Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.

In the following description, specific details are set forth in order to provide a thorough understanding of the present invention. The utility model can be implemented in a number of ways different from those described herein and similar generalizations can be made by those skilled in the art without departing from the spirit of the utility model. Therefore, the present invention is not limited to the specific embodiments disclosed below.

As shown in fig. 1, the gas drying cylinder according to the present invention includes a desiccant bottle 1, and a solid desiccant 7 is contained in the desiccant bottle 1. The fixed upper cover 2 that is equipped with in top of drier bottle 1, the bottom of drier bottle 1 is fixed with lower cover 8, and in this embodiment, upper cover 2, lower cover 8 all through threaded connection's mode and drier bottle 1 fixed connection, all are equipped with O type circle II 10 between upper cover 2, lower cover 8 and the drier bottle 1 simultaneously, prevent gas leakage through setting up O type circle II. An outer decoration cover 3 is arranged on the outer side of the upper cover 2, the outer decoration cover 3 is fixedly connected with the upper cover 2 through a fastening bolt 4, and meanwhile, an air inlet channel is also arranged between the inner surface of the outer decoration cover 3 and the inner surface of the upper cover 2. The intake duct includes along I11 of vertical direction's intake duct and along II 12 of horizontal direction's intake duct, I11 of intake duct and II 12 intercommunications of intake duct. The middle part of upper cover 2 also is equipped with intake duct III, is equipped with check valve 5 in the intake duct III, and check valve 5 can slide from top to bottom in intake duct III. The cross-section of check valve 5 is T shape, and there is the sealing washer in the outside of check valve, during the whole intake duct III at embedding upper cover 2 centers of check valve, lean on the sealing washer in the extrusion check valve outside, make check valve 5 be connected with upper cover 2, is equipped with the spring between the top of check valve 5 and the bottom of upper cover 2, realizes the automatic re-setting of check valve 5 through the spring. In the initial state, under the action of the elastic force of the spring, the top surface of the one-way valve 5 is tightly attached to the top of the air inlet channel III of the upper cover 2, at the moment, the one-way valve 5 is in a closed state, and air cannot enter the drying agent bottle body. Under the action of external force, the one-way valve 5 is opened downwards, and external air can flow into the desiccant bottle body 1 at the moment, and the solid desiccant dries the air.

The middle part of the lower cover 8 is provided with an air outlet channel, the top end of the air outlet channel is communicated with the desiccant bottle body 1, and the bottom end of the air outlet channel is communicated with the inside of the instrument so as to ensure that the air dried by the solid desiccant directly flows into the instrument. An O-shaped ring I9 is also arranged at the joint of the annular outer surface at the bottom of the lower cover 8 and the instrument to prevent air leakage.

Fine filter cotton 6 is arranged between the bottom surface of the upper cover 2 and the solid desiccant 7 and between the top surface of the lower cover 8 and the solid desiccant 7, and the fine filter cotton 6 can be used for preventing the solid desiccant from blocking an air inlet channel or an air outlet channel.All in oneIn the process, the fine filter cotton 6 is shielded between the upper cover 2 and the solid desiccant, so that the one-way valve can be prevented from falling off.

The working principle of the gas drying cylinder is as follows. As shown in fig. 2, when the instrument is in an inoperative state, outside air need not enter the instrument. At this time, the top surface of the check valve 5 is tightly attached to the top of the air inlet channel III in the upper cover 2, the check valve 5 is in a closed state, and the check valve 5 prevents external air from entering the desiccant bottle 1 and the instrument, so that contact between the external air and the solid desiccant 7 is prevented. When the instrument is in the running state, the pump body in the instrument starts and produces huge suction in the intake duct, makes check valve 5 along the direction downstream that admits air, and check valve 5 opens this moment, and the outside air gets into in drier bottle 1 along intake duct I11, intake duct II 12 and the intake duct III in the upper cover in proper order, dehumidifies the air through solid desiccant, after purifying, flows into in the instrument through the gas outlet channel of lower cover. After the instrument works, the suction force acting on the one-way valve 5 is removed, the one-way valve 5 automatically resets under the action of the spring, and the closed state is recovered again. The structure of the gas drying cylinder ensures that the solid desiccant can dry gas only in the state of instrument operation, and prolongs the service life of the solid desiccant.

The gas dryer cartridge provided by the present invention is described in detail above. The principles and embodiments of the present invention are explained herein using specific examples, which are presented only to assist in understanding the method and its core concepts. It should be noted that, for those skilled in the art, it is possible to make various improvements and modifications to the present invention without departing from the principle of the present invention, and those improvements and modifications also fall within the scope of the claims of the present invention. The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention.
