Specific implementation mode
As shown in Fig. 1, one kind of the utility model non-maintaining simple rotary spherical digester rotation vapour head, is used in intermittent-rotation formula
Rotary spherical digester pulping by cooking into vapour rotary part comprising ontology, a round end connecting tube 11, one for being equipped with left spherical flange 7 are set
There are fixing end connecting tube 12, the sealing ring 8 of right spherical flange 9；
Round end connecting tube 11, fixing end connecting tube 12 are divided into two opposite ends of ontology,
Sealing ring 8 is located between the left spherical flange 7 and the right spherical flange 9,
Round end connecting tube 11 is equipped with central flange 4, and leading screw 6 is equipped between central flange 4 and right spherical flange 9,
Clearance fit between leading screw 6 and central flange 4 and right spherical flange 9, leading screw 6 stretch out central flange 4 and 9 end face of right spherical flange
Outer end sheathed spring 3, and nut and washer 2 are installed in 6 end of leading screw and locked；
Above-mentioned sealing ring 8 is by the precompression of 6 both ends spring 3 of leading screw, left spherical flange 7, right ball with 8 both sides of sealing ring
