Description

Check valve with driving motor

Technical Field

The utility model belongs to the technical field of the check valve, concretely relates to check valve with driving motor.

Background

The check valve is a valve with a circular valve clack and acts by self weight and medium pressure to block the medium from flowing backwards. It belongs to the automatic valve category, also called check valve, reflux valve or isolation valve. The valve clack motion mode is divided into lifting type and swing type. The lift check valve is similar in structure to the stop valve and only lacks a valve rod that drives the valve flap. The medium flows in from the inlet end (lower side) and flows out from the outlet end (upper side). The valve is opened when the inlet pressure is greater than the sum of the weight of the flap and its flow resistance. Otherwise, the valve is closed when the medium flows backwards. Swing check valves have a flap that is tilted and can pivot, and operate on a similar principle to lift check valves. The check valve is also comparatively common on smoke ventilator, and the check valve on the smoke ventilator is at the in-process that uses, because the unstability of air current makes the valve block open easily, causes the oil smoke to flow backward and gets into indoorly, and general check valve is not convenient for lift the maintenance off from smoke ventilator moreover.
