DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution in the embodiments of the utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0021] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention to be protected, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] like Figure 1 As shown, a quick-change valve includes a valve body 1, two quick-change pipes 2 and two screw caps 3; the two quick-change pipes 2 are connected to both sides of the valve body 1; the two screw caps 3 are respectively arranged on the quick-change pipes 2 on both sides; it should be noted that the valve body 1 is a prior art and is not an improvement of this embodiment, and will not be described in detail here.

[0023] like Figure 2 As shown, the quick-connect pipe 2 includes a pipe wall 201, a mounting platform 204, an elastic member, a gasket 206, a sealing ring 207 and an elastic sleeve 203; the mounting platform 204 is annular and arranged around the inner side of the pipe wall 201; one side of the elastic member is arranged around the mounting platform 204; the gasket 206 is annular, and one side thereof is arranged on the side of the elastic member away from the mounting platform 204; the sealing ring 207 is arranged on the side of the gasket 206 away from the elastic member; the elastic sleeve 203 is arranged around the inner side of the pipe wall 201 and extends out of one side opening of the quick-connect pipe 2;

[0024] Specifically, a split pipe opening 208 is further provided at one side opening of the quick-release pipe 2, and the outer side wall of the split pipe opening 208 is inclined; a pipe wall thread 202 is further provided on the outer side of the pipe wall 201, and is located next to the split pipe opening 208;

[0025] More specifically, the elastic member is an O-ring, and its material is polyurethane;

[0026] More specifically, the elastic sleeve 203 is made of polyurethane.

[0027] like Figure 3 As shown, the screw cap 3 is hollow inside and connected at both ends; a screw cap thread 301 is provided at one end of the inner wall of the screw cap 3, and a clamping wall 303 is provided at the other end; the clamping wall 303 is inclined;

[0028] Specifically, the screw cap thread 301 is meshed with the pipe wall thread 202, and the compression wall 303 is in contact with the petaled pipe opening 208, which makes it easier for the petaled pipe opening 208 to press the elastic sleeve 203 inwardly, so that the elastic sleeve 203 fits the outer wall of the pipe more closely.

[0029] The working principle of this embodiment is:

[0030] The utility model is a quick-change valve. First, the screw cap 3 on the quick-connect pipe 2 on one side is loosened, and then one end of the pipe to be installed is inserted along the pipe opening of the quick-connect pipe 2, and the outer wall of the pipe is in contact with the elastic sleeve 203, and the opening of one end is in close contact with the sealing ring 207 on the gasket 206, and continues to be pressed inwardly to deform the O-ring, and then the screw cap 3 is tightened along the pipe wall thread 202, and the compression wall 303 thereof presses the petal pipe opening 208 inwardly, so that the elastic sleeve 203 is more closely fitted to the outer wall of the pipe, so that the pipe and the quick-connect pipe 2 are kept sealed, and then the above operation is repeated to seal the quick-connect pipe 2 on the other side to the pipe, and the installation of the device can be completed.
