Abstract
A solar pipeline emptying system is suitable for a solar hot water supply system. A water supply pipeline frozen phenomenon is prone to happening to a current solar water heating system, normal use for a user is influenced, and the solar pipeline emptying system is provided to overcome the defect. The water of a solar water supply pipeline is automatically emptied through the characteristics of the pipeline emptying system, the pipeline is prevented from being frozen, and the solar pipeline emptying system has the advantages of being simple in structure, reliable in work, low in cost and free of a power supply. According to the implementation mode of the system, the water inlet end of a differential pressure opening check valve and the water outlet end of a check valve are connected on the water supply pipeline at the lower end of a water tank, the water inlet end of the differential pressure opening check valve and the water outlet end of the check valve are connected with the water supply pipeline, an emptying air inlet valve is connected at the upper end of the water supply pipeline, the other end of the emptying air inlet valve is connected with the upper portion of the water tank, the lower end of the water supply pipeline is respectively provided with a water valve, a pipeline emptying valve and a water feed valve, the other end of the water valve is connected with the water end of the user, the other end of the water feed valve is connected with tap water, and the other end of the pipeline emptying valve is connected with a sewer pipeline.
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
Object of the present invention: easily freeze the drawback that cannot use in order to overcome the supply channel in household solar energy water heater winter, the invention 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 technical solution adopted for the present invention to solve the technical problems is: solar water supply system is mainly comprised of valve, pipeline and water tank.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, at the emptying intake valve of the upper end of supply channel connecting pipe, the other end of tube emptying intake valve is connected with the top of water tank, be equipped with respectively with water valve, pipe line evacuation valve and water supply valve the lower end of supply channel, 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, and the other end of pipe line evacuation valve connects sewer pipe.
The starting differential pressure of pressure reduction open check valve is >5kp, valve opening when the water inlet end of pressure reduction open check valve is greater than water side 5kp, valve closing during >5kp.
Pipe line evacuation valve be flow control valve, the PVS value of pipe line evacuation valve is between 0.06 ~ 0.2.
Tube emptying intake valve is low discharge differential pressure control valve, and the PVS value of tube emptying intake valve is between 0.01 ~ 0.05, and when tube emptying intake valve pressure reduction is greater than 10kp, tube 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, the water of whole pipeline will be slow
Discharge by pipe line evacuation valve on ground, the speed emptying due to the water of whole pipeline is slow, the air inflow of tube emptying intake valve can meet the needs that current are discharged, whole pipeline cannot form negative pressure, pressure reduction open check valve cannot be opened, emptying intake valve also cannot cut out, and the water of pipeline will automatic-discharging; During user's water, the flow of water is larger, and the air inflow of tube emptying intake valve cannot meet the needs of user's water, whole pipeline will form negative pressure, and under the effect of negative pressure, pressure reduction open check valve is opened, emptying intake valve method is closed, and guarantees user's water reliably; When water tank need to be gone up water, by pipe line evacuation valve and bathing valve closing, open water supply valve, water flows in water tank by check valve.
The invention has the beneficial effects as follows: the water in can automatic-discharging solar energy pipeline, prevent solar energy pipeline freezing in the winter time, guarantee that solar energy is used reliably.
