Q: Gate valve, butterfly valve, ball valve advantages and disadvantages? What are the usual valves?: Commonly used valves are: gate valve, globe valve, check valve, ball valve, butterfly valve, safety valve, regulating valve, plug valve and so onValve: valve is closed parts (RAM) vertical movement of the valve in the pipeline along the channel axis, used primarily as a medium cut that open and close use. In general, the valve can not be used as a regulation flow. The utility model can be applied to low temperature pressure, and can also be applied to high temperature and high pressure, and can be made according to different materials of the valve. But the valve is generally not used to transport mud and other media pipeline.Advantages: fluid resistance is small; the opening and closing torque needed by the smaller; can use the ring pipe flow to the two direction in the medium, that is to say the unrestricted flow of medium; the fully open, the sealing surface by the erosion of the working medium is smaller than the cut-off valve; the body has the advantages of simple structure, manufacturing good craft; the structure of relatively short length.Disadvantages: the size and height on the larger required installation space is larger; in the process of opening and closing, a relative friction sealing, friction is large, even scratch phenomenon caused by easily at high temperature; the valve has two sealing surface, to processing, polishing and maintenance of some increase the opening and closing time difficult.

Q: Gate valve DN65 what does that mean?: DN65 indicates that the valve bore is 65CM.The gate (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.

Q: What else, P54140V, 170V? What do they mean?: P work pressureP54 temperature at 540 degrees of work pressureThe pressure at P54 100 is 540 at the temperature of 100barV valve for chromium molybdenum vanadium steelP54 pressure 140V temperature at 540 DEG C for 140bar valve for chromium molybdenum vanadium steelP54 pressure 170V temperature at 540 DEG C for 170bar valve for chromium molybdenum vanadium steelFrom the JB/T4018 "valve type model preparation method"The standard unit is MPa, but it is usually used in bar

Q: Stainless steel gate valve DN150 200300 weight, who knows?: The weight of DN150/200/300 is 134/192/379kg. Of course, different manufacturers may vary in weight, but not much.It's not that heavy at all

Q: Does the tap belong to a stop valve or a gate valve?: Most faucets are stop valves,Part of the faucet is plug valve,Hot water nozzles are almost all plug valves.

Q: Yes, soft sealing gate valve can reach 25 kilograms, Fujian light valve company has this type of soft sealing gate valveAnonymous browsing | 28 times: Soft seal butterfly valve seal is good, but can only withstand up to 16 pressure, or the plastic can not stand. A short period of time is OK, and it's also related to the workmanship and quality of the factory. The quality is poor.

Q: What do gates, Z15T-10, Z15W-16T, Z45T/W-10, Z41T-10 mean?: Z15T stands for manual, internal thread connection, dark wedge single gate. The sealing surface is made of copper alloy. The nominal pressure is PN1MPa;Z15W-16T for manual, internal thread connection, dark wedge type single gate, the valve body material is copper alloy, the valve seat sealing surface material directly processed by the valve body, nominal pressure is PN1.6MPa;Z45T/W-10 stands for manual, flange connection, dark wedge single gate. The valve body is made of copper alloy, and the valve seat face material is directly machined by the valve body. The nominal pressure is PN1MPa;Z41T-10 stands for manual, flange connections, plain wedge single gate, sealing surface material is copper alloy, nominal pressure is PN1MPa.According to domestic valve model standards, the valve model is by the valve type, gate valve drive mode, gate valve connection, gate valve structure, sealing material, valve body material code to indicate

Q: What's the meaning of flexible z45x-10q door valve?: Crown valve pressModel Z45X-10QZ refers to gate valve4 finger flange connection5 refers to the dark bar driveX refers to rubber seals10 refers to 10 kg pressureQ refers to the body material, ductile ironFull bore flange soft sealed gate valve

Q: What is the difference between the cut-off valve and the gate valve?: What is the difference between gate valve and stop valve?:Gate valve and globe valve structure is different, the valve structure for hand wheel, with the stem rotating together to do the opening and closing movement. Valve structure is rotating handwheel, stem do lifting movement. The flow is different, the gate valve requires full open or full closed state, the cut-off valve does not need. The valve has the flow direction requirements, and the gate valve has no inlet and outlet requirements!Sealing performance comparison:Valve length is shorter than the cut-off valve, higher than the cut-off valve, the valve should pay attention to the installation of high elevation. The gate valve can be tightly closed with the sealing surface by the pressure of the medium so as to achieve the effect of not leaking.

Q: What is plug welding gate valve?: Socket welding valve valve cover design in three forms. The first is forging steel bolt type valve cover, according to this design form design of the valve, the valve body and the valve cover bolt nut connection, spiral wound gasket 316 clamp flexible graphite manufacturing: seal. Customers have special requirements can be used when the metal ring connection. Second design form is the welded bonnet, according to this design form of the valve, the valve body and the valve cover with a threaded connection, welded seal. Customers have special requirements can be used when the third is connected through welding. Self sealing valve cover, according to this design form design of the valve, the valve body and valve cover with a threaded connection, pressure from the dense ring seal.The editing characteristics of 1 valve design and manufacture in accordance with API602 and ASME B16.34. tested according to API 598, marked by MSS-SP-25.2. full diameter or diameter shrinkage 3 rod bracket type 4 self centering sleeve type 5 pressure plate bolt connection, spiral wound gasket seal type valve cover nut connection, welded seal type valve cover and screw connect the internal pressure self tightening type valve cover 6 integral sealing seat 7 socket end with ASME B16.118. threaded end (NPT) with ANSI/ASME B1.20.19. valve can be transformed into the throttle type, needle type, ball type and type check
