Water power proportioning pump

Abstract

The invention provides a water power proportioning pump. An inner cover is arranged in a lower outer shell and divides the lower outer shell into an inner cavity chamber and an outer cavity chamber. An inner cavity of a suction and injection device communicates with the outer cavity chamber. The inner cavity chamber and the outer cavity chamber communicate with an inner cavity of an upper outer shell. A water stop ring plate is integrally arranged on the outer edge of the opening end of an outer piston. The bottom of an upper long rod is connected with a sliding block. A through hole is formed in the middle portion of the sliding block and composed of an upper through hole body section and a lower through hole body section. The diameter of the upper through hole body section is smaller than that of the lower through hole body section. A barb is arranged at the lower end of the upper long rod and penetrates the upper through hole body section in an inserted manner to stretch into the lower through hole body section. One end of a reversing telescopic piece abuts against an arc concave groove, and the other end of the reversing telescopic piece abuts against an arc groove. An upper blockage piece used for blocking a liquid outlet hole is arranged on the outer edge of the upper end of an inner piston, and a lower blockage piece used for blocking a liquid inlet hole is arranged at the bottom of the inner piston. The water power proportioning pump has the beneficial effects that according to the chemical adding mode, chemical adding is achieved outside a cavity, the liquid chemical does not enter the chemical adding device cavity, and the cleaning frequency can be reduced.

Description

technical field [0001] The invention relates to a proportional pump, in particular to a hydrodynamic proportional pump. Background technique [0002] In the background technology, the horticultural industry, animal husbandry industry and industrial fields need to carry out constant dilution of special solvents, and other industries such as car washing, printing, hospitals, wine industries, etc. also often need to carry out constant dilution of solvents. The application of the above industries or the use of traditional operation methods, the labor cost is too high, the rationality of the ratio is poor, and the safety and sanitation cannot be fully guaranteed. Or use a more intelligent device, but it will use electricity, consume energy, and increase production costs. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a hydrodynamic proportional pump, which does not consume electric energy, is energy-saving and envir...
