Abstract

A casting pipe self-anchored interface belongs to an interface structure of piping connected by K-shaped casting pipe. A sealing ring is placed in a groove in the casting pipe faucet; a socket of the other casting pipe is inserted into the casting pipe faucet, which tightly presses the sealing ring between the casting pipe faucet and the socket; a gland is sheathed on the outer cylinder surface of the socket close to the faucet end surface of the casting pipe; a locking threaded hole is evenly distributed along the gland radial direction; the axial direction and the locking threaded hole is interruptedly arranged with a T-shaped bolt hole; the faucet end surface corresponding to the T-shaped blot hole is provided with a bolt hole; the outer cylinder surface of the locking threaded hole close to the socket is a grove; the groove can be glidingly provided with a press block; the locking threaded hole is screwed with a locking screw bolt; the inner end of the locking screw bolt is pressed on the press blocks; one end of the gland close to the sealing ring is provided with a convex shoulder; the convex shoulder is sustained on the sealing ring with better sealing effects. The interface has advantages of simple structure, convenient processing and manufacture, realization of multi-piping integral hoisting, convenient construction, as well as no detachment for leakage.

Description

Cast tube self-anchored type interface

(1), technical field

The utility model relates to the interface structure that a kind of K type cast tube connects into pipeline.

(2), background technique

At present, when connecting into pipeline with K type cast tube, put into seal ring in the bellmouth inner groovy of cast tube, the socket of another root cast tube inserts in the bellmouth of described cast tube, seal ring tightly is squeezed between the bellmouth and socket of cast tube, realizes sealing and anti-slip with this.But cast tube can only be constructed when being linked and packed one by one, and efficient is low, and the pipe laying ditch width that need dig is big, wastes time and energy, and is long in time limit.Owing to construct in the pipe laying ditch, work is inconvenient, environment is poor.The pipeline bearing capacity of completing is poor, and anti-radial deformation is poor.Raise or reduce and when cast tube length is changed, occur owing to the socket slippage of cast tube is leaked easily in the material temperature of carrying.This in pipeline river crossing, lake or the construction of crossing over mountain after mountain slippage repeatedly takes place leaks and do over again, increase greatly and come cost, prolonged the duration.

(3), summary of the invention:

In order to overcome the shortcoming of prior art, the utility model provides a kind of K type cast tube self-anchored type interface, and it is not only simple in structure, easy construction, and can realize many pipeline integral hoistings, the efficiency of construction height can use in all case.

The technical scheme in the invention for solving the technical problem is: put into seal ring in the bellmouth inner groovy of cast tube, the socket of another root cast tube inserts in the bellmouth of described cast tube, seal ring tightly is squeezed between the bellmouth and socket of cast tube, be with differential on the socket external cylindrical surface near described cast tube bellmouth end face, differential radial equipartition locking screw pit, axial and locking screw span is furnished with T type bolt hole, on the bellmouth end face corresponding bolt hole is arranged with T type bolt hole, be inserted with T type bolt in the T type bolt hole, T type bolt is inserted between the bolt hole of described bellmouth end face and the T type bolt hole on the differential, differential and bellmouth are fixed together, described locking screw pit is a groove near the socket external cylindrical surface, be equipped with slidably in the groove and press soon, locking screw pit inward turning is closed lock bolt, on the inner of lock bolt is pressed in soon, screw lock bolt, press and press the socket external cylindrical surface soon, differential and socket are fixed as one, two cast tubes that will be connected by differential are fixed together, described differential has convex shoulder near an end of described seal ring, convex shoulder withstands on the seal ring, and sealing effect is better.

Owing to adopt differential self-anchored type structure, so simple in structure, easily manufacturing can realize many pipeline integral hoistings, easy construction.The pipe laying ditch width that need dig is slightly larger than the cast tube diameter and gets final product, and can shorten auxiliary time greatly.Owing to construct outside the pipe laying ditch, environment is good, easy construction.The pipeline bearing capacity of completing is big, can prevent radial deformation.Raise or reduce and when cast tube length is changed, can not occur in the material temperature of carrying owing to the socket slippage of cast tube is leaked.But extensive use and pipeline river crossing, lake or the abominable occasion of environment such as cross over mountain after mountain.

(4), description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is the utility model plan view;

Fig. 2 is the utility model left view.

(5), embodiment

Put into seal ring 5 in bellmouth 6 inner groovies of cast tube, as shown in Figure 1, 2, the socket 12 of another root cast tube inserts in the bellmouth 6 of described cast tube, seal ring 5 tightly is squeezed between the bellmouth 6 and socket 12 of cast tube.Be with differential 3 on socket 12 external cylindrical surfaces near described cast tube bellmouth 6 end faces, differential 3 radial equipartition locking screw pits, axial and locking screw span is furnished with T type bolt hole, on bellmouth 6 end faces corresponding bolt hole is arranged with T type bolt hole, be inserted with T type bolt 10 in the T type bolt hole, T type bolt 10 is inserted between the bolt hole of described bellmouth 6 end faces and the T type bolt hole on the differential 3, and differential 3 and bellmouth 6 are fixed together.Described locking screw pit is a groove 9 near socket 12 external cylindrical surfaces, is equipped with slidably in the groove 9 to press fast 1.

For increase press fast 1 with the frictional force of socket 12 external cylindrical surfaces, press fast 1 to be designed to zigzag fashion with the cross section 7 of socket 12 external cylindrical surface contacting points, can also with socket 12 external cylindrical surfaces of pressing fast 1 contacting point on have anti-slip groove 8.Press fast 1 easily assembling in order to make, briquetting 1 uniformly at intervals can be connected with rubber 11 in rubber mold, its objective is both to have guaranteed easy assembling, can make each briquetting 1 energy independent deformation again, thereby socket 12 is compressed.

Described locking screw pit inward turning is closed lock bolt 2, and the inner of lock bolt 2 is pressed on fast 1.It is fast 1 that one of best two lock bolts, 2 roof pressure are pressed, and be pressed in one and press fast 1 two ends.Screw lock bolt 2, press fast 1 to fix with socket 12 external cylindrical surfaces, differential 3 and socket 12 are fixed as one, two cast tubes that will be connected by differential 3 are fixed together.Described differential 3 has convex shoulder 4 near an end of described seal ring 5, and convex shoulder 4 withstands on the seal ring 5, and sealing effect is better.
