Abstract
The utility model discloses an executer and particularly relates to a hydraulic executer for a large-aperture valve. The hydraulic executer comprises a left end cover, a cylinder body, a right end cover, a left piston and a right piston, wherein an output rotating shaft is arranged in the cylinder body; racks meshed with gears on the rotating shaft are arranged on the left piston and the right piston; a through hole is arranged in the cylinder body wall to form a first channel; a blind hole is arranged on one side of the first channel; a communicated hole communicated with an inner cavity of the cylinder body is arranged on the end surface of the cylinder body; and the communicated hole and the blind hole form a second channel. By adopting double piston gear and rack to drive, the output force is increased by one time compared with the original structure; and in addition, the energy provided by the hydraulic system is several times that of a pneumatic system, the output torque is improved by several times correspondingly, so that utility model is suitable for opening and closing the large-aperture valve. By adopting the direct driving, the utility model reduces the intermediate transitional connection, ensures more reliable driving, improves the driving precision and prolongs the service life.

The utility model relates to a kind of final controlling element, particularly relates to a kind of final controlling element that surges that is used for large bore valves.
Background technique
The final controlling element that surges is a kind of device that is used for the open and close of control valve, is divided into two kinds of straight journey and angle strokes.Wherein the operation pressure of angle stroke is bigger, and its structure generally includes cylinder body, left and right sides end cap, piston and output shaft.Be illustrated in figure 1 as the plan view of the existing valve that surges, ball valve is connected with the final controlling element that surges by coupling, the final controlling element that surges is single piston, the output shaft of final controlling element of surging during work stretches out the technical problem that cylinder body exists corrosion and the dustproof processing of needs outward, drive mechanism is the connecting rod transmission, the gap appears in the long-time running meeting, the transmission accuracy and the working life of final controlling element thereby influence is surged.
The model utility content
The purpose of this utility model provides a kind of final controlling element that surges that is used for large bore valves, its reliable transmission, and long service life has improved transmission accuracy and efficient.
To achieve these goals, the utility model is achieved through the following technical solutions:
A kind of final controlling element that surges that is used for large bore valves, it comprises left end cap, cylinder body, right end cap, wherein left piston, right piston, output revolving shaft are located in the cylinder body, left piston and right piston are provided with the tooth bar that is meshed with gear on the output revolving shaft, be provided with a through hole in the cylinder wall and constitute first passage, be provided with blind hole on one side at first passage, be provided with the intercommunicating pore that is communicated with inner chamber of cylinder block on the end face of cylinder wall, intercommunicating pore and blind hole constitute second channel.
The intercommunicating pore of described second channel and inner chamber of cylinder block is arranged on the junction of cylinder wall end face and left end cap, right end cap.
Described left end cap is provided with the adjusting screw of the opening angle that is used to adjust valve, and right end cap is provided with the adjusting screw of the opening angle that is used to adjust valve.
It has the following advantages the utility model owing to adopted above technological scheme:
1, the utility model has adopted angle stroke transmission, compact structure, owing to adopted the transmission of double-piston gear rack, ouput force has increased by 1 times than original structure, add that energy that hydraulic system provides is more than the several times of pneumatic system, same output torque has also improved several times, so be fit to the keying of large bore valves.
2, adopt direct transmission, reduced the middle transition connection, made transmission more reliable, improved transmission accuracy and efficient, prolonged working life.
