Description

Carbon steel ball valve convenient to change joint Technical Field The utility model relates to the technical field of carbon steel ball valves, in particular to a carbon steel ball valve with a connector convenient to replace. Background The carbon steel ball valve plays an important role in a pipeline system, the plug body is a sphere, the valve can be opened or closed through rotating 90 degrees, and the carbon steel ball valve has the characteristics of simple structure, convenient operation, reliable sealing and the like, is suitable for various mediums such as water, solvents, acid, natural gas and the like, and is widely applied to a plurality of fields such as chemical industry, petrochemical industry, petroleum, mining, electric power and the like. In a fuel gas pipeline, a carbon steel ball valve is often installed to ensure normal operation and safety control of the pipeline, and when a joint is installed on the carbon steel ball valve, the carbon steel ball valve and the pipeline joint are required to be coaxial, sealing surfaces of two flanges are controlled to be parallel, and bolts on the flanges are required to be symmetrically, successively and uniformly screwed down, and the installation requirements are required to make the installation or the disassembly of the joint more laborious, so that the efficiency of replacing the joint on the carbon steel ball valve is affected. Disclosure of utility model The utility model aims to make up the defects of the prior art and provides a carbon steel ball valve with a convenient joint replacement. In order to achieve the purpose, the utility model provides the following technical scheme that the carbon steel ball valve convenient for joint replacement comprises a carbon steel ball valve body and a pipeline joint, and further comprises: the assembly component is arranged on the carbon steel ball valve body and is used for disassembling and assembling the pipeline joint; The assembly component comprises a fixing piece, wherein the fixing piece is arranged at one end of the carbon steel ball valve body, and threads are arranged on the outer surface of the fixing piece. Above-mentioned, the surface cover of mounting is equipped with the rubber pad, the rubber pad is located between mounting and the pipeline joint. The pipeline joint is matched with the threads and is fixed with the fixing piece. Above-mentioned, the one end of pipeline joint with rubber pad extrusion contact. Above-mentioned, the pipeline joint is provided with different specifications, and pipeline joint and screw thread looks adaptation. Compared with the prior art, the carbon steel ball valve convenient for replacing the joint has the following beneficial effects: 1. According to the utility model, through the cooperation between the pipeline joint and the screw thread, compared with the way of assembling by using the flange, the pipeline joint is only required to be screwed down, so that the pipeline joint is conveniently fixed on the outer surface of the fixing piece, and is further convenient to assemble or disassemble with the carbon steel ball valve body, and therefore, the pipeline joint is convenient to replace. 2. According to the utility model, the rubber pad sleeved on the outer surface of the fixing piece is used, and the rubber pad is matched with the fixing piece and the pipeline joint, so that the fixing piece and the pipeline joint can squeeze the rubber pad when the pipeline joint is screwed down, and the assembling position of the fixing piece and the pipeline joint can be sealed through the rubber pad, and the air tightness of the fixing piece and the pipeline joint is ensured. Additional advantages, objects, and features of the utility model will be set forth in part in the description which follows and in part will become apparent to those having ordinary skill in the art upon examination of the following or may be learned from practice of the utility model.
