The purpose and characteristic of butterfly valve
Posted by Bundor valve
Butterfly valve can be used to cut off the medium,and can also be used to adjust the flow,it is mostly used in medium low pressure and medium,large diameter valve.The current domestic parameters of butterfly valve are as follows:PN≤PN63;DN50-4800(The maximum diameter of Bundor Valve can do DN3000);Working Temperature≤600℃.
The purpose of butterfly valve
Butterfly valve is recommended under the following working conditions:
1.It is required to throttle,regulate and control flow；
2.Mud medium and medium containing solid particles;
3.Occasions require short length of valve construction;
4.Occasions require fast opening and closing speed;
5.The pressure difference of the occasion is small;
In the double position regulation,shrinkage channel,low noise,cavitation and vaporization phenomenon,a small amount of leakage to the atmosphere,wear medium,you can choose butterfly valve.
When the butterfly valve is used under special working conditions, such as throttling adjustment or strict sealing, serious wear, low temperature and other working conditions, it is necessary to use the specially designed metal hard seal with adjustment device of three eccentric or double eccentric butterfly valve.
The characteristic of butterfly valve
The material of butterfly valve sealing ring is generally rubber and plastic, but the operating temperature is low; If using metal or other high temperature resistant materials to make sealing face, it can be used for high temperature.
Because the butterfly plate movement of butterfly valve with wipe,so most butterfly valves can be used for medium with suspended solid particles,depending on the strength of the seal can also be used in powder and granular medium.It should be noted that the multi-level metal hard seal butterfly valve is not suitable for this working condition,because once the particles enter the non-metallic interlayer, it will affect the sealing performance, and even destroy the sealing surface
The structure length and overall height of butterfly valve is small, the speed of opening and closing is fast,.When fully opened,butterfly valve has a small fluid resistance, when opened to about 15°~70°, and can be flexible flow control, the structure principle of butterfly valve is most suitable for the production of large caliber valve.
