Abstract
The invention relates to a heavy punch butterfly valve closing angle adjustor with a spring buffering structure. The heavy punch butterfly valve closing angle adjustor with the spring buffering structure comprises a fixed base, a spring, a stretch-out shaft and a limiting nut; the stretch-out shaft is coaxially arranged in the fixed base in a sleeved manner; the spring is coaxially arranged between the lower bottom face of the stretch-out shaft and the inner bottom face of the fixed base; the limiting nut is installed on the upper portion of the stretch-out shaft and located above the upper end face of the fixed base; and the top end of the stretch-out shaft is located below a heavy punch cantilever. The heavy punch butterfly valve closing angle adjustor with the spring buffering structure is ingenious in design, reasonable in structure, convenient to use and high in practicability. After the product is used, fine adjustment of a valve closing angle can be achieved, squeezing or impacting borne by a sealing ring is further reduced, the service life of a sealing piece is prolonged, and various requirements in the industrial using process are met.
Description
Technical field
The present invention relates to valve technology field, a kind of large-scale weight butterfly valve closing angle when closed
Adjusting means.
Background technology
Weight butterfly valve is generally used for the fields such as power station, water stop, sewage treatment plant, due to the latus rectum of valve
Containing more granule foreign in relatively big and fluid, therefore the sealing member in valve is except having in terms of the manufacturing
Outside higher requirement, it in use be it is also proposed higher requirement, such as prevent excessive compression, anti-
Only impact etc..
At present the most mainly realize preventing from squeezing by controlling its closing velocity during closing
Pressure and impact, produced during being declined by regulation weight due to the closing velocity of valve in hydraulic system
Back pressure is adjusted, and owing to the back pressure of hydraulic system is difficult to accurately control, its fine-tuning capability when fast closedown has
Limit, the ability preventing sealing ring extruding or impact is the most limited, will produce seal failure during long-term use.
Summary of the invention
In place of it is an object of the invention to make up the deficiencies in the prior art, it is provided that one can closedown fast to valve
Time speed be finely adjusted, prevent sealing ring extruding or impact have spring buffer structure weight butterfly valve close valve
Angle demodulator.
It is an object of the invention to be realized by techniques below means:
A kind of weight butterfly valve with spring buffer structure closes valve angle actuator, it is characterised in that: include solid
Reservation, spring, projecting shaft and stop nut, coaxial package projecting shaft in fixing seat, the bottom surface of this projecting shaft
And being coaxially disposed a spring between the inner bottom surface of fixing seat, stop nut is installed on the top of projecting shaft, and this is spacing
Nut is positioned at the top of fixing seat upper surface, and the top of projecting shaft is positioned at the lower section of weight pivoted arm.
And, it being co-axially mounted a fairlead in described fixing seat, this fairlead is arranged at fixing seat and stretches
Between shaft.
And, described fixing seat is made up of cylinder and closure, and closure is coaxially mounted to cylinder body bottom, spring
Lower end top pressure be arranged in this closure.
Advantages of the present invention and good effect be:
1, this actuator compression by compression spring, the increase of its bounce, turn down at valve fast further
Closing velocity time to be closed, is fixed on some by stop nut by closing angle when reaching closedown condition
Value, it is achieved fine setting, thus reduce extruding or the impact that sealing ring is subject to further, the design of this structure both met
Use demand, the most effectively extends the service life of sealing member.
2, the closing angle of this actuator can be finely adjusted, due to logical according to the be squeezed requirement of state of sealing ring
Cross adjustment stop nut setting height(from bottom) position on projecting shaft, the fine setting of valve closing angle can be realized, because of
This this regulative mode is the most simple and convenient.
3, the present invention is that a kind of design ingenious, rational in infrastructure, easy to use, practical have spring and delay
The weight butterfly valve rushing structure closes valve angle actuator, can realize the micro-of valve closing angle after using this product
Adjust, reduce sealing ring further and be squeezed or impact, extend the service life of sealing member and meet industrial application
During requirements.
Accompanying drawing illustrates:
Fig. 1 is the use schematic diagram one of the present invention；
Fig. 2 is the use schematic diagram two of the present invention；
Fig. 3 is the top view of actuator.
Detailed description of the invention
Describe embodiments of the invention the most in detail；It should be noted that the present embodiment is narration
Property, it not determinate, it is impossible to limit protection scope of the present invention with this.
A kind of weight butterfly valve with spring buffer structure closes valve angle actuator, including fixing seat 4, spring 6,
Projecting shaft 3 and stop nut 7, one projecting shaft of coaxial package in fixing seat, also it is co-axially mounted one in fixing seat
Individual fairlead 5, this fairlead is arranged between fixing seat and projecting shaft, and projecting shaft can move up and down along fairlead.
Being coaxially disposed a spring between bottom surface and the inner bottom surface of fixing seat of projecting shaft, this spring is compression
Spring.Fixing seat in the present embodiment is made up of cylinder and closure 8, and closure is coaxially mounted to cylinder body bottom, bullet
Top, the lower end pressure of spring is arranged in this closure.
Stop nut is installed on the top of projecting shaft, and this stop nut is positioned at the top of fixing seat upper surface.At this
In embodiment, pivoted arm 1 hinge of weight is contained in the top of support 2, and fixing seat is arranged on the bottom of support, and stretches
The top of shaft is positioned at the lower section of weight pivoted arm.
The operation principle of the present invention is:
As it is shown in figure 1, there is gap between the top of projecting shaft and the pivoted arm of weight.
As in figure 2 it is shown, when the pivoted arm of weight is rotated down, when rotating to and rack-mount actuator
After projecting shaft contact, projecting shaft can decline along the fairlead in fixing seat, and the spring within actuator also can be by
Compression, therefore the decrease speed of weight can be gradually reduced so that the closing velocity of valve is also gradually reduced；When stretching
Shaft drops to stop nut and the most i.e. completes valve closing with fixing seated connection.Stretching out by adjusting stop nut
Setting height(from bottom) position on axle, can realize the fine setting of valve closing angle.
