Heating constant-temperature system for hot water pipeline

Abstract

The invention discloses a heating constant-temperature system for a hot water pipeline, which mainly comprises an intelligent controller 1, a water inlet 2, a water outlet 3, a temperature sensor or a temperature control switch 4, a binding post 5, a heat preservation pipe 7 of the hot water pipeline, a hot water pipeline 8, power leads 6 and 9 of an insulating heating wire, an insulating heating wire 10, tee joints 12 and 14, a power line 11 of the intelligent controller and a ground wire 13. The intelligent controller 1 is mutually connected with the insulating heating wire 10, the temperature sensor or the temperature control switch 4, the binding post 5 and the power leads 6 and 9; and the hot water pipeline 8 is mutually communicated and connected with the tee joints 12 and 14, the water inlet 2 and the water outlet 3 respectively. The temperature sensor or the temperature control switch 4 is arranged at any place of the hot water pipeline 8; the heat preservation pipe 7 is sleeved outside the hot water pipeline 8; and the ground wire 13 is connected with the tee joint 12 or the tee joint 14. The heating constant-temperature system for the hot water pipeline mainly solves the problem that once the hot water stops flowing in the hot water pipeline for a period of time, the temperature of the hot water in the hot water pipeline drops as the temperature-constant effect of the hot water pipeline is unsatisfactory, and particularly in a solar water heater / solar water heating system, the hot water pipeline made of a plastic material can be blocked or even frozen and cracked in the cold weather in the conventional hot water pipeline.

Description

technical field [0001] The purpose of inventing a heating constant temperature system for hot water pipes is mainly to solve the problem of poor constant temperature effect of hot water pipes in existing hot water pipes. The temperature of medium and hot water drops, especially in solar water heaters / systems, hot water pipes made of plastic materials will freeze and block or even freeze hot water pipes in cold weather. Background technique [0002] At present, the heat preservation of hot water pipes mainly includes central heating (hot water supply or heating) with boilers as central heat sources, solar water heaters / system centralized or independent decentralized heating, and so on. Since the hot water in the heating pipe circulates continuously, when the hot water in the hot water pipe passes through the radiator to dissipate heat, the temperature of the water in the pipe will drop, but it will flow back to the boiler in time, and the water temperature will return to norm...
