Description

Technical Field

[0001] This utility model relates to the field of heat meter technology, and more specifically to a heat meter that is easy to assemble and disassemble. Background Technology

[0002] A heat meter is an instrument used to measure and calculate the heat consumed in a building's heating or air conditioning system. It accurately measures the actual heat used by the user, providing a basis for charging based on heat consumption (i.e., "individual metering, charge based on usage"), and helps promote energy conservation and emission reduction. Its principle involves a flow meter emitting a pulse signal proportional to the flow rate, a pair of temperature sensors providing analog signals indicating temperature levels, and then using a calculation formula to calculate the heat received by the heat exchange system based on the collected signals.

[0003] For example, a heat meter with prior art disclosure number CN220708593U uses a positioning ring and an alignment ring to locate the position of the heat meter body and the pipe during installation, thereby assisting the installer.

[0004] However, the existing technology described above still has the following problems in use: because the gas contains a small amount of impurities, these impurities adhere to the surface of the heat meter's detection head, affecting the accuracy of heat detection; and the detection head on traditional heat meters is inconvenient to disassemble. Based on this, this utility model provides a heat meter that is easy to assemble and disassemble. Utility Model Content

[0005] To overcome the aforementioned deficiencies of the prior art, this utility model provides a heat meter that is easy to assemble and disassemble. By providing a detection tube at the front end of the main body, a detection head is placed to perform heat detection. The detection data can be displayed on the control panel, which is convenient for staff to check at any time. After long-term use, staff only need to loosen several second bolts to pull the detection head out of the detection tube for maintenance or replacement. At the same time, the control panel can be disassembled and replaced by loosening the spring pin, thus solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a heat meter that is easy to assemble and disassemble, comprising a main body, with an inlet pipe and an outlet pipe respectively provided at both ends of the main body, a detection tube fixedly passing through the front end of the main body, a detection head passing through the inside of the detection tube, the detection head extending into the interior of the main body, the detection head being connected to the main body via an electric wire, a first rubber sealing ring fixedly provided at the front end and inner wall of the detection tube, the first rubber sealing ring contacting the outer wall of the detection head, an installation groove provided at the top of the main body, a control panel provided inside the installation groove, spring pins fixedly passing through the front and rear sides of the main body, slots provided on the front and rear sides of the control panel, the spring pins being inserted into the slots.
