Detailed Description

The invention will be further explained with reference to the drawings and the specific embodiments.

Please refer to fig. 1 to 3, the utility model discloses a seal assembly for piping erection, including rubber valve body 1, tightly decide handle 2 and expansion valve 3, the inside holding tank 4 that is provided with of rubber valve body 1, the shape of expansion valve 3 with holding tank 4 matches, holding tank 4 with expansion valve 3 is the round platform form, just 1 internally mounted of rubber valve body has screw rod 5, screw rod 5 passes holding tank 4 inserts inside the expansion valve 3, screw rod 5 is located the one end threaded connection of expansion valve 3 has interior concave bolt 6, interior concave bolt 6 imbeds expansion valve 3 keeps away from the one end surface of holding tank 4, just expansion valve 3 is located the cross-sectional diameter of the inside one end of holding tank 4 is less than expansion valve 3 keeps away from the cross-sectional diameter of the one end of holding tank 4, tightly decide handle 2 includes outer convex spiral shell head 7 and torsion bar 9, outer convex spiral shell head 7 is connected in torsion bar 9 tip, tightly decide handle 2 one end be connected with outer convex spiral shell head 7, the shape of outer convex spiral shell head 7 with interior concave bolt 6's shape matches.

In this embodiment, when needs carry out the shutoff to the pipeline, through inserting rubber valve body 1 inside the pipeline and tentatively block up, only inside the evagination spiral shell head 7 that will tightly decide 2 tip of handle inserts the inside indent bolt 6 of expansion valve 3, make evagination spiral shell head 7 and indent bolt 6 joint together, later rotate tightly decide handle 2 in order to drive indent bolt 6 through evagination spiral shell head 7 and rotate, in order to drive expansion valve 3 along screw rod 5 to the inside removal of holding tank 4 through indent bolt 6, thereby make expansion valve 3 constantly extrude holding tank 4, in order to make rubber valve body 1 produce deformation in order to enlarge to the outside, thereby get up the pipeline shutoff, in order to prevent the weeping, be convenient for the pipeline maintenance. After the pipeline maintenance is finished, the fastening handle 2 is rotated in the opposite direction, so that the inward-concave bolt 6 drives the expansion valve 3 to move outwards along the screw rod 5, the expansion valve 3 is continuously moved out of the accommodating groove 4, the rubber valve body 1 is correspondingly deformed and separated from the inner wall of the pipeline, and the rubber valve body 1 is extruded by means of medium pressure in the pipeline, so that the rubber valve body 1 is taken out, and the pipeline maintenance process is finished.

In some embodiments, the end of the screw rod 5 penetrates through the female screw bolt 6, and the male screw head 7 is internally provided with a receiving cavity 8 matched with the end of the screw rod 5, so that after the female screw bolt 6 rotates on the screw rod 5, the screw rod 5 can be inserted into the receiving cavity 8 on the male screw head 7, and the operation is convenient.

Further, the inside of the torsion bar 9 is communicated with the accommodating cavity 8, the inside of the torsion bar 9 is of a hollow structure, the diameter of the torsion bar 9 is larger than that of the accommodating cavity 8, and when the expansion valve 3 moves along the screw 5 by a distance larger than the depth of the accommodating cavity 8, the screw 5 Shu Die can be inserted into the torsion bar 9 when the expansion valve 3 continues to move, so that the torsion bar 9 is continuously rotated to drive the expansion valve 3 to rotate, and the position of the expansion valve 3 is adjusted.

In some embodiments, the screw 5 is located at the end of the expansion valve 3 flush with the outer end surface of the expansion valve 3.

In still other embodiments, a folding wrench 10 is installed at an end of the torsion bar 9 away from the male screw 7 to facilitate the rotation of the torsion bar 9, and the torsion bar 9 is a telescopic rod structure, such as a screw rod telescopic structure, with adjustable length, which can better meet practical operating requirements.
