德國奧萊斯OLES進口大口徑鍛鋼球閥

【進口大口徑鍛鋼球閥】詳細說明：

鍛鋼球閥主要用于石油，天然氣的長距離管線輸送和城市煤氣管道系統(tǒng)．由于長輸管線用閥的*特征，因而在設計時充分考慮了其承受管道應力的能力，以及安全性，耐候性，*使用的可靠性密封設計結構等。驅動方式可選用手動、蝸輪、氣動、電動，連接方式可選用法蘭、焊接，結構形式為三段式，密封結構可選用軟密封、硬密封，壓力范圍PN1.0-32.0Mpa，公稱通徑為DN10-200mm，材質可選用鍛鋼、鍛不銹鋼。由于閥門的使用范圍非常的廣泛，同一種閥門在不同的場合與工況有不同的搭配。鍛鋼球閥是用帶有圓形通道的球體作啟閉件，球體隨閥桿轉動實現(xiàn)啟閉動作的閥門，既正向旋轉1/4圈（90°）時，閥關斷。反向旋轉1/4圈（90°）時，閥開啟。。球閥的啟閉件是一個有孔的球體，繞垂直于通道的軸線旋轉，從而達到啟閉通道的目的。球閥主要供開啟和關閉管道和設備介質之用。

Forged steel ball valves are mainly used in long-distance pipeline transportation of petroleum and natural gas and urban gas pipeline system. Due to the unique characteristics of long-distance pipeline valves, their ability to withstand pipeline stress, safety, weatherability, long-term reliability and sealing design structure are fully considered in the design. Manual drive mode, worm wheel, pneumatic and electric drive mode can be selected, flange and welding can be selected as connection mode, three-stage structure can be used, soft seal and hard seal can be selected as sealing structure, pressure range PN1.0-32.0 Mpa, nominal diameter DN10-200 mm, material can be used forged steel, forged stainless steel. Because of the wide application range of valves, the same valve has different matching in different situations and working conditions. Forged steel ball valve is a valve which uses a sphere with circular passage as the opening and closing part. The sphere rotates with the stem to realize the opening and closing action. When the sphere rotates 1/4 times (90 degrees) in the positive direction, the valve closes. When the reverse rotation is 1/4 turn (90 degree), the valve opens. The opening and closing part of the ball valve is a sphere with holes, which rotates around the axis perpendicular to the channel to achieve the purpose of opening and closing the channel. Ball valves are mainly used for opening and closing pipes and equipment media.

【進口大口徑鍛鋼球閥】特點：

1、所有部件均為鍛件

2、采用下裝式閥桿，設備倒密封結構

3、采用鑲嵌式閥座，閥座背后設備O型圈,確保介質不外漏

4、密封面采用尼龍或聚四氟乙烯，它的磨擦系數(shù)通常為巴氏合金的1/3，因此它是一種自然滑性材料。但抗彎曲強度和沖擊強度及較高的延性，與金屬不相上下。

鍛鋼浮動球閥產品特征

鍛鋼浮動球閥, 鍛造材料可以確保足夠的硬度和強度大額定操作壓力下沒有內在缺陷施放. 足量的壁厚度決定身體和適應不同的高強度螺栓閥系方便維護和足以承擔壓力管道閥門的閥內件精心設計, 選擇在各種工作可靠性的工作條件.

2.防火安全結構

當耳軸球閥正常使用,其加蓋閥座和球面法、閥座固定器o形環(huán)和蓋章的身體,這是軟密封,密封可靠當閥座和o形環(huán)受傷,閥座固定器和身體會加蓋膨脹石墨這樣的行為防火安全的目的.

3.防靜電設備

為了防止間的磨擦球,桿和聚四氟乙烯產生靜電可能點燃易燃物品和炸yao,導致事故,在這個球閥,靜態(tài)傳dao彈簧之間閥桿和球,閥桿和身體因此靜電是地面和系統(tǒng)安全進行擔保.

4.自由泄漏的身體密封結構

暢順,閥門的開關位置閥體和閥帽的雙加蓋墊片和o形環(huán),在此基礎上,這樣的原因似火、高溫、減震和凹凸不平的開放或關閉扭矩都不會引起外泄漏.

5.操作低扭矩

自我潤滑軸承安裝在摩擦的干細胞,導致耐磨、靈活的運作和低扭矩.

6.減輕自動閥體凹處

當身體壓力上升不正常的,如不穩(wěn)定因素、耳軸球閥下游閥座上將被正常壓力, 同時不正常的自動釋放壓力, 并不損壞密封的上游的座位
