Description
Technical Field
The utility model belongs to the technical field of pipe fitting connecting devices, and particularly relates to a water pipe connecting piece which is firm in connection between pipe fittings, can effectively prevent water leakage, water seepage or gas leakage and is high in sealing performance.
Background
The infinite length of the tap water pipe or the gas pipeline needs to depend on a plurality of short pipes with finite length to be connected in sequence for use, so the connection between the pipelines is particularly important; because the traditional connection between pipelines depends on the threading of threads on the pipelines, the pipelines are mutually screwed; the water leakage or water seepage phenomenon often occurs in the long-term actual use process, and if the water leakage or water seepage phenomenon is not timely treated, the leaked tap water can easily corrode accessories on the periphery of the water pipe, so that the service life of the water pipe is influenced; similarly, the gas supply conduit is also susceptible to leakage of gas flowing through the trachea when the gas pressure increases.
Disclosure of Invention
The utility model aims to provide a water pipe connecting piece which is reasonable in structural design, firm in installation and strong in sealing performance and can effectively prevent water seepage, water leakage or air leakage by utilizing multiple sealing ring layers aiming at the defects of the prior art.
The utility model is realized by the following technical scheme: water pipe connection spare that sealing performance is strong comprises hollow tube, outer hexagonal limit latch fitting and nut, its characterized in that: also comprises a hollow connector; the outer wall of the hollow connector is provided with an outer hexagonal edge part, an accommodating cavity for placing a sealing ring is arranged in an inner cavity of one end of the hollow connector, and internal threads are also arranged from the accommodating cavity to the inner wall of the port; a plurality of O-shaped sealing rings are placed in the accommodating cavity; the hollow connecting head is in threaded connection with one end of the outer hexagonal side locking piece, and the hollow pipe and the nut are sleeved at the other end of the outer hexagonal side locking piece.
The outer hexagonal side locking piece is a through pipe, external threads are arranged outside two ends of the through pipe, a vertical opening explosion groove is formed in the surface of one of the external thread ends, and an outer hexagonal side is arranged on the outer side of the middle of the through pipe.
The utility model has the beneficial effects that: compared with the prior art, the utility model has the advantages that under the condition that the hollow pipe does not need to be provided with the thread teeth, the plurality of O-shaped sealing rings are arranged in the hollow connector, the hollow connector is in threaded connection with one end of the outer hexagonal side locking piece, the hollow pipe is inserted into the other end of the outer hexagonal side locking piece and is locked by the nut, and the hollow pipe is reinforced by the wrench, so that the connection degree between the hollow connector and the hollow pipe is tighter, the phenomenon of water leakage and water seepage or air leakage is prevented after the plurality of O-shaped sealing rings are extruded by stress, the service life of a gas pipeline or a water pipeline can be greatly prolonged, and the manual maintenance cost is saved.

The following are specific names for each label in the figure: 1. a hollow tube; 2. an outer hexagonal side lock; 3. a nut; 4. an O-shaped sealing ring; 5. a hollow connector; 201. a flare slot; 501. a hexagonal edge portion; 502. an accommodating chamber; 503. an internal thread.
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.
Referring to fig. 1-3, the water pipe connector with high sealing performance comprises a hollow pipe 1, an outer hexagonal side locking piece 2 and a nut 3, and further comprises a hollow connector 5; an outer hexagonal edge part 501 is arranged on the outer wall of the hollow connector 5, so that the screwing operation is convenient, an accommodating cavity 502 for placing a sealing ring is arranged in an inner cavity of one end of the hollow connector 5, and an internal thread 503 is also arranged from the accommodating cavity 502 to the inner wall of the end port; a plurality of O-shaped sealing rings 4 are placed in the accommodating cavity 502; hollow connector 5 threaded connection is in the one end of outer hexagonal limit latch fitting 2 to with the whole extrusion of numerous O shape sealing washer 4 in holding chamber 502, hollow tube 1 and nut 3 cup joint the other end at outer hexagonal limit latch fitting 2, hollow tube 1 inserts and utilizes nut 3 to lock on the other end of outer hexagonal limit latch fitting 2. When an infinite length pipeline is needed, an infinite number of short hollow pipes 1 and hollow connectors 5 are required to be connected in sequence for use, the hollow pipes 1 and the hollow connectors 5 are completely connected by means of the nut 3, the outer hexagonal side locking piece 2 and an infinite number of O-shaped sealing rings 4, and the infinite number of O-shaped sealing rings 4 achieve the sealing effect after being extruded in the hollow accommodating cavity 502.
The outer hexagonal side locking piece 2 is a through pipe, external threads are arranged outside two ends of the through pipe, a vertical opening groove 201 is formed in the surface of one external thread end, and an outer hexagonal side is arranged outside the middle of the through pipe; after the bursting groove 201 is locked and connected with the nut 3, the position of the bursting groove is meshed with the nut 3 more tightly.
During installation, a plurality of O-shaped sealing rings 4 are sequentially installed in the hollow accommodating cavity 502, one end of the outer hexagonal side locking piece 2 is installed on the hollow connector 5 in a threaded mode, the nut 3 is sleeved on the outer hexagonal side locking piece 2, and finally the hollow tube 1 is inserted into one end, provided with the explosion groove 201, of the outer hexagonal side locking piece 2 and locked through the nut 3; the pipe with infinite length can be connected by the circular connection, and the connection combination degree between the hollow connector 5 and the hollow pipe 1 is very tight and the water seepage and the water leakage are not easy to occur through the arrangement of the O-shaped sealing ring 4 and the outer hexagonal side locking piece 2.
