Abstract
The utility model discloses the shaft drive mechanism of a valve and belongs to the technical field of the shaft drive mechanism of a valve. The utility model consists of a moving ring with square holes arranged on the upper end and the lower end respectively as well as an upper shaft and a lower shaft that are connected through the upper square hole and the lower square hole, wherein, a square tenon matching with the upper and the lower square hole of the moving ring is respectively arranged on the lower end of the upper shaft and the upper end of the lower shaft. On the condition that the transmission is not influenced, the shaft drive mechanism of a valve enhances the sealing effect greatly and has strong reliability, simple structure as well as convenient manufacture and installation.
Description
Technical field
The utility model relates to a kind of driving mechanism, is specifically related to a kind of driving mechanism of axle of valve.
Background technique
The mode of bearing transmission is all adopted in the transmission of general valve, and this kind of drive can only adopt the sealing of axially going in ring, and generally all is to select for use 2～3 O shape rubber rings to carry out ring packing; Because O shape rubber ring is squeezed for a long time, rubs, can produce wearing and tearing, distortion, aging, generally after 1～2 year, the phenomenon of seepage will occur, and not reach the effect of sealing.Therefore, change this sealing means, need a kind of new shaft drive mode of design.
The model utility content
Based on above-mentioned need of practice, the purpose of this utility model is: provide a kind of axle is designed to the form of segmentation axle, the sealing of will axially going in ring converts face seal to, thereby forms the shaft transmission of valve of the mechanical seal of face.
The technical solution of the utility model is: a kind of shaft transmission of valve, comprise that upper and lower end has the rotating ring of square hole, and go up axle and lower shaft by what square hole up and down connected respectively, wherein, the upper end of the lower end of last axle and lower shaft is respectively equipped with the square tenon with the upper and lower end square hole form fit of rotating ring.
The square hole cross section of described rotating ring or triangular in shape, or be five square.Relatively rotate the structure that is connected all at the row of the utility model protection domain so long as satisfy not have between rotating ring and the last lower shaft.
Working principle of the present utility model: go up axle and rotate, by the upper aperture drive rotating ring rotation of rotating ring, rotating ring rotates by the moving lower shaft of below pore area, thereby has realized the segmentation transmission.
The beneficial effects of the utility model are: under the prerequisite that does not influence transmission, improved sealing effect greatly, and good reliability, and simple in structure, making, easy for installation.
Below in conjunction with the drawings and specific embodiments the utility model is further specified.
Description of drawings
Accompanying drawing is the utility model embodiment's a structural representation;
Wherein, reference character is:
1 is last axle, and 2 is lower shaft, and 3 is rotating ring, and 4 is square hole, and 5 is the square tenon of last axle lower end, and 6 is the square tenon of lower shaft upper end.
Embodiment
Preferred embodiment
As shown in drawings, a kind of shaft transmission of valve, comprise that upper and lower end has the rotating ring 3 of square hole 4, and go up axle 1 and lower shaft 2 by what square hole up and down connected respectively, wherein, the lower end of last axle 1 is provided with the square tenon 5 with upper end square hole 4 form fit of rotating ring 3, and the upper end of lower shaft 2 is provided with the square tenon 6 with lower end square hole 4 form fit of rotating ring 3.Leave certain clearance between the square hole under the square tenon 6 of the square tenon 5 of last axle and rotating ring upper aperture, lower shaft and the rotating ring, thereby realize that all rotations all are No Load Starts.
In addition; need to prove; the square hole that rotating ring upper and lower end of the present utility model is provided with can be tetragonal, also can be leg-of-mutton, pentagon etc., relatively rotates the structure that is connected all at the row of the utility model protection domain so long as satisfy not have between rotating ring and the last lower drive shaft.The segmentation kind of drive of the present utility model has realized the brand-new mechanical seal of motive sealing employing, axial ring packing is changed into face seal, thereby reach long service life, reliability height.
Claims (2)
1. the shaft transmission of a valve, it is characterized in that: comprise that upper and lower end has the rotating ring of square hole (4) (3), and go up axle (1) and a lower shaft (2) by what square hole up and down connected respectively, wherein, the upper end of the lower end of last axle (1) and lower shaft (2) is respectively equipped with the square tenon (5) (6) with upper and lower end square hole (4) form fit of rotating ring (3).
2. the shaft transmission of valve according to claim 1 is characterized in that: square hole (4) cross section of described rotating ring (3) or triangular in shape, or be five square.
