DETAILED DESCRIPTION As shown in FIG. 1-5, a double-hole communicated pipe cap is used for communicating a first pipe body 100 and a second pipe body 200 which are adjacent in positions and opposite in flow directions. The center distance between the first pipe body 100 and the second pipe body 200 is L, the inner diameter of each of the first pipe body 100 and the seocnd pipe body 200 is D1, the outer diameter of each of the first pipe body 100 and the second pipe body 200 is D2, wherein the center distance L between the first pipe body 100 and the second pipe body 200 is greater than or equal to D2. The pipe cap is of 2 an integrated structure consisting of a cap edge 1, a cap side 2 and a cap bottom 3; the cap edge 1 is a port edge of the pipe cap, comprises a first port edge section 11 for connecting the first pipe body 100 and a second port edge section 12 for connecting the second pipe body 200, and further comprises two concave edge sections 13 used for smooth transition between the first port edge section 11 and the second port edge section 12; the radius of an inner cavity of each of the first port edge section 11 and the second port edge section 12 is R1, preferably D1=2R1, and the center distance between the first port edge section 12 and the second port edge section 12 is also L, that is, a 8-shaped cap edge 1 with a closed outer ring is formed from the first port edge section 11 to the concave edge section 13 at one side, then to the second port edge section 12, then to the concave edge section 13 at the other side, and finally back to the first port edge section 11; the cap edge 1 can achieve smooth transition with inner cavites of the first pipe body 100 and the second pipe body 200, wherein the first pipe body 100 and the second pipe body 200 are adjacently placed.
