Abstract
The present invention relates to a kind of ventilating fire prevention equipment, more particularly to a kind of fire prevention single valve, it is made of motor, screw rod, guide sleeve, valve plate, temperature sensor, screw rod is housed on the motor output shaft, the screw rod is mounted on inside guide sleeve, it is connect with guide sleeve at spiral movable, the end of the guide sleeve is equipped with the valve plate with sealing ring.The present invention has ventilating fire prevention, air-conditioning air volume regulatory function, full-featured, small in size, intelligence degree is high.
Description
Technical field
The present invention relates to a kind of fire equipments, and in particular to a kind of ventilating fire prevention valve.
Background technique
In pipeline for giving wind for air conditioner, in order to prevent fires, it is usually mounted with fire resisting damper.Although traditional fire resisting damper can have fire prevention
Effect, but air-conditioning cannot be adjusted according to indoor environment demand, need the adjusting of additionally mounted fresh air and air-conditioning
Valve, installation volume increases after the two superposition, and occupied space is excessive, and manufacturing cost rises, and is also not easy to install.
For this purpose, we have researched and developed a kind of Novel fireproof single valve, it is mounted in air-supply or exhaust duct, spirit can be played
Quick effective ventilating fire prevention effect, while air-conditioning can be adjusted again.When indoor generation fire, by fire prevention single valve
When air themperature reaches 70 °C, fire prevention single valve will start bolt down procedure, and entire valve process of closing is no more than 1 minute.It is single by fire prevention
Valve adjusts the control, it can be achieved that room air freshness and temperature to air-conditioning amount；When indoor generation fire, can have
The closing of effect is divulged information, and the sprawling of fire, while outside transmission telecommunications number are reduced.
Summary of the invention
The purpose of the invention is to overcome the deficiencies of the prior art and provide a kind of more compact structure, reaction faster, had both had
There is fire-proof function, be adjustable again and be vented in integrated fire prevention single valve.
The present invention is achieved by the following technical programs:
A kind of fire prevention single valve, it is characterised in that: including motor, screw rod, guide sleeve, valve plate, temperature sensor, control panel, institute
It states equipped with screw rod on motor output shaft, the screw rod is mounted on inside guide sleeve, connect with guide sleeve at spiral movable, the guide sleeve
End is equipped with the valve plate with sealing ring.
Further, the guide sleeve is equipped with stroke lever, and the guide sleeve top is set opens there are two the stroke with stroke lever matching
It closes, the motor rear portion is equipped with control panel, and the control panel is electrically connected with motor, travel switch, temperature sensor.
Further, the temperature sensor is mounted in air duct, using the heat-sensitive sensor of high sensitivity.
Further, the fire prevention single valve is in open state under normal circumstances, when temperature sensor detects 70 °C of height
Wen Shi, valve plate can completely close in 1 minutes, while export feedback signal outward, after the valve plate completely closes,
Under 500Pa pressure, the inleakage on valve plate unit area is less than 500m3/(m2·h)。
Technical effect of the invention is as follows:
The present invention is provided simultaneously with air quantity and fireproof double action in regulation room, can adjust automatically room according to the set procedure
Interior temperature and room air freshness, regulating effect are good；When detecting fire alarm, the present invention is in 1 minute by whole passes
It closes, ventilation can be effectively turned off, reduce the sprawling of fire, while outside transmission telecommunications number.The present invention uses completely new structure, will
Traditional fire resisting damper, air-conditioner temperature regulating valve function combine, and have and prevent fires and adjust dual function, greatly reduce valve
Volume, occupied space reduce production cost, while also facilitating installation.The present invention uses the heat-sensitive sensor of high sensitivity, control
Making sheet, motor, helicoidal gear and the valve plate with sealing ring, compared with traditional fire resisting damper, be quick on the draw higher, fire prevention movement
Time is shorter, flameproof effect is more preferable.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention.
In attached drawing: 1-air duct, 2-travel switches, 3-temperature sensors, 4-control panels, 5-motors, 6-screw rods,
7-guide sleeves, 8-valve plates.
Specific embodiment
As shown in Figure 1, a kind of fire prevention single valve, including motor 5, screw rod 6, guide sleeve 7, valve plate 8, temperature sensor 3, control panel
4.Motor 5 is fixedly mounted in pipeline, screw rod 6 is housed, the screw rod 6 is mounted on inside guide sleeve 7, and and guide sleeve on output shaft
7 connect at screw pair, and the end of guide sleeve 7 is fixedly installed with the valve plate 8 with sealing ring with bolt, and sealing ring and valve plate 8 are all made of
Fire proofing material production.Stroke lever is installed on guide sleeve 7, set above guide sleeve 7 there are two with stroke lever match travel switch 2.
When not occurring under fire alarm, normal operating conditions, motor 5 can be started, screw rod 6 is driven to rotate, screw rod 6 drive therewith at
The guide sleeve 7 or so of threaded engagement moves along a straight line, and the guide sleeve 7 drives the valve plate 8 with sealing ring for being fixedly mounted on its end left
Aperture regulation is realized in right movement.The air-conditioning regulating valve of fire prevention single valve is connected with air-conditioning coil pipe air supply duct, by adjusting air-conditioning
8 aperture of valve plate of regulating valve, makes Air Conditioning flow change, to realize the adjusting of room temperature.
5 rear portion of motor is equipped with control panel 4, and the control panel 4 is electrically connected with motor 5, travel switch 2, temperature sensor 3
It connects.Temperature sensor 3 is mounted in air duct 1, warm in real-time detection fire prevention single valve body using the heat-sensitive sensor of high sensitivity
Degree, transmitting signal to control panel 4.Prevent fires single valve it is in open state under normal circumstances, when temperature sensor 3 detect be greater than or
When equal to 70 °C of high temperature, control panel 4 can send to motor 5 and close valve signal, and control motor 5 acts immediately, make valve plate 8 at 1 minute
It is completely closed in time, while sending fire alarm to outside by 485 ports.After the valve plate 8 completely closes, in 500Pa
Under pressure, the inleakage on 8 unit area of valve plate is less than 500m3/(m2·h)。
Above embodiments are explanation of the invention, and non-limiting, the above only some examples.It should be noted that right
For the technical staff of the industry, the simple transformation and improvement that basic principle and structure according to the present invention carry out, according to above
The combination that embodiment carries out, is included within protection scope of the present invention.
