Q:What is the difference between an elastic gate valve and a rigid gate?
General rigid gate used in the temperature is not too high, the pressure is not too large occasions, flexible gate used in high temperature, high pressure, or relatively high sealing requirements.Valve closed, the sealing surface can only rely on medium pressure to seal, that is to rely on medium pressure to the gate sealing surface pressure to the other side of the seat to ensure the sealing surface seal, which is self sealing. Most of the valve is forced seal, that is, when the valve closes, to rely on external force to force the gate to the seat, in order to ensure the sealing surface sealing.
Q:What do gates, Z15T-10, Z15W-16T, Z45T/W-10, Z41T-10 mean?
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
Q:Which is the most expensive, check valve and gate valve?

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:What kind of copper gate valve copper content standards, there are no national standards?
Copper gate valves are made of brass and bronze, and the national standard does not require copper content.
Q:What type of flange does it fit with the gate valve?
This depends on the type of gate valve, valve standards are marked with matching flange standards. Different types of flanges for different gate valves are also different.The flange of General GB gate valve is GB/T9113 series.
Q:Internal screw current limiting gate valve (Tan Gang) PN5.0 DN15/ Phi 1 Rc1/2 what does that mean?
We did thatInternal thread current limiting gate valve (Tan Gang)Body material: carbon steelPressure rating: PN5.0 = 300LB American StandardNominal = DN15 = 1/2"Phi 1 = in the middle of the gate drilling a Phi 1 hole, so that in closing there will be a certain flow, that is, the minimum flow, that is, the current limit.Rc1/2 is thread, which is the connection
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:The legend of gate valve and stop valve
Compared with the cut-off valve, the main advantage is that the flow resistance is small, the flow resistance coefficient of ordinary gate valve is about 0.08~0.12, while the ordinary cut-off valve resistance coefficient is about 3.5~4.5. Opening, closing force is small, the medium can flow in two directions. The disadvantage is that the structure is complex and the height is large. The sealing surface is easy to wear. The sealing surface of the valve must be forced to close the valve to achieve sealing, in the same caliber, work pressure and the same drive device, the drive valve torque is 2.5~3.5 times the gate valve. This point should be noticed when adjusting the torque control mechanism of the electric valve.The sealing surface of the stop valve contacts each other only when the valve is completely closed, and the relative sliding amount between the valve core and the sealing surface is very small, so that the wear of the sealing cover is very small. The sealing surface of the valve cover, mostly due to the spool and sealing surface before the debris, or because of the closed state is not tight, causing the medium of high-speed erosion caused by.
