SLD 螺旋閘門,插板閥SCREW GATE VALVE
SLD 螺旋閘門,插板閥用于建材、冶金、礦山、電力、化工、玻璃、輕工、糧食等行業的庫頂、庫底及進出口等。是控制流量變
化較大，啟動頻繁，切斷迅速的理想設備。
This valve is widely used at the top and bottom of store house and carry port in metallurgical, mining, building material, food, chemical industries etc. It is the ideal equipment to control a great changing flow, to open and close frequently and to stop quickly.
SLD 螺旋閘門,插板閥結構特點Structure characteristic:
SLD 螺旋閘門,插板閥結構簡單、操作靈活、重量輕、無卡阻、切斷快，特別適用于各類無粘度的固體、粉料及小于 Φ 10mm 的顆粒
料，晶粒料的輸送及流量調節，安裝不受角度限制， 操作方便， 能隨時調節開度。該閥門有手輪和鏈**縱兩種
操作形式， I 型為手輪， II 為鏈輪。單向和雙向兩種結構形式， LZD 為單向、 LZS 為雙向。
This valve is simple in structure, handy to operate, light in weight, non-obstructive and quick to stop. It is suitable to be used to carry all kinds of solid material, particle and crystal particle whose diameter is below 10mm and to adjust the flow. It can be installed at any angle and operated handily. The size of its gate can be regulated at any time. This valve has two type of operation. One is manual wheel operation; the other is chain wheel operation. Ⅰ means manual wheel. Ⅱ means chain wheel. The valve has two type of construction LZD is signal direction and LZS is double direction.
SLD 螺旋閘門,插板閥工作原理Working principle
SLD 螺旋閘門,插板閥主要由框架、閘板、絲桿、螺母等零件構成，用手轉動手輪使絲桿帶著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。
It is mainly made up of frame, gate board, screw pole, nut etc. Rotate the handwheel by hand, then the screw pole drives the nut and gate board move in horizontal to and fro to open or close the valve.

SLD 螺旋閘門,插板閥使用說明U sage 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。
It can be installed in horizontal or vertical. Sealing gasket must be put on the connected, then equably tight the
bolt.
You can not add assistant lever to the hand wheel. Clockwise turn of hand wheel means the closing of valve,
otherwise it means opening.
The device should be in the shut-down if the valve-board is placed longer. Driving parts should add lubricated
oil. Placing in the open air and piling up is not permitted.
