Abstract
The invention discloses manually-actuated metering pump, comprise pump case, piston assembly and positioning rod, bottom described pump case, side is provided with joint, described joint is connected with one-way valve by kink nut, described pump case top is provided with Gland, described Gland is fixed with two positioning rods, piston assembly is provided with between described positioning rod, described piston assembly comprises piston and connecting rod, described piston base is located at pump case inside through Gland activity, described positioning rod top is fixed with limiting board, described limiting board central position is provided with handwheel, described handwheel is fixed on limiting board by bolt and wing nut.Advantage of the present invention is: airtight filling, non-additively leaks, and by adopting handwheel and nut to realize quantitative filling, also can realize the quantitative filling of multiple dosage, Maximum operating pressure can reach 4.0MPa.
Description
Technical field
The present invention relates to metering pump, particularly relate to a kind of manually-actuated metering pump.
Background technique
In recent years, at the fuel gas additives of industrial cutting gas art, make cutting user use clean, low-carbon (LC), low cost rock gas to become possibility, due to the effect of efficient additive, make rock gas substitute the use in cutting industry of high energy consumption, high pollution, the acetylene of high-risk and propane completely.Because additive must pro rataly be filled in natural gas bottle, equipment of the prior art can not get this effect.Therefore, the technology being badly in need of a kind of improvement solves this problem existing in prior art.
Summary of the invention
The invention provides a kind of manually-actuated metering pump.
The technical solution used in the present invention is:
Manually-actuated metering pump, comprise pump case, piston assembly and positioning rod, bottom described pump case, side is provided with joint, described joint is connected with one-way valve by kink nut, described pump case top is provided with Gland, described Gland is fixed with two positioning rods, two described positioning rod symmetries are placed, piston assembly is provided with between described positioning rod, described piston assembly comprises piston and connecting rod, described connecting rod is by connecting rod I, connecting rod II and connecting rod III form, described connecting rod II is arc, described connecting rod II one end is fixedly connected with connecting rod III, the other end is flexibly connected with the top of connecting rod I, the bottom of described connecting rod I is movably connected on Gland, piston head is fixed in the contacting point of described connecting rod II and connecting rod III, described piston base is located at pump case inside through Gland activity, described positioning rod top is fixed with limiting board, described limiting board central position is provided with handwheel, described handwheel is fixed on limiting board by bolt and wing nut.
Fixed by nut between described positioning rod and limiting board, Gland.
Described positioning rod is provided with pointer and scale.
Advantage of the present invention is: airtight filling, non-additively leaks, and by adopting handwheel and nut to realize quantitative filling, also can realize the quantitative filling of multiple dosage, Maximum operating pressure can reach 4.0MPa.
