Abstract
The utility model belongs to a one-way valve core of an automobile control system which comprises a valve core body (5), a valve core external diameter (1) and a valve core inner diameter (4), and is characterized in that a pointedness at the lower end of the valve core external diameter (1) is an oblique angle alpha (3) and the oblique angle alpha (3) is 35-45 DEG. The one-way valve core of the automobile control system has the benefits that the valve core motion is stable, the displacement does not occur, and the control accuracy is high.
Description
Technical field
The utility model belongs to parts in the automotive control system, particularly a kind of nonreturn valve core of automotive control system.
Background technique
One-way valve is parts in the automotive control system, and round is all made in the spool external diameter lower end on spool top in existing part, facts have proved that this round is easy to be squeezed displacement when spool moves, influence the control accuracy of valve.
Summary of the invention
The objective of the invention is to overcome above-mentioned technical deficiency, the nonreturn valve core of the high automotive control system of a kind of control accuracy is provided.
The technological scheme that the utility model technical solution problem adopts is: a kind of nonreturn valve core of automotive control system, comprise valve core, spool external diameter and spool internal diameter, and it is characterized in that the corner angle of the lower end of spool external diameter are made the α oblique angle.The α at α oblique angle is 35 ° ~ 45 °.
The beneficial effects of the utility model are: the spool action is stable, can not produce displacement, the control accuracy height.
