Abstract
The utility model discloses a leak protection pipe joint, 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, the pad is sealed to last having placed of seal step, the lateral wall butt of sealing washer is on the macroporous inner wall of shoulder hole, metal embedding pipe butt is in sealed stacking up, on the macroporous inner wall of shoulder hole, still be provided with the sealing washer, seted up the ring channel on shoulder hole macropore inner wall, the sealing washer inlays on the ring channel. Beneficial effect: simple structure, the convenient dismantlement, the outside of tubes wall sets up the sealing washer and two pipe joint set up sealed the pad through imbedding at the metal, and sealed effect improves greatly.
Description
Technical field
This utility model belongs to pipe joint structure technical field, specifically, relates to a kind of leakproof pipe joint.
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.
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, mount and dismount convenient leakproof pipe joint.Concrete technical scheme is as follows:
A kind of leakproof pipe joint, 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, and 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, form sealed step, being placed with sealing gasket in described sealed step, the sidewall of described sealing gasket is connected on the inwall of shoulder hole macropore, and described metal embeds pipe and is connected on described sealing gasket；On the inwall of described shoulder hole macropore, being additionally provided with sealing ring, offer cannelure (7) on described shoulder hole macropore inwall, described sealing ring (6) is embedded on described cannelure (7).
Using said structure, on the basis of water pipe is by thread seal, the mouth of pipe of water pipe can abut against with the sealing gasket being arranged in sealed step, improves the sealing that water pipe is connected with water pipe head；Metal embeds the outer wall of pipe and uses sealing ring to seal further, is greatly improved the sealing that water pipe connects, and by offering cannelure on shoulder hole macropore inwall, sealing ring is embedded on cannelure, and so design facilitates the dismounting of pipe joint.
Further, the width of described sealing gasket, equal to the width of described sealed step, so designs, when the pipeline connect relies on its external screw thread to be screwed in described metal embedding pipe, just also it is connected on described sealing gasket by inserting end termination, adapter road, is further ensured that the sealing of water pipe head.When sealing ring is set,
Further, described sealing gasket is food stage sealing gasket, and described sealing ring is food stage sealing ring, uses said structure, and food stage sealing ring tightness can be good, does not produce harmful substance.
Beneficial effect: simple in construction, convenient dismounting；Arranging sealing gasket by arranging at metal embedding pipe outer wall at sealing ring and pipe joint two, sealing effectiveness is greatly improved.
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 leakproof pipe joint 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, this shoulder hole hole diameter embeds pipe 3 internal diameter less than described metal, form sealed step 4, it is placed with sealing gasket 5 in described sealed step 4, the sidewall of described sealing gasket 5 is connected on the inwall of shoulder hole macropore, and described metal embeds pipe 3 and is connected on described sealing gasket 5；On the inwall of described shoulder hole macropore, it is additionally provided with sealing ring 6.
Using said structure, on the basis of water pipe is by thread seal, the mouth of pipe of water pipe can abut against with the sealing gasket 5 being arranged in sealed step 4, improves the sealing that water pipe is connected with water pipe head 1；Metal embeds the outer wall of pipe 3 and uses sealing ring 6 to seal further, is greatly improved the sealing that water pipe connects.
Be it can also be seen that by Fig. 1, the width of described sealing gasket 5 is equal to the width of described sealed step 4, so design, when the pipeline connect relies on its external screw thread to be screwed in described metal embedding pipe 3, just also it is connected on described sealing gasket 5 by inserting end termination, adapter road, is further ensured that the sealing of water pipe head 1.When arranging sealing ring, by offering cannelure 7 on described shoulder hole macropore inwall, described sealing ring 6 is embedded on described cannelure 7, and so design facilitates the dismounting of pipe joint.
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, and food stage sealing ring tightness can be good, does not produce harmful substance.
