国标楔式闸阀
产品概述:
国标楔式闸阀广泛应用于石油、化工、火力发电厂等油品、水蒸气管路上做接通或截断管路中介质的启闭装置。
系列铸钢闸阀适用于公称压力PN1.6-42.0MPa(CL150-CL2500),工作温度-46—600℃的石油、化工、火力电站等各种工况的管路上,切断或接通管路介质。
其主要结构特点有:
1、产品结构合理、密封可靠、性能优良、造型美观。
2、密封面堆焊Co基硬质合金,耐磨、耐蚀、抗擦伤性能好、使用寿命长。
3、阀杆经调质及表面氮化处理,有良好的抗腐蚀性及抗擦伤性。
4、阀门设有倒密封结构,密封可靠。
5、零件材质及法兰、对焊端尺寸可根据实际工况或用户要求合理选配,满足各种工程需要。
产品特点:
1、结构紧凑、设计合理、阀门刚性好、通道流畅、流量系数小,
2、密封面采用不锈钢和硬质合金,使用寿命长,
3、采用柔性石墨填料、密封可靠、操作轻便灵活;
4、驱动方式为手动、气动、电动、齿轮传动、液动;
5、结构形式为弹性楔式单闸板、刚性楔式单闸板双闸板型式。
