Abstract
The utility model relates to a connecting structure for a cylindrical valve hydraulic servomotor and a valve body, wherein the cylindrical valve hydraulic servomotor is arranged on a top cover flange, a hydraulic servomotor piston is installed in a hydraulic servomotor cylinder body, the hydraulic servomotor piston divides the hydraulic servomotor cylinder body into a hydraulic servomotor upper cavity and a hydraulic servomotor lower cavity. The connecting structure for the cylindrical valve hydraulic servomotor and the valve body are characterized in that the cylindrical valve hydraulic servomotor and the valve body are connected through a connecting stud, a sleeve barrel is arranged between a hydraulic servomotor piston rod and the valve body, an upper portion of the sleeve barrel is a pre-tighten gasket, the sleeve barrel is placed in a hole on the top cover flange, and the pre-tighten gasket is located on an upper portion of the top cover flange. The connecting structure for the cylindrical valve hydraulic servomotor and the valve body have the advantages of being big in operation space and easy to achieve, and solving the problem that a machine set needs major dismantling when a seal and other parts in the hydraulic servomotor break down due to a narrow operating space in a flow passage.
Description
Technical field
The utility model relates to the linkage structure of a kind of cylindrical valve servomotor and valve body.
Background technique
The structure that the pattern that present cylindrical valve servomotor is connected with valve body generally adopts is after the servomotor piston rod inserts valve body, to use the breakaway nut pretension; Adopt this kind method to operate connection in flow channels inside; But because the operating space is limited; Actual being difficult to realize, therefore when as installed first, the cylindrical valve servomotor is connected with valve body and on real station, does not carry out.Behind unit operation,,, cylindrical valve servomotor and valve body can't realize in case being connected on the actual station if when the damage of cylindrical valve servomotor seal element need be changed; Must unit be torn open greatly; Promptly hang out rotor and top cover, externally change, this will cause greater loss to the power station.
Summary of the invention
It is bigger that the purpose of the utility model provides a kind of operating space, operation in top cover top machine hole, the cylindrical valve servomotor that is easy to realize and the linkage structure of valve body.The purpose of the utility model realizes through following technological scheme: the linkage structure of a kind of cylindrical valve servomotor and valve body; The cylindrical valve servomotor is installed on the top cover flange, and the servomotor piston is divided into servomotor epicoele and servomotor cavity of resorption with it in the servomotor cylinder body.It is characterized in that cylindrical valve servomotor piston rod connects through being connected double-screw bolt with valve body, between servomotor piston rod and the valve body sleeve is set, upper cartridge is a tightening cushion, and sleeve is in the hole on the top cover flange, and tightening cushion is in the top of top cover flange.
The utility model is when carrying out the dismounting of servomotor piston rod and valve body, and valve body is in fully open position and through lock ingot screw rod valve body is locked ingot behind fully open position, in the oil-filled pressure of servomotor epicoele; The servomotor cavity of resorption oil that runs in is with servomotor cylinder jack-up one segment distance, support block on the pad of its underpart; Then with the servomotor epicoele oil that runs in; The oil-filled pressure of servomotor cavity of resorption, double-screw bolt stretches and with after the tightening cushion dismounting, can and connect the double-screw bolt dismounting with servomotor to connecting.
The dismounting that the utility model has the advantages that cylindrical valve servomotor piston rod and valve body can be implemented in operation in the machine hole, top cover top; The operating space is bigger; Be easy to realize; Solved because of operating space in the flow channels is narrow the problem of when damage parts such as servomotor inner sealing, unit being torn open greatly.

Fig. 2 is the structural drawing when dismantling
Embodiment
The utility model as shown in Figure 1 is the linkage structure of a kind of cylindrical valve servomotor and valve body, and the cylindrical valve servomotor is installed on the top cover flange 6, and servomotor piston 10 is divided into servomotor epicoele 7 and servomotor cavity of resorption 8 with it in servomotor cylinder body 9.Cylindrical valve servomotor piston rod 1 connects through being connected double-screw bolt 3 with valve body 2; Between servomotor piston rod 1 and the valve body 2 sleeve 4 is set; Sleeve 4 tops are tightening cushion 5, and sleeve 4 is in the hole on the top cover flange 6, and tightening cushion 5 is in the top of top cover flange 6.As shown in Figure 2, when carrying out the dismounting of servomotor piston rod and valve body, valve body is in fully open position and through lock ingot screw rod valve body is locked ingot behind fully open position; In the oil-filled pressure of servomotor epicoele, the servomotor cavity of resorption oil that runs in is with servomotor cylinder jack-up one segment distance; Support block on the pad of its underpart is then with the servomotor epicoele oil that runs in, the oil-filled pressure of servomotor cavity of resorption; Double-screw bolt stretches and with after the tightening cushion dismounting, can and connect the double-screw bolt dismounting with servomotor to connecting.
