Abstract
The utility model belongs to the cast iron water discharge pipe of the building pipeline device class. A pipe joint comprises a socket and a faucet. The utility model is characterized in that the end face of the socket is provided with a socket flange; the socket flange and a movable flange which is sheathed on the faucet are connected and screwed by screw bolts; a press cover presses the sealing pipe joint of a rubber sealing ring which is arranged between the socket flange and the movable flange press cover. When the water drainage pipeline device provided with the utility model is subject to the force, the socket and the faucet of each pipe joint generate the displacement, and do not affect the sealing performance. The rubber sealing ring is not slacked and fractured caused by the long-term heat expansion and cold contraction circulation of the pipe joint.
Description
The utility model is a kind of building that is used for, and particularly high-rise building is got rid of the iron drain-pipe of the drainage pipe device of waste water, sewage, rainwater.
The cement mortar fill plug seal is used after with the cement mortar or the cotton cord that rockfills in gap between the holding of the union of the existing spigot-and-socket iron drain-pipe that is used for building drainage pipe device, socket.Its union is rigid, not antidetonation, easily split leakage, it especially not really is applicable to the drainage pipe device of installation of high-building thing.
The purpose of this utility model is to design a kind of high-rise building that can form flexible pipe joint with flexible pipe joint iron drain-pipe (comprising cast iron draining straight tube and pipe fitting, hereinafter to be referred as iron drain-pipe).To adapt to high-rise building drainage pipe device antidetonation, leakage proof, needs easy for assembly, disassembly and maintenance.When the drainage pipe device of installing with this iron drain-pipe was stressed, the holding of union between its each joint, socket can be subjected to displacement each other and do not influence its sealing; Simultaneously, the union of this iron drain-pipe duct device is destroyed its sealing because of long-term rising-heat contracting-cold circulation yet.
The purpose of this utility model is achieved in that at the end face of iron drain-pipe bellmouth makes socket flange, on the socket of iron drain-pipe, put a loose flange gland that matches with socket flange, when thisly hold with having, the iron drain-pipe of socket form installs building, particularly during the drainage pipe device of high-rise building, between the socket flange of each union and loose flange gland, be inserted in rubber seal, link with bolt then and tighten socket flange and loose flange gland.At this moment, the loose flange gland be about to that rubber seal is pressed into tightly that iron drain-pipe road union holds, the gap between socket and sealed fitting.
The rubber seal General Purpose Rubber, acid-fast alkali-proof rubber, oil resistant rubber manufacturing.
Like this, when this iron drain-pipe duct device was stressed, the holding of union, socket just can be subjected to displacement each other between its each joint.But because rubber seal has elasticity and pliability, thereby it still can be clogged that each union holds, the gap between socket and its sealing is not destroyed.The add up distortion of each union of iron drain-pipe duct device, thereby the stressed back of whole drainage pipe device deflection can be very big.Because the elasticity and the pliability of rubber seal, thereby it can loose, the fracture with the long-term rising-heat contracting-cold circulation of iron drain-pipe union.So the iron drain-pipe duct device that can form this flexible pipe joint has the advantage of antidetonation, leakage proof, and easy for assembly, disassembly and maintenance.
The concrete structure of utility model is provided by following examples and accompanying drawing thereof.
Fig. 1 is the sectional view according to the iron drain-pipe union that the utility model proposes.
Describe the structure and the working condition (other union is as the same) of a union in the drainage pipe device of installing according to this iron drain-pipe of the usefulness that the utility model proposes in detail below in conjunction with Fig. 1.
This union is made up of bellmouth (1), socket (4), loose flange gland (3) and rubber seal (6) and the connecting bolt (5) of band socket flange (2).When cylinder iron draining straight tube and pipe fitting are installed the drainage pipe device of building, particularly high-rise building, link and tighten socket flange (2) and loose flange gland (3) with bolt (5).At this moment, being clipped in therebetween the rubber seal made from General Purpose Rubber (6) is just pushed tightly and is stopped up gap between socket (4) and bellmouth (1) and sealed fitting.Because it is all gapped between socket (4) and bellmouth (1) and loose flange gland (3), and rubber seal (6) has elasticity and pliability, therefore, if this drainage pipe device is stressed, deflection not only can take place in this union, and can be subjected to displacement at direction of axis line.But at this moment rubber seal still can be clogged the gap of union and do not influenced its sealing.
Gap between the bolt hole on bolt (5) and socket flange (2) and the loose flange gland (3), not only be to be convenient to the installation of iron drain-pipe duct device, and it also is to help the distortion of this device union when the iron drain-pipe duct device is stressed.
When the drainage pipe device of installing with this iron drain-pipe was stressed, its each union can be out of shape and not influence its sealing.Rubber seal (6) can be not loose because of the long-term rising-heat contracting-cold circulation of union yet, fracture.
Claims (2)
1, a kind of building that is used for, the high-rise building of high-rise building drainage pipe device flexible pipe joint iron drain-pipe particularly, its union partly comprises bellmouth (1) and socket (4), it is characterized in that: the end face at bellmouth (1) has socket flange (2), with bolt (5) link and tighten socket flange (2) and be enclosed within on the socket (4) loose flange gland (3) pressing clip betwixt rubber seal (6) filling bellmouth (1) and the clearance seal union between socket (4).
2, iron drain-pipe according to claim 1 is characterized in that: the material of making rubber seal (6) is General Purpose Rubber, acid-fast alkali-proof rubber, oil resistant rubber.
