Abstract
The utility model relates to a hydrautic butterfly valve used in a liquid delivery line. The utility model is characterized in that a rocker arm of a valve clack is provided with a piston rod, and a valve body is provided with a piston rod hole provided with a hydraulic cylinder in which a piston and the piston rod are arranged. Besides, the hydraulic cylinder is provided with a hydraulic control system.
Description
The utility model relates to a kind of hydraulic butterfly valve that is used for liquid transmission pipeline.
It is reported that butterfly check valve and the modulating valve kind of using is more at present, but ubiquity has complex structure, volume is big, cost height, deficiencys such as usability difference and function singleness.
The purpose of this utility model is, provide a kind of have reasonable in design, simple in structure, volume is little, cost is low, performance is safe and reliable, is convenient to installation, maintenance, regulation and control, laborsaving, the energy-conservation hydraulic butterfly valve that the safety check function has the modulating valve function again that promptly has easy and simple to handle.
Technical solution of the present utility model is, to achieve these goals, existing butterfly valve is improved, promptly on the flap rocking arm, be provided with piston rod, on valve body, have the piston rod hole, in place, piston rod hole is provided with, be provided with the oil hydraulic cylinder of piston and piston rod, and on oil hydraulic cylinder, be provided with hydraulic control system.
The utility model and background technique are relatively controlled the hydraulic mechanism that flap opens and closes owing to be provided with, therefore on valve body, it not only has simple in structure, volume is little, and cost is low, and performance is safe and reliable, be convenient to install, maintenance, regulation and control, easy and simple to handle laborsaving, advantage such as energy-conservation, and had the function of safety check and modulating valve.
Fig. 1 is structural representation of the present utility model.
Below in conjunction with accompanying drawing, describe a specific embodiment of the present utility model in detail.
Referring to Fig. 1, valve body 1 is a valve body that has inlet/outlet and flap axle axis hole, piston rod hole 8.In flap axle axis hole, flap axle 3 is housed.The flap Rocker arm 4 that has screw hole and piston rod link 9 is installed on flap axle 3.Flap 2 is fastened on the flap Rocker arm 4 by screw rod and nut.Piston rod link 9 is hinge elements.Piston rod 5 is connected with piston rod link 9 by screw thread.The oil hydraulic cylinder 7 of piston 6 and piston rod 5 in having by bolton, the outer end wall in the piston rod hole 8 of valve body 1 is housed.Its piston rod 5 is fastened on the piston 6 by nut.Its oil hydraulic cylinder 7 is connected with the hydraulic control system that is made of oil hydraulic pump, selector valve, one-way valve, outlet valve, relief valve etc. by pipeline.
Its working principle:
When carrying liquid, flap is opened by hydraulic control mechanism.When stopping to carry liquid, flap just can begin to close under liquid flows backwards the effect of pressure, for the water hammer that prevents that liquid from flowing backwards and producing, can piston slowly be moved down by the oil pressure of control oil hydraulic cylinder cavity of resorption, and drive the flap rocking arm by piston rod and slowly rotate along the flap axle, flap is slowly closed, thereby played the effect of Tiny Drag Slow Shut Check Valves.
Because the motion of the piston in the oil hydraulic cylinder can be controlled by hydraulic control mechanism, therefore, the aperture of flap also just can be worked under control, thereby has played the effect of modulating valve.
