Abstract

The utility model discloses a pipeline structure is connected to leak protection type, including the water pipe head, the water pipe locating hole internal fixation cover of water pipe head is equipped with metal embedding pipe, metal embedding inside pipe wall is opened threadedly, and its key lies in: the water pipe locating hole is the shoulder hole, and this shoulder hole aperture internal diameter is less than metal embedding internal diameter of pipe forms seal step, is provided with the sealing washer on this shoulder hole macropore inner wall, the outer wall butt of metal embedding pipe is in on the inner wall of sealing washer, external union coupling end is provided with the external screw thread, this external screw thread with the internal thread of metal embedding pipe matches each other, will outer takeover is twisted into, and the metal imbeds intraductally. Beneficial effect: through set up the sealing washer on the macroporous inner wall of shoulder hole, prevent that water from the play of metal embedding outside of tubes wall flow, has simple structure, the leakproofness is good, and advantages such as convenient, easy repair are dismantled in waterproof leak protection.

Description

Anti-leakage type connecting pipeline structure
Technical field
This utility model belongs to connecting pipeline structure technical field, specifically, relates to a kind of Anti-leakage type connecting pipeline structure.
Background technology
Melted for connecting portion rear high temperature bond is typically formed or is formed by connecting by threaded engagement by heat melting device by the connection of water pipe and water pipe head, but, the water pipe connected by heat melting device, if installing bad being susceptible to connect blow-by and leak, and the water pipe connected by this kind of mode being difficult to laid-up;The water pipe connected by threaded engagement, its poor sealing, the water capacity is easily from joint leadkage.
Prior art shortcoming: water pipe is bad with the connection sealing of water pipe head, there is leakage inconvenience laid-up in the water pipe connected by heat melting device;The water pipe joined by screw thread and connect, water is easily from joint leadkage, and when there are vibrations, pipeline junction easily loosens, poor seismic behavior.
Utility model content
For solving above technical problem, the purpose of this utility model is to provide a kind of water pipe head sealing height, anti-seismic performance is good, mount and dismount convenient Anti-leakage type connecting pipeline structure.Concrete technical scheme is as follows:
A kind of Anti-leakage type connecting pipeline structure, including water pipe head, in the hole, water pipe location of described water pipe head, fixed cover is provided with metal and embeds pipe, described metal embeds inside pipe wall and has screw thread, it it is critical only that: hole, described water pipe location is shoulder hole, and this shoulder hole hole diameter embeds bore less than described metal, forms sealed step, being provided with sealing ring on this shoulder hole macropore inwall, described metal embeds the outer wall of pipe and is connected on the inwall of described sealing ring;Described extension tube attached connects end and is provided with external screw thread, and the female thread that this external screw thread embeds pipe with described metal is mutually matched, and described extension tube attached is screwed into metal and embeds in pipe.
Using said structure, on the basis of water pipe is by thread seal, metal embeds the outer wall of pipe and is close to sealing ring, improves the sealing that extension tube attached is connected with water pipe head, too increases metal simultaneously and embeds the anti-seismic performance between pipe and described water pipe head.
Wherein, offering cannelure on described shoulder hole macropore inwall, described sealing ring is embedded on described cannelure.So design, facilitates pipeline to dismantle.
Further, described metal is provided with sealing gasket in embedding pipe, and described sealing gasket is positioned in described sealed step.So design, when external pipeline relies on its external screw thread to be screwed in described metal embedding pipe, lucky external pipe stretches into termination and is connected on described sealing gasket, is further ensured that the sealing of water pipe head.
Further, described sealing gasket is food stage sealing gasket, and described sealing ring is food stage sealing ring, uses said structure, food stage sealing gasket good seal performance, does not produce harmful substance.
The advantages such as beneficial effect: by arranging sealing ring on the inwall of shoulder hole macropore, prevents water from embedding pipe outer wall from metal and flow out, have a simple in construction, good airproof performance, waterproof leakproof, convenient disassembly, easy repairing.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings:
A kind of Anti-leakage type connecting pipeline structure as shown in Figure 1, including water pipe head 1, in the hole 2, water pipe location of described water pipe head 1, fixed cover is provided with metal and embeds pipe 3, described metal embeds pipe 3 inwall and has screw thread, it it is critical only that: hole, described water pipe location 2 is shoulder hole, and this shoulder hole hole diameter embeds pipe 3 internal diameter less than described metal, forms sealed step 4, being provided with sealing ring 6 on this shoulder hole macropore inwall, described metal embeds the outer wall of pipe 3 and is connected on the inwall of described sealing ring 6;Described extension tube attached 8 connects end and is provided with external screw thread, and the female thread that this external screw thread embeds pipe 3 with described metal is mutually matched, and described extension tube attached 8 is screwed into metal and embeds in pipe 3.
Using said structure, on the basis of water pipe is by thread seal, metal embeds the outer wall of pipe 3 and is close to sealing ring 6, improves the sealing that water pipe is connected with water pipe head 1, too increases metal simultaneously and embeds the anti-seismic performance between pipe 3 and described water pipe head 1.
In the present embodiment, installing described sealing ring 6 by offering cannelure 7 on described shoulder hole macropore inwall, described sealing ring 6 is embedded on described cannelure 7.So design, facilitates pipeline to dismantle.
By Fig. 1 it is also seen that described metal is provided with sealing gasket 5 in embedding pipe 3, described sealing gasket 5 is positioned in described sealed step 4.So design, when external pipeline relies on its external screw thread to be screwed in described metal embedding pipe 3, lucky external pipe stretches into termination and is connected on described sealing gasket 5, is further ensured that the sealing of water pipe head 1.
In the present embodiment, described sealing gasket 5 is food stage sealing gasket, and described sealing ring 6 is food stage sealing ring, uses said structure, food stage sealing gasket good seal performance, does not produce harmful substance.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all any amendment, equivalent and improvement etc. made within spirit of the present utility model and principle, within should be included in protection domain of the present utility model.
