RETZ瑞茨『进口氨用截止阀』详细介绍●RETZ截止阀系列●RETZ氨用截止阀●产品数据
?RETZ氨用截止阀精良加工，优化设计--
可选密封结构———硬密封，软密封
1、阀瓣和阀座进行研磨加工，提高使用寿命，保证内密封的可靠性。
2、在阀瓣处采用特殊工艺增加四氟系列的密封材料，适用于各种恶劣的腐蚀性工况，寿命长，密封性能可靠。
3、阀瓣和下阀杆采用的是铰链式连接，主要是为了密封面接触处的密封吻合度，使密封性能可靠，确保无泄漏。
4、流道优化，采用计算机模拟演示的结果进行制作，优化后比同规格阀门的流道能力增加10~50%，流阻系数低。
1. Disc and valve seat are lapping to improve the service life and ensure the reliability of inner seal.
2. Special process is adopted to increase the sealing material of tetrafluoroethylene series at valve disc. It is suitable for all kinds of harsh corrosive conditions, with long service life and reliable sealing performance.
3, the valve disc and the lower stem are hinge type connections, mainly for the sealing and sealing degree of the sealing surface, so that the sealing performance is reliable and no leakage is ensured.
4. The optimization of flow channel is made with the best result of computer simulation. After optimization, the flow path capacity of the same valve is increased by 10~50%, and the flow resistance coefficient is low.
?进口氨用截止阀特点
1.主密封波纹管组件,采用内藏式，免冲刷设计，免维修，降低运行成本，使用寿命长
2.辅助密封非金属填料,使用常带缓蚀剂的编织填料，更增加了可靠性，安全性以及耐高温，提供一个无需维护的条件
内限位装置,增加阀杆的上位，保护阀门的使用安全，有效的保护波纹管的弹性变量
3.阀杆、波纹管保护装置防转块,防止波纹管的横向扭转，确保波纹管使用寿命的性
4.填料压套,用于压紧填料，使密封性能更完好，增加填料的
1. the main seal bellows assembly adopts built-in type, no scour design, no maintenance, low running cost and long service life.
2. auxiliary sealing non-metallic fillers, using braiding packings with constant corrosion inhibitors, increased reliability, safety, and high temperature resistance, providing a condition without maintenance.
The inner limiting device increases the upper part of the stem, protects the safety of the valve, and effectively protects the elastic variable of the bellows.
3. stem, bellows protection device to prevent rotation, to prevent lateral torsion of bellows, to ensure maximum service life of bellows.
4. packing pressure sleeve, used to compress packing, make sealing performance better and increase packing.
