Abstract
The invention relates to the technical field of welding container steel cylinders, in particular to a gas cylinder valve safety cap for a welding container steel cylinder. The gas cylinder valve safety cap comprises a valve safety cap body, a bolt hole is formed in the outer edge of an annular sleeve on the lower portion of the valve safety cap body, a convex rib belt is arranged on the inner side of the annular sleeve of the valve safety cap body, and an arc-shaped opening is formed in a cap shell of the valve safety cap body. The gas cylinder valve safety cap has the beneficial effects of being novel in structure, simple in design, firm in connection with the welding steel cylinder, not likely to disengage and very high in practical value.
Description
Technical field
The present invention relates to welded vessel steel cylinder technical field, specifically a kind of welded vessel steel cylinder gas cylinder valve safety
Cap.
Background technology
There is welding steel cylinder to be characterized as that with a circle groove external diameter be the bottleneck of 79.5mm at present on the market, coordinate installation with which
Bottom vertically for 80mm internal diameter safety helmet.Mounting means is the bottleneck for safety helmet being placed on welded gas cylinder, then passes through
Bolt bolt is fastened, and the vertical internal diameter of this safety helmet is not firm enough with the cooperation of the reeded bottleneck of welded gas cylinder band, safety
Cap has the risk for coming off.
Content of the invention
For the problems referred to above, the present invention provides a kind of structure novelty, with welding steel cylinder be connected firmly, safety difficult for drop-off
Cap.
For achieving the above object, the present invention is adopted the following technical scheme that.
A kind of welded vessel steel cylinder gas cylinder valve safety helmet, including valve safety helmet body, the valve safety helmet sheet
The lower section ring set external margin of body is provided with bolt hole, is provided with convex tendon band, in the cap shell of the valve safety helmet body on the inside of which
It is provided with arc opening.
Further, the convex tendon band can be a ring type convex tendon band, or segmentation convex tendon band.
Further, the bolt holder is inner groovy and carries through hole, centre is tightly open with bolt.
Further, the valve safety helmet body bottom portion is provided with the bolt holder with through hole of external groove.
The invention has the beneficial effects as follows：Structure novelty, design is simple, with welding steel cylinder be connected firmly, difficult for drop-off, have
Very strong practical value.

Specific embodiment
Below in conjunction with the accompanying drawings and embodiment the present invention is described in detail.
As shown in Fig. 1,2,3 and 4, a kind of welded vessel steel cylinder gas cylinder valve safety helmet, including valve safety helmet body,
The lower section ring set external margin of the valve safety helmet body is provided with bolt hole 1, is provided with convex tendon band 2, the valve on the inside of which
The cap shell of safety helmet body is provided with arc opening 3, during installation, lower section ring set is put on welding steel cylinder, snaps into convex tendon band 2
In groove 4 on steel cylinder, then bolt 5 is passed through bolt hole 1 and groove 4 and be tightened.This structure and welding steel cylinder
Very firmly and it is difficult to come off after connection, meanwhile, by arc opening 3 is provided with, facilitate the peace installation and dismantling of the equipment such as decompressor table
Unload.
Further, the convex tendon band is a ring type convex tendon band.
Further, as shown in figure 5, the convex tendon band can also be segmentation convex tendon band, around segmentation convex tendon band 6 and bottleneck
Groove when bolt bolt is tight more constant reliability.
Further, as shown in Fig. 2 at the safety helmet fastening for inner groovy the bolt holder with through hole, middle
Tightly it is open with bolt, after installing fastening, screw is stuck in the arc groove of gas cylinder neck, is so easy to carriage bolt tight.
Further, as shown in figure 3, the bolt with through hole at the valve safety helmet bolt fastening for external groove is propped up
Frame, centre is tightly open with bolt, and after installing fastening, screw is sunken in groove, is difficult to loosen.
Finally it should be noted that：Above example only not limits technology described in the invention in order to the present invention to be described
Scheme；Therefore, although this specification with reference to each above-mentioned embodiment to present invention has been detailed description, but, this
Field it is to be appreciated by one skilled in the art that still can modify to the present invention or equivalent；And all are without departing from this
The technical scheme of the spirit and scope of invention and its improvement, which all should be covered in scope of the presently claimed invention.
