  LZ系列螺旋閘門用于建材、冶金、礦山、電力、化工、玻(bō)璃、輕工、糧食等行(háng)業(yè)的庫頂、庫底及進出口等。是控制流量變(biàn)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.

結構特點：

Structure characteristic:

  結(jié)構簡單(dān)、操作靈活、重量輕、無卡阻、切斷快，特别适用于(yú)各類無粘度的固體、粉料及小于Φ10mm的顆粒料，晶(jīng)粒料的(de)輸送及流量調節，安裝不受角度限制， 操作方便， 能随時調節開度。該閥(fá)門有(yǒu)手輪和鍊輪(lún)操縱兩種操作(zuò)形式，I型為手輪，II為鍊輪。單向和雙向兩(liǎng)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.

工作原理：

Working principle

  主要由框架、閘闆、絲杆、螺母(mǔ)等零件構成(chéng)，用手(shǒu)轉動(dòng)手輪使絲(sī)杆帶着絲杆螺母和閘闆(pǎn)沿水平方向往複運動，達到閘門(mén)的啟閉(bì)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  本閥可水平安裝或垂(chuí)直安裝，安(ān)裝時兩法蘭連接中間必須加密封墊片，然後鎖緊螺栓。

l  操作時手輪順時針旋轉為閥關(guān)，反之為(wéi)開，不得在手輪(lún)上再增加輔助杠杆。

l  若長期存放應使設備處于關閉狀(zhuàng)态，各傳動部位應加潤滑油，不允許露天存放或堆置。

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.

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.
