With the popularization of large-scale cultivation, people are increasingly stronger to the control consciousness of pouity dwelling place environment, and the ventilation to pouity dwelling place is changed
The requirement of gas also increasingly becomes more meticulous.In large-scale cultivation, roof ventilator efficiently solves the problem of pouity dwelling place ventilation.
Air door plays the important function adjusting whole roof ventilator ventilation size in roof ventilator, when air door is closed, obstructed within doors
Gas, air door carries out ventilation after opening.In addition, air door can also play airtight roof ventilator when not needing ventilation
Effect.
At present, the air door of roof ventilator is all generally to adopt driven type, and driven type air door is disadvantageous in that:
First, expensive；2nd, short life, the service life of tens of thousands of times cannot meet the secondary opening and closing of air door hundreds of thousands and require.
Content of the invention
It is an object of the invention to provide roof ventilator is with self-priming pair of throttle setting, this throttle setting is given up electrically driven (operated)
Traditional approach, structure is simple, reliability is high, and energy reduces cost, increases the service life.
The technical solution adopted for the present invention to solve the technical problems is:
Roof ventilator self-priming pair of throttle setting, the air door in inside the shell rotated including shell and by rotating shaft；Described wind
Door comprises two fans, and two pectinid doors are symmetricly set on inside the shell；Radially it is provided with sealing deep bead in the middle part of shell, sealing deep bead
Article two, middle side edge is respectively equipped with magnetic plate；The shaft parallel of two pectinid doors is in sealing deep bead, and keeps out the wind positioned at sealing respectively
The both sides of plate；The inside edge of two pectinid doors is respectively positioned on the lower section of sealing deep bead, and the inside top surface of two pectinid doors also sets respectively
There is Magnet, Magnet can become magnetic to coordinate with magnetic plate shape.
Further, described sealing deep bead be respectively arranged at two ends with side block aerofoil, side block aerofoil is located at two pectinid doors
Inside front, and sealing cooperation can be formed with the top surface of two pectinid doors.
Further, the inside edge of described two pectinid door bottom surfaces is respectively equipped with counterweight batten.
The invention has the beneficial effects as follows, this pair of throttle setting is fixed on below blower fan, start blower fan when, blower fan case with this
Produce negative pressure in cavity between crust of the device, overcome the magnetic attraction of Magnet and magnetic plate, so that two pectinid doors is turned upwards along rotating shaft
Move and open；When stopping blower fan, two pectinid doors under gravity, fall after rise and close, and absorption is on magnetic plate；Due to magnetic attraction
Effect, air door will not blow hard because of outdoor or other interference factor and automatically open up, its opening and closing is depending on the start and stop of blower fan；Close
Block aerofoil and side block aerofoil both increase the sealing of air door, and counterweight batten can be according to the vacuum magnitude of ventilation and formation
Concrete setting；This apparatus structure is simple, gives up electrically driven (operated) traditional approach, easy for installation, reliability is high, and can reduce into
This, increase the service life.

Specific embodiment
In conjunction with shown in Fig. 1～3, the present invention provides roof ventilator self-priming pair of throttle setting, including shell 1 and pass through
The air door that rotating shaft rotates in inside the shell；Described air door comprises two fans, i.e. the first air door 2a and the second air door 2b, and two pectinid doors are in half
Circle, is symmetricly set in shell 1；Radially it is provided with sealing deep bead 3, in two sides of sealing deep bead 3 in the middle part of shell 1
Portion is respectively equipped with magnetic plate, i.e. the first magnetic plate 4a and the second magnetic plate 4b；The shaft parallel of two pectinid doors is in sealing deep bead
3, i.e. first rotating shaft 21a and the second rotating shaft 21b, and it is located at the both sides of sealing deep bead 3 respectively；Two rotating shafts can be passed through to turn respectively
Axle bed is fixed, i.e. first rotating shaft seat 22a and the second shaft seat 22b；Interfere to prevent two pectinid doors from producing when rotating, can
With certain gap reserved between the inner side straight flange of two pectinid doors；In conjunction with shown in Fig. 4, the inner side straight flange of two pectinid doors is respectively positioned on
The lower section of sealing deep bead 3, the width of sealing deep bead 3 should be greater than the gap of two pectinid doors；The inside top surface of two pectinid doors is also
