Problems solved by technology

[0004] However, in actual use, the seal between the blade and the side wall of the box needs to be realized with the help of the baffle on the box. However, if the baffle is set on the side wall of the box, the ventilation area of ​​the box will inevitably be reduced. When the blade is opened , the efficiency of air circulation in the box will be reduced, and the addition of baffles on the inner wall of the box increases the production process, and the production and processing costs are very high

Embodiment Construction

[0036] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0037] A closed valve, refer to figure 2 as well as image 3 , including the box body 1. During installation, the box body 1 is fixedly installed in the wall. In order to facilitate the fixed installation of the box body 1, installation holes 111 are provided at the four corners of the box body 1, and the installation holes 111 are arranged on the installation plate 11. The mounting plate 11 is arranged at right angles, and connects two vertical sides on the box body 1 , and the structural strength of the box body 1 can be improved by setting and installing. An air duct for ventilation is provided in the box body 1, and at least one blade 2 is rotated in the air duct of the box body 1. The blade 2 is used to adjust the ventilation volume in the air duct. The number of blades 2 is preferably two, and two blades are selected. 2. It can not only quickly reali...

Abstract

The invention discloses a sealing valve. According to the technical scheme, the key point is that the sealing valve comprises a box, wherein at least one blade is rotatably arranged in the box; the two sides, close to the box, of the blade are provided with first sealing parts; each first sealing part comprises side sealing strips which can abut against the side walls of the box; the side sealing strips are fixedly arranged on the blade in a blade length direction; when a ventilation opening is in a closed state, the side sealing strips abut against the side walls of the box, so that the sealing between the blade and the side walls of the box can be realized; the sealing strips are arranged to directly abut against the side walls of the box, and a baffle plate is not needed to be arranged in the box, so that the area of the cross section of an air flue is prevented from being affected, and therefore, the ventilation quantity of the box is guaranteed, and the ventilation rate of the box is increased.

Description

technical field [0001] The present invention relates to a ventilator, and more particularly to a hermetic valve. Background technique [0002] At present, in the building ventilation system, an airtight valve needs to be installed in the ventilation duct to adjust the flow of air passing through the duct to realize the sealing and opening of the ventilation duct. However, in actual use, the utility model with the notification number CN2431455Y provides A sealing valve for ventilation and air conditioning can effectively improve the air leakage and airtightness of the sealing strip by setting the sealing rubber strip and the baffle. [0003] Hermetic valves in the prior art, such as figure 1 As shown, it mainly includes a box body (1), and several blades (2) are arranged for rotation in the box body (1), and a retaining strip (13) is provided on the side wall of the box body, and a The sealing rubber strip, when working, the blade rotates, and the sealing rubber strip abuts...
