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、閘板、絲桿、螺母等零件構(gòu)成，用手轉(zhuǎn)動(dòng)手輪使絲桿帶著絲桿螺母和閘板沿水平方向往復(fù)運(yùn)動(dòng)，達(dá)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. 主要零件材料及連接尺寸類別 A×A B×B C×C H L n-d 重量 單向 200×200 256×256 296×296 820 100 8-Φ12 62 250×250 306×306 346×346 930 100 8-Φ14 70.5 300×300 356×356 396×396 1050 100 8-Φ14 81 400×400 456×456 496×496 140 100 12-Φ14 114 450×450 510×510 556×556 1450 120 12-Φ18 130 500×500 560×560 606×606 1610 120 16-Φ18 147 雙向 600×600 660×660 706×706 1830 120 16-Φ18 169 700×700 770×770 820×820 2130 140 20-Φ18 236 800×800 870×870 920×920 2440 140 20-Φ18 303 900×900 974×974 1030×1030 2660 160 27-Φ23 424 1000×1000 10741074 1130×1130 2870 160 24-Φ23 636 說(shuō)明 LMD-單向 I-手輪 距地面小于1.7米用手輪，大于1.7米用鏈輪鏈條節(jié)數(shù)M=0.105X-113（X是絲桿中心離地面度度） 使用說(shuō)明： U sage explanation: ＆#8226; 本閥可水平安裝或垂直安裝 ， 安裝時(shí)兩法蘭連接中間必須加密封墊片 ， 然后鎖緊螺栓。 ＆#8226; 操作時(shí)手輪順時(shí)針旋轉(zhuǎn)為閥關(guān)，反之為開(kāi)，不得在手輪上再增加輔助杠桿。 ＆#8226; 若長(zhǎng)期存放應(yīng)使設(shè)備處于關(guān)閉狀態(tài)，各傳動(dòng)部位應(yīng)加潤(rùn)滑油，不允許露天存放或堆置。 ＆#8226; It can be installed in horizontal or vertical. Sealing gasket must be put on the connected, then equably tight the bolt. ＆#8226; You can not add assistant lever to the hand wheel. Clockwise turn of hand wheel means the closing of valve, otherwise it means opening. ＆#8226; 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.----------------------------------------------------------------------------------------------------------------------------------------------------------------相關(guān)刀型閘閥產(chǎn)品系列:螺旋閘門(mén)（插板閥） Z973X電動(dòng)漿液閘閥 手動(dòng)漿料閘閥PZ73H/Y手動(dòng)刀型閘閥 PZ43H/Y手動(dòng)單夾式刀型閘閥Z573X傘齒輪漿液閥 PZ573H/Y傘齒輪對(duì)夾式刀型閘閥Z673X氣動(dòng)漿液閥 Z73X鏈輪式漿液閥PZ43H/Y鏈輪單夾式刀型閘閥(梅花型)
