Abstract
The utility model discloses a water piping connection seal structure, 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 sealed lateral wall butt that fills up is on the macroporous inner wall of shoulder hole, metal embedding pipe butt is in sealed stacking up, the sealed width that fills up equals seal step's width. Beneficial effect: the utility model relates to a water piping connection seal structure, simple structure, it is good to have the leakproofness, waterproof leak protection, long service life dismantles advantages such as convenient, easy repair.
Description
Technical field
This utility model belongs to pipe joint or pipe fitting technical field, specifically, relates to a kind of water pipe and connects sealing 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.
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 water pipe connection sealing structure.Concrete technical scheme is as follows:
A kind of water pipe connects sealing 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, this shoulder hole hole diameter embeds bore less than described metal, form sealed step, it is placed with sealing gasket in described sealed step, the sidewall of described sealing gasket is connected on the inwall of shoulder hole macropore, described metal embeds pipe and is connected on described sealing gasket, and the width of described sealing gasket is equal to the width of described sealed step.
Use 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, improve the sealing that water pipe is connected with water pipe head, and 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.
Further, described sealing gasket is food stage sealing gasket, uses said structure, food stage sealing gasket good seal performance, does not produce harmful substance.
Beneficial effect: this utility model is that a kind of water pipe connects sealing structure, simple in construction, has good airproof performance, waterproof leakproof, the advantages such as service life is long, 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 water pipe as shown in Figure 1 connects sealing structure, 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, described metal embeds pipe 3 and is connected on described sealing gasket 5, the width of described sealing gasket 5 is equal to the width of described sealed step 4.
Use 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, improve the sealing that water pipe is connected with water pipe head 1, and so design, when the pipeline connect relies on its external screw thread to be screwed in described metal embedding pipe 3, its inserting end termination is also connected on described sealing gasket 5 just, is further ensured that the sealing of water pipe head 1.
In the present embodiment, described sealing gasket 5 is food stage sealing gasket, uses said structure, food stage sealing gasket good seal performance, does not produce harmful substance.
