Embodiment Construction

[0017] (1) in figure 1 , figure 2 Among them, there are internal helical wires [20] at both ends of the inner pipe wall [4] of the double-flow two-way [1], and the helical directions of the two internal helical wires [20] are opposite, and the outer pipe wall [4] has an intermediate nut [16].

[0018] Screw the two double-flow pipes or other double-flow pipe fittings with outer spiral wires [21] and seals into the double-flow two-way [1] at the same time from the left and right ends, so that the outer pipe wall of the double-flow pipe or other double-flow pipe fittings When the separation wall position mark [22] on [4] is completely aligned, the double-flow pipe or other double-flow pipe fittings are fixed, and then the double-flow two-way [1] is rotated clockwise, and the two pipe heads in the pipe are aligned. They will gradually move closer until they are completely sealed—so that the A fluid [14] and B fluid [15] flowing simultaneously in the dual-flow pipeline can pass...

Abstract

The invention relates to a double flow tube accessory, in particular to a double-circulation (including a double flow cock, a double flow tee joint and a double flow cross which are all called the double-circulation) which enables a double flow tube to form a double flow pipeline or a channel and to be capable of changing directions and branching at will, and enables two kinds of fluids passing through the double flow pipeline or channel not to be mixed.

Description

1. Technical field [0001] The invention relates to a double-flow pipe fitting, in particular to a double-flow pipe (including double-flow and two-way) which enables the double-flow pipe to form a double-flow pipe and pipeline, which can change direction and branch arbitrarily, and the two fluids passing through it at the same time are not confused with each other. , double-flow three-way, double-flow four-way, hereinafter collectively referred to as "double flow"). 2. Background technology [0002] Although the known double-flow pipe fittings have double-flow straight-through and double-flow three-way, its structure is not scientific and reasonable, it is not convenient enough to use, and it lacks double-flow four-way. 3. Contents of the invention [0003] The technical problem to be solved in the present invention is to overcome the shortcomings of the background technology and provide a dual-flow pipe fitting with a simpler structure and more convenient use—dual flow. ...
