Q:What are the specifications of the gate valves? Does the work pressure need to be marked separately?
5- dark pole single wedge gate valve, 6- dark bar wedge gate valve 7-, dark bar parallel gate valve, parallel gate valve 9- dark bar;5, sealing materials or lining materials were used R- T- austenitic stainless steel, copper alloy, X- rubber, S- plastic, N- nylon, F- fluorine plastic, H-Cr series stainless steel, hard alloy Y-, J- rubber, M- Monel alloy, Tc- ceramics;6, the body material code Z- K- gray cast iron, malleable cast iron, Q- ductile iron, copper and T- alloy, C- steel, P- chromium nickel stainless steel, R- stainless steel chromium nickel molybdenum, chromium molybdenum vanadium steel V-.For example: electric, flanged, rod wedge gate valve, sealing surface material by direct processing, nominal pressure PN0.1MPa of the valve body is made of grey cast iron gate valve: Z942W-1 electric wedge gate valve.
Q:What does "Z45W-10T" mean?What does each letter stand for?
T is the material code for the valve body, which stands for copper and copper alloysZ45W-10T, which means manual, flange connections, dark wedge rigid single gate plate, the valve seat sealing surface material directly processed by the valve body, nominal pressure PN10, valve body material for Brass Gate Valve
Q:What is gate well?
Gate valve well: it is a irrigation network system which aims at improving water utilization and efficiency, aiming at the construction of water saving and high-efficiency agriculture as well as scientific and technological innovation as well as convenient operation and management.
Q:What are the types and product categories of knife gate valves?
Types and classification of knife gate valves:PZ73H, PZ73F, PZ73Y manual knife gate valve: manual drive, clamp connections, rod parallel rigid single gate and valve seat sealing surface is made of hard alloy, Teflon or stainless steel body processing, nominal pressure.2PN10~16, the valve body material for carbon steel (PZ73H-10C/16C), stainless steel (PZ73F-10P/16P PZ73Y-10P/16P), with the function of slag gate valve.
Q:Does the tap belong to a stop valve or a gate valve?
Most taps are stop valves:1, gate valve (gate valve) is a headstock ram, RAM direction of motion perpendicular to the direction of the fluid, valve can only be fully open and fully closed doors, discomfort pumpsparameters vary, usually 5 degrees is not high, medium temperature is 2 degrees 52'. To improve its manufacturability, make up for the deviation of the angle of the sealing surface during processing. This gate is called an elastic ram.2, valve (stop, Globe, Valve) of the opening and closing parts are plug shaped valve, sealing surface is flat or sea cone, the valve along the center line of the valve seat in a straight line movement. Stem form of exercise (generic name: dark bar), but also lift rotating rod can be used to control air, water, steam, all kinds of corrosive media, mud, oil, metals and radioactive liquid media and other types of fluid flow. Therefore, this type of shut-off valve is very suitable for cutting or regulating and throttling. Because of the valve stem to open or close the trip is relatively short, but very reliable cut off function, and because changes in the valve seat and the valve stroke is proportional, is very suitable for flow regulation.The stop valve is an ascending stem type, and the handwheel rotates and rises along with the stem. Valve is hand wheel rotation, stem upward movement. Flow is not the same, the gate valve requires full open, the cut-off valve is not the same. The gate valve has no inlet and outlet direction requirements, and the cut-off valve has the required inlet and outlet!
Q:What is gate valve (with force transfer joint)?
Flange valve is equipped with a force expansion joints, easy installation
Q:What gate valve is the J41H-150LBDN100 gate valve?
J41H-150LBDN100 is not a gate valve, it is a API stop valve.API valve can only medium one-way flow direction when installing. Its structure length is larger than gate valve, and the fluid resistance is large. The reliability of sealing is not strong in long-term operation.Also called cut-off gate valve is the most widely used as a valve, it is popular is because the process of opening and closing the sealing surface friction between the small, more durable, highly open small, easy manufacture, convenient maintenance, not only for low pressure, but also suitable for high pressure.
Q:Installation and operation instructions of knife gate valve
1. knife gate valve installation, check the valve cavity and sealing surface and other parts, not allowed to dirt or sand adhesion;2. bolts of connecting parts must be tightened evenly;
Q:What is the meaning of socket welding gate valve A105, D&S:STLT, STEM:13Cr, CL800, SW, AP1602, BB-BG-OS&Y?
Body material: A105Sealing surface material: STLStem material: 13CrPressure rating: CL800Connection: SWImplementation criteria: AP1602BB-BG-OS&Y: plain rod support, bolt connection, flange valve cap.
Q:Pump adapter generally includes what accessories?
As everyone knows, the water pump adapter includes: gate valve, check valve, safety valve, the water outlet pipe and a combination of exposure. If it is a wall type, it should also include a decorative board. If the model is relatively simple and portable pump, pump adapter classification: SQS old ground fire pump adapter, SQD new type of pump adapter, SQB wall type water pump adapter. You can use Baidu Search: Shanghai Huanyao pump adapter
