产品概述
◆概述
铸件壳体H76型凸耳对夹双瓣旋启式止回阀安装在管路系统,其主要作用是防止升质倒流,止回阀是一种依靠介质压力开启和关闭的自动阀门。
我公司针对传统结构止回阀存在的问题,以美国AP1标准和德国DIN标准为依据.结合我公司多年来在阀门试验研究、开发设计、加工制造等方面的丰富经验,研制开发了H76型凸耳对娈、常规对夹双瓣旋启式止回阍,H74型对夹单瓣旋启式止回阀和H71ly!对夹升降式止回阀系列产品,经石化、冶金、电力、轻工、食品等行业的企业和设备配套厂家多年使用,效果良好,深受用户好评。
◆用途
铸件壳体H76型凸耳对夹双瓣旋启式止回阀适用于公称压力PNl.OMpa一42.0Mpa、Class150-2500、NPSl/2 - 48.工作温度-196 - 5400℃的各种管路上,用于防止介质倒流。通过选用不同的材质,可适用于水、蒸汽、油品、硝酸、醋酸、强氧化性介质及尿素等多种介质。
