Description

Technical Field

[0001] The utility model relates to the technical field of automatic temperature regulating devices, in particular to an automatic temperature regulating control device for a heating pipe network. Background Art

[0002] The heating network refers to the heating pipelines that start from the boiler room, direct-fired machine room, heating center, etc., from the heat source to the thermal entrance of the building. Multiple heating pipelines form a network. At present, most heating networks use manual control when regulating temperature. It is impossible to achieve precise control during the manual control process, which easily causes errors between the temperature and flow rate and the actual requirements, resulting in reduced user experience.

[0003] A Chinese patent discloses an automatic temperature and flow control device for a secondary heating pipe network (application number: 202321493964.5). This solution uses a wrench to twist the connecting cap so that the connecting cap is separated from the connecting seat on the connecting pipe during rotation, so that the regulating box can be quickly replaced and repaired. However, when disassembling, repairing, or connecting the regulating box, external tools such as wrenches are still required, and the operation process is cumbersome and inconvenient. At the same time, the threaded interface at the connection is prone to water leakage. On the other hand, when the No. 1 connecting rod drives the adjustment plate to move, since the No. 1 connecting rod will move out of the inside of the regulating box, water will leak out from the connection between the No. 1 connecting rod and the regulating box, which will cause a waste of resources and cause certain damage to the device, and there is instability.
