Safety valve cap and safety valve

A safety valve cap for adjusting, closing and opening valves, the safety valve cap comprising:

• an inner sleeve and an outer sleeve, which are arranged concentrically one inside the other and coupled to each other by a retaining device, with respective axial upper ends and lower ends,
• wherein the two sleeves are axially movably arranged relative to each other in a defined lifting height, and can be brought from a pulled position into a pressed position by pressing or pulling the outer sleeve toward the inner sleeve and vice versa,
• wherein the inner sleeve envelops a valve chamber, which is covered at the upper end by a lid, whose interior side has centrally arranged on it a point support for supporting a valve, as well as a female thread at the lower end of the inner sleeve to be screwed onto a valve, so that a valve screwed into the female thread can be closed with the inner sleeve completely screwed on, and wherein the outer sleeve has a handle for adjusting, closing and opening a valve during use, and also a cover at an upper end, and wherein both sleeves have an interlocking tooth system with teeth and recesses, which are arranged axially limited in such a way as to only interlock in the pressed position, so that in the pressed position, the sleeves are rotationally coupled, and turning the handle on the outer sleeve causes the inner sleeve to also turn, and an inserted valve is adjusted, and wherein, in the pulled position, the outer sleeve is decoupled from the inner sleeve, and can be freely rotated without turning the inner sleeve, so that the valve setting can only be changed with the handle in the pressed position during use,
• wherein the outer sleeve protrudes over the upper end of the inner sleeve in the pulled position at least in the lifting height, and has a through or half-side radial borehole axially right above the upper end of the inner sleeve, through or into which a lock bolt or bracket can be passed in order to secure the valve setting, which when located over the inner sleeve mechanically prevents the sleeves from being pressed toward each other, so that turning the handle only results in a free rotation of the outer sleeve, and no valve adjustment can take place.
