Abstract
The utility model relates to a pipe connecting device which solves the problems of better sealing, shock resistance, convenience, etc. A flexible fastening type connecting device for a water discharge cast iron pipe, comprising an insertion opening, a faucet, a pressing flange, a rubber ring and a connecting fastener. The utility model is characterized in that the insertion opening is sheathed with the pressing flange, and the insertion opening of the inner side end of the pressing flange is sheathed with the rubber ring; the end head of the faucet is provided with a pressing flange edge which has the same and symmetrical shape as the pressing flange and is integrally connected with the pressing flange; the pressing flange and the outer edge of the pressing flange edge are sheathed with split-type hoop pressing rings. The utility model is used for connecting the pipes, such as straight pipes, three-way valves, bends, etc.
Description
The utility model relates to the cast iron pipe fittings interface, particularly a kind of cylinder iron pipe connecting device of draining that is suitable for, and it can be used for the connection of straight tube, threeway, elbow etc.
Existing draining pipe fitting, it assembles, and generally adopts filling concrete in bellmouth, is sealed, though structure is simple, construction is not saved trouble, and this structure is stiff to the size requirement of pipe fitting, poor seismic behavior, especially the dismounting maintenance is convenient inadequately, the inventor had once designed " draining of flexible combination formula is pipe connecting device cylinder iron " and had applied for having obtained Chinese patent for this reason, through practice, now this had been done further improvement
The purpose of this utility model makes improvements existing flexible cast iron pipe fittings connection set exactly, thereby a kind of better flexible hooped type water-drainage tube part connection set is provided.
The purpose of this utility model is achieved in that flexible hooped type drain cast iron pipe spare connection set, and it comprises socket, bellmouth, differential, cushion rubber and connects fastening piece; It is characterized in that: in the sheathed differential of socket, sheathed cushion rubber on differential medial extremity socket; Establish in addition in the bellmouth termination be with the differential symmetry identical shaped and with bellmouth be the differential limit of one; At differential and the sheathed opposite opened lock ring of differential limit outer rim pressure ring.
Above-mentioned design, by sheathed differential and cushion rubber on socket, and in the sheathed again lock ring pressure ring of the differential limit of differential and bellmouth outer rim; Use bolt, packing ring and nut anchor ear lock ring pressure ring then, pipe fitting socket, bellmouth are linked together firmly, reached better effect such as sealing, shock resistance, versatility, and the water-drainage tube part of all size capable of being combined requirement, and easy construction, dismounting is quick.
Below by drawings and Examples the utility model is described further again.
The three-dimensional decomposition texture schematic representation of Fig. 1 the utility model;
Fig. 2 the utility model combination sectional structure schematic representation;
Fig. 3 the utility model combination side-looking structural representation;
As shown in the figure: in socket 1 sheathed differential 2, sheathed cushion rubber 3 on differential 2 medial extremity sockets 1; Bellmouth 4 terminations establish be with differential 2 symmetry identical shaped and with bellmouth 4 be one differential limit 18; Opposite opened lock ring pressure ring at differential 2 and the sheathed band lug 19,20 of differential limit 18 outer rims, this lock ring pressure ring is made up of two half lock ring pressure rings 5,9 of symmetry, in Fig. 1, omit in addition partly for ease of expressing, and lug 19,20 is provided with screw 16 and breach 17 thereon, and it is tight to wear anchor ear with bolt 6, packing ring 7 and nut 8.Differential 2 outer rims are inclined-plane 12, and differential limit 18 outer rims are the inclined-plane 11 symmetrical with inclined-plane 12, and this inclined- plane 11,12 just be the set inclined-plane of lock ring pressure ring inner edge 14, the 15 hoop pressures of coincideing; Differential 2 and cushion rubber 3 end face in opposite directions are and the perpendicular plane 13 of socket 1 center line; Cushion rubber 3 outer rims are established inclined-plane 21, and this inclined-plane 21 just is the set inclined-plane of differential limit 18 inner edges 10 identical glands.Therefore cushion rubber 3 had both compressed socket 1, and itself is compressed by bellmouth 4 and lock ring pressure ring 5,9 again simultaneously, and the casting of this bellmouth 4 is also without difficulty, and to using great convenience, dismounting is quick.
Claims (2)
1. flexible hooped type drain cast iron pipe spare connection set, it comprises socket, bellmouth, differential, cushion rubber and connects fastening piece; It is characterized in that: in the sheathed differential of socket, sheathed cushion rubber on differential medial extremity socket; Establish in addition in the bellmouth termination be with the differential symmetry identical shaped and with bellmouth be the differential limit of one; At differential and the sheathed opposite opened lock ring of differential limit outer rim pressure ring.
2. pipe connecting device as claimed in claim 1 is characterized in that: differential and differential limit outer rim are established and are two symmetrical inclined-planes, and bind round pressure mutually for the set identical therewith inclined-plane of lock ring pressure ring inner edge; The cushion rubber outer rim is established the inclined-plane and is bound round pressure mutually for the set identical therewith inclined-plane of differential limit inner edge.
