Abstract
The invention discloses a kind of axial limit structure of butterfly valve, including valve body, valve rod, dish plate, end cap, it is characterized in that：The bearing being sleeved on valve rod is set below dish plate, and valve rod is axially supported on end cap by being arranged on a steel ball of stem bottom, steel ring is set below bearing；Steel ring constitutes plane bearing with steel ball, is abutted with bearing；Steel ball periphery sets split annulus, and split annulus is fixed by screws on valve body, and the diameter of bore of split annulus is less than bearing top circle diameter；Steel ring periphery is machined with plane cam groove, is engaged with installed in the guide finger of split circle ring inner wall, and steel ring is provided with adjustment hole, when working long hours, and when steel ball has friction with bearing face, can be moved up by adjustment hole rotating steel rim, steel ring along guide finger.The present invention is rational in infrastructure, and maintenance is convenient, favorable working performance.
Description
Technical field
The present invention relates to a kind of axial limit structure of butterfly valve.
Background technology
The dish plate of traditional butterfly valve is to transmit moment of torsion by pin with valve rod, turns into an assembly, axial limiting after connection
It is to realize by the split annulus of end cap portion, antifriction adjusting pad；Have the disadvantage：Pin connection detachability is poor, split annulus easily with
Valve body be engaged and it is stuck, maintenance rear end cover when, dish plate is moved down with valve rod, destroys the realization of sealing function.
With the lifting of butterfly valve technical property requirements, no pin valve turn between development trend, i.e. upper valve rod and dish version using key,
The form connections such as spline, flat tenon, square tenon, lower valve rod does not make axial limiting part, only serves circumferential spacing effect, the axial direction of dish plate
It is spacing to be directly responsible for by bearing.
The content of the invention
It is an object of the invention to provide one kind is rational in infrastructure, overhaul convenient, the axial limiting of the butterfly valve of favorable working performance
Structure.
The present invention technical solution be：
A kind of axial limit structure of butterfly valve, including valve body, valve rod, dish plate, end cap, it is characterized in that：Set below dish plate
The bearing on valve rod is sleeved on, valve rod is axially supported on end cap by being arranged on a steel ball of stem bottom, below bearing
Steel ring is set；Steel ring constitutes plane bearing with steel ball, is abutted with bearing；Steel ball periphery sets split annulus, and split annulus passes through
Screw is fixed on valve body, and the diameter of bore of split annulus is less than bearing top circle diameter；Steel ring periphery is machined with plane cam groove,
It is engaged with installed in the guide finger of split circle ring inner wall, steel ring is provided with adjustment hole, when working long hours, steel ball and bearing
When end face has friction, it can be moved up by adjustment hole rotating steel rim, steel ring along guide finger.
The present invention is rational in infrastructure, and maintenance is convenient, favorable working performance.
Brief description of the drawings
The invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 is the structural representation of one embodiment of the invention.
Fig. 2 is the structural representation of steel ring.
Fig. 3 is the structural representation of plane cam groove.
Embodiment
Set and be sleeved on below a kind of axial limit structure of butterfly valve, including valve body 1, valve rod 2, dish plate 3, end cap 4, dish plate
Bearing 5 on valve rod, valve rod is axially supported on end cap by being arranged on a steel ball 6 of stem bottom, and coefficient of friction is small；Axle
Hold lower section and steel ring 7 is set；Steel ring constitutes plane bearing with steel ball 8, is abutted with bearing 5, coefficient of friction is small；The setting pair of steel ball periphery
Annulus 9 is opened, split annulus is fixed by screws on valve body, the diameter of bore of split annulus is less than bearing top circle diameter, maintenance
Behind end cap position, dish plate is not moved down；Steel ring periphery is machined with plane cam groove 10, with the guide finger installed in split circle ring inner wall
11 are engaged, and steel ring is provided with adjustment hole 12, when working long hours, when steel ball has friction with bearing face, can pass through regulation
Hole rotating steel rim, steel ring is moved up along guide finger, realizes stepless changing, convenient, accurate.
