  LZ系列螺旋閘(zha)門用于建材(cai)、冶金、礦山、電(dian)力、化工、玻璃(lí)、輕工、糧🐪食等(děng)🧑🏽‍🤝‍🧑🏻行業的庫頂(ding)、庫底及進出(chū)口等。是控制(zhi)🙇🏻流量變化較(jiào)大，啟動頻繁(fan)，切斷迅速的(de)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(jie)構特點：

Structure characteristic:

  結構(gou)簡單、操作靈(líng)活、重量輕、無(wú)卡阻、切斷快(kuài)，特别适用于(yú)🈲各類♈無粘度(dù)的固體、粉料(liao)及小于Φ10mm的顆(kē)粒料，晶🌍粒料(liao)的輸送及流(liu)量調節，安裝(zhuang)不受角度限(xian)制， 操作方便(bian)， 能随時調節(jie)開度。該閥門(mén)有手輪和鍊(liàn)輪操縱兩種(zhong)操作形式，I型(xing)為手輪，II為鍊(lian)😄輪。單向和雙(shuang)向兩種💔結構(gou)形式，LZD為單向(xiang)、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(zuò)原理：

Working principle

  主要由(yóu)框架、閘闆、絲(si)杆、螺母等零(ling)件構成，用手(shǒu)轉動手🐆輪🔴使(shi)絲🌈杆帶着絲(si)杆螺母和閘(zha)闆沿水平方(fāng)向往複運動(dong)，達到閘❤️門的(de)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(an)裝或垂直安(ān)裝，安裝時兩(liang)法蘭連接中(zhōng)間必須加密(mì)封墊片，然後(hou)鎖緊螺栓。

l  操(cao)作時手輪順(shùn)時針旋轉為(wéi)閥關，反之為(wéi)開，不得在手(shǒu)💰輪上再♉增加(jia)輔助杠杆。

l  若(ruo)長期存放應(yīng)使設備處于(yú)關閉狀态，各(gè)傳動部位🔱應(ying)加潤👄滑油，不(bu)允許露天存(cun)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.
