Abstract

The utility model relates to a living apparatus, i.e. a forcible sealing solar water heater water tank. The sealing method of a heat collecting pipe of the prior solar water heater water tank (1) and a functional pipe of the prior solar water heater water tank (1) has two big shortcomings that, firstly, the sealing area of a sealing piece is not big enough for complete coverage; secondly, failures of water leakage or the water feeding of a heat preservation layer occur frequently due to the sole dependence on the spring pressure of the elastic sealing piece and being non-enough pressure; therefore, the manufacture of the forcible sealing water tank is mainly characterized in that a hard board piece applying pressure on one side of the sealing surface of the sealing circle is further arranged on the external side of a sealing circle. The length of the sealing circle of the heat collecting pipe and the sealing area of a sealing ring of the functional pipe are increased. With forceably applying pressure on the sealing piece, the utility model improves the sealing performance of the water tank, prolongs the service life of the sealing piece and overcomes the shortcomings with prior art.
