Description

Technical Field

[0001] The utility model relates to the technical field of mixed gas filling, in particular to a gas mixing filling device. Background Art

[0002] In industrial manufacturing, mixed gas has a wide range of uses. Unlike high-purity gas, mixed gas is not a single gas, but a combination of two or more gas components. It is a diversified product specially designed for special purposes and specific industries. The preparation of mixed gas is generally based on customer needs. It can be continuously mixed with a single gas on site, or it can be mixed in proportion in advance and then filled into cylinders of different specifications for customer use. There are many options.

[0003] However, the existing gas mixing and filling device does not install equipment to detect gas leakage around the bottle valve during the inflation process. If gas leaks from the connection between the bottle valve and the inflation pipe during inflation, the staff cannot detect it at the first time and thus cannot make timely and correct emergency treatment. Therefore, a gas mixing and filling device is proposed. Utility Model Content

[0006] A gas mixing and filling device comprises a bottle body and a filling tube, wherein a bottle valve is arranged at the output end of the bottle body, an interface is arranged at the output end of the filling tube, a detachable connection is realized between the bottle valve and the interface, an annular sealing seat is sleeved on the bottle body, an internal hollow truncated cone-shaped sealing cover is arranged above the bottle body, the bottom of the sealing cover is hollowed out, the filling tube runs through the top of the sealing cover, a sealing ring is fixedly installed at the bottom of the sealing cover, an annular groove is opened at the top of the sealing seat, the sealing ring is movably installed inside the annular groove, and a gas detection alarm is fixedly installed on the inner side wall of the sealing cover.

[0007] Furthermore, a clamping groove is provided on the inner bottom surface of the annular groove, a clamping block is fixedly installed on the bottom surface of the sealing ring, and the clamping block is movably installed inside the clamping groove.

[0008] Furthermore, an external thread sleeve is fixedly mounted on the side wall of the cover, a first external thread is formed on the outer wall of the sealing seat, and an internal thread sleeve is threadedly connected to the sealing seat via the first external thread.

[0009] Furthermore, a second external thread is formed on the side wall of the bottle body, an internal thread is formed on the inner wall of the sealing seat, and the sealing seat is threadably connected to the outside of the bottle body via the second external thread and the internal thread.

[0010] Furthermore, a limiting ring is fixedly mounted on the bottle body, and the top surface of the limiting ring is tightly fitted with the bottom surface of the sealing seat.

[0011] Furthermore, sealing rings are fixedly installed on the two inner arc surfaces of the annular groove, and the sealing rings are made of elastic rubber material.

[0012] The beneficial effects of the utility model are as follows:

[0013] 1. When the utility model is inflated, the staff first connects the interface with the bottle valve, and then installs the sealing ring to the inside of the annular groove. If there is gas leakage during the inflation process, the leaked gas will flow inside the sealing cover. Since the gas detection alarm is fixedly installed on the inner side wall of the sealing cover, if the gas detection alarm detects that there is a change in the gas content and there is a risk of leakage, the alarm program can be immediately activated, thereby reminding the staff to take corresponding emergency measures immediately.
