Q:Three electric ball valve type T and type L what is the difference?
Electric three way ball valve is a kind of valve, can be divided into L and T type.The T type can cause three orthogonal pipes to connect with each other and cut off third channels, thus diverting and merging the channels.Two pipeline L three ball type valve can only be connected mutually orthogonal, communicating with each other while maintaining the third pipeline, only as a distribution function.Type T and L type reversing diagrams are as follows:Turn left and turn right |
Q:What are the advantages and disadvantages of the two functions of the pneumatic ball valve actuator?
The working principle of the single action mode:When the air pressure from the air intake (2) between the two piston into the cylinder cavity, the two ends of the cylinder piston moves to the separation direction, forcing the ends of the compression spring, both ends of the air chamber air through the air intake (4) discharged, while making two piston rack synchronous drive output shaft (gear) counterclockwise. In the air pressure through the solenoid valve for cylinder piston to move backwards, two to the middle direction in the spring, the middle air cavity air from the air outlet (2) discharged, while making two piston rack (gear) synchronous drives the output shaft to rotate clockwise. (if the piston is mounted in opposite directions and the spring is reset, the output shaft becomes reverse rotating, i.e., single acting reverse type)
Q:What's the difference between a hot melt ball valve and a ball valve in general? What's the use of it?
In general, both sides of the ball are wire interface, and hot melt ball valve on either side or side of the live connection with PP-R short tube, as a hot melt interface, so called hot melt ball valve. As for the use, there is no obvious difference, but the connection is different.
Q:Hard sealing ball valve, what method can calculate the leakage?
Generally requires V level, but for some valves, meters will purchase higher level. For engineering inspection, the bubble method is used.Valve leakage level has six levels, the highest level six, is often called a zero leakage.
Q:What's a twin hot melt ball valve?
Is a plastic ball valve, connecting France is hot melt.
Q:One piece ball valve, two piece ball valve, three piece ball valve, respectively, under what circumstances?
A piece of ball valve is mainly manual, two piece ball valve for atmospheric pressure and high pressure, three pieces of ultra high pressure will be used, according to the actual caliber to determine
Q:How to distinguish between cold water valve and hot water ball valve?
By the way, do you only require the working medium of the valve, general cold water and hot water?;Can provide the next 1, the valve's general use temperature of 2, whether the media granular impuritiesBoiling hot water is only 100 degrees; general, general valve can reach this use conditions,So cold water and hot water can choose the same type of valveI think the valve you want to know is not the drinking water valve you use at school?
Q:Which is the smallest flow valve, globe valve or butterfly valve? Which one is the biggest?
Ball valve with minimum flow resistanceStop valve flow resistance maximum
Q:What are the use of all - way ball valves and reducing ball valves respectively? What are the advantages?
Ball valves used for conveying viscous, easily slagging medium piping shall be of all sizes, allowing regular blow through of wax scraper. Used to transport gas or physical properties similar to the water medium of the pipeline should be used to reduce the diameter of the ball valve, because its weight than the full diameter of the ball valve about 30%, is conducive to reducing pipeline load and reduce costs.
Q:How many points of the ball valve, corresponding to a bit valve?
No detailed conversion forms are required. How many inches is the representation of inches?.In English, 12 inches are 1 feet, 1 inches =8 cents.So: 1/2 "ball valve, =4 sub ball valve, 1/4" ball valve, =2 sub ball valve, 3/8 ball valve, =3 sub ball valve, and so on.Just a simple conversion relationship.
