Description
Technical field
The utility model relates to a kind of technical field of gas cylinder, especially relate to a kind of be matched on the cylinder neck, can fix and spring sliding pin type safety flack cap device that can quick and convenient mounting or dismounting.It is configured in as on seamless steel gas cylinder such as oxygen, nitrogen, argon gas, carbon dioxide gas and the valve seat or neck ring as steel welded gas cylinders such as acetylene, propylene, propane, liquefied ammonia, fluorine Lyons, avoids external object collision scratch with the protection cylinder valve.
Background technique
Cylinder valve in the gas cylinder is the most easily vulnerable vitals, and the cylinder valve damage can cause its gas leakage even cause accidents such as burning, blast, poisoning.Valve protection cap is one of safety attachment in the gas cylinder, and protection gas cylinder cylinder valve in filling, carry, load and unload, transport, store and using is avoided the collision scratch of external object.
In various countries' gas cylinder safely laws and regulations on the management, when all being arranged, transportation of requirement gas cylinder and loading and unloading gas cylinder must wear the regulation of valve protection cap.When requiring transportation and loading and unloading gas cylinder in China's " gas cylinder safely supervision rules ", must wear the valve protection cap gas cylinder of protective housing (have except) and bump protection ring (except the collection dress gas cylinder), with light packsly gently unload, forbid to throw, slide, roll, bump.
The most valve protection caps that adopt of China are fixed valve protection cap and detachable type valve protection cap two big classes at present, and existing problems are as follows in its structure and the use:
The detachable type valve protection cap as shown in figure 12, it comprises the valve seat 1 that is welded on the bottle 3, valve seat 1 connects valve protection caps 2 by screw thread 4.The screw thread 4 general gas cylinder valve protection cap special screw threads that use are connected with bottleneck with the loading and unloading valve protection cap, because detachable type valve protection cap detachable bottle falling cap when cylinder filling, using gases, so be applicable to multiple cylinder filling anchor clamps and gas cylinder reduction valve, easy to use, therefore use the most extensive.Yet detachable type valve protection cap shortcoming has three: one, because the connecting thread diameter is big, the tooth number is many, and often prohibits oil or high-purity gas gas cylinder and prohibit oil and make this screw thread be in dry condition, and cause corrosion or because of the loading and unloading damage, the valve protection cap screw thread is difficult to rotation because of oxygen; Its two, artificial its amount of labour of rotation loading and unloading major diameter screw thread is big, efficient is low; Its three because the garden male screw degree of depth of detachable type valve protection cap is 1.5 millimeter, be the join strength that guarantees the screw thread place, the valve protection cap wall thickness must be greater than 3 millimeters, the valve protection cap heaviness.
2. fixed valve protection cap as shown in figure 13, it comprises the valve seat 1 that is welded on the bottle 3, valve seat 1 is by bolt 4 fixedly connected valve protection caps 2.The lower end of valve protection cap 2 is provided with about 3 a millimeters at interval ear 21, establish a semicircle inner groove 11 on the valve seat 1 and at ear 21 directions, insert described ear 21 and semicircle interior the ring in the circular hole that forms between 11 with bolt 4 then to be connected described valve protection cap 2 and valve seat 1; Tight a bolt and valve protection cap is fixedly clamped on valve seat after 4.The fixed valve protection cap cylinder valve 5 that can adequately protect can only use specific jig and the gas cylinder reduction valve of filling but shortcoming is the gas cylinder of fixed valve protection cap, gas filling and gas are used bring quite inconvenience, thereby present actual using scope is not extensive.
Reason in sum, most gas cylinders and welded gas cylinder in all parts of the country are not at present all worn valve protection cap in accordance with regulations as majority in modal oxygen cylinder, the nitrogen bottle.Though some gas filling stands under department of the government concerned license granting mechanisms forced draught and is carrying out as possible, but owing to be difficult to obtain cooperating with on one's own initiative of gas user, be difficult to reverse in transportation and the loading and unloading gas cylinder and do not wear the valve protection cap universal phenomenon, this causes the potential safety hazard of the generality that always exists for many years in the gas industry.
