Description

Technical Field

[0001] This utility model relates to the field of heating equipment, specifically an anti-theft heating device for valve bodies. Background Technology

[0002] Centralized heating is a very common method of winter heating. Typically, heating companies supply heat to communities through pipelines to meet their winter heating needs. Because the heat source is centralized, some residents may not require it for personal reasons. Therefore, during the heat supply process, it's not necessary to connect these residents' pipelines, thus protecting the interests of the heating company while meeting the needs of residents who require heating.

[0003] Some residents, while not paying heating fees, illegally open the heat source pipes connected to their homes, thus illegally supplying heat. This causes significant losses to the heating company and directly leads to insufficient heating in some areas of the community, affecting both the heating company and other residents. Currently, heating staff use bolts to secure the valves of residents not supplying heat during inspections, but some residents still use tools to open the valves themselves, causing disruptions to the community's heating system.

[0004] Based on the above problems, an anti-theft heat device is installed for the valve body to ensure the stability of community heating after it is applied to the heat pipes entering the house. This prevents residents from privately adjusting the supply of heat source in the pipes and avoids theft of heat, thus protecting the effective supply of heat source in the community and the interests of the heating company. Utility Model Content

[0005] The purpose of this utility model is to provide an anti-theft heat device for valve bodies, which can ensure the stability of community heating after being applied to the heat pipes entering the house, that is, to prevent residents from privately adjusting the supply of heat source in the pipes, and to prevent theft of heat, so as to protect the effective supply of heat source in the community and the interests of the heating unit.

[0006] To achieve the above objectives, this utility model employs the following technical solution:

[0007] An anti-theft heat device for a valve body includes a valve body and a flow-blocking pipe. The flow-blocking pipe is disposed on the outer side of the valve body and is connected to the valve body. A flow-blocking end is fitted at the inner end of the flow-blocking pipe. When the flow-blocking end is fixed at the inner end of the flow-blocking pipe, the flow-blocking end obstructs the connection between the two ends of the valve body, thus blocking the flow of the valve body. The flow-blocking pipe and the pipes on both sides of the valve body are intersected to form a mating position for connecting the flow-blocking pipe and the two ends of the valve body. When the flow-blocking end engages with the mating position, the connection between the two sides of the valve body is obstructed.

[0008] The flow-cutting end includes a flow-cutting part and a disassembly part; the disassembly part includes a nut end and a blocking member, the blocking member being disposed on the outer side of the nut end to block the maximum circumferential radius of the nut; a snap-fit ​​fitting is provided with the nut end, the snap-fit ​​fitting passing through the blocking member and fitting against the nut end.

[0009] The snap-fit ​​component includes a gripping link and a snap-fit ​​sleeve; the gripping link is located below the snap-fit ​​sleeve; two arc-shaped sleeve plates are combined to form the snap-fit ​​sleeve, and a fitting gap is left between the two arc-shaped sleeve plates; a blocking protrusion and a nut snap-fit ​​position are provided at the upper end of each arc-shaped sleeve plate, and the blocking protrusion is located outside the nut snap-fit ​​position.

[0010] When the gripping link is pressed toward the throttling end, the two arc-shaped sleeves elastically deform to both sides, causing the blocking protrusion to pass through the blocking member on the throttling end and causing the nut end to fall into the nut locking position.

[0011] A limiting sleeve is slidably provided on the outer side of the snap-fit ​​sleeve, and the upper circumferential dimension of the snap-fit ​​sleeve is larger than the lower circumferential dimension; when the limiting sleeve slides to the upper position of the snap-fit ​​sleeve, the gap between the two arc-shaped sleeve plates is reduced by the limiting sleeve, thereby limiting the distance between the two arc-shaped sleeve plates.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] Because traditional community heating valves are relatively easy to operate, many residents tend to adjust or open / close them without authorization.

[0014] This device is designed with a valve body and a corresponding flow-stopping pipe. The flow-stopping pipe, in turn, is equipped with a flow-stopping end. This end directly connects to both ends of the valve body for flow control. Due to the unique structure of the flow-stopping end, it cannot be disassembled by ordinary users using conventional tools, making it easier for staff to control. Furthermore, to facilitate disassembly, the device includes a snap-fit ​​fitting. This fitting allows for easy removal of the flow-stopping end from its mating position, preventing issues caused by unconventional installation methods that hinder disassembly.

[0022] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined in this application.

[0023] An anti-theft heat device for a valve body includes a valve body 1 and a shut-off pipe 2. The shut-off pipe 2 is positioned on the outer side of the valve body 1 and is connected to the valve body 1. A shut-off end 3 is fitted at the inner end of the shut-off pipe 2. When the shut-off end 3 is fixed at the inner end of the shut-off pipe 2, it obstructs the connection between the two ends of the valve body 1, thus shutting off the flow. In this configuration, the shut-off pipe 2, in conjunction with the valve body 1, enables communication between the two sides of the valve body 1. Simultaneously, the shut-off end 3 within the shut-off pipe 2 blocks communication between the two sides of the valve body 1, thereby preventing further communication. Specifically, the shut-off pipe 2 and the pipes on both sides of the valve body 1 are arranged in a cross configuration, forming a mating position 4 for connecting the shut-off pipe 2 and the two ends of the valve body 1. When the shut-off end 3 engages with the mating position 4, it obstructs the communication between the two sides of the valve body 1. (See attached drawings). Figure 3 As shown, after the flow-stopping pipe 2 is set up to cross and cooperate with the pipes on both sides of the valve body 1, the fluid at one end of the valve body 1 needs to pass through the cooperation position 4 formed by the flow-stopping end 3 and the valve body 1 before flowing out from the other end of the valve body 1. Therefore, after the above structure is set up, the flow-stopping end 3 cooperates with the cooperation position 4 to block the flow of fluid on both sides of the valve body 1, thereby providing the staff with more space for disassembling and installing the flow-stopping end 3.

[0024] Because the design of the throttling end 3 needs to ensure that it cannot be easily disassembled, that is, the fit between the throttling end 3 and the mating part 4 cannot be disassembled using conventional tools, the specific structural design of the throttling end 3 is as follows:

[0025] The flow-stopping end 3 includes a flow-stopping part 5 and a disassembly part 6. The disassembly part 6 includes a nut end 7 and a blocking member 8. The blocking member 8 is located on the outside of the nut end 7, blocking the maximum circumferential radius of the nut. A snap-fit ​​fitting is provided with the nut end 7, which passes through the blocking member 8 and fits against the nut end 7. The blocking member 8 is located on the outside of the nut end 7, thus blocking the maximum radius of the nut end 7. If a resident wants to disassemble the flow-stopping end 3 privately, they need to use tools to clamp the nut end 7 within the relatively narrow space of the flow-stopping pipe 2, using the blocking member 8 to apply sufficient force to achieve the disassembly. This is impractical with traditional tools. Since the installation and disassembly of the flow-stopping end 3 cannot be achieved with conventional tools, a specific structural design for the snap-fit ​​fitting is needed to address this issue.

[0026] The snap-fit ​​component includes a gripping link 9 and a snap-fit ​​sleeve 10; the gripping link 9 is located below the snap-fit ​​sleeve 10; two arc-shaped sleeve plates are combined to form the snap-fit ​​sleeve 10, and a fitting gap 11 is left between the two arc-shaped sleeve plates; a blocking protrusion 12 and a nut snap-fit ​​position 13 are provided at the upper end of each arc-shaped sleeve plate, and the blocking protrusion 12 is located on the outside of the nut snap-fit ​​position 13; when the gripping link 9 is pressed toward the throttling end 3, the two arc-shaped sleeve plates undergo elastic deformation toward both sides, causing the blocking protrusion 12 to pass through the blocking member 8 on the throttling end 3, and causing the nut end 7 to fall into the nut snap-fit ​​position 13. Because traditional disassembly tools cannot easily reach into the intercepting pipe 2 and effectively clamp and disassemble the nut end 7, the snap-fit ​​sleeve 10 is configured with two arc-shaped sleeves. A blocking protrusion 12 and a nut snap-fit ​​position 13 are set at the upper end of the arc-shaped sleeves. The snap-fit ​​sleeve 10 is made of metal, meaning that when a force is applied to the snap-fit ​​sleeve 10 towards the blocking member 8, the blocking protrusion 12 passes through the blocking member 8, causing the nut to snap into place and engage with the nut end 7. In this case, the snap-fit ​​sleeve 10 can be rotated, and the intercepting end 3 can be removed from the engagement position 4 under the action of the force. Most importantly, the snap-fit ​​sleeve 10 is configured with two arc-shaped sleeves because two issues need to be considered: first, ensuring that the blocking protrusion 12 can pass smoothly through the blocking member 8; second, ensuring that the nut snap-fit ​​position 13 can effectively engage with the nut end 7. Therefore, after setting the two curved sleeves, the fitting gap 11 between the curved sleeves can provide space for the shielding protrusion 12 to pass smoothly through the shielding member 8.

[0027] To ensure that the nut locking position 13 can effectively engage with the nut end 7, a limiting sleeve 14 is slidably provided on the outer side of the locking sleeve 10, and the upper circumference of the locking sleeve 10 is larger than the lower circumference. When the limiting sleeve 14 slides to the upper position of the locking sleeve 10, it reduces the gap between the two arc-shaped sleeve plates, limiting the distance between them. That is, after setting the limiting sleeve 14, the upper positions of the two arc-shaped sleeve plates can be locked and limited, allowing the nut locking position 13 to effectively engage with the nut end 7. This ensures that the flow-stopping end 3 can be stably removed from the mating position 4 when the locking sleeve 10 rotates. After removing the flow-stopping end 3, the limiting sleeve 14 can slide down to reduce the distance between the upper positions of the two arc-shaped sleeve plates, making it easier for workers to remove the flow-stopping end 3 from the upper positions of the two arc-shaped sleeve plates.

[0028] Therefore, the installation of an anti-theft heat device for the valve body can ensure the stability of community heating after it is applied to the heat pipes entering the house. This prevents residents from privately adjusting the supply of heat source in the pipes and avoids the problem of heat theft, thus protecting the effective supply of heat source in the community and the interests of the heating unit.
