EDTVD dynamic equilibrium electric valves Shanghai Tianjin Shield

Dynamic balance of electric two-way valve Description: Model: EDTVD Material: Brass Synonyms: dynamic balance of electric two-way valve connection: thread I homeostasis electric two-way valve is different from the traditional electric control valve of the new generation of products It is a dynamic equilibrium with the electric valve integrated products. In the system load fluctuations of variable flow systems, when the system pressure changes, the dynamic balance of electric two-way valve second end of the pressure difference (P1-P3) also changes: ⑴, when the inlet pressure P1 increases, (P1 -P2) increases, then the electric valve spool upward movement, so that P1, P2 between reducing the opening degree of the valve body reduces pressure P2; P1 when the inlet pressure reduced, (P1-P2) decreases, then the electric valve downward movement of the core, so that P1, P2 between the opening increases, the spool pressure P2 increases. Therefore, the pressure no matter how the system changes, through regulation of the electric valve spool, P2, and P3 pressure is always maintained. Therefore, this valve anti-jamming capability is strong, with a dynamic equilibrium function; ⑵, when the straight travel electric actuator receives a control signal to the valve shaft extension of A-B to move up and down (or rotary electric actuator receives a control signal to the valve shaft Yan R rotation), the opening of the P2, P3 also changes between. Because regardless of system pressure (P1-P3) what changes, P2, P3 pressure difference between (P2-P3) is always the same, and therefore correspond to any open position, the water flow is certain of its transportation and electric The actual valve flow characteristic curve from its ideal flow characteristic curve is the same, there is no deviation. Therefore, this more traditional electric control valve electric control valve has a better regulation characteristics. Dynamic balance of electric two-way valve is mainly used for water fan coil air conditioning system is controlled. Products from the valve body, composed of bile and electric actuators. It is mainly applied to HVAC systems of fan coil temperature control. In the system load fluctuations of variable flow systems have obvious advantages, such as high-rise hotels and office buildings, air-conditioning systems. Features: 1, the product is equipped Yaris pressure compensated flow control valve function. When an official network pressure changes, the pressure by the ticket compensation, self-sustaining constant by adjusting the flow control valve, so that affect the flow from the system pressure fluctuations. The product also has to accept the room thermostat signal to implement an on / off two regulation. 2. The product has been tested and has had slightly expensive homeostasis characteristics in the operating pressure control, flow rate fluctuation error value at + 5%. 3. The thermostat can be used with all brands supporting water for fan coil control. 4. Valve Co., Ltd. Shanghai, Tianjin Shield welcome your inquiry to discuss!
