Q:What are the advantages and disadvantages of the two functions of the pneumatic ball valve actuator?
From the above work principle can be seen: double acting pneumatic actuator, valve opening and valve closing all need compressed air thrust to perform. That is to say, the pneumatic actuator will remain in a position in case of loss of air.The single acting actuator belongs to the automatic reset type. After losing the continuous air pressure, the actuator will drive the valve back to the initial setting position under the tension of the spring.This answer is recommended by users
Q:Advantages and disadvantages of ball valves and scope of application?
Ball valve through the circular channel and smooth, compact ball valve, so the fluid through its resistance is very small (strong circulation). Quick and quick opening and closing, easy installation and more connection. Wide range of use. Its shortcomings, high cost.
Q:Calculation formula of ball valve flow
Q=Cd*A* (2*delta_P/rou) ^0.5Among them, Cd is the flow coefficient, generally take 0.6~0.8, you can go to check informationA is the opening areaDelta_P is the differential pressure between the inlet and outlet of the ball valveRou is the density of the fluid
Q:The difference between gate valve, ball valve and butterfly valve
Butterfly valve plate and the ball valve is rotated around its own axis for movement; valve plate valve for the lifting movement along the axis; butterfly valve and gate valve can adjust the flow through the opening; the ball is not easy to do this.1. The sealing surface of the ball valve is spherical2. The sealing surface of butterfly valve is circular cylindrical surface3, the sealing surface of the gate valve is flat.
Q:Difference between fireproof and antistatic ball valve and ordinary ball valve
Fire valve is generally aimed at soft sealing material valve, that is, after the fire on the valve, the ball valve can rely on medium force and metal valve seat (body) contact, to achieve sealing, so that the fire does not go down the pipeline. Anti-static valve is for soft sealing material of the valve, when the ball switch and soft seal friction, will produce static electricity, if the pipe is taking the flammable and explosive medium is very dangerous, so the valve will set a device outside the sphere will Unicom electrostatic oriented, to prevent static electricity.Generally like the market valve, a little better quality, they are the default valve is fire, anti-static, the production costs of these two types of valves is bad, at most two or three dollars, which is still much.
Q:What is the difference between ball valve and plug valve?
The main advantages of plug valves are as follows:Suitable for frequent operation, quick and easy opening and closing.Fluid resistance is small.The utility model has the advantages of simple structure, relatively small volume, light weight and convenient maintenance.Good sealing performanceFree from the direction of installation, the flow direction of the medium can be arbitrary.No vibration, little noise.Plug valve installation and maintenance should pay attention to the following matters:Leave the valve handle in a rotating positionCannot be used as throttling.
Q:Ball valve specifications 1/2 inches corresponding to DN?
I know that. 1/2 stands for DN15. 3/4 stands for DN20. Ha ha, unfortunately no points
Q:PPR ball valve diameter is 3 cm, what is the specifications?
The PPR32 ball valve with the DN25 is a specification. (DN25 is the nominal diameter of the pipe and PPR32 is the outer diameter of the pipe)The PPR25 ball valve with the DN20 is a specification.
Q:Heating live catch valve DN15 straight DN15 angle what does that mean?
It's DN15 positive three way live ball valve.
Q:Is the two piece ball valve in the direction of the pressure pipe?
Compression capacity is not as good as two, but better than the three chip. A ball valve has the advantages of low cost, low price; the two valve is the three products in the most excellent in resistance and flow, the valve inside is preferred; features three ball valve design structure is easy to install, because the three ball valve can be installed by dismantling during installation, so in different pipeline even some other connections are completely no problem, fast loading, thread, flange, welding and so on, so the market is the most complete connection number of ball valve, especially when welding, a chip ball valve and the two valve can not be opened due to installation, want to welding in the pipeline it would be easy to the inside of the PTFE (similar to plastic) in a burnt out, the best choice at this time is three piece ball valve. But the disadvantage of three piece ball valve is the poor compression ability.
