Abstract
The utility model relates to an actuator for the smoke exhaust and fireproof valves; which is a valve actuator used for ventilation and air conditioning pipeline, and for combination with the actuator of smoke exhaust valve. The utility model is characterized in adopting two torsional springs with reverse winding direction instead of the two extensional springs of the original actuator, wherein, the hook at the tail end of a swing rod is hung on the core rod of a temperature fuse. When the fuse sheet is broken, the hook of the swing rod is released, and the swing rod is rotated clockwise under the action of an external spring, then the valve is closed to prevent the smoke from spreading along the pipeline. The utility model has the advantages of novel, simple, and compact structure, and safety and reliability, and is a novel actuator for the smoke exhaust and fireproof valves with economy and practicability.
Description
Technical field
Smoke evacuation fire-protection valve final controlling element described in the utility model, be a kind ofly be used to ventilate, the valve actuator of air-conditioning duct, be and the use that forms a complete set of of exhaust valve final controlling element to constitute smoke evacuation fire-protection valve final controlling element.
Background technique
The smoke evacuation of domestic production at present fire-protection valve uses the fire-closing valve final controlling element, is to finish twice holding function that the smoke evacuation fire-closing valve needs with two extension springs.Because of this final controlling element uses extension spring, make that the structural plan size is bigger.When valve hour, difficulty is installed.And the adjustment of two extension spring pulling force balances is difficulty.Member needs assembled in situ to make, and makes troubles to installation.And appearance quality is poor.At existing problem in the prior art, a kind of novel smoke evacuation fire-protection valve final controlling element of research and design, existing problem is very necessary in the prior art thereby solve.
Summary of the invention
In view of existing problem in the above-mentioned prior art, the purpose of this utility model is a kind of novel smoke exhaust fire-protection valve of Development and design final controlling element.This final controlling element adopts two torsion springs to replace two extension springs of original final controlling element, and all parts are assembled into an integral body, does not use assembled in situ and makes.Smoke evacuation fire-protection valve final controlling element described in the utility model is between mandrel and support inner spring to be housed, inner spring is enclosed within on the mandrel, outside support, be set with outer spring, support is connected by screw with the axle head of fork, fork is contained between the axle sleeve and circlip for shaft of mandrel, axle sleeve is connected with Cock screw with the valve sharf, and the tail end and the hook of fork are riveted together, and hang on the core bar of temperature safety fuse.One end of inner spring described in the utility model is fixed on the axle sleeve, the other end is in support; One end of outer spring hangs on the fork, and the other end is fixed on the valve housing; Inner spring and outer spring are around to opposite.The base of temperature safety fuse described in the utility model is welded on the valve housing, and temperature fuse is fixed on the base.The utility model needs and the supporting use of exhaust valve final controlling element, could constitute the function of a complete smoke evacuation fire-protection valve final controlling element.The utility model provides a kind of novel smoke evacuation fire-protection valve final controlling element.Because of using two torsion springs to replace original two extension springs, the overall structure size is dwindled, be convenient to install and use and keep in repair.The utlity model has novel structure, simple structure, volume is little, exquisiteness is attractive in appearance, be convenient to installation and maintenance, advantage such as safe and reliable.It puts goods on the market in enormous quantities and will produce positive social benefit and remarkable economic efficiency.
Description of drawings
The utility model has two accompanying drawings, wherein
Accompanying drawing 1 smoke evacuation fire-protection valve final controlling element front view
Accompanying drawing 2 smoke evacuation fire-protection valve final controlling element plan views
Among the figure: 1, fork 2, hook 3, core bar 4, temperature fuse 5, base plate 6, base 7, outer spring 8, inner spring 9, axle sleeve 10, circlip for shaft 11, support 12, valve sharf 13, mandrel 14, valve housing
Embodiment
Specific embodiment of the utility model as shown in drawings, fork 1 is contained between the axle sleeve 9 and circlip for shaft 10 of mandrel 13, between mandrel 13 and the support 11 inner spring 8 is housed, and inner spring 8 is sleeved on the mandrel 13, one end of inner spring 8 is fixed on the axle sleeve 9, and the other end is not in support 11.The tail end of fork 1 is riveted together with hook 2.Outer spring 7 is sleeved on support 11 outsides, and the one end hangs on the fork 1, and the other end is fixed on the valve housing 14.Valve sharf 12 passes from mandrel 13 centers, and axle sleeve 9 and valve sharf 12 are connected by Cock screw.Temperature fuse 4 is loaded on the base 6 that is welded on the valve housing 14, and the hook 2 of fork 1 hangs on the core bar 3 of temperature fuse 4.Base plate 5 is buckled in top and is screwed on valve housing 14.Because of the utility model needs and the supporting use of exhaust valve final controlling element, thus base plate 5 above leave 4 screws, the exhaust valve final controlling element is installed is used.Rotate counterclockwise swing fork 1 during reset operation of the present utility model earlier, hook 2 is colluded on the core bar 3 of temperature fuse 4.The valve blade was in and opened to 90 ° and locate this moment.Auxiliary-handle with the exhaust valve final controlling element clockwise rotates 90 ° then, and the valve blade is closed again, finishes the work of resetting.When fire took place, the DC24 that the controlled center of the electromagnet of exhaust valve final controlling element is sent here lied prostrate electronic work, and the action of exhaust valve final controlling element is opened the valve blade again and discharged fume.When the Fire Smoke Temperature of discharging by valve reaches the fusing-off temperature of temperature fuse 4, fuse link fusing, in the core bar 3 retraction fuss 4, hook 2 is released.Fork 1 clockwise rotates under the effect of outer spring 7, drives the valve blade and closes for the second time, and the blocking-up fire smoke spreads along air conduit.
