Apparently, this kind of valve works by high-precision coupling parts. In addition, it has been working in water for a long time, and the water temperature is constantly changing. The material requirements for the parts are also very high, and the cost is of course very high.
In particular, the emptying valve is idle for a long time. It does not need to be emptying for most of the year. The valve does not work, and it is easy to foul. It is often difficult to start when it is used in winter, and it is very difficult to maintain.
In addition, the power output end of the existing motor and the working rod are mostly concentric docking or gear transmission, which requires too high precision, difficult installation, and prone to failure
The above drawbacks severely limit the popularization and promotion of built-in emptying valves

Embodiment Construction
[0014] The general design of the present invention is: the upper and lower water pipes of the solar water tank enter one end of the water tank to be connected with a flexible hose that can swing under the drive of the driving part to make a built-in emptying valve. When the upper end of the hose exceeds the water surface, it is equivalent to the original valve opening the air inlet, blocking the channel with the water tank, and then the emptying can be carried out; when the upper end of the hose is lower than the water surface, it is equivalent to closing the original valve and entering The air port is connected to the pipeline of the water tank, and the water can be loaded or launched. The hose here can be made of various materials such as silicone or metal bellows. It can be one or only one section, and there are many ways. There are also many forms of hose driving components, as long as the components that can drive the hose to swing are included. For ease of understanding...

The invention relates to a mechanical and electrical product, namely a built-in simple emptying valve of a solar water heater. The emptying valve is connected with one end of an upper and lower water pipe (1) entering into the water tank (16) of a solar water heater. The emptying valve comprises a soft pipe (4) capable of being bent by being driven through a driving part. The emptying valve is characterized in that the driving part is provided with a swinging rod (5) positioned within the soft pipe. The lower end of the swing rod (5) is hinged to one end of the upper and lower water pipe (1) entering into the water tank (16). A push rod (7) is hinged to the swinging rod (5). The other end of the push rod (7) is provided with a motor (13) and a transmission device. When in use, the soft pipe can be bent from bottom to top through a motion part. When the opening of the soft pipe exceeds the water surface, the emptying can be performed. When the opening of the soft pipe is lower than the water surface, the watering or the sewerage can be performed. The emptying valve has the advantages of simple structure and low cost. Due to the adoption of the emptying valve, the icing problem of emptying valves and water pipes can be thoroughly solved. When water is in need, users can directly obtain hot water discharged from a water tank. Therefore, the phenomenon that cooling water is discharged in advance is avoided and unexpected effects are obtained so as to provide conditions for popularizing and applying solar heaters.
Description
technical field [0001] The invention relates to an electromechanical product, namely a built-in simple emptying valve of a solar water heater. Background technique [0002] Solar water heaters are mainly composed of outdoor water tanks, heat collecting pipes, and upper and lower water pipes connected to indoor water pipes. The upper and lower water pipes can both supply water to the water tank and release the hot water in the water tank for people to use. In the cold season in northern my country, the upper and lower water pipes of solar water heaters are prone to freezing. In order to solve this problem, people have adopted various methods, among which the common method is to install an emptying valve. The working principle of the emptying valve is to empty the water in the upper and lower water pipes after the water is supplied or launched, so as to avoid freezing in the pipes. Existing emptying valve is divided into two kinds of external type and built-in type, and ext...
