Abstract
The utility model discloses a fast connecting pipe piece. The inner wall of the open end of the fast connecting pipe piece is provided with connecting threads and the tail end of the connecting threads is provided with an annular boss. The annular boss is provided with an annular slot which is provided with a matched elastic sealing ring. When a pipe is connected with the fast connecting pipe piece through the connecting threads, the pipe presses the elastic sealing ring in the annular slot to reach a sealing purpose. Because the fast connecting pipe piece connects pipes through the connecting threads, the fast connecting pipe piece can bear large pressure and can be safely used. Simultaneously, the fast connecting pipe piece uses the elastic sealing ring, so the fast connecting pipe piece has the advantages of construction easiness and quickness and no leakage.
Description
The utility model relates to a kind of pipe fitting, but especially a kind of fast-connection pipeline.
Existing pipe fitting joint mostly is and is threaded, and twines unsintered tape or fiber crops on the screw thread in order to sealing.The construction of this joint is loaded down with trivial details and can not guarantee construction quality, not only wastes time and energy and can occur because of sealing the phenomenon of bad seepage.The poisonous connection that can not be used for drinking-water pipe of unsintered tape.Also have a kind of quickly jointed tubular workpieces to rely on the elastic seal cartridge of the outer suit of locking nut locking pipe to reach the purpose that connects soon.Though this pipe fitting connects easy to be quick, joint can be thrown off when internal pressure is big, poor reliability during use.
The purpose of this utility model is to provide a kind of connection fast and convenient and operational safety good, the quickly jointed tubular workpieces of ne-leakage.
For reaching above-mentioned purpose the utility model quickly jointed tubular workpieces opening inwall connecting thread is arranged, on the screw tip inner tubal wall annular boss is arranged, have circular groove on the boss at screw tip place, the elastic seal ring that matches with groove is arranged in the groove.
The circular groove slot opening bottom land of opening on the annular boss is narrow, the correspondingly-shaped of the elastic seal ring in the groove for matching with groove.
After adopting said structure, because the quickly jointed tubular workpieces joint is for being threaded, so use reliable bearing capacity big.When pipe is linked to each other with quickly jointed tubular workpieces by connecting thread, elastic seal ring is headed in the circular groove and reaches by the extruding elastic seal ring purpose of sealing.It is narrow that circular groove is made the slot opening bottom land, and the correspondingly-shaped of elastic seal ring for matching with groove makes the sealing effect of quickly jointed tubular workpieces better like this in the groove.Forms such as that this quickly jointed tubular workpieces can be made into is two logical, threeway, four-way are used for the different condition lower linking tube and use.
Embodiment is further described the utility model below in conjunction with accompanying drawing.
Fig. 1 is the structural representation that the utility model quickly jointed tubular workpieces two leads to.
Fig. 2 is the structural representation of the utility model quickly jointed tubular workpieces threeway.
The both ends open place inwall of quickly jointed tubular workpieces two logical 2 has connecting thread as shown in Figure 1, on the inner tubal wall of screw tip annular boss is arranged.Have circular groove 4 on the boss at screw tip place, the cross section of groove 4 is a triangle.Elastic seal ring 3 with matching is arranged in the groove 4.When pipe 1 joins by connecting thread and quickly jointed tubular workpieces 2 elastic seal ring 3 is clamp-oned the purpose that reaches sealing in the circular groove 4.
As shown in Figure 2, three opening inwalls of the utility model quickly jointed tubular workpieces threeway 5 have connecting thread, on the inner tubal wall of screw tip annular boss are arranged.Have circular groove 8 on the boss at screw tip place, the cross section of groove 8 is trapezoidal.Elastic seal ring 7 with matching is arranged in the groove 8.When pipe 6 joins by connecting thread and quickly jointed tubular workpieces 5 elastic seal ring 7 is clamp-oned the purpose that reaches sealing in the circular groove 8.
Claims (2)
1, a kind of quickly jointed tubular workpieces is characterized in that said quickly jointed tubular workpieces opening inwall has connecting thread, on the screw tip inner tubal wall annular boss is arranged, and has circular groove on the boss at screw tip place, and the elastic seal ring that matches with groove is arranged in the groove.
2, quickly jointed tubular workpieces according to claim 1 is characterized in that the circular groove slot opening bottom land of opening on the annular boss is narrow, the correspondingly-shaped of the elastic seal ring in the groove for matching with groove.
