Abstract
The present invention relates to a k-type cast pipe automatic anchor interface which belongs to interface structure used for connecting K-type cast pipes into pipelines. A sealing ring is placed in the inward recess of the socket of the cast pipe, the spigot of another cast pipe is inserted into the socket of the cast pipe, the sealing ring is tightly extruded between the socket and the spigot of the cast pipes, a pressure flange is cover-mounted on an external cylindrical surface of the spigot which is abutted on the end face of the socket of the cast pipe, locking thread holes are redially and uniformly distributed on the pressure flange, T-type bolt holes are axially distributed at the space between the locking thread holes and the pressure flange, the end face of the socket corresponding to the T-type bolt holes is provided with bolt holes, the external cylindrical surface of the locking thread holes near the spigot is recesses in which pressure blocks are movably arranged, locking bolts are screwed in the locking thread holes, the inner ends of the locking bolts are pressed on the pressure blocks, one end of the pressure flange near the sealing ring has a shoulder, the sealing ring is pushed with the shoulder, and the sealing effect is more better. The present invention has advantages of simple structure, easy processing and manufacturing, a plurality of channels integral erection, convenient construction and no surging and leaking.
Description
(1), technical field
The invention belongs to a kind of K type cast tube and connect into the interface structure of 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 invention provides a kind of cast tube self-anchored type interface, 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 present invention solves the technological scheme that its technical problem takes: 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, briquetting is housed in the groove slidably, locking screw pit inward turning is closed lock bolt, the inner of lock bolt is pressed on the briquetting, screw lock bolt, briquetting presses the socket external cylindrical surface, 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
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is a plan view of the present invention;
Fig. 2 is a left view of the present invention.
(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, and briquetting 1 is housed in the groove 9 slidably.
In order to increase the frictional force of briquetting 1 and socket 12 external cylindrical surfaces, briquetting 1 is 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 briquetting 1 contacting point on have anti-slip groove 8.For briquetting 1 is easily assembled, 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 the briquetting 1.Briquetting 1 of best two lock bolts, 2 roof pressures, and be pressed in the two ends of a briquetting 1.Screw lock bolt 2, briquetting 1 is fixed with socket 12 external cylindrical surfaces, and differential 3 and socket 12 are fixed as one, and 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.
