Abstract
The utility model provides a pipeline vertical automatic protection device that bursts, the rapid self -closing's of pipeline protection device when flow that was applicable to the pipeline fluid transships. The device mainly comprises cylinder liner, piston, spheroid, compression spring, end cover, end cap, return ejector pin and sealing member etc. When the pipeline fluid transships, end cap dead weight and piston end laminating are overcome to the end cap under the effect of fluidic thrust, the pressure differential increase of piston both ends, its pressure differential surpasses the cylinder liner and is used in resistance and piston dead weight on the piston through spheroid, the piston moves to fluid export orientation, spheroid along radial inside removal simultaneously, the cylinder liner is to the anti - angular separation increase of spheroid effort direction with piston motion, the cylinder liner removes the resistance to the piston and reduces, rapid and the end cover laminating of piston, realize the rapid self -closing of protection device. The device simple structure, safety and stability, control are accurate, the reaction rapidly.
Description
Technical field
The utility model relates to a kind of fluid line and to burst vertical automatic safety device, and described fluid is liquid or gas.When being particularly useful for pipeline burst fluid overload, the protective gear that can automatically cut out rapidly, belongs to safety protection facility.
Background technique
The defects such as existing fluid line blow out protection device all exists complex structure, and fluid overload controls accurate, and security and stability is poor or can not automatically protect.
Model utility content
Technical problem to be solved in the utility model is: for the deficiencies in the prior art, provides a kind of pipeline burst vertical automatic safety device.
The technological scheme that the utility model will adopt is: the vertical automatic safety device of a kind of pipeline burst, forms primarily of cylinder sleeve, piston, spherosome, pressure spring, inlet end cap, outlet end cap, plug, sealing gasket, return push rod, end bracket enclosed pad, seal ring and connecting bolt.The axis of protective gear and cylinder sleeve be axially perpendicular to ground.The import of fluid connects end cap below cylinder sleeve, and fluid output connects end cap above cylinder sleeve.Piston is arranged in cylinder sleeve, and is slidably matched with cylinder sleeve circular hole, and piston radial arranges a through hole, arranges a pressure spring in radial direction through hole, and pressure spring two ends arrange a spherosome respectively.The axis of piston arranges several axial hole, and plug is arranged at fluid inlet end.Piston upper end arranges sealing gasket, and return push rod is arranged on outlet end cap, and return push rod one end arranges seal ring, inlet end cap and arrange end bracket enclosed pad respectively between outlet end cap and cylinder sleeve.Connecting bolt connects inlet end cap and outlet end cap.
The cylinder sleeve circular hole intermediate portion of the vertical automatic safety device of pipeline burst arranges a ring groove, and spherosome contacts with ring groove.Cylinder bore wall arranges 1 to 3 cylinder bore wall axial bore, and aperture, cylinder bore wall axial bore two ends arranges the groove be communicated with cylinder sleeve circular hole respectively.
The vertical automatic safety device working condition of pipeline burst, when pipeline burst or fluid flow overload, fluid increases plug thrust, under the Driving force effect of fluid, plug and piston lower surface are fitted, shutoff piston axial hole, piston pressure at two ends difference increases, its pressure difference exceedes cylinder sleeve acts on piston resistance and piston deadweight by spherosome, piston moves to fluid output direction, spherosome radially moves inward simultaneously, the opposite direction angle of cylinder sleeve to spherosome force direction and piston movement increases, cylinder sleeve reduces piston moving resistance, piston rapidly and end cap fit, piston upper end arrange sealing gasket make piston and end bracket enclosed more tight, realize protective gear automatically to close rapidly.
The pressure of input fluid fluids within pipes normally changes, and the pressure of input fluid is large, then the flow in fluid line is also large.The flow flowing through piston axial hole is directly proportional to piston pressure at two ends difference.For avoiding the pressure because of input fluid fluids within pipes to increase, and make fluid line at nominal conditions, the vertical automatic safety device of pipeline burst cuts out voluntarily.End bracket enclosed pad, by being arranged at cylinder bore wall axial bore aperture groove, is extruded open form fluidly passage by fluid.Fluid flows into piston upper-end surface.(fluid pressure do not reach end bracket enclosed pad extruded the intensity opened time pathway closure.) thus to reduce because of input pipeline inner fluid pressure excessive, and piston pressure at two ends difference is increased.
The vertical automatic safety device of pipeline burst can promote return push rod and make piston return after overload is eliminated, and pipeline is resumed work.
Pipeline burst vertical automatic safety device structure is simple, security and stability is high, control is accurate, be swift in response.
