Detailed Description
In order to make the present invention better understood by those skilled in the art, the technical solutions of the present invention are further described below with reference to the accompanying drawings and examples.
As fig. 1-4, the utility model discloses a spanner is used in assembly of upper assembling type ball valve disk seat, including a plurality of location axle 1, scale indicator 2, rotatory piece 3, pointer 4, a plurality of calorie of axle 5, a plurality of spring 6, a plurality of gasket 7, nut 8 and extension handle 9, calorie of axle 5 is installed in the bottom of rotatory piece 3, a plurality of calorie of axle 5 and 11 joints of pretension nut, and the top of valve body 15 is arranged in to location axle 1, and scale indicator 2 arranges the top of location axle 1 in.
The utility model discloses in the assembling process, assemble the spanner subassembly respectively on the entrance point and the exit end of ball valve, disk seat 12 is fixed at 15 disk seat holes of valve body. The pre-tightening nut 11 and the valve seat 12 are in a threaded fit structure. When the extension handle 9 is rotated, the pretensioned nut 11 is rotated and moved distally, and the leaf spring 13 is compressed. The compression ring 14 controls the maximum compression of the plate spring and avoids the plate spring from generating overpressure and failing.
