Abstract

The invention discloses a valve main shaft axial positioning bracket. The valve main shaft axial positioning bracket comprises a bracket body, a bracket support ring and a positioning support ring; the bracket body is fixed on a valve body; the bracket support ring is fixed in the center position of the bracket body, and is coaxial with a main shaft; the positioning support ring is positioned on the main shaft, is axially limited, and can rotate corresponding to the main shaft; and the bracket support ring is in threaded connection with the positioning support ring. The valve main shaft axial positioning bracket effectively solves such problems as inconvenience for main shaft positioning adjustment and error compensation, and is simple and reasonable in structure, low in production cost and long in service life.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to a valve shaft axial positioning bracket. Background technique [0002] In the design of the valve, in order to avoid the axial movement of the main shaft under the influence of factors such as unbalanced force of the medium, machining error and thermal expansion and contraction, the positioning is usually achieved by setting a shaft shoulder on the main shaft, and between the main shaft and the The adjustment is realized by reserving a gap between the valve bodies. This adjustment method has problems such as high processing accuracy requirements and inconvenient adjustment, and even cannot be adjusted when the error is relatively large. Contents of the invention [0003] (1) Technical problems to be solved [0004] The technical problem to be solved by the present invention is how to solve the problems of inconvenient positioning and adjustment of the main shaft and error compe...
