Detailed Description

The present invention will be described in detail with reference to the accompanying drawings and examples.

Referring to fig. 1 and 2, for the utility model discloses a handle for two-way sealed ultralow temperature ball valve that floats of forged steel, including lock joint lid 1, lock joint lid 1 passes through bolt fixed connection with the case, and the periphery welded fastening of lock joint lid 1 has at least one rotation to 2, rotates 2 preferred to set up in pairs, and is equipped with the gap between 2 in pairs, rotates 2 along the outside extension of the direction of keeping away from the case. The middle part of the rotating handle 2 is provided with a bending section of a broken line type, the bending section inclines upwards, the bending section comprises a first bending end 3 and a second bending end 4 which are sequentially connected, the first bending end 3 is located between the buckling cover 1 and the second bending end 4, the first bending end 3 and the second bending end 4 are provided with obtuse angle openings, the obtuse angle opening of the first bending end 3 is inclined upwards, and the obtuse angle opening of the second bending end 4 is inclined downwards. The end of the rotating handle 2 far away from the buckling cover 1 is gradually reduced. Rotate 2 and be equipped with a plurality ofly and set up in pairs, two rotations in every centering are located the rotation 2 both sides, and in pairs rotate to weld between 2 horizontally connecting plate 5, and connecting plate 5 is buckled end 4 from the second and is extended along the tip of keeping away from lock joint lid 1, and is located and rotates the upside of 2, and in pairs is rotating 2 intervals and is dwindled along the direction of keeping away from lock joint lid 1 gradually, and the one end that lock joint lid 1 was kept away from to connecting plate 5 dwindles gradually. The connecting plate 5 does not completely cover the gap.

If the staff rotate the rotating handle 2 by hands, a hollow pipe sleeve can be used on the rotating handle 2 and the connecting plate 5 to apply force so as to increase the moment. Rotate 2 and the same one side of connecting plate 5 and seted up joint groove 6, joint groove 6 does not run through and rotates 2 one end of keeping away from lock joint lid 1, and when the pipe tip pushed down, the edge of pipe tip can the butt in joint groove 6, conveniently prescribes a limit to the pipe and rotates the relative position of 2, makes the pipe fix with rotating the relative position of 2. Rotate 2 and keep away from the side of connecting plate 5 and be provided with side thread strip 7, in pairs rotate 2 on the side thread strip 7 cooperate and with same internal thread looks threaded connection, can drill out the internal thread with side thread strip 7 adaptation in external pipe is inside, external has the internal thread pipeline can threaded connection on a set of rotation 2, realizes the pipe and rotates the fixed of relative position between 2.

The buckling cover 1 and the second bending end 4 are welded and fixed or integrally provided with a triangular reinforcing rib 8, and the reinforcing rib 8 is positioned in the obtuse angle of the first bending end 3. The side edge of the reinforcing rib 8 far away from the first bending end 3 is a straight connecting line between the second bending end 4 and the fastening cover 1, and the reinforcing rib 8 is fixedly welded with a support bar 9 which inclines upwards at the straight connecting line.
