Detailed Description
The present invention will be described in detail with reference to the accompanying drawings.
The structure of the tapered sliding sleeve pipe fitting provided by the embodiment is shown in fig. 1, and comprises a bushing 1 and a sliding sleeve 2, wherein the number of the sliding sleeve 2 is two.
The bush 1 is symmetrical structure, and the inner wall of the bush 1 is straight and uniform in size. As shown in fig. 2, the outer wall of the liner 1 is in a drum shape, and the outer wall of the liner 1 is formed by sequentially connecting a first straight section A3, a first tapered section a4, a first straight section B5, a first tapered section a '6 and a first straight section a' 7. The first straight section A3 and the first straight section A ' 7 are symmetrical about the radial symmetry plane of the bushing, the first straight section A3, the first straight section A ' 7 and the first straight section B5 are all cylindrical, the diameters of the first straight section A3 and the first straight section A ' 7 are equal, and the diameter of the first straight section A3 is smaller than that of the first straight section B5. The first conical section A4 and the first conical section A '6 are symmetrical about a radial symmetry plane of the bushing, the first conical section A3 and the first conical section A' 36 are both in a circular truncated cone shape, the diameter of the first flat section A3 is equal to the smallest diameter of the first conical section A4, and the diameter of the first flat section B5 is equal to the largest diameter of the first conical section A4. The first straight section B5 is symmetrically provided with annular bulges 8.
The sliding sleeve 2 has two. The outer wall of the sliding sleeve 2 is straight and uniform in size. As shown in fig. 3, the inner wall of the sliding sleeve 2 is composed of a second straight section a9, a second conical section 10 and a second straight section B11 which are connected in sequence, the second straight section a9 and the second straight section B11 are both cylindrical, the second conical section 10 is in a circular truncated cone shape, the diameter of the second straight section a9 is smaller than that of the second straight section B, the diameter of the second straight section a9 is equal to the minimum diameter of the second conical section 10, and the diameter of the second straight section B11 is equal to the maximum diameter of the second conical section 10. The second straight section B11 is provided with an annular groove 12.
