The invention relates to a pneumatic film straight-through single-seat adjusting valve, a pneumatic three-way regulating valve, an electric three-way split-flow regulating valve, a pressure regulating valve, a flow control valve, a flow controller, a dynamic balance valve and a flow balance valve, The regulating valve for regulating the structure of the regulating valve is usually composed of an electric actuator or a pneumatic actuator and a valve body
The straight stroke mainly comprises a straight-through single-seat and a straight-through double-seat type, the latter has the characteristics of large flow capacity, small unbalance force and stable operation, and is particularly suitable for occasions with large flow, high pressure drop and less leakage. The angle stroke is mainly as follows: v-type electric regulating ball valve, pneumatic film cut-off valve, eccentric butterfly valve, etc.
The application flow regulating valve in the pipe network can set the flow directly according to the design, the valve can automatically eliminate the flow deviation caused by the residual pressure head and the pressure fluctuation of the pipeline under the action of water, The valve has the functions of regulating the flow of the pipe network at one time, changing the network control to a simple flow distribution, and effectively solving the hydraulic imbalance of the pipe network. The flow regulating valve is mainly used in the water system such as central heating (cold), so that the flow of the pipe network is distributed according to the needs, the hydraulic imbalance of the water system is eliminated, the problem of hot and cold non-uniformity is solved, the energy is saved, the power is saved by 15-20%,
