Pressure adjustable type hollow glass door window

Abstract

The invention relates to a pressure adjustable type hollow glass door window. The pressure adjustable type hollow glass door window comprises an external glass layer, a middle glass layer, an internalglass layer, a first frame plate and a second frame plate, and the external glass layer, the middle glass layer and the first frame plate enclose a first hollow cavity; a shutter blind and a pull rope are arranged in the first hollow cavity; the internal glass layer, the middle glass layer and the second frame plate enclose a second hollow cavity; the pressure adjustable type hollow glass door window further comprises a first balance pipe and a second balance pipe, one end of the first balance pipe communicates with the first hollow cavity, and the other end of the first balance pipe communicates with the atmosphere; and one end of the second balance pipe communicates with the second hollow cavity, and the other end of the second balance pipe communicates with the atmosphere. By mountingthe balance pipes at the positions of the first hollow cavity and the second hollow cavity, the air pressure in the hollow cavities of the hollow glass door window is adjusted, so that dynamic equilibrium is achieved between the air pressure in the hollow cavities and the outside world, and the problems that the glass bends outwards, the glass visually deforms, and the glass is exploded to be broken are prevented from occurring.

Description

technical field [0001] The invention relates to the technical field of doors and windows, in particular to a pressure-adjustable hollow glass door and window. Background technique [0002] Insulating glass is a high-efficiency sound-insulating and heat-insulating glass made of two pieces of glass, using a high-strength and high-air-tight composite adhesive to bond the glass piece to the aluminum alloy frame plate; it is a kind of good heat insulation and sound insulation. , anti-condensation, and can reduce the weight of building building materials, praised by the majority of users, the products are widely used in hotels, restaurants, office buildings and households and other places. [0003] When the production place and the installation place of insulating glass doors and windows are at the same or similar latitude, under the same conditions, the pressure inside the hollow cavity of insulating glass doors and windows is always the same as the external pressure. However, w...

Problems solved by technology

However, when the latitude difference between the production place of the insulating glass doors and windows and the installation place is large, due to the large pressure difference between the inside and outside of the insulating glass doors and windows, the two pieces of glass will deflect outward, the glass will be visually deformed, and even the glass will burst. a series of questions
