Description
Technical field
The present invention relates to a kind of connection set, relate in particular to a kind of conveniently adjusted Quick Connect Kit for Electric actuator.
Background technique
In Electric actuator, output shaft 1 is output terminal, and output shaft 1 is connected with valve by valve rod joint 2.In prior art, output shaft and valve rod joint are integrated, therefore in the time being connected with the valve of various models, all need its entirety to be processed into the needed Connecting format of valve, and generally be singly-bound on valve rod due to valve, therefore in being connected with valve, can not arbitrarily adjust the position of Electric actuator, especially, in the industry spot of operating mode complexity, need especially to adjust position, use and inconvenience, and had a strong impact on working efficiency.
Summary of the invention
The problem to be solved in the present invention is to provide a kind of processing, use, Quick Connect Kit easy to adjust.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of Quick Connect Kit, comprise output shaft and valve rod joint, and described output shaft and valve rod joint are affixed;
Described output shaft is rotary structure, comprise the first shaft part, the second shaft part and the 3rd shaft part, described the first shaft part, the second shaft part and the 3rd shaft part are affixed successively, the second shaft section diameter size is all greater than the first shaft part and the 3rd shaft section diameter size, and the center position of the first shaft part lower end surface is provided with the first center hole;
Described valve rod joint is rotary structure, comprise the 4th shaft part and the 5th shaft part, described the 4th shaft part and the 5th shaft part are affixed, described the 4th shaft section diameter size is greater than the 5th shaft section diameter size, described the 4th center, shaft part lower end surface is provided with the second center hole, described the 5th center, shaft part upper-end surface is provided with the 3rd center hole, and described the second center hole and the 3rd center hole connect, and in described the 3rd center hole, is provided with a keyway.
Further, the outer peripheral surface of described the first shaft part is provided with a circular groove, Matching installation one seal ring in described circular groove.
Further, described seal ring is O-ring seals.
Advantage and good effect that the present invention has are: adopt the technical program that output shaft and valve rod joint are processed into separation structure, make to process, use, adjust convenient, also can arbitrarily adjust according to the working condition of industry spot the position of Electric actuator, greatly improve working efficiency.
