Abstract
The invention discloses an axial length compensation type pipe joint and relates to an axial length compensation type pipe joint for a mine drainage pipe. A small-neck straight-through pipe is arranged on the center axis of a large-neck straight-through pipe, a limiting flange with the guiding and limiting functions is arranged between the small-neck straight-through pipe and the large-neck straight-through pipe, and a sealing assembly is arranged between the small-neck straight-through pipe and the large-neck straight-through pipe. The axial length compensation type pipe joint has the advantages of being small in mounting workload, small in axial compensation error and convenient to install and use.
Description
Technical field
The present invention relates to the compensation pipe joint of a kind of waste pipe axial length, relate in particular to the axial length compensation formula of mine drainage pipe pipe joint.
Background technique
Well-known: in plumbing operation process, the waste pipe that plumbing equipment is used is after installing, length generally cannot be made and change again, but, due to the error of installing and the change of working environment, often cause the supplying drainage after installing cannot reach best length requirement, especially under coal mine in the operation process of water-pumping/draining, because waste pipe is usually in the mine wall being fixed in construction, but, according to the height that requires mine wall of construction, usually need to change, thereby, the waste pipe adhering on it generally also will correspondingly change, because existing waste pipe cannot change after fixing, so, must be from new installation, exist and use inconvenience and the defect bothering.To this, Chinese invention patent application 201110338568.0 discloses a kind of butterfly pipeline compensator, realize conduit axis after fixing apart from length compensation object, although this kind of device can be realized the object of conduit axis length compensation, but, because the variation of its axial length is to rely on resiliently deformable to realize, and elastic element is the spring that is similar to butterfly, because each elastic element axis compensation rate is very limited, so, must use the Flexible element of the spring composition of more butterfly, just can realize larger nose balance amount, cause installation workload larger, nose balance amount error is larger, still the defect that exists installation and use comparatively to bother.
Summary of the invention
The object of the invention is to: for the needs of the suitable axial direction length compensation of pipeline needs after needing in plumbing operation process to install and the existing installation workload of existing duct length compensator is large, nose balance amount error greatly, the defect that comparatively bothers of installation and use, the invention provides the compensation pipe joint of a kind of novel axial length.
The compensation pipe joint of a kind of axial length of the present invention, it is by little neck straight-through tube, blind flange, bolt, black box, positioning ring, spacing flange, large neck straight-through tube forms, it is characterized in that: one end of large neck straight-through tube is shaped with inside stepped counterbore, central axis position at large neck straight-through tube arranges a little neck straight-through tube, described little neck straight-through tube outer end has fastening flange, described little neck straight-through tube inner end arranges fixes a spacing flange, a positioning ring is set in stepped counterbore inner end, the external diameter of described positioning ring and internal diameter join with stepped counterbore inner circle and little neck straight-through tube cylindrical respectively, in stepped counterbore port position, with bolt, install and fix a blind flange, the outer neck of the endoporus of described blind flange and little neck straight-through tube joins, between blind flange and positioning ring, be provided with black box.
Beneficial effect: the present invention is because the relatively large neck straight-through tube of little neck straight-through tube has axially movable degrees of freedom, and axially movable length can easily regulate in travel range, so, when being connected between two pipelines, just can compensate easily the axial distance between pipeline, have that installation workload is less, nose balance amount error is less, an installation and use advantage comparatively easily.

Embodiment
The compensation pipe joint of a kind of axial length, it is by little neck straight-through tube (1), blind flange (2), bolt (3), black box (4), positioning ring (5), spacing flange (6), large neck straight-through tube (7) forms, it is characterized in that: the one end at large neck straight-through tube (7) is shaped with inside stepped counterbore (8), central axis position at large neck straight-through tube (7) arranges a little neck straight-through tube (1), in little neck straight-through tube (1) outer end, there is fastening flange (9), in little neck straight-through tube (1) inner end, arrange and fix a spacing flange (6), in stepped counterbore (8) inner end, a positioning ring (5) is set, the external diameter of positioning ring (5) and internal diameter join with stepped counterbore (8) inner circle and little neck straight-through tube (1) cylindrical respectively, at stepped counterbore (8) bolt for port position (3), install and fix a blind flange (2), the endoporus of blind flange (2) and the outer neck of little neck straight-through tube (1) join, between blind flange (2) and positioning ring (5), be provided with black box (8), in concrete using process, be connected between two pipelines, because the relatively large neck straight-through tube of little neck straight-through tube (1) (7) has axially movable degrees of freedom, so can realize the object of Compensation Regulation pipeline total length.
Claims (2)
1. the compensation pipe joint of waste pipe axial length, is characterized in that: it comprises that little neck straight-through tube (1), blind flange (2), bolt (3), black box (4), positioning ring (5), spacing flange (6), large neck straight-through tube (7) form.
2. according to claim 1, the compensation pipe joint of a kind of waste pipe axial length, it is characterized in that: the one end at large neck straight-through tube (7) is shaped with inside stepped counterbore (8), central axis position at large neck straight-through tube (7) arranges a little neck straight-through tube (1), in little neck straight-through tube (1) outer end, there is fastening flange (9), in little neck straight-through tube (1) inner end, arrange and fix a spacing flange (6), in stepped counterbore (8) inner end, a positioning ring (5) is set, the external diameter of positioning ring (5) and internal diameter join with stepped counterbore (8) inner circle and little neck straight-through tube (1) cylindrical respectively, at stepped counterbore (8) bolt for port position (3), install and fix a blind flange (2), the endoporus of blind flange (2) and the outer neck of little neck straight-through tube (1) join, between blind flange (2) and positioning ring (5), be provided with black box (8).
