Abstract
The utility model discloses a screw pipe hoop for jointing motor-pumped well pipe consisting of two ladder ring-shaped half-pipe hoops. When the utility model is used, the external sections of two half-pipe hoops are sleeved on two connected pipes respectively and connected and fixed by a cylindrical pin. The internal section of the left half-pipe hoop is positioned between the two connected pipes and welded with the pipe body, and the internal section of the right half-pipe hoop is sleeved on the left half-pipe hoop in thread connection. The pipe hoop has a reasonable structure and good connecting performance. The pipe body connected by the pipe hoop has high strength, long life and low cost.
Description
The utility model relates to the screw-type pipe collar that a kind of motor-pumped well pipe connects, and belongs to the linkage of motor-pumped well pipe.
At present, China's motor-pumped well pipe uses plain cast iron pipe and spiral welded pipe, ERW, seamless pipe more, and the connected mode of plain cast iron pipe is that screw thread directly connects, the processing cost height, and stress is concentrated, and tensile strength is low, is prone to accident.Spiral welded pipe, ERW and seamless pipe cost height, corrosion-resistant, the life-span is short.Recently the someone uses ductile iron pipe rivet welding stirrup formula connection method, and this method can not seal, and infiltration, drainage are arranged, and can not use the buoyancy downhole technique.
The purpose of this utility model is to have proposed the screw-type pipe collar that a kind of motor-pumped well pipe connects at the deficiency of the said goods, and the body portion processing that this pipe collar connects is simple, the tensile strength height, and security performance is good.The tubing cost is low, good corrosion resistance, and the life-span is long.Switching performance is good between pipe collar and the body, does not have infiltration, drainage, is specially adapted to deep-well buoyancy downhole technique.
The purpose of this utility model is realized by following measures: the utility model is made up of left semicanal hoop and right semicanal hoop, left and right sides two halves pipe collar is ladder garden annular, the internal diameter of outer section is equal to the external diameter of body, Duan Shangjun has the garden column pin hole that is connected usefulness with body outside, the internal diameter of left side semicanal hoop inner segment equates with the internal diameter of body, the inner segment of right semicanal hoop is sleeved on the left semicanal hoop inner segment, between for being threaded.When install connecting, outer section of left semicanal hoop is enclosed within on the body, and inner segment and welds with two bodys between two bodys mutually, with anti-seep water.Outer section of right semicanal hoop is sleeved on the body, and inner segment is sleeved on the inner segment of left semicanal hoop, outer section of left and right sides two halves pipe collar with body between all have the garden pin to fix to be connected.
The utility model is rational in infrastructure, and is easy to use, and switching performance is reliable.The body processing that this screw-type pipe collar connects is simple, the intensity height, and the life-span is long.The comprehensive well-digging cost that adopts this screw-type pipe collar to connect body reduces by 50%, and the zero defects rate reaches 100%.
Below in conjunction with accompanying drawing embodiment of the present utility model is described in detail:
Fig. 1 is the user mode sectional view of the screw-type pipe collar of motor-pumped well pipe connection.
Fig. 2 is the left semicanal hoop right view of the screw-type pipe collar of motor-pumped well pipe connection.
Fig. 3 is the A-A view of Fig. 2.
Fig. 4 is the right semicanal hoop sectional view of the screw-type pipe collar of motor-pumped well pipe connection.
Fig. 5 is the left view of Fig. 4.
Know by Fig. 1-5, present embodiment is made up of left semicanal hoop (1) and right semicanal hoop (2), left and right sides two halves pipe collar is ladder garden annular, the internal diameter of outer section all equates with body (3) external diameter, Duan Shangjun has the garden column pin hole (4) that is connected usefulness with body (3) outside, the internal diameter of left side semicanal hoop (1) inner segment equates that with the internal diameter of body (3) inner segment of right semicanal hoop (2) is sleeved on left semicanal hoop (1) inner segment, and is threaded.Connect when using, outer section of left semicanal hoop (1) is enclosed within on the body (3), and inner segment is positioned between two bodys (3), and welds mutually with two bodys (3), leaks with percolation-proof.Outer section of right semicanal hoop (2) is sleeved on the body (3), inner segment is sleeved on the inner segment of left semicanal hoop (1), left and right sides two halves pipe collar (1), (2) outer section with body (3) between all have garden pin (4) to fix to be connected, the axis of the axis of garden pin (4) and body (3) is perpendicular, the inner of garden pin (4) does not exceed the inwall of body (3), the outer end does not exceed outer section bus of pipe collar (1) or (2), and welds with its external surface.Garden pin (4) on the asymmetric bus can be positioned at different gardens on week.
Claims (1)
1, a kind of screw-type pipe collar of motor-pumped well pipe connection, form by left semicanal hoop and right semicanal hoop, the garden column pin hole that the usefulness that is connected with body is all arranged on the outer section of left and right sides two halves pipe collar, it is characterized in that: left semicanal hoop (1) is ladder garden annular with right semicanal hoop (2), the internal diameter of outer section all equates with the external diameter of body (3), the internal diameter of left side semicanal hoop (1) inner segment equates that with the internal diameter of body (3) inner segment of right semicanal hoop (2) is sleeved on left semicanal hoop (1) inner segment, between for being threaded.
