A vertical type automatic pipeline-burst protecting device is suitable for making a pipeline rapidly and automatically close when the pipeline is overloaded with fluid. The vertical type automatic pipeline-burst protecting device is mainly composed of a cylinder sleeve, a piston, a sphere, a pressure spring, end covers, a plug, a return ejection rod, sealing parts and the like. When the pipeline is overloaded with the fluid, the plug overcomes the self-weight of the plug under the action of the thrust of the fluid to be attached to the end face of the piston, the pressure difference between the two ends of the piston is increased and exceeds the resistance applied by the cylinder sleeve to the piston through the sphere and the self-weight of the piston, and therefore the piston moves towards a fluid outlet; meanwhile, the sphere moves inwards in the radial direction, the included angle between the direction of the force applied by the cylinder sleeve to the sphere and the reverse direction of piston movement is increased, the resistance of the cylinder sleeve on the moving of the piston is decreased, the piston is rapidly attached to the end covers, and accordingly the protecting device rapidly and automatically closes. The vertical type automatic pipeline-burst protecting device is simple in structure, safe, stable, accurate in control and rapid in response.
Description
technical field [0001] The invention relates to a vertical automatic protection device for fluid pipeline burst, the fluid is liquid or gas. Especially suitable for the protection device that can quickly and automatically close when the pipeline bursts and the fluid is overloaded, it is a safety protection facility. Background technique [0002] Existing burst protection devices for fluid pipelines have defects such as complex structures, inaccurate control of fluid overload, poor safety and stability, or incapable of automatic protection. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a vertical automatic protection device for pipeline burst in view of the deficiencies of the prior art. [0004] The technical solution to be adopted in the present invention is: a vertical automatic protection device for pipeline burst, mainly composed of a cylinder liner, a piston, a spherical body, a pressure spring, an inlet ...
