Q:What's the difference between an electric two position control valve and an electric butterfly valve?
The electric butterfly valve belongs to a kind of electric valve and electric control valve. The main connection modes of electric butterfly valve are flange type and clip type. The main forms of electric butterfly valve are rubber seal and metal seal. The electric butterfly valve controls the switch of the butterfly valve through the power signal. The product can be used as the shut-off valve, control valve and check valve of the piping system.
Q:Check valve; flexible joint `; installation order of electric butterfly valve
Connect the Songjiang rubber joint from the pump outlet. Check the 1 valve
Q:Why use special flanges for butterfly valves?
Butterfly valve to use special flange, butterfly valve itself is because of the structure of the decision, the butterfly valve to clip type connection, this pair of clamps is a special flange.Also known as butterfly valve, control valve has a simple structure, can be used for low pressure pipeline valve switching control is closed parts (disc or disc) is a disk, around the valve axis to achieve the opening and closing a valve, the valve can be used to control the flow of air, water, steam steam, all kinds of corrosive medium, mud, oil, metals and radioactive liquid media and other types of fluid. On the pipeline, mainly from cutting and throttling. Butterfly valve headstock is a disc shaped disc, in the valve body around its own axis of rotation, so as to achieve the purpose of opening or closing or regulation.
Q:Where are the exhaust valves, mud valves and butterfly valves?
The exhaust valve is used for the heating of the independent heating system, central heating system, heating boiler, central air conditioning, floor heating and solar heating system.Mud valve, also known as cover valve, commonly used in urban water plants, sewage treatment plants sedimentation tank bottom discharge sludge.Butterfly valve used in furnace, coal gas, natural gas, liquefied petroleum gas, city gas, hot and cold air, chemical smelting and power generation environmental protection engineering system, conveying a variety of corrosive and non corrosive media pipeline, used to adjust and cut off the media flow.
Q:Butterfly valve model D344H and D343 difference
In fact, almost all refers to the sealed variable eccentric butterfly valve.1, D344H-10C DN4002, D343H-10C DN400Let's talk about the similarities between the 2 Butterfly models: D stands for butterfly valves, 3 represents turbine drivers, and the middle 4 represents flanged connections,10 represents the pressure of 10 kg, C represents the butterfly valve, the material is cast steel, and DN400 stands for the caliber of the valve;To say that where there are differences between the 2 models, there is a place where there are differences, second means 4 of the first models is the new type sealing valve structure is variable eccentric, second of the second models of the 3 represents the structure of the valve is three eccentric, and three eccentric seal variable eccentric type is in fact a meaning.Sealed three eccentric butterfly valve, sealed variable eccentric butterfly valve, corresponding to the central butterfly valve and sealed single eccentric butterfly valve.
Q:The difference between butterfly valve and gate valve
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.
Q:How do you explain A in butterfly valve D37A1?
Represents a seal or lining material symbol.Said sealing ring or lining material with the Chinese phonetic alphabet: B Babbitts D nitrided steel, acid resistant stainless steel H, J L Aluminum Alloy, hard rubber, nylon NL, P leather, SA PTFE, SC PVC, SD bakelite, T copper, TC enamel, X rubber, Y hard alloy
Q:Function of signal butterfly valve in fire sprinkler system
The signal butterfly valve is generally installed in two parts: floor level, dry pipe, flow indicator front end, trunk pipe, wet alarm valve, front end.Floor level pipe installation is a function of the signal valve, when the floor spraying system needs repair, close the valve, open the end of the floor drain, emptying the water in the spray system, maintenance; two is the sprinkler system is not allowed inside water, when the butterfly is closed, will transmit a signal to the the fire alarm system, fire alarm system receives a monitoring signal (so called signal butterfly valve), fire sprinkler system that the floor is anhydrous state, fast repair.Wet alarm valve at the front of the signal butterfly valve with the main floor of the main role of the butterfly valve, first, maintenance, and two is the prompt sprinkler system, there is a signal butterfly valve closed, should be repaired as soon as possible.
Q:Butterfly valve switch direction respectively?
If it is not to sound from behind, from large to small if that is in the open.
Q:What does the butterfly valve D361H - 25C DN350 mean?
Welded turbine butterfly valve, hard seal, material: cast steel, pressure 25KG, caliber 350MM
