Concrete optimization measure of the present utility model comprises: be provided with O-ring seals at described piston and valve rod junction, described piston is positioned at fluid cylinder, is provided with caulking gum spare at piston and fluid cylinder junction.The upper end of described valve gap has and extends upward, is with externally threaded flange, and the lower end of adpting flange has the internal thread that matches with external screw thread on the flange, makes adpting flange be threaded with valve gap.Described adpting flange is fixedlyed connected with fluid cylinder by soket head cap screw, and its upper end is stretched in the fluid cylinder, is provided with caulking gum spare in the upper end and the fluid cylinder inwall contact site of adpting flange, and described adpting flange and valve rod junction are provided with O-ring seals.
Advantage of the present utility model is: the hand of the present utility model flap type that surges is rational in infrastructure, easy to operate, good stability, at flap type fluid pressure drive device is installed, and fitting operation bar and handwheel again on the fluid pressure drive device, can realize the liquid integrated control of hand, avoid occurring because of hydraulic control system go wrong can't valve-off phenomenon, the safety factor height.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the structural representation of the utility model embodiment one.
Comprise valve 1, valve gap 2, adpting flange 3, soket head cap screw 4, fluid cylinder 5, valve rod 6, piston 7, nut 8, fluid cylinder lid 9, action bars 10, handwheel 11, plug 12 among the figure.
The specific embodiment
Embodiment one
The hand of the present embodiment flap type that surges, its structure as shown in Figure 1, comprise valve 1 and by being bolted to the valve gap 2 on the valve 1, valve gap 2 is connected with fluid pressure drive device by adpting flange 3, the upper end of valve gap 2 has and extends upward, is with externally threaded flange, the lower end of adpting flange 3 has the internal thread that matches with external screw thread on the flange, makes adpting flange 3 be threaded with valve gap 2.Fluid pressure drive device comprises fluid cylinder 5 that is installed on the adpting flange 3 and the valve rod 6 that is arranged in fluid cylinder 5 inner chambers, adpting flange 3 is fixedlyed connected with fluid cylinder 5 by soket head cap screw 4, its upper end is stretched in the fluid cylinder 5, is provided with caulking gum spare in the upper end and the fluid cylinder 5 inwall contacts site of adpting flange 3; Fluid cylinder 5 is provided with the fluid cylinder lid 9 of band action bars 10, is specially fluid cylinder 5 and stretches into fluid cylinders in the fluid cylinder 5 by soket head cap screw and an end and cover 9 and fixedly connected, and fluid cylinder lid 9 and fluid cylinder 5 contacts site are provided with caulking gum spare; Have tapped passage on the fluid cylinder lid 9, the action bars 10 of band handwheel 11 is set in the passage, action bars 10 is connected with piston 7 contacts that are enclosed within valve rod 6 upper ends; The lower end of valve rod 6 passes adpting flange 3 successively and valve gap 2 valve plate interior with being arranged on valve 1 valve pocket is connected, and adpting flange 3 is provided with O-ring seals with valve rod 6 junctions.Wherein, the lower end of piston 7 has the valve rod hole that allows valve rod 6 to pass, the upper end has the groove that is communicated with valve rod hole, the nut 8 that is threaded with valve rod 6 is set in the groove, like this, valve rod 6, piston 7 can be connected as a single entity by nut 8, piston 7 is provided with O-ring seals with valve rod 6 junctions, piston 7 is positioned at fluid cylinder 5, is provided with caulking gum spare in piston 7 and fluid cylinder 5 junctions.
