金属密封蝶阀意味着双方of the seal pair are made of metal material or other hard materials. The sealing performance is poor, but it is resistant to high temperature, abrasion and good mechanical properties. Such as: steel + steel; steel + copper; steel + graphite; steel + alloy steel. The steel here may also be cast iron, cast steel, alloy steel or alloys for surfacing an...

有很多方法可以分类插头阀门。在本文中，我们将引入四种主要类型的插头阀门。1.润滑塞阀润滑塞阀借助于润滑剂（基础油和粘度改进）的帮助，该润滑剂（基础油和粘度改进剂）在塞子和主体座之间注射，以减少它们之间的摩擦。润滑的塞阀必须在几次循环后重新位密封。由于我......

如果在低温闸阀关闭后留在腔中的介质，则残留物将逐渐吸收空气中的热量并重新气化。气化后，它将剧烈扩展到600倍，并在阀门上产生极高的压力，称为“异常提升”。当发生不寻常的发生时，楔子将牢固地压在座位上，不能开阔......

Bronze and brass are two of the most common materials used to produce valves. This preference comes because both metals are quite malleable. They both are artificially made from natural metallurgical elements: brass is made from copper and zinc, while another is made primarily from copper and tin. Each metal offers valves numerous and various advantages...

有四种常见类型的塞阀，每个塞子具有特定的特性和优点。润滑塞阀润滑塞阀使用润滑剂来减少摩擦，并使每个端口紧密密封。润滑剂是基本上的基础油，增加了移动部件的粘度，例如无定形或熏蒸二氧化硅，它们在阀门插头表面和阀门中注入...

V型球阀是一个带金属座的单座球阀。调节性能是球阀中最好的，其流动特性是相等的百分比，可调率高达100：1。它在V形狭缝和金属座之间具有剪切动作，特别适用于含有纤维，微小固体颗粒和浆料的培养基。在此期间...
