The Structure of Butterfly Valve

Source:http://www.flowxgroup.com/Update Time:2014-09-09Hits:

The typical butterfly valve from China as a component of pneumatic actuators has two types. Thin blade valve is a kind of plate valve with small size and thin width. Inside of this size, the valve is on closing place, so it is necessary to make the valve seat and valve fit for each other inside of flow part. Due to the small size of the thin butterfly valve from china, it is possible to use direct bolts to connect three pipe connection flanges without being afraid of leakage due to heat swelling. When it is expected there is heat swelling in large scale, or the adjustment elements cannot cooperate inside of thin butterfly valve, it is possible to use valve with flanges. Another type of the valve is lug type valve. And there is flange with holes conforming to pipe flange on the butterfly valve. Each hole has taper between two flanges. And then it is possible to insert valve whole flange through pipeline flanges. After making sure that double screws have been equipped with whole flange, it is possible to fix the pipeline flange on the valves. Plug valve is used when it is unable to use direct bolts such as heat swelling or it is forbidden to use two flanges with small size valve.

In addition, the butterfly valve from China with tooth profile sealing surface fixed makes sure the position of the flange between pipeline and valves. And the inner size of the butterfly valve from China is close to the pipeline inner size, which is able to permit higher flow and direct to flow.


In addition, the valve plate is able to design as process medium through valve movement so as to reduce the bothering of the material flow. And the butterfly valve from China has been flowed to all over the world. And China is famous for manufacturing small components like butterfly valve, and butterfly valve from China is famous for low price to attract users all over the world. And due to the large demand, the butterfly valve from China is making processes and trying to become the largest component manufacturers in the world. Therefore, no matter from butterfly valve structure or performance, it is necessary for butterfly valve from China to promote its structure and performance to make their butterfly valve better.


In addition, the butterfly valve is a kind of important components of the electric actuator. Therefore, with the booming of the electric actuators, the demand of the butterfly valve from China is growing, so it is necessary to promote the function as well as performance of the butterfly valve so as to make the butterfly valves more popular and crucial.
