  LZ系列螺旋閘門(mén)用于建材、冶金(jīn)、礦山、電力、化工(gong)、玻璃、輕工、糧食(shi)等行業的庫頂(dǐng)、庫底及進出口(kǒu)等。是控制流量(liang)變化較大，啟動(dong)頻繁👨‍❤️‍👨，切斷迅速(su)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(jié)構特點：

Structure characteristic:

  結構簡(jiǎn)單、操作靈活、重(zhòng)量輕、無卡阻、切(qie)斷快，特别适🐉用(yòng)于😘各類無粘度(du)的固體、粉料及(ji)小于Φ10mm的顆粒料(liao)，晶粒料的輸送(song)及流量調節，安(ān)裝不受角度限(xiàn)制， 操作方便， 能(neng)随時調🔞節開度(du)。該閥門💋有手輪(lún)和鍊輪操縱兩(liǎng)種操作形式，I型(xíng)為手輪，II為鍊輪(lun)。單向和💰雙向兩(liǎng)種結構形式，LZD為(wei)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(gong)作原理：

Working principle

  主要由(yóu)框架、閘闆、絲杆(gan)、螺母等零件構(gòu)成，用手轉動手(shǒu)🚶‍♀️輪使絲杆帶着(zhe)絲杆螺母和閘(zhá)闆沿水平方向(xiàng)往複運動，達到(dào)閘門的💋啟閉目(mù)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(fa)可水平安裝或(huò)垂直安裝，安裝(zhuāng)時兩法蘭連接(jie)中🏃間必須加☀️密(mi)封墊片，然後鎖(suǒ)緊螺栓。

l  操作時(shi)手輪順時針旋(xuan)轉為閥關，反之(zhi)為開，不得在手(shou)輪上再增加輔(fǔ)助杠杆。

l  若長期(qi)存放應使設備(bèi)處于關閉狀态(tài)，各傳動部位♉應(ying)加潤滑♋油，不允(yun)許露天存放或(huò)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.
