Q:What are the common standards for gate valves?
1, product standardsGeneral purpose valves, flanged connections, iron gate valves, GB/T 12232-2005General requirements for steel valves GB/T 12224-2005"Steel flat gate valves for pipelines" JB/T 5298-91Inspection and test of valves. JB/T 9092-1999Standard for safety evaluation of drinking water distribution equipment and protective materials GB/T 17219-1998
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.
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:Which is the most expensive, check valve and gate valve?
In the case of DN50 Z15T-16 DN50: screw valve 46.200 thread copper bar gate valve Z15T-16 DN50 52 Z45F-16 DN50 97 flange valve flange valve rod Z44T-10 DN50 169 Z45T-116 DN50 flange valve dark bar 173 thread swing check valves DN50 52.090 thread straight type check valve DN50 57.280 flange screw check H44T DN50 129 flange valve lift check valve H41T-16 DN50 124
Q:What are the structural differences between parallel and wedge valves?
The advantages of dual gate plate is sealed and angle precision low temperature is not easy to make the wedge gate, the abrasion of the sealing surface and shim.The disadvantage is that the structure is complex, easy to stick in the dry medium, mainly the upper and lower baffles. After years of corrosion, the gate is easy to fall off. Although the single gate is sealed and angle accuracy requirements are relatively high, difficult processing and temperature change may make the gate wedge and other shortcomings, but has the advantages of simple structure, reliable use, especially to the flexible gate, can produce the micro elastic deformation to compensate for the deviation between the sealing surface angle processing, which is widely used at present.For more information about valves, please keep an eye on the valve knowledge section.
Q:Valve flange drawing n- up to what
A bolt hole used to indicate a flangeThe value of N indicates the number of bolt holesUp to the numerical representation of bolt hole size
Q:What valve is z45w gate valve?
Cast iron gate valve with turbine head, please contact me
Q:Function of signal butterfly valve and gate valve
The signal 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. Can be used to control air, water, steam, a variety of corrosive media, mud, oil, liquid metal and radioactive media and other types of fluid flow. Gate has two sealing surface, the most commonly used mode gate valve of the two sealing surface to form a wedge, wedge angle with valve parameters vary, usually 50, medium temperature is not high when 2 degrees 52'. Wedge gate valve can be made into a whole, called the rigid gate; can also be made to produce micro deformation of ram, in order to improve its process of deviation, make up the sealing surface angle in the process, the gate is called the flexible gate. Signal gate valve is usually horizontal installation.
Q:Yes, soft sealing gate valve can reach 25 kilograms, Fujian light valve company has this type of soft sealing gate valveAnonymous browsing | 28 times
Soft seal butterfly valve seal is good, but can only withstand up to 16 pressure, or the plastic can not stand. A short period of time is OK, and it's also related to the workmanship and quality of the factory. The quality is poor.
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
