锅炉压力容器用水位计

结构特点 1、结 构设计采用针型阀，启闭灵舌可靠，解决了原产品旋塞跑冒漏滴的老大难问题，排污阀门采用 球阀，操作方便。2、中段可根据观察位置，改变观察角度，清晰直观。 3、双色水位计便于泛重巨离观察，可视距离白天20m,夜晚60m,汽红水绿，水、汽界面 清晰。 1.The structural design adopts the needle type valve. The open and dose is flexible and reliable, which has settled the difficulties of belching and leakage of faucet of former products. The drainage valve adopts ball valve operation. 2. To change the observation angle in middle section as per the observation position. 3. Double color water meter is convenient for long-distance obwrvatico. You can observe 20m from the meter in daytime,60m from meter at night. The vapor shows red color and water shows gawn color. The interface between water and vapor is very clear.  主要压零件材料： Material for main parts 零件名称 name of parts 阀材 valve materials 阀杆 seat ring 填料 packing 阀瓣、阀座 stem,sear ring 垫片 spacer 水槽压板 water trough seasaw 平视镜 horizontally views the mirror 三棱镜 bevelled mirror 材料 material 锻钢 forged steel 2Cr13 柔性石墨 expanded graphite 2Cr13 柔性石墨 expanded graphite Q235 高温光学坡璃 high temperature optical glass  性能 规范及主要连接尺寸：The technical data and Main size of appearance 型号 type 试验压力MPa Testing pressure 法兰通径 Flange Diameter 规格 Size 适用温度℃ Applicalbe temperature 适用介质 Applicable medium 壳体 Shell test pressure 密封 Testing pressure B42H-25 B49H-25 3.75 2.75 25 安装中心距观察孔高 installment center distance boservation hole height 250 300 330 350 400 440 ≤350℃ 水、汽、油、气等 steam、water、petroleum、etc B42H-40 B49H-40 6.0 4.4 145 165 190 220 ≤425℃ 注:另可供加长系列化 工容器用液位计，长度系列L=500、800、1000、1600等
