Abstract
The utility model relates to an electric reset valve controller for an anti-fire valve and an exhaust smoke valve. The existing ratchet pawl positioning valve controller for an anti-fire valve and an exhaust smoke valve does not have a quick-opening function; after a valve is closed, the controller can not be started immediately to open the exhaust smoke valve under the condition that a fuse is not recovered; a reset motor of the utility model is connected with a positioning rotary disc through a gear reduced drive device to cause a pull rod whose one end is flexibly connected with the positioning rotary disc to pull the ratchet wheel; after a fire is extinguished, the fuse does not need to be recovered on a job site, the exhaust smoke valve is opened immediately to exhaust poisonous high-temperature smoke.
Description
The utility model belongs to ventilation, fire-protection equipment field, particularly relates to the valve positioner of a kind of fire-closing valve and exhaust smoke valve.
The valve positioner of fire-closing valve of the prior art and exhaust smoke valve comprises the slide plate and the position limit switch of casing, click positioning means, fuse sheet mechanical type fus, electromagnet, pulling pawl plate.Use sort controller in ventilation, fire protection engineering, during breaking out of fire, the fus action causes the valve positioner action, closes the fire and smoke exhaust valve, comes into effect alkyl halide extinction using gas or other fire extinguishing measure.After fire extinguishing finishes, because high temperature and flue gas still exist, temperature sense signal is not removed, personnel can't carry out associative operation near valve, start-up control device immediately, make it open the fire and smoke exhaust valve immediately, cause poisonous high-temperature flue gas to be trapped in the building, can not get rid of rapidly, after must waiting the high temperature flue gas to eliminate, manually change fuse sheet, after the normal state of recovery fus, just can open valve and make the system recovery proper functioning, make halon extinguishing system and other suppression system rational function of use of can not bringing into normal play.
The purpose of this utility model provides a kind of with the anxious electronic replacement controller of opening function, can be after fire suppression, and the remote control valve controller resets immediately, drives valve open, discharges poisonous high-temperature flue gas rapidly.
The utility model band is anxious, and to open the technological scheme of electronic replacement controller of function as follows:
It comprises the output shaft of casing, click positioning means, fus, electromagnet, position limit switch, connection ratchet, the output shaft pusher dog and the control circuit of drive valve switch, it is characterized in that:
Be provided with the anxious electronic resetting-mechanism of opening in the casing, this mechanism is by motor connection gear speed reduction gearing and the location rotating disk that is connected gear reduction transmission device final stage of resetting, one one end and location rotating disk are flexibly connected, and the pull bar of the band not-go-end that the other end is connected with ratchet is limited in ratchet in 90 ° of circular arc scopes that make valve closing and unlatching and rotates;
Reset the unlatching of motor by far away from the control of the reset switch of control centre, reset motor by temperature sense path sensitive switch and the control of rotating disk path sensitive switch two-way, wherein, the temperature sense path sensitive switch that the motor that resets cuts off the power supply in fuse sheet fusing back is positioned at by the fus, and the rotating disk path sensitive switch that the motor that resets is cut off the power supply behind valve opening is positioned at location rotating disk one side.
There is with holes taking off post above-mentioned location on the rotating disk limit, and pull bar passes and locatees rotating disk and is slidingly connected from the hole that takes off post.
Have gap on the rotating disk of above-mentioned location, the contact of rotating disk path sensitive switch is disconnected.
The said gear speed reduction gearing is Pyatyi gear reduction transmission, and first gearwheel is meshed with gear on the motor, and the final stage small gear is meshed with location turntable shaft gearwheel.
Working procedure of the present utility model; In peacetime, valve opening, controller are in normal reset mode.When fire takes place, the fuse blows of valve positioner, because the pull bar not-go-end is in the far-end state with taking off post, the click positioning means moves valve closing.After fire extinguishing finished, because high temperature and flue gas still exist, temperature sense signal was not removed, and personnel can't recover fus near valve.At this moment, the remote control reset switch, by alternately connecting of first position limit switch and rotating disk position limit switch, the motor that resets is rotated, driven gear speed reduction gearing and location rotating disk, the pull bar pulling ratchet that connects on it is rotated counterclockwise, when turning to valve opening state, because this moment, fus did not recover, temperature sense path sensitive switch is in off state, the gap of location rotating disk just in time disconnects rotating disk path sensitive switch, and the motor stall resets.At this moment, take off post and pull bar be in the motion dead point on, clockwise elastic recovery moment of torsion on the output shaft still can't make output shaft rotate, if with the dead point deviation to some extent of moving, also can be because of the amplification of reducing gear to friction torque, make the elastic recovery moment of torsion that output shaft is rotated, make valve remain on opening state, discharge poisonous high-temperature flue gas rapidly.After recovering fus, by a reset switch, controller promptly returns to normal reset mode again.
The utility model has the advantages that: owing to have the anxious function of opening, this valve positioner can be after fire suppression, and the remote control valve controller resets immediately, drives valve open, discharge rapidly poisonous high-temperature flue gas, make control system safer, reliable, realize far distance automatic controlling.Be applicable to the suppression system in the fire protection engineering.
