SUMMERY OF THE UTILITY MODEL
The utility model discloses a main objective provides a prevent plastic-coated steel pipe that joint department seeped water, problem in can effectual solution background art.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides a prevent plastic-coated steel pipe that joint department seeped water, which comprises a pipe body, and set up in the flange at body both ends, the inside annular liquid groove of having seted up of flange, the annular liquid groove extends to the outside that one side was kept away from each other to the flange, the feed liquor hole has been seted up to the position between the hole that the flange outward flange is located the flange, feed liquor downthehole surface and annular liquid groove intercommunication, annular liquid inslot intussuseption is filled with sealing liquid, pass through flange joint when two bodys, and use bolt and nut to fix, then pour into sealing liquid into from the feed liquor downthehole, sealing liquid fills annular liquid groove and fills the clearance between two flanges, the completion is sealed, can.
Furthermore, the sealing liquid is sealing glue, and the sealing glue is filled in the gap between the two flanges, so that the problem of water leakage at the joint can be effectively solved.
Further, the sealing liquid is butter.
Furthermore, the inner surface of the liquid inlet hole is in threaded connection with a plunger, the liquid inlet hole is sealed by the plunger through grease filled in the annular liquid groove, the grease can flow along with temperature change, a gap between the two flanges can be fully filled, and the whole sealing performance is guaranteed.
Furthermore, the positions, which are close to the annular liquid groove, of one side, away from each other, of the flange at one end of the pipe body are provided with flow-resisting convex blocks, the positions, which are located at the flow-resisting convex blocks, of the outer surface of the flange at the other end of the pipe body are provided with grooves matched with the flow-resisting convex blocks, and during installation, the flow-resisting convex blocks and the grooves are matched, so that sealing liquid is filled in the positions among the flow-resisting convex blocks, and the problem of liquid leakage caused by uneven flange surfaces.
The working principle and the beneficial effects are as follows: through the inside annular liquid groove of having seted up of flange, annular liquid groove extends to the outside that the flange kept away from one side each other, and the feed liquor hole has been seted up to the flange outward flange position between the hole of flange, feed liquor downthehole surface and annular liquid groove intercommunication, and annular liquid inslot intussuseption is filled with sealed liquid, can effectively solve the technical problem who exists among the background art.
(1) Through feed liquor downthehole internal surface threaded connection have the plunger, through the butter of annular liquid inslot intussuseption to by plunger shutoff feed liquor hole, the butter can flow along with temperature variation, can fully fill the clearance between two flanges, guarantee holistic leakproofness, can solve the problem that prior art exists effectively.
(2) The positions, which are close to the annular liquid groove, of one side, away from each other, of the flange at one end of the pipe body are provided with the flow blocking lugs, the positions, which are close to the annular liquid groove, of the outer surface of the flange at the other end of the pipe body are provided with the grooves matched with the flow blocking lugs, and during installation, the flow blocking lugs are matched with the grooves, so that sealing liquid is filled in the positions among the flow blocking lugs, and the problem of liquid leakage caused by uneven flange surfaces can be solved.
