What is the difference between butterfly valve and gate valve? The difference between the two is not well understood by the average layman. In fact, in terms of use, the flow resistance of the gate valve is relatively small, and the sealing performance is better. However, the flow Angle of the valve plate and the related medium of the gate valve is vertical, so if the switch of the valve plate is not in place, the flow of the medium is easy to cause the vibration of the valve plate and damage the sealing ring of the gate valve.
Another name for butterfly valve is flap valve. The role of the butterfly valve is to turn off the switch in the low pressure pipe. Butterfly valve companies can control the existence of many things, such as air and who, as well as various corrosive things in society. In the relevant pipelines, it mainly plays the role of mediation and cutting. The opening and closing parts of the butterfly valve look like a butterfly plate through the disc, which can be rotated around the shaft plate in our own body, and ultimately can achieve the effect of business closure and mediation.
The butterfly valve is driven by the stem. If the rotation is 90 degrees, the closing procedure is reached. The flow rate of the medium can be controlled by adjusting the deflection Angle of the plate.
Working range of butterfly valve and gate valve:
Butterfly valves have many applications, such as natural gas and natural gas industry, liquefied petroleum gas and hot and cold air industry. In the construction industry, butterfly valves can be used to transport a variety of corrosive media, and can also be used for regulating and phase media.
The role of the gate valve here is relatively simple, can only play the role of full opening or full closing, the staff in the sealing surface Angle is easy to lead to deviation, so our gate valve is also called elastic gate valve.
When the gate valve is closed, the sealing effect can only be achieved through the pressure generated by the medium on the sealing surface. Most gate valves are forced sealed. When the gate valve is closed, the external force is used to ensure the sealing performance of the relevant sealing surface.
What is the difference between butterfly valve and gate valve in the way of movement?
When moving, the gate plate above the gate valve works with the stem, also known as the open stem gate valve. The rotation function can be converted into linear motion when passed through the guide groove above the valve body. The fluid path cannot be monitored when the valve is opened. When the full valve is opened, it can be determined according to the position of the ram. When the stem is manually driven, the associated ram can be lifted. This kind of valve is called blind stem gate valve.
After reading the content introduced by the above butterfly valve manufacturers, do you know what is the difference between butterfly valves and gate valves? I hope that the content introduced by butterfly valve manufacturers today can help you understand more about the difference between butterfly valves and gate valves, so as to better distinguish and use the two butterfly valves.
