Abstract
An improved structure of the cold and hot water mixing valve of a balance valve is disclosed. Sealing trenches are installed on the upper surface of the concave portion on the lower wall of the mixing valve gate body and the lower surface of the balance valve cover plate along the water through holes and with a proper distance to the periphery of the upper and lower seats of the balance valve. A balance valve sealing is placed between the two sealing trenches. Sealing trenches are installed on upper surface of the balance valve cover plate and the lower surface of a fixing disk with a proper distance along the periphery of the water through holes. The depths of the sealing trenches are slightly smaller the radii of the cross section of the sealing ring strip for sealing. Therefore, the sealing can be assembled easily. After assembling, the sealing ring strip is positioned steadily. A preferred sealing effect can be derived easily.
