Usage/Applications of Knife Gate Valve
This knife gate valve is a new generation gate valve characteristic of small construction, low weight, and high material utilization. It is an ideal product for such sectors including sewage disposal, coal slurry, syrup, sludge, air, slag-water mix, water supply, papermaking, mining, etc.
The knife gate valve adopts metal-to-metal hard sealing or metal-to-rubber soft sealing. In the processing of valve switching on/off, the gate plate and sealing face are provided with special design, featuring limited friction and high durability.
The sealing of the knife gate valve represents a breakthrough in traditional sealing form. Upper cap structure changes large area rectangular sealing face of the upper sealing to small area circular sealing, with much enhanced sealing performance. Based on circular sealing, the valve is further provided with latest floating sealing construction in the world. Thus the upper sealing shares the same useful life with pipeline, so the overall useful life of the valve increases.
After envelope is added to the top of hand wheel, all the moving parts of the gate valve will be enclosed. Therefore, the rotation of lead screws between gate plate and stem will not block because of short supply of lubricating oil. In particular, the valve is applicable for long-term service in severely dusty and dry environment.
- Q:Fire protection gate valve from the wall how many distance there is no regulation?
- 1 meters away from the wall, leaving the maintenance and replacement distance
- Q:HVAC design, why is less than DN50 of pipe gate valve and cut-off valve,
- Have not heard of this requirement, before the ball valve and butterfly valve quality is rarely used now are good, can be used, but not easy to control the flow valve butterfly valve can close more time-saving, fluid resistance of small. HVAC branch pipe, to flow control, so the choice of gate valve and cut-off valve is more reasonable, and now choose a ball valve is also a lot.
- Q:Is the check valve in or behind the gate valve?
- Pump outlet, check valve, gate valve.Gate valve plays a regulatory role, is the main pipe. Such a sequence can ensure that the water flow during power failure does not cause damage to the gate valve.
- Q:Does the relief valve have a gate valve?
- With the ball valve, needle valve, with the valve did not see, but there should be some.
- Q:What does gate valve Z41H-40 mean?
- 40 kg flanged cast steel gate valve；Flanged gate valve, 40 pressure
- Q:About fire valve is gate valve or butterfly valve problems?
- Disease is generally in accordance with the design requirements, regardless of the butterfly or tie hair to meet the requirements, are two-way valve.
- Q:Acid resistant alkali valve gate valve
- Fluorine gate valve; material: carbon steel, cast iron; design standards: JB, GB, ANSI, BS, API, ISO, DIN, NFZ, lining valve;
- Q:What does the gate valve SZ45X-1.0 stand for?
- Z- stands for gate valves, 4 for flange connections, 5 for wedge wedge single gate, X for rubber seals, and 1.0- for PN1.0MP
- Q:What does gate valve Z44T-10-200 code mean?
- The meaning of the model is standard, the landlord himself to check the JB/T308 standard, Baidu library some, and is free to download:JB/T 308-2004 valve type method of preparation clear EditionHttp://wenku.baidu.com/view/5f798850ad02de80d4d84036.htmlZ = gate valve4 = connection: flange4 = structure form: double gateT = sealing surface material: Copper10 = nominal pressure: 1.0MPa, followed by no letters indicate body material: Cast Iron200 = nominal path: DN200
- 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!
