How does a Hose burst valves prevent the outlet flow of the cylinder from continuing to flow after a hose breaks?

A Hose burst valves is a key safety component in a hydraulic system, designed to respond to emergencies when a hose breaks unexpectedly. Under normal operating conditions, the valve allows fluid to flow freely in both directions within the hose without causing any obstruction to the operation of the hydraulic system. This ensures that the system can perform its intended functions efficiently and smoothly.
However, once a hose breaks due to aging, excessive wear, external damage or other reasons, the situation will change immediately. The Hose burst valves is equipped with a precision-designed plate structure inside, which is in standby mode when the hose is intact and will not cause any impact on the normal operation of the system.
But when a hose break occurs, the plate structure will respond quickly. Its response mechanism may rely on changes in hydraulic pressure, the action of a physical trigger, or other advanced sensing and control systems. Once triggered, the plate structure immediately engages tightly with the main body of the valve to form a reliable seal.
This sealing action is critical because it effectively cuts off the outlet flow path from the cylinder. Before the hose broke, this part of the flow was delivered to other parts of the system through the hose. But after the break occurs, without the prompt intervention of the Hose burst valves, this part of the flow may leak out uncontrollably, causing system pressure to drop, load loss, and even more serious safety accidents.
But with the protection of the Hose burst valves, the situation is completely different. Once the valve is closed, it forms a solid barrier to prevent the continued flow of the cylinder outlet flow. This not only prevents the leakage of hydraulic oil, but also ensures that the load can be safely locked in its current position. This is crucial to protecting the safety of operators, preventing equipment damage, and maintaining the overall stability of the hydraulic system.
