[0002] The valves used in industrial production are basically connected to the valve core and the driving device through the valve stem. The valve core is located inside the pipeline, and the driving device is located outside the pipeline. It is the weak link of the valve, which may leak after long-term use or poor maintenance; manual valves require on-site operation, and operating valves in dangerous and harmful places or in places that are not easily accessible to the human body may have potential safety or health effects on personnel; In the cold season, the outdoor faucet is easy to freeze and freeze, which will freeze the faucet and make it impossible to use water. Although there are insulation measures for water pipes, in areas with low temperatures, water pipes that have been outdoors for a long time will still be damaged by freezing. For this In this case, if the water pipe is used to prevent the water pipe from freezing and cracking, it will cause a waste of water resources.

specific Embodiment
[0030] (1) For valves in toxic, harmful and dusty places, when operation is required, the operator needs to go to the site to operate, which will endanger the health of the operator. Using this device, it can be controlled remotely. If the valve is installed in the pipe gallery In the narrow place above or in the equipment area, it is not convenient for personnel to operate nearby, and the device of the present invention can also be used for remote operation and control;
[0031] (2) If the fluid in the pipeline is a toxic and flammable medium, the sealing part of the valve may leak and affect safety. By using this device, the sealing leakage can be avoided;
[0032] (3) Large-diameter valves have high manufacturing costs and high prices, and there is no requirement for the opening and closing speed of the valve. By using this device, it can replace large-diameter valves, reduce engineering costs, and save operating costs;
[0033] (4) Outdoor water pipes and other pipes that ...

The invention provides a device and method for controlling the flowing state of pipeline fluid. The device comprises a hard pipeline, an elastic hose, pressure guide rubber pipes and connecting pieces, wherein fluid pipelines needing to be controlled are connected to the two ends of the hard pipeline; the elastic hose is arranged in the hard pipeline; the pressure guide rubber pipes are connected to the two ends of the elastic hose respectively; and the connecting pieces are used for connection at connecting ports among the pressure guide rubber pipes, the elastic hose and the hard pipeline. The elastic hose shows expansion and contraction states in the hard pipeline according to different use states and the characteristic that the elastic hose expands and contracts along with pressure changes, so that the elastic hose plays a role similar to a valve and is used for controlling the flowing state of the fluid in the pipeline, including but not limited to opening, closing and flow control, and the elastic hose can be used in replacement of a valve or extend special functions in necessary occasions.
