鍋爐壓力容器用水位計(jì)

結(jié)構(gòu)特點(diǎn) 1、結(jié) 構(gòu)設(shè)計(jì)采用針型閥，啟閉靈舌可靠，解決了原產(chǎn)品旋塞跑冒漏滴的老大難問題，排污閥門采用 球閥，操作方便。2、中段可根據(jù)觀察位置，改變觀察角度，清晰直觀。 3、雙色水位計(jì)便于泛重巨離觀察，可視距離白天20m,夜晚60m,汽紅水綠，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.  主要壓零件材料： Material for main parts 零件名稱 name of parts 閥材 valve materials 閥桿 seat ring 填料 packing 閥瓣、閥座 stem,sear ring 墊片 spacer 水槽壓板 water trough seasaw 平視鏡 horizontally views the mirror 三棱鏡 bevelled mirror 材料 material 鍛鋼 forged steel 2Cr13 柔性石墨 expanded graphite 2Cr13 柔性石墨 expanded graphite Q235 高溫光學(xué)坡璃 high temperature optical glass  性能 規(guī)范及主要連接尺寸：The technical data and Main size of appearance 型號(hào) type 試驗(yàn)壓力MPa Testing pressure 法蘭通徑 Flange Diameter 規(guī)格 Size 適用溫度℃ Applicalbe temperature 適用介質(zhì) Applicable medium 殼體 Shell test pressure 密封 Testing pressure B42H-25 B49H-25 3.75 2.75 25 安裝中心距觀察孔高 installment center distance boservation hole height 250 300 330 350 400 440 ≤350℃ 水、汽、油、氣等 steam、water、petroleum、etc B42H-40 B49H-40 6.0 4.4 145 165 190 220 ≤425℃ 注:另可供加長(zhǎng)系列化 工容器用液位計(jì)，長(zhǎng)度系列L=500、800、1000、1600等
