Solar water heater floating ball valve positioning and installation of a new breakthrough
The float valve installed directly inside the solar water heater tank has always been a wish of the solar water heater industry, but because of overcoming the shortcomings of leakage, this desire can not be achieved, so always use a single pipe manually up and down the water approach, though There has been the installation of an external water tank tank and the use of water level signal command solenoid valve to automatically water and control of water level device, but it makes the system complex, beautiful appearance affected, reliability is limited. Five-Star Company carefully analyzed the shortcomings of the floating ball valve installation structure in the hot-water storage tank, avoided the structure of the continuous screw connection, put forward that the float ball valve can be installed externally and prevented the existence of the screw connection in the installation, use and maintenance of the float valve Leakage and installation and maintenance inconvenient problems. The floating ball valve connects the valve body with a positioning groove supporting sleeve which is integrated with the wall of the water tank through a connecting pipe with a positioning pin and is connected with a sealing ring through a reducing joint and an external pipe. In order to prevent the body itself from spraying the water gap and the upper water tank cool, five-star and then use a fully enclosed valve body structure and increase the lever to carry the proportion of practice. This technical feature has a series of superior performance: 1, the float valve outlet parts do not leak. 2, the valve body is completely closed to the water tank hot water spray. 3, off ability, up to 0.8MPa, it will not happen because of high water pressure and leakage phenomenon. 4, the service life of more than double the average float valve length. The float valve was on February 26, 2000 by the State Patent Office granted the patent, according to the Guangdong Provincial Institute of Technology and Information Search search new domestic and no five-star solar water heaters have the same characteristics reported.
