Abstract

The utility model relates to a fast broken tube gag used for plugging a tube head when a water tube is broken. The utility model solves the technical problems that the existing broken tube gag needs to be improved, and has the defects of high labor intensity, labor and material waste and complete water stop during operation. The utility model provides a fast broken tube gag with simple and convenient operation. The fast broken tube gag is provided with a barrel-shaped broken tube clogging cap. The utility model is characterized in that a sealing gasket is arranged in the bottom of the broken tube clogging cap, and a connecting flange is arranged on the edge of the cap. Two semicircular flange clamps are arranged on the connecting flange, and can be fast fixed to a broken tube, and the broken tube clogging cap can be connected with the flange clamps with water under the conditions that the pressure of a tube net is small and water supply can not be cut off completely. The loss caused by the water stop of the large areas of the tube net is avoided, and the utility model has the advantages of easy operation, fast connection, labor saving, energy saving and low cost of the tube, and is favorable for reducing construction cost.

Description

The rapid-mounted pipe plug that breaks

Technical field

The utility model belongs to a kind of pipe plugging device, particularly a kind of when water pipe disconnects the disconnected pipe plug of the rapid-mounted of shutoff tube head.

Background technique

Along with the development in city, the water supply network in city also needs constantly to be adjusted, and some no water pipe needs to disconnect and block, to avoid the loss of water resources.At present, kill when stifled at disconnected pipe, usually adopt local mode of cutting off the water, promptly only a part of water supply network is closed, then, no pipe network is disconnected, on disconnected tube head, after pushing fiber crops violently between disconnected pipe and the cap, irritate plumbous again with the cap sleeve of a tubbiness, and the plumbous ramming that will pour into is closely knit, till water-tight.The problem that this disconnected pipe blocking device and shutoff mode exist is, 1, because public supply mains are ring-type, therefore, when needs are cut off the water, usually all can not stop fully, that is to say, in the pipe network of closing, also can constantly have some current to come out, and the valve on the water supply network all is not open for a long time, close once, so, when closing, also be difficult to it is closed tight, and pass water is not thorough, then Cao Zuo difficulty is just very big, if the water that flows out is with a point pressure slightly, then shutoff work just can't be carried out, and that is to say this blocking device to having relatively high expectations of cutting off the water, for the pipe shutoff of breaking, sometimes even need large size to cut off the water, thus influence the normal water supply in city.2, labor intensity, and the difficulty of operation big, the time that needs is long, personnel are many, the material that expends is many, the expense height can't adapt to the needs of public supply mains transformation.

Summary of the invention

The technical problems to be solved in the utility model is, existing disconnected pipe plug is improved, overcome its labor intensity big, take a lot of work, take material, and the problem that must cut off the water fully when operating, a kind of rapid-mounted easy and simple to handle pipe plug that breaks is provided.

The utility model has a barrel-shaped disconnected pipe shutoff cap, and its special way is, at the bottom of the cap of disconnected pipe shutoff cap sealing gasket is housed, and adpting flange is arranged on the hat brim, and two semicircular flange clips are housed on adpting flange.

Two semicircular flange clips can be very fast be fixed on disconnected pipe place, under the situation that disconnected pipe shutoff cap then can be less at ductwork pressure, can not thoroughly cut off the water, band water is finished and being connected of flange clip, avoided the loss of cutting off the water and causing because of the pipe network large size, and, easy and simple to handle, connect rapidly, saving of labor, cost laborsaving, pipe fitting be low, helps reducing engineering cost.

Description of drawings

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the right elevation of Fig. 1;

Fig. 3 is the structural representation of another embodiment of the utility model.

Embodiment

Embodiment 1:

As depicted in figs. 1 and 2, the utility model has a barrel-shaped disconnected pipe shutoff cap 1, in at the bottom of the cap of disconnected pipe shutoff cap 1, sealing gasket 2 is housed, adpting flange is arranged on the hat brim, two semicircular flange clips 4 are housed on adpting flange, are connected with bolt 3 between the adpting flange on flange clip 4 and the disconnected pipe shutoff cap 1 and are fixed together; Link together with bolt 5 between two flange clips 4, and be fixed on the disconnected pipe place of pipe network; Jackscrew 6 also is housed on flange clip 4, makes flange clip 4 more reliable with being connected of pipeline.

During use, determine earlier the position of disconnected pipe, again two flange clips 4 are fixed on the suitable position, and bolt on 5 and jackscrew 6, then, with hacksaw or the disconnected pipe of swaging clamp, the section of disconnected pipe must be flat mouthful, and is water-tight to guarantee it, at last, the pipe shutoff cap 1 that will break is enclosed within on the disconnected pipe, bolts on 3 to get final product.

Embodiment 2:

As shown in Figure 3, its structure such as embodiment 1, difference is to also have a valve 7 at the bottom of the cap of disconnected pipe shutoff cap 1, and valve 7 can be released the water in the pipe that breaks, close not thorough at pipe network, when the hydraulic pressure in the disconnected pipe is big, earlier valve 7 is opened, after disconnected pipe shutoff cap 1 fixes with flange clip 4, valve 7 is closed, disconnected pipe can be closed again.

Claims

1, the disconnected pipe plug of a kind of rapid-mounted, it has a barrel-shaped disconnected pipe shutoff cap, it is characterized in that, at the bottom of the cap of disconnected pipe shutoff cap sealing gasket is housed, and adpting flange is arranged on the hat brim, and two semicircular flange clips are housed on adpting flange.

2, the disconnected pipe plug of rapid-mounted according to claim 1 is characterized in that, also has a valve at the bottom of the cap of disconnected pipe shutoff cap.
