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:How big valves and fittings need flange installation, such as gate valves, DN50, DN80 and the like?.
Flanges for piping above DN50,DN50 (below) can be made of wire or flange (flange for pressure piping)
Q:The difference between flanged gate valve and common gate valve
Flange valve: English name; Flange Gate 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. Gate has two sealing surface, the most commonly used mode gate valve of the two sealing surface to form a wedge, wedge angle with valve parameters vary, usually 50, medium temperature is not high when 2 degrees 52'. Wedge 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 of deviation, make up the sealing surface angle in the process, the gate is called the flexible gate.Ordinary gate valve: mainly used to connect or cut off the medium in the pipeline, not applicable to regulating medium flow. Gate valve applies to pressure, temperature and caliber range is great, especially for medium, large diameter pipesThe most important difference: flange gate valve and ordinary gate valve is different, flange gate valve quality, durable, easy to install, but higher prices, generally used for large pipelines. Ordinary gate valves are used for small caliber, easy to change places.
Q:Stainless steel gate valve DN150 200300 weight, who knows?
It depends on different materials and pressure levels. 304 material, high pressure weight will be much heavier.
Q:The difference between gate valve and butterfly valve, as well as cut-off valve,
The gate valve is one of the simplest valves. Generally manual, most of the electric valve failure, as a manual. Butterfly valve is more, I saw the pneumatic butterfly valve, that is, with gas control closed, general and solenoid valve matching.Without strict conditions and advantages and disadvantages, of course, the equipment requires a relatively high degree of automatic control. I can check it out on Baidu.
Q:What are the advantages and disadvantages of flat gate valves?
The advantage of flat gate valve is that the flow resistance is small, and the flow resistance is similar to the flow resistance of short valve. The flat gate valve with guide hole is installed on the pipeline and can be directly cleaned with the cleaner. As the gate is sliding on the two seat surface, the flat gate valve can be applied to the medium with suspended particles, and the sealing surface of the flat gate valve is actually positioned automatically. The seat seal surface is not subject to thermal deformation of the valve body. Moreover, even if the valve is closed in cold condition, the thermal elongation of the stem will not cause the seal to be subjected to overload. The length of the structure is much shorter than that of the ball valve, and it is easier to start. Light plate gate valve is more refined, but the effect is exactly the same.
Q:What is the difference between the copper gate valve and the ordinary material gate valve?!
The copper gate valve is made of copper alloy, and the common materials are made of stainless steel, cast steel, cast iron, and so on. Now there are new types of ceramic gate valves. Different properties of the gate valve performance, processing technology, service life, applicable occasions are a certain difference. Copper gate valves should be used for fire end water outlet installations as well as other occasions with special requirements.
Q:What is the standard length of GB steel gate valve?
1, product standardsGeneral purpose valves, flanged connections, iron gate valves, GB/T 12232-2005General requirements for steel valves GB/T 12224-2005"Steel flat gate valves for pipelines" JB/T 5298-91Inspection and test of valves. JB/T 9092-1999Standard for safety evaluation of drinking water distribution equipment and protective materials GB/T 17219-1998
Q:What does gate valve Z41H-40 mean?
Z-- valve, 4-- connection, flange connection, 1-- structure, open bar wedge type rigid single gate valve, surfacing iron hard alloy h-- seal, 40- nominal pressure is 40 kg, which is 4.0MPa, the material is carbon steel casting
