Description

Plastic inspection well
Technical field
The utility model relates to a kind of plastic inspection well.
Background technology
Existing plastic inspection well be substantially all branch pipe interface and well body divide welding fabrication or integral molded plastic shaping; The general of welding fabrication is welded when dispatching from the factory; Therefore no matter be that welding fabrication or integral molded plastic are shaping, all cannot change to inspection shaft during the actual installation of building site, but in a lot of place, due to the change of field condition, often cause the demand of the branch pipe interface size of inspection shaft to change, the caliber as arm such as to change at the situation; When running into this situation at present, accessory product can only being added adapt to, as usually increased adapter to realize, so naturally can increase product cost and artificial installation cost accordingly.In addition, the increase of joint must increase the risk occurring leaking; Further, some areas are subject to the restriction of narrow space, may cannot increase accessory at all and install, whole inspection shaft can only be changed completely.
Utility model content
The technical problem that the utility model solves is to provide one can adapt to various branch diameter, is convenient for changing again the plastic inspection well of branch pipe connection simultaneously.
The utility model solves the technical scheme that its technical problem adopts: plastic inspection well, the seal washer comprising main part, branch pipe connection and be arranged between main part and branch pipe connection, main part comprises at least one connector, the connector of main part is provided with main flange; One end of branch pipe connection is provided with a pipe flange, the other end is arm link, and propping up on branch pipe connection is reducing changeover portion between pipe flange and arm link; Described main part and branch pipe connection are by main flange and a pipe flange Flange joint.
Further: described reducing changeover portion is tapered.
Further: described reducing changeover portion is greater than the diameter connecting side at arm at the diameter of a pipe flange side.
Further: each main flange is connected by equally distributed eight bolts with a pipe flange.
The beneficial effects of the utility model are: by Flange joint, facilitate the dismounting between main part and branch pipe connection, improve dismounting efficiency; Also can select the arm tieing corresponding with different tube diameters according to demand simultaneously.The branch pipe connection of different size is according to the adaptation of difference realization to the arm of different tube diameters of its reducing changeover portion; Only need the branch pipe connection selecting phase factor when making to be connected with the arm of different tube diameters, do not need integral replacing inspection shaft; Effectively reduce product cost and installation cost.
Accompanying drawing explanation
Fig. 1 is the measurements of the chest, waist and hips schematic diagram of plastic inspection well described in the utility model, wherein main part has four connectors;
Fig. 2 is the front view of plastic inspection well described in the utility model, wherein main part has a connector;
Fig. 3 is the measurements of the chest, waist and hips schematic diagram of Fig. 2, and can be connected with multiple branch pipe connection adaptation;
Be labeled as in figure: main part 1, branch pipe connection 2, seal washer 3, connector 4, main flange 5, pipe flange 6, arm link 7, reducing changeover portion 8, bolt 9.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is further illustrated.
As shown in Figure 1 to Figure 3, plastic inspection well described in the utility model, the seal washer 3 comprising main part 1, branch pipe connection 2 and be arranged between main part 1 and branch pipe connection 2, main part 1 comprises at least one connector 4, the connector 4 of main part 1 is provided with main flange 5; One end of branch pipe connection 2 is provided with a pipe flange 6, the other end is arm link 7, and propping up on branch pipe connection 2 is reducing changeover portion 8 between pipe flange 6 and arm link 7; Described main part 1 and branch pipe connection 2 are by main flange 5 and pipe flange 6 Flange joint.
Wherein connector 4 is communicated with the interface between main part 1 and arm, and can arrange multiple connector 4 in theory in main part 1, as being provided with four connectors 4 in Fig. 1, and four connectors 4 are distributed on the four direction of main part 1 surrounding; Certainly, also as shown in Figures 2 and 3, a connector 4 can be only set.
Main flange 5 is arranged on connector 4, and is integrated injection mo(u)lding with main part 1, and its effect is convenient and carries out Flange joint between branch pipe connection 2.Pipe flange 6 nature in like manner on branch pipe connection 2 should match with main flange 5.
Branch pipe connection 2 realizes the connector between inspection shaft main part 1 and arm, one end of its pipe flange 6 and main part 1 Flange joint of inspection shaft; The arm link 7 of the other end is connected with arm, and usually connected mode for be threaded or interference fit connects or bonding.
In addition, inspection shaft described in the utility model, when the arm of corresponding different tube diameters, without the need to changing the main part 1 of inspection shaft, and only needs the branch pipe connection 2 changing different size.Branch pipe connection 2 be then by one section of reducing changeover portion 8 can realize to caliber change transition, the size of the pipe flange 6 on the branch pipe connection 2 of i.e. all size is identical, but by after reducing changeover portion 8, arm link 7 can form the specification of different size, to be connected with the arm of different tube diameters respectively.As shown in Figure 3, the branch pipe connection 2 of existing three kinds of different sizes, but pipe flange 6 size of three kinds of branch pipe connections 2 is identical, all can be connected with main flange 6, after by different reducing changeover portions 8, the size of its arm link 7 is then different, therefore can be connected with the arm of different tube diameters.Only need when actual installation like this to select the branch pipe connection 2 corresponding with actual branch diameter; Without the need to changing inspection shaft entirety, very convenient.
In addition, consider branch pipe connection 2 normally tubular structure, therefore the preferred tapered structure of reducing changeover portion 8.Further, also can be arranged to reducing changeover portion 8 and be greater than diameter in arm link 7 side at the diameter of pipe flange 6 side.
As for the diameter of arm link 7 side, generally can determine according to the branch diameter size that may need in reality to connect; Therefore, in theory, when having N kind branch diameter, the arm link 7 that should have N kind diameter at least of phase factor, also just has the branch pipe connection 2 that N kind is corresponding naturally at least.
In addition, in the main part 1 of inspection shaft, be provided with unnecessary connector 4, not only this connector 4 but also do not need to be connected with arm when reality uses, then can by arranging plug by its shutoff.Certainly, plug should be provided with the flange arrangement of phase factor, to be connected with the main flange 5 on connector 4.
In addition, consider tight type and the symmetry of connection, main flange 5 is preferably connected by equally distributed eight bolts 9 with a pipe flange 6 by the utility model.
To sum up, plastic inspection well described in the utility model, its structure is simple, and easy construction is good to the suitability of the arm of different tube diameters.Effective raising installation effectiveness, can reduce product cost and installation cost.
