A high-parameter black water angle valve equipped with flow resistance with turbulence and ash collection functions

Abstract

The invention provides a high-parameter black water angle valve with a flow-distributing function and an ash residue collecting function. The high-parameter black water angle valve comprises a valve main body assembly and a valve seat assembly, wherein a valve element assembly is arranged in the valve main body assembly; an inlet cavity is arranged in a side opening of a valve body; an outlet tubeis arranged in a jointing tube; the valve element assembly comprises a valve element and a pushing rod; the pushing rod is arranged in an upper end cover in a penetrating mode, the lower end of the pushing rod extends to the outside of an upper end cover, and the lower end surface of the upper end cover is connected with a valve element; the valve element moves up and down under action of a pushing rod along the axis of the outlet cavity; the upper end surface of a valve base element is arranged below the valve element, and a through hole is formed in a position corresponding to the valve element; a lining assembly is arranged in the jointing tube, and the upper top surface of the lining assembly is connected to the valve seat assembly, and a compression runner is arranged inside the lining assembly; and the inner part of the lining assembly is provided with a through hole, and a solid medium collector is fixedly arranged in the through hole. The high-parameter black water angle valveis simple in structure, is easy in repair and maintenance, easily improves control precision by regulating intensity of throttling effect according to an application working condition, can effectively increase back pressure of the lower part of the valve element, and reduces flow speed of a throttle part of the valve element assembly and the valve seat assembly.

Description

technical field [0001] The invention relates to the technical field of high-end control valves used in coal chemical industry, in particular to a high-parameter black water angle valve equipped with flow resistance with the functions of turbulence and ash collection. Background technique [0002] The black water angle valve is a high-end control valve that can precisely adjust the pressure and flow of the black water medium in the coal gasification section of the coal chemical industry. The performance and reliability of the black water angle valve have a great influence on the safety and stability of the entire coal gasification device. Significant influence. Since the working medium has the characteristics of impurities, corrosiveness, high temperature, and large pressure difference, and the black water angle valve is an unbalanced spool structure, under the action of high pressure difference, strong vibration will occur at the spool of the black water angle valve. Vibrat...

Problems solved by technology

At present, the black water angle valve often adopts multi-stage spool or multi-stage orifice structure for flow resistance design, but the existing multi-stage decompression structure is relatively complicated, the manufacturing cost is high, and the working spool or multi-stage orifice structure It is also susceptible to erosion and wear, and the throttling effect is weakened or even invalid
