Description

Technical Field

[0001] This utility model relates to the field of heating anti-theft equipment, specifically a valve body channel internal locking device. Background Technology

[0002] Centralized heating in communities is a common heating method. 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 can directly lead 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. However, some residents still use tools to open the valves themselves, disrupting the community heating system.

[0003] To address the aforementioned issues, a valve body internal locking device is designed to ensure that residents cannot disassemble the valve body internal lock using conventional tools, thereby preventing heat theft within the community and protecting the heating interests of other residents. Utility Model Content

[0004] The purpose of this utility model is to provide a valve body channel internal locking device that ensures that residents cannot disassemble the valve body internal lock using conventional tools, thereby preventing theft of heat within the community and protecting the heating interests of other residents.

[0005] To achieve the above objectives, this utility model employs the following technical solution:

[0006] A valve body channel internal locking device 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; 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, and a flow-blocking end is provided at the mating position. When the flow-blocking end engages with the mating position, it obstructs the connection between the two sides of the valve body.

[0007] 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.

[0008] The flow-blocking part is threaded and fitted with a sleeve, and the mating position mates with the threaded sleeve. When the mating position mates with the threaded sleeve, it obstructs the connection between the two sides of the valve body.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] Because traditional community heating valves are relatively easy to operate, many residents tend to adjust or open them without authorization. This device, however, is designed with a flow-stopping pipe installed in conjunction with the valve body, and a flow-stopping end cap installed along with the pipe. This end cap directly connects to both ends of the valve body for flow control. Due to the unique structure of the flow-stopping end cap, it cannot be disassembled by residents using conventional tools, making it easier for staff to control. Attached Figure Description

[0017] 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.

[0018] A valve body channel internal locking device includes a valve body 1 and a flow-blocking pipe 2. The flow-blocking pipe 2 is disposed on the outer side of the valve body 1 and is connected to the valve body 1. The flow-blocking pipe 2 and the pipes on both sides of the valve body 1 are arranged to cross each other to form a mating position 3 for connecting the flow-blocking pipe 2 and the two ends of the valve body 1. A flow-blocking end 4 is provided at the mating position 3. When the flow-blocking end 4 is engaged with the mating position 3, the connection between the two sides of the valve body 1 is blocked.

[0019] In this configuration, a flow-blocking pipe 2 is installed in conjunction with the valve body 1 to achieve communication between the two sides of the valve body 1. Simultaneously, a flow-blocking end 4 is installed within the flow-blocking pipe 2 to block communication between the two sides of the valve body 1, thus preventing further communication. Specifically, the flow-blocking pipe 2 intersects with the pipes on both sides of the valve body 1, forming a mating position 3 for connecting the flow-blocking pipe 2 and the two ends of the valve body 1. When the flow-blocking end 4 engages with the mating position 3, it obstructs the communication between the two sides of the valve body 1. (See attached diagram). 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 3 formed by the flow-stopping end 4 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 4 cooperates with the cooperation position 3 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 4.

[0020] Because the design of the throttling end 4 needs to ensure that it cannot be easily disassembled, that is, the fit between the throttling end 4 and the mating part 3 cannot be disassembled using conventional tools, the specific structural design of the throttling end 4 is as follows:

[0021] The intercepting end 4 includes an intercepting 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 and blocks the maximum circumference 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, thereby blocking the maximum radius of the nut end 7. If a resident wants to disassemble the intercepting end 4 privately, they need to use tools to clamp the nut end 7 in the relatively narrow space of the intercepting pipe 2, using the blocking member 8, and apply sufficient force to the nut end 7 to achieve the disassembly operation. This is impractical with traditional tools.

[0022] Therefore, the installation of an internal locking device in the valve body channel can ensure that residents cannot disassemble the internal lock of the valve body 1 using conventional tools, thereby avoiding the problem of heat theft within the community and protecting the heating interests of other residents in the community.
