LZ系列螺旋閘(zhá)門用于建材、冶金(jin)、礦山、電力、化工、玻(bō)璃、輕🈚工、糧食等行(háng)業的庫頂、庫底及(ji)進出口等。是控制(zhi)流量變化🙇🏻較大，啟(qi)動🌈頻繁，切斷迅速(sù)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.
結構(gou)特點：
Structure characteristic:
結構簡單、操(cāo)作靈活、重量輕、無(wu)卡阻、切斷快，特别(bie)适用❤️于各類♌無🈲粘(zhan)度的固體、粉料及(ji)小于Φ10mm的顆粒料，晶(jīng)粒料的輸送及流(liu)量📐調節，安裝不受(shòu)角度限制， 操作方(fang)便， 能随時調節開(kāi)度。該閥門有手輪(lún)和鍊輪操縱兩種(zhǒng)操作形式，I型為手(shou)輪，II為鍊輪。單向和(hé)雙向兩種結構形(xing)式，LZD為單向、LZS為雙向(xiàng)。
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.
Working principle
主要由(you)框架、閘闆、絲杆、螺(luó)母等零件構成，用(yong)手轉動🏃♀️手輪使♌絲(sī)✌️杆🔞帶着絲杆螺母(mu)和閘闆沿水平方(fang)向往複運動，達到(dào)閘☁️門的啟閉目的(de)。
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.

使用說(shuō)明：
Usage explanation:
l 操作時手輪順(shun)時針旋轉為閥關(guān)，反之為開，不得在(zai)🚶♀️手輪上再增加輔(fu)助杠杆。
l 若長期存(cun)放應使設備處于(yú)關閉狀态，各傳動(dong)部位👅應加潤滑油(you)，不允許露天存放(fang)或堆置。
l It can be installed in horizontal or vertical. Sealing gasket must be put on the connected, then equably tight the bolt.
l You can not add assistant lever to the hand wheel. Clockwise turn of hand wheel means the closing of valve, otherwise it means opening.
