Let us know the scope of application and structure of electric butterfly valve?
Do you know what the electric butterfly valve is used for and what structure it is composed of? Here is a detailed introduction.
The electric butterfly valve (VibrationDamper) is mainly used to restrain the vibration of the butterfly valve after shock absorption and rebound and the impact from the road surface. When passing uneven roads, although the vibration absorption butterfly valve can filter the vibration of the road surface, the butterfly valve itself will have reciprocating motion, and the electric butterfly valve is used to restrain the jump of the butterfly valve. If the electric butterfly valve is too soft, the body will jump up and down. If the electric butterfly valve is too hard, it will bring too much resistance, which will hinder the normal operation of the butterfly valve. During the modification of the suspension system, the hard electric butterfly valve should be matched with the hard butterfly valve, and the hardness of the butterfly valve is closely related to the vehicle weight. Therefore, the heavier vehicles usually use the hard electric butterfly valve. The device connected with the vibration inducing crankshaft is used to counter the vibration of the crankshaft.
The structure of the electric butterfly valve is that the piston rod with the piston is inserted into the cylinder to flush the oil in the barrel. The piston is provided with an orifice so that the oil in the two spaces separated by the piston can supplement each other. Damping is generated when viscous oil passes through the orifice. The smaller the orifice, the greater the damping force. The greater the oil viscosity, the greater the damping force. Assuming that the size of the orifice is unchanged, when the electric butterfly valve operates at a high speed, excessive damping will affect the absorption of impact. Therefore, a disc shaped leaf spring valve is set at the outlet of the orifice. When the pressure increases, the valve is jacked open, the orifice opening increases, and the damping decreases. Because the piston moves in both directions, leaf spring valves are installed on both sides of the piston, which are called contraction valves and extension valves respectively.
