Abstract
The utility model relates to a separate safety protecting cylinder cap, composed of a cap and a cap base fixedly connected with the cap. The inner ring of the cap base is provided with screw thread connected with a gas cylinder, the cap is composed of a separate cap which can be separately disassembled, and the cap is hinged with the cap base. The utility model has the advantages of simple structure, and convenient operation and use. The cylinder cap need not be disassembled in cylinder inflation and vent, or valve replacement, which reduces trouble, the phenomenon of cylinder cap loss can not be happened, and therefore, the utility model further improves cylinder security in using.
Description
The utility model relates to a kind of protective gear of gas cylinder upper air valve, but the particularly a kind of gas cylinder safety protection valve protection cap upper end and distinguish that is fixed on.
At present, general safety protection valve protection cap on steel gas cylinder has two classes in the prior art: a class is a free-standing, this valve protection cap is to be connected with steel cylinder with screw thread, need during use valve protection cap is unloaded, could be pneumatic inflation, venting or transposing valve, and must again the valve protection cap rotation be set up thereafter, use cumbersome, therefore not welcome by the user, so most gas cylinders of field operation all become not have the valve protection cap state, and valve is exposed, and are easily broken, cause gas to leak outside, major accidents such as serious meeting is poisoned, fire, blast; Another kind of is fixed valve protection cap, this structure is the improvement of relative free-standing valve protection cap structure, promptly when gas cylinder inflation, venting, can not unload valve protection cap, but when the transposing valve, must unload valve protection cap, this kind structure in use still is inconvenience, and the handwheel of valve also is exposed, and very easily crashes and hit curved valve stalk like this when operation, causes gas leakage.
The purpose of this utility model is to overcome existing defective in the prior art, but the safety protection valve protection cap of the distinguish that need not to unload when a kind of operation is provided.
To achieve these goals; time routine scheme that adopted of the present utility model: the cap seat that split safety protection valve protection cap comprises cap and fixedlys connected with cap; the inner ring of this cap seat is equipped with the screw thread that can be connected with gas cylinder; but the earlap that its cap is opened by distinguish is constituted, and this earlap and cap seat are hinged.
The utility model is simple in structure, uses easy to operately, needn't unload valve protection cap again when gas cylinder inflation, venting or transposing valve, has reduced trouble, no longer take place valve protection cap in use lose phenomenon, thereby improve gas cylinder safety reliability in use further.
The utility model will be further described below in conjunction with accompanying drawing and embodiment.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the sectional drawing of the utility model earlap upper end lock body structure.
With reference to shown in Figure 1, the cap seat 2 that the utility model comprises a cap and fixedlys connected with cap, the inner ring of this cap seat 2 are equipped with the screw thread 7 that can be connected with gas cylinder.But the earlap that cap is opened by distinguish is constituted, and described earlap has two lobes at least, is equipped with two lobe earlaps in the present embodiment, i.e. earlap 1.1 and 1.2.The lower end of this two lobes earlap 1.1,1.2 all is equipped with the through hole (failing among the figure to show) that is rolled into by its edge, and be connected with the hangers 3 that protrudes on cap seat 2 two edges respectively, screw rod 4 passes through behind hangers and the through hole fastening with nut 6, this earlap 1.1,1.2 promptly and cap seat 2 be the relatively turnable state that is hinged.Like this, separating, closing up of earlap 1.1,1.2 is all convenient, flexible, even damage to some extent, also is easy to transposing, overhauls.
With reference to Fig. 1, shown in Figure 2, the upper end of earlap 1.1 is equipped with a lock body 5, is equipped with a snapper bayonet lock 5.2 that acted on by spring 5.1 on this lock body 5, and another earlap 1.2 upper ends are equipped with the dead bolt 8 of a band opening 8.1.During use, only need press snapper bayonet lock 5.2, earlap 1.2 closes, thin portion on the snapper bayonet lock 5.2 is entered on the dead bolt 8 open 8.1, unclamp snapper bayonet lock 5.2 then, moving on the snapper bayonet lock 5.2 under spring 5.1 effects, the thick portion on this snapper bayonet lock 5.2 enters dead bolt 8 upper sheds 8.1, so, earlap 1.1,1.2 is promptly fastened and is fixedly connected and no longer separated.Open earlap 1.1,1.2 as need, also only need press snapper bayonet lock 5.2, dead bolt 8 upper sheds 8.1 break away from from snapper bayonet lock 5.2 thin portions, and two earlaps 1.1,1.2 also promptly separate.
In addition, the utility model also is equipped with a radial groove 9 on the cap seat, so just applicable to the gas cylinder of various different connection form and size, enlarged Applicable scope.
Earlap 1.1,1.2 described in the utility model has adopted the manufacturing of 3mm Plate Steel, therefore when the carrying gas cylinder, only needs earlap 1.1,1.2 is closed up, and just can guarantee the safety protection to cylinder valve.
