螺旋閘門用于建材疼蛾、冶金、礦山艺配、電力察郁、化工、玻璃转唉、輕工皮钠、糧食等行業(yè)的庫頂稳捆、庫底及進出口等。是控制流量變化較大麦轰，啟動頻繁乔夯，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.

螺旋閘門（插板閥）結(jié)構特點：

Structure characteristic:

結(jié)構簡單潘吸、操作靈活醇疮、重量輕、無卡阻卤撬、切斷快巴移，特別適用于各類無粘度的固體、粉料及小于 Φ 10mm 的顆粒料柄楼，晶粒料的輸送及流量調(diào)節(jié)饮估，安裝不受角度限制， 操作方便殴据， 能隨時調(diào)節(jié)開度墙目。該閥門有手輪和鏈輪操縱兩種操作形式， I 型為手輪又信， II 為鏈輪胰绢。單向和雙向兩種結(jié)構形式， LZD 為單向抛冗、 LZS 為雙向切省。

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.

螺旋閘門（插板閥）工作原理 ：

Working principle

主要由框架、閘板帕胆、絲桿朝捆、螺母等零件構成，用手轉(zhuǎn)動手輪使絲桿帶著絲桿螺母和閘板沿水平方向往復運動懒豹，達到閘門的啟閉目的芙盘。

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.

螺旋閘門（插板閥）主要零件材料及連接尺寸

螺旋閘門（插板閥）使用說明：

U sage explanation:

＆#8226;  本閥可水平安裝或垂直安裝 脸秽， 安裝時兩法蘭連接中間必須加密封墊片 儒老， 然后鎖緊螺栓。

＆#8226;  操作時手輪順時針旋轉(zhuǎn)為閥關记餐，反之為開驮樊，不得在手輪上再增加輔助杠桿。

＆#8226;  若長期存放應使設備處于關閉狀態(tài)片酝，各傳動部位應加潤滑油囚衔，不允許露天存放或堆置。

＆#8226;  It can be installed in horizontal or vertical. Sealing gasket must be put on the connected, then equably tight the bolt.

＆#8226;  You can not add assistant lever to the hand wheel. Clockwise turn of hand wheel means the closing of valve, otherwise it means opening.

＆#8226;  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.
