Q:What are the features and uses of the gate valve?: What is gate valve? What is the purpose of forged steel gate valves? What are the features of forged steel 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 gate valve movement direction perpendicular to the direction of the fluid, valve can only be fully open and fully closed, can not be adjusted and the throttle. The gate has two sealing surfaces, and the two sealing surfaces of the most commonly used gate valves form wedge and wedge angles vary with valve parameters. Gate valve drive classification: manual gate valve, pneumatic gate valve, electric gate valve.DefinitionGate valve means the closing of the valve (gate) along the central line of the vertical direction of the 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.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 betterValve also has shortcomings:The overall size and opening height are larger. Larger space required for installation.In the process of opening and closing, there is relative friction between the sealing surfaces, which may cause galling.Gate valve generally has two sealing surface, processing, grinding and maintenance to increase some difficulties.

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 is the difference between gate valves Z41W-16R and Z41W-16P?: According to JB/T308P stands for Cr-Ni stainless steelR stands for Cr-Ni-Mo stainless steelCr-Ni stainless acid resistant steel has CF8, CF3, F304, F304L, which applies to the medium of work, such as nitric acid oxidation acid.Cr-Ni-Mo stainless acid resistant steel has CF8M, CF3M, F316 and F316L, which is suitable for working medium, such as acetic acid and reducing acid.

Q:Why does the fire hydrant box in the air defense area need to be added with gate valves?: when the envelope from the introduction of civil air defense, air defense should be set in the side of retaining structure; through the protection unit between the closed wall, should be installed in the pipe walls on both sides of the door closed;2 protection valve nominal pressure shall not be less than 1.OMPa;

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: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:Does the relief valve have a gate valve?: No The front end must be in control.

Q:Analysis of the advantages of elastic seat sealing gate valve?: General valve on the market for a long time there is Water Leakage or rusting, overcome the valve seal bad, rust and other defects, using the elastic elastic valve seat seal gate produce small quantities of elastic deformation of the compensation function to achieve a good sealing effect, with a switch to lighter and reliable sealing, good elastic memory and life and other significant advantages. The utility model can be widely used as an adjusting and intercepting device for pipelines such as water supply, sewage, building, petroleum, chemical industry, food, medicine, light industry, electric power, ship, metallurgy, energy system, etc.. This is the advantage and advantage of an elastic seat seal gate valve.

Q:What is the difference between Z41X gate valve and Z45X gate valve?: All flange soft sealing gate valve, but 41X is Ming bar, 45X is dark pole

Q:What is the size and length of the DN80 gate valve? 10 kg and 16 kg, respectively?: Valve structure length standards are PN16, short series for 203mm, long series for 280mm, flange size by PN16.
