|Applicants:||JIANGSU SHUGUANG OIL DRILLING EQUIPMENT CO., LTD
|Title:||RING TUBE WATER SPRINKLER USED FOR DRILL PIPE QUENCHING|
A ring tube water sprinkler used for drill pipe quenching, comprising a frame (1), a front-mounted ring tube (2), a centre-mounted ring tube (3), bridge tubes (4), a water guide tube (5), nozzles (6), and a rear-mounted ring tube (7). The frame (1) is a conjoined frame, a small rectangular frame being positioned on one side of a large rectangular frame, the front-mounted ring tube (2), the centre-mounted ring tube (3), and the rear-mounted ring tube (7) being arranged in an orderly manner in the large rectangular frame, the water guide tube (5) being mounted on the small rectangular frame. The corresponding tube walls of the water guide tube (5) and all the ring tubes are provided with holes, matching holes being connected using the bridge tubes (4). 6-8 radially connected nozzles (6) are distributed on the inner walls of the round loops of all the ring tubes, a pressurised water source introduced by connecting the water guide tube (5) with an external water supply tube entering the ring tubes by means of the respective bridge tubes (4) and being sprayed from the matching nozzles (6), thereby forming a group of ring tubes that jointly spray water simultaneously and in different directions for quenching the outer walls of an in-built drill pipe. Water of the same temperature and quantity is sprayed from different directions onto each cross section, enabling the drill pipe to achieve uniform quenching quality.
