Description
Technical field
The present invention relates to butterfly valve technical field, in particular to a kind of novel pneumatic butterfly valves.
Background technique
Butterfly valve is called flap valve, is a kind of simple regulating valve of structure, can be used for the switch control of low pressure pipeline medium
Butterfly valve refers to that closure member (flap or butterfly plate) is disk, and a kind of valve of open and close is reached around valve shaft rotation.Valve can
For controlling the various types such as empty gas and water, steam, various corrosive medias, mud, oil product, liquid metal and radiating medium
The flowing of fluid.Cutting and throttling action are mainly played on pipeline.Butterfly valve opening and closing element is a discoidal butterfly plate, in valve body
Axis around its own rotates, to achieve the purpose that opening and closing or adjusting.Pneumatic butterfly valve is made of pneumatic actuator and butterfly valve.
Pneumatic butterfly valve is to do opening and closing with the round butterfly plate rotated with valve rod, to realize the operated pneumatic valve of enabling movement, is mainly truncated
Valve uses, and also may be designed to have the function of adjusting or section valve and adjust, butterfly valve makes on low pressure medium-large caliber pipeline at present
With more and more.The major advantage of Pneumatic butterfly valve, structure is simple, small in volume, low cost, and the Pneumatic butterfly valve feature is especially
Significantly, it is mounted on high-altitude secret tunnel, controls easy to operate, also regulating flow quantity medium by two-position-five-way solenoid valve.
Existing Pneumatic butterfly valve, when its cylinder breaks down, cylinder cannot control valve open and close again, be situated between in pipeline
The circulation truncation of matter just cannot switch.It breaks down when operated pneumatic valve is opened, is unable to control valve truncation medium, will lead to pipe
Medium constantly flows away in road, causes material waste.It breaks down when operated pneumatic valve is closed, not can control pipeline internal medium stream
It is logical, delay medium conveying, influences to produce.When serious, also it can cannot may be truncated or be discharged due to pipeline medium and cause production thing
Therefore.In order to avoid such case, flexible restoring organ can be equipped in the pneumatic actuator of Pneumatic butterfly valve, when cylinder breaks down
When, flexible restoring organ can be such that cylinder piston rod resets, make valve return to it is initial be turned on or off state, avoid accident.
But a single state that also valve can only be made to keep it turning on or close in this way, still Pneumatic butterfly valve cannot be controlled in cylinder trouble
Change state.
Summary of the invention
Based on the above technical problem, the present invention provides a kind of novel pneumatic butterfly valves, solve existing Pneumatic butterfly valve in gas
When cylinder failure, due to not can control Pneumatic butterfly valve open and close, thus the problem of not can control the circulation truncation of pipeline internal medium.
