Swing inspection hatch

Swinging hatches can operate at the sub-pressure and at the over-pressure side of an installation – it depends on type of applied solution (hatches without a drive at the sub-pressure side, hatches with a drive at the sub-pressure / overpressure side). Standard device we offer is a double hatch. Double swinging hatch without a drive Device comprises a body and inlet and outlet flanges (square section). Inside the body there are two throats, through hole of which is closed by means of rotary hatches. They are equipped with levers with metal loads on them. Dusts, which go through the device, because of its weight, open the first hatch and, after closing it, another one. Synchronization of opening of the hatches and pressure on the throat is adjusted by relevant setting of loads on both of the hatches. Double swinging hatch with a drive In case of this solution there takes place enforced synchronization of swinging hatches opening. It takes place by means of motor-reducer assembly on axis of which there are fastened special cams. Their movement warrants setting of hatches – while one closes upper throat, the second one is open and vice versa. Such operation warrants 100% removal of dust without decompression. In case of a few solutions and additionally, in case of limited space, apart from double-hatch we apply
