Abstract
The present invention discloses a method for preventing drive shaft in the gas valve from loosening and deviating from perpendicular direction. It is characterized by that said method mainly includes the following steps: a), providing a hollow drive shaft; and b), providing a fixing screw bolt in the interior of hollow drive shaft and making said fixing screw bolt be easy slide fit with said hollow drive shaft.
Description
Technical field:
The present invention relates to safety valves for gas manufacturing technology field, particularly relate to the wherein manufacturing technology of transmission shaft.
Background technique:
At present, common safety valves for gas exists screw-thread drive shaft in the course of the work, very easily produces the defective of swing in Vertical direction.For this reason, the technological means that adopts usually is that the two ends of screw thread transmission are inserted in the fixed hole respectively.But can make transmission shaft flexibility variation when rotated again thus.
Summary of the invention:
The objective of the invention is to, provide a kind of and can effectively overcome above-mentioned defective, rotate the method that prevents driving shaft from vertical swinging in the strong flexibly gas valve.To achieve these goals, the technical solution adopted in the present invention is, prevents the method for driving shaft from vertical swinging in a kind of gas valve, and its characteristics are: mainly comprise the following step, a., the transmission shaft of one hollow is provided, and b. provides a standing screw to be slidingly matched with it in it.Owing to adopt such scheme, be not difficult to draw as drawing a conclusion, the present invention is skillfully constructed, the manufacture method of the rational transmission shaft of structure is provided, both kept screw-thread drive shaft to be difficult for producing swing, guaranteed the flexibility of revolution that it is stronger again, the tool promotional value in Vertical direction.
Description of drawings:
Below in conjunction with drawings and Examples the present invention is described in further detail.
The structural representation of the transmission shaft that provides in the inventive method is provided accompanying drawing.
Embodiment:
Referring to accompanying drawing, the transmission shaft 10 of a hollow is provided earlier, provide a standing screw 20 to be slidingly matched again within it with it.Because both are slidingly matched, and standing screw is selected for use from the good material of sliding performance and is made, so guaranteed stronger flexibility of revolution, and close joining can be cheated with the positioning plate axis hole and the nest of gas valve in the two ends of standing screw, also keep screw-thread drive shaft to be difficult for producing swing simultaneously in Vertical direction.
Claims (1)
1, prevent the method for driving shaft from vertical swinging in a kind of gas valve, it is characterized in that: mainly comprise the transmission shaft that the following step: a. provides a hollow, b. provides a standing screw to be slidingly matched with it in it.
