Filing valve

Abstract

The invention provides a filing valve belonging to the technical field of liquid delivery devices and solving the problems of more complex structure and high production cost of the traditional filing valve and the problems that the traditional filing valve needs certain conditions when used and can not meet the requirements on certain clients. The filing valve comprises a valve body with a liquid inlet passage, the valve body is internally provided with a valve core seat in a penetrating way; the valve core seat is internally provided with a filling passage communicated with the liquid inlet passage and is internally axially provided with a valve rod in a penetrating way; the valve rod is internally provided with an exhaust passage; one end of the valve rod is fixed with a valve core, and the other end of the same is connected with a driving part; and the valve core seat is provided with an elastic mechanism which can enable the valve core seat and the valve rod to synchronously move when the valve rod axially moves by operating the driving part and enable the valve rod to continuously axially move when the valve core seat supports against a filing opening of a workpiece. The filing valve has the advantages of simple structure, reasonable design, low production cost and use condition and convenient operation.

Description

technical field [0001] The invention belongs to the technical field of liquid conveying devices, and relates to a valve, in particular to a filling valve. Background technique [0002] Barrel beer has been developed in foreign countries for nearly 30 years. The proportion of barrel beer to the total beer production is 30% in Germany, 80% in the United Kingdom, and a considerable proportion in other Western European countries. When barreled beer is repackaged and sold, most of the bottles or glasses are filled with spouts. Filling with spouts will generate a lot of foam during filling, resulting in inaccurate measurement and affecting the reputation of the brand. [0003] There are many types of valves involved, and they are widely used. In order to solve the above problems, some people choose filling valves from existing valves or redesign filling valves with new structures. The main technical documents related to this aspect are as follows: For example, a filling valve [Ch...

AI Technical Summary

Problems solved by technology

The filling valve uses gas pressure to buffer the impulse force generated by the medium when the liquid inlet channel is opened, and solves the problem of inaccurate measurement caused by easy foaming during the filling process (especially when opening), but there are also some defects.

The structure of the filling valve is relatively complicated, and the production cost is high. At the same time, the use of this filling valve also requires certain conditions, which will inevitably fail to meet the needs of some customers.
