Detailed Description
A fresh air valve structure comprises a valve body 1, blades 2, an actuating mechanism 3 and a transmission structure 4, wherein the blades 2 and the transmission structure 4 are arranged on the valve body 1, and the blades 2 are connected through the transmission structure 4; the method is characterized in that: the wind shield is characterized in that the valve body 1 is provided with wind shields 5 and a transverse middle partition 6, the transverse middle partition 6 is arranged between the blades 2, the wind shields 5 are arranged on two sides of the transverse middle partition 6, and the wind shields 5 are also arranged at the upper end and the lower end of the valve body 1; the blade 2 is of an oval structure as a whole, and trapezoidal grooves 2-1 are formed in two ends of the blade; the sealing structures 7 are arranged at two ends of the blade 2, each sealing structure 7 comprises a circular hollow structure 7-1 and a trapezoidal fixing structure 7-2, the sealing structures 7 are arranged at two ends of the blade 2 through the trapezoidal fixing structures 7-2 and the trapezoidal grooves 2-1 in a matched mode, and the blades 2 are sealed through the circular hollow structures 7-1 in a matched mode; the transmission structure 4 comprises a transmission rod 4-1, a transmission piece 4-2 and a driven shaft 4-3, wherein the driven shaft 4-3 is fixed in the blade 2 and is connected with the transmission rod 4-1 through the transmission piece 4-2.
5-6 the blade be one set of, be provided with horizontal mesophragma 6 between every group blade 2, seal structure 7 and deep bead 5 cooperation. The wind deflector 5 is in an L-shaped structure. The blade 2 is hollow, and two ends of the blade are sealed by oil-containing nylon. The sealing structure 7 is manufactured by integrally molding low-temperature resistant silica gel.
In the specific implementation: the installation of the sealing strip is facilitated through the trapezoidal groove structure, and the installation is convenient; the sealing strip is made of low-temperature-resistant silica gel, is not easy to deform and has a good sealing effect; the low-temperature-resistant silica gel is bonded by the polyurethane foaming sealant and the Teflon, so that the adhesive property is good, and the flame-retardant effect is excellent; the low-temperature resistant silica gel has the characteristics of high resilience, low elastic loss rate, excellent elongation at break, excellent aging resistance and the like; the annular sealing parts are mutually extruded and compressed after the blades are closed, and the sealing effect is effectively improved compared with the existing fillet sealing. The upper blade and the lower blade are fixed on the rotating shaft through the blade rotation stopping structure, so that the influence on the reliability of a product caused by the rotation of the blades due to self weight is avoided; the upper blade and the lower blade which are matched in the arc shape can avoid the phenomenon that the temperature difference between the left side and the right side of the blade is too large, so that condensed water is caused, and the cold bridge phenomenon is effectively solved.
