Novel quick connector for natural gas pipeline of spray gun of top-blown furance

Abstract

The invention discloses a novel quick connector for a natural gas pipeline of a spray gun of a top-blown furance. The connector comprises a natural gas pipeline, a clamping base, a sealing shell, a first sealing ring, a second sealing ring, a first quick clamping assembly, a second quick clamping assembly and a spray gun gas inlet pipe. In the invention, the clamping base and the sealing shell are clamped and fixed in a step manner; the first sealing ring and the second sealing ring are also arranged between the clamping base and the sealing shell, so that the connector is good in sealing property and easy to mount; when the spray gun is connected with a natural gas pipeline, a first clamping jaw and a second clamping jaw are clamped to a protruding clamping table, then a force application arm is moved backwards and downwards, under the action of tensioning force, a fixing base drives the sealing shell to abut against one side of the clamping base, clamping and fixing of the clamping base and the sealing shell are achieved, and the structure is light, flexible and high in adaptability, and can be disassembled and assembled on site by one to two persons; On large equipment of a smelting process, labor, time and effort are saved, and more economic benefits can be generated.

Description

technical field [0001] The invention specifically relates to the technical field of quick connectors, in particular to a new type of quick connectors for natural gas pipes of spray guns of top blowing furnaces. Background technique [0002] The burner for heating up the kiln generally uses a spray gun, which is the key heating equipment. [0003] The traditional method of connecting the spray gun and the natural gas pipeline is to use flanges, but when replacing the spray gun or the natural gas hose, the operation time is long, the bolt holes are easily misplaced, and the sealing effect is not very good. Only the operation can be done, which wastes time and effort. Contents of the invention [0004] The purpose of the present invention is to provide a new type of top-blown furnace spray gun natural gas pipe quick connector, to solve the problem that the traditional spray gun and natural gas pipeline connection method proposed in the above background technology is to use f...
