The invention discloses a self-tightening sealing structure for a screw-type quick-opening autoclave cover, which relates to the technical field of chemical production equipment. The invention comprises an outer casing, an inner tank, a fixed bolt rod and a sealing gland, wherein the sealing gland and the outer casing are plugged and fixed through the fixed bolt rod; In the present invention, an outer jacket and a fixed bolt rod are arranged outside the inner tank, and an air pressure plug is installed inside the inner tank. When the inner tank is used as a reactor, the internal temperature rises and the pressure is increased due to the reaction, which generates pressure on the air pressure plug to make it slide down and drive the connecting plate. And fix the bolt rod, and then drive the sealing gland to press the composite tank body, so that in the working process, the sealing gland will be pressed more and more tightly with the reaction; The one-way valve structure and the piston structure can discharge air when the connection plate is pressed down and use the air pressure to fix the position of the connection plate, preventing it from being reset during the reaction process or due to pressure fluctuations inside the liner.
Description
technical field [0001] The invention belongs to the technical field of chemical production equipment, in particular to a self-tightening sealing structure of a threaded quick-opening autoclave cover. Background technique [0002] In the existing chemical production technology, the autoclave is a relatively commonly used reaction equipment; in actual use, the reaction is more sufficient by limiting the high-pressure environment of the internal reaction site; therefore, in the sealed environment inside the autoclave, as the reaction process The internal pressure will also change, even fluctuate; the lid of the existing autoclave is usually tightened by simple and rigid bolts when it is tightened, and it is easy to loosen under the fluctuation of internal pressure; therefore, for this To solve this problem, we design a self-tight sealing structure of a threaded quick-open autoclave cover. Contents of the invention [0003] The purpose of the present invention is to provide a...
