Abstract
The utility model relates to a pipeline compensation joint which is simple and compact in structure, quick and laborsaving in adjustment, low in cost, high in corrosion resistance, high in product feeding quality and long in service life. The pipeline compensation joint comprises a telescopic pipe and a telescopic sleeve with a flange, wherein the telescopic pipe is telescopically arranged in the telescopic sleeve and provided with a flange at a free end. An annular seal ring is arranged between the telescopic sleeve and the telescopic pipe and fastened through a pressure cover with a flange, and a limiting flange seat is arranged outside the telescopic pipe and connected with the flanges on the telescopic sleeve and the pressure cover through a telescopic pull rod. The telescopic pull rod is provided with a pressure cover pressing nut and double anti-loosing limiting nuts, and an epoxy resin layer is coated on the inner side wall of the telescopic pipe.
Description
Technical field
The utility model relates to a kind of pipe joint, particularly a kind of compensation of pipeline joint.
Background technique
It is pump, valve that the compensation of pipeline joint is also named expansion joint, and the new product that equipment such as pipeline are connected with pipeline couples together them through bolt; Make it become integral body; And certain displacement amount is arranged, so just can when installation and maintenance, adjust according to on-the-spot installation dimension; When work, can pass end thrust also to whole tubing.So not only increase work efficiency, and pipe-line equipments such as pump, valves are played certain protective role.
Existing compensation of pipeline joint is generally processed by cast iron or copper material; The compensation of pipeline joint that copper material is processed contacts with liquid medium has certain decay resistance, but its cost of material is high, the compensation of pipeline joint that cast iron materials is processed; The cost of material is low, using scope is wide; But its poor corrosion resistance, the burn into that its surface of internal cavity is vulnerable to liquid medium in the using process gets rusty, and the feed-water quality of product is poor, working life short.
Summary of the invention
To the problems referred to above, the utility model propose a kind of simple and compact for structure, adjustment is laborsaving fast, cost is low, corrosion resistance and good, product feed-water quality are good, the compensation of pipeline joint of long service life.
For solving this technical problem; The utility model is taked following scheme: a kind of compensation of pipeline joint; Comprise the extension sleeve that has flange plate and telescopicly be located in the extension sleeve and its free end also is provided with the telescopic pipe of flange plate; Be provided with O-ring seal between said extension sleeve and the telescopic pipe, and tighten up through the gland that has flange plate, the outside of said telescopic pipe is provided with spacing flange seat and is connected with flange plate on extension sleeve, the gland through telescopic lever; Said flexible rod is provided with gland gland nut and the two stop nuts of spacing anticreep pine, and the madial wall of said telescopic pipe applies one deck epoxy resin layer.
Further improvedly be: be provided with hold-down bolt between said gland and the extension sleeve, said hold-down bolt is provided with and compresses the gland nut that gland is used.
Further improvedly be: said O-ring seal is a trapezium structure.
Through adopting the aforementioned techniques scheme; The beneficial effect of the utility model is: this novel compensation of pipeline joint; Inside circumference wall at telescopic pipe applies one deck epoxy resin layer, and epoxy resin layer has improved the corrosion resistance of compensating joint, has improved the feed water quality of compensation of pipeline joint; Prolonged the working life of compensation of pipeline joint, overcome existing compensating joint cavity inner surface wall and be subject to the shortcoming that the liquid medium burn into gets rusty.
Description of drawings
Fig. 1 is the utility model example structure schematic representation.
Embodiment
Combine accompanying drawing and specific embodiment that the utility model is further specified at present.
With reference to figure 1, present embodiment discloses a kind of compensation of pipeline joint, comprises the extension sleeve 1 that has flange plate 11 and telescopicly is located in the extension sleeve 1 and its free end also is provided with the telescopic pipe 2 of flange plate 21; Be provided with O-ring seal 3 between said extension sleeve 1 and the telescopic pipe 2, and tighten up through the gland 4 that has flange plate 41, the outside of said telescopic pipe 2 is provided with spacing flange seat 22 and is connected with flange plate on extension sleeve 1, the gland 4 through telescopic lever 5; Said flexible rod 5 is provided with gland gland nut 51 and the two stop nuts 52 of spacing anticreep pine; The madial wall of said telescopic pipe 2 applies one deck epoxy resin layer 23, is provided with hold-down bolt 42 between said gland 4 and the extension sleeve 1, and said hold-down bolt 42 is provided with and compresses the gland nut 43 that gland is used; Adjustment product two ends connect length during installation; The hold-down bolt of gland is evenly tightened at the diagonal angle successively, adjusts stop nut again, so just can let flexible pipeline freely stretch; The locking extending amount is guaranteed the safe operation of pipeline.
Said O-ring seal 3 is a trapezium structure, in the process that realizes sealing, can do suitable adjustment through hold-down bolt according to the difference of pressure medium, has improved its sealing effect greatly.
This novel compensation of pipeline joint; Inside circumference wall at telescopic pipe applies one deck epoxy resin layer; Epoxy resin layer has improved the corrosion resistance of compensating joint; Improved the feed water quality of compensation of pipeline joint, prolonged the working life of compensation of pipeline joint, overcome existing compensating joint cavity inner surface wall and be subject to the shortcoming that the liquid medium burn into gets rusty.
The above record is merely the embodiment who utilizes this origination techniques content, anyly is familiar with modification, the variation that this creation of this art utilization is done, and all belongs to the claim of this creation opinion, and is not limited to embodiment announcement person.
