Problems solved by technology

[0002] The filling system of infusion medicine generally adopts a high-level tank to store buffer liquid medicine and stabilize the pressure during liquid filling. The high-level tank generally needs to be placed at a height of 5-15 meters, and the liquid pressure can only be controlled below 1 bar. , if you need to increase the pressure, you can only rely on increasing the height of the high tank, which is very troublesome to operate and maintain, takes up a lot of space, slow filling speed, and low production efficiency

Abstract

A pressure balanced tank with stable pouring pressure for the liquid contained in it features that a buffer membrane is used to divide the internal cavity of tank body into an upper gas cavity with gas inlet and outlet having relative gas valves, and a lower liquid cavity with liquid inlet and outlet, and a membrane position indicating column with a lower end in contact with said buffer membrane passes through said gas cavity. It can quickly compensate the pressure loss caused by pouring liquid.

Description

technical field [0001] The invention relates to a pressure balance tank, which is used for accurate filling of liquid medicine. Background technique [0002] The filling system of infusion medicine generally adopts a high-level tank to store buffer liquid medicine and stabilize the pressure during liquid filling. The high-level tank generally needs to be placed at a height of 5-15 meters, and the liquid pressure can only be controlled below 1 bar. , if it is necessary to increase the pressure, it can only rely on increasing the height of the high tank, which is very troublesome to operate and maintain, takes up a lot of space, slow filling speed, and low production efficiency. Contents of the invention [0003] The purpose of the present invention is to provide a pressure balance tank with simple structure, which is convenient for pressure adjustment, meets the filling requirements of liquid medicine, and is beneficial to increase the filling speed and production efficienc...
