Simple vacuum device with pressure valve

Abstract

The invention discloses a simple vacuum device with a pressure valve. The simple vacuum device comprises a vacuumizing pipeline, wherein a buffer pipeline is arranged in the vacuumizing pipeline, the buffer pipe is fixed in the vacuumizing pipeline, a main ventilating pipe is arranged at one side surface of the vacuumizing pipeline, one end of the main ventilating pipe is fixed on the vacuumizing pipeline, a pipe joint is arranged at the other end of the main ventilating pipe, the pipe joint is buckled on the main ventilating pipe, a regulating valve is arranged between the pipe joint and the main ventilating pipe, an outer cover is arranged at the other side surface of the vacuumizing pipeline, the outer cover is communicated and connected with the vacuumizing pipeline, the outer cover is of a rectangular structure, a motor is arranged in the outer cover, the motor is fixed in the outer cover by virtue of a support frame, two equilateral side angle steels are arranged in the outer cover, and a water pump is arranged on a place, which is close to the bottom, between the two equilateral side angle steels. The simple vacuum device with the pressure valve is compact in structure, convenient to operate, good in airtightness and large in circulating area, has a certain releasing function, and prevents quick operation from influencing a vacuumizing effect.

Description

technical field [0001] The invention relates to the technical field of vacuum treatment, in particular to a simple vacuum device provided with a pressure valve. Background technique [0002] After the double-layer low-temperature equipment filled with pearlite is installed, the interlayer needs to be vacuumized, and the fine pearlite particles should not escape into the vacuum equipment while vacuuming it. The existing simple vacuum device with a pressure valve is to drill a certain number of small holes on a stainless steel pipe with sufficient diameter, and then wrap the glass fiber cloth on the surface of the steel pipe to form. Although it can meet the basic needs of use, there are still some deficiencies. First, it will take a lot of man-hours to drill holes on the stainless steel pipe, and use this simple vacuum device with a pressure valve to pass through the masonry of the small hole. The limited circulation area leads to low vacuum efficiency, which not only wastes...

Although it can meet the basic needs of use, there are still some deficiencies. First, it will take a lot of man-hours to drill holes on the stainless steel pipe, and use this simple vacuum device with a pressure valve to pass through the masonry of the small hole. The circulation area is limited, resulting in low vacuum efficiency, not only wasting a lot of vacuuming time, but also occupying vacuuming equipment and work stations for a long time
