電動偏心半球閥是在吸收消化國外的*技術而研發成功的新產品,也是*國內閥門品種空白的創新產品,是在認真權衡球閥、蝶閥、閘閥等多種閥門優缺點的前提下,借鑒德國類似產品而開發的全部國產化創新產品,應用于石油、化工、電力和冶金等行業,其核心技術屬國內*,它設計*、結構新穎。產品投放市場以來，受到顧客的首肯。

*：閥門結構采用偏心契緊原理，通過傳動機構達到閘緊、調節、關閉的目的，密封圈與球體都是金屬面環帶硬面接觸密封，雙偏心結構閥門在開啟是球體藏于閥腔內，流通載面大，且閥門不被沖刷，無流阻。關閉時閥芯不被沖刷，關閉時閥芯球面沿閥座漸進，具有剪切功能，有效得切除結垢障礙，實現可靠密封。它對容易結垢的介質輸送特別有效。

第二：閥門與半球采用雙金屬，在球體上堆焊不用的合金，閥座也作相應堆焊合金，經特殊的處理，密封面組合成防腐、耐磨、耐高溫等各種類型，滿足不同場合需求。

第三：密封嚴緊，輸送有害氣體可達到零泄露。

第四：閥座與球體保留有補償量，當閥座磨損后，關閉時再轉動少許，仍能可靠密封，延長使用壽命，此外，用戶將一壓板螺栓擰掉，從新調整或更換后閥座仍可用，避免了眾多閥門密封失效整臺報廢的弊端。

根據用戶需要堆焊不同的合金，雙金屬密封圈的選配可以用于耐磨、耐腐蝕、耐高溫等而又要求嚴格密封的不同工業部門。

電動偏心半球閥產品的主要用途及產品特點

1、通用閥：適用于污水處理、紙漿、氧化鋁、城市采暖供熱要求嚴緊的場合。

2、油化工閥：適用于原油，重油等各類油品、化工行業耐腐蝕、兩相混流介質。耐溫可達425℃。

3、燃氣閥：適用于煤氣、天然氣、液化氣的輸送控制。產品結構特點是在密封圈堆焊閥不同含鉻合金，密封嚴緊、抗腐蝕。

4、料漿閥：適用于液態、固態兩相混流或液態輸送化學反應有結晶析分或結垢的工業管道輸送。產品結構特點根據顧客所需介質、溫度要求不同，球體受用鉻鉬、釩合金堆焊，閥座采用鉻、鉬合金、鉻合金、不銹鋼合金焊條堆焊滿足不同料漿輸送的需要。

5、煤粉灰渣閥：適用于電廠、水力除渣或氣態輸送管道的控制。產品要求耐磨性能，球體采用組合球式雙金屬，具有相當高的剛度并非常耐磨。閥座采用整體耐磨鋼或全堆焊。
