Problems solved by technology
Due to the special high-humidity environment when bathing, there will be many potential safety hazards, and because the sensor's ultra-long signal line is easily interfered by lightning and other interference sources, the stability is poor
The core component solenoid valve is expensive and expensive
What's more troublesome is that the contact sensor is very easy to scale and cause failure and long-term sealing leakage. Maintenance is quite troublesome. Chinese patent application number 02204649.6 mentions a built-in automatic water replenishment valve for solar water heaters. The valve body is set at the bottom of the water tank and the water inlet pipe The connection is inconsistent with the existing water tank structure, and the installation cost is very high, and the cold water inlet pipe and the hot water outlet pipe are both located at the bottom of the water tank, which seriously affects the thermal efficiency of the solar water heater

The invention discloses a built-in automatic water supply valve of a solar water heater, characterized by comprising a valve body and a valve core which are inserted and connected on the side wall of a water tank. One end of the valve core is movably connected with a float rod arranged in the water tank, and the other end of the valve core extends into the valve body. The connection part of the valve core extending into the valve body and the valve body is provided with a sealing ring, and the outside of the end of the valve body is provided with a thread adapter to connect with a water inlet pipe arranged on the side wall of the water tank. The invention has the advantages of reasonable structure, convenient installation, resource saving and high work efficiency.
Description
technical field [0001] The invention relates to an automatic water supply device for a water tank, in particular to an automatic water supply valve for a built-in solar water heater. Background technique [0002] At present, the water supply valves of solar water heaters on the market mainly include external water tank type water supply valves and electronically controlled water supply valves. And the water pipe freezes and cracks, the pipeline leaks, and the valve body is severely frozen and blocked, which will cause the water tank to deflate. A good quality water tank can avoid the above phenomenon, but the tank is bulky, troublesome to install, and the product price is high. The electronically controlled water supply valve is equipped with an intelligent control module and has complete functions. Although it is convenient to use, the solenoid valve control requires AC power. Due to the special high-humidity environment when bathing, there will be many potential safety ha...
