Abstract
The utility model discloses a manhole structure of a tank body of a filter. The manhole structure of the tank body of the filter comprises the tank body, a manhole cover and a clamping plate. The top end of the tank body is provided with a mounting hole, the manhole cover is placed on the inner side of a mounting hole, the clamping plate is placed on the outer side of the mounting hole, the manhole cover and the clamping plate are connected through a bolt, and a tank body wall on the edge of the mounting hole is clamped between the clamping plate and the manhole cover. Intensity of connection of the manhole structure and the tank body is high, the sealing effect is good, mounting is convenient, and due to the fact that the manhole structure is not directly assembled with the mounting hole at the top end of the tank body, the requirement of size accuracy of the mounting hole at the top of the tank body is low.
Description
Technical field
The utility model relates to a kind of manhole, is specifically related to a kind of manhole structure of filter tank body.
Background technology
On the top of filter tank body, manhole is installed usually, so that reinforced and maintenance.The filter tank body manhole structure of present stage, normally the top of tank body offers installing hole now, in installing hole, be embedded with the manhole inserts, at the manhole inserts manhole cover is installed, the final manhole structure who forms tank body, generally, because filter tank body inwall bears larger operating pressure, the problem that leaks air in the junction of manhole inserts and tank wall; Because the manhole inserts normally adopts different materials with tank wall, therefore, its two poor compatibility owing to material, the adhesive force of its combination is lower; And because the periphery of manhole inserts need to be directly equipped with installing hole, higher to the required precision of installing hole.
The utility model content
For the deficiencies in the prior art, the purpose of this utility model is intended to provide a kind of manhole structure of filter tank body, and itself and tank wall have higher bonding strength, guarantees that the junction has preferably sealing.
For achieving the above object, the utility model adopts following technical scheme:
The manhole structure of filter tank body, comprise tank body, manhole cover, clamping plate, the top of tank body offers an installing hole, manhole cover is positioned at the inboard of installing hole, clamping plate are positioned at the outside of installing hole, manhole cover and clamping plate are bolted, and the tank wall at installing hole edge is folded between clamping plate and the manhole cover.
Manhole cover comprises the arc main body of an epirelief, and the straight extension that is positioned at the arc body rim, and the edge of clamping plate has a straight bending edges, and the tank wall at installing hole edge is pressed between straight extension and the bending edges.
The manhole cover upper surface is protruding with a bolt mount pad, and the bottom cross-under of bolt is on the bolt mount pad.
Be provided with an O RunddichtringO between the tank wall at manhole cover edge upper surface and installing hole edge.
The beneficial effects of the utility model are:
The bonding strength of manhole structure of the present utility model and tank body is higher, good sealing effect; Easy for installation, owing to be not directly equipped with the installing hole on tank body top, lower to the dimension precision requirement of top installing hole.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the A place zoomed-in view of Fig. 1;
Fig. 3 is scheme of installation of the present utility model.
The specific embodiment
Below, by reference to the accompanying drawings and the specific embodiment, the utility model is described further:
Such as Fig. 1,2, shown in 3, manhole structure for the utility model filter tank body, it comprises tank body 1, manhole cover 2, clamping plate 3, the top of tank body 1 offers an installing hole 11, manhole cover 2 is positioned at the inboard of installing hole 11, clamping plate 3 are positioned at the outside of installing hole 11, manhole cover 2 is connected with clamping plate by bolt 4 connections, nut 5 is enclosed within the upper top of bolt 4 and is positioned at the upper surface top of clamping plate 3, the wall of the tank body 1 at installing hole 11 edges is folded between manhole cover 2 and the clamping plate 3, by fastening nut 5, make manhole cover 2 and clamping plate 3 clamp fully the wall of the tank body 1 at installing hole 11 edges.Between nut 5 and clamping plate 3 surfaces, also be provided with a pad 6 that is enclosed within on the bolt 4.
In order to realize clamping preferably effect, manhole cover 2 comprises the arc main body 21 of an epirelief and the straight extension 22 that is positioned at arc main body 21 edges, the edge of clamping plate 3 has a straight bending edges 31, clamp the wall of tank body 1 by straight extension 22 and bending edges 31, increase the contact area of manhole cover 2, clamping plate 3 and tank body 1 wall, thereby significantly increased the clamping force of manhole cover 2, clamping plate 3 pairs of tank body 1 walls.
For the ease of installing, have the bolt mount pad 23 of protrusion at manhole cover 2 upper surfaces, the bottom cross-under of bolt 4 is on bolt mount pad 23.
Be provided with an O RunddichtringO 7 between tank body 1 wall at the edge of manhole cover 2 (being straight extension 22) upper surface and installing hole 11 edges, by abundant fastening nut 5, can make manhole cover 2 and tank body 1 wall fully compress O RunddichtringO 7, to promote the sealing that connects.
Above-mentioned bolt 4 can be a plurality of, and these a plurality of bolts 4 evenly distribute, and thrust are applied to uniformly the periphery of installing hole 11.
For a person skilled in the art, can make other various corresponding changes and distortion according to technical scheme described above and design, and these all changes and distortion should belong within the protection domain of the utility model claim all.
