Abstract
The invention relates to ventilating fireproof equipment, in particular to a fireproof single valve. The fireproof single valve is formed by a motor, a threaded rod, a guide sleeve, a valve plate and a temperature sensor. The threaded rod is installed on an output shaft of the motor, installed in the guide sleeve and spirally and movably connected with the guide sleeve, and the valve plate with sealing rings is arranged at the end of the guide sleeve. The fireproof single valve has the functions of ventilation, fire prevention and air conditioner air regulation, and is complete in function, small in size and high in intelligentization degree.
Description
Technical field
The present invention relates to a kind of fire protection equipment, be specifically related to a kind of ventilating fire prevention valve.
Background technique
In pipeline for giving wind for air conditioner, in order to prevent fires, fire-closing valve is installed conventionally.Although traditional fire-closing valve can have fireproofing function, can not to air-conditioning, adjust according to indoor environment demand, need to install in addition the modulating valve of new wind and air-conditioning, both superpose after installation volume increase, take up room excessive, manufacture cost rises, and is also not easy to install.
For this reason, we have researched and developed a kind of Novel fireproof single valve, are arranged in air-supply or exhaust duct, can play sensitive effective ventilating fire prevention effect, can regulate air-conditioning again simultaneously.When indoor breaking out of fire, when the air temperature of process fire prevention single valve reaches 70 ° of C, fire prevention single valve can start bolt down procedure, and whole pass valve process is no more than 1 minute.Adjusting by fire prevention single valve to air-conditioning amount, can realize the control to indoor air freshness and temperature; When indoor breaking out of fire, can effectively close ventilation, reduce spreading of fire, simultaneously outside transmission of electric signals.
Summary of the invention
The object of the invention is in order to overcome the deficiencies in the prior art, provide a kind of more compact structure, reaction sooner, not only to there is fire-proof function, but also can regulate the fire prevention single valve that is vented in one.
The present invention is achieved by the following technical programs:
A kind of fire prevention single valve, it is characterized in that: comprise motor, screw rod, guide pin bushing, valve plate, temperature transducer, control panel, on described motor output shaft, screw rod is housed, described screw rod is arranged on guide pin bushing inside, become spiral movable to be connected with guide pin bushing, the end of described guide pin bushing is provided with the valve plate with seal ring.
Further, described guide pin bushing is equipped with stroke lever, and described guide pin bushing top is provided with two position limit switches that match with stroke lever, and described motor rear portion is provided with control panel, and described control panel is electrically connected to motor, position limit switch, temperature transducer.
Further, described temperature transducer is arranged in air channel, adopts the heat sensitive sensor of high sensitivity.
Further, described fire prevention single valve is opening state under normal circumstances, when temperature transducer 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 area is less than 500m
3/ (m
2h).
Technique effect of the present invention is as follows:
The present invention possesses air quantity and frpf double action in conditioning chamber simultaneously, can automatically adjust room temperature and indoor air freshness according to the program of setting, and regulating effect is good; When signal being detected, the present invention by Close All, can effectively close ventilation in 1 minute, reduced spreading of fire, simultaneously outside transmission of electric signals.The present invention adopts brand-new structure, by traditional fire-closing valve, air-conditioner temperature modulating valve Function Integration Mechanism together, has fire prevention and regulates dual functions, greatly reduced valve volume, take up room, reduced cost of production, simultaneously also convenient installation.The present invention adopts the heat sensitive sensor, control panel, motor, helicoidal gear of high sensitivity and with the valve plate of seal ring, compares with traditional fire-closing valve, and higher, the fire prevention actuation time of being quick on the draw is shorter, flameproof effect is better.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In accompanying drawing: 1-air channel, 2-position limit switch, 3-temperature transducer, 4-control panel, 5-motor, 6-screw rod, 7-guide pin bushing, 8-valve plate.
Embodiment
As shown in Figure 1, a kind of fire prevention single valve, comprises motor 5, screw rod 6, guide pin bushing 7, valve plate 8, temperature transducer 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 seal ring with bolt, and seal 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 position limit switches 2 that match with stroke lever.
When not occurring under fire alarm, normal working, can drive screw rod 6 rotations by starting electrical machinery 5, screw rod 6 drives the guide pin bushing 7 left and right straight line motions that become with it spiral to coordinate, and described guide pin bushing 7 drives valve plate 8 side-to-side movements with seal ring that are fixedly mounted on its end, realizes regulation.The air-conditioning modulating valve of fire prevention single valve is connected with air-conditioning coil pipe supply air duct, by regulating valve plate 8 apertures of air-conditioning modulating valve, Air Conditioning flow is changed, thereby realize the adjusting of room temperature.
Motor 5 rear portions are provided with control panel 4, and described control panel 4 is electrically connected to motor 5, position limit switch 2, temperature transducer 3.Temperature transducer 3 is arranged in air channel 1, adopts the heat sensitive sensor of high sensitivity, detects in real time temperature in fire prevention single valve body, and transmission of signal is to control panel 4.Fire prevention single valve is opening state under normal circumstances, when temperature transducer 3 detects while being more than or equal to 70 ° of C high temperature, control panel 4 can send and close valve signal to motor 5, controlling motor 5 moves immediately, valve plate 8 is closed completely in 1 minutes, by 485 ports, to outside, send signal simultaneously.After described valve plate 8 is closed completely, under 500Pa pressure, the inleakage in its valve plate 8 unit areas is less than 500m
3/ (m
2h).
Above embodiment is explanation of the invention, and non-limiting, and more than just part is given an example.Should be noted that, concerning the technician of the industry, simple transformation and the improvement according to basic principle of the present invention and structure, carried out, the combination of carrying out according to above embodiment, includes within protection scope of the present invention.
