Problems solved by technology

One of the problems with this prior art valve is that the four-way valve is switched by turning the shutoff ball, but is not controllable with respect to flow through one of the flow paths, making it difficult to control the flow if such flow control is required. Then an additional control valve is required

Abstract

Flow control valve, comprising a housing forming a number of internal passages and an internal cavity in fluid communication with each of the internal passages; and a flow direction block disposed inthe internal cavity, the flow direction block having an outer face encircled by an inner face of the internal cavity, wherein the flow direction block comprises two clearances extending through a portion of the flow direction block, wherein each of the two clearances is adapted to selectively connect one pair of the four internal passages of the housing when the flow direction block is rotated around a rotation axis relative to the housing, thus forming a first flow passage and a second flow passage.

Description

technical field [0001] The present invention relates to a flow control valve comprising a housing forming a plurality of internal passages and a lumen in fluid communication with each of the inner passages; and a flow stop disposed in the lumen, the flow stop having a The inner face of the chamber surrounds the outside, wherein the flow stop includes two gaps extending through a portion of the flow stop, wherein both gaps are adapted to select when the flow stop is rotated relative to the housing about the axis of rotation A pair of the four internal passages of the housing are electrically connected, thereby forming a first flow passage and a second flow passage. Background technique [0002] Conventional four-way valves are adapted to receive two inlet streams and provide two outlet streams and may be used where it is desired to switch or vary the flow of fluid to be sent to different components of a fluid system. By way of example, a fluid flow system may employ differen...
