Q:What are the common standards for gate valves?
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. The following common standards for Fujian Biaoguang valve for valve: design specification: JB/T 7746, API602 JB/T 7746, the length of the structure specification / thread socket factory test and inspection of JB/T1751/GB7306, ANSI: B16.11/B2.1: JB/T 9092, API598 pressure temperature: GB/T 9131, ANSI B16.34, MSS GB/T 12220 product ID: SP25 delivery specification: JB/T 7928
Q:What is a protective gate valve? What is gate valve knowledge?
Explosion-proof valve products, is a kind of safety valve can eliminate the shock wave which can stop the water hammer shock wave, it is a product composed of multiple sets of safety,
Q:What does the gate valve 150# mean?
150Lb (American Standard pressure value corresponding to the PN2.0)
Q:Why does the centrifugal pump start and stop in the case of closing the gate valve?
Centrifugal pump to close the gate valve in the case of the start: the centrifugal pump power increases with its flow rate, when the flow is zero (valve closed), the minimum power to operate. Start the valve off from the angle of the motor. If the valve is started, the motor itself to start the current is larger, coupled with the power of the pump is also large, easy to cause the motor over-current trip, serious will burn the motor.
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: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:The difference and use of gate valve and stop valve
Standard light valve professionals to answer for you, gate valve refers to the closure of parts (gate) along the central line of the vertical direction of moving valve. The gate valve is mainly used for cutting in the pipeline. The valve is a valve with a very wide, cutting device general caliber DN = 50mm use it, sometimes a small diameter cutting device also use valve, gate valve has the following advantages:Fluid resistance is small.Minor force needed for opening and closing.
Q:What does "Z45W-10T" mean?What does each letter stand for?
W is the seal material or lining material code, the valve sealing material is the valve body material, the valve sealing surface material code with "W" said, here stands for brass;The 10 is the pressure code, which stands for PN10, which is often called 1.0MPa;
Q:Which is more expensive, bronze gate valve or brass gate valve?
The advantage of casting method is more obvious. The casting of stainless steel is much more difficult than that of brass.
Q:What is an inverted seal gate valve?
When the inverted sealing gate valve is fully opened, the sealing of the sealing is brought together, and the sealing effect is reduced, and the erosion of the filling to the fluid is reduced, and the service life of the filler is prolonged, and the possibility of leakage is reduced. Generally on the gate valve, stop valve has inverted sealing requirements.
