Q:Is the check valve in or behind the gate valve?
Check valve in the valve in front. To prevent water from flowing back.
Q:What's the difference between the knife gate valve and the stop valve?
Minor force needed for opening and closing.Medium flow is unrestricted.When opening fully, the sealing surface is eroded by the working medium smaller than the cut-off valve.The shape is relatively simple and the casting process is better.The valve is used in the system is relatively large, to close the gate off system; and the valve is used in the system is relatively small, and to adjust the flow quantity of the system, can not be closed gate and globe valves of different specifications for many kinds of occasions, the valve rod valve the dark bar gate valve, wedge gate valve, single valve, multi valve valve body structure is different, large volume.
Q:About fire valve is gate valve or butterfly valve problems?
Disease is generally in accordance with the design requirements, regardless of the butterfly or tie hair to meet the requirements, are two-way valve.
Q:What do you mean by gate valve type RVHX-0150-10 and Z45X-16Q?
Z45x-16q, Z means gate valve, 4 means flange connection, 5 refers to dark rod gate valve, X means rubber seal, 16 refers to nominal pressure 1.6MpaRVHX means manual gate valve, 150 refers to the caliber of DN150, and 10 indicates nominal pressure of 1.0MPa
Q:What are the specifications of the gate valves? Does the work pressure need to be marked separately?
5- dark pole single wedge gate valve, 6- dark bar wedge gate valve 7-, dark bar parallel gate valve, parallel gate valve 9- dark bar;5, sealing materials or lining materials were used R- T- austenitic stainless steel, copper alloy, X- rubber, S- plastic, N- nylon, F- fluorine plastic, H-Cr series stainless steel, hard alloy Y-, J- rubber, M- Monel alloy, Tc- ceramics;6, the body material code Z- K- gray cast iron, malleable cast iron, Q- ductile iron, copper and T- alloy, C- steel, P- chromium nickel stainless steel, R- stainless steel chromium nickel molybdenum, chromium molybdenum vanadium steel V-.For example: electric, flanged, rod wedge gate valve, sealing surface material by direct processing, nominal pressure PN0.1MPa of the valve body is made of grey cast iron gate valve: Z942W-1 electric wedge gate valve.
Q:Gate valve, butterfly valve, ball valve advantages and disadvantages? What are the usual valves?
Stop valve: a valve that closes the valve and moves along the center line of the valve seat. According to this form of valve movement, the valve seat opening change is proportional to the valve stroke. Because of the valve stem to open or close the trip is relatively short, but very reliable cut off function, and because changes in the valve seat and the valve stroke is proportional, is very suitable for flow regulation. Therefore, this type of valve is very cooperative for cutting or regulating and throttling.Advantages: in the process of opening and closing, because the friction between the valve and the sealing surface of the valve body is smaller than that of the gate valve, the utility model has the advantages of wear resistance. Second, the opening height is generally only 1/4 of the seat channel; therefore, it is much smaller than the gate valve; usually there is only one sealing surface on the valve body and the disc; therefore, the manufacturing process is better and the service is easy to maintain. Because its packing is generally a mixture of asbestos and graphite, it has a higher temperature resistance. Steam valves are normally used with stop valves.Disadvantages: as a result of the medium through the valve flow direction has changed, so the minimum flow resistance valve is higher than most other types of valves; second, due to longer travel, opening slower than the ball.
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: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 kind of gate valve is Z6CS-H102?
Z== valve type: gate valve6== pressure rating: 800LB, API602C== structure: bolt connection, valve cover, bolt connection gland, bright rod support typeS== connection form: socket welding, that is, SWH1== body material: A10502== inner material: seat sealing surface STL, gate sealing surface STL, valve stem 13Cr
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.
