Specific embodiment
The structural principle of the utility model and working principle are described in detail with reference to the accompanying drawing:
As shown in Figs 1-4, a kind of air port regulating valve of the utility model, including frame 1,1 center of frame are equipped with circular ventilation
Mouthfuls 2,2 center of ventilation opening is equipped with the support 3 with internal thread hole 31, and support 3 is connect by strut 4 with frame 1, internal thread hole 31 and
Ventilation opening 2 is coaxial, and internal thread hole 31 connect screw rod 5, and one end that screw rod 5 stretches to 2 inside of ventilation opening is equipped with cyclic annular card slot (in figure not
Draw), snap ring 6 is embedded in the card slot, strut 4 has been respectively articulated with symmetrically arranged semicircle valve plate 7, two semicircle valve plates
7 centers are equipped with groove 71 corresponding with support 3, and two lateral edge semicircle valve plates, 7 rotation direction of support 3 is equipped with and groove 71
The cambered surface 32 of fitting is hinged with symmetrically arranged connecting rod 8, the spiral shell opposite with card slot between snap ring 6 and semicircle valve plate 7 respectively
5 one end of bar is installed with the rotating part 9 for rotating screw rod, and the rotating part 9 in the present embodiment selects butterfly spanner.
The diameter of semicircle valve plate 7 is identical as the diameter of ventilation opening 2, to guarantee when two semicircle valve plates 7 are closed
Entire ventilation opening 2 can be covered.
The outer rim of two halves circular valve plate 7 is installed with sealing element (being not drawn into figure), improves regulating valve in the present embodiment
Leakproofness, the sealing element that section is " C " shape is embedded on the circumference of two semicircle valve plates, makes two semicircle valve plates
7 after deployment, and the sealing element on semicircle 7 circumference of valve plate can be fitted closely with ventilation opening 2, guarantees the sealing performance of regulating valve.
In order to improve stability, prevent the screw rod 5 when ventilation from rotating, on the screw rod 5 between support 3 and rotating part 9
Locking nut can also be set.
The working principle of the utility model is as follows:
As shown in Fig. 2, rotating screw rod 5, and then convert screw rod for the rotation displacement of screw rod 5 by rotation rotating part 9
5 straight-line displacement makes the distance between snap ring 6 and support 3 become larger or become smaller, the snap ring 6 of 5 one end of screw rod with screw rod 5 rotation
Axial direction along ventilation opening is displaced, and drives two semicircle valves by snap ring 6 and two hinged connecting rods 8 of semicircle valve plate 7
Plate 7 moves, and two semicircle valve plates 7 are unfolded or are folded using its articulated shaft as axis, so formation to the opening of ventilation opening 2 or
It closes.
When snap ring 6 is mobile to 2 direction of ventilation opening, final plant closure ventilation opening 2 is slowly unfolded in two halves circular valve plate 7；Work as card
When ring 6 is far from ventilation opening 2, the semicircle folding of valve plate 7 is bigger, i.e., ventilation opening 2 is opened bigger.
This specific embodiment is only the explanation to the utility model, is not limitations of the present invention, ability
Field technique personnel can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but
As long as all by the protection of Patent Law in the scope of the claims of the utility model.
