Abstract
The utility model discloses a combined type corrugated pipe which comprises a pipe body. The pipe body is formed by iron water pipes (2) and a corrugated pipe body (3) in a combined mode, the iron water pipes (2) are arranged at the two ends of the pipe body, the end portion of the iron water pipe (2) at one end of the tube body is connected with a connecting flange (1), at least one sealing ring (4) is in close fit to the outer circumferential wall of the end portion of the iron water pipe (2) at the other end of the tube body, and the outer circumferential wall of the sealing ring (4) is provided with a radial outwards-protruding annular protrusion (4.1). By means of the structure, the annular protrusion is arranged on the outer wall of the sealing ring, the annular protrusion is fitted in an installation hole, the extrusion quantity of the sealing ring is supplemented, therefore, the axial sealing effect is strengthened, and the sealing performance is better.
Description
Technical field
The utility model relates to the hydraulic tube piece technical field, is specifically a kind of for the Combined corrugated pipe on motor car engine.
Background technique
At present, bellows is applied to all trades and professions, wherein also uses on motor car engine, and with iron water pipe and combined bellows, to be adapted to various installation environments, is referred to as the Combined corrugated pipe.One end of the Combined corrugated pipe of prior art is welded with flange, and the other end is socketed with the O RunddichtringO.But, there is following shortcoming in the Combined corrugated pipe of this structure: because the effect of common this O RunddichtringO is axial seal, and the groove width of the annular groove of accommodating O RunddichtringO can be greater than the diameter of O RunddichtringO, therefore, when other component of Combined corrugated Guan Zaiyu connected, the O RunddichtringO of this joint is squeezed in annular groove can produce the distortion filling, if after plug repeatedly, the sealability of O RunddichtringO will variation, makes this joint produce the phenomenon of leaking.
The model utility content
Technical problem to be solved in the utility model is to provide a kind of avoiding to leak, thereby improve the Combined corrugated pipe of sealability.
For solving the problems of the technologies described above, the Combined corrugated pipe that the utility model provides, comprise the pipe body, described pipe body is formed by iron water pipe and combined bellows, and the two ends of pipe body are iron water pipe, wherein the end of the iron water pipe of an end is connected with adpting flange, and the outer circle wall of the iron water pipe end of the other end tightens is furnished with at least one seal ring, has the annular protrusion of radially outwardly projecting on the outer circle wall of described seal ring.
The quantity of described seal ring is two.
The shape of cross section of described annular protrusion is square.
After adopting above structure, the utility model compared with prior art has the following advantages: have annular protrusion on the outer wall due to seal ring, this annular protrusion is engaged in mounting hole, has replenished the amount of compression of seal ring, therefore, strengthened axial sealing effect, made sealability better; In addition, the setting of two seals circle has also guaranteed sealability more.
Description of drawings
Fig. 1 is the structural representation of the utility model Combined corrugated pipe.
Fig. 2 is the structural representation of seal ring in the utility model.
Wherein: 1, adpting flange; 2, iron water pipe; 3, bellows; 4, seal ring; 4.1, annular protrusion.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
By the structural representation of the utility model Combined corrugated pipe illustrated in figures 1 and 2 as can be known, it comprises the pipe body, described pipe body is combined by iron water pipe 2 and bellows 3, and the two ends of pipe body are iron water pipe 2, wherein the end of the iron water pipe 2 of an end is connected with adpting flange 1, the outer circle wall of iron water pipe 2 ends of the other end tightens is furnished with at least one seal ring 4, has the annular protrusion 4.1 of radially outwardly projecting on the outer circle wall of described seal ring 4.
In the present embodiment, the quantity of described seal ring 4 is two.
In the present embodiment, the shape of cross section of described annular protrusion 4.1 is square.
The utility model is not limited to above-described structure, and wherein, the quantity of seal ring 4 can be also three etc.; The shape of cross section of annular protrusion 4.1 can be also semicircle, trapezoidal, triangle etc.Within above these variations all fall into protection domain of the present utility model.
Claims (3)
1. Combined corrugated pipe, comprise the pipe body, described pipe body is combined by iron water pipe (2) and bellows (3), and the two ends of pipe body are iron water pipe (2), wherein the end of the iron water pipe (2) of an end is connected with adpting flange (1), it is characterized in that: the outer circle wall of iron water pipe (2) end of the other end tightens is furnished with at least one seal ring (4), has the annular protrusion (4.1) of radially outwardly projecting on the outer circle wall of described seal ring (4).
2. Combined corrugated pipe according to claim 1, it is characterized in that: the quantity of described seal ring (4) is two.
