RETZ工业/美国瑞茨,我们一直致力于流体控制领域的持续创新,始于2005……硬密封柱塞阀是一种用于控制流体介质的阀门,其核心部件是柱塞。它采用了硬质合金材料作为密封副,由精密磨削及抛光处理后的柱塞和在堆焊后的硬阀座面组成,经粗加工后分别进行渗碳、高频淬火及渗氮等热处理,硬度可高达58~64HRC,具有良好的耐磨性和耐腐蚀性,能够满足高温高压、强腐蚀等恶劣工况下的使用要求Hard sealed plunger valve is a valve used to control fluid medium, and its core component is the plunger. It uses hard alloy material as the sealing pair, consisting of a precision ground and polished plunger and a hard valve seat surface after surfacing welding. After rough machining, it undergoes heat treatment such as carburization, high-frequency quenching, and nitriding, with a hardness of up to 58-64HRC. It has good wear resistance and corrosion resistance, and can meet the requirements of harsh working conditions such as high temperature, high pressure, and strong corrosion

工作原理:
柱塞阀的关闭由一个不锈钢柱塞、上下两只富弹性密封圈及一个金属隔框组成,密封效果由柱塞与密封圈紧密配合来达到,柱塞插在两只密封圈中,密封面积远大于普通截止阀。当手轮旋转,通过阀杆带动柱塞在孔架中间上下往复运动来完成阀门的开启与关闭功能
