Problems solved by technology

[0002] The traditional mechanical filling valve is widely used in China due to its low cost and simple maintenance. However, in high-speed filling, it is difficult to form a completely equal pressure effect in the bottle and the valve body, resulting in foaming; and the filling flow rate cannot be controlled. Adjustment, after the filling is completed, the liquid level in the container has a large deviation, which needs further improvement

Abstract

The invention relates to an isobaric filling valve. The valve comprises a valve element, a valve body, a valve base, a first diaphragm valve, a second diaphragm valve, a third diaphragm valve, a valvedeck, a feeding pipe, an air cylinder, an air cylinder support, a compression spring, a ventilation block, an air joint, a spiral air flow umbrella and an air pipe. The filling process is divided into the four steps of pressure preparation, quick filling, slow filling and exhausting, isobaric filling is achieved, filling is stable, the liquid level deviation is small, and generation of bubbles isavoided.

Description

technical field [0001] The invention relates to an equal pressure filling valve. Background technique [0002] The traditional mechanical filling valve is widely used in China due to its low cost and simple maintenance. However, in high-speed filling, it is difficult to form a completely equal pressure effect in the bottle and the valve body, resulting in foaming; and the filling flow rate cannot be controlled. Adjustment, after the filling is completed, the liquid level deviation in the container is relatively large, which needs further improvement. Contents of the invention [0003] In view of the present situation of the above-mentioned prior art, the technical problem to be solved by the present invention is to provide an isobaric filling valve which realizes isobaric filling and avoids foaming; and the filling flow rate is adjustable and the liquid level deviation is small. [0004] The technical solution adopted by the present invention to solve the above technical ...
