Abstract

The utility model relates to a pipe blocking device for repairing a pipeline, which is called a clamping section, and is composed of two symmetrical parts of clamping bodies, a clamping gland, a sealing ring, a sealing strip and a fastening piece. The inner cavity and the external part of the clamping body present a V shape respectively; the connecting position of a flange of a mouth cavity of the clamping body and the gland adopts a concave-convex shape engaged with the sealing ring. The engagement position of the upper clamping body and the lower clamping body is sealed by the sealing strip, and the upper clamping body and the lower clamping body are fastened into integration by a screw bolt and a nut. The structure is simple, and the operation is convenient. The utility model can be used for the water leakage accident and the air leakage accident created by the transversal fracture and the longitudinal fracture of the sand holes and the air holes of the water supply and drainage pipeline, various liquid pressure conduits, and gas pressure conduits. The utility model has the advantages of labor saving, time saving and cost saving.

Description

The pipe plugging device

The utility model relates to the pipe plugging device (claiming the card knot cluster again) that a kind of pipe-repairing is used.

In the using process of various pipelines, because the potential risk of original cast iron, steel pipe causes that trachoma, pore expose and forms pipe leakage or cause landform to be sunk or factor such as temperature difference variation causes pipeline break because of geographical change, often solve with cement and fibrous material parcel, effect is not so good, so when the pipeline infiltration occurring and rupturing just to have only to cut off the water changes pipe, take a lot of work, take material, bring difficulty and loss for production and life, can so, develop a kind of device that is used to rush to repair such accident?

The purpose of this utility model provides a kind of pipe plugging device to the public exactly, can be widely used in the trachoma, pore of industry, electric power, oil, boats and ships, chemical industry, railway, plumbing and various liquid, gas, heat distribution pipeline, laterally, the accident maintenance that causes of longitudinal fracture.

The purpose of this utility model is achieved like this, form by two parts symmetrical card complex, the multiple differential of card, seal ring, Stamping Steel Ribbon, fastening piece, the card complex is its oral cavity internal diameter with outer diameter tube, inner chamber is a V-type, to solve distortion, the dislocation that forms because of pipeline break, card complex oral cavity flange is connected with concave-convex shape and seal ring mutually with the multiple differential joint of card, and upper and lower card complex joining place adopts the Stamping Steel Ribbon sealing, to realize the effect of instantaneous leaking-stopping.Two parts symmetrical card complex is solidified as a whole by fastener bolt, nut.

The utility model structure tube list, easy to use, seepage and the fracture that can rush to repair pipeline fast, saving of work and time can reduce maintenance expenses and wide variety of materials, fund input in a large number.

Below in conjunction with accompanying drawing structure of the present utility model is elaborated.

Fig. 1 is the utility model front view.

Fig. 2 cuts right elevation open for A-A position among Fig. 1.

Half cuts bottom view open to Fig. 3 for B-B position among Fig. 1.

Given by Fig. 1, the utility model is by two parts symmetrical card complex 1, differential 2, clamping bolt 4, nut 5 constitutes, card complex 1 is its oral cavity internal diameter with outer diameter tube, inner chamber is a V-type, be beneficial to solve the distortion that forms because of pipeline break, dislocation, on the accent of card complex two ends oral cavity flange 9 is arranged, oral cavity flange 9 interior fluted 10, be placed with seal ring 6 in the groove 10, as shown in Figure 3, the multiple differential 2 of card that oral area is convex is equipped with bolt 4 and nut 5 in flange 9 outsides in oral cavity, constitutes the concavo-convex linking mutually of seal ring, the card complex, differential, seal ring all is two parts symmetrical, two-part card complex is solidified as a whole with clamping bolt 7 up and down, clamping bolt 7 inner faces are equipped with Stamping Steel Ribbon 3, and as shown in Figure 2, the card complex is outside V-shaped and stiffening rib 8 arranged.Stamping Steel Ribbon, ring all adopt rubber to make, and other each parts all adopt metallic material to make, and as steel, iron etc., can certainly adopt duroplasts or other material to make.

In a word, its structure of the utility model is, there is flange 9 at two parts symmetrical card complex 1 two ends on the oral cavity, flange 9 oral cavities locate fluted 10, sealing bad 6 is arranged in the groove 10, the multiple differential 2 of card that oral cavity portion is male type is equipped with bolt 4 and nut 5 in the outside, constitute the concavo-convex linking mutually of seal ring, upper and lower card complex is solidified as a whole with clamping bolt 7, clamping bolt 7 inner faces are equipped with Stamping Steel Ribbon 3, and card complex outside is V-shaped, and stiffening rib 8 is arranged, card complex inner chamber is also V-shaped, is beneficial to repair distortion, the dislocation that forms because of pipeline break.
