Description
Technical field
The present invention relates to a kind of drainage pipe connector and pipe fitting joint structure, mainly apply in drainage pipeline system.
Background technique
In the pipe-line system of domestic sewage, connection, the laying of discharge pipe line are carried out often after floor agent structure construction completion.But when laying new discharge pipe line, due to size heterogeneity and the design deficiency of the unreasonable and original pipeline of floor planning, often need to destroy original building structure, but also can bring and lay the high and problem such as serious of leaking of difficulty, cost.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of drainage pipe connector and pipe fitting joint structure, this drainage pipe connector is simple and reasonable, can while not destroying building structure for the pipe fitting joint structure that formed after connecting waste pipe, construction cost can also be reduced and effectively prevent from leaking, the problem such as infiltration.
For solving the problems of the technologies described above, the present invention by the following technical solutions:
On the one hand, the invention provides a kind of drainage pipe connector.This drainage pipe connector comprises dialectal switching pipe and lower interface pipe, and dialectal switching pipe and lower interface pipe are connected with one heart for reducer pipe structure, and its improvements are: reducer pipe inside configuration is provided with snap ring, and snap ring is along the inwall circumference distribution of lower interface pipe.Snap ring then more is arranged at dialectal switching pipe and lower interface pipe joint.
General, because the waste pipe specification be connected is identical, and conveniently connect, often dialectal switching bore is all greater than the waste pipe be connected, so drainage pipe connector also needs to be configured with to be bumped into part, be bumped into the body that part is ring structure, the external diameter of body and the internal diameter of dialectal switching pipe suitable, the sidewall of body is also provided with the expansion joint disconnected by sidewall.Expansion joint is generally axial setting.
The described sidewall being bumped into part is preferably equal thickness, to reduce cost of production.More excellent, described in be bumped into part sidewall thickness be 5 ~ 10mm, the pipeline at the link place that blocks the drain after can preventing the imbibitions such as the toilet paper in waste pipe, silk fabrics under this sidewall thickness.
The described axial height being bumped into part is generally 1/4 ~ 3/4 of dialectal switching pipe axial height, to make to be reserved with certain variable space during connecting tube, simultaneously so that open side pipe to form threeway below dialectal switching pipe sidewall.
Conventional, the material of described drainage pipe connector mostly is plastic material, such as PVC, PP etc.
On the other hand, the present invention also provides a kind of pipe fitting joint structure.This pipe fitting joint structure is that above-mentioned drainage pipe connector is for connecting the concrete structure after waste pipe.Mainly in two kinds of situation:
One is the situation not needing to be bumped into part.Pipe fitting joint structure now, comprises top pipeline, below pipeline and the drainage pipe connector not with being bumped into part.The external diameter of top pipeline and below pipeline is suitable with the internal diameter of dialectal switching pipe and lower interface pipe respectively, and the lower nozzle of top pipeline and the upper orifice of below pipeline insert in dialectal switching pipe and lower interface pipe respectively.
Two is the situations needing to be bumped into part.Pipe fitting joint structure now, comprises the drainage pipe connector that top pipeline, below pipeline and band are bumped into part.The internal diameter of the below external diameter of pipeline and lower interface pipe is suitable, the external diameter of top pipeline is less than the internal diameter of dialectal switching pipe, the top lower nozzle of pipeline and the upper orifice of below pipeline insert in dialectal switching pipe and lower interface pipe respectively, and the gap between top pipeline and dialectal switching pipe is bumped into benefit in fact by being bumped into part.
In above-mentioned two situations, dialectal switching pipe can be common body, also can be three-way pipe.The radial thickness of snap ring is then preferably equal with the wall thickness of below pipeline.
Preferably, the external diameter of top pipeline is less than the internal diameter 5 ~ 10mm of dialectal switching pipe, with coordinate be bumped into part be bumped into use.The length that top pipeline inserts in dialectal switching pipe is then preferably 1/4 ~ 3/4 of dialectal switching pipe height, and now dialectal switching pipe can be three-way pipe, and the connecting port of the side pipe of three-way pipe is positioned at below the lower nozzle of top pipeline.
General, drainage pipe connector can be embedded in after on floor in advance, reconnects square tube road and below pipeline.Now, the upper end of dialectal switching pipe exposes pre-buried or concordant with pre-buried, and the lower end mouth of pipe of lower interface pipe is just to the connecting port on floor, and the upper orifice of below pipeline inserts in lower interface pipe through after connecting port.Time pre-buried, the lower end of lower interface pipe preferably arranges the base plate for fixing drainage pipe connector position.Base plate is generally tabular, and centre has the fixed hole suitable with the lower end external diameter of lower interface pipe; When base plate is set, base plate is placed on lower interface pipe outer and lie against on floor.
Beneficial effect of the present invention is:
1, drainage pipe connector is rational in infrastructure, can once-through, and applicability is wide, and good seal performance when connecting for waste pipe is easy to connect.
2, drainage pipe connector directly can be embedded in pipeline junction in advance, and after pre-buried, adapter forms pipe fitting joint structure again, easy to use, is applicable to multiple occasion.
3, do not need to destroy original building structure when pipe fitting joint structure is laid, construct convenient, construction cost is low, can effectively prevent from leaking, the problem such as infiltration.
