Abstract
The utility model discloses a pipe burst warning system for a non-pressure bearing type solar energy water heating system, which comprises a heat collection pipe (1) and a water storage tank (17). The heat collection pipe (1) is communicated with the water storage tank (17) through a water outlet pipe (18). The pipe burst warning system is characterized in that a one-way water flow switch (15) is arranged on the water outlet pipe (18). The one-way water flow switch (15) is connected with a warning device (16) through a signal wire (4). The pipe burst warning system additionally arranges the one-way water flow switch as a water leakage warning signal at the water outlet pipe of the solar energy heat collection pipe, so as to know the burst leakage situation of the solar energy system. The warning manner has the advantages that the initial investment is small, related mature product is available on the market, long-distance centralized monitoring can be realized by accessing to a building control system, and related valves can be closed while warning to avoid loss of water inside the water storage tank.
Description
Technical field
The utility model relates to the solar water water leakage alarm system of plumbing and automatic control engineering application, is used in particular for non-bearing type solar heat-collection hot-water heating system water leakage alarm system.
Background technology
At present, regenerative resources such as solar energy are widely used, and it is more and more universal to utilize solar energy to produce the application of hot water in people life, and government has also put into effect relevant regulations.
Existing solar water heating system mainly is made of solar thermal collection system and storage tank.Described solar thermal collection system is inserted in the storage tank by outlet pipe by an end of many solar energy heat collection pipes, utilizes the principle work that cold water sinks, hot water floats.During use, cold water is put storage tank earlier into, and cold water sinks, pour in the solar energy heat collection pipe that many parallel connections, solar energy heat collection pipe progressively heats up water wherein through solar radiation, and circulates by the cold and hot proportion of water in the storage tank is different, makes whole box water intensification back for people to use.
For the non-bearing type solar water heating system, thermal-collecting tube explosion or ruined situation take place sometimes, cause a large amount of drainages, the hydraulic pressure in the thermal-collecting tube reduces, and the water in the storage tank can flow back to the thermal-collecting tube place along outlet pipe.If untimelyly close related valve and reparation in time can influence normal use, and to a certain extent other thermal-collecting tubes there is in various degree infringement.
The utility model content
Can give the alarm when the leaking non-bearing type solar water heating system booster warning system of signal of the thermal-collecting tube that the technical problems to be solved in the utility model provides a kind of solar energy.
For solving the problems of the technologies described above, the utility model non-bearing type solar water heating system booster warning system comprises thermal-collecting tube, storage tank, and described thermal-collecting tube is connected by outlet pipe with described storage tank, and the unimodal current switch is set on the described outlet pipe.
Preferably, described unimodal current switch links to each other with warning device by holding wire.
Add the unimodal current switch as the water leakage alarm signal at the outlet pipe place of solar energy heat collection pipe, can in time understand the quick-fried leakage situation of solar energy system, the advantage of this type of alarm is: initial cost is little, relevant ripe product is arranged on the market, insert the building control system and can realize that remote centralized monitors, when sending warning, can close related valve, avoid the water loss in the storage tank.

The specific embodiment
Hereinafter with reference to the accompanying drawings the utility model non-bearing type solar water heating system booster warning system is described in detail.
The warning system that the utility model provides a kind of non-bearing type solar water collecting system to leak in a large number comprises heat collector, temp probe 2, pipeline 3, holding wire 4, gate valve 5, check-valves 6, water circulating pump 7, water meter 8, ball-cock assembly 9, water outlet device 10, hutch water device 11, filling pipe 12, blow-off pipe 13, overflow pipe 14, unimodal current switch 15, warning device 16.
One end of the thermal-collecting tube 1 of heat collector is connected with storage tank 17 by outlet pipe 18, and the other end of the thermal-collecting tube 1 of heat collector is connected with gate valve 5, check-valves 6, water circulating pump 7, gate valve 5, storage tank 17 successively by pipeline 3.Temp probe 2 is set in the heat collector, and temp probe 2 links to each other with described water circulating pump 7 by holding wire 4.
The thermal-collecting tube 1 of heat collector is exposed under the sunshine, and along with the lengthening of solar light irradiation time, the cold water in the thermal-collecting tube 1 of heat collector heats up gradually.When the water in the solar energy heat collection pipe 1 reaches design temperature, the temp probe 2 that is arranged in the solar energy heat collection pipe 1 sends signal to water circulating pump 7, water circulating pump 7 work the cold water in the storage tank 17 is extracted in the solar energy heat collection pipe 1, and the hot water in the heat collector will flow in the storage tank 17.Repeat said process, the cold water in the storage tank 17 all circulates and is hot water the most at last, and is for people to use.
The situation of thermal-collecting tube 1 explosion takes place in heat collector in use sometimes, and after thermal-collecting tube 1 explosion, the hydraulic pressure in the thermal-collecting tube 1 reduces, and the water in the storage tank 17 can flow back to thermal-collecting tube 1 place along outlet pipe 18.
Outlet pipe 18 places at thermal-collecting tube 1 are provided with unimodal current switch 15.When reaching setting value, the temperature that detects when temp probe 2 sends signal enabling water circulating pump 7, the cold water of storage tank 17 flows to thermal-collecting tube 1 from storage tank 17 by gate valve 5, water circulating pump 7, check-valves 6, gate valve 5 and pipeline 3, hot water in the thermal-collecting tube 1 flows to storage tank 17 from thermal-collecting tube 1 by outlet pipe 18, at this moment, unimodal current switch 15 is in off-state.
When thermal-collecting tube 1 explosion, when leaking in a large number, hydraulic pressure in the thermal-collecting tube 1 reduces, water flows to thermal-collecting tube 1 from storage tank 17, flow direction in the unimodal current switch 15 place outlet pipes 18 is opposite during with normal circulation, unimodal current switch 15 is opened to warning device 16 and is sent signal at this moment, and warning device 16 sends alarm signal after receiving signal.People will close corresponding valve after hearing alarm signal, avoid the water loss in the storage tank 17.
Above-mentioned design example only is used for the utility model is described, and does not constitute the restriction to the claim scope, and other substantial equivalence means that it may occur to persons skilled in the art that are all in the utility model claim scope.
