Double-channel parallel heat exchange valve

Abstract

The invention discloses a double-channel parallel heat exchange valve, and belongs to the field of valves. The double-channel parallel heat exchange valve comprises a hot flow pipe, a pair of cold flow pipes are fixedly connected to the outer wall of the hot flow pipe, the hot flow pipe comprises a heat-resistant pipe, a mounting hole is dug in the heat-resistant pipe, a valve element is rotatablyconnected into the mounting hole, a heat conduction sheet is connected between the cold flow pipes and the valve element, a plurality of evenly-distributed heat conduction columns are fixedly connected to the heat conduction sheet, heat dissipation grooves matched with the heat conduction columns are formed in the outer wall of the heat-resistant pipe and the outer walls of heat exchange pipes, the valve element comprises a hollow valve clack, a sealing plate is fixedly connected to the hollow valve clack, a flow guide cavity is formed in the hollow valve clack, each cold flow pipe comprisesone heat exchange pipe, a threaded hole matched with the flow guide cavity is dug in the middle of each heat exchange pipe, a movable handle is connected into each threaded hole in a threaded mode, cooling fluid can be kept flowing in the valve clack, after the valve clack is impacted by heat flow, heat transmitted to the valve clack exchanges heat with water flow in the valve clack, and the temperature of the valve clack is not prone to rising too high.

Description

technical field [0001] The invention relates to the field of valves, in particular to a dual-channel parallel heat exchange valve. Background technique [0002] Stainless steel pumps and valves are widely used in chemical, petrochemical, petroleum, papermaking, mining, electric power, liquefied gas, food, pharmaceutical, water supply and drainage, municipal, mechanical equipment, electronic industry, urban construction and other fields. The pump is a component that transports various media, and the valve is a control component in the pipeline fluid delivery system. It is used to change the passage section and the flow direction of the medium. Functions such as overflow and pressure relief, the two are often used together; [0003] In the current industry, for example, the maximum working temperature of chemical combustion furnaces is 1300K, but the pressure is very low, usually lower than 1MPa. The "Ramjet Test Facility (RJTF)" in the report of the Japan Institute of Aeros...
