Abstract
The utility model relates to a pipeline emptier applicable to a double-pipe solar water heater, which is applicable to solar pipeline freezing protection in winter without additional installation of any pipelines or electric wires at the middle section leading into the outdoor part from the indoor part. The pipeline emptier adopts the basic technical scheme that an auxiliary water tank is additionally added in a position on the original solar water heater cold water pipeline near a water tank, a floating ball is arranged in the water tank and is connected with a switching valve with two inlets and one outlet through a connecting rod device, one ends of two water inlets of the switching valve are connected with a hot water outlet of the water tank of the water heater, the other ends of the two water inlets are directly connected with the atmosphere, and the outlet of the switching valve is led into an indoor hot water faucet. Through changing the sinking and floating state of the floating ball arranged in the auxiliary water tank, the communication state of a hot water pipeline is switched, and the pipeline emptying is realized. A one-way valve is additionally arranged between the added auxiliary water tank and the water tank of the original water heater, so the back flowing of water in the water tank of the solar water heater is prevented.
Description
Affiliated technical field
The utility model relates to the solar water heater field, especially the double hose solar water heater that separates of hot and cold water.
Background technology
As everybody knows, solar water heater temperature is in the winter time crossed when low, and pipeline freezes easily, light blocking pipe then, and influence is used, and is heavy then cause pipeline breaking.Therefore, occurred many means to prevent freezings on the market, it is the surplus water emptying in the outer cold water pipe of solar water heater water tank, the hot-water line that class methods are wherein arranged, and reaches antifreeze purpose.Existing emptying technology has two classes: a class is to lead to outdoor one to two pipeline that installs additional from indoor, the 2nd, install magnetic valve outdoor additional near the solar water heater water tank place, and from indoor to outdoor laying control signal wire.
The distinct disadvantage of existing purging method is: owing to need will inevitably destroy indoor original finishing by indoor to outdoor tubing or electric wire; Sometimes also can be subjected to ambient influnence and can't install pipeline or laying wire additional at all, therefore, limit the popularization of technology.
Summary of the invention
In order to overcome the shortcoming of existing emptying technology, avoid leading to outdoor interlude and installing any pipeline or electric wire additional indoor, I have invented this device.
The basic technical scheme that this device adopts is:
On original solar water heater cold water pipes, install an auxiliary water tank additional near the water tank place, a ball float is housed in the water tank, ball float connects one two by a linkage and advances a transfer valve that outes, two water inlets of this transfer valve, one end connects the hot-water outlet of water-heater water tank, and the other end directly connects atmosphere, and indoor hot water tap is led in the outlet of transfer valve.By the ascending and descending condition conversion of auxiliary water tank inner float ball, change the position of transfer valve, switch the connected state of hot water pipeline, realize tube emptying.
Auxiliary water tank is contained on the cold water pipeline, between auxiliary water tank that installs additional and former water-heater water tank, installs a check valve additional, and water can flow to the water tank of protosun energy water heater from auxiliary water tank, prevents the aqueous reflux in the big sun energy water-heater water tank.
The beneficial effects of the utility model are, can realize the surplus water in drain-solar water heater cold water pipe, the hot-water line, and need be between indoor and outdoors any pipeline of adjunction or electric wire, can not destroy indoor original environment, can not installed additional the influence of environment.
Description of drawings
Accompanying drawing 1 is the novel structure chart of this usefulness:
The specific embodiment
Pipeline in the accompanying drawing 1 between auxiliary water tank and two dotted lines is the part that needs to realize the surplus water of emptying.
1 auxiliary water tank is contained in outdoor near protosun energy water-heater water tank place, 2 ball floats are housed in the auxiliary water tank, the skin valve is arranged on 2 ball floats, during normal the use, open indoor 12 inlet valves that are connected on the running water, close 13 bathroom hot and cold water taps, this moment, cold water entered auxiliary water tank by the cold water pipe of 11 indoor pass-outs, enter water-heater water tank by 4 check valves, finish hydrodynamic(al) and do.Under buoyancy function, 2 ball floats, 6 connecting rods that rise drive 7 transfer valves actions, and 10 lead to indoor hot-water line and 9 connects the connection of solar water heater hot water outlet, can normally use hot water.
When the needs emptying pipe, close 12 inlet valves, 13 bathroom hot and cold water taps are got to cold water side, this moment, the water of the cold water pipe of 1 auxiliary water tank and 11 indoor pass-outs flowed out from pipeline, enters bathtub owing to the gravity effect.Because water level descends, and 2 ball floats sink, 6 connecting rods drive the action of 7 transfer valves simultaneously, change state, 8 air inlet pipe and 10 lead to indoor hot-water line to be connected, and opens indoor 13 bathroom hot and cold water taps this moment, air enters 10 and leads to indoor hot-water line, and Guan Zhongyu water is drained.
Claims (2)
1. pipeline exhausting device that is applicable to the double hose solar water heater, it is characterized in that: on original solar water heater cold water pipes, install an auxiliary water tank additional near the water tank place, a ball float is housed in the water tank, ball float connects one two by a linkage and advances a transfer valve that outes, two water inlets of this transfer valve, and an end connects the hot-water outlet of water-heater water tank, the other end directly connects atmosphere, and indoor hot water tap is led in the outlet of transfer valve.
2. double hose solar energy water heater pipe emptier according to claim 1 is characterized in that: auxiliary water tank is contained on the cold water pipeline, and check valve is housed on the auxiliary water tank, and water can flow to the water tank of protosun energy water heater from auxiliary water tank.
