Embodiment 1

[0014] Embodiment 1 (see figure 1 ):

[0015] exist figure 1 Among them, the installation position of the water storage tank 10 is lower than the installation position of the all-glass vacuum heat collecting tube 4.

[0016] This embodiment includes a water storage tank 10, an all-glass vacuum heat collecting tube 4, a heat collecting coupler 5, a heat collecting circulation pump 1, an automatic controller 8, a water level controller 13 for replenishing water to the water storage tank, and a one-way valve 2; automatic control The output terminal of instrument 8 controls the on-off of the power supply of heat collecting circulation pump 1 and solenoid valve 16 respectively; The output terminal is connected to the corresponding input terminal of the automatic controller 8 .

[0017] The liquid level sensor adopts a special water flow switch 9 whose output is a pulse signal, and the water flow switch 9 is installed on the heat collection and return water circulation pipeline 6...

Embodiment 2

[0021] Embodiment 2 (seeing Fig. 2,3):

[0022] Embodiment 2 differs from Embodiment 1 in that there are two points. The first point is that the installation position of the water storage tank 10 is higher than the installation position of the all-glass vacuum heat collection tube; Check valve 2, but solenoid valve 16. The liquid level sensor adopts a special liquid level sensor 17 whose output signal is a switch signal, and the special liquid level sensor 17 is installed at the highest point position of the heat collection and return water circulation pipeline 6; the output terminal of the special liquid level sensor 17 is connected to The corresponding input terminal of the automatic control instrument 8.

[0023] In this embodiment, when the special liquid level sensor 17 is short of water, the special liquid level sensor 17 outputs a switch signal to the automatic controller 8, and the automatic controller 8 outputs two instruction signals, and one instruction signal goes...

Abstract

The invention relates to a solar hot water system with the function of anti-running water. The solar hot water system comprises a water storage tank, a full glass vacuum heat collecting tube, a heat collecting coupler, a heat collection circulating pump, an automatic controlling instrument, a water level controller for replenishing water for the water storage tank and a one way valve or an electromagnetic valve, wherein the output end of the automatic controlling instrument controls the power on-off of the heat collection circulating pump and the electromagnetic valve respectively. The solar hot water system is characterized in that the solar hot water system also comprises a liquid level sensor which prevents water from running after the full glass vacuum heat collecting tube is damaged; and the output end of the liquid level sensor is connected with the corresponding input end of the automatic controlling instrument. The solar hot water system has the advantages of preventing the problem of water running produced after the full glass vacuum heat collecting tube is unexpectedly damaged, thereby avoiding the waste of mass water resource and ensuring the normal operation of the solar hot water system.

Description

technical field [0001] The invention relates to a solar water heating system with the function of preventing running water. Background technique [0002] Chinese patent discloses "a multi-heat source automatic hot water supply system" (patent application number: 200820076319.2), which includes a water storage tank, an all-glass vacuum heat collecting tube, a heat collecting coupler, a heat collecting circulation pump, an automatic controller, Water level controller, one-way valve or solenoid valve for replenishing water to the water storage tank; the output end of the automatic controller controls the on-off of the power supply of the heat collecting circulating pump and the solenoid valve respectively. In the above-mentioned hot water system, if the all-glass vacuum heat-collecting tube is accidentally damaged, the cold and hot water in the water storage tank and the entire system will run away along the damaged all-glass vacuum heat-collecting tube, resulting in a large am...
