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 between water pipe and water pipe, 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 pipe connecting structure of water connected by threaded engagement, is needed to use metal to embed pipe, but existing metal embedding composite pipe tightness is bad, and the water capacity is easily from joint leadkage.
Prior art shortcoming: junction poor sealing between water pipe and water pipe, there is leakage inconvenience laid-up in the water pipe connected by heat melting device；Using metal to embed the water pipe that pipe connects, water is easily from joint leadkage, and junction easily is occurred to loosen by rocking to be affected, poor seismic behavior.
Utility model content
For solving above technical problem, the purpose of this utility model is to provide a kind of sealing height, mount and dismount convenient closed type connecting pipe of pipeline.Concrete technical scheme is as follows:
A kind of closed type connecting pipe of pipeline, it it is critical only that: includes water pipe female joint and water pipe male joint, in the hole, water pipe location of described water pipe female joint, fixed cover is provided with metal and embeds pipe, described metal embeds and is provided with female thread on the inwall of pipe, it is provided with on described water pipe male joint outer wall and embeds, with metal, the external screw thread that pipe female thread matches, hole, described water pipe location is shoulder hole, this shoulder hole hole diameter embeds bore less than described metal, form sealed step, embed pipe upper port inwall at described metal and be provided with sealing ring, described sealing ring upper-end inner diameter is equal to the internal diameter of described female thread, described sealing ring bottom diameter is less than the internal diameter of described female thread, described sealing ring internal diameter is bottom-up to be seamlessly transitted.
Described metal embeds pipe outer wall and has been sticked sealing ring, and described sealing ring upper end external diameter embeds the external diameter of pipe more than described metal, and described sealing ring lower end external diameter embeds the external diameter of pipe equal to described metal, and described sealing ring external diameter seamlessly transits from top to bottom.
Described metal embeds infratubal port inwall and is provided with cannelure, it is embedded with sealing gasket in described cannelure, the outer wall of described sealing gasket is connected on the sidewall of described cannelure, the internal diameter of described sealing gasket embeds the internal diameter of pipe less than described metal, and the thickness of described sealing gasket is more than the height of described cannelure sidewall.
Closed type connecting pipe of pipeline based on said structure, in use, need that this metal is embedded pipe and insert in water pipe female joint, sealing gasket place end is connected in the sealed step of water pipe female joint, sealing ring is close to described metal and embeds on pipe, and along with metal embeds stretching into of pipe, sealing ring is gradually extruded by the inwall of water pipe female joint, fill up described metal and embed the gap between pipe and water pipe female joint, it is achieved metal embeds the sealing between pipe and water pipe female joint；When water pipe male joint be screwed into metal embed pipe time, sealing ring also can extrusion, fill up metal and embed the gap between inside pipe wall and water pipe male joint outer wall, until the termination of water pipe male joint is connected on described sealing gasket, it is achieved the two-stage of pipeline junction seals.
In the specific implementation, described sealing ring, sealing ring and sealing gasket all use food stage encapsulant to make, food stage sealed material good seal performance, does not produce harmful substance.
Beneficial effect: simple in construction, convenient dismounting；By embedding pipe upper end inwall at metal, sealing ring is set, be sticked outside upper end sealing ring, lower end inner wall arranges sealing gasket, realize metal embed pipe with pipe joint between, metal embed pipe with water pipe male joint between multi-sealed, sealing effectiveness is greatly improved, and improves the anti-seismic performance that pipeline connects simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Fig. 2 is that in Fig. 1, metal embeds tubular construction figure.
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 closed type connecting pipe of pipeline as shown in Figure 1, it it is critical only that: includes water pipe female joint 1 and water pipe male joint 7, in the hole 2, water pipe location of described water pipe female joint 1, fixed cover is provided with metal and embeds pipe 3, described metal embeds and is provided with female thread 31 on the inwall of pipe 3, the external screw thread 8 matched with female thread 31 it is provided with on the outer wall of described water pipe male joint 7, hole 2, described water pipe location is shoulder hole, this shoulder hole hole diameter embeds pipe 3 internal diameter less than described metal, form sealed step 4, as can be seen from Figure 2, embed pipe 3 upper port inwall at described metal and be provided with sealing ring 32, described sealing ring 32 upper-end inner diameter is equal to the internal diameter of described female thread 31, described sealing ring 32 bottom diameter is less than the internal diameter of described female thread 31, described sealing ring 32 internal diameter is bottom-up to be seamlessly transitted；
