Description

Technical Field

[0001] The utility model relates to the technical field of end caps, in particular to a novel hose end cap. Background Art

[0002] According to the GJB1123.9-1991 "Hose End Cap" standard, the opening pressure of the hose end cap is 0.6 bar. The width of the winch drum for the longitudinal supply hose of a certain project is only 110 mm, which can only accommodate one row of hoses. Due to limited space, the drum depth is designed to be 530 mm, which can accommodate 150 m of hose with a diameter of 50 mm, and the storage margin is small. The storage capacity of the winch is related to the thickness of the stored material. The storage thickness of the hose is equal to the wall thickness of the hose plus the thickness of the intermediate air layer. Therefore, if the air in the hose is not discharged in time when the hose is collected, it is very likely that the winch reel will not be able to store 150 m of hose smoothly. According to the formula PV = NRT, the opening pressure of the hose end cap is 0.6 bar. The air length of the 150 m hose can only reach 0.6 bar when the air length is 21 m. There is an air risk in the first 129 m of the hose. If you want to continue to discharge the air, you must rely on other power equipment to squeeze the hose, which will undoubtedly increase the cost investment. In order to solve this problem, a new hose end cap is needed. Utility Model Content

[0006] As a further configuration of the utility model, the breathing mechanism includes a connecting tube, which is detachably connected to the air outlet, an outer end of the connecting tube is provided with an air hole, the air hole is connected to the inside of the connecting tube, the outer end of the connecting tube is also provided with a breathable notch, the outer end of the connecting tube is covered with a breathable membrane, and the breathable membrane covers the breathable notch.

[0007] As a further configuration of the utility model, the connecting pipe comprises an inner pipe and an outer pipe which are coaxially arranged, the outer side of the inner pipe and the inner side of the air outlet are provided with matching threads, and the inner pipe is threadedly connected to the air outlet.

[0008] As a further configuration of the utility model, the diameter of the outer tube is larger than that of the inner tube, and a seal is provided between the bottom of the outer tube and the cap body.

[0009] The beneficial effects of the utility model are:

[0010] The utility model provides an air outlet on the side of the end cap body. When the winch is reeled in, even if the air inside the hose cannot reach the opening pressure of the valve of the end cap, the air discharge can be ensured by arranging a breathing mechanism, so that the hose can be reeled in normally. Specifically, the air in the hose is discharged through the air outlet, and then discharged from the air vent after passing through the connecting pipe, and then discharged from the air vent through the air membrane from the air notch. Through the function of the air vent and the air notch, the hose can be exhausted without reaching the opening pressure of the valve of the end cap, so that the hose can be reeled in conveniently.
