Q:Import electric butterfly valve which brand is more reliable?
Recommend Sichuan Ding Heng petroleum machinery company sales agent SPM butterfly valve and FMC butterfly valve, we are partners for many years, have been working together are very happy.
Q:What kinds of butterfly valves are available? What is the working principle of butterfly valves?
According to the form of sealing:(1) forced sealing butterfly valve.1) elastic sealing butterfly valve. The pressure of the valve seat, seat, or plate is produced when the seal is closed by the pressure from the valve.2) additional torque seal butterfly valve. The seal is produced by a torque that is applied to the valve shaft.(2) pressure sealed butterfly valve. The pressure is greater than the pressure on the seat or plate.(3) automatic sealing butterfly valve. The pressure of the seal is automatically generated by the pressure of the medium.Divided by work pressure:(1) vacuum butterfly valve. Working pressure is lower than the standard atmospheric pressure butterfly valve.(2) low pressure butterfly valve. Butterfly valve with nominal pressure PN<1.6MPa.(3) medium pressure butterfly valve. Butterfly valve with nominal pressure PN 2.5--6.4MPa.(4) high pressure butterfly valve. Nominal pressure PN is 10. 0--80.0MPa butterfly valve.(5) ultra high pressure butterfly valve. Butterfly valve with nominal pressure PN>100MPa.
Q:Transformer butterfly valve and pressure relief valve difference
The oil immersed transformer pressure release valve is a safety device installed in the transformer, when the internal pressure is less than the limit value of the transformer such as 35kPa, which is in closed state, when the transformer internal fault occurs, a large number of transformer oil by pyrolysis, produce large amounts of gas, the internal pressure of the oil tank increased dramatically when the opening pressure exceeds the pressure release valve when the pressure relief valve opens, the internal oil and gas overflow, to release the pressure, avoid the pressure on the inside of the lead tank cracking or permanent deformation, when the fault of transformer internal end, internal pressure tank to reduce pressure release valve closing pressure, it will automatically shut down to prevent outside air enter the inside of the tank or water.
Q:What do you mean by manual butterfly valve DN100 D341X-10?
DN100 refers to the inside diameter of the butterfly valveD stands for butterfly valves3 represents the turbine drive4 represents the flange connectionThe 1 represents straight throughX is the representative of the Dengqen rubber seal10 represents the pressure of 1.0Mpa (10 kg)Manual butterfly valve, also known as turn over plate valve, is a simple structure of the control valve, but also can be used for low pressure pipe medium switch control. Butterfly valve refers to the closure of parts (valve or butterfly plate) as the disk, around the valve shaft to achieve rotation and closing of a valve, the main cut off on the pipe and throttling role. 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. 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:What's the size of the signal butterfly valve sleeve?
The signal valve of the fire door (not in the signal valve shutter doors, fire signal valve use: top fire signal butterfly valve with the valve opening and closing signal device, when the valve is closed by 25% (open degree 4/1), the signal device output signal was mistakenly closed to the fire control center. Therefore, this butterfly valve is the best matching product of automatic fire sprinkler system.
Q:Buried extension butterfly valve is buried directly, or need to repair the valve well?
The establishment of a repair valve well, easy to repair, usually hydrogen long rod butterfly valve installed in the well. But if the quality of buying long stem butterfly valve, it can also be buried directly, not easy to bad
Q:What does "10" in the butterfly valve "D71X-10" mean?
The pressure of 10 kg 1.0MPA is usually cast iron
Q:What does "D341X-16Q" mean?What do D341-16Q letters and numbers mean for butterfly valves?
D - valve type code: Butterfly valve;3 - valve drive mode code: worm gear;4 - valve connection form code: flange;1 - valve structure type code: vertical plate type;X - seat sealing surface or lining material code: rubber;16 - nominal pressure value: PN1.6MPa;Q - body material code: QT400 - 15.
Q:Butterfly valve in the use of the difference? Caliber?
Role of butterfly valveButterfly valve is to use disc type to open and close parts reciprocating reciprocating about 90 degrees to open, close or adjust the flow of medium valve. The butterfly valve has the advantages of simple structure, small volume, light weight, material consumption, installation of small size, the driving performance of torque is small, simple operation, rapid, high chemical corrosion, and can also have good flow control function and closure characteristics, the use of butterfly valve is very extensive. Its varieties and quantities are still expanding, and the development of high temperature, high pressure, large caliber, high sealing, long life, excellent regulation, as well as multi-function development of one valve. Its reliability and other performance indicators have reached a high level. Disadvantages, there is a certain resistance to the medium.Gate valves are more used in steam pipes and large diameter water supply pipelines, because of the general requirements of fluid resistance is small, the use of gate valve.Valve is hand wheel rotation, stem upward movement. Flow is not the same, the gate valve requires full open. Need a higher installation space, the valve sealing surface has a certain self sealing capacity, its spool by the media pressure closely with the valve seat sealing surface contact, 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.
Q:Electric butterfly valve (not take the lead) what do you mean?
Electric butterfly valve, as its name implies, consists of an electric actuator and butterfly valve, and the customer does not take the lead, that is, without the electric actuator, only the butterfly valve can be provided.
