Background technique
High temperature bond after connection part melting is generally formed or is formed by connecting by screw-thread fit by heat melting device by the connection between water pipe and water pipe, but, by the water pipe that heat melting device connects, with great difficulty do not occur connect blow-by and leak if installed, and by water pipe not easily laid-up that this kind of mode connects; By the pipe connecting structure of water that screw-thread fit connects, need to use metal to embed pipe, but existing metal embedding composite pipe tightness is bad, the water capacity is easily from joint leadkage.
Prior art shortcoming: joint poor sealing between water pipe and water pipe, the water pipe connected by heat melting device occurs leaking inconvenient laid-up; Use metal to embed the water pipe of pipe connection, water is easily from joint leadkage, and the impact that joint is easily rocked occurs to loosen, poor seismic behavior.
Summary of the invention
For solving above technical problem, the object of the present invention is to provide a kind of sealing high, mount and dismount sealed type pipeline linked system easily.Concrete technological scheme is as follows:
A kind of sealed type pipeline linked system, its key is: comprise water pipe female joint and water pipe tool joint pin, the water pipe positioning hole internal fixtion of described water pipe female joint is arranged with metal and embeds pipe, the inwall of described metal embedding pipe is provided with internal thread, described water pipe tool joint pin outer wall is provided with the outside thread embedding pipe internal thread with metal and match, described water pipe positioning hole is shoulder hole, this shoulder hole hole diameter is less than described metal and embeds bore, form sealed step, embed pipe upper end-hole inwall at described metal and be provided with seal ring, described seal ring upper-end inner diameter equals the internal diameter of described internal thread, described seal ring bottom diameter is less than the internal diameter of described internal thread, described seal ring internal diameter is bottom-up to be seamlessly transitted.
Described metal embeds pipe outer wall and to be sticked seal ring, and described seal ring upper end external diameter is greater than the external diameter that described metal embeds pipe, and described seal ring lower end external diameter equals the external diameter that described metal embeds pipe, and described seal ring external diameter seamlessly transits from top to bottom.
Described metal embeds infratubal port inwall and is provided with circular groove, sealing gasket is embedded with in described circular groove, the outer wall of described sealing gasket is connected on the sidewall of described circular groove, the internal diameter of described sealing gasket is less than the internal diameter that described metal embeds pipe, and the thickness of described sealing gasket is greater than the height of described circular groove sidewall.
Based on the sealed type pipeline linked system of said structure, in use, needing this metal to be embedded pipe inserts in water pipe female joint, sealing gasket place end is connected in the sealed step of water pipe female joint, seal ring is close to described metal and embeds on pipe, and along with metal embeds stretching into of pipe, seal ring is extruded by the inwall of water pipe female joint gradually, fill up described metal and embed the gap of managing between water pipe female joint, realize metal and embed the sealing of managing between water pipe female joint; When water pipe tool joint pin is screwed into metal embedding pipe, seal ring also can extrusion, fill up the gap between metal embedding inner tube wall and water pipe tool joint pin outer wall, until the termination of water pipe tool joint pin is connected on described sealing gasket, realize the two-stage sealing of pipeline junction.
In the specific implementation, described seal ring, seal ring and sealing gasket all adopt food-grade sealing material to make, and food-grade sealed material good seal performance, does not produce harmful matter.
Beneficial effect: structure is simple, for convenience detach; By embedding pipe upper end inwall at metal, seal ring is set, outside, upper end has been sticked seal ring, lower end inner wall arranges sealing gasket, realize metal embed pipe with pipe coupling between, metal embed pipe with water pipe tool joint pin between multi-sealed, sealing effect improves greatly, improves the anti-seismic performance that pipeline connects simultaneously.
