Abstract
The utility model discloses a new leakage stoppage plug for fire fighting. The structure of the utility model is that: the inner diameter of the tubular expansion tube diminishes from the inside to the outside; the expansion plug is provided with a cylindric expansion block at the inner end and the middle of the expansion block is provided with a pull rod which extends outside the tube and screw threads that are matching with each other are arranged on the pull rod and the outer end of the expansion tube; an soft expansion sheath covers the expansion tube. Disengagement of the leakage stoppage plug on this utility model due to great pressure from the container is totally avoided. The utility model has a simple structure and is easy to use and is applicable to such emergencies as fire fighting and suitable for longtime plugging.
Description
Technical field
The utility model relates to a kind of device for plugging, the leak-stopping plug that specifically a kind of fire-fighting is used.
Background technology
In fire-fighting work, often run into that liquid container breaks and the situation that causes leaked liquid.Be the blocking container leak, prevent from that liquid is especially inflammable and explosive to leak that stop the condition of a disaster and enlarge, the fire fighter adopts stopper to stop up leak more.Have a lot of drawbacks with the stopper leak stopping: one, stopper must be cut earlier before use and cut, and can't adapt to urgent emergency situation; Two, the front end of the stopper of Du Saiing is sharp, and the rear end is bigger, is easy to come off from leak under the pressure of liquid, is not suitable for long obstruction; Three, the elasticity of stopper is less, is difficult to leak is blocked fully.
The utility model content
The purpose of this utility model just provides easy to use, the lost circulation plug of suitable long-time leak stopping, and leak can be stopped up fully.
The utility model be achieved in that the internal diameter of tubular bulged tube from inside to outside diameter diminish gradually, be provided with cylindrical expanding block in the inner of bulged tube, there is the pull bar of protruded tube outer end at the middle part of expanding block, on pull bar is provided with the screw thread that cooperatively interacts with outer end bulged tube; On bulged tube, be coated with soft expansion sleeve.So just actv. prevents that the leak stopping chamber from coming off from leak more.In use, the utility model is inserted in the leak, then with rotating tension bars such as wrench, the pull bar that rotates with the screw thread fit of bulged tube under, outside stretching expanding block, because the internal diameter of bulged tube diminishes from inside to outside, bulged tube external diameter under the expanding block effect is become greatly gradually, thereby leak can be stopped up fully.The outer elastic expansion cover of expansion plug can block the irregular place of leak effectively.
The utility model is provided with the anti-slip ring of at least one circle on expansion sleeve.Anti-skidding setting up of going back can increase the expansion sleeve friction coefficient effectively, thereby can prevent more effectively that lost circulation plug from coming off from leak in use.
The utility model is provided with the nut that is mated in the outer end of pull bar.After adopting such structure, just can use swivel nuts such as spanner more easily, the stretching pull bar expands bulged tube, uses convenient, quick.
The utility model inner external diameter in use is greater than the outer end external diameter, and liquid or gaseous tension in the container only can make it to seal more, and it is come off, and have stopped the situation that lost circulation plug is come off because of container pressure is much fully.The utility model can made various outer diameter, can directly control with spanner etc., and is easy to use.Utilize the elasticity of expanded film, make its leak that can be suitable for different situations, and can stop up leak fully.The utility model is simple in structure, and protection is convenient, suit under the situation of urgent need leak stopping such as fire-fighting, to use, and suitable long-time leak stopping.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a cross-sectional view of the present utility model.
The specific embodiment
As shown in Figure 1 and Figure 2, the internal diameter of the tubular bulged tube 1 of this lost circulation plug diameter from inside to outside diminishes gradually, be provided with cylindrical expanding block 2 in the inner of bulged tube 1, there is the pull bar 3 of protruded tube outer end at the middle part of expanding block 2, and the outer end with bulged tube 1 on pull bar 3 is provided with the screw thread that cooperatively interacts; On bulged tube 1, be coated with soft expansion sleeve 4.During use, earlier lost circulation plug is filled in the leak place, the pull bar 3 that outwards stretches then, pull bar 3 be outwards slip bulged tube 1 in, because of the internal diameter of expand tube from inside to outside diameter diminish gradually, thereby bulged tube 1 is constantly expanded, until leak is stopped up fully.The soft expansion sleeve 4 that coats on bulged tube 1 has certain elasticity, relies on its elasticity, can better stop up leak, prevents that liquid or gas from continuing to leak.
As shown in Figure 1 and Figure 2, this lost circulation plug is provided with the anti-slip ring 5 of at least one circle on expansion sleeve 4, and anti-slip ring 5 can be the multi-turn projection of expansion sleeve itself.Prevent the friction coefficient that increases this lost circulation plug outside face effectively of setting up of slip ring 5, use safer
As shown in Figure 1, this lost circulation plug is provided with the nut 6 that is mated in the outer end of pull bar 3.
Claims (3)
1, a kind of leak-stopping plug, it is characterized in that the internal diameter of tubular bulged tube from inside to outside diameter diminish gradually, be provided with cylindrical expanding block in the inner of bulged tube, there is the pull bar of protruded tube outer end at the middle part of expanding block, on pull bar is provided with the screw thread that cooperatively interacts with outer end bulged tube; On bulged tube, be coated with soft expansion sleeve.
2, leak-stopping plug according to claim 1 is characterized in that being provided with the anti-slip ring of at least one circle on expansion sleeve.
