Embodiment
Embodiment of the present utility model is described further below in conjunction with the accompanying drawings.
As shown in figure 1, the semisphere valve that flap sealing intensity is axially adjustable, it includes valve body 1, and the inside of valve body 1 is installed
There are final drive shaft 7 and flap rotary shaft 8, the both ends of the final drive shaft 7 are symmetrically installed with the first cam 3, first gear 4
With second gear 5；The second cam 11 being engaged with the first cam 3 is symmetrically installed with the flap rotary shaft 8, be provided with
The 3rd gear 10 that first gear 4 is engaged, the 4th gear 9 being engaged with second gear 5 is installed；3rd gear 10
It is arranged on the second cam 11 on axial drive shaft set 15, the axial drive shaft set 15 is sleeved in flap rotary shaft 8；It is described
Axial spacing maintainance block 16 is installed between final drive shaft 7 and flap rotary shaft 8.
Further, the both ends of the final drive shaft 7 and flap rotary shaft 8 are encapsulated in the inside of valve body 1 by bonnet 6.
Sealing position-limiting action well is played by described bonnet 6.
Further, water inlet 2 is provided with the valve body 1, first sealing valve is installed in the delivery port position of valve body 1
The seal valve seat 12 of seat 13 and second.It can be entered by described the first seal valve seat 13 and the second seal valve seat 12 between flap
Row coordinates and then plays a part of sealing.
Further, be provided with arc groove on the axial spacing maintainance block 16, two arc grooves respectively with main biography
The cambered surface close fit of moving axis 7 and flap rotary shaft 8.Two power transmission shafts can be ensured by described axial spacing maintainance block 16
Between spacing, make its centre-to-centre spacing constant.
Further, flanged plate, the flap are provided with the water pipe where the water inlet 2 and delivery port of the valve body 1
Flap 14 is installed in rotary shaft 8.It can be coordinated by described flap 14 between valve seat and play sealing work well
With improving sealing effectiveness, ensure that leakage efficiency.
Specific work process and operation principle of the present utility model are：
In valve closing process, final drive shaft 7 rotates with the first cam of moving gear 3, first gear 4 and second gear 5；
During final drive shaft 7 rotates 0 ~ 90 °, second gear 5 engages with the 4th gear 9, and first gear 4 departs from the 3rd gear 10 nibbles
Close, final drive shaft 7 drives second gear 5, and second gear 5 drives the 4th gear 9, and the 4th gear 9 drives 8 turns of flap rotary shaft
Dynamic, flap rotary shaft 8 drives flap 14 to rotate；When final drive shaft rotates 90 °, flap 14 rotates 90 °, with the first seal valve seat
13 have small gap；During final drive shaft 7 rotates 90 ° ~ 360 °, second gear 5 is disengaged from the 4th gear 9, and first
