Abstract
Provided is an evacuation and winterization system of an upper hose of a vacuum tube solar water heater, mainly comprises a thermos barrel of the vacuum tube solar water heater (1), an auxiliary empting tube (2), an upper hose (3), an auxiliary empting valve (4), a priming valve (5) and the like, as the attached sketch. An end opening of the upper hose (3) is communicated with the indoor through the priming valve (5), an upper port enters into the thermos barrel from the upper side of the thermos barrel (1) out the room, and then being bent downward to the position of 1 centimeter of the lower side. An upper port of the auxiliary empting tube (2) is communicated with an upward crotch on the highest position of the upper hose (3), and the end opening enters into the room and is communicated with the auxiliary empting valve (4). The system can empty the water in the upper hose (3) and prevent frostbite.
Description
The utility model relates to a kind of solar vacuum-tube water heater upper hose winterization system, especially a kind of solar vacuum-tube water heater upper hose evacuation and anti-freezing system, this practical solar water heater field that belongs to.
The general solar vacuum-tube water heater of being made up of antifreeze vacuum solar heat-collecting pipe and antifreeze heat-preserving container itself is antifreeze, and also can the daylighting heat absorption shine hot water in winter; But by the indoor outdoor section that leads to the upper hose of solar vacuum-tube water heater heat-preserving container is not antifreeze, so the phase of freezing in the winter time still can't use.At present, generally be to realize antifreeze purpose at the very thick insulation material of the outdoor subpackage of upper hose.But this method has shortcoming: when water supply pipeline (especially level) long or water supply pipeline through can't construct local time, just be difficult to carry out the heat-preserving anti-freezing construction; Insulation material is very thick, and cost is higher, and temperature is low excessively, still can deep colling when cooling time is long.
The purpose of this utility model is for a kind of solar vacuum-tube water heater upper hose evacuation and anti-freezing system is provided.
The utility model is 1. (to be called for short heat-preserving container 1. by the solar vacuum-tube water heater heat-preserving container, the back with), auxiliary evacuated tube 2., upper hose 3. (also being downcomer simultaneously), auxiliary exhaust-valve 4., priming valve 5., running water pipe 6., tube connector 7., nozzle switch 8., 9. shower nozzle reach tube connector and 10. form, as shown in the figure, it is characterized in that: 6. 5. upper hose end opening 3. be connected with running water pipe through priming valve indoor, suitable for readingly then enter in the heat-preserving container from heat-preserving container top 1. outdoor, bend towards down then, until from about 1 centimeters of bottom; Auxiliary row chamber pipe suitable for reading and upper hose 2. 3. highest point prong up is connected, and 4. end opening then is connected with auxiliary exhaust-valve in the inlet chamber; 3. upper hose has a prong in priming valve top 5., thus prong draw tube connector 7. and successively with nozzle switch 8., 10. tube connector reach shower nozzle and 9. be connected.4. reach nozzle switch 8. when closing auxiliary exhaust-valve, open water supply valve 5., running water just by upper hose 3. enter heat-preserving container 1. in, to protect the bucket 1. fill it up with after, close priming valve 5., open auxiliary exhaust-valve and 4. reach nozzle switch 8., 2. air just enters upper hose highest point 3. by auxiliary exhaust-valve, destroyed the siphonage of upper hose, 7. 3. interior highest point of upper hose and following water just pass through tube connector like this, nozzle switch 8., 10. tube connector reaches shower nozzle and 9. flows out, and the water in the heat-preserving container can not flow out, thereby the water that reaches in the emptying upper hose comes antifreeze purpose, put the washing of heat-preserving container in 1. when bathing when needs, close earlier auxiliary exhaust-valve 4. with nozzle switch 8., open priming valve again and 5. add water in 3. and promptly close priming valve 5. about 5～10 seconds to upper hose, at this moment, open nozzle switch 8., the water of heat-preserving container in 3. will be under siphonage by upper hose 3., tube connector 7., nozzle switch 8., tube connector 10., 9. shower nozzle flows out, but so bathing.
This novel upper hose evacuation and anti-freezing system that the utility model provides, thus can easily the water emptying in the solar vacuum-tube water heater upper hose be reached antifreeze purpose; Antifreeze solar vacuum-tube water heater itself also can be installed and be used easily in the freezed in winter phase of cold, and upper hose need not wrap very thick insulation material, greatly reduce cost.
Accompanying drawing is a system schematic of the present utility model.
Show the part of the solar vacuum-tube water heater that only draws among the figure as accompanying drawing is attached---heat-preserving container profile 1.; When 1. heat-preserving container links up and be installed on the roof with vacuum solar heat-collecting pipe and support, just constituted one and overlapped the solar vacuum-tube water heater bath system that really can install and use easily complete winter.Each part of the utility model all can have been bought or made by oneself.
Claims (1)
1. solar vacuum-tube water heater upper hose evacuation and anti-freezing system, form by solar vacuum-tube water heater heat-preserving container, auxiliary evacuated tube, upper hose, auxiliary exhaust-valve, priming valve, running water pipe, tube connector, nozzle switch, shower nozzle etc., it is characterized in that: the top from heat-preserving container suitable for reading of upper hose enters in the heat-preserving container, bend towards down then, until from about 1 centimeters of bottom, and be connected with priming valve in the end opening inlet chamber of upper hose, auxiliary evacuated tube is connected with upper hose highest point prong up, is connected with auxiliary exhaust-valve in the end opening inlet chamber.
