Abstract
The utility model discloses a pipeline connecting flange, and belongs to the field of pipeline connection. The pipeline connecting flange comprises a frustum, wherein one end of the frustum is connected onto the center of a flange plate, a round tube is arranged at the other end of the flange plate, and a plurality of guide ports are uniformly formed in the periphery of the round tube in the axial direction. According to the pipeline connecting flange, the round tube provided with the guide ports is arranged on the frustum, so that the positions of the guide ports can be inwards retracted during pipeline connection, the mounting is more convenient, and the coaxiality is higher; and simultaneously, the airtightness between a pipeline and the pipeline connecting flange is guaranteed, the service life of a conveying pipeline is prolonged, and the pipeline connecting flange is used for pipeline connection.
Description
Technical field
The utility model relates to a kind of assembling pipe joint, particularly a kind of pipeline coupling flange.
Background technique
In prior art, powder, particulate matter and fluid class material are when carrying out the pipeline conveying, pipeline was connected by the flange with frustum with being connected generally of pipeline, its deficiency is, the flange connection coaxiality is not high, thereby easily affect the sealing of pipeline and flange, and the occasion of having relatively high expectations for coaxality, easily affect life-span of pipeline, can not be suitable for.
The model utility content
The purpose of this utility model is to provide a kind of pipeline coupling flange, and its coaxality is high, easy for installation, extends the working life of pipeline.
The purpose of this utility model is achieved in that a kind of pipeline coupling flange, comprises that an end is connected to the frustum at flange plate center, and the other end of described frustum is provided with pipe, and described pipe periphery axially evenly offers a plurality of targeting ports along it.
Compared with prior art, the beneficial effects of the utility model are, the utility model by arranging a pipe with targeting port on frustum, make the utility model when connecting tube, the targeting port place can inwardly shrink, easier for installation, and coaxality is more increased, also guaranteed the sealing between pipeline and the utility model, extended the working life of conveyance conduit simultaneously.The utility model can be used in the pipeline connection.
In order further to strengthen the intensity of pipe in the utility model, the 1/2-1/3 that the degree of depth of described targeting port is pipe length doubly.Avoid pipe cross deeply easily fracture and cross shallow being not easy because of the targeting port degree of depth and shrink because of the targeting port degree of depth, thus the coaxality while affecting the utility model installation.
Coaxality when further guaranteeing that the utility model is installed, described targeting port is provided with four.Make the contraction of pipe more even.
The accompanying drawing explanation
Fig. 1 is the utility model structural representation.
The right elevation that Fig. 2 is Fig. 1.
Wherein, 1 flange plate, 2 frustums, 3 pipes, 3a targeting port.
Embodiment
A kind of pipeline coupling flange as shown in Figure 1-2, comprise that an end is connected to the frustum 2 at flange plate 1 center, the other end of frustum 2 is provided with pipe 3, pipe 3 peripheries axially evenly offer a plurality of targeting port 3a along it, doubly, targeting port 3a is provided with four to the 1/2-1/3 that the degree of depth of targeting port 3a is pipe 3 length.
During the utility model work, by the end at frustum 2, one pipe with targeting port 3a 3 is set, while making the utility model be that pipeline connects, pipe 3 can extend into pipe interior, when extruding occurs and contacts in pipe 3 and inner-walls of duct, pipe 3 can be shunk, and has guaranteed the coaxality of the utility model and pipeline, and installation and repairing is convenient.
The utility model is not limited to above-described embodiment; on the basis of the disclosed technological scheme of the utility model; those skilled in the art is according to disclosed technology contents; do not need performing creative labour just can make some replacements and distortion to some technical characteristicss wherein, these replacements and distortion are all in protection domain of the present utility model.
Claims (3)
1. a pipeline coupling flange, comprise that an end is connected to the frustum at flange plate center, it is characterized in that, the other end of described frustum is provided with pipe, and described pipe periphery axially evenly offers a plurality of targeting ports along it.
2. a kind of pipeline coupling flange according to claim 1, is characterized in that, the 1/2-1/3 that the degree of depth of described targeting port is pipe length doubly.
