RETZ瑞茨『进口法兰截止阀』详细介绍●RETZ截止阀系列●RETZ法兰截止阀●产品数据
?进口法兰截止阀描述--
RETZ法兰截止阀的启闭件是盖形的阀瓣，密封面呈平面,阀瓣沿阀座的中心线作直线运动来达到启闭。
RETZ The opening and closing part of the flange stop valve is a cap valve with a cover shape. The sealing surface is plane, and the valve flap moves along a straight line along the center line of the valve seat to achieve the opening and closing.
?进口法兰截止阀特征--
1.寿命长-蒸汽截止阀采用独特的双波纹管密封设计，从而完全消除了阀杆填料密封泄漏的问题.满足严格的泄漏等级要求。如波纹管不幸失效，阀杆上填料密封可提供二次密封防止泄漏。
2.免维修-波纹管密封结构不仅杜绝了泄漏现象，而且无需维护，如需更换内部件，方便、简单、快速、所有部件达到标准、互换。
3.加脂注油-在阀帽/阀盖带有加脂庄油孔，可对阀杆和螺母轴套进行润滑。
4.球型锥面阀蕊-蒸汽截止阀采用独特球型锥面阀蕊代替传统的平面阀蕊，可手动粗略进行流水控制，阀蕊表面硬化处理，提高了密封性能
1. life - long steam cut-off valves are designed with a unique double bellows seal, which completely eliminates the leakage of the stem packing seal to meet the strictest leakage level requirements. If the bellows fail, the packing seal on the stem can provide two seals to prevent leakage.
2. free maintenance - bellows seal structure not only eliminates the leakage, but also needs no maintenance, such as the need to replace the internal components, convenient, simple, fast, all parts reach the standard, exchange.
3. grease injection. The bonnet / cap is lubricated with the grease filling oil hole, which can lubricate the stem and nut bushing.
The 4. ball type cone valve core - steam cut-off valve uses the unique spherical cone valve to replace the traditional plane valve, which can be manually controlled by water manually and hardened on the surface of the valve, thus improving the sealing performance.
