Description
Technical field
The utility model patent relates to a kind of emergency treatment device for steel cylinder, refers in particular to a kind of leakage-baffling device for cylinder valve.
Background technique
Steel cylinder is a kind of container for the splendid attire liquid pressurized gas, and the gas of splendid attire comprises the classifications such as inflammable, combustion-supporting, severe toxicity, non-flammable compressive gas, and except non-flammable compressive gas, other three class has a strict requirement for leakage-preventing.Such as the gas leakage event of liquefied gas cylinder valve, although be small probability event, because liquid gas itself belongs to inflammable and explosive dangerous goods, have just in case causing danger property and harmfulness are larger, so that the emergency processing of Liquified gas leakage just seems is particularly important.
What the Europe cylinder for liquefied gas adopted is straight valve design, when leaking air, can only use high-voltage regulator to carry out leak stopping, and cost is expensive, and must be operated by the professional and technical personnel.And the most employing of the liquefied gas cylinder valve of China is the angle valve design, exist simultaneously valve and body joint and the ring wear of valve own etc. and reveal hidden danger, if reveal in tooth line and the valve, leak stopping is also relatively more difficult, adopted traditional approach that wet cotton-wadded quilt seals lid both heavy difficult operation and plugging effect were also very undesirable in the past, so, need in a hurry a kind of leakage-baffling device that operation is simple, can realize that the steel cylinder of revealing occurs in fast effective shutoff, then is transferred to safe area with steel cylinder.
Summary of the invention
The purpose of this utility model provides a kind of leakage-baffling device for cylinder valve, and the cylinder valve of leakage occurs in effective shutoff fast, and operation is simple.
The utility model is realized with following technological scheme: a kind of leakage-baffling device for cylinder valve, wherein, comprise be used to the steel bowl cover body that covers whole valve and be used for the fixedly push rod component of steel bowl cover body, the cup of described steel bowl cover body is along being inlaid with seal ring, the middle part, the cup end of steel bowl cover body is provided with screw, described push rod component comprises the threaded mandrel that promotes cross bar and vertically be located in lifting cross bar middle part with screw thread, the top of described threaded mandrel is provided with operating stem, the bottom of threaded mandrel and the corresponding setting of screw on the steel bowl cover body, the two ends of described lifting cross bar are provided be used to the hook on the guard ring handle that is articulated in steel cylinder.
Further, the threaded connection place of described threaded mandrel and described screw is provided with screw shell, if behind the thread abrasion, only needs to change screw shell just passable.
Adopt technique scheme, the beneficial effects of the utility model are:
The leakage-baffling device that the utility model is realized is because it adopts the steel bowl cover body, push rod component and seal ring, thereby bearing capacity is strong, the pressure that leakage-baffling device bears can be greater than the pressure of gas in the steel cylinder, can be promptly cover the valve that leaks air is whole, the gas complete closed of revealing is lived, can effectively solve LPG (liquefied petroleum gas) valve and body joint and the ring wear of valve own etc. and reveal the leak stopping problem of hidden danger, and can realize emergency processing is carried out in the gas leakage of all kinds of steel cylinders the risk that the reduction accident occurs; This apparatus structure is simple, and easy operating is easy to use, is particularly suitable for emergency processing, finds through correlation test, can finish leak stopping work within one minute, and not need the professional and technical personnel, and general personnel can operate; The characteristics such as this device also has the manufacturing of being convenient to owing to simple in structure, and cost is low.
Description of drawings
Fig. 1 is the structural representation of the leakage-baffling device for cylinder valve described in the utility model.
Embodiment
By describing technology contents of the present utility model, structure characteristics in detail, being realized purpose and effect, below in conjunction with mode of execution and cooperate accompanying drawing to give in detail explanation.
The better technical application scheme of a kind of leakage-baffling device for cylinder valve described in the utility model now is described in further detail: a kind of leakage-baffling device for cylinder valve in conjunction with Fig. 1, steel bowl cover body 1 and push rod component 2, steel bowl cover body 1 is used for covering the whole valve (not shown) of steel cylinder 3, push rod component 2 is used for fixedly steel bowl cover body 1, the cup of steel bowl cover body 1 is along being inlaid with seal ring 11, the middle part, the cup end of steel bowl cover body 1 is provided with screw (not shown), push rod component 2 comprises the threaded mandrel 22 that promotes cross bar 21 and vertically be located in lifting cross bar 21 middle parts with screw thread, the top of threaded mandrel 22 is provided with operating stem 23, the bottom of threaded mandrel 22 and the corresponding setting of screw on the steel bowl cover body 1, the two ends that promote cross bar 21 are provided be used to the hook 24 on the guard ring handle 32 that is articulated in steel cylinder 3.Threaded mandrel 22 also can be provided with screw shell (not shown) with screw 12 threaded connection places, if behind the thread abrasion, only needs to change screw shell just passable.
The working principle of leakage-baffling device described in the utility model and actual using method are summarized as follows:
Step 1: the foreign matter around the valve interface of first rapid cleaning steel cylinder 3, guarantee when seal ring 11 on the leakage-baffling device is with steel cylinder 3 Surface Contact seamless;
