Abstract

The utility model relates to a fast lash-up leakage stopper, which comprises a narrow neck bolt with a crescent eccentric head, a spring washer, a groove shaped washer and a butterfly nut. The utility model can be used to stop the holes on the equipments and pipe-lines to transport or store oil, gas and water with the pressure less than 20 kg/cm<2> and the wall of the container between one hundred millimeters and one thousand millimeters. The utility model has the advantages of simple structure, low manufacture cost, convenient use and fast stop.

Description

Emergent rapid plugging device

The utility model relates to a kind of leak stopping device.

In order to satisfy pressure is no more than 20kg/cm ²The pressurized container and the repairing of pipeline need, reduce to greatest extent fluid because of container perforation cause excessive, generally all need use the emergency leakage blocking device, and existing emergency leakage blocking device is made by cast iron, the cost height, and manufacture difficulty is big, on the other hand, because the volume of existing cassette emergency leakage blocking device is bigger, and is effective to the leak stopping of pipeline, then powerless to the perforation of container class equipment.

At the problems referred to above, the utility model provides a kind of emergent rapid plugging device, utilizes engine lathe to make, and is easy to use, cost is low, plugging effect good, applicable to the leak stopping of various containers and pipeline.

For achieving the above object, the technological scheme that the utility model adopted is:

Anxious rapid plugging device is made up of neck screw, elastic washer, grooved packing ring, wing nut four parts of the eccentric cap of band crescent shape, wherein the flute profile gasket sleeve is on neck screw, elastic washer is between eccentric cap of crescent shape and grooved packing ring, and wing nut is threaded with neck screw in the back of flute profile packing ring.During use the eccentric cap of the crescent shape of leak stopping device is stuck in hole inside, screws wing nut, the pressure by bolt and wing nut produce acts on the elastic rubber fitting, reaches the purpose of shutoff shell hole.

Emergent rapid plugging device has adopted the technology of eccentric displacement, i.e. the eccentric cap of crescent shape, and the bolt neck is processed into the thin neck with certain intensity, make it when any angle, the eccentric cap of crescent shape can both pass hole smoothly, is stuck in hole inside, thereby realizes the purpose of instantaneous leaking-stopping.

Below in conjunction with accompanying drawing the utility model being done one describes in detail:

Fig. 1 is a plan view of the present utility model.

As shown in Figure 1, emergent rapid plugging device is made up of neck screw 2, elasticity oil resistant rubber packing ring 3, grooved packing ring 4, wing nut 5 four parts of the eccentric cap 1 of band crescent shape, during use the eccentric cap 1 of crescent shape is snapped in hole inside, screw wing nut 5, pressure by bolt 2 and wing nut 5 generations, compress elasticity oil resistant rubber packing ring 3, reach the purpose of shutoff hole.

Claims

1, a kind of emergent rapid plugging device, it is characterized in that: neck screw, elastic washer, grooved packing ring, wing nut four parts by the eccentric cap of band crescent shape are formed, wherein the female gasket sleeve of groove is on neck screw, elastic washer is between eccentric cap of crescent shape and grooved packing ring, and wing nut is threaded with neck screw in the back of flute profile packing ring.
