Abstract

A remote smoke-discharging valve actuating mechanism comprises a wiring terminal fixed both on a casing and the bottom board of a panel, an inching switch, a connector lug base, a cable pulley, a pendulum support, an electromagnet, and a pendulum bar assembly, and the bottom board is further fixed with a shaft with a button, a torsion spring and a button sleeve of a pressing ring, wherein the end of the shaft with a button is fixed with a button, the rocking bars of the rocking bar shaft are respectively engaged with the pendulum bar and the pressing ring in order to form a button assembly, the panel is further connected with a flip lid, the engagement of a fixed shaft and a rotation shaft is connected with a seal ring. When the flip lid is closed in peace time, dust and foreign body do not drop in the casing and alarm by mistake. When the fire alarm is alarming, the flip lid is quickly opened by hand instead of a tool, the button is pushed, thereby the ratchet wheel releases the click, the smoke-discharging valve is transitively opened and discharges smoke through a steel cable with the function of the valve extension spring, thereby achieving simple and convenient operation, and winning precious time for the fire insurance salvation. The O-shaped seal ring can avoid the entwining phenomenon caused by the fast release of the steel cable. The installment hole of the foursquare screw of the panel is arranged with a small cap closure, thereby realizing more beautiful and practical appearance.

Description

Remote exhaust smoke valve actuator

Technical field

The utility model relates to a kind of being installed on the leafy smoke exhaust port of tall building, board-like smoke exhaust port, the air blowing opening etc., be used for remote manually or the electrical signal remote exhaust smoke valve actuator that opens that the valve smoke evacuation uses.

Background technique

Patent No. CN98246702.8 " the fire-closing valve actuator of discharging fume at a distance " is though also provide a kind of remote operated actuator, but also top panel need be disassembled in use, take away panel, could insert in the moving hole of plate with spanner or tablet again, carry out open operation, troublesome poeration, slow, the use inconvenience of speed.

Summary of the invention

Technical problem to be solved in the utility model is: a kind of remote exhaust smoke valve actuator is provided, and beautiful shape, practical, simple, convenient, for smoke evacuation rapidly gains time, use safer, reliable.

The technical scheme in the invention for solving the above technical problem is: remote exhaust smoke valve actuator comprises the wiring terminal, sensitive switch, the wiring headstock that are fixed on casing, the panel inner bottom plate; The rope sheave dish, the ratchet that have rotating shaft, dead axle, by on ratchet and the rocker with the click-fit that is connected on torsion spring, the pawl axis, also be connected with dead man, fine motion stage clip on the rocker, by rocker screw, torsion spring, be fixed on the rocker seat; Rocker also be fixed on base plate upper pendulum bar seat on be connected with fork screw, torsion spring fork cooperate, fork is connected with electromagnet; Also include by the button cover that is fixed with band push button shaft, torsion spring, trim ring on the base plate, the button axle head is fixed with button, and the rocking bar on the rocker shaft cooperates the button assembly that constitutes respectively with fork, trim ring; Also be connected with mobilizable renovating on the described panel, also be connected with seal ring with the rotating shaft cooperation place on the described dead axle.

Compared with prior art, advantage of the present utility model is: former panel is directly to be screwed on casing, need during use panel is disassembled and could operate, troublesome poeration, speed is slow, on the panel neutral position mobilizable renovating is installed now, this renovates at ordinary times and closes, dust, foreign matter can not fallen in the casing, can false alarm yet, and when fire alarm, just can open rapidly with hand without instrument and to renovate, just can press button at once easily, make fork throw off rocker, ratchet is thrown off ratchet, under the effect of valve extension spring, opens the exhaust smoke valve smoke evacuation by the Steel Cable transmission, simple to operate, convenient, for the quality time is won in the fire relief.Also be with O-ring seals with the cooperation place of rotating shaft in the draw-in groove of dead axle, damping function is played in the rotation of countershaft, prevents the wrapping phenomena that causes when fast unclamping because of Steel Cable.On the panel except that be equipped with renovate, also tegillum is installed and seals at four jiaos of screw mounting hole places, make the profile of this actuator more attractive in appearance, more practical, reach the requirement of panel international standard.
