Q:What are the specifications of the gate valves? Does the work pressure need to be marked separately?
Gate valve code Z, such as GB gate valve Z41H-16. Front is the valve type, and the back 16 represents the pressure of 16 kg, 1.6MPa
Q:Why is gate valve or butterfly valve used for water pump?
General pressure is small, use the butterfly valve, when the pressure is big, use the gate valve. The two main function of the valve is to adjust the flow and easy to overhaul.Zibo Boshan new Duke water supply equipment
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:What are the differences between the gate valve and the cut-off valve?
3, 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 a variety of occasions, such as the valve rod the dark bar valve, gate valve, wedge gate valve, single valve, multi valve valve body structure is different, large volume. Generally large and nominal caliber DN50 mostly with gate valve, especially industrial high temperature, high pressure and other occasions.4, the cut-off valve is able to stop and adjust the flow, small footprint, small size, generally less than the nominal diameter, DN50 occasions use it. Two can be closed, in the flow of linear requirements are not high, you can adjust the flow. Just because of its structural characteristics of the valve to make its flow resistance, so there is a demand for throttling with a little more than the gate valve. In addition, the cut-off valve, whether it is a formal or reverse installed, in the opening and closing process, there is always a very difficult, and therefore can not do a great deal, or it is not easy to open and close. In addition, the sealing valve has the characteristics of one-way sealing effect, so that the utility model can prevent the working substance from flowing upstream
Q:What is the Z15T-16C letter of the gate valve?
The Z class code indicates the type of gate valve, gate valve is the first letter of the alphabet. The gate is manual driving mode, 1 said the connection form of gate valve for connecting thread, 5 represents the structure form of gate valve for rigid single gate, T gate said lining material of copper alloy, 16 PN1.6MPa nominal pressure valve. C said the valve body material is carbon steel.
Q:Acid resistant alkali valve gate valve
D is small in shape and beautiful in appearance.E operation is simple and labor-saving.
Q:TitleThe difference between gate valve, butterfly valve and stop valve
The gate (gate valve) is a gate 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 gate valve. The 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.Gate valve advantages: 1, fluid resistance is small,.2, opening and closing more labor-saving,.3, medium flow unrestricted, not disturbed flow, do not reduce pressure,.4, simple shape, structural length is short, manufacturing process is good, a wide range of applicationsValve shortcomings: 1, between the sealing surface is easy to cause erosion and abrasions, maintenance is more difficult,.2, big size, open need some space, opening and closing time is long,.3, the structure is more complex
Q:Function of signal butterfly valve and gate valve
The signal butterfly valve applies to petroleum, chemical, food, medicine, papermaking, water and electricity, ships, water supply and drainage, smelting, energy and other system pipelines. It can be used as regulating and throttling devices in a variety of corrosive, non corrosive gases, liquids, semi fluids, and solid powder pipelines and containers. It is widely used in high buildings, fire protection systems and other piping systems that need to display valve switching status.
Q:Gate valve z45h-10dn250 length of the body?
Z45h-10dn250 body length L=330mm, this valve is hidden bar, elastic seat, sealing gate valve, gate lining, lining fluorine, belong to soft seal
Q:What kind of copper gate valve copper content standards, there are no national standards?
Usually copper alloy, rarely used pure copper, there are GB
