Characteristics of 0.3 second fast closing valve

Characteristics of 0.3 second fast closing valve
1. The quick shutdown time can reach 0.3~0.5 seconds, and emergency shutdown is safe and reliable.
2. Triple eccentric metal sealing structure, easy and flexible opening and closing, zero leakage sealing.
3. At room temperature, a double eccentric soft seal structure can be used as the medium, which has low cost and reliable sealing.
4. Closing the valve end buffer effectively prevents valve inertia from hitting.
5. The 0.5-second quick closing valve can be achieved by using a spring or an accumulator, both of which are similar and equally safe and reliable.
Characteristics of 0.5-second electro-hydraulic linkage fast closing valve
1. The 0.5-second quick closing valve is mainly composed of a valve, a hydraulic station, a quick closing actuator, a PLC intelligent control box, and a specially designed stroke feedback device;
2. Precision machined gear rack hydraulic actuator, compact structure, smooth operation, safe and reliable;
3. PLC intelligent electrical control system, with high degree of automation, can remotely and locally control the system;
4. Adopting internationally renowned brand automation components, the product has superior performance and reliable quality;
5. The normal opening and closing power source of the 0.5-second fast closing valve is usually provided by the supporting hydraulic pump station, or it can come from the hydraulic station of the steam turbine main engine;
6. The system power supply is 380V, and the control power supply is AC220V, DC220V, DC110V, and other power levels;
7. The 0.5-second emergency quick cut-off valve adopts a three eccentric multi-level metal hard sealed butterfly valve, which is heat-resistant, flexible in opening and closing, easy to operate, and reliable in sealing
Application scope of quick closing valve
It is mainly used as an emergency shut-off valve in high safety level systems such as steam turbine exhaust pipelines, blast furnace gas residual pressure power generation devices (TRT), and industrial pipelines with media such as seawater, sewage, flue gas, air, and oil products.
