Precise quantifying mechanism

Abstract

The invention relates to a precise quantifying mechanism. The precise quantifying mechanism comprises a cylinder body arranged vertically, a piston is vertically installed in the cylinder body in a penetrating mode, a second through hole is formed in the bottom of the cylinder body, a second valve body is vertically arranged at the position, corresponding to the second through hole, of the bottomof the cylinder body, an outlet cope-shaped tube is arranged at the bottom of the second valve body, a second valve cover is horizontally arranged in the second valve body, and a second valve seat isvertically arranged in the second valve body, the second valve seat is arranged on the outlet cope-shaped tube, and a second compressed spring is vertically arranged between the second valve cover andthe second valve seat. A first through hole is formed in the right side face of the cylinder body, a first valve body is vertically arranged at the position, corresponding to the first through hole,on the excircle of the cylinder body, a second valve seat is vertically arranged in the first valve body, the first valve seat is tightly attached to the outer surface of the cylinder body, a first valve cover is vertically arranged on the right side of the first valve seat, a first valve cover is horizontally arranged between the first valve seat and the first valve cover, and an inlet pipe is arranged on the right side of the first valve body. The precise quantifying mechanism improves the filling precision.

Description

technical field [0001] The invention relates to a precise quantitative mechanism, which belongs to the technical field of filling mechanisms. Background technique [0002] In blending oil production enterprises, the viscosity of the finished blending oil is high, and its fluidity decreases with the decrease of temperature. Usually, the fluidity needs to be filled through an external pressure device, and the flow rate of the blending oil changes with the change of pressure. Changes, this will cause errors in the amount of oil poured into the oil barrel at different pressures, and there will be too much or too little. Contents of the invention [0003] Based on the above deficiencies in the prior art, the technical problem to be solved by the present invention is to provide a precise quantitative mechanism, which can accurately control the filling oil volume and improve the filling accuracy. [0004] The precise quantitative mechanism of the present invention includes a ver...
