  LZ系列螺旋閘門用(yong)于建材、冶金、礦山(shan)、電力、化工、玻璃、輕(qing)工、糧食等💋行業的(de)庫頂、庫底及進出(chu)口等。是控制流量(liang)♍變化較大，啟動頻(pín)繁，切斷迅速的理(li)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.

結構特點(dian)：

Structure characteristic:

  結構簡單、操作靈(ling)活、重量輕、無卡阻(zǔ)、切斷快，特别适用(yong)🔴于各類無粘度的(de)固體、粉料及小于(yu)Φ10mm的顆粒料，晶粒料(liào)的輸送及流量調(diao)節，安裝不受角度(du)限制， 操作方便， 能(néng)随時調節開度。該(gāi)閥門有手輪和鍊(lian)輪操縱兩種操作(zuo)🏒形式，I型為🏃🏻手輪，II為(wei)鍊輪。單向和雙向(xiàng)兩種結構形式，LZD為(wéi)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.

工作(zuo)原理：

Working principle

  主要由框架(jia)、閘闆、絲杆、螺母等(děng)零件構成，用手轉(zhuǎn)動手輪使絲杆帶(dài)着絲杆螺母和閘(zha)闆沿水平方向往(wǎng)複運動，達到閘門(mén)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.

使用說明：

Usage explanation:

l  本(ben)閥可水平安裝或(huo)垂直安裝，安裝時(shi)兩法蘭連接中間(jiān)必須加✔️密封墊片(pian)，然後鎖緊螺栓。

l  操(cāo)作時手輪順時針(zhen)旋轉為閥關，反之(zhi)為開，不得在手輪(lún)上再增加輔助杠(gàng)杆。

l  若長期存放應(ying)使設備處于關閉(bì)狀态，各傳動部位(wei)應加潤🔞滑🔞油，不允(yǔn)許露天存放或堆(duī)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.

l   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.
