Description
Technical field
The utility model relates to a kind of fire equipment, is specifically related to a kind of ventilating fire prevention valve.
Background technology
In air-conditioning or new wind ventilation shaft, in order to prevent fires, fire resisting damper is installed conventionally.Although traditional fire resisting damper can have fireproofing function, can not regulate new wind and air-conditioning according to indoor environment demand.In addition, after traditional fire resisting damper is installed, also need to install in addition the control valve of new wind and air-conditioning, both superpose after installation volume increase, take up room excessive, manufacturing cost rising, is also not easy to installation.Secondly, the insufficient sensitivity of existing fire resisting damper to fire prevention temperature, fire prevention is long actuation time, can not meet the new requirement of client.
For this reason, we have researched and developed a kind of Novel fireproof bivalve, are arranged in air-supply or air draft air supply duct, can play sensitive effective ventilating fire prevention effect, and new wind and the air-conditioning that can provide air-conditioning equipment again regulate simultaneously.When indoor breaking out of fire, while reaching 70 ° of C through the air themperature of fire prevention bivalve, fire prevention bivalve can start bolt down procedure, and whole pass valve process is no more than 1 minute.Adjusting by fire prevention bivalve to new wind and air-conditioning, can realize the control to room air freshness and temperature; In the time of indoor breaking out of fire, can effectively close ventilation, reduce spreading of fire, simultaneously outside transmission of electric signals.
Utility model content
The purpose of this utility model is in order to overcome the deficiencies in the prior art, provides a kind of more compact structure, reaction sooner, not only to have fire-proof function, but also can regulate new wind to be vented in the fire prevention bivalve of one.
The utility model is achieved by the following technical programs:
A kind of fire prevention bivalve, it is characterized in that: comprise new wind control valve and air-conditioning control valve, be arranged on fresh air pipeline, adjust in the threeway of joining with total pipeline in wind pipeline, described new wind control valve and air-conditioning control valve include motor, screw rod, guide pin bushing, valve plate, temperature sensor, control panel, on described motor output shaft, screw rod is housed, described screw rod is arranged on guide pin bushing inside, becomes spiral movable to be connected with guide pin bushing, and the end of described guide pin bushing is provided with the valve plate with sealing ring.
Further, described guide pin bushing is equipped with stroke lever, and described guide pin bushing top is provided with two travel switches that match with stroke lever, and described motor rear portion is provided with control panel, and described control panel is electrically connected with motor, travel switch, temperature sensor.
Further, described temperature sensor is arranged in air channel, adopts the heat-sensitive sensor of high sensitivity.
Further, described fire prevention bivalve is opening under normal circumstances, in the time that temperature sensor detects 70 ° of C high temperature, valve plate can be closed completely in 1 minutes, simultaneously outside output feedback signal, after described valve plate is closed completely, under 500Pa pressure, the inleakage in its valve plate unit are is less than 500m3/ (m2h).
Technique effect of the present utility model is as follows:
The utility model has adopted tune wind and new wind double-valve device, can regulate indoor temperature and room air freshness simultaneously, and temperature and room air freshness regulating effect are good; In the time fire alarm being detected, bivalve by Close All, can effectively be closed ventilation in 1 minute, reduced spreading of fire, simultaneously outside transmission of electric signals.The utility model adopts brand-new structure, by the Function Integration Mechanism of traditional fire resisting damper, air-conditioner temperature control valve, new wind control valve three valves together, there is fire prevention and regulate dual-use function, greatly reduced valve volume, take up room, reduce production cost, simultaneously also convenient installation.The utility model adopts heat-sensitive sensor, control panel, motor, helicoidal gear and the valve plate with sealing ring of high sensitivity, and compared with traditional fire resisting damper, higher, the fire prevention actuation time of being quick on the draw is shorter, flameproof effect is better.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In accompanying drawing: 1-threeway, 2-travel switch, 3-temperature sensor, 4-control panel, 5-motor, 6-screw rod, 7-guide pin bushing, 8-valve plate.
Detailed description of the invention
As shown in Figure 1, a kind of fire prevention bivalve, comprises new wind control valve and air-conditioning control valve, is arranged on fresh air pipeline, adjusts in the threeway 1 of joining with total pipeline in wind pipeline.New wind control valve and air-conditioning control valve include motor 5, screw rod 6, guide pin bushing 7, valve plate 8, temperature sensor 3, control panel 4.Motor 5 is fixedly mounted in pipeline, screw rod 6 is housed on its output shaft, and described screw rod 6 is arranged on guide pin bushing 7 inside, and is connected with 7 one-tenth screw pairs of guide pin bushing, the end of guide pin bushing 7 is installed with the valve plate 8 with sealing ring with bolt, and sealing ring and valve plate 8 all adopt fire proofing material to make.On guide pin bushing 7, stroke lever is installed, guide pin bushing 7 tops are provided with two travel switches 2 that match with stroke lever.
When not occurring under fire alarm, normal operating conditions, can drive screw rod 6 to rotate by starter motor 5, screw rod 6 drives the guide pin bushing 7 left and right rectilinear motions that become with it spiral to coordinate, and described guide pin bushing 7 drives 8 side-to-side movements of the valve plate with sealing ring that are fixedly mounted on its end, realizes regulation.The air-conditioning control valve of fire prevention bivalve is connected with air-conditioning coil pipe air supply duct, by regulating valve plate 8 apertures of air-conditioning control valve, Air Conditioning flow is changed, thereby realize the adjusting of indoor temperature; The new wind control valve of fire prevention bivalve is connected with the first road of air conditioner fresh air ajutage, by regulating the aperture of new wind control valve valve plate 8, air conditioner fresh air flow is changed, thereby realizes the adjusting that room air is fresh.
