PURPOSE:To arbitrary adjust concentration while the concentration of sodium hypochlorate is kept constant in a reciprocal type pump used for a sterilizer injecting sodium hypochlorate into water supply. CONSTITUTION:This is a reciprocal type pump the pressure feed chamber 8 injecting sodium pypochlorate into water supply of which is made up of an intake valve 5, a water feed valve 4, and of a diaphragm 3 made of soft rubber. By the constitution that a screw type adjust nut 10 is fitted onto a piston 1 or a pressure feed plate 2, and a spring 9 is provided for a space between the adjust nut 10 and the pressure feed plate 2 or a space between the piston 1 and the adjust nut 10, concentration can easily be adjusted by adjusting force which is imparted to the pressure feed plate 2 by the piston 1, with the length of the spring 9 changed by the adjust nut 10. |
