Q:What is plug welding gate valve?
Plug connection pipeline welding mode safety gate valve
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: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: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:Notes on flat gate valves
internal structureThe 1 seat O ring seal and preload floating seat structure, so that import and export of two-way valve seal plate; and the structure of the normal valve opening and closing torque only 1/2, can easily open and close valves2. when fully open, the channel is smooth and straight, the flow resistance coefficient is extremely small, and there is no pressure loss. The pipeline can be cleaned through the hair bulb3 the packing structure with the ability of self sealing, without frequent adjustment, opening and closing very lightweight, and reliable seal, the stuffing box is arranged at the auxiliary seal oil into the structure, absolutely reliable sealing performance, thereby achieving zero leakage; solve the shortcomings of the general valve packing leakage of the most vulnerable4., when the flat gate valve is closed, it can automatically unload the inner cavity high pressure, and ensure the safe use5., fully enclosed structure, good protection performance, can adapt to all-weather requirements6., the valve seat sealing structure should be elastic, preload, upper and lower sealing seat at the same time sealed structure. The valve seat and the seal are always face to face sealed.The 7. seat has self-cleaning function and is free of direct airflow during valve opening or closing. The seat shall be made of lubricated, non wearing material.8. valve actuator failure will not affect the other parts of the valve, maintenance and replacement work can be carried out without removing the valve.9. yoke sleeve aluminum bronze yoke sleeve with pin type thrust bearing to minimize operation torque.10. stem - thread length until bracket; dowel and spot welding; stability.11. pressure seal - simple construction, with sectional retaining rings and silver plated low carbon steel gaskets, helps to remove and achieve the best bonnet seal.12. seat ring - welded seat ring is perpendicular to the flow channel and is easy to maintain.
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: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 does gate valve DN200PN160 mean?
Please tell the specific specifications and specifications of the gate valve and advise the principle of management cooperation Thank you
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:What do you mean by forged steel gate valves 800LB DN20 SW?
Is the forged steel gate 800LB is DN20 on SW welding pressure
