Description
Technical field
This utility model belongs to connecting pipeline structure technical field, specifically, relates to a kind of closed type 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 head 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: 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；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 pipe joint.Concrete technical scheme is as follows:
A kind of closed type 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 and is provided with female thread on the inwall of pipe, 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, 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 pipe joint based on said structure, in use, need that this metal is embedded pipe and insert in water pipe head, sealing gasket place end is connected in the sealed step of water pipe head, 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 head, fill up described metal and embed the gap between pipe and water pipe head, it is achieved metal embeds the sealing between pipe and water pipe head；When extension tube attached be screwed into metal embed pipe time, sealing ring also can extrusion, fill up metal and embed pipe metal and embed the gap between inside pipe wall and extension tube attached outer wall, until the termination of extension tube attached is connected on described sealing gasket, it is achieved the two-stage of extension tube attached 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 extension tube attached 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 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 and is provided with female thread 31 on the inwall of pipe 3, 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, 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.
As can be seen from Figure 2, outer wall has been sticked sealing ring 33, and described sealing ring 33 upper end external diameter embeds the external diameter of pipe 3 more than described metal, and described sealing ring 33 lower end external diameter embeds the external diameter of pipe 3 equal to described metal, and described sealing ring 33 external diameter seamlessly transits from top to bottom.
By Fig. 2 it is also seen that, lower port inwall is provided with cannelure 34, it is embedded with sealing gasket 35 in described cannelure 34, the outer wall of described sealing gasket 35 is connected on the sidewall of described cannelure 34, the internal diameter of described sealing gasket 35 embeds the internal diameter of pipe 3 less than described metal, and the thickness of described sealing gasket 35 is more than the height of described cannelure 34 sidewall.
