Detailed Description

The invention is further described with reference to the accompanying drawings.

As shown in fig. 1 to 5, a bonnet with a protective outer sleeve comprises a protective sleeve 1, a ring groove 101, an introduction groove 102, a blind mounting hole 103, a protective sleeve base 2, a clamping protrusion 201, an internal threaded hole 202, a bonnet body 3, an external threaded connector 301 and an internal threaded mounting hole 302.

Take valve cap of protective sheath, including valve cap body 3, set up at the protective sheath base 2 and the cover at 3 tops of valve cap body and establish protective sheath 1 in the 3 outsides of valve cap body, be equipped with internal thread mounting hole 302 in the middle of 3 valve cap bodies, the outer wall of protective sheath base 2 is equipped with a joint arch 201 at least, has seted up installation blind hole 103 in the middle of the protective sheath 1, sets up a leading-in groove 102 at least along installation blind hole 103 axial on the installation blind hole 103 inner wall, be equipped with annular 101 that sets up along installation blind hole 103 circumferencial direction at the end that lies in leading-in groove 102 on installation blind hole 103 inner wall, leading-in groove 102 one end is linked together with annular 101.

In this embodiment, two clamping protrusions 201 are disposed on the outer wall of the protective sheath base 2, the two clamping protrusions 201 are located at the outer wall opposite positions of the protective sheath base 2, two lead-in grooves 102 are disposed on the inner wall of the installation blind hole 103, and the two lead-in grooves 102 are located at the inner wall opposite positions of the installation blind hole 103 and correspond to the clamping protrusions 201.
