Hand press type liquid working medium filling pot

Abstract

A hand press type liquid working medium filling pot includes a pot body; a hand press piston is arranged in the pot; the hand press piston includes a piston head and a piston rod, the piston head and the inner wall of the pot body are sealed and matched, the piston head is connected to the lower end of the piston rod, the piston rod passes through the pot body upward, and a vent valve is arranged on the upper part of the piston rod; the bottom of the pot body is connected to a connection pipe; the lower part of the connection pipe is connected to a first soft pipe, and the upper part of the connection pipe is connected to a funnel; a first valve is arranged on the upper part of the connection pipe; and the funnel is connected to a second soft pipe. The hand press type liquid working medium filling pot is simple in design principle, is easy to operate, and does not consume any power source; as long as the operation is standard, a liquid medium filled in a heat conducive disc is compact, less liquid medium is leaked, waste almost can be avoided; and the hand press type liquid working medium is low in manufacturing material, is easy to implement, and can be widely promoted and used.

Description

technical field [0001] The invention relates to a hand-pressed liquid working medium filling pot, which is used for manual mechanical filling of liquid medium. Background technique [0002] At present, there are two ways to fill the liquid working medium in the heat conduction coil of the secondary heat exchange solar water heater. One of the easiest filling methods is to place the original medium container at a higher position, and manually use a catheter to suck out and fill it. This filling method is cumbersome, not only will a part of the medium be wasted, but also a small amount of air is often included in the heat conduction coil during filling, which leads to insufficient filling and affects the heat conduction efficiency. Another filling method is to pump in with a mechanical pump. Although this filling method is more convenient to operate and denser, the waste of the medium will be greater. Contents of the invention [0003] In order to solve the above technica...
