Gate is one of the most common open/close, use of ram (namely the open-close part, in the gate opening and closing a called ram or gate, gate called ram block) to connect (full open) or truncation (seated) line in the medium.It does not allow for river closure, use should be avoided in the open gate trace, because of the erosion of high-speed flow of medium will accelerate the damage of the sealing surface.Double DE gate at the channel center line perpendicular to the gate of the one-sided as lifting movement, like gate cutting medium pipeline, so as the gate valve.

Q:What is the difference between the cut-off valve and the gate valve?: When opening and closing, the valve core and valve seat sealing surface always contact and rub each other, so the sealing surface is easy to wear, the valve is close to shut down, the pressure difference between the pipe is very large, so that the sealing surface wear more serious.Gate valve and stop valve advantages and disadvantages:Valve is the advantages of small flow resistance, the media can flow in two directions, but there are tall, complex structure, sealing surface easy to wear shortcomings. The flow resistance of the gate valve is 3-5 times that of the gate valve. Open and close to shut down in order to seal the valve, the valve is completely closed when in contact with the sealing surface, the sealing surface wear is very small, because the flow of the main actuator with large valve should pay attention to adjust the torque control mechanism.

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 are the structural differences between parallel and wedge valves?: The structure of globe valve and gate valve. What does this article introduce first?What is parallel gate valve?The sealing cover is parallel to the vertical center line, so the sealing surfaces of the valve body and the gate are parallel to each other. This gate valve is the most common double gate plate, in order to shut down, so that the valve and gate two sealing surface contact closely asked, often used in two ram double sided thrust wedge block. Thus, when the valve is closed, the double side thrust block is contacted with the bottom of the valve body and is gradually stressed.

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: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:What is the allowable leakage rate of the gate valve D?: In GB/T 13927, the leakage rate of the valve is divided into 10 grades, namely: A, AA, B, C, CC, D, E, EE, F, G class. And stipulates that when the order contract does not specify, the metal sealing valve according to D requirements.

Q:Gate valve is gate valve, gate valve specifications, model code is generally what?: Valve lock plate valve, gate valve and code.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.1, gate valve type code named Z;2, gate valve drive mode code by letters, common 2- electric hydraulic, 9- electric, 6- pneumatic, 5- bevel gear drive, 3- turbo worm; manual do not need to write out;3, gate valve connection form code with letters to indicate, 1- internal thread, 2- external thread, 4- flange type, 6- welding, 7- pairs clamp type, 9- clamp, 0- card sleeve;4, the valve structure of code, 0- flexible wedge, 1- rod single wedge gate valve, 2- rising stem wedge gate valve, 3- parallel single gate valve, 4- parallel double gate valve, 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 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 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

Q:What does gate z41t-10 150 mean?: According to JB/T308-2004 "valve type programming method"Z gate valve4 flange connection1 Ming wedge single gateT sealing cover material is copper alloy10 nominal pressure PN10PN16 below no marked valve body code, body material is gray cast iron150 nominal size DN150
