Fireproof valve
Fire endurance of the valve is 120 min
The valve is intended for using in smoke removal system of ventilations of the buildings and buildings of the different purpose and is used in correspondence to SNIP 2.04.05 - 91. The valve can be fixed in horizontal and vertical opening barriering constructions of smoke valves, as well as on offtake branches, and is executed with one or two flanges. The valve is fixed inwardly in premiseses with warm-up ambience from -30С to +40С in the absence of direct influence of the atmospheric precipitation and condensations on damper. The valve KPV-2 is produced in в 2 modofications, depending on drive:
- with spring drive and heat lock on 72 С;
- the electromechanic drive Belimo (the Switzerland) and revocable spring.
The valve is not a subject to installation in premiseses of the categories А and B under explosion and fire risk and ambience, in which the agressive pair(vapour)s is contained and gases in concentration, destroying metals, paintwork covering and electric insulating.
The circuitry of the valve by means of the button on the body provides the autonomous opening of the damper for the checking of valve capacity to work.The scheme of valve construction KPD-2
- Body
- Thumb mechanism
- Mechanical drive
- Damper of the valve (open)
- Stress dampers
- Hatch for srvicing
- Heat-insulating bridge
- Axis rotations of the damper
- А - a height of the valve;
- В - a width of the valve;
- Х - a salient of the damper in valve at the input;
- Х1 - a salient of the damper on output from valve.
