Embodiment Construction

[0021] The present invention is described in detail below in conjunction with accompanying drawing:

[0022] figure 1 Schematic diagram of the structure and principle of the control valve. The actuator is hydraulically driven (electric or pneumatic as required), the lower end 9 of the piston rod of the hydraulic cylinder 1 is screwed together with the head thread 18 of the flexible connection kit 5, and the lower end of the valve stem 8 of the adjustment mechanism is connected to the lower end of the control valve. The spools 7 are connected to each other, and the upper end is made into an I-shape, and is nested in the I-shaped groove 20 of the flexible connection set 5 . When the piston 3 of the hydraulic cylinder 1 moves up and down, it will drive the spool 7 of the control valve to move up and down through the lower end 9 of the piston rod, the flexible connection kit 5 and the valve stem 8, and adjust the valve opening of the control valve.

Abstract

The invention discloses a control valve flexible connection kit which comprises a left lug ring and a right lug ring. A groove matched with the top end of a valve rod is formed between the left lug ring and the right lug ring, and the left lug ring and the right lug ring are connected to the two ends of a large round pin in series respectively. The middle of the large round pin is provided with a small hole perpendicularly crossed with the axis of the large round pin and penetrating through the large round pin, and a small round pin connecting the large round pin and an upper seat arc shaft frame penetrates through the small hole. The upper seat arc shaft frame is sleeved with an antiskid force-evening spring capable of exerting pre-tightening force on the upper seat arc shaft frame, and the large round pin and the small round pin are surrounded by the antiskid force-evening spring. The upper end of the antiskid force-evening spring abuts against an upper seat, the lower end of the antiskid force-evening spring abuts against the left lug ring and the right lug ring, and the upper seat is provided with a head thread matched with a piston rod.

Description

technical field [0001] The invention relates to a kit for flexibly connecting an actuator and an adjustment mechanism of a control valve, which belongs to the technical field of control valves. Background technique [0002] In industrial production control systems, a control valve is a terminal element formed by a power-operated device, consisting of a valve part with an internal regulating mechanism that changes the flow rate of a fluid. The valve component is connected to the actuator and responds to the signal from the control element. For straight-stroke control valves, in the actual installation process, it is difficult to make the output shaft of the actuator completely coaxial with the input shaft of the adjustment mechanism, so the force of the actuator acting on the adjustment mechanism will be unbalanced. If the traditional rigid connection is adopted between the actuator and the regulating mechanism, it is easy to cause the valve stem of the regulating mechanism ...
