Description
Technical field
The present invention relates to petrochemical industry, the new product development of flap type.
Background technique
In domestic and international existing petrochemical equipment, flap type is all single driving mode; Or handwheel drives or hydraulic driving or motor drive or air pressure drives that is:.Except handwheel drives, other driving mode, all needs an auxiliary system, needs precondition; If auxiliary system goes wrong, or precondition disappearance, the pipeline that whole flap type will be made to control or equipment just cannot run.For some important pipeline or equipment, cannot run and just mean heavy economic losses or security incident.The existing solution guaranteeing to run is normally " bivalve configuration ": namely near the valve of automatically control, a hand control valve of connecting; If the pipeline of complexity or equipment, then use how many autocontrol valves, just need to configure how many hand control valves; This not only adds the volume and weight of pipeline or equipment, but also increase the waste of social resources and the economic burden of user.
Summary of the invention
The object of the invention is to design a kind of flap type simultaneously possessing handwheel and hydraulic driving function, when hydraulic driving function is obstructed, promptly can take handwheel driving mode in same valve, thus ensure the normal operation of pipeline or equipment.
The present invention is made up of flap type main body, handwheel driving mechanism and hydraulic drive mechanism, its innovation is: the valve body in flap type main body, in upper end gasket ring and bolt and nut and handwheel driving mechanism, the bottom plane of valve gap is fixedly connected, and in lower end gasket ring and bolt and nut and hydraulic drive mechanism, the upper plane of valve barrel lid is fixedly connected; Ball screw in handwheel driving mechanism, upper end spiral chute is flexibly connected with ball nut, and lower end groove is flexibly connected with the ⊥ shape groove of flashboard upper end in flap type main body; Piston rod in hydraulic drive mechanism, upper end groove is flexibly connected with the T-slot of flashboard lower end in flap type main body, and lower end is inserted in the center hole of piston block, is fixedly connected with screw thread and Cock screw and guide rod upper end.
Because the present invention is in the top and bottom of flap type main body, handwheel driving mechanism and hydraulic drive mechanism are installed respectively; Flashboard in flap type main body, upper and lower two ends are connected with the piston rod in hydraulic drive mechanism with the ball screw in handwheel driving mechanism respectively.When handwheel driving mechanism works, ball screw, under the driving of handwheel and ball nut, drives flashboard, piston rod, piston block and guide rod, moves together up and down, carry out switch to valve; When hydraulic drive mechanism works, piston rod, under the driving of hydraulic oil and piston block, drives guide rod, flashboard, ball screw and ball nut, moves together up and down, carry out switch to valve; Thus realize same valve, carry out the object that hydraulic pressure and handwheel rotation drive respectively, avoid the embarrassment that pipeline or equipment cannot run because of hydraulic system problem, or the drawback of bivalve configuration.
