Abstract
The invention relates to a quantitative liquid injection device for dosing of chemical engineering liquid raw materials. The quantitative liquid injection device is composed of a liquid injection barrel, a connecting block, a liquid injection head and a piston rod. A liquid injection hole is formed in the inner side of the lower end of the liquid injection barrel, a rubber plug is arranged at the lower end of the piston rod and connected with the upper end of the liquid injection hole, and the piston rod moves up and down to be in linkage with the rubber plug to enable the rubber plug to be connected with the upper end of the liquid injection hole in contact and sealing mode or separated from the upper end of the liquid injection hole. The upper end of the piston rod is provided with a connecting handle, the connecting block is provided with connecting block threads connected with the liquid injection barrel, the connecting block threads are connected with the threads at the upper end of the liquid injection barrel, the middle of the connecting block is provided with a piston rod connecting hole, and the piston rod is connected with the piston rod connecting hole through a spring. A liquid injection pipe is arranged on one side of the liquid injection barrel which is communicated with the inner cavity of the liquid injection barrel. The quantitative liquid injection device can be connected with an automatic control device conveniently and can control liquid injection precision precisely.
Description
Technical field
The present invention relates to a kind of device of chemical dosing, particularly relate to a kind of quantitative liquid-filling device of chemical liquid feed proportioning.
Background technology
The batching of chemical products needs accurate metering, generally adopts at present measuring pump, but for smaller metering often measuring pump be difficult to control reservoir quantity; Have and adopt manual fluid injection, but work efficiency is too low.
Summary of the invention
