Abstract

The invention provides a high temperature shut-off valve. A valve element assembly comprises a valve element, a valve element cover plate is installed on the top of the valve element in an embedded manner, and a heat insulation chamber is arranged between the valve element cover plate and the valve element; and the bottom surface of the valve element is provided with a bottom surface heat insulation plate, the side wall of the valve element is provided with a side wall heat insulation plate, and cavities are arranged between the bottom surface heat insulation plate and the valve element and between the side wall heat insulation plate and the valve element. A heat insulating structure of the high temperature shut-off valve has the sealing property and has the supporting property. Accordingto the high temperature shut-off valve, a reasonable elongation region is designed for a part in the valve, the part can be extended when the valve works, a belleville spring is compressed, the thermal stress in the valve is greatly reduced, and the reliability of the valve is increased. The valve is fast in action, good in sealing performance and convenient to maintain (only a valve seat and thevalve element need to be replaced), and is mainly used for cutting off high temperature non-oxidizing gas in a pipeline.

Description

technical field [0001] The invention belongs to the field of valves and relates to the control of high-temperature non-oxidizing gases, in particular to a high-temperature cut-off valve. Background technique [0002] In systems that need to cut off high-temperature non-oxidizing gases (ie, inert gases) (for example: test systems where the working fluid is high-temperature non-oxidizing gases), not only good sealing performance but also high reliability are required for the valves. It can work stably under high temperature conditions. The existing high-temperature globe valves in the market are not reliable enough, and the maximum operating temperature is low, which cannot meet the requirements. Contents of the invention [0003] In view of the deficiencies in the prior art, the object of the present invention is to provide a high-temperature cut-off valve to solve the technical problem of insufficient reliability of the cut-off valve in the prior art in a high-temperature...
