Products Description

Carbon steel tilting disc check valve is a commonly used valve type designed to control unidirectional fluid flow in pipelines. The name derives from its inclined disc design on the valve body.

This valve typically consists of three main components: the valve body, the disc, and the valve stem. The valve body serves as the primary structure with an inlet port and an outlet port, allowing fluid to enter through the inlet, pass through the disc-controlled mechanism, and exit via the outlet. The disc features an inclined circular design that smoothly opens or closes with fluid flow direction. The valve stem functions as the operating mechanism, typically controlled manually or automatically.

The working principle of carbon steel tilting disc check valve relies on the disc's free sliding under fluid pressure. When fluid flows in the same direction as the disc's inclined surface, hydraulic pressure pushes the disc open, enabling unrestricted passage through the valve body. Conversely, when fluid flows against the inclined surface, pressure resistance causes the disc to close, effectively preventing backflow.

Structural Features

‌Unique Tilting Disc Design‌: The disc is the core component, with its shape and installation angle meticulously engineered. The sealing surface between the disc and the seat achieves high conformity, ensuring effective sealing when closed and preventing medium leakage. Compared to the flap movement in traditional check valves, the disc's rotational motion is smoother, reducing water hammer effects during closure.
‌Spring-Assisted Mechanism‌: The integrated spring plays a critical role. Its preload can be adjusted according to operational conditions, ensuring precise opening and closing of the disc under varying flow rates and pressures. During backflow, the spring provides rapid restoring force, accelerating disc closure and improving valve responsiveness.
‌Compact Structural Layout‌: The overall design is space-efficient, offering greater installation flexibility in pipeline systems. This feature makes the tilting disc check valve suitable for both confined spaces in small-scale installations and extensive industrial pipeline networks, simplifying installation and configuration.
