Basic principle of dynamic resistance balance pneumatic valve 1)

the dynamic resistance is differential pressure balance ZLY type pneumatic valve, pneumatic valve/flow control is a new kind of balance of pneumatic valve. It is not only a control flow, but also controls a multifunctional pressure pneumatic valve, pneumatic valve switch to the transition of flow control and pressure control. Hebei when the flow rate of the dynamic characteristics of pneumatic valve and the use of force balance pneumatic valve, you can have a flow pneumatic valve, direct and easy to set up, on the basis of all of the design process, according to the role of water pneumatic valve, automatic eliminate the pressure pipeline residual function head and pressure fluctuation flow deviation, no matter how changes in the system pressure, flow rate can be set to remain constant, effectively solve the disorder of water balance of network problems. When pressure pneumatic valve is used to support the user adjust themselves, differential pressure constant users, help stabilize the system operation, adjust the pressure switch can be used in the making of pneumatic valve. Pneumatic valve resistance of dynamic balance these functions ( Pressure/flow control pneumatic valve) The flow control, after the completion of a distribution flow system easy to adjust balance, effectively solve the disorder of water balance of network, can save more than %. The balance of pneumatic valve dynamic resistance function of dynamic resistance balance pneumatic valve has three functions: since the function of the flow pneumatic valve, manual balance function of pneumatic valve, pump three different operating modes of the conversion of self-reliance type pressure pneumatic valve function, respectively. Constant flow running time and self-reliance type flow control pneumatic valve function; Heat is mainly manual use the variable flow balancing functions of the pneumatic valve; Become a self management pressure, the user active variable flow operation, the function of the pneumatic valve. In order to avoid frequent replacement pneumatic valve heating pipe network, reducing heating costs. Balance the performance of the pneumatic valve and dynamic resistance characteristics. The pneumatic valve for double disc structure, unbalanced force is small, compact structure. 。 Users can automatic constant pressure, the absorption network of external pressure fluctuations, support the automatic adjustment control system. 。 Catheter tip control by the pneumatic valve installation, with functions of automatic eliminate congestion. 。 With mixed compression technology, stepless adjustable pressure control. 。 Pressure calibration accuracy, precision adjustment. 。 Because of external pressure main structure, easy to tear open outfit. 。 Copper pneumatic valve, pneumatic valve core as a whole. Dynamic resistance of the material and life balance a pneumatic valve, body: high quality grey cast iron; , corrosion resistant plastic body; , spring: stainless steel; Buried, wax: epdm fiber; , pneumatic valve: brass; , design life: years; Keywords:
