Gas pressurizing equipment

The utility model discloses a gas pressurizing device which comprises a tank body, a support is fixedly connected to the tank body, a partition plate is slidably connected to the interior of the tank body in a limited mode and divides the interior of the tank body into a pressurizing cavity and a pressure applying cavity, and an elastic assembly is arranged in the pressure applying cavity and connected with the partition plate. The side wall of the tank body is provided with an air outlet in the sliding range of the partition plate, the air outlet is connected with an air outlet pipe through a first valve, the pressurizing cavity is connected with an air inlet pipe, the air inlet pipe is provided with a second valve, and the side wall of the tank body is provided with a pressure gauge in the pressurizing cavity; the partition plate is elastically supported through the elastic assembly, and when low-pressure gas reaches medium pressure, the partition plate overcomes resistance of the elastic assembly to slide,
