止回閥，作為一種重要的流體控制設備，其核心功能是防止流體在特定方向上倒流。這種閥門利用其獨特的結構，確保流體只能沿一個方向通過，從而有效地保護了管道系統和設備免受逆向流體的沖擊。止回閥廣泛應用于各種工業領域，如化工、石油、制藥等，確保了流體輸送的安全與穩定。

Check valve, as an important fluid control device, its core function is to prevent fluid from flowing back in a specific direction. This valve utilizes its unique structure to ensure that fluid can only pass in one direction, effectively protecting pipeline systems and equipment from the impact of reverse fluid. Check valves are widely used in various industrial fields, such as chemical, petroleum, pharmaceutical, etc., to ensure the safety and stability of fluid transportation.

工作原理：

Working principle:

止回閥通過介質流動的壓力來自動開關，從而實現防止介質倒流的功能。

The check valve automatically opens and closes based on the pressure of the medium flow, thereby preventing the backflow of the medium.

特點：

Characteristics:

這種閥門常被用于管道系統，以防止回流現象的發生，且操作簡便，結構緊湊。

This type of valve is often used in pipeline systems to prevent backflow, and is easy to operate with a compact structure.

應用場景：

Application scenarios:

止回閥在許多場景中都有廣泛的應用，例如水泵的出口、排水系統等，確保流體只能沿一個方向流動。

Check valves are widely used in many scenarios, such as the outlet of water pumps, drainage systems, etc., to ensure that fluid can only flow in one direction.

安全閥是一種重要的安全裝置，廣泛應用于各種設備和管道系統中。其工作原理是基于系統壓力的變化來自動啟閉，旨在保護設備和管道免受過壓損傷。安全閥具有結構簡單、操作可靠等特點，是工業安全領域不可或缺的一部分。

Safety valve is an important safety device widely used in various equipment and pipeline systems. Its working principle is based on the change of system pressure to automatically open and close, aiming to protect equipment and pipelines from overpressure damage. Safety valves have the characteristics of simple structure and reliable operation, and are an indispensable part of the industrial safety field.

工作原理詳解：

Detailed explanation of working principle:

一旦系統內的壓力超越了預設的限制，安全閥便會自動啟動，釋放過高的壓力，確保系統壓力維持在安全范圍內。當壓力恢復正常后，閥門又會自動關閉，從而實現對設備和系統的有效保護。

Once the pressure inside the system exceeds the preset limit, the safety valve will automatically activate to release the excessive pressure and ensure that the system pressure is maintained within a safe range. After the pressure returns to normal, the valve will automatically close again, thereby achieving effective protection for the equipment and system.

特點概覽：

Overview of Characteristics:

安全閥以其高靈敏度著稱，能夠迅速而自動地響應系統壓力的變化。其核心作用是防止系統壓力超過設定值，從而確保設備的安全運行。

Safety valves are known for their high sensitivity and can quickly and automatically respond to changes in system pressure. Its core function is to prevent the system pressure from exceeding the set value, thereby ensuring the safe operation of the equipment.

應用領域廣泛：

Widely applicable fields:

安全閥是鍋爐、壓力容器、管道系統等眾多設備過壓保護的重要選擇。其重要性不言而喻，是工業安全領域中不可或缺的一環。

Safety valves are an important choice for overpressure protection of many equipment such as boilers, pressure vessels, and pipeline systems. Its importance is self-evident and it is an indispensable part of the field of industrial safety.
