Abstract
The utility model relates to a flexible connecting device for plain-end tube, in particular to the tubes of pollution discharge and cast iron of buildings and architectures. The two ends of the rubber sealing ring is sheathed in the flat heads of the two cast iron tubes; the outside of the two ends of the rubber sealing ring are hooped firmly with a pair of hoops by screw bolts to make the two cast iron tubes do flexible continue. The flexible connecting device for plain-end tube does not need to process the end the of tube to the base flange structure. The utility model has the advantages of easy fabrication, low cost, little space occupation, low material consumption and convenient installation and maintenance for no use of the base flange structure on the end of the tube.
Description
The utility model relates to the flexible joint device of tack pipe (promptly not with base), is specially adapted to the flexible joint device of building water drain system tack cast iron pipe.
Before the utility model piecing devices were made, the connection of building water drain system cast iron pipe was such: from Fig. 1, an end of cast iron tube is cast into has the base flange arrangement, the other end is flat-head shape (promptly not being with base).The flange base has recess part, by the tack reeve of another cast iron tube.At tack cast tube external diameter one rubber seal is arranged, be positioned at base flange-interface place, push down seal ring, two cast iron tubes are flexibly connected by gland.It is the base flange arrangement that this piecing devices part that still has some deficits, tubing must be processed (casting and cutting) Cheng Yiduan, consumes material more, increases manufacture cost; Because the base structure is arranged, take up space, seem little convenient in narrow local connection.
The purpose of this utility model is to overcome above-mentioned deficiency and a kind of tack pipe flexible joint device is provided, and tubing need not be processed into band base structure, and the tack of two cast iron tubes can flexibly connect by piecing devices of the present invention.
The description of tack pipe flexible joint device of the present utility model is as follows: the utility model piecing devices are made up of cast iron tube tack, rubber seal, anchor ear, the internal diameter of rubber seal is bigger slightly than the external diameter of connected two cast iron pipes, connected two cast iron pipes are inserted in from the two ends of rubber seal, are separated by the limited ring of rubber seal internal diameter central authorities; In the outside of rubber seal with anchor ear by bolt with two tack pipe bandings, so two tack cast iron pipes just flexibly connect.The flexibility, the sealability that connect for increasing respectively have the seal ring of 4～6 road projections on the internal diameter of rubber seal and external diameter.
Be further elaborated below in conjunction with drawings and Examples.
Description of drawings:
Fig. 1 is the flexible joint device sectional view of the cast iron pipe of prior art band base flange.
Fig. 2 is a tack pipe flexible joint device half sectional view of the present invention, among the figure 1.4-tack pipe, 2-rubber seal, 3-anchor ear.
Fig. 3 is rubber seal (a 2) half sectional view, 5-limited ring wherein, 6-seal ring.
To connect internal diameter is that the flexible joint device of two cast iron pipes of 100 millimeters is an example, and the internal diameter of cast iron pipe is 100 millimeters, and external diameter is 112 millimeters.Rubber seal (2) is made with neoprene, and its internal diameter is 114 millimeters, and width is 54 millimeters, and thickness is 3 millimeters.In the internal diameter central authorities of rubber seal (2) limited ring (5) of one projection is arranged, the limited ring width is 5 millimeters, and internal diameter is 102 millimeters.Be inserted in from the two ends of rubber seal (2) tack of two cast iron pipes (1) and (4), is separated by the limited ring of rubber seal (2) internal diameter central authorities.The flexibility and the sealability that connect for increasing respectively have the seal ring (6) of 4 road projections on the internal diameter of rubber seal (2) and external diameter.The width of seal ring (6) is 3 millimeters, 2 millimeters of projections.In the outside of rubber seal (2) an involutory anchor ear (3) is housed.The width of anchor ear is consistent with rubber seal, is 54 millimeters.Two bolts hole are arranged on the involutory anchor ear (3), two tack cast iron pipes are flexibly connected by bolt.Anchor ear (3) is made with spheroidal graphite cast iron.
The advantage of flexible connecting device for plain-end tube of the present utility model: two cast iron pipes that are connected be need not to be processed into the base flange arrangement, as long as the tack of two cast iron pipes is inserted in the two ends of the rubber seal of apparatus of the present invention, added the anchor ear banding just, thereby seeming simple, cost is lower; Because apparatus of the present invention do not have the base flange arrangement, occupy The space is little, installs in narrow or moist place. Especially fast box lunch seems; In the time of when maintenance, need inserting a joint or a few joint cast iron pipe, use flexible joint device of the present invention. Also more convenient and reliable than originally.
Claims (3)
1, a kind of pipe flexible joint device, be specially adapted to the flexible joint device of building constructions blowdown cast iron pipe, the mouth of pipe that it is characterized in that connected two pipes is the tack that does not have base, tack pipe (1) and (4) are enclosed within the inboard two ends of rubber seal (2), are separated by the limited ring (5) of rubber seal internal diameter central authorities; In the outside of rubber seal (2) with anchor ear (3) by bolt with two tack pipe bandings.
2, pipe flexible joint device according to claim 1 is characterized in that rubber seal (2) makes the seal ring (6) that 4～6 road projections is respectively arranged in the inboard and the outside of rubber seal with polychloroprene material.
