Abstract

The utility model relates to a gear wheel type electric replacing mechanism of smoke and fire prevention valve. The utility model is characterized in that a decelerating gear wheel group connected with a generator is composed of two groups of gear wheels, and the interspace between the two groups is meshed through a gear wheel arranged on a swinging arm. One end of the swinging arm is provided with a slot appearing the converse 7 shape, and a locking pin shaft for locking the swinging arm is fixed on a locking board. The lower end of the locking pin shaft is arranged in the slot hole of the swinging arm, and the upper end is sleeved with a release locking push rod which is provided with a pulling spring. A gear wheel of one group gear wheel near to the generator is installed with a plurality of pins, and the pins and the release locking push rod form the match of ratchet wheel and pawl type. For the utility model controls the valve closure and replacement by the meshing and separating of the gear wheel group near to the generator end and the gear wheel group near to the valve main shaft end through the swinging arm, the electromagnet is eliminated, which makes the structure simple and enhances the reliability of the executive mechanism.

Description

The electronic Smoke proofing and fire proofing valve system that resets of gear type

Technical field

The utility model relates to the electronic Smoke proofing and fire proofing valve system that resets of a kind of gear type, belongs to the fire-fighting series products.

Background technique

Electronic position restoring Smoke proofing and fire proofing valve system, be installed on the main shaft of steel valve one Side, when safe, be opening state, when fire takes place, by fire control centre, the electromagnet in mechanism send electricity, and electromagnet gets electric adhesive, valve is closed rapidly or fuse blows or with manually making valve closing, after fire is eliminated, give electricity by control centre, motor rotates and makes valve be reset to opening state again.Used this mechanism adds one group of motor and reduction gear on the basis of common Smoke proofing and fire proofing valve system at present, with a connecting rod spindle arm is pulled to reset, and during release, gets electric adhesive by electromagnet and takes off lock.Its shortcoming is to reset to adopt different power sources with closing, and closing needs use electromagnet, makes complex structure, and electromagnet core is corroded easily, influences the reliability of actuator.

Summary of the invention

The purpose of this utility model is in order to overcome the shortcoming of prior art, a kind of electronic Smoke proofing and fire proofing valve system that resets of gear type that does not have electromagnet to be provided.

The technical solution of the utility model is finished like this, a kind of by motor, train of reduction gears, mainshaft gear, the electronic Smoke proofing and fire proofing valve system that resets of gear type that fus is formed, be characterized in, the train of reduction gears that is connected with motor is made up of two groups of gears, be meshed by the gear that is equipped with in the swing arm between two groups of gears, swing arm one end is equipped with the groove that is down " 7 " font, the locking bearing pin of locking swing arm is fixed on the lockplate, locking bearing pin lower end is in the slotted eye of swing arm, its upper end is set with takes off the lock push rod, take off the lock push rod and be equipped with extension spring, on the gear near one group of gear of motor side many pins are housed, pin constitutes cooperating of " click " formula with out of stock push rod.

Because the utility model is to make near the gear train of motor side with near the engagement of the gear train of valve spindle end with throw off closing and resetting of control valve by swing arm, removes the electromagnet that disappeared, make simple in structurely, the reliability of actuator is improved.
