Abstract
The utility model provides a direct-burried and maintenance-free ball type universal compensator which comprises a front end pipe and a rear end pipe, and is characterized in that the end point of the rear end pipe is connected with a shell; the shell is internally provided with a ball connected with the end point of the front end pipe; the inside of the ball is of a hollow structure so that the front end pipe is communicated with the rear end pipe; and the outer wall of the ball and the inner wall of the shell are in relatively rotatable sealing connection. The direct-burried and maintenance-free ball type universal compensator has simple and reasonable structure as well as simple and convenient operation; in addition, the simple and practicable structure enables the compensator to be free from maintenance and is also very beneficial to widely generalization.
Description
Technical field:
The utility model relates to a kind of compensation device of directly buried pipeline, the universal compensator of ball formula that especially a kind of direct-burried is non-maintaining.
Background technique:
At present, compensator at the compensation field of directly buried pipeline majority all is directly to be fixedly installed on straight connector place, though its effect can, but directly fixing mode makes that but this mode application area is limited, the problem of its existence is as follows: 1, when running into when needing angled pipe joint, just need special compensator be set according to this angle, the angle of this pipeline remains fixing behind the compensator and be provided with, and promptly can't adjust angle; 2, then need to reset once more compensator during again with this angular adjustment when needs, process is very loaded down with trivial details, and cost of idleness; Fixing compensator is set technically then than at the straight tube place difficulty, meticulous being set, waste of manpower greatly and material resources at the turning.Whether there are a kind of indexing arbitrarily and compensator with low cost to yet there are no report.
Summary of the invention:
Goal of the invention: the purpose of this utility model has been to solve the problem that has certain difficulty when corrugated expansion joint is provided with at the turning in the past technically and has been provided with the difficult problem of adjusting angle of bend pipe of compensator.
Technological scheme: the utility model is achieved through the following technical solutions:
The universal compensator of the non-maintaining ball formula of a kind of direct-burried comprises front tube and rear end pipe, and it is characterized in that: the end points of rear end pipe is connected with shell; Be provided with spheroid in the shell, spheroid is connected with the end points of front tube; Spheroid inside is communicated with for hollow structure makes front tube and rear end pipe; Between the outer wall of spheroid and the inwall of shell for being tightly connected in relative rotation.
Shell is divided into fixed end and opening end, and fixed end is connected with rear end pipe; Be provided with baffle ring in the enclosure, the part of spheroid is passed baffle ring, and is blocked by the baffle ring activity; Be provided with rubber seal between the opening end of shell and the spheroid, rubber seal compresses by gland, and gland is fixed on the shell.
Baffle ring outward a side of shell opener end also be provided with interior rubber seal, interior rubber seal is compressed by spheroid.
Advantage and effect: the utility model provides the non-maintaining ball formula of a kind of direct-burried universal compensator, it is by being arranged on the shell and the spheroid that is arranged on the front tube on the rear end pipe, front tube and rear end pipe are communicated with, and the spheroid setting can be done with shell in the enclosure and relatively rotate, adjustable angle is whole, need not to reset fixing compensator to the same in the past according to angle; The universal compensator structure of the non-maintaining ball formula of this direct-burried is succinctly reasonable, practical, and Maintenance free uses manpower and material resources sparingly greatly.
Description of drawings:
Fig. 1 is the utility model sectional structure schematic representation.
Embodiment:
Below in conjunction with accompanying drawing the utility model is done nearly step explanation:
As shown in Figure 1, the universal compensator of the non-maintaining ball formula of a kind of direct-burried, the universal compensator of the non-maintaining ball formula of this direct-burried connects shell 4 at the end points of rear end pipe 2; End points in front tube 1 connects spheroid 3, and spheroid 3 is arranged in the shell 4, and spheroid 3 can relatively rotate with shell 4 and sealing mutually, and angle is ± 15 degree in relative rotation; Spheroid 3 inside keep being communicated with for thereby hollow structure makes front tube 1 and rear end pipe 2; Shell 4 is divided into fixed end and opening end, and fixed end is connected with rear end pipe 2; Be provided with baffle ring 7 in shell 4, the part of spheroid 3 is passed baffle ring 7, and is blocked by baffle ring 7 activities; Be provided with rubber seal 6 between the opening end of shell 4 and the spheroid 3, rubber seal 6 compresses by gland 5, realizes the sealing between spheroid 3 and the shell 4; Gland 5 is fixed on the shell 4, and the gap that forms between the opening end inwall of the outer wall of spheroid 3 and shell 4 is inwardly shunk gradually by opening, so as long as inwardly press rubber seal 6 that seal ring 6 is compressed, make sealing effect better.
And in order better to guarantee the effect of sealing, rubber seal 8 in the gap of baffle ring 7 between the inwall of the outer wall of a side, baffle ring 7 and the spheroid 3 of shell 4 opening ends and shell 4 also is provided with, interior rubber seal 8 is just in time compressed by spheroid 3.
The universal compensator of the non-maintaining ball formula of this direct-burried in use makes front tube 1 and rear end pipe 2 angled if desired, then only needs can easily realize by the rotation between spheroid 3 and the shell 4; The universal compensator of the non-maintaining ball formula of this direct-burried need not to reset fixing compensator to the same in the past according to angle, and simple for structure reasonable, practical, and Maintenance free uses manpower and material resources sparingly greatly.This structure also makes its utmost point be beneficial on a large scale and promotes.
