Abstract
A kind of exhaust valve of floating ball locking mechanism, including floating ball, valve rod and split pin；Floating ball is equipped with floating ball pullover, and one end of valve rod is set in floating ball pullover and the two is threadedly coupled；Pin hole is correspondingly equipped on one end of floating ball pullover and valve rod, split pin is inserted into the pin hole on one end of floating ball pullover and valve rod, so that floating ball pullover is connected with one end pin shaft of valve rod；The other end of valve rod and valve seat bracket inside exhaust valve are hinged, and the middle part of valve rod is equipped with buffer rubber gasket, and the flap of buffer rubber gasket and exhaust valve cooperates to realize opening and closing.Pin shaft connection is realized by split pin while floating ball is connect with threaded stem, two kinds of locking mechanism double insurances, increase the safety that floating ball is connect with valve rod, the case where preventing floating ball of the exhaust valve in transport and routine use to be detached from from valve rod, ensure the long-term safe handling of exhaust valve, and in subsequent maintenance, it is convenient for changing floating ball.
Description
Technical field
The utility model belongs to valve technology field more particularly to a kind of exhaust valve of floating ball locking mechanism.
Background technique
Exhaust valve is the essential pipeline air exhaust water equipment of waterline.The Reliability of Microprocessor of exhaust valve is related to entire
The emptying effectiveness of pipeline and safety.According to system operating experience, the failure of existing exhaust valve is frequently appeared on floating ball, especially
It is after operation a period of time, floating ball has the phenomenon that falling off, and brings serious hidden danger to the safe operation of system.This is mainly due to
To be threadedly coupled between the floating ball of existing exhaust valve and valve rod, in transportational process due to jolt and during operation medium frequency
Numerous fluctuation causes thread looseness between floating ball and valve rod, eventually leads to float ball falling, exhaust failure.
Utility model content
The utility model is in view of the above-mentioned problems, provide a kind of exhaust valve of floating ball locking mechanism.
The purpose of this utility model can be realized by following technical proposals: a kind of exhaust valve of floating ball locking mechanism,
Including floating ball, valve rod and split pin；The floating ball is equipped with floating ball pullover, one end of the valve rod be set in floating ball pullover and
The two is threadedly coupled；Pin hole is correspondingly equipped on one end of the floating ball pullover and valve rod, floating ball set is inserted into the split pin
In pin hole on one end of head and valve rod, so that floating ball pullover is connected with one end pin shaft of valve rod.
Further, the floating ball pullover is linked together with floating ball.
Further, internal screw thread is equipped in the floating ball pullover, one end of the valve rod is equipped with external screw thread.
Further, the shaft shoulder, the inner wall of the floating ball pullover are equipped between the screw thread and pin hole on one end of the valve rod
For the hierarchic structure matched with the shaft shoulder.
Further, the other end of the valve rod and valve seat bracket inside exhaust valve are hinged, and the middle part of valve rod is equipped with slow
Rush rubber pad, the flap of the buffer rubber gasket and exhaust valve cooperates the opening and closing to realize exhaust valve.
Compared with the prior art, the advantages of the utility model are: increasing pin hole, floating ball and valve rod on floating ball and valve rod
Pin shaft connection is realized by split pin while threaded connection, two kinds of locking mechanism double insurances, increase floating ball and valve rod connects
The safety connect, the case where preventing floating ball of the exhaust valve in transport and routine use to be detached from from valve rod, it is ensured that exhaust valve
Long-term safe handling, and in subsequent maintenance, it is convenient for changing floating ball.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is floating ball, valve rod and the structural schematic diagram of split pin in the utility model.
Component mark is as follows in figure:
1 floating ball, 101 floating ball pullovers, 2 valve rods, 3 split pins, 4 valve seat brackets, 5 buffer rubber gaskets, 6 flaps.
Specific embodiment
Specific embodiment of the present utility model is described in detail below in conjunction with attached drawing, becomes apparent from those skilled in the art
How ground understanding practices the utility model.Although describing the utility model in conjunction with its preferred embodiment, these
Embodiment only illustrates, rather than limits the scope of the utility model.
Referring to Fig. 1 and Fig. 2, a kind of exhaust valve of floating ball locking mechanism, including floating ball 1, valve rod 2 and split pin 3；It is described floating
Ball 1 is equipped with floating ball pullover 101, and the floating ball pullover 101 is linked together with floating ball 1, and floating ball pullover 101 is used for and valve rod 2
End connection, floating ball pullover 101 is interior to be equipped with internal screw thread, and one end of the valve rod 2 is equipped with external screw thread, and one end of valve rod 2 is set to
In floating ball pullover 101 and the two is threadedly coupled, and pin hole, institute are correspondingly equipped on one end of the floating ball pullover 101 and valve rod 2
It states split pin 3 to be inserted into the pin hole on one end of floating ball pullover 101 and valve rod 2, so that one end of floating ball pullover 101 and valve rod 2
Pin shaft connection.
The other end of the valve rod 2 and valve seat bracket 4 inside exhaust valve are hinged, and the middle part of valve rod 2 is equipped with yielding rubber
The flap 6 of pad 5, the buffer rubber gasket 5 and exhaust valve cooperates to realize opening and closing.
In the specific implementation, the shaft shoulder, the floating ball pullover are equipped between the screw thread and pin hole on one end of the valve rod 2
101 inner wall is the hierarchic structure matched with the shaft shoulder, is further ensured that the structural strength of the junction of valve rod 2 and floating ball 1.
Realize that pin shaft is connect by split pin 3 while floating ball 1 is threadedly coupled with valve rod 2, two kinds of dual guarantors of locking mechanism
Danger, increases the safety that floating ball 1 is connect with valve rod 2, prevents exhaust valve from causing screw thread since road jolts during transportation
The case where loosening and floating ball 1 caused to fall off, be also prevented from exhaust valve in the daily work due to external force cause floating ball 1 fall off and
The case where exhaust valve is unable to operate normally, it is ensured that the long-term safe handling of exhaust valve, and in subsequent maintenance, it is convenient
Replace floating ball 1.
It should be pointed out that can also have a variety of transformation and the implementation of remodeling for the utility model through absolutely proving
Scheme, it is not limited to the specific embodiment of above embodiment.Above-described embodiment as just the utility model explanation, and
It is not limitations of the present invention.In short, the protection scope of the utility model should include those for ordinary skill
It obviously converts or substitutes and retrofit for personnel, and be determined by the appended claims.
