Embodiment 1

[0058] Such as Figure 1-Figure 30 As shown, the sealing structure 1 provided by the embodiment of the present invention includes: an elastic sleeve, the elastic sleeve is made of metal material, the elastic sleeve includes a connecting end 112 and an elastic elastic end 111, the connecting end 112 and the elastic end 111 Connected and used for connecting with the valve plate 2 , a cavity is formed inside the elastic end 111 .

[0059] The sealing structure 1 provided by the embodiment of the present invention is applied to the ventilation valve. The sealing structure 1 is installed on the valve plate 2 of the ventilation valve. The connecting end 112 of the sealing structure 1 is connected to the valve plate 2, and the elastic end 111 is facing away from the valve plate 2. direction. In the ventilation valve, the above-mentioned sealing structure 1 is installed on each valve plate 2, such as figure 2 As shown, when the ventilation valve is in the closed state, the adjacent...

Embodiment 2

[0083] Such as Figure 1-Figure 30 As shown, Embodiment 2 of the present invention provides a ventilation valve, including a valve plate 2 and the sealing structure 1 provided in Embodiment 1 above, and the sealing structure 1 is installed on the valve plate 2 .

[0084] Such as figure 1 and figure 2 As shown, the ventilation valve also includes a casing 3, and a ventilation pipeline is arranged inside the casing 3, and a plurality of valve pieces 2 are installed in the ventilation pipeline, and the valve pieces 2 are rotatably connected with the casing 3, and the two sides of the valve pieces 2 are respectively installed There is a sealing structure 1, and the cross-sectional shapes of the two sealing structures 1 installed at both ends of a valve plate 2 may be the same or different.

[0085] When the ventilation valve is in the closed state, the sealing structure 1 on the corresponding side of the adjacent valve slices 2 contacts and squeezes each other to deform, so as ...

Abstract

The invention provides a seal structure and a ventilation valve and relates to the technical field of sealing with an aim to solve the problem about short service life due to a sealing strip of the ventilation valve is greatly affected by the external environment. The seal structure comprises an elastic sleeve which is made from metal materials, the elastic sleeve includes a connecting end and anelastic end with elasticity, the connecting end is connected with the elastic end to be used for being connected with valve blocks, and a cavity is formed in the elastic end. The seal structure is used for sealing between the valve blocks of the ventilation valve, sealing effect is good, and less affected by the external environment, the seal structure is long in service life.

Description

technical field [0001] The invention relates to the technical field of sealing, in particular to a sealing structure and a ventilation valve. Background technique [0002] In the ventilation valve, several valve pieces are installed. When the ventilation valve is in the open state, passages are formed between adjacent valve pieces. When the ventilation valve is switched to the closed state, the valve pieces rotate and the adjacent valve pieces contact, thereby Seal the passage between adjacent valve plates to close the ventilation valve. [0003] In order to avoid gaps between the contact surfaces of adjacent valve plates when the ventilation valve is in a closed state, sealing strips are provided on both sides of the valve plates to enhance the sealing effect between the valve plates. At present, the sealing strips in the prior art are made of silica gel, so when the ventilation valve works in a high-temperature environment, the sealing strip may soften or melt; when the v...
