Description

Intervention type bidirectional expansion multifunctional leaking stoppage gun
Technical Field
The utility model belongs to the technical field of the leaking stoppage rifle and specifically relates to a multi-functional leaking stoppage rifle of intervention formula two-way inflation is related to.
Background
In the storage and transportation link of hazardous chemicals, facilities such as hazardous chemical storage tanks and pipelines are prone to leakage in the forms of perforation, tearing, crevasse and the like due to equipment faults, improper operation, traffic accidents, accidental collisions and the like, and aiming at emergency treatment of the leakage, the existing fire rescue team usually adopts wood wedges to temporarily block point-shaped, linear or crack leakage, but due to irregular leakage holes or cracks, the sealing of the plugging fit surfaces of the wood wedges is not tight. In addition, fire rescue teams are generally provided with high-pressure agent injection leaking stoppage guns, and the leaking stoppage tool achieves the purpose of stopping leaking of leaking points by injecting glue outside the leaking points after the leaking points are fixed by using a clamp. The technical scheme of the injection agent leaking stoppage gun comprises a matching scheme of an injection clamp and an injection gun, the fixing clamp is used for leakage treatment caused by the failure of a sealing gasket of a connecting flange, and the scheme has the following preconditions: a steel fixture which is tightly matched is manufactured in advance, a plurality of glue injection holes are uniformly distributed on the circumference of the fixture, glue rods (different in quality) of a 100mm unit are pushed into a space constructed by the fixture and a flange by using hydraulic pressure provided by a high-pressure hydraulic plunger pump after the fixture is fixed on the flange, and the space is filled in stages to stop medium leakage. The fact proves that the fixture matching can not completely construct an ideal 'sealing box', and the leakage is difficult to avoid because the gap between the connecting bolt and the matching gap between the fixture and the flange circumference are difficult to eliminate. Another factor is that each glue injection point is difficult to fill uniformly with equal pressure, and even local overpressure causes perforation of the gasket. Moreover, the leakage point of the container cannot be used by the scheme, so that the traditional glue injection gun has no possibility of operation. The high-pressure injection agent leaking stoppage gun has the advantages of complex structure, complex operation, long leaking stoppage operation time, high requirements on a matched clamp in the use process, high requirements on skills and experience of operators, certain limitation on the use convenience and safety of the high-pressure injection agent leaking stoppage gun, large difference of required sealing injection amount and low success rate due to the influence of a clamp sealing cavity structure. The original design of the glue injection leakage stopping gun is a treatment means aiming at the failure of a sealing gasket of a high-temperature high-pressure non-stop chemical flange, and has no general significance for rescue treatment of dangerous chemical leakage of the existing fire rescue team. Particularly, in the face of emergency rescue treatment of leakage of uncertain opening hole gaps of container pipelines, the existing wood wedge leakage stopping device is a main tool in actual combat operation, but the material property of the wood wedge leakage stopping device determines the low efficiency and difficulty of the device in the treatment process and brings great safety risk to rescue workers.
