Problems solved by technology

It wastes water resources, and also limits the use of solar water heaters on floors with large height differences
When the temperature drops below the freezing point in winter, the water in the upper and lower water pipes may freeze, which not only affects normal use, but also easily bursts the upper and lower water pipes
Most of the existing solar water heater water pipe emptying devices do not consider their own antifreeze problem
[0003] In addition, when the water tank of the solar water heater and the ordinary water tank used in conjunction with it are full of water, the water will overflow, resulting in a waste of resources.
The existing anti-overflow equipment has a complex structure, or needs to be installed in the water tank, which is inconvenient for installation and maintenance

Embodiment 1

[0054] An anti-overflow and emptying device for a solar water heater is composed of a pressure control unit [1], an emptying check valve [2] and a pressure valve [3]. Assembly diagram as figure 1 shown.

[0055] The pressure control unit [1] is installed on the exhaust port [4] or overflow port [5] of the solar water heater tank, and another opening is closed; when the pressure in the solar water heater tank exceeds the design pressure, the pressure control unit [1] The decompression mechanism of the pressure control unit [1] is opened, and air enters the solar water heater tank, and the water flows from the The upper and lower nozzles [6] flow out, and the air intake mechanism of the pressure control unit is closed, so the water cannot flow out under the action of atmospheric pressure; a filter screen [7] is installed at the upper and lower nozzles [6], on the one hand, it can prevent sundries from entering the water tank, On the other hand, the surface tension of water can...

Embodiment 2

[0070] This embodiment provides another implementation of the pressure valve [3], and other components and structures are the same as those in Embodiment 1.

[0071] Such as Figure 4 As shown, the pressure valve [3] can also be composed of a pressure valve housing [301], a rotating cover plate [305], a cover plate base [306], a diaphragm [308], a pressing plate [307], a transmission mechanism [309] and a pressure valve The protective cover constitutes.

[0072] The middle of the pressure valve housing [301] is empty, as a water flow channel; A-A and B-B sections are as Figure 5 As shown; the pressure valve housing [301] has a control port [302], a rotating cover installation port [303] and a pressure plate installation port [304], and the rotating cover installation port [303] is located at the control port [302] by the water source end side; the rotating shaft of the rotating cover [305] is installed on the cover base [306], and a return spring is installed on the rotatin...

Embodiment 3

[0077] This embodiment provides another implementation of the pressure valve [3], and other components and structures are the same as those in Embodiment 1.

[0078] Such as Image 6 Shown, pressure valve [3] can be made of pressure valve housing [321][322], rotary cover plate [325], pressure piston mechanism and transmission mechanism [330].

[0079] The middle of the pressure valve housing [321] [322] is empty, as a water flow channel, the A-A section is as Image 6 As shown, the C-C section is as Figure 7 As shown, the D-D cross-section is a ring; the pressure valve housing [322] has a control port [323] and a pressure piston installation port [324]; the pressure valve housing [321] [322] is fixed together; the rotating cover [ The rotating shaft of 325] is installed on the pressure valve casing [322], and return spring is installed on the rotating shaft, provides the active force close to the inner wall of pressure valve casing [321] for rotating cover plate [325].

Abstract

The invention provides a solar water heater overfilling-prevention and emptying device, belongs to the field of solar water heater water pipe overfilling-prevention and emptying, and also relates to the field of overfilling-prevention of common water tanks. The device consists of a pressure control unit [1], an emptying one-way valve [2] and a pressure valve [3]. The pressure valve can be independently used for overfilling-prevention water supply control of a water tank and a water channel sharing water supply and water drainage pipes. The device has a simple and practical structure, can effectively solve the problems of overfilling-prevention and emptying of a solar water heater and a water supply overfilling-prevention problem of other water tanks sharing water supply and drainage pipes, and also has good freezing prevention performance. Besides, a hand operated mechanism provided by the invention can make the solar water heater normally used under the condition of power failure. The device can save precious water resource, and makes the application of the solar water heater wider so as to save energy used for heating.

Description

technical field [0001] The technical field of the invention is the field of overflow prevention and emptying of water pipes of solar water heaters, and also relates to the field of overflow prevention of common water tanks. Background technique [0002] The solar water heater is installed on the roof, and after use, water will be stored in the upper and lower water pipes. When using next time, the water stored in the upper and lower water pipes has been cooled, and it needs to be drained to obtain hot water. Water resources are wasted, and solar water heaters cannot be used on floors with large height differences. When the temperature drops below the freezing point in winter, the water in the upper and lower water pipes may freeze, which not only affects normal use, but also easily bursts the upper and lower water pipes. Most existing solar water heater water pipe emptying devices do not consider the antifreeze problem of self. [0003] In addition, when the water tank of...
