Abstract
With the pipe joint of interior enlarging annular groove, comprise pipe joint body, pipe joint body is shaped with waterpipe jointing, and it is characterized in that described waterpipe jointing oral area is shaped with flaring ring, flaring ring inwall is shaped with enlarging annular groove, flaring ring is shaped with reducing ring.Flaring ring is shaped with by the oral area at waterpipe jointing, the inwall of flaring ring is shaped with enlarging annular groove, flaring ring is shaped with reducing ring, when seal ring is installed, only need utilize elasticity and the toughness of seal ring, enlarging annular groove can be put into after it being slightly out of shape, put into rear seal ring just to restore to the original state under restoring force effect, and after loading, seal ring top has reducing ring to block, bottom has waterpipe jointing to block, not easily deviate from, install very convenient, in addition fastening without the need to the component such as pressure ring, nut, structure is simple, reduces manufacture cost.
Description
Technical field
The utility model relates to pipe joint, particularly relates to the pipe joint with interior enlarging annular groove.
Background technique
In order to improve the sealing between pipe joint and water pipe; usual meeting arranges seal ring in pipe joint; to be sealed with pipe outer wall by seal ring and contact; prior art is on pipe joint, be shaped with enlarging annular groove; in enlarging annular groove, seal ring is set; seal ring arranges pressure ring; pressure ring arranges nut, after pipe joint is connected with water pipe, tightening nuts; by nut compressing pressure ring; pressure ring press seal circle, makes seal ring seal with water pipe and contacts, and this pipe joint structure is complicated; component are many, and manufacture cost is high.
Summary of the invention
The purpose of this utility model is the shortcoming existed to overcome prior art, and provide a kind of structure simple, seal ring is easy for installation, reduces the pipe joint with interior enlarging annular groove of manufacture cost.
The utility model with the technological scheme of the pipe joint of interior enlarging annular groove is: comprise pipe joint body, pipe joint body is shaped with waterpipe jointing, it is characterized in that described waterpipe jointing oral area is shaped with flaring ring, flaring ring inwall is shaped with enlarging annular groove, flaring ring is shaped with reducing ring.
The utility model discloses a kind of pipe joint with interior enlarging annular groove, flaring ring is shaped with by the oral area at waterpipe jointing, the inwall of flaring ring is shaped with enlarging annular groove, flaring ring is shaped with reducing ring, when seal ring is installed, only need utilize elasticity and the toughness of seal ring, enlarging annular groove can be put into after it being slightly out of shape, put into rear seal ring just to restore to the original state under restoring force effect, and after loading, seal ring top has reducing ring to block, bottom has waterpipe jointing to block, not easily deviate from, install very convenient, without the need to pressure ring, the component such as nut are in addition fastening, structure is simple, reduce manufacture cost.
The utility model is with the pipe joint of interior enlarging annular groove, and described pipe joint body is three-way union or elbow.As required, dissimilar pipe joint can be manufactured.The inwall of described enlarging annular groove is for facing directly, and the upper wall surface of enlarging annular groove and lower wall surface tilt to expand outwardly, and with waterpipe jointing inwall and reducing ring inwall arc transition.
Accompanying drawing explanation
Fig. 1 is the structural representation of three-way union with the pipe joint of interior enlarging annular groove;
Fig. 2 is the A place close-up schematic view of Fig. 1;
Fig. 3 is the structural representation of elbow with the pipe joint of interior enlarging annular groove.
Embodiment
The utility model relates to a kind of pipe joint with interior enlarging annular groove, as shown in Fig. 1-Fig. 3, comprise pipe joint body 1, pipe joint body is shaped with waterpipe jointing 2, it is characterized in that: described waterpipe jointing 2 oral area is shaped with flaring ring 3, flaring ring inwall is shaped with enlarging annular groove 4, flaring ring is shaped with reducing ring 5.By being shaped with flaring ring 3 at the oral area of waterpipe jointing 2, the inwall of flaring ring is shaped with enlarging annular groove 4, flaring ring is shaped with reducing ring 5, when seal ring 6 is installed, only need utilize elasticity and the toughness of seal ring, enlarging annular groove 4 can be put into after it being slightly out of shape, put into rear seal ring 6 just to restore to the original state under restoring force effect, and after loading, seal ring top has reducing ring 5 to block, bottom has waterpipe jointing 2 to block, not easily deviate from, install very convenient, in addition fastening without the need to the component such as pressure ring, nut, structure is simple, reduces manufacture cost.Described pipe joint body 1 is three-way union or elbow.As required, dissimilar pipe joint can be manufactured.The inwall 41 of described enlarging annular groove 4 is for facing directly, and the upper wall surface 42 of enlarging annular groove and lower wall surface 43 tilt to expand outwardly, and with waterpipe jointing 2 inwall and the transition of reducing ring 5 inwall circular arc 44.
