located on the inner surface of the placement block. When the insertion block moves, the insertion block drives the limiting disk to slide, and the limiting disk restricts the position of the insertion block within the placement block.
[0008] Preferably, a first spring is fixedly connected to the side wall of the limiting plate and the inner surface of the placement block, and a pull block is fixedly connected to the surface of the limiting plate. When the pull block is released, the first spring will drive the limiting plate and the pull block to move. By setting the first spring, the limiting plate can be driven to slide, and the position of the limiting plate can also be restricted.
[0009] Preferably, limiting blocks are fixedly connected to both sides of the pull block, and the inner surface of the limiting block is slidably connected to the surface of the placement block. The limiting block slides on the surface of the placement block and can restrict the position of the pull block within the placement block.
[0010] Preferably, the surface of the placement block is provided with a groove, and the inner wall of the groove of the placement block is slidably connected to the surface of the pull block. When the pull block moves, the pull block will slide on the inner wall of the groove. The opening of the groove can facilitate the sliding of the pull block on the inner wall of the placement block.

The locking block is inserted into the inner surface of the storage block and the inner wall of the strap. By setting the strap, the storage block and the locking block, the gap between the main cover and the secondary cover can be reduced.
[0012] Preferably, two second springs are fixedly connected to the side wall of the card block and the inner surface of the storage block, and top plates are fixedly connected to both sides of the card block.

[0013] The advantages of this utility model are:
[0014] 1. In the construction of an automated hump wind system, this utility model requires heating the pipeline used by the solenoid valve. After the pipeline is installed, the heating tape is wrapped around the surface of the pipeline, and then the temperature sensor is fixed to the pipeline. The controller on the power cord and data cable is then plugged into a power strip. When the heating tape is in use, it heats the pipeline, and the temperature sensor monitors the pipeline temperature. By setting up the entire device, the pipeline can be heated, reducing the large heat loss that occurs with traditional heaters.

[0025] 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 scope of protection of the present utility model.
[0026] Please see Figure 1-6 As shown, an electromagnetic valve pipeline heater includes a pipeline 1 and an electric heating tape 2. The electric heating tape 2 is wound around the surface of the pipeline 1. A power cord 3 is fixedly connected to the surface of the electric heating tape 2. A controller 4 is fixedly connected to the upper surface of the power cord 3. A temperature sensor 5 is fixedly connected to the inner surface of the pipeline 1. A data cable 6 is fixedly connected to the surface of the temperature sensor 5 and the bottom end of the controller 4. In operation, the electric heating tape 2 is wound around the surface of the pipeline 1, and the temperature sensor 5 is fixed to the inner surface of the pipeline 1. Then, the controller 4 on the power cord 3 and the data cable 6 is plugged into a power strip. By setting the electric heating tape 2, the pipeline 1 can be heated, reducing the possibility of the pipeline 1 freezing.
[0027] The surface of the pipe 1 is provided with a heat insulation device 7, which includes a main cover 71 and a secondary cover 72. The main cover 71 and the secondary cover 72 are fitted onto the surface of the pipe 1 and the heating tape 2. Two placement blocks 73 are fitted onto the surface of the pipe 1, and the two placement blocks 73 are respectively located on both sides of the main cover 71. Two insertion blocks 74 are slidably connected to the inner wall of the placement blocks 73, and the two insertion blocks 74 are respectively inserted into the inner wall of the main cover 71 and the secondary cover 72. During operation, the main cover 71 and the secondary cover 72 are pushed to fit onto the surface of the pipe 1 and the heating tape 2. Then, the placement blocks 73 are fitted onto the surface of the main cover 71 and the secondary cover 72. Then, the two insertion blocks 74 are pushed to insert into the inner wall of the main cover 71 and the secondary cover 72 respectively. By setting the main cover 71 and the secondary cover 72, the heat insulation effect can be increased.
[0028] The side wall of the insertion block 74 is fixedly connected to a limiting disk 75, which is located on the inner surface of the placement block 73. During operation, the insertion block 74 drives the limiting disk 75 to slide, and the limiting disk 75 restricts the position of the insertion block 74 within the placement block 73.
[0029] A first spring 76 is fixedly connected to the side wall of the limiting disk 75 and the inner surface of the placement block 73, and a pull block 77 is fixedly connected to the surface of the limiting disk 75. During operation, pulling the pull block 77 causes the limiting disk 75 to move, and the limiting disk 75 causes the first spring 76 to retract. When using the limiting disk 75, releasing the pull block 77 will cause the first spring 76 to drive the limiting disk 75 and the pull block 77 to move. By setting the first spring 76, the limiting disk 75 can be driven to slide, and the position of the limiting disk 75 can also be restricted.
[0030] Both sides of the pull block 77 are fixedly connected to limit blocks 78, and the inner surface of the limit block 78 is slidably connected to the surface of the placement block 73. During operation, the pull block 77 will drive the limit block 78 to slide, and the limit block 78 slides on the surface of the placement block 73. The limit block 78 can restrict the position of the pull block 77 within the placement block 73.
[0031] The surface of the placement block 73 is provided with a groove 79, and the inner wall of the groove 79 of the placement block 73 is slidably connected to the surface of the pull block 77. During operation, the pull block 77 will slide on the inner wall of the groove 79. The opening of the groove 79 facilitates the sliding of the pull block 77 on the inner wall of the placement block 73.
[0032] The surfaces of the main cover 71 and the secondary cover 72 are provided with fixing devices 8. The fixing devices 8 include straps 81, which are fitted onto the surfaces of the main cover 71 and the secondary cover 72. A storage block 82 is fitted onto the surface of the straps 81, and multiple slots are formed on the surface of the straps 81. A locking block 83 is inserted into the inner wall of the storage block 82 and the inner surface of the slots of the straps 81. During operation, the straps 81 are fitted onto the surfaces of the main cover 71 and the secondary cover 72, and then the storage block 82 is fitted onto the surface of the straps 81. Then, the locking block 83 is pushed to slide on the inner wall of the storage block 82. The locking block 83 is inserted into the inner surface of the storage block 82 and the inner wall of the straps 81. By setting the straps 81, the storage block 82 and the locking block 83, the gap between the main cover 71 and the secondary cover 72 can be reduced.
[0033] Two second springs 84 are fixedly connected to the side wall of the locking block 83 and the inner surface of the storage block 82. Top plates 85 are fixedly connected to both sides of the locking block 83. When working, the top plate 85 is pinched to move the locking block 83. The locking block 83 causes the second springs 84 to retract. When using the locking block 83, the top plate 85 is released and the second springs 84 drive the locking block 83 to move. At the same time, the second springs 84 also restrict the position of the locking block 83.
[0034] Working principle: During the construction of an automated hump wind system, the pipe 1 used by the solenoid valve needs to be heated. After the pipe 1 is set up, the heating tape 2 is wrapped around the surface of the pipe 1, and then the temperature sensor 5 is fixed to the pipe 1. Then, the controller 4 on the power cord 3 and data cable 6 is plugged into the power strip. When the heating tape 2 is in use, it heats the pipe 1, and the temperature sensor 5 monitors the temperature of the pipe 1. By setting up the entire device, the pipe 1 can be heated, reducing the large heat loss that occurs with traditional heaters. At the same time, the temperature inside the pipe 1 can be detected, which facilitates the controller 4 to control the heating tape 2, thereby reducing the possibility of icing in the pipe 1. After the heating tape 2 is wrapped, the main cover 71 and the auxiliary cover 72 are pushed so that they fit over the surface of the pipe 1 and the heating tape 2. Then, the two pull blocks 77 are pulled so that the pull blocks 77 drive the limit plate 75 and the limit block 78 to slide. The limit block 78 slides on the surface of the placement block 73, and the pull block 77 slides on the inner wall of the slide groove 79. When the limit plate 75 slides, it drives the insertion block 7. 4. Sliding, simultaneously the limiting plate 75 will also drive the first spring 76 to retract, and then the placement block 73 will be placed on the surface of the main cover 71 and the secondary cover 72. Releasing the pull block 77 will cause the first spring 76 to rebound, driving the limiting plate 75 and the insertion block 74 to slide. The insertion block 74 will insert into the inner surface of the placement block 73 and the main cover 71. By setting the entire device, a sealed space can be provided, thereby achieving a heat preservation effect and further reducing heat loss. After the main cover 71 and the secondary cover 72 are installed, the strap 81 is placed on the main cover 71. The top plate 85 is then pinched and pushed to move, causing the top plate 85 to slide. The top plate 85 then causes the locking block 83 to slide, and the locking block 83 causes the second spring 84 to retract. The storage block 82 is then placed on the surface of the strap 81. The top plate 85 is then released, and the second spring 84 drives the locking block 83 to slide. The locking block 83 is inserted into the inner surface of the storage block 82 and the inner surface of the slot of the strap 81. By setting the entire device, the gap between the main cover 71 and the secondary cover 72 can be reduced, and the position between the main cover 71 and the secondary cover 72 can also be restricted.
