Description

Detachable maintenance split stainless steel casting valve Technical Field The utility model relates to the technical field of valves, in particular to a detachable maintenance split type stainless steel casting valve. Background In modern industry and various fluid conveying systems, the split ball valve is widely applied to various industries such as chemical industry, petroleum, natural gas, metallurgy, pharmacy, water conservancy, electric power, building water supply and drainage and the like by virtue of unique advantages such as convenience in installation and maintenance, good sealing performance and the like. In the process of disassembling and maintaining the ball valves, once the ball valves are carelessly operated, the ball valves are easy to fall down due to the loss of support, the ball valves can be damaged, personal injury is easily caused to operators, and great safety risks are brought to maintenance work, and 2, pressure relief and pollution discharge are needed before disassembly, and the prior art is to discharge media in the pipeline by adding an independent blow-off valve, so that a pipeline system becomes complex, and the equipment cost is increased. Disclosure of utility model The utility model aims to provide a detachable maintenance split type stainless steel casting valve so as to solve the problems in the background art. In order to solve the technical problems, the utility model provides the technical scheme that the detachable maintenance split type stainless steel casting valve comprises a first valve body, wherein a second valve body is fixedly connected to the first valve body, a movable pipe is slidably connected to the second valve body, a groove is formed in the movable pipe, a second sealing ring is sleeved in the groove, the second sealing ring is sleeved in the second valve body, a second flange is fixedly connected to one ends of the first valve body and the movable pipe, and a limit ring is fixedly connected to the second flange.
