RSIND hydraulic pipeline explosion-proof valve (also known as RSIND explosion-proof crack valve or safety valve) is an important safety device in hydraulic systems. Its main function is to quickly cut off the oil circuit or release pressure when the pipeline suddenly ruptures or the pressure rises abnormally, in order to prevent system loss of control, equipment damage, or personnel injury. The following is a detailed explanation of its specific function and working principle: --- ### **1. Main function** -* * Prevent loss of control in case of pipeline rupture** When the hydraulic hose or joint suddenly ruptures, the explosion-proof valve can automatically close the oil circuit in an instant, preventing a large amount of hydraulic oil leakage and avoiding the actuator (such as hydraulic cylinder, motor) from accidentally falling or losing control due to pressure loss, ensuring equipment stability. -* * Protect load safety** In applications such as lifting and hoisting (such as construction machinery and lifting platforms), if the pipeline ruptures, the explosion-proof valve can lock the oil in the cylinder to prevent the load from falling and ensure the safety of personnel and equipment. -* * Avoid pressure shock (water hammer effect)** In high-pressure systems, sudden valve closure or emergency stop of the actuator may generate pressure shock waves. Explosion proof valves can alleviate impact and protect pipelines and components from damage through their pressure relief function. -* * Prevent system overload** Some explosion-proof valves also have the function of overflow valves. When the pressure exceeds the set value, they automatically open to release pressure, avoiding damage to components such as pumps and valves due to overload. --- ### **2. Working principle** -One way cut-off RSIND explosion-proof valve** It is usually composed of a valve core, a spring, and an induction mechanism. During normal operation, the forward flow of oil remains open; When the flow rate increases abnormally (such as tube bursting), the valve core quickly closes under pressure difference or spring action, blocking the oil circuit. -Overflow explosion-proof valve** When the pressure exceeds the set threshold, the valve core opens and guides excess oil back to the tank. After the pressure returns to normal, it automatically closes. --- ### **3. Typical application scenarios** -* * Construction Machinery * *: The inlet and outlet oil circuits of hydraulic cylinders for excavators and crane booms. -Aerospace: Landing gear, servo hydraulic system. -Industrial equipment: hydraulic lifting platform, injection molding machine, metallurgical equipment. -Mobile devices: agricultural machinery, fire ladders. --- ### **4. Difference from ordinary safety valves** -* * Response speed * *: Explosion proof valves are designed for sudden pipe bursts, and the action time is usually in milliseconds, which is faster than conventional safety valves. -* * Function focus * *: Ordinary safety valves are mainly used to regulate system pressure, while explosion-proof valves focus more on quickly isolating faulty sections. --- ### **5. Selection precautions** -Pressure level: It is necessary to match the system working pressure and burst pressure. -Flow requirements: Select valve specifications based on pipeline diameter and flow rate. -* * Installation location * *: Usually near the actuator or vulnerable pipe section. --- ###* * Summary** The RSIND hydraulic explosion-proof valve is the "last line of defense" for system safety, effectively avoiding catastrophic accidents by quickly responding to abnormal pressure or flow changes, and is particularly critical in high-pressure, heavy-duty, or mobile equipment. Its design and selection need to be combined with specific working conditions to ensure reliability and response speed.
