New generation valve aerodynamics implementer
At/sr/rt pneumatic valve actuator
Kfffi's new (at/da/rt/sr series) valve aerodynamics implementer is the implementing agency that converts the incoming pressure signals to 90 degrees and then reverses the rectangular output. The series of aerodynamics is a small, high-performance implementation structure, divided into two-gas and monogas controls, which can be used in combination with an angular processor control valves in the event of regulation and switches, as well as in other reverse motion settings。
Kffki (at/da/rt series) description of the two-role valve aerodynamic implementer type (for information):
First, the twists required for valve openings and closings are determined, with a recommended safety factor of 15 to 20 per cent under normal-use conditions. Add safety values based on the fluid medium used in the valve. A 20% safety increase for cleaning, lubricating media; a 25% safety increase for water vapour or non-lubricant liquid media; a 40% safety increase for non-lubricated slurry liquid media; and an 80% safety increase for non-lubricant particulate media. When you select a two-gas control implementer, you can get an accurate at model based on the above calculated twist value and a table of the two-gas control implementer using the source pressure。
Kff kofi new (sr series) single function (spring double) avp model description (for information):
When selecting a single-gas control implementer, the exact sr model is obtained when the end point is found in the spring retour column based on the above calculated value and the use of the source pressure. For example, the gas source pressure is zero. 4mpa, based on the above calculation, requires control of a twist of 165n. The valve for m begins with a table to find the end point of the spring complex with a close twisting 171n. M and then looks left to see the implementer model sr160 (with a total of 10 springs)。
Note: in the sr monogas control output twist table, the spring recoil "end" is the twist that closes the valve and the spring recoil "starts" is the twist that opens the valve. Correlation at the beginning of the corresponding gas source pressure is the twist at the closing of the valve state, and at the end of the gas source pressure the twist at the opening of the valve。
Main structural characteristics of kffki's new valve aerodynamic implementer
(1) aluminium alloy cylinders, which are compacted, oxidized, hard on the surface and hard to grind。
2) tight double piston gears, cog-shaped structures, condensed precision, smoothing, symmetry of position, and constant rectangular output。
3) pistols, rodents and output axes are equipped with f4-directed rings to achieve low friction, long life and avoid metal contact。
4. The casks, end covers, output axes, springs, fast fixes, etc. Have been decorated。
5) mono-gas control dispensers are pre-pressured with springs that can be safely and conveniently dismantled and assembled。
6. The at aerodynamic executors (at) can perform two-way process adjustments of 0 degrees and 90 degrees positive and negative 5 degrees at full- and all-off locations。
7. Installation of connective dimensions in accordance with iso 5211, din 3337 and vd1/vde 3845 and numar standards to ensure the interchange between at aerodynamic executors and to facilitate the installation of attachments such as electromagnetic valves and limit switches。
8) the installation of the main axes has multiple shapes (quadrant, axle, flat hole) for choice
9) appearances and fineness, light weight and waterproof seals。
10) with constant, high, low temperature. Use of rubber under constant working conditions and use of fluorine or silicon rubber at high or low temperatures
