電動偏心半球閥是在吸收消化國外的*技術(shù)而研發(fā)成功的新產(chǎn)品,也是*國內(nèi)閥門品種空白的創(chuàng)新產(chǎn)品,是在認真權(quán)衡球閥、蝶閥、閘閥等多種閥門優(yōu)缺點的前提下,借鑒德國類似產(chǎn)品而開發(fā)的全部國產(chǎn)化創(chuàng)新產(chǎn)品,應(yīng)用于石油、化工、電力和冶金等行業(yè),其核心技術(shù)屬國內(nèi)*,它設(shè)計*、結(jié)構(gòu)新穎。產(chǎn)品投放市場以來，受到顧客的首肯。

*：閥門結(jié)構(gòu)采用偏心契緊原理，通過傳動機構(gòu)達到閘緊、調(diào)節(jié)、關(guān)閉的目的，密封圈與球體都是金屬面環(huán)帶硬面接觸密封，雙偏心結(jié)構(gòu)閥門在開啟是球體藏于閥腔內(nèi)，流通載面大，且閥門不被沖刷，無流阻。關(guān)閉時閥芯不被沖刷，關(guān)閉時閥芯球面沿閥座漸進，具有剪切功能，有效得切除結(jié)垢障礙，實現(xiàn)可靠密封。它對容易結(jié)垢的介質(zhì)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(yīng)堆焊合金，經(jīng)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(guān)閉時再轉(zhuǎn)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(diào)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(jù)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(yè)部門。

電動偏心半球閥產(chǎn)品的主要用途及產(chǎn)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(yè)耐腐蝕、兩相混流介質(zhì)。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(chǎn)品結(jié)構(gòu)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(tài)、固態(tài)兩相混流或液態(tài)輸送化學反應(yīng)有結(jié)晶析分或結(jié)垢的工業(yè)管道輸送。產(chǎn)品結(jié)構(gòu)特點根據(jù)顧客所需介質(zhì)、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(tài)輸送管道的控制。產(chǎn)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。
