Description

The pipe leakage locking device

Technical field

The utility model relates to a kind of pipe leakage prosthetic appliance, particularly a kind of pipe leakage locking device that the pipeline that leaks is carried out shutoff.

Background technique

Medium is on the fluid pipeline of media such as water, oil, gas, acid, the long-time use, the pipeline incident of leakage can take place unavoidably, when originally taking place to leak on the pipeline body, processing method is the method with electric welding, at the leakage point of pipeline, dissolve autocratic Fe welding rod with electric heating, shutoff fuses mutually with the pipeline of leakage point on leakage point, forms shutoff.This method need stop and emptying medium and stopping production, also to cooperate electricity consumption, and need professional welding personnel to carry out operation, just can accomplish sealing to leakage point, cost height like this, the time is long, area of influence is big, sometimes in order to keep producing or producing needs, can postpone the operation of maintenance leak stopping, can stay the hidden danger that may make the fracture propagation of pipe leakage point like this, cause bigger potential safety hazard.

The model utility content

For addressing the above problem, the utility model provides a kind of pipe leakage locking device, can onlinely need not stop that the leakage point to pipeline in time carries out shutoff under the situation of medium.

For achieving the above object, pipe leakage locking device of the present utility model comprises: the split type sleeve, and two split type sealing pressure heads and two groups of split type seal rings, described split type sleeve middle part is provided with the flange that extends internally; Described two split types sealing pressure head places the two ends of described split type sleeve respectively, is connected with described split type bush whorl; Described two groups of split type seal rings are separately positioned between the flange of described split type sealing pressure head and split type sleeve, and every group of described split type seal ring is made of a plurality of seal ring stacks.

The section configuration of described seal ring is a V-arrangement.

The junction point of described split type sleeve is provided with sealing gasket.

Described split type sealing pressure head is provided with handle.

Pipe leakage locking device of the present utility model can finish being assembled into integral body from leakage point just at a distance when implementing, the medium that can avoid leaking is mapped on one's body the maintenance construction personnel.Make its expansion by compressing V-arrangement split type seal ring, reach, thereby the leakage point of this segment pipe is enclosed in the pipe leakage locking device of the present utility model totally-enclosed between pipeline and the split type sleeve.Simultaneously pipe leakage locking device of the present utility model has and connects and the whole effect that tightens pipeline, and the crack that can protect the pipeline leakage point is extending no longer.

Pipe leakage locking device of the present utility model can onlinely need not stop medium transport, and not arrestment operation is accomplished under the situation that does not stop to produce, and can ensure production safety, continuous, long-acting operation.

Embodiment

The schematic representation that Fig. 1 carries out shutoff for pipe leakage locking device of the present utility model to the pipe leakage point, Fig. 2 are the decomposing schematic representation of pipe leakage locking device among Fig. 1.Referring to Fig. 1～2, pipe leakage locking device of the present utility model comprises: 11, two split type sealings of split type sleeve pressure head 13a, 13b, and two groups of split type seal ring 12a, 12b, described split type sleeve 11 middle parts are provided with the flange 111 that extends internally; Described two split types sealing pressure head 13a, 13b place the two ends of described split type sleeve 11 respectively, are threaded with described split type sleeve 11; Described two groups of split type seal ring 12a, 12b are separately positioned between the flange 111 of described split type sealing pressure head 13a, 13b and split type sleeve 11, and every group of described split type seal ring 12a, 12b are made of a plurality of seal ring stacks.

Described split type sealing pressure head 13a, 13b are provided with handle 131,132, and convenient described split type sealing pressure head 13a, 13b screw.

The section configuration of described split type seal ring 12a, 12b is a V-arrangement.Described split type seal ring 12a, 12b play the effect of sealing being subjected to the flange 111 extruding back radial dilatation of described split type sealing pressure head 13a, 13b and split type H shape sleeve 11.The subdivision otch of each seal ring of described split type seal ring 12a, 12b adopts arranged in dislocation, guarantees good sealing property.

Fig. 3 is the left view of split type sleeve among Fig. 2.As shown in the figure, two-part of described split type sleeve 11 can connect by bolt, also can adopt other conventional Placements.The junction point of described split type sleeve 11 preferably is provided with sealing gasket, prevents dielectric leakage.

Pipe leakage locking device of the present utility model referring to Fig. 1, at first is contained in each parts on the pipeline 100 with a certain distance from the place of leakage point 101 in use in advance, finishes the parts combination, does not screw earlier described split type sealing pressure head 13a, 13b this moment; And then move on to leakage point fast, and reach leakage point 101 to be sealed, make leakage point 101 between described split type seal ring 12a, 12b; Screw described split type sealing pressure head 13a, 13b at last, finish shutoff leakage point 101.Pipe leakage locking device of the present utility model is enclosed within sealing leakage point 101 on the pipeline to be repaired 100, and protects the no longer expansion of this pipe leakage point 101 to damage.
