The structure of the pressure balance valve with built-in louvers in double-layer insulating glass

Abstract

The invention discloses a pressure balance valve structure of a shutter with built-in bilayer hollow glass and belongs to the technical field of sunshade hollow glass products. The shutter comprises a shutter body which comprises inner glass, outer glass, a shutter frame pipe and a sealing rubber strip, the pressure balance valve structure comprises a valve seat, a valve plate and a valve cover, the valve seat is arranged in a shutter frame pipe cavity, the valve seat forms a valve plate containing cavity, an air incoming hole is formed in the cavity bottom wall of the valve plate containing cavity, a group of valve plate shelving flanges are formed on the cavity bottom wall of the valve plate containing cavity, and the valve plate is shelved on the valve plate containing flanges; the valve cover is positioned in the shutter frame pipe cavity, the valve cover forms a valve seat matching cavity, a ventilation pipe extends on one side, facing the sealing rubber strip, of the valve cover, passes by the shutter frame pipe wall on one side, facing the sealing rubber strip, of the shutter frame pipe to tap into the sealing rubber strip and is communicated with the outside, and one side, facing a ventilation pipe hole, of the valve plate contacts with the valve cover cavity wall in an adhered manner. The pressure balance valve structure is high in elusiveness, thereby being capable of avoiding damage caused by artificial contact, convenient to manufacture and mount, ideal in self-adjusting effect, convenient and quick to mount and capable of avoiding damage to glass.

Description

technical field [0001] The invention belongs to the technical field of sunshade hollow glass products, and in particular relates to a pressure balance valve structure of a double-layer hollow glass built-in shutter. Background technique [0002] The double-layer hollow glass built-in blinds mentioned above refer to the construction of a venetian blind that can be raised and lowered as needed in two pieces of glass (inner glass and outer glass) that are arranged in a face-to-face state and that seal the surrounding edges. A window belonging to the category of sunshade hollow glass products. This kind of window has the following self-evident advantages: good heat insulation, so as to reflect the energy saving of the building; excellent sound insulation, so as to avoid the disturbance of external noise; Expected bright effect; through the adjustment of the deflection angle of the venetian blinds, the required indoor lighting requirements can be obtained, privacy can be protect...

Problems solved by technology

However, due to the balloon-like effect of the airbag relative to the airway tube and the connecting tube, it is located outside the double-layer insulating glass, which affects the view on the one hand, and is easy to be damaged by human touch on the other hand, and once damaged, the external moist air will follow the connection Pipes and air ducts enter the double-layer insulating glass, affecting the clarity of the double-layer insulating glass, and even mildew and / or breeding of bacteria in the double-layer insulating glass

Another example is the "insulating glass with adjustable air pressure balance" provided by CN202467536U. Although this patent solution can reflect the technical effect recorded in paragraph 0015 of the specification, it is not difficult to find the following shortcomings by reading paragraphs 0025 to 0030 of the specification: First, the installation is more troublesome because of the need to open installation holes on the glass; second, because the adjustment device is very complicated, it is more troublesome to manufacture and assemble; third, because the adjustment device needs to be operated manually, so Inconvenient to operate, especially, the premise of operating the adjustment device depends on the subjective judgment of whether the air pressure in the interlayer of double-layer insulating glass is balanced with the external atmospheric pressure. However, the basis of human judgment is different from person to person, so it has blindness
