Gate Valve Workshop

Q: what are their applicable conditions? Advantages and disadvantages?: Valve is closed parts (RAM) along the vertical axis of the mobile channel valve in the pipeline, used primarily as a medium cut that open and close, generally do not have to do with traffic regulation, it can be used for low temperature and low pressure can also apply to high temperature and high pressure, and according to the different valve material for different media. In various types of valves, gate valve is the most widely used.Advantages: low fluid resistanceSmall torque required for opening and closingYou can use the ring road in which the medium flows in the two direction, that is to say, the medium is free of flowWhen fully open, the sealing surface is less eroded by the working medium than the cut-off valveThe structure is simple and the manufacturing process is betterThe structure length is shortDisadvantages: the overall size and opening height are larger, the space required for installation is also largerIn the process of opening and closing, there is relative friction between the sealing surfaces, and wear more easily, and even cause friction at high temperatureGeneral gate valve has two sealing pairs, to the processing, grinding and maintenance increased the number of difficultiesLong opening and closing time;

Q: The difference between cut-off valve and gate valve: Structurally, the gate valve for the gate, down to the front and back seat seal; globe valve with spherical, taper and flat spool, down to the valve seat seal. Functional stop valves are generally used for pressure flow control. Gate valves are used for isolation.

Q: What is the difference between the model z81x-16q and z81x-16c of the groove gate valve?: Not 16qIs 16p, the former body is stainless steel, and the latter body is carbon steel

Q: What are the features and uses of the gate valve?: 1) advantages: sealing performance than the cut-off valve, the fluid resistance is small, open and close more effort, full sealing surface by the erosion of media, media flows from the restrictions, with double flow, small structure length, wide application range. 2) disadvantages: high size, open need a certain space, opening and closing time is long, in the opening and closing, the sealing surface is easy to erode and scratch, and the two sealing pairs bring difficulties to the processing and maintenance.3) use: gate valve is generally used in the caliber of DN15-1800mm pipes and equipment, and its dosage is great, mainly cutting off function, not allowed to throttle.

Q: What is the difference between cut-off valve and gate valve?: Simply put, the cut-off valve is one-way, only into, do not give up, the valve is two-way

Q: What is gate well?: Gate valve well: it is a irrigation network system which aims at improving water utilization and efficiency, aiming at the construction of water saving and high-efficiency agriculture as well as scientific and technological innovation as well as convenient operation and management.

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: Function of gate valve: 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's the difference between a soft seal gate valve and a hard sealed gate valve?: Soft sealing gate valve is rubber seal, F sealed, hard sealing gate valve is the medium of particles.

Q: Gate valve z41t what does that mean?: According to the provisions of the JB/T 308-2004 valve type programming method:Z = gate valve4 = connection form: flangeT = sealing surface material: copper alloy
