Abstract

The invention relates to a two-phase flow ratio mixed transportation valve for constant ratio mixed transportation of two-phase flow in therefining and chemical field. The invention solves the problemof unstable mixed ratio of two-phase flow, wherein the inner cavity of an outer shell is arranged as a counterbore, the left end of the outer shell is provided with a flow inlet hole a, and a mixed transportation hole is formed in the middle of the outer shell; the right end of the outer shell is connected with a cover sealing thread; a flow inlet hole b is formed in the middle of a sealing cover; the inner cavity of a taper sleeve a arranged as a conical hole; the inner cavity of the taper sleeve b is arranged as a conical hole; the taper sleeve a is in threaded connection with the left endof an inner cylinder a; the taper sleeve b is in threaded connection with the right end of an inner cylinder b; and the right end of an inner cylinder is in threaded connection with the left end of aninner cylinder b; a valve core is placed in the inner cavities of the inner cylinder a and the inner cylinder b, and a boss in the middle of the outer circumference of the valve core is positioned between a convex step in the middle of the inner cavity of the inner cylinder a and the convex step of the left end of the inner cavity of the inner cylinder b. The valve provided by the invention can balance the mixed ratio automatically by using the pressure of the two-phase flow, has a simple structure, and is suitable for complicated and variable working conditions.

Description

technical field [0001] The invention relates to a two-phase flow fixed-ratio mixing delivery valve used for two-phase flow constant-proportion mixed delivery in the refining and chemical field. Background technique [0002] In refining and chemical engineering, the mixed reaction of two-phase flow is very common. However, due to the limitations of various natural conditions, especially in the field of oil and gas refining, the long-distance fluid transportation on the station makes the mixed fluid state extremely unstable. During the transportation process The pressure and flow fluctuate greatly, so it is necessary to configure corresponding voltage and flow stabilization equipment. However, depending on the construction situation, due to natural conditions and economic constraints, many occasions cannot be equipped with safe and reliable voltage and flow stabilization systems, which hinders the smooth progress of production operations. Therefore, designing a simple and rel...
