Detailed Description
Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and therefore are only examples, and the protection scope of the present invention is not limited thereby.
It is to be noted that unless otherwise specified, technical or scientific terms used herein shall have the ordinary meaning as understood by those skilled in the art to which the present invention belongs.
As shown in fig. 2-4, the utility model discloses an scour prevention fluid-discharge tube for three-phase separator flowing back avoids traditional flowing back pipeline to receive the direct washing away of sand grain in the turn when flowing back to prolong pipeline life, reduce the potential safety hazard. The utility model discloses an anti-scour liquid discharge pipe, which comprises a liquid discharge pipeline 1, wherein a three-way pipe 2 is connected to the liquid inlet port of the liquid discharge pipeline 1; the three-way pipe 2 comprises a first branch pipe and a second branch pipe perpendicular to the first branch pipe, the second branch pipe is communicated with the middle of the first branch pipe, the second branch pipe is connected with the liquid discharge pipeline 1 in a welded mode, and one end of the first branch pipe is arranged in a sealing mode.
The liquid flowing out of the tank body of the three-phase separator can directly flow into the sealed end of the first branch pipe, the sand grains in the liquid and the liquid flow to the sealed end of the first branch pipe and then decelerate, and then flow into the liquid discharge pipeline 1 reversely at a low speed and flow out of the liquid discharge pipeline 1. Because the sealed end of first branch pipe has born the impact and the erodeing of sand grain when liquid flows in to the sealed end of entering first branch pipe slows down the back, and the velocity of flow of liquid reduces, thereby greatly reduced the intensity of erodeing to the inner wall of drainage pipeline 1, prolonged drainage pipeline 1's life. During the actual production, as long as in time the inspection with change first sealed end of branch pipe can, make things convenient for the workman to overhaul.
Further, for convenient and three-phase separator sealing connection, all be provided with flange 3 at the first branch pipe both ends of three-way pipe 2, one of them flange 3 is sealed through flange lid 4, guarantees sealed effect, makes things convenient for workman installation operation simultaneously.
The flange 3 is connected with the flange cover 4 through bolts, the thickness of the flange cover 4 is 8cm-12cm, and the thickness of the flange 3 is 8cm-12 cm. In this embodiment, the preferable thickness of the flange cover 4 and the flange 3 is 10cm, so that the structural strength of the flange cover 4 and the flange 3 after connection is ensured.
A dual-phase steel plate 5 is arranged between the flange 3 and the flange cover 4, and the dual-phase steel plate 5 is attached to the inner wall of the flange cover 4. The dual phase steel plate 5 has high strength, good impact toughness, and good overall and local stress corrosion resistance, and can withstand long-term sand erosion. Meanwhile, after working for a period of time, only the flange cover 4 needs to be detached and the dual-phase steel plate 5 needs to be replaced, so that the cost is further saved.
