Abstract
The utility model discloses a manual metering pump. The manual metering pump comprises a pump case, a piston assembly and locating rods. A connector is arranged on one side of the bottom of the pump case, and the connector is connected with a one-way valve through a union nut. A packing gland is arranged on the top of the pump case, the packing gland is fixedly connected with the two locating rods, and the piston assembly is arranged between the locating rods. The piston assembly comprises a piston and connecting rods. The bottom of the piston penetrates through the packing gland and is movably arranged inside the pump case. A limiting plate is fixed on the tops of the locating rods, a hand wheel is arranged at the central position of the limiting plate, and the hand wheel is fixed on the limiting plate through a bolt and a butterfly nut. The manual metering pump has the advantages that airtight filling is achieved, leakage of additives is avoided, quantitative filling is achieved through the hand wheel and the nut, quantitative filling of multiple dosages can also be achieved, and the maximum working pressure can reach 4.0MPa.
Description
Technical field
The utility model relates to metering pump, relates in particular to a kind of manually-actuated metering pump.
Background technique
In recent years, fuel gas additives in the invention of industrial cutting gas field, make to cut that user uses clean, low-carbon (LC), rock gas becomes possibility cheaply, due to the effect of efficient additive, make rock gas substitute the acetylene of high energy consumption, high pollution, high-risk and propane completely in the use of cutting industry.Because additive must pro rataly be filled in natural gas bottle, equipment of the prior art can not get this effect.Therefore, be badly in need of a kind of improved technology and solve existing this problem in prior art.
