Q: Why can't the pressure measuring point be set at the two ends of the gate valve when measuring the resistance loss of the gate valve?
the valve before the pressure measuring point, distance of valve straight pipe length is 5 times the diameter of the valve after the pressure valve, the distance is 10 times the diameter of straight pipe length.
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?
Explanation:Valve wells also called valve wells, underground pipelines and underground pipelines (such as tap water, oil, natural gas pipeline valve etc.) in order to facilitate the opening and closing part of network operation or overhaul when needed, a pit is a similar small room (or well), the valve installation in the pit where, for regular inspection, cleaning and dredging pipeline, to prevent the blockage of the pipeline project. The pit is called a well. There are valves, wells must have valves, but there is not necessarily a valve valve wells.
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: What do you mean by forged steel gate valves 800LB DN20 SW?
Is the forged steel gate 800LB is DN20 on SW welding pressure
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: The valve safety valve check valve + + + = exposed part of a water pump adapter? Five
Generally do not require safety valve, just install exhaust valve in individual places.
Q: What's the meaning of the gate valve model z41x 16Q?
Gate valve (Z) flange connection (4) wedge type single gate (1) rubber soft seal (X) -16 pressure) (Q)
Q: Notes on flat gate valves
Use, maintenance, maintenance and precautions1. valve before leaving the factory have made strength and sealing test, the use of all connections should maintain the initial state.2. this series of valve operating handwheel is marked with open and close rotary direction, and the upper part of rod is equipped with open and close height gauge for regulating indication.3. when the valve and pipeline welding, the valve should be opened, appropriate to protect the neck with moisture, minimize heat conduction, to prevent damage to the sealing packing parts.4. when the valve is closed, the lever shall not be used. When the gate is closed to the top, the handwheel shall be turned 1/2 so that the gate is in a floating state.5. in the use of the valve should be regularly to the valve cap injection grease joint into the quantitative grease.6., the valve in use, such as vulnerable parts and leakage, should be replaced in time.7., the valve in the overhaul process, the cavity should be cleaned, the assembly should be added to the transmission parts of grease.8. valve storage during the shutdown, the gate should be in the closed position, long-term storage should be placed in ventilated dry place, regular inspection and maintenance.
Q: What are the standards for the execution of cast iron dark pole gate valves?
Standard Specification for cast iron blind rod gate valves:1, design and manufacture: according to the provisions of GB/T12234-892, structural length: according to the provisions of GB/T12221-893, flange size: according to the provisions of JB79 GB/T9112-91314, inspection and test: according to the provisions of JB/T9092-99 GB/T13927-92Drive mode: manual, electric, gear drive;
