双向密封穿透式刀闸阀

进口双向密封穿透式刀闸阀性能描述 Performance description

双向密封穿透式刀闸阀的闸板与阀座始终紧密接触密封的阀门，其原理是闸板上开有一个通径大小的圆口，通过闸板启闭使得闸板上圆口跟通径做完全脱离和相吻合的动作，阀腔与闸板间隙较小，不会随着闸板移动而把介质停留在阀腔中。密封阀座为活动结构设计，有防腐和自动补偿功能 retz品牌  The gate and valve seat of the two-way sealing penetrating knife gate valve are always in close contact with the sealed valve. Its principle is that there is a round mouth with the size of the diameter on the gate. Through the opening and closing of the gate, the round mouth on the gate is completely separated and matched with the diameter. The gap between the valve chamber and the gate is small, and the medium will not stay in the valve chamber as the gate moves. The sealing valve seat is designed as a movable structure with anti-corrosion and automatic compensation functions

进口双向密封穿透式刀闸阀产品特性 Product characteristics

●阀杆保护罩套管：避免阀杆受到外部异物喷射 Valve rod protective cover sleeve: prevent the valve rod from being sprayed by external foreign matters

●位置指示器：显示刀闸阀位置（与限位开一同安装使用或仅安装位置指示器）Position indicator: display the position of knife gate valve (installed with limit switch or only installed with position indicator)

●两片式阀体：阀体内腔经过加工，内腔狭小不易积渣 retz品牌 The inner cavity of the valve body is processed, which is narrow and not easy to accumulate slag

●穿透式闸：板切割力强，表面平整 Penetrating gate: strong plate cutting force, flat surface

●加强型阀座：阀座具有补偿性，具可刮料并防止卡死 Reinforced valve seat: the valve seat is compensatory and can be scraped to prevent jamming
