Description

Technical Field

[0001] The invention relates to the technical field of valves, and in particular to an anti-shock wave valve based on modular design. Background Art

[0002] Anti-explosion wave valves are widely used in various ventilation systems. They are generally installed on the outer walls of the air inlet and outlet connected to the external environment. They can also be installed on the air duct at the location to be protected in the ventilation system to prevent shock wave airflow from entering the system and causing equipment damage and personal injury. The valve is widely used in petrochemical, nuclear engineering, large civil buildings, civil air defense projects and other fields.

[0003] Existing anti-explosion valves include gravity type and spring type.

[0004] The working principle of the gravity-type anti-explosion valve is that the valve plate relies on its own weight to open to maintain ventilation. When the shock wave comes, it pushes the valve plate to close; after the shock wave is released, the valve plate automatically opens. Since the valve plate is heavy and the response speed is slow, the protection effect is not ideal.

[0005] The valve plate of the spring-type anti-explosion wave valve is composed of multiple sets of parallel blades, each blade is driven by a shaft, the shaft runs through the side wall of the valve body, each shaft is linked by a connecting rod, and a spring is installed on the connecting rod. The function of the spring is to keep the valve plate in an open state. When the shock wave hits, the valve plate overcomes the spring force and closes. After the shock wave is released, the valve plate automatically opens under the action of the spring. Different springs need to be designed for valves of different specifications, and the requirements for springs are high. In addition, the spring is on the outside of the valve, which is easily affected by corrosion, foreign matter, etc., which reduces the valve performance. Affected by the weight and stroke of the valve plate, the response speed is slow, and the protection effect is not ideal. Therefore, an anti-shock wave valve based on modular design is needed to solve the above problems. Summary of the invention
