Detailed Product Description: | Bevel gear knife gate, PZ573 bevel gear knife gate valve, Shanghai brand - Valve Co., Ltd. Shanghai-quality and stability: the whole process of quality control, nuanced, comprehensive detection! Reasonable price: high internal cost control, reducing costs, to help customers! Fast delivery: advanced production lines, adequate stocking, shortening delivery time! Provide complete engineering solutions valve, bevel gear knife gate valve pre-sale, sale and professional services. Product Name: bevel gear knife gate valve Model: PZ573, PZ543 drive: bevel gear Connection: flange, clamp-type structure in the form of: Knife seal structure: hard seal, soft seal, seal-sided, double-sided seal pressure range : PN10 PN16 150LB Nominal Diameter: DN50- DN1200 common material: cast iron, WCB, stainless steel, duplex steel, etc. nameplate: male workers brand products described ordering process bevel gear knife gate valve flange on the folder with the overall installation, sealing V Ⅵ grade level, open and close the gate and seal without gaps, with a great cut and self-cleaning function, for use in heavy medium, and assisted with the bevel gear, to open and close very light effect, this valve is mainly used Modern industry on. Such as mining, paper, water treatment, oil and food. Bevel gear knife gate valve is introduced bevel gear knife gate valve A is straight trip off valves, knife gate valve plate head oblique edge of the media has a certain cut-off effect, suitable for medium-containing fibers and solids and sewage treatment systems, admirable manual, pneumatic, electric actuators, widely used in papermaking, mining, chemicals, sewage treatment and other process automation system. Bevel gear knife gate valve Features 1, the valve with the overall design ,, fluid resistance, flexible and easy to operate. 2, screw drive bevel gear knife gate valve dual plane bearing design, the transmission friction is greatly reduced, so that the valve is open, lightweight and smooth. 3, knife gate valve seat seal uses a movable seal, and the use of O-rings provide a preload preload against the valve seat seal leaked greatly reduced, for long-term use of seal pair of worn with automatic compensation increase life. 4, the fixed guide claw, no groove design, easy to cause the accumulation or jammed media. 5, the seat may need the media and working conditions, select metal seal or soft seal: gate using chrome-plated or ion nitriding, the shutter more wear and longer life sealing surface; soft sealing optional PTFE seats or enhanced PTFE seats or EPDM, NBR, sealing, and corrosion-resistant. 6, a wide range of media adaptation: good sealing performance and economic practicability, the operation can be manual, pneumatic, electric, practical range is very wide. Bevel gear knife gate valve design standard flange standard GB / T 9113.1-2000 JB / T 79.1-1994 HG 20592-2009 ASME B 16.5 EN 10920-1: 2001 strength and sealing test standard JB / T 9092 -1999 hardness sealing rating MSS SP 81-2001 40ml / inch pressure - temperature ratings GB / T 12224 -2007 ASME B16.34 -2003 ISO 7005-1 standard length of the structure MSS SP 81-2001 GB / T 12221-2005 J16 is a gate valve opening and closing parts The direction of movement of the fluid direction perpendicular gate, gate can only be fully open and fully closed, can not be adjusted and the throttle. Ram has two sealing surface, the two most common mode of sealing surface to form a wedge gate valve, wedge angle with the valve parameters vary, usually 50, the medium temperature is not high for 2 ° 52 '. Wedge gate valve can be made into a whole, called the rigid gate; can also be made to produce small quantities of deformation gate in order to improve its process, to make up the sealing surface angle deviations arising during processing, this gate board called the flexible gate. When the valve is closed, the sealing surface can only rely on media pressure to seal, which rely on the sealing surface of the medium pressure to ram pressure to the other side of the seat to ensure the sealing surface, which is self-sealing. Most of the valve is sealed by force, that is, when the valve is closed, to rely on external pressure to force the gate valve to ensure the tightness of the sealing surface. Gate valve with the valve stem linear movement, called the lift rod valve also called clear shot valve. Often movements are trapezoidal threaded rod through the top of the valve guides and valve nut on the rotary motion into linear motion, which is the operating torque thrust into action. Open the valve, when the gate valve lift height equal to the diameter of the 1: 1 times, the fluid channel is completely smooth, but at run time, this position is not monitored. Actual use, is the apex of the stem as a sign that the fixed position, as its fully open position. Temperature appears to consider locking phenomenon, usually open to the vertex position, and then rewind 1 / 2-1 circle, as the position of the valve fully open. Therefore, the fully open position of the valve, according to the position of the gate is determined that the stroke. Some valve stem nut located at the gate, handwheel drive stem rotation, leaving the gate to upgrade, this valve is called the rotating rod valve or valve called the dark bar. Valve closure member Principle (ram) movement do fully open and fully closed off with a vertical path along the centerline. Valve selection Gate Valve is mainly used to cut off or turn on the line of medium, is generally not as a regulator or throttling. Category gate valve can be divided according to different classification methods: parallel gate valve, wedge gate valve, lift gate, rotary valve rod, fast opening and closing valve, necking valve, flat gate valve and so on. Valve fluid resistance characteristics, the applicable pressure, high temperature range, medium flow unrestricted, good sealing performance. Contact Shanghai-Valve Co., Ltd.
