<p>PURPOSE: To miniaturize a pressure-regulatable water tank, reduce cost by standardization of designs, enlarge the degree of freedom in the setting position of the pressure-regulatable water tank, release regulations of headrace routes resulting from the preset position of the water tank, and develop laying methods of water ways by which a rational usage of water resources can be projected. CONSTITUTION: A flexible hose 17 is fixed to a bag body valve 1 and also fitted to a guide bar 15 for the bag body valve, provided on a support 16. A sealing valve seat 11 is attached to the upper part of the restricted-orifice 12. A discharge pipe 7 pressing air therein, a pressure guage 8 of the air chamber, an air compressor 9, a water level meter 6-1 made of glass plate or tube, are provided in the inside of a pressure container 5.</p> |
