Hand.
Further, the flexible sealing band is made of rubber.
The present invention has the advantages that the setting of scraper, can strike off the medium of runner inner surface adherency, have the special runner of guarantor clear
Clean, unimpeded advantage；The setting of flexible sealing band, it is ensured that the medium in runner will not enter in positioning case and regulating box, tool
There is the advantages of good airproof performance；The setting of regulating device, have the advantages that quickly, facilitate operation scraper.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram with scraper ball valve of the present invention.
Fig. 2 is a kind of E-E sectional view of Fig. 1 with scraper ball valve of the present invention.
Specific embodiment
According to Fig. 1,2 it is found that a kind of band scraper ball valve, comprising: valve body 1, left valve seat 2, right valve seat 10, sphere 5, valve rod
6, filler 7, gland 8 and driving device 9,1 middle part upper end of valve body are equipped with packing groove, and gland 8 is mounted on above packing groove, filler 7
Be glanded 8 to be fixedly installed at packing groove, inner flow passage is equipped with inside sphere 5 and is integrally placed at 1 inner cavity of valve body, 6 upper end of valve rod with
Driving device 9 connects, and 6 lower end of valve rod is protruded into 1 inner cavity of valve body after being passed down through gland 8 and filler 7 and connect with sphere 5, left and right
Valve seat 2,10 is arranged in 1 inner cavity of valve body and is respectively placed in the left and right side of sphere 5, and spinning ball 1 can be with left and right valve seat 2,10 phases
It cooperatively forms and opens or closes valve, which further includes scraper 4, flexible sealing band 3 and regulating device, and the scraper 4 is plectane
Shape structure is placed in inner flow passage, and 5 position of sphere of the inner flow passage lower part is equipped with consistent with inner flow passage axis direction and grows up
The guide groove of bar shaped, 4 lower part of scraper are equipped with the link block 11 protruded into the guide groove, and 5 lower part of sphere is fixed with positioning
Case 12, the positioning case 12 is interior equipped with locating slot consistent with the direction of guide groove and rectangularity, and length is equipped in the locating slot
The tooth form item 13 of bar shaped, the link block 11 are fixedly connected with tooth form item 13, and the flexible sealing band 3 is covered on guide groove top simultaneously
It is fixedly connected with 4 lower end of scraper, the regulating device includes regulating box 16, rack 15 and worm screw 14, and the regulating box 16 is solid
Fixed to be arranged in 1 lower part of valve body, the rack 15 is vertically arranged in regulating box 16, between 15 top of rack and tooth form item 13
