The invention discloses a two-stage leak-proof metal inlaid pipe which comprises a pipe body. An internal thread is arranged on the inner wall of the pipe body. The two-stage leak-proof metal inlaid pipe is characterized in that a sealing ring is arranged on the inner wall of an upper end opening of the pipe body; the inner diameter of the upper end of the sealing ring is equal to that of the internal thread; the inner diameter of the lower end of the sealing ring is smaller than that of the internal thread; the inner diameter of the sealing ring transits smoothly from bottom to top; a sealing loop is attached to the outer wall of the pipe body; the outer diameter of the upper end of the sealing loop is larger than that of the pipe body; the outer diameter of the lower end of the sealing loop is equal to that of the pipe body; the outer diameter of the sealing loop transits smoothly from top to bottom; an annular groove is formed in the inner wall of a lower end opening of the pipe body; a sealing gasket is inlaid in the annular groove; the outer wall of the sealing gasket abuts against the side wall of the annular groove; the inner diameter of the sealing gasket is smaller than that of the pipe body; the thickness of the sealing gasket is larger than the height of the side wall of the annular groove. The two-stage leak-proof metal inlaid pipe has the beneficial effects that the structure is simple, and dismounting is convenient; the sealing ring is arranged on the inner wall of the upper end of the metal inlaid pipe, the sealing loop is attached to the outer side of the upper end, and the sealing gasket is arranged on the inner wall of the lower end, so that the sealing effect is greatly improved, and meanwhile the shock resistance of pipeline connection is improved.
Description
Technical field
The invention belongs to metal and embed pipeline configuration technical field, specifically, relate to a kind of two-stage leakproof metal and embed pipe.
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 of water pipe and water pipe adapter, 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 water pipe 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: the connection sealing of water pipe and water pipe adapter is bad, 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 the metal of two-stage leakproof easily embed pipe.Concrete technological scheme is as follows:
A kind of two-stage leakproof metal embeds pipe, comprise body, the inwall of described body is provided with internal thread, its key is: described body upper end-hole inwall is 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, and described seal ring internal diameter is bottom-up to be seamlessly transitted;
Outer wall has been sticked seal ring, and described seal ring upper end external diameter is greater than the external diameter of described body, and described seal ring lower end external diameter equals the external diameter of described body, and described seal ring external diameter seamlessly transits from top to bottom;
Lower end mouth inwall 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, and the internal diameter of described sealing gasket is less than the internal diameter of described body, and the thickness of described sealing gasket is greater than the height of described circular groove sidewall.
Metal based on said structure embeds pipe, in use, needing this metal to be embedded pipe inserts in water pipe adapter, sealing gasket place end is connected on the limited step of water pipe adapter, seal ring is close on described body, and along with metal embeds stretching into of pipe, seal ring is extruded by the inwall of water pipe adapter gradually, fill up the gap between described body and water pipe adapter, realize the sealing between metal embedding pipe body and water pipe adapter; When externally connected pipe is screwed into body, seal ring also can extrusion, fills up metal and embeds gap between pipe inboard wall of tube body and externally connected pipe outer wall, until the termination of externally connected pipe is connected on described sealing gasket, realize the two-stage sealing of externally connected pipe.
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; Arrange seal ring by embedding pipe upper end inwall at metal, outside, upper end has been sticked seal ring, and lower end inner wall arranges sealing gasket, and sealing effect improves greatly, improves the anti-seismic performance that pipeline connects simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with drawings and Examples, the invention will be further described:
A kind of two-stage leakproof metal as shown in Figure 1 embeds pipe, comprise body 3, the inwall of described body 3 is provided with internal thread 31, its key is: described body 3 upper end-hole inwall is provided with seal ring 32, described seal ring 32 upper-end inner diameter equals the internal diameter of described internal thread 31, described seal ring 32 bottom diameter is less than the internal diameter of described internal thread 31, and described seal ring 32 internal diameter is bottom-up to be seamlessly transitted;
As can be seen from Figure 1, outer wall has been sticked seal ring 33, and described seal ring 33 upper end external diameter is greater than the external diameter of described body 1, and described seal ring 33 lower end external diameter equals the external diameter of described body 1, and described seal ring 33 external diameter seamlessly transits from top to bottom;
Also can be found out by Fig. 1, lower end mouth inwall is provided with circular groove 34, sealing gasket 35 is embedded with in described circular groove 34, the outer wall of described sealing gasket 35 is connected on the sidewall of described circular groove 34, the internal diameter of described sealing gasket 35 is less than the internal diameter of described body 1, and the thickness of described sealing gasket 35 is greater than the height of described circular groove 34 sidewall.
