Detailed Introduction

刀形浆闸阀说明 SLURRY KNIFE GATE VALVE SHAPE DESCRIPTION

PZ73、PZ43、Z73

Product overview

1、Slurry knife gate valve in accordance with the caliber of different-shaped dark bar and the next shot is made in two forms(dark bar DN200～900mm,dear shot DN50～900mm),full circle design of the DC channel residue does not exist,no jamming.Knife blade-like plate at the bottom of processed,on soft materials such as fiber,pulp,wood pulp has a cutting function,while the role of a good opening and dosing.Knife board installed in the top of the hard Teflon scraper device,to prevent dust,sand and other substances into the packing box scratch can significantly increase the life of blades.Valve plate material selection of stainless steel,grinding polished for best sealing effect

2、Valve,filing culvert for the precision casting,in which the whole body with flange-type casting,stainless steel,hard alloy material can be selected according to user needs 304,316,316 L WCB,2Cr13, enhanced PTFE seals with PTFE vinyl material,corrosion,wear,do not stick residue.

3、Valve plate has five support points so a very good disc from the middle.When the valve is at the off-position,when and withstands the back pressure,the valve board does not have the displacement

4、Slurry knife gate valve can be configured to hand-shaped wheel,manual zipper,spur gear drive,bevel gear;pneumatic and electric

5、Knife gate slurry form can be made within the V-shaped,triangular,pentagonal channels to meet the requirements of fluid regulation and control.

6、Knife-shaped connection in the form of slurry valve wafer type,flange supporting ear,sealed with metal on metal seal,metal on polyurethane,with enhanced PTFE;soft seal.

Applicable medium

Gold powder,tailings,pulp,wood pulp,fibers,dust,chemicals,sewage treatment,settling ponds,ore,slag,slime, asphalt,bunker exit,fruits,grains,cement,slaughter house wastewater,air transport pipeline or beer brewed in the media.

Product characteristic

Compact design,small footprint,light weight,inexpensive,easy to install,aiming to halt the measures to improve the wear resistance,easy maintenance,easy to use and long life,and can be arbitrarily selected drive.
