前言:我們北方閥門集團(tuán)有限公司是坐落在山東濰坊的閥門生產(chǎn)廠家,除了一會要討論的大口徑閥門,大口徑三偏心蝶閥,我們公司還生產(chǎn)、銷售各種規(guī)格的球閥、閘閥、蝶閥、截止閥等全品類工業(yè)閥門,將100%符合標(biāo)準(zhǔn),100%保證質(zhì)量,100%讓您滿意,我們的服務(wù)“一切為了客戶”。

大口徑蝶閥廠家北方閥門集團(tuán)技術(shù)部整理,三偏心大口徑蝶閥從發(fā)明到現(xiàn)在已經(jīng)有50多年的歷史了,在這50多年中,人們也在不斷地對三偏心大口徑蝶閥進(jìn)行改良,這也使得三偏心大口徑蝶閥的應(yīng)用領(lǐng)域變得更寬廣。原來三偏心大口徑蝶閥只用于水介質(zhì)的截斷和聯(lián)通,三偏心的設(shè)計增強(qiáng)大口徑蝶閥的功能,已經(jīng)成為工業(yè)工業(yè)管道設(shè)備中,關(guān)鍵工藝環(huán)境最惡劣的條件下性能卓越的大口徑閥門之一。

The triple-eccentric large-diameter butterfly valve has a history of more than 50 years since its invention. In the past 50 years, people are constantly improving the triple-eccentric large-diameter butterfly valve, which also makes the application of the triple-eccentric large-diameter butterfly valve. The field becomes wider. The original triple-eccentric large-diameter butterfly valve is only used for the cut-off and communication of water medium. The triple-eccentric design enhances the function of the large-diameter butterfly valve, and has become a large-diameter valve with excellent performance in the most severe conditions of the key process environment in industrial industrial pipeline equipment. one.

三偏心大口徑蝶閥,正如其名稱所指,三個獨(dú)立的偏移被設(shè)計成了大口徑閥門。具體是指:

1)盤/閥座密封面的中心線,

2)軸相對于孔的中心線的位置;

3)從閥孔的中心線偏移的閥座錐角的軸線。

這三個偏移的組合提供了一個錐形的密封面,最大限度地減少三偏心大口徑蝶閥閥座和密封件之間的磨損,提高三偏心大口徑蝶閥的使用壽命和密封性。此外,把優(yōu)閥座面降低到最小,降低三偏心大口徑蝶閥的工作轉(zhuǎn)矩。

Triple Offset Large Diameter Butterfly Valves, as the name suggests, three independent offsets are designed to be large diameter valves. Specifically:

1) The centerline of the disc/seat sealing surface,

2) The position of the shaft relative to the centerline of the hole;

3) The axis of the seat cone angle offset from the centerline of the valve bore.

The combination of these three offsets provides a conical sealing surface that minimizes wear between the seat and the seal, improving the service life and tightness of the butterfly valve. In addition, the optimal valve seat surface is reduced to a minimum, and the working torque of the triple eccentric large-diameter butterfly valve is reduced.

一般來說,由于三偏心大口徑蝶閥密封特性以及成本比其他金屬閥座大口徑閥門類型選擇更有優(yōu)越性。由于結(jié)構(gòu)緊湊,回轉(zhuǎn)的設(shè)計和輕質(zhì)結(jié)構(gòu),可以安裝和操作方便,他們不需要管支撐?筛鼡Q的密封環(huán),允許快速和簡單的維修和低扭矩(允許較小的驅(qū)動器)意味著更節(jié)省成本。

雙向零泄漏封閉的金屬座只有一次軟閥座大口徑閥門。這將極大地擴(kuò)展應(yīng)用的可能性。靈活的密封環(huán)和最佳的扭矩傳輸,這意味著這些大口徑閥門可以提供消防安全設(shè)計和密封性能,可以大于一般大口徑蝶閥設(shè)計的最大溫度范圍。 傳統(tǒng)上,可能會發(fā)現(xiàn)在眾多行業(yè)生成石油和天然氣加工、煉油、化工和石化廠、發(fā)電、海上平臺、供熱、造紙、鋼米爾斯、糖米爾斯、海水淡化、水處理和分配。他們在所有行業(yè)中的使用增加了嚴(yán)格的政府法規(guī)和更大的生產(chǎn)需求迫使用戶尋求解決方案。用量也節(jié)節(jié)攀升,已經(jīng)存在了數(shù)十年,特點提供了許多好的解決方案,包括那些具有更大的挑戰(zhàn)。這些好處包括運(yùn)營效率,耐磨料介質(zhì)和化學(xué)品到一定的溫度或壓力,并在眾多的操作條件的多功能性。

Generally speaking, due to the sealing characteristics and cost of the triple eccentric large-diameter valve, the butterfly valve is more advantageous than other metal-seat large-diameter valve types. Due to their compact, swivel design and lightweight construction, they can be easily installed and operated, and they do not require tube support. Replaceable seal rings, allowing quick and easy repairs and low torque (allowing for smaller drives) mean more cost savings.

Two-way zero-leakage closed metal seat only has a soft seat large-diameter valve. This will greatly expand the application possibilities. Flexible sealing rings and optimal torque transmission mean that these large diameter valves can provide fire safety design and sealing performance that can be larger than the maximum temperature range of general large diameter butterfly valve designs. Traditionally, it may be found in numerous industries generating oil and gas processing, refining, chemical and petrochemical plants, power generation, offshore platforms, heating, paper, steel mills, sugar mills, desalination, water treatment and distribution. Their use in all industries has increased stringent government regulations and greater production demands forcing users to seek solutions. Usage is also climbing, and features have been around for decades, offering many good solutions, including those with greater challenges. These benefits include operational efficiency, wear media and chemicals to a certain temperature or pressure, and versatility in numerous operating conditions.

利用設(shè)計的特點,下一代設(shè)計提供的功能,進(jìn)一步提高三偏心大口徑蝶閥的安全性和性能,-包括:

1、采用精密機(jī)加工的密封面和密封環(huán)形成金屬對金屬密封。即使在高溫高壓以及其他的嚴(yán)苛的服務(wù)環(huán)境,都可以做到雙向密封零泄漏。低摩擦和流線形的標(biāo)準(zhǔn)標(biāo)準(zhǔn)直角圓錐設(shè)計,金屬對金屬能很好的解決熱脹冷縮,是在高溫高壓環(huán)境服務(wù)的重要特征。金屬對金屬密封允許應(yīng)用在有防火要求的油田中。

2、最佳的閥座密封面設(shè)計,閥座密封面采用在大口徑閥門本體上堆焊司太立硬質(zhì)合金,使用密封面有更長的壽命和更好的耐磨性,即使反復(fù)循環(huán)使用。這種密封結(jié)構(gòu)設(shè)計減少了和蝶板的摩擦,減少了工作扭矩。

3、特殊的閥座設(shè)計使用大口徑閥門可以自動調(diào)整大口徑閥門的密封。浮動的密封環(huán)和一個寬的密封環(huán)支撐墊片,使用密封性和啟閉更加可靠。這種閥座確保大口徑閥門有雙向密封特性。

4、大口徑閥門的設(shè)計的定位銷在蝶板很低的位置,允許在熱膨脹時都有良好的性能,最大程度的減小閥桿的擾度。因此,大口徑閥門有很長的使用壽命。

Taking advantage of the design features, the next generation design offers features that further enhance the safety and performance of triple offset large diameter butterfly valves, including:

1. Using precision machined sealing surface and sealing ring to form metal-to-metal seal. Even in high temperature and high pressure and other harsh service environments, two-way sealing and zero leakage can be achieved. Standard standard right-angle cone design with low friction and streamline shape, metal-to-metal can well solve thermal expansion and contraction, which is an important feature of service in high temperature and high pressure environment. Metal-to-metal sealing allows applications in oil fields where fire protection is required.

2. The best valve seat sealing surface design, the valve seat sealing surface is made of stellite hard alloy surfacing on the large-diameter valve body, the use of the sealing surface has a longer life and better wear resistance, even if repeated cycles use. This sealing structure design reduces the friction with the disc and reduces the working torque.

3. The special valve seat design can automatically adjust the sealing of large-diameter valves by using large-diameter valves. The floating seal ring and a wide seal ring support gasket make the use of tightness and opening and closing more reliable. This seat ensures bi-directional sealing for large diameter valves.

4. The large-diameter valve is designed with a positioning pin at a very low position on the disc, which allows good performance during thermal expansion and minimizes the disturbance of the valve stem. Therefore, large-diameter valves have a long service life.
