Such as static balance Butterfly Valve Products dynamic balance valve
Dynamic flow balance valve is also called self-operated flow control valve, self-operated balance valve, constant flow valve, automatic balance valve, etc. The plug opens automatically and adjusts the opening automatically under the action of the pressure sensitive film to keep the pressure difference between the two ends of the valve relatively constant.The working temperature is - 5 C - 350 C. Besides, it has valve opening index, opening locking device and pressure measuring valve for flow measurement.Manufacturing standard: national standard.0 MPA. By using special intelligent instrument, the flow value flowing through the balance valve can be directly displayed by inputting the valve type and opening value according to the measured pressure difference signal.
In a certain range of pressure difference, the flow through can be effectively controlled to maintain a constant value, that is, when the pressure difference before and after the valve increases, the flow through the valve can be maintained by the action of automatic closing small. As long as the balance valve with appropriate specifications is installed in each branch and user's entrance and debugged once with the special intelligent instrument, the flow rate of each user can reach the set value. It has good flow characteristics.Valve caliber DN15-DN300,Connection mode: flange, internal thread,Driving mode: manual and electric.. Such as static balance Butterfly Valve Products, dynamic balance valve.Valve body material: cast iron, cast steel,Work pressure is 0. It uses differential pressure to adjust the opening of the valve, and uses the change of pressure drop of the valve core to compensate for the change of pipeline resistance, so as to keep the differential pressure basically unchanged when the working condition changes. It automatically changes the drag coefficient according to the change of system working condition (differential pressure).
Its principle is that in a certain flow range, it can effectively control the constant pressure difference of the controlled system, that is, when the pressure difference of the system increases, it can ensure that the pressure difference of the controlled system increases by automatically closing the valve.
The difference between the appearance of the flanged butterfly valve
The difference between the appearance of the flanged butterfly valve and the wafer type butterfly valve is still very large.
The flange butterfly valve has its own name from the body passages at its two ends, relative to the wafer type butterfly valve. Valves, flange type butterfly valves have a longer construction. In addition, due to the structural advantages of the flange butterfly valve, the butterfly valve is more suitable for making large diameter valves, and the scope of application is wider. For the size of the flange butterfly valve, we take the soft-seal worm gear operated flange butterfly valve as an example.
