Detailed Description
The first embodiment is as follows:
referring to fig. 1, 2 and 3, the medium and low pressure pipeline under-pressure leakage blocking device comprises two coaxially arranged tightening sleeves 10, wherein the tightening sleeves 10 are provided with circular holes 11 which are axially communicated, the tightening sleeves 10 are connected through a plurality of pull rods 20, and the axial distance between the tightening sleeves 10 is adjustable. And the inner side end surfaces of the round holes 11 of the two hooping sleeves 10 are provided with annular grooves for placing O-shaped sealing rings along the edges of the wheel pinna. The inner end surface refers to the end surface of the two clamping sleeves 10 facing each other.
When the three-way pipe 30 is blocked, the tightening sleeves 10 are respectively sleeved on the two line pipes 40 which are in butt joint with the left and the right of the three-way pipe 30, and the distance between the two tightening sleeves 10 is adjusted through the pull rod 20, so that the O-shaped sealing rings on the end faces of the inner sides of the tightening sleeves 10 are squeezed and deformed to be blocked in the gaps between the line pipes 40 and the three-way pipe 30 in butt joint.
Preferably, the diameter of the O-ring is larger than the depth of the annular groove 12, so that the O-ring can obtain better deformation when leaking in.
The tightening sleeve 10 is formed by splicing two semicircular pressing blocks 13, and two open sides of the pressing blocks 13 are respectively locked together through bolts, so that the tightening sleeve 10 can be easily locked on the wire tube 40.
The tightening sleeve 10 is provided with a plurality of connecting parts 14 at regular intervals on the periphery thereof, and the pull rod 20 is connected with the connecting parts 14 of the two tightening sleeves. Preferably, one end of the pull rod 20 is provided with a nut 21, the other end of the pull rod is provided with a threaded section, the connecting portion 14 is provided with a shaft hole for the screw rod to pass through, and the threaded section of the pull rod 20 is screwed with a nut 22. The axial distance of the two clamping sleeves 10 can be easily controlled by screwing in and out the nut 22.
Example two:
referring to fig. 4, the difference between the second embodiment and the first embodiment is: the end face of the inner side of the hooping sleeve 10 is provided with a sinking groove 15, the diameter of the sinking groove 15 is larger than that of the round hole 11, the round hole 11 is arranged at the center of the sinking groove 15, and the circumferential wall of the sinking groove 15 is provided with a sealing ring groove 16 for placing a sealing ring 60. The sink groove 15 and the seal ring groove 16 can protect the O-ring 50 at the opening of the circular hole 11 and form a secondary sealing effect.
Example three:
referring to fig. 5, the difference between the third embodiment and the first embodiment is: an annular groove is arranged only on the outer end face of the round hole of the right clamping sleeve 10, so that the O-shaped sealing ring 50 is positioned on the outer end face of the right clamping sleeve 10; the tie rod 20 is a screw structure, and the tie rod 20 is screwed with the connecting portion 14 of the left side clinch sleeve 10 and abuts against the connecting portion 14 of the right side clinch sleeve 10. Therefore, when the left clamping sleeve 10 is tightly sleeved on the conduit, the pull rod 20 can be rotated to push the right clamping sleeve 10 to move axially, so that the O-shaped sealing ring 50 of the right clamping sleeve 10 blocks the gap at the joint of the conduit.
