手動密閉閘閥是我公司結合用戶反饋信息和多年生產實踐改進的新一代閘閥產品。廣泛應用于建材、冶金、礦山、電力，化工、玻璃、輕工、糧食等行業，是控制流量、調節或切斷粉塵物料的理想設備。
The valves are the newly improved products on the base of feedback of users and production practice of our company. It is widely used in the building material, metallurgy, mining, electric power chemical, glass, light industry and food industry etc. It is the ideal equipment to control flow, adjust or cut down powder material.

結構特點：
Structure characteristic:
密閉性強、操作靈活、傳動部分無污染、無粉塵影響、使用壽命長、無泄漏、安裝不受角度影響，能隨時開閉，調節物料流量，特別適用于無粘度的固體粉料及小于Φ10mm的顆粒料、晶體料、固狀料的輸送及流量調節。
This valve is good in seal, handy to open and closing, long life and not leaky. There is no contamination and dust influence in driving part. It can be installed at any angle. It also can be opened and closed at any time to change the flow of material. It is especially suitable for non-glutinosity solid powder and crystalloid, grain, solid material to be transported.

工作原理：
Working principle:
主要結構由框架、閘板、絲桿、螺母、密封副等零件構成。轉動手輪使絲桿帶動絲桿螺母和閘板沿水平方向往復運動，達到閘門的啟閉目的，同時密封副在閘板運動中阻攔粉塵不進入傳動腔內，無外漏污染。
The valve is mainly made up of frame, disc, pole, nut and seal etc. Rotate the handwheel driving the pole and nut reciprocate in horizontal. At the same time the seal can prevent dust from entering driving body and out-leakage pollution does not exist.


使用說明：
Usage explanation:
本閥可水平安裝或垂直安裝，安裝時兩法蘭連接中間必須加密封墊片，然后鎖緊螺栓。
操作時手輪順時針旋轉為閥關，反之為開，不得在手輪上再增加輔助杠桿。
若長期存放應使設備處于關閉狀態，各傳動部位應加潤滑油，不允許露天存放或堆置。
