Description

Clamping type pipeline quick blocking external member

Technical field

The utility model relates to a kind of clamping type pipeline quick blocking external member; Particularly relate to a kind of when the pipeline generation breakage of conveyance fluid; Do not stopping under the pipeline work prerequisite, the clamping type pipeline quick blocking external member that just can repair fast belongs to mechanical engineering field.

Technical background

As everyone knows, various damage leakage accidents in use often take place in pipeline, will cause economic loss as long as leak, and must adopt leaking-stopping measure leak stopping as early as possible effectively.Usually the leak stopping way of steel pipe is welding; In the pipeline repair welding that breach and crack occur; But there is following problem in the repair welding method: repair welding necessarily requires pipeline to stop fed sheet of a media on oil-gas pipeline, otherwise repair welding on the pipeline of transporting water is blasted in the repair welding meeting; Usually can't operate, also need pipeline to stop fed sheet of a media because the water column ejection is arranged at the breach place.Pipeline is out of service just must to bring economic loss.

This shows that welding is not the desirable way of repairing pipe leakage.Will be higher and more renew the financial cost that pipe follows.

In recent years; The also useful pipe clamp that is the Hough shape is repaired broken pipe; Its way is that elder generation is connected the upper and lower pipe clamp that both sides have Sealing on the pipeline with bolt; Tight a bolt, the Sealing at two is contained in by upper and lower pipe clamp closes up in the seal groove that the back forms then, reach sealing effect thereby refill Hough formula briquetting and utilize many bolts to tighten up briquetting.But this structure, mode are used to repair broken pipe, its production, install all complicatedly, and coupling is too much, and its sealing is not in place and phenomenon that occur leaking happens occasionally.

Above-mentioned existing repairing blocking method about pipe leakage exists defective and deficiency really, demands urgently improving and perfect.

In view of the ubiquitous technical problem in above-mentioned existing pipe first-aid leak stopping aspect; The clamping type instantaneous leaking-stopping device of the utility model can be realized the instantaneous leaking-stopping of pipeline under the situation that does not stop pipeline work, can weld; Do not change pipeline; Without bolt connection mode, convenient and swift, have more high efficiency.

Summary of the invention

The main purpose of the utility model is, overcomes existing defective in the existing pipe plugging emergency repair method, and a kind of novel clamping type pipeline instantaneous leaking-stopping device is provided.Technical problem underlying to be solved is not stop the purpose that normal operation can realize instantaneous leaking-stopping at pipeline; And realized not using the conventional bolt clamping mode that is connected and fixed, saving of work and time reduces the pipe plugging workload greatly; Greatly shorten plugging time, reduce economic loss.

For reaching solution in the technical problem that does not stop to realize quickly and easily under the pipeline working condition pipe plugging; The utility model adopts following technological scheme: a kind of clamping type pipeline quick blocking external member; Be made up of closed ring and blocking device, blocking device is fixed on the closed ring through screw bolt and nut.Wherein:

Closed ring is made up of left semi-ring, right semi-ring and stub axle; Form the main body of pipe plugging; Extending below also on the surface layer of left side semi-ring and right semi-ring, warp becomes the warp auricle; Form under warp auricle on the left semi-ring, the left semi-ring on warp auricle, the right semi-ring warp auricle under the warp auricle and right semi-ring respectively, the edge of warp auricle becomes to be fixedly connected with surface layer; The stub axle is positioned at the following warp auricle of left semi-ring and right semi-ring, and through the stub axle left semi-ring and right semi-ring is linked together.

Blocking device is made up of base fixed pin shaft, handle base, rivet, handle, handle bearing pin, U-shaped degree of tightness pull bar, grab, adjusting nut, fixing bolt and nut.The base fixed pin shaft is positioned at warp auricle on the right semi-ring, on the right semi-ring on warp auricle and the base fixed pin shaft corresponding part be provided with the screw that penetrates entirely, be connected with handle base through screw bolt and nut; Handle is connected with handle base through the handle bearing pin; Handle connects with handle base through rivet and can rotate by thorny handle base; Grab is fixed on the left semi-ring on the warp auricle through screw bolt and nut; The handle bearing pin passes handle, and handle bearing pin both sides are respectively arranged with hole; The U mouth end of U-shaped degree of tightness pull bar passes the hole at handle bearing pin two ends respectively; The U mouth end of U-shaped degree of tightness pull bar is respectively arranged with screw thread; Through regulating the coupling mechanism force nut U-shaped degree of tightness pull bar is fixed on a certain position, this coupling mechanism force nut is used for the coupling mechanism force of regulating handle; The U-shaped of U-shaped degree of tightness pull bar bottom can be free chimeric with the draw-in groove on the grab, when on when raising one's hand handle, separate with grab the U-shaped bottom, when pressing down handle, the U-shaped bottom is chimeric with the draw-in groove in the grab, reaches the purpose of tension left and right sides semi-ring.

Described left semi-ring and right semi-ring, its inner side surface also is embedded with rubber sheet gasket, and then guarantees the leakproofness of shutoff.

Compared to prior art; The clamping type pipeline quick blocking external member of the utility model; Can be implemented under the situation that does not stop pipeline work, not use Bolt Connection to tighten mode, use the connecting rod clamping means just can conveniently carry out pipe plugging; Greatly save maintenance man-hours, reduced economic loss.
