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: What else, P54140V, 170V? What do they mean?: P work pressureP54 temperature at 540 degrees of work pressureThe pressure at P54 100 is 540 at the temperature of 100barV valve for chromium molybdenum vanadium steelP54 pressure 140V temperature at 540 DEG C for 140bar valve for chromium molybdenum vanadium steelP54 pressure 170V temperature at 540 DEG C for 170bar valve for chromium molybdenum vanadium steelFrom the JB/T4018 "valve type model preparation method"The standard unit is MPa, but it is usually used in bar

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: 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?: Because of the unsteady flow of fluid near the inlet and outlet of the valve, the measured data cannot be obtained relatively accurately.

Q: How to distinguish between gate valve and cut-off valve?: Standard light valve professionals to answer for you, gate valve refers to the closure of parts (gate) along the central line of the vertical direction of moving 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.

Q: How big valves and fittings need flange installation, such as gate valves, DN50, DN80 and the like?.: See, you choose 100 of the pressure is not high, you can not flange

Q: Z41T one 10 gate valve and Z44T one, 10 gate valve difference: Z41T one, 10 is single gate, Z44T one, 10 is double gateAccording to the provisions of the JB/T 308-2004 valve type programming method:Z== gate valve4== connection: flange type1== structure: Rigid single gate4== structure: Rigid double gateT== sealing surface material: copper alloy10== pressure rating: 1.0MPa

Q: The valve safety valve check valve + + + = exposed part of a water pump adapter? Five: There is integration now.Pump adapter SQ100. All contain.

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: The legend of gate valve and stop valve: The working principle is different. The stop valve is an upward stem type, and the handwheel rotates and rises with the stem. Valve is hand wheel rotation, stem upward movement. Flow is not the same, the gate valve requires full open, the cut-off valve is not the same. The gate valve has no inlet and outlet direction requirements, and the cut-off valve has the required inlet and outlet!Gate valve and stop valve are shut-off valve, is the most common two valves.From the exterior, the gate valve is shorter than the cut-off valve, especially the bar valve needs a higher height space. Valve sealing surface has a certain degree of self sealing capacity, its spool depends on the media pressure tight contact with the valve seat sealing surface, to achieve tight leakage. Wedge gate valve spool angle is generally 3~6 degrees, when forced to shut down excessive or temperature changes of the valve core is easy to die. Therefore, high temperature and high pressure wedge gate valve, in the structure have taken certain measures to prevent spool stuck. The valve in the opening and closing valve and valve seat sealing surface contact and mutual friction is always so easy to wear sealing surface, especially in close off the valve, the valve before and after the great pressure, sealing surface wear is more serious.
