Abstract

The utility model discloses a special drainage and emptying device for solar water heaters, which is used on the original pipeline system composed of water pipes, hot water valves and tap water valves, and another exhaust pipe is connected to the high-end part of the water pipe with a tee Put the tee connected with the water pipe and the exhaust pipe from the top of the water tank and fix it in the polyurethane foam insulation layer of the water tank, the water pipe mouth goes deep into the bottom of the water tank, and the lower end of the exhaust pipe is connected to the air control valve. , It enables the water pipe to be emptied before the water heater is turned off, and there is no need to wrap electric tape on the pipe wall to keep warm, and it can be heated immediately when it is turned on, so as to achieve the purpose of saving electricity, water and energy.

Description

The special-purpose drainage emptier of solar water heater

Affiliated technical field

The utility model relates to the special-purpose drainage emptier of a kind of solar water heater, belongs to machinery manufacturing technology field.

Background technology

Solar energy, as a kind of cleaning, environmental protection, the cost free energy, utilized by human extensive exploitation, solar water heater is wherein a kind of, but, because can't emptying after the water pipe of water heater is closed, water temperature descends rapidly in the pipe, especially in the winter of northern low-temperature cold, can cause water pipe to freeze even spalling is scrapped, for addressing this problem, to when being installed, water heater the water pipe winding be wrapped up, in order to antifreeze with the ribbon heater, insulation, heat up, also have the people on product, to design the magnetic valve emptying, but, because low temperature also can influence the magnetic valve serviceability, damage easily and lost efficacy, need the electric power support equally, therefore, this product also is not really solar product on the pure meaning at present.

Summary of the invention

The utility model provides a kind of solar water heater special-purpose drainage emptier at the problems referred to above, and it can make water heater before closing, water pipe just is drained, need not twine ribbon heater insulation on the tube wall, instant-heating reaches economize on electricity, water saving, energy-conservation purpose.

Task of the present utility model is finished as follows: reached on the pipe-line system that water valve constitutes from the beginning by water pipe, hot water valve original, be connected an other blast pipe on the high-end position of water pipe with threeway, the threeway that will be connected with water pipe and blast pipe is fixed in the water tank Polyurethane insulating foam layer by inserting above the water tank, hose nozzle gos deep into water tank bottom, and the blast pipe lower end connects control valve.

The utility model is the special-purpose emptier of solar water heater, in the parallel inlet chamber with water pipe of blast pipe, the control valve of blast pipe is located at and the hot water valve adjacent position during installation, is convenient to operation, in the time need not using hot water, at first open control valve, air enters threeway by blast pipe, moment blocking-up current, make the water tank of water heater stop at once supplying water, hot water is dirty clean in the gravity effect in the pipe, and the water pipe emptying is closed water control valve and withdrawn; When reactivating, open water valve from the beginning earlier, instantaneous closing, one section of the water pipe that is drained again by water filling, opens hot water valve again, is that physically siphon principle makes water tank hot water be introduced into water pipe again to flow out, go round and begin again, realize the energy-conservation purpose of energy-saving and water-saving.

Description of drawings

Below in conjunction with accompanying drawing the utility model is described in further detail:

Fig. 1 is the utility model overall structure figure

Fig. 2 installs and uses the effect reference diagram for the utility model

Among the figure: 1. water pipe, 2. hot water valve, 3. water valve, 4. blast pipe, 5. threeway, 6. control valve from the beginning.

The specific embodiment

With reference to accompanying drawing 1,2, reach on the pipe-line system that water valve [3] constitutes from the beginning by water pipe [1], hot water valve [2] original, be connected an other blast pipe [4] on the high-end position of water pipe with threeway [5], the threeway that will be connected with water pipe and blast pipe is fixed in the water tank Polyurethane insulating foam layer by inserting above the water tank, hose nozzle gos deep into water tank bottom, and the blast pipe lower end connects control valve [6].

Claims

1, the special-purpose drainage emptier of a kind of solar water heater, it reaches from the beginning by water pipe [1], hot water valve [2], and water valve [3] constitutes, it is characterized in that: reach on the pipe-line system that water valve [3] constitutes from the beginning by water pipe [1], hot water valve [2] original, be connected an other blast pipe [4] on the high-end position of water pipe with threeway [5], the threeway that will be connected with water pipe and blast pipe is fixed in the water tank Polyurethane insulating foam layer by inserting above the water tank, hose nozzle gos deep into water tank bottom, and the blast pipe lower end connects control valve [6].
