Q:The difference between gate valve and butterfly valve, as well as cut-off valve,
Butterfly valve is a disc type of open and close parts reciprocating reciprocating about 90 degrees to open, close and adjust the fluid channel of a valve.Advantages: the butterfly valve has the advantages of simple structure, small volume, light weight, material consumption, installation of small size, and torque is small, simple and rapid operation, and also has good flow characteristics of regulation and sealed off, is nearly 10 years the fastest growing valve, high temperature and high pressure, and to large diameter, high sealing function of the direction, long life, good adjusting features and a valve development.Disadvantages: the butterfly valve relative to the gate, ball valve pressure loss is relatively large, it is suitable for pressure loss requirements lax piping system.Under normal circumstances, it is not suitable for high temperature and high pressure pipeline system.Valve is closed parts (valve) moving along the centerline of the valve seat, 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 to, is also very suitable for the regulation of traffic.Advantages: in the process of opening and closing, the friction between the disc and the valve body is smaller than that of the gate valve, so it is wearableThe opening height is generally only 1/4 of the diameter of the seat channel, so it is much smaller than the gate valveGenerally, there is only one sealing surface on the body and disc, so the manufacturing process is good and easy to maintain;Disadvantages: the flow resistance coefficient is relatively large, resulting in pressure lossUnsuitable for large caliber productionThe opening and closing moment is larger and the structure length is longer.
Q:What gate DH10016, AM
The first Z represents the gate valve (the initial consonant of the Chinese phonetic alphabet for the gate); the second 2 represents the drive mode of the valve, that is, electro hydraulic drive.
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:Soft sealed gate valve and hard sealing gate valve which good?
If the caliber, material and pressure levels are the same, the current market price is still soft sealed gate valve, about 20-30%.
Q:Z41T one 10 gate valve and Z44T one, 10 gate valve difference
Z41T one, 10 is single gate, Z44T one, 10 is double gateAccording to the provisions of the JB/T 308-2004 valve type programming method:Z== gate valve4== connection: flange type1== structure: Rigid single gate4== structure: Rigid double gateT== sealing surface material: copper alloy10== pressure rating: 1.0MPa
Q:Gate valve z11h/y-16 what does that mean?
Product Name: internal thread gate valveItem number: Z11HProduct specification: DN15-50Product pressure: 1.6MPa-2.5MPaMaterial: cast iron, cast steel, stainless steelInternal thread gate valve nominal pressure 2.5Mpa, applicable temperature range -20-232-350, applicable medium: water, oil, gas and certain corrosive liquid (W.O.G), thread type G.NPT.BSPT.BSP.DIN259/2999.
Q:Is the gate valve clockwise or closed?
In general, the valve is clockwise turn off, in the case of special requirements under the opening.
Q:What is the difference between a flanged gate valve and a wire gate valve?
This is very simple, flanged gate valve is the valve with both ends of the flange, the installation of the pipe to weld the reverse flange, bolt with the pipe flange and valve flange connection. Valve is the valve ends with wire wire, a wire and wire points, and pipeline installation, connecting part with joint or head of the screw and the valve directly on the pipe screw connection.
Q:What does gate valve do?
Like other valves, the gate valve is used to block fluid flow. Is the gate valve 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.
Q:What kind of gate valve is Z6CS-H102?
Z== valve type: gate valve6== pressure rating: 800LB, API602C== structure: bolt connection, valve cover, bolt connection gland, bright rod support typeS== connection form: socket welding, that is, SWH1== body material: A10502== inner material: seat sealing surface STL, gate sealing surface STL, valve stem 13Cr
