Abstract
The utility model relates to a pipeline connection technology field, the utility model discloses a pipeline chucking formula connecting device, a fixed connection that is used for two compound pipe end portions, this connecting device is including first flange and the second flange of locating two compound pipe end portions respectively, locate the ring groove on the first flange lateral surface, locate the annular seal spare in the ring groove, and locate the annular bulge on the second flange lateral surface, this annular bulge cooperatees with ring groove and this annular bulge's tip extrudees on annular seal spare, this annular bulge's internal diameter is greater than compound bore of pipe, two compound pipes are connected through first flange and second flange closure. The utility model overcomes current compound union coupling department causes the problem of harm owing to be in high -pressure state.
Description
Technical field
The utility model relates to technical field of pipeline connection, in particular, and particularly a kind of pipeline clamping type connection set.
Background technique
Prior art many by flange be fixedly connected with mode by the composite pipe of some sections connect be a complete pipeline.Composite pipe is the pressure of (as blow-off line) its joint and other position consistency in use, and are less than other positions due to the withstand voltage properties of composite pipe joint, and joint so just certainly will be caused to be in high pressure conditions for a long time and to suffer damage.Therefore, be necessary to improve the structure of existing connection set.
Model utility content
The purpose of this utility model is to provide a kind of pipeline clamping type connection set, the problem such as to cause damage owing to being in high pressure conditions to overcome existing composite pipe joint.
In order to solve problem set forth above, the technical solution adopted in the utility model is: a kind of pipeline clamping type connection set, for being fixedly connected with of two composite pipe ends, this connection set comprises the first flange and the second flange of being located at two composite pipe ends respectively, be located at the annular recess on the first flange outer side surface, be located at the annular seal in annular recess, and the annular projection be located on the second flange outer side surface, this annular projection matches with annular recess and the end of this annular projection is squeezed on annular seal, the internal diameter of this annular projection is greater than the internal diameter of composite pipe, two composite pipes are by the first flange and the sealed connection of the second flange.
According to a preferred embodiment of the present utility model: described composite pipe is SRPE or steel wire mesh frame plastic composite tube.
According to a preferred embodiment of the present utility model: by the sealed connection of multiple bolt connection piece between described first flange and the second flange.
According to a preferred embodiment of the present utility model: described first flange and the second flange are welded in the end of two composite pipes respectively.
Compared with prior art, the beneficial effects of the utility model are: the structure that the employing annular projection of connection set of the present utility model and annular recess match, and the internal diameter of annular projection is arranged the internal diameter being greater than composite pipe, reduced at the pressure of its unit area of position of joint like this, avoided the infringement of pipeline junction.Meanwhile, annular seal greatly improves the sealability at position, joint.In addition, the component such as flange, Sealing can be separated when transporting and store in a warehouse, and is conducive to the stacking of each parts, decrease and take up room, make the more of the composite pipe that can hold in the space of per unit volume, be both conducive to the protection of each parts, turn improve the utilization ratio in space; In addition, connection set structure of the present utility model is simple, easily produces.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the structural representation of pipeline clamping type connection set described in the utility model.
Description of reference numerals: 1, composite pipe, the 2, first flange, the 3, second flange, 4, bolt connection piece, 5, annular projection, 6, annular recess, 7, annular seal.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, to make advantage of the present utility model and feature can be easier to be readily appreciated by one skilled in the art, thus more explicit defining is made to protection domain of the present utility model.
Consult shown in Fig. 1, the utility model provides a kind of pipeline clamping type connection set, for being fixedly connected with of two composite pipe 1 ends, this connection set comprises the first flange 2 and the second flange 3 being located at two composite pipe 1 ends respectively, be located at the annular recess 6 on the first flange 2 outer side surface, be located at the annular seal 7 in annular recess 6, and the annular projection 5 be located on the second flange 3 outer side surface, this annular projection 5 matches with annular recess 6 and the end of this annular projection 5 is squeezed on annular seal 7, and the internal diameter of this annular projection 5 is greater than the internal diameter of composite pipe 1; Two composite pipes 1 are by the first flange 2 and the sealed connection of the second flange 3.
Composite pipe 1 in the present embodiment is preferably SRPE or steel wire mesh frame plastic (PE) composite pipe.
The first flange 2 in the present embodiment and between the second flange 3 by the sealed connection of multiple bolt connection pieces 4.Adopt the connection of multiple bolt connection piece 4, both can improve intensity and the sealability of connection, can prevent from again rotating between the first flange 2 and the second flange 3.
The first flange 2 in the present embodiment and the second flange 3 preferably adopt the method for welding to be connected to the end of two composite pipes 1.
The structure that the employing annular projection 5 of connection set of the present utility model and annular recess 6 match, and the internal diameter of annular projection 5 is arranged the internal diameter being greater than composite pipe 1, reduced at the pressure of its unit area of position of joint like this, avoided the infringement of high pressure to pipeline junction.Meanwhile, annular seal 7 greatly improves the sealability at position, joint.In addition, the component such as flange, Sealing can be separated when transporting and store in a warehouse, and is conducive to the stacking of each parts; decrease and take up room; make the more of the composite pipe that can hold in the space of per unit volume, be both conducive to the protection of each parts, turn improve the utilization ratio in space.In addition, connection set structure of the present utility model is simple, easily produces.
Above-described embodiment is the utility model preferably mode of execution; but mode of execution of the present utility model is not restricted to the described embodiments; change, the modification done under other any does not deviate from Spirit Essence of the present utility model and principle, substitute, combine, simplify; all should be the substitute mode of equivalence, be included within protection domain of the present utility model.
