Sprinklers of standard and usual speed of the V27 model have the hemispherical form of dispersion, are suitable for standard commercial use.
Are offered with flasks of the standard and increased speed. The sprinkler of usual speed of the V27 model has the hemispherical form of dispersion, a half of the sprayed liquid directs upward to a ceiling and other half down. It can be established in vertical or suspended position. The modern design in the form of a fragile glass flask reacts to heating (the standard or increased speed) with fast and exact operation.
The frame cast under pressure more streamline and attractive, than traditional frames,
cast in forms from sand. Molding has the turnkey six-sided thickening allowing to tighten it under different corners and facilitating installation. This sprinkler is offered in various temperature executions and with different coverings according to constructive requirements.
Operation of a sprinkler
The working mechanism is the glass flask, with the liquid reacting to heating. During the fire ambient temperature increases, forcing to extend liquid in a flask. When ambient temperature reaches the settlement temperature of a sprinkler, the flask collapses. As a result the conduit is exempted from the condensing details, and water is issued via the deflector. The deflector is executed so that the form of spraying of water allowed to extinguish fire in the most effective way.

Victaulic (Viktolik, Viktaulik) - bessvarny connection, pipeline fittings.
ADVANTAGES: There is no DANGER of IGNITION As the method Viktolik (Viktaulik) is exclusively mechanical bolted connection, there is no danger of ignition at its application. It much more safely also does not demand shielding or tracking fire.
ASSEMBLY EASIER AND DEMANDS LESS BOLTS, THAN the FLANGE Connection CONNECTION at the expense of trailer grooves demands everything on two bolts for each coupling (with a diameter up to 323,9 mm). Coaxiality of bolted openings is not critical, as at flange connections. Also it is not necessary to spend time for adjustment of details, and time spent for assembly of designs considerably is reduced.
It is ECONOMIC AND PRACTICAL Assembly by method Viktolik takes five times less time, than welding, a flange or threaded connection, application of this method reduces a total cost of installation by 20-40%. Cost pays off more precisely; terms of performance are defined more specifically.
FLEXIBILITY System Viktolik (Victaulic) is unique on the ability to allow expansion, compression and a deflection that gives the chance at design to use these characteristics, applying the published standard products. As a result, among possible options - an exception or reduction of the special additional equipment for decrease in vibration, loopback pipe compensators and a close tolerance.
DURABILITY In need of connection of standard pipes, a fitting and valves with trailer grooves, durability can be reached for счëт use of standard couplings. The patented unique design of the rigid ZeroFlex coupling from stainless steel or malleable cast iron, thanks to the edges which are cut off obliquely, provides sufficient fixing of a pipe for counteraction to the twisting and bending loadings.
ABSORPTION of SEISMIC FLUCTUATIONS Reliable fixing of wedges (edges) of couplings in grooves on all circle of a pipe allows a design to maintain the considerable pressure and face loading and resists to shifts of pipes as a result of influence of various internal and external factors.
VARIOUS LAYING (CONSOLIDATIONS) FOR VARIOUS APPLICATION As laying (consolidation) - only of connecting parts, adjoining with transferred on the pipeline Wednesday, they can be used with standard couplings, according to necessary requirements. EPDM, a gidrina and so forth materials are made of ftorelastomer.
It is SIMPLE to LEVEL a connection Method by means of trailer grooves full rotation of pipes, valves, a fitting and couplings before a fastening allows that allows to compensate some errors at alignment and relieves of need of production of two openings necessary for flange connection. Installation in hard-to-reach spots is facilitated.
COMPENSATION of NOISE AND VIBRATION the Basic design of the separate pipes with trailer grooves condensed with rubber laying and recorded by the coupling collars which are pulled together outside with bolts reduces transfer of noise and vibration in system by the geometrical principles. Independent tests confirmed considerable attenuation of vibrations.
EASY ACCESS TO SYSTEM AND the EQUIPMENT Dismantling (for what it is necessary to remove only four bolts) provides access to system for cleaning, service, addition or replacement of details. Throttle valves Viktolik provide a possibility of service of the equipment or systems by means of their isolation with a deaf cut-off.
