在工業(yè)閥門家族中，蝶閥是“以小博大”的代表——它結(jié)構(gòu)非常簡單、體積非常小、重量非常輕，卻能在大口徑管道中實現(xiàn)快速啟閉和流量調(diào)節(jié)。良工閥門集團的蝶閥產(chǎn)品線覆蓋了從普通給排水到1200℃超高溫的出彩端工況。

In the industrial valve family, butterfly valve is the representative of "small wins big" - it has the simplest structure, smallest volume, and lightest weight, but can achieve fast opening and closing and flow regulation in large-diameter pipelines. The butterfly valve product line of Lianggong Valve Group covers extreme working conditions from ordinary water supply and drainage to 1200 ℃ ultra-high temperature.

一、蝶閥的工作原理與結(jié)構(gòu)優(yōu)勢

1、 The working principle and structural advantages of butterfly valves

蝶閥的啟閉件是一個圓盤形的蝶板，圍繞閥桿旋轉(zhuǎn)90°即可實現(xiàn)管道的開啟和關(guān)閉。蝶閥的“四兩撥千斤”體現(xiàn)在：

The opening and closing component of a butterfly valve is a disc-shaped butterfly plate that can be rotated 90 ° around the valve stem to open and close the pipeline. The "four two turns per kilogram" of butterfly valves is reflected in:

結(jié)構(gòu)簡單、體積小、重量輕——蝶閥在所有閥門中結(jié)構(gòu)非常簡單，安裝尺寸非常小。

Simple structure, small size, and light weight - Butterfly valves have the simplest structure and smallest installation size among all valves.

啟閉迅速——90°旋轉(zhuǎn)即可完成全開或全關(guān)，操作時間僅需幾秒鐘。

Quick opening and closing -90 ° rotation can complete full opening or full closing, and the operation time only takes a few seconds.

良好的關(guān)閉密封和流量調(diào)節(jié)功能——蝶閥不僅可用于通斷，還可用于流量調(diào)節(jié)。

Good sealing and flow regulation function - Butterfly valves can be used not only for on-off, but also for flow regulation.

二、良工蝶閥的主流產(chǎn)品系列

2、 The mainstream product series of Lianggong butterfly valve

軟密封蝶閥——閥座為橡膠或聚四氟乙烯材質(zhì)，密封性能優(yōu)異，適用于給排水、水處理等低壓工況。

Soft sealed butterfly valve - the valve seat is made of rubber or polytetrafluoroethylene material, with excellent sealing performance, suitable for low-pressure conditions such as water supply and drainage, water treatment, etc.

硬密封蝶閥——閥座為金屬材質(zhì)，適用于高溫、高壓、腐蝕性介質(zhì)。

Hard sealed butterfly valve - The valve seat is made of metal material and is suitable for high temperature, high pressure, and corrosive media.

對夾式蝶閥——結(jié)構(gòu)非常緊湊，通過螺栓夾緊在管道法蘭之間。

Clamp on butterfly valve - the most compact structure, clamped between pipeline flanges with bolts.

法蘭式蝶閥——通過法蘭與管道連接，安裝可靠。

Flange butterfly valve - connected to the pipeline through a flange, installed reliably.

液控蝶閥——通過液壓系統(tǒng)控制蝶板動作，適用于大口徑、高壓力工況。

Hydraulic butterfly valve - controlled by a hydraulic system to control the movement of the butterfly plate, suitable for large-diameter and high-pressure working conditions.

1200℃超高溫蝶閥——良工的拳頭產(chǎn)品之一，可在1200℃的出彩端溫度下工作。

1200 ℃ ultra-high temperature butterfly valve - one of Lianggong's flagship products, capable of working at extreme temperatures of 1200 ℃.

三偏心多層次金屬硬密封蝶閥——精密的彈性密封圈和三偏心結(jié)構(gòu)設(shè)計，被廣泛用于介質(zhì)溫度≤425℃的冶金、電力、石油化工、給排水和市政建設(shè)等工業(yè)管道。

Triple eccentric multi-level metal hard sealed butterfly valve - precision elastic sealing ring and triple eccentric structure design, widely used in industrial pipelines such as metallurgy, power, petrochemical, water supply and drainage, and municipal construction with medium temperature ≤ 425 ℃.

三、蝶閥選型的核心技術(shù)參數(shù)

3、 Core technical parameters for butterfly valve selection

1. 工作溫度——常溫、高溫、低溫對密封材質(zhì)有不同要求。

1. Working temperature - Normal temperature, high temperature, and low temperature have different requirements for sealing materials.

2. 工作壓力——軟密封蝶閥一般適用于中低壓，硬密封蝶閥可適用于高壓。

2. Working pressure - Soft sealed butterfly valves are generally suitable for medium and low pressure, while hard sealed butterfly valves can be suitable for high pressure.

3. 密封要求——需零泄漏的場合選用軟密封，耐高溫的場合選用硬密封。

3. Sealing requirements - Soft seals should be used in situations where zero leakage is required, and hard seals should be used in situations where high temperature resistance is required.

4. 操作方式——手動、渦輪、電動、氣動、液動等多種驅(qū)動方式可選。

4. Operation mode - Multiple driving modes are available, including manual, turbo, electric, pneumatic, hydraulic, etc.

5. 連接方式——對夾式、法蘭式、焊接式等。

5. Connection methods - clamp type, flange type, welding type, etc.

四、蝶閥的典型應用場景

4、 Typical application scenarios of butterfly valves

良工蝶閥廣泛應用于給排水、市政建設(shè)、電力、石油化工、冶金等行業(yè)。在給排水領(lǐng)域，軟密封蝶閥是主流選擇。在電廠脫硫系統(tǒng)中，耐腐蝕蝶閥是關(guān)鍵設(shè)備。在超高溫工況下，良工的1200℃超高溫蝶閥是少有的可靠選擇。從城市供水到高溫冶金，從脫硫脫硝到核電軍工，良工蝶閥以“小身材”承載著“大作為”。

Lianggong butterfly valves are widely used in industries such as water supply and drainage, municipal construction, power, petrochemicals, metallurgy, etc. In the field of water supply and drainage, soft sealed butterfly valves are the mainstream choice. In the desulfurization system of power plants, corrosion-resistant butterfly valves are key equipment. Under ultra-high temperature conditions, Lianggong's 1200 ℃ ultra-high temperature butterfly valve is a rare and reliable choice. From urban water supply to high-temperature metallurgy, from desulfurization and denitrification to nuclear power and military industry, Lianggong butterfly valves carry great achievements with their small size.
