Description：

A gate valve, an overview:
PZ973H series American Standard electric knife type valve , equipped with rotary electric device, the valve plate up and down motion, realize remote control valve to open or close the valve body made of cast steel, stainless steel, diameter range: DN50 ~ DN1000, the use of temperature is less than or equal to the nominal pressure: 425 C: 1.0 ~ 1.6MPa. Used in chemical, coal, sugar, water, paper and other fields, especially suitable for papermaking industry to make adjustment and throttle in the pipeline.
Two, structure principle:
1, PZ973H series American Standard electric knife type valve Is the gate opening and closing parts, RAM direction of motion perpendicular to the direction of the fluid, valve can only be fully open and fully closed, can not be adjusted and the throttle.
2, there are two gate sealing surface, the most common mode of gate valve sealing surface to form two wedge, the wedge angle varies with the valve parameters, usually 50, wedge knife gate valve can be made into a whole, called the rigid gate; can also be made to produce micro deformation of ram, in order to improve its process, make up the sealing surface angle deviations arising during processing, the gate is called the flexible gate.
3, knife gate valve is closed, the sealing surface can only rely on media pressure to seal, that media pressure will depend on the sealing surface of the ram pressure to the other side of the seat to ensure the sealing surface of the seal, which is self sealing. Most of the knife gate valve is sealed by force, that the valve is closed, to rely on external pressure to force the gate to the seat to ensure the sealing surface of the seal.
High temperature electric knife type valve driving part adopts multi turn electric device used to drive and control the opening and closing of the valve, the operator can control the valve in the indoor remote control, also can be the scene of manual operation, can also be matched with a computer to realize computer automatic control.
Three, product features:
1, American Standard electric knife type valve According to the different caliber made dark rod and rod forms (dark bar DN50 ~ 900mm, DN50 ~ 900mm rod), full circle design of the DC channel without slag, block. Processed into the bottom plate blade knife blade, on soft materials such as fiber, pulp, wood pulp with a cutting function, while the role of a good opening and closing. The upper blades installed in the hard Teflon wiper can prevent dust and scratch gravel and other substances into the packing box, can significantly increase the life of blades. The valve plate made of stainless steel and precision processing can obtain ideal sealing effect of grinding and polishing. Compact design, small occupying space, light weight, low price, easy to install, wear and anti blocking measures to perfect and convenient maintenance, convenient use and long service life, and can be arbitrarily selected drive.
2, valve body, filling culvert are precision casting, the whole body with flange type casting material, according to user needs with 304, 316, 316L, WCB, 2Crl3, PTFE seal with PTFE material, corrosion resistance, abrasion resistance, non stick slag.
3, the valve plate is provided with 5 supporting points, the valve plate has a good self alignment. When the valve is in the closed state, and under pressure, the valve plate does not shift.
4, slurry knife gate valves can be supplied with a handwheel, manual zipper, spur gear drive, bevel gear, pneumatic and electric.
5, slurry knife gate valve can be made within the V shape, triangle, Pentagon channel. V type gate control can be used as a regulator.
6, slurry knife gate valve connected in the form of clip, flange lug, metal to metal seal, metal sealing of soft polyurethane, with enhanced PTFE seal.
7, medium: gold powder, tailings, pulp, wood pulp, fiber, dust, chemicals, sewage treatment tank, ore, slag, coal, asphalt, outlet, fruit, grain, cement slurry, slaughter wastewater etc..
8, the working temperature:
Soft seal (PTFE):-40 to 180 DEG c;
Carbon steel: -29 to 425 DEG c;
Stainless steel: -40 to 600 DEG c;
CrMoV: C = 550;
Working pressure: 0.6 ~ 1.6MPa.
Four, American Standard electric knife type valve Technical specification:
