In software engineering and system design, coupling refers to the degree of connection and dependency between different modules or components. The strength of coupling directly affects the maintainability, scalability and flexibility of the system. Usually, coupling is divided into the following three types:
Fire protection valves are a vital component of fire protection systems. They play a key role when a fire occurs. This article will delve into the definition, function, and importance of fire protection valves in fire safety. By understanding the working principles and application scenarios of these valves, we can better appreciate their value in protecting life and property safety.
Butterfly Valves are a type of valve widely used in pipeline systems. Its main feature is that its closing part (valve disc or butterfly plate) is disc-shaped, and the opening and closing functions are achieved by rotating around the valve axis. Butterfly valves mainly play the role of cutting off and throttling on pipelines.
Gate Valves are an important type of valve, which is mainly driven by the valve stem to move the opening and closing parts (gate) along the valve seat sealing surface.
Fire Protection Valves, or fire dampers, are an important part of the building fire protection system. They are usually installed on the ducts of ventilation and air conditioning systems, playing a key role in isolating fire and preventing the spread of smoke.
Firefighting systems typically utilize various types of valves to control the flow of water, foam, or other extinguishing agents. The specific types of valves used in a fire protection system depend on the system's design, purpose, and the substances it aims to control. Here are some common types of valves used in firefighting systems:
