Abstract
The utility model discloses a solar pipeline emptying system, which is suitable for a solar hot water supply system. In order to overcome the defect that normal use of water is influenced since a water supply pipeline in the conventional solar water heating system freezes easily in winter, the utility model provides the solar pipeline emptying system. Water in the solar water supply pipeline is emptied automatically according to the characteristics of the pipeline emptying system, so that freezing of the pipeline is prevented, and the solar pipeline emptying system has the characteristics of simple structure, reliability in working, low price and no need of a power supply. The solar pipeline emptying system is implemented in a way that a water supply pipeline at the lower end of a water tank is connected with the water inlet end of a pressure-difference opening one-way valve and the water outlet end of a one-way valve; the water inlet end of the pressure-difference opening one-way valve and the water outlet end of the one-way valve are connected with the water supply pipeline; the upper end of the water supply pipeline is connected with an emptying air inlet valve; the other end of the emptying air inlet valve is connected with the upper part of the water tank; a water using valve, a pipeline emptying valve and a water feeding valve are arranged at the lower end of the water supply pipeline respectively; the other end of the water using valve is connected with the water using end of a user; the other end of the water feeding valve is connected with tap water; the other end of the pipeline emptying valve is connected with a sewer pipe.
Description
Technical field
oneplant solar energy pipeline emptying system, be applicable to solar energy hot water supplying system, belong to plumbing equipment manufacturing technology field.
Background technology
Raising along with people's environmental consciousness, the product of energy-saving and environment friendly is popularized, renewable resource is widely used, solar energy has been widely applied to resident family as regenerative resource, particularly solar water heater has spread to every family, for resident provides the hot water of cheap environmental protection.In the use of solar water heater, also some problems have been there are, solar water heater easily produces the phenomenon that supply channel freezes in using winter, affected the use of solar water heater, in order to solve the phenomenon that winter, pipeline froze, what have has installed electric heating heating tape on supply channel, utilize electric heating to overcome the phenomenon of freezing of supply channel, although use electric heating heating tape to overcome the phenomenon that supply channel freezes, but consume a large amount of electric energy, in order to overcome above-mentioned drawback, the invention provides a kind of solar energy pipeline emptying system, can replace the icing phenomenon of utilizing electric heating to overcome supply channel, realize the antifreeze of solar water supply pipeline, thereby guarantee supplying hot water reliably in solar water heater winter, solar energy pipeline emptying system provided by the invention, have simple in structure, reliable operation, cheap, feature without power supply.
Summary of the invention
The purpose of this utility model: easily freeze the drawback that cannot use in order to overcome the supply channel in household solar energy water heater winter, the utility model provides a kind of solar energy pipeline emptying system, utilize the feature of pipeline evacuation system to realize automatically that the water of solar water supply pipeline is emptying, prevented that pipeline from freezing, have simple in structure, reliable operation, cheap, without the feature of power supply.
The utility model solves the technical scheme that its technical problem adopts: solar water supply system is mainly by valve, pipeline and water tank form, it is characterized in that: the supply channel of water tank lower end connects the water intake end of pressure reduction open check valve and the water side of check valve, being connected with supply channel of the water intake end of pressure reduction open check valve and the water side of check valve, in the upper end of supply channel, connect emptying intake valve, the other end of emptying intake valve is connected with the top of water tank, be equipped with respectively with water valve the lower end of supply channel, pipe line evacuation valve and water supply valve, the water end (W.E.) of using that connects user with the other end of water valve, the other end of water supply valve connects running water, the other end of pipe line evacuation valve connects sewer pipe.
The starting differential pressure of pressure reduction open check valve is >5kPa, valve opening when the water inlet end of pressure reduction open check valve is greater than water side 5kPa, valve closing during >5kPa.
Pipe line evacuation valve be flow control valve, the PVS value of pipe line evacuation valve is between 0.06 ~ 0.2.
Emptying intake valve is low discharge differential pressure control valve, and the PVS value of emptying intake valve is between 0.01 ~ 0.05, and when emptying intake valve pressure reduction is greater than 10kPa, emptying intake valve cuts out automatically.
While needing in the winter time the water in emptying solar energy pipeline, as long as pipe line evacuation valve is opened, whole pipeline will automatic-discharging, during bathing, pipe line evacuation valve and water supply valve door are closed, during upper water by pipe line evacuation valve and bathing valve closing.
The beneficial effects of the utility model are: the water in can automatic-discharging solar energy pipeline, prevent solar energy pipeline freezing in the winter time, and guarantee that solar energy is used reliably.
