| 結構特點 |
| 1、結 構設計采用針型閥，啟閉靈舌可靠，解決了原產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、中段可根據觀察位置，改變觀察角度，清晰直觀。 3、雙色水位計便于泛重巨離觀察，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. |
