Abstract

The invention discloses a float refrigerant expansion device comprising a float chamber body, a vertical pipe fitting, a float component and a separation component. The float chamber is connected with a bottom plate and a tubular outer casing, and the bottom plate is provided with a first pipe orifice relative to the upper end of the tubular outer casing and comprises a first through hole and a plurality of second through holes. The vertical pipe fitting is fixed on the bottom plate and comprises a second pipe orifice and a third pipe orifice, the second pipe orifice is communicated with the first through hole, and the second through holes on the bottom plate are positioned at the outside of the junction of the vertical pipe fitting and the bottom plate. At least one opening is formed on the pipe wall of the vertical pipe fitting which is adjacent to the side of the second pipe orifice. The float component is sleeved on the vertical pipe fitting for controlling the orifice area of the opening. The separation component is arranged on the bottom plate along the periphery of the float component, thereby constituting an inner flow channel with the tubular outer casing. A plurality of fluid through holes are formed on the separation component which is adjacent to the bottom plate.

Description

technical field [0001] The invention relates to a refrigerant expansion device, and in particular to a floating control type refrigerant expansion device. Background technique [0002] Refrigeration and air-conditioning systems have become a necessity of human life, especially in the case of highly developed industries, the dependence on large-scale refrigeration and air-conditioning systems is increasing day by day. However, such large systems often have the problem of not having a good expansion device available. Especially after the refrigeration system has entered into new technologies such as systematization, multi-stage adjustable or frequency conversion control, manufacturers' demand for expansion devices has increased. [0003] With the development of refrigeration systems, various expansion devices such as orifice plates, short tubes, temperature-sensitive expansion devices, and electronic expansion devices have also been developed and used. However, these expansio...
