Abstract
The utility model discloses a kind of automobile booster vent valve valve rod pretightening force controlling mechanism.Specifically, it is the valve rod of adjustable in length.It includes valve rod and hollow stem, and there is screw thread valve rod outer end, has locking nut on the thread segment of valve rod outer end.It is characterized in that there is U-frame hollow stem one end, two perpendicular section ends of U-frame are integrated with being formed on the outside of hollow stem one end, are covered among the crosspiece of U-frame formed with the circle concentric with hollow stem.There are the cylindrical nuts coordinated with its activity in U-frame, after the valve rod outer end covers through circle, then screw in cylindrical nuts.Using this governor motion, it is not required to dismantle, screw hollow stem, regulation is got up more convenient.Adjusted suitable for the valve rod pretightning force between automobile booster deflation valve body and valve.
Description
Technical field
It the utility model is related to a kind of rod member.Specifically, it is the valve rod of adjustable in length, be particularly suitable for use in automobile booster
Valve rod pretightning force regulation between deflation valve body and valve.
Background technology
Both known about in automobile booster manufacturing, the valve rod outer end of the vent valve of automobile booster is both provided with pretightning force
Governor motion.This pretightening force controlling mechanism includes valve rod and hollow stem, and valve rod outer end is threaded equipped with locking nut, empty
There is internal thread core bar one end, and valve rod outer end is screwed in the female one end of hollow stem band.Under installment state, the hollow stem other end
Detachably it is connected in the middle body case of booster by key seat and pin.When need to adjust between deflation valve body and valve rod
Pretightning force when, it is necessary to the one end being connected to hollow stem on booster intermediate body could be by screwing reality after being unloaded from pin
Now between deflation valve body and valve rod pretightning force regulation, to reach needed for pretightning force, it is necessary to be repeated a number of times dismounting, screw
Hollow stem, regulation are got up cumbersome.
Utility model content
Problem to be solved in the utility model is to provide a kind of automobile booster vent valve valve rod pretightening force controlling mechanism.
Using this governor motion, it is not required to dismantle, screw hollow stem, regulation is got up more convenient.
Above mentioned problem to be solved in the utility model is realized by following technical scheme：
Automobile booster vent valve of the present utility model includes valve rod and hollow stem, valve rod with valve rod pretightening force controlling mechanism
There is screw thread outer end, has locking nut on the thread segment of valve rod outer end.Being characterized in hollow stem one end has a U-frame, two of U-frame
Perpendicular section end is integrated with being formed on the outside of hollow stem one end, is covered among the crosspiece of U-frame formed with the circle concentric with hollow stem.U
Shape inframe has the cylindrical nuts coordinated with its activity, after the valve rod outer end covers through circle, then screws in cylindrical nuts.
Because there are U-frame, two perpendicular section ends of U-frame and hollow stem in hollow stem one end it can be seen from above scheme
Formed and be integrated on the outside of one end, covered among the crosspiece of U-frame formed with the circle concentric with hollow stem.Have in U-frame and its activity
The cylindrical nuts of cooperation, after the valve rod outer end covers through circle, then screw in cylindrical nuts.When the valve rod that need to adjust vent valve is pre-
During clamp force, only cylindrical nuts need to be screwed, so that it may realize the length adjustment of valve rod, and then realize the pretightning force regulation of valve rod.With the back of the body
Scape technology is compared, and is not required to unload one end of hollow stem from the intermediate of booster, is not required to be repeated a number of times dismounting, is screwed
Hollow stem, so that it may realize the pretightning force regulation of valve rod, regulation is got up more convenient.
Brief description of the drawings
Fig. 1 is automobile booster vent valve valve rod pretightening force controlling mechanism schematic diagram of the present utility model；
Fig. 2 is Fig. 1 A-A schematic cross-sectional views.
Embodiment
As depicted in figs. 1 and 2, automobile booster vent valve of the present utility model includes valve with valve rod pretightening force controlling mechanism
Bar 1 and hollow stem 5, the outer end of valve rod 1 are threaded, and are furnished with locking nut 7 on the thread segment of the outer end of valve rod 1.The one of hollow stem 5
End is machined with radial hole, and during installment state, the end of hollow stem 5 is arranged on by radial hole in non-rotatable shape and booster
On the universal driving shaft 4 that relief valve valve is connected as a single entity, the other end of hollow stem 5 is provided with U-frame 6, two perpendicular section ends of U-frame 6
It is integrated respectively with being formed on the outside of the end of hollow stem 5, formed with the circle set 2 concentric with hollow stem 5 among the crosspiece of U-frame 6.
The cylindrical nuts 3 coordinated with its activity are provided with U-frame 6, the outer end of valve rod 1 screws in again after passing through circle set 2 in moving type
In cylindrical nuts 3.When 1 pretightning force of valve rod of vent valve 8 need to be adjusted, cylindrical nuts 3 only need to be screwed, so that it may realize valve rod 1
Length adjustment, and then realize the pretightning force regulation of valve rod 1.
