Abstract

A rigid pipe clamp is used for quickly connecting and repairing pipes. The rigid pipe clamp comprises a pipe clamp and comprises two or more arc pieces, and the arc pieces are connected in the circular direction to form a whole circle; the pipe clamp is in conical surface assembly with pipe ends, and the locking force is big and distributed evenly; a seal groove is arranged on a horizontal end surface of one pipe end of the two mutually connected pipe ends; and a seal ring is pre-placed in the seal groove to prevent the seal ring from easily dropping off, and the sealing performance is excellent. The rigid pipe clamp is fastened through a lock bolt and a nut. The rigid pipe clamp solves the fixing problem of a sealing gasket; connecting screw holes are easy to center; the number of connecting bolts are greatly reduced, and the bolts are convenient to fasten; and the requirement on the centration of the connected pipes is low. The rigid pipe clamp has wide application range, and is suitable for the quick connection of all sorts of metal pipes and nonmetal pipes.

Description

A kind of rigidity pipe clamp

Technical field

The utility model relates to a kind of tubing and connects pipe clamp, especially a kind ofly is used for the rigidity pipe clamp that tubing connects fast, repairs.

Background technique

Pipes connecting method at present commonly used has: flange connects, socket joint connects, pipe clamp connects and be welded to connect.

There are the following problems in the flange connection: sealing gasket is difficult to fix; The bolt of required installation is more; The bolt hole that is connected is difficult to centering, the bolt penetration hole difficulty; It is fastening fully be difficult to by installing space restriction bolt, and it is fastening to be difficult to symmetry, influences the joint bearing capacity; Sealing gasket is easy to dislocation, and the tubing that is connected also is easy to dislocation, has strengthened the pressure loss of pipeline.

There are the following problems in the socket joint connection: the tubing that is connected needs basic centering, has so strengthened the pipeline construction difficulty; The joint bearing capacity is not high, improves bearing capacity as desire, need install clamp flange in addition additional, has strengthened investment, has increased difficulty of construction.

There are the following problems in the pipe clamp connection: need join the standard pipe end, and need in advance pipe end is welded on the tubing, weld is perishable, need do preservative treatment.This method investment is big, and difficulty of construction is also big.

Be welded to connect that there are the following problems: since tubing cross-sectional dimension irregularity, tubing location difficulty, the welding difficulty; Weld is perishable, and is difficult to do preservative treatment.

Pipe repairing method commonly used at present has: steel pipe adopts welding method more; Plastic tube adopts replacing tubing more; Glass Steel Tube adopts winding method more.The product that is used for pipeline rehabilitation on the market is still rare.

Therefore, be necessary to design a kind of rigidity pipe clamp that tubing connects fast, repairs that is used for.

Summary of the invention

The purpose of this utility model is to provide a kind of rigidity pipe clamp that tubing connects fast, repairs that is used for.

For this to above-mentioned purpose, the utility model rigidity pipe clamp is made up of pipe clamp, seal ring, pipe end (about each one) and lock bolt.

Pipe clamp is made up of two or more circular arc spares, and circular arc spare is connected at hoop, forms a full circle.

Pipe clamp and pipe end are conical surface assembling, and coupling mechanism force is big and be even distributed force.

In two pipe ends that are connected, there is a horizontal end face of pipe end to have seal groove.Seal ring is put into seal groove in advance, difficult drop-off, and good airproof performance.

The rigidity pipe clamp is to make of steel or spheroidal graphite cast iron.

The rigidity pipe clamp is fastening by lock bolt and nut.

Compared with prior art, the present invention has fully absorbed socket joint and has connected the advantage that is connected with pipe clamp, has solved the sealing gasket fixation problem; Connect screw and be easy to centering; Significantly reduced the quantity of connecting bolt, and bolton is convenient; Save the installation time greatly, improved work efficiency.

Description of drawings

Fig. 1 is a transverse sectional view of the present utility model;

Fig. 2 is a side view shown in Figure 1;

Embodiment

Below in conjunction with the drawings and specific embodiments the utility model rigidity pipe clamp is described further.

Please be simultaneously with reference to Fig. 1, Fig. 2, the utility model rigidity pipe clamp is connected by pipe clamp 1, seal ring 2, pipe end 3 (about each one), lock bolt 4 material that forms a whole.

Embodiment of the present utility model is: weld pipe end 3 (or bonding respectively earlier, or mechanical connection) in the tubing end, seal ring 2 is put into seal groove, use pipe clamp 1 (2) to block the pipe fitting head then, by lock bolt 4 lockings, utilize the tapering of pipe clamp internal diameter and the tapering of pipe end external diameter that seal ring is compressed, reach the purpose of quick connection.

Minor caliber pipe, pipe clamp 1 is made up of two semicircles; Heavy caliber pipe, pipe clamp 1 is made up of plural circular arc spare.

Minor caliber pipe, pipe clamp 1 both sides are respectively with a lock bolt.Heavy caliber pipe, each uses two or more lock bolts pipe clamp 1 hoop joint.

The utlity model has following characteristics: one of its characteristics are fast, conveniently. Pipe clamp and pipe end are conical surface assembling, are easy to assemble; Sealing ring is put into seal groove, difficult drop-off in advance; Clamping screw quantity is far fewer than flange, and bolted is convenient. Greatly save the set-up time, improved work efficiency.

Two of its characteristics are reliable. Pipe clamp utilizes cone locking to connect, and coupling mechanism force is big, and coupling mechanism force is even distributed force, has greatly improved the tubing connection reliability.

Three of its characteristics are that the scope of application is wide, applicable to the quick connection of various metal pipe materials, non-metal pipe.

Claims

1. one kind is used for the rigidity pipe clamp that quick tubing connects, and it is characterized in that: mainly be made up of pipe clamp, pipe end (about each one), described pipe clamp is made up of two or more circular arc spares, and circular arc spare is connected at hoop, forms a full circle.

2. the described rigidity pipe clamp of claim 1 is characterized in that pipe clamp and pipe end are conical surface assembling, and coupling mechanism force is big and be even distributed force.

3. the described rigidity pipe clamp of claim 1 in two pipe ends that it is characterized in that being connected, has a horizontal end face of pipe end to have seal groove, and seal ring is put into seal groove, difficult drop-off, and good airproof performance.
