The fire valve is mainly composed of two parts: valve body and execution agency.
The valve body, including shells, flanges, leaves, and leaf linkage mechanisms.Among them, the valve body is usually made of high temperature -resistant materials such as cast iron and stainless steel. Its main role is to separate fire areas and non -fire areas to achieve fireproof isolation.As a key component in the fire valve, it will be covered on the valve body hole when the valve is closed to prevent fire flue gas and flames from entering non -fire areas.In addition, the spring in the fire valve is generally stainless steel spring, which is used to balance the pressure of the valve wedge when the pressure is closed, so that the valve can be closed steadily.
The executive parts include shells, blades regulators, clutches, temperature fuse, etc.Its working principle is to control the rotation of the blades through metal molten melting pieces and clutch mechanisms.When the temperature reaches the preset value, the metal molten melt will be melted, and the blade is turned off by the clutch mechanism to block the spread of fire and flue gas.
In general, the structural design of the fire prevention valve is delicate, and the work of each component can effectively play a role in fireproof isolation in the fire and protect the safety of non -fire areas.Please note that the specific structure of the fire prevention valve may be different due to the different manufacturers and uses. If you need to learn more, it is recommended to consult the relevant product manual or consult the professional fire equipment supplier.
