锻钢法兰闸阀
锻钢法兰闸阀整体法兰端阀门有三种阀盖设计,第一种是螺栓型阀盖,通过凹凸面连接,采用不锈钢带与柔性石墨缠绕垫片,按需求也可采用环连接,第二种是焊接型阀盖,通过螺纹密封后焊接,按需求也可直接采用刚性焊接,第三种是自密封阀盖,通过螺纹与自密封阀盖连接。
整体法兰端阀门结构设计可用在闸阀、截止阀、立升式止回阀和旋启式止回阀。
一、闸阀的结构设计和规范:
锻钢闸阀制造按API 602,BS5352,ANSI B16.34.
试验与验收按API 598,标识按照MSS SP-25.
二、结构型式如下:
1.全通径或缩径
2.结构长度按ANSI/ASME B16.10
3.法兰按ANSI/ASME B16.5
4.自密封阀盖
5.明杆带支架
6.两端自动调整的填料压套;
7.本体倒密封
8.整体阀体法兰
9.对焊端按ANSI/ASME B16.25
10.环连接阀体阀盖垫片
11.用缠绕式垫片的螺栓型阀盖、螺纹密封、焊接型阀盖,或自密封阀盖
