Description

Technical Field

[0001] The utility model relates to the technical field of valves, in particular to a valve with a multi-channel structure. Background Art

[0002] A valve is a mechanical device used to control the flow of fluids. It precisely controls the flow rate, pressure, and direction of fluids by opening, regulating, or closing the fluid passageway. Valves generally consist of a valve body, seat, valve core, handle, or actuator, and are widely used in industries such as petroleum, chemical, electric power, water treatment, and HVAC. Valves can be categorized into various types based on their operating principle and structure, including globe valves, ball valves, gate valves, and regulating valves. The proper selection and use of valves is crucial to ensuring the safety and efficiency of process flows.

[0003] Multi-channel valves are capable of controlling multiple fluid channels simultaneously. Their design allows for the switching and distribution of multiple fluids within a single valve body. These valves are often used in complex fluid systems, effectively simplifying piping layouts and reducing connection points, thereby improving overall system reliability and compactness. Common multi-channel valves include multi-way valves and reversing valves, and are widely used in the chemical, petroleum, pharmaceutical, and HVAC industries.
