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.Existing guarantee run solution normally " bivalve configuration ": namely near autocontrol valve, 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, hydraulic drive mechanism and handwheel driving mechanism, and its innovation is: the upper end of valve body in flap type main body, is fixedly connected with the bottom plane of valve barrel lid in gasket ring and bolt and nut and hydraulic drive mechanism; The upper end of upper end cap in hydraulic drive mechanism, is fixedly connected with cartridge housing, thrust-bearing and the lock screw in handwheel driving mechanism with screw thread and screw hole; Flashboard in flap type main body, upper end ⊥ shape groove is flexibly connected with the groove of piston-rod lower end in hydraulic drive mechanism, and lower end T-slot is flexibly connected with the groove of guide rod upper end; Ball screw in handwheel driving mechanism, upper end spiral chute is flexibly connected with ball nut, and the lower end spiro column and cylindrical body being inserted in the piston rod upper end in piston block center hole in threaded step hole and straight pin and hydraulic drive mechanism is fixedly connected.
Because the present invention is in the upper end of flap type main body, hydraulic drive mechanism and handwheel driving mechanism are installed overlappingly; In hydraulic drive mechanism, the piston rod that lower end is connected with flashboard in flap type main body, the ball screw in upper end and piston block and handwheel driving mechanism is connected into a rigid body.When hydraulic drive mechanism works, flashboard, piston rod and ball screw, along with piston block moves up and down together, carry out switch to valve; When handwheel driving mechanism works, flashboard, piston rod and piston block, together along with ball screw moves up and down, carry out switch to valve; Thus realize carrying out to same valve the object that hydraulic pressure and handwheel rotation drive, avoid the embarrassment that pipeline or equipment cannot run because of hydraulic system problem, or the drawback of bivalve configuration.
