Pressure plugging refers to the use of specialized equipment to stop or control the leakage or flow of pressure fluids. The following are several common pressure plugging devices. First, let's look at the butterfly valve. A butterfly valve is a valve used to control or cut off the flow of fluid. It consists of a disc-shaped body and a metal rod fixed to the pipe. Butterfly valves can be adjusted between fully open, fully closed, and intermediate positions to control the flow of fluid. When the butterfly valve is in the fully closed position, the valve body and metal rod will completely block the pipe and prevent the flow of fluid. Butterfly valves are widely used in industrial and construction fields, and have the characteristics of simple structure, small size and light weight. Second, let's introduce the plug valve. A plug valve is a valve that controls the flow of fluid by rotating the spool. The spool of the plug valve can adjust the opening degree of the fluid channel to control the flow of the fluid.

The plug valve has good sealing performance, and when the spool is rotated to the closed position, the fluid channel can be completely blocked to avoid leakage. Plug valves are suitable for high pressure and high temperature working environments, and are widely used in chemical, petroleum and power industries. In addition, we have valve plugs. A valve plug is a device used to temporarily plug a pipe. It is usually made of expandable rubber or metal and can be secured to the pipe by means such as threading or clamping. When the pipe needs to be blocked, insert the valve plug into the pipe and achieve the sealing effect by expanding or clamping. Valve plugs are used to plug pipelines in emergency situations, such as leaks, damage or repairs. Finally, we have valve clearance plugs. The valve gap plug is a common plugging device used to close the gap between the valve and the pipe. It is usually made of cacao disassembled metal and can be fixed between valves and pipes to stop the leakage or flow of fluid. Valve clearance plugs play a key role in valve maintenance, replacement or overhaul to ensure a safe and stable working environment. In summary, pressure plugging equipment plays an important role in the industrial and construction fields, helping to control the flow of pressure fluids and reduce the occurrence of leaks. Different types of sealing equipment with pressure have their own characteristics and application fields, and can be selected according to actual needs.
