Abstract
The utility model relates to a vacuum high-pressure insulation valve, which is applied to sealed containers which need vacuuming and filling with high pressure air and used for overcoming the defect that a traditional vacuum valve and a traditional high pressure valve cannot achieve effective insulation between high pressure environment and vacuum environment. The vacuum high-pressure insulation valve comprises a main valve body, a bellow assembly, a valve core and a valve plate, wherein an inner cavity of the main valve body is divided into two parts by a partition plate with through holes for air flow to pass through, and the valve plate driven by the valve core to seal the partition plate is arranged in a cavity on the side of a high pressure port. Thus, the vacuum high-pressure insulation valve can not only meet requirements of vacuuming of the sealed containers, simultaneously achieve the technical effect that the higher the pressure of the high pressure port is, the better of sealing of the valve plate is. In addition, the vacuum high-pressure insulation valve has the advantages of being simple in structure, convenient in taking materials and low in cost.
