不銹鋼蝶閥如何在管道中使用?

由于不銹鋼蝶閥在管路中的壓力損失比較大,大約是閘閥的三倍,因此在選擇不銹鋼蝶閥時,應充分考慮管路系統(tǒng)受壓力損失的影響,還應考慮關閉時蝶板承受管道介質壓力的堅固性。此外,還需要考慮在高溫下彈性閥座材料所承受工作溫度的限制。不銹鋼蝶閥的結構長度和總體高度較小,開啟和關閉速度快,且具有良好的流體控制特性,不銹鋼蝶閥的結構原理適合制作大口徑閥門。當要求不銹鋼蝶閥作控制流量使用時,重要的是正確選擇不銹鋼蝶閥的尺寸和類型,使之能恰當?shù)?、有效地工作。通常,在?jié)流、調節(jié)控制與泥漿介質中,要求結構長度短,啟閉速度快(1/4轉)。低壓截止(壓差小),推薦選用不銹鋼蝶閥。
Because the pressure loss of the stainless steel butterfly valve in the pipeline is relatively large, about three times that of the gate valve, when selecting the stainless steel butterfly valve, the impact of the pressure loss on the pipeline system should be fully considered, and the robustness of the butterfly plate under the pressure of the pipeline medium should also be considered when closing. In addition, it is also necessary to consider the limit of the working temperature of the resilient seat material under high temperature. The structural length and overall height of stainless steel butterfly valve are small, the opening and closing speed is fast, and it has good fluid control characteristics. The structural principle of stainless steel butterfly valve is suitable for making large-diameter valves. When stainless steel butterfly valve is required to be used for flow control, it is important to correctly select the size and type of stainless steel butterfly valve so that it can work properly and effectively. Generally, in throttling, regulating control and mud medium, short structure length and fast opening and closing speed (1/4 turn) are required. Stainless steel butterfly valve is recommended for low pressure cut-off (low differential pressure).
在雙位調節(jié)、縮口地通道、低噪聲、有氣穴和氣化現(xiàn)象,向大氣少量滲漏,具有磨蝕性介質時,可以選用不銹鋼蝶閥。在特殊工況條件下節(jié)流調節(jié),或要求密封嚴格,或磨損嚴重、低溫(深冷)等工況條件下使用不銹鋼蝶閥時,需使用特殊設計金屬密封帶調節(jié)裝置地三偏心或雙偏心地專用不銹鋼蝶閥。中線不銹鋼蝶閥適用于要求達到完全密封、氣體試驗泄漏為零、壽命要求較高、工作溫度在-10℃~150℃的淡水、污水、海水、鹽水、蒸汽、天然氣、食品、藥品、油品和各種酸堿及其他管路上。
Stainless steel butterfly valves can be used in the case of two-position regulation, necked channel, low noise, cavitation and gasification, small leakage to the atmosphere, and abrasive media. When the stainless steel butterfly valve is used under special working conditions, such as throttling adjustment, strict sealing, severe wear, low temperature (deep cold) and other working conditions, the special stainless steel butterfly valve with special design metal sealing belt adjustment device, three-eccentric or double-eccentric, shall be used. The center line stainless steel butterfly valve is applicable to fresh water, sewage, sea water, brine, steam, natural gas, food, medicine, oil, various acids and alkalis and other pipelines that require complete sealing, zero leakage in gas test, high service life, and operating temperature between - 10 ℃ and 150 ℃.

軟密封偏心不銹鋼蝶閥適用于通風除塵管路的雙向啟閉及調節(jié),廣泛用于冶金、輕工、電力、石油化工系統(tǒng)的煤氣管道及水道等。金屬對金屬線密封雙偏心不銹鋼蝶閥適用于城市供熱、供氣、供水等煤氣、油品、酸堿等管路,作為調節(jié)和節(jié)流裝置。金屬對金屬面密封三偏心不銹鋼蝶閥除作為大型變壓吸附(PSA)氣體分離裝置程序控制閥使用外,還可廣泛用于石油、石化、化工、冶金、電力等領域,是閘閥、截止閥的良好替代產(chǎn)品。
The soft seal eccentric stainless steel butterfly valve is applicable to the two-way opening and closing and adjustment of the ventilation and dust removal pipeline, and is widely used in the gas pipeline and water channel of metallurgy, light industry, electric power, petrochemical system, etc. The metal-to-metal line sealed double-eccentric stainless steel butterfly valve is applicable to urban heating, gas supply, water supply and other gas, oil, acid and alkali pipelines as a regulating and throttling device. In addition to being used as the program control valve of large pressure swing adsorption (PSA) gas separation device, metal-to-metal sealing tri-eccentric stainless steel butterfly valve can also be widely used in petroleum, petrochemical, chemical, metallurgy, power and other fields, and is a good substitute for gate valve and stop valve.
