On sealing surface 26 on the outside of flush, so spool 4 during rotation moves down, can use lower cleaning brush 25 to medium channel
Sealing surface 26 in 5 is cleaned, until the sealing surface 21 on spool 4 contacts, realizes the closing inside shut-off valve.And
During spool 4 moves down, the valve body 1 of 26 two sides of sealing surface of medium channel 5 can be obstructed annular ring 19 in valve body 1
Top, make it that spool 4 not followed to move down, ring spring 18 compressed, and by 20 compressional deformation of Clean Brush for cleaning, be fitted in
The side-walls of rotary table 22.
When needing opening stop valve, handwheel 35 can be rotated backward according to above-mentioned steps, pass sequentially through valve rod 6,7 band of loop bar
On movable valve plug 8, during spool 8 moves up, lower cleaning brush 25 can the sealing surface 26 to medium channel 5 realize it is secondary clear
It is clean.
When needing to clean 21 face of sealing on spool 4, it is necessary to which keeping shut-off valve is open state, at this point, will
Sealing shroud 17 is move upwardly until and all moves on valve rod 6, then removes fixing bolt 16, rotates loop bar 7, keeps loop bar 7 opposite
Valve rod 6 rotates, and loop bar 7 drives terminal pad 8 to rotate on upper rotary table 22 at this time, and the rotation of terminal pad 8 drives ring spring 18
Rotation, so that annular ring 19 and its Clean Brush for cleaning of inside 20 be driven to rotate, Clean Brush for cleaning 20 carries out the sealing surface 21 of spool 4
Cleaning, it is easy to operate simple.After the completion of cleaning, the bolt hole 15 that loop bar 7 is turned to its bolt hole 15 and valve rod 6 is opposite, so
Fixing bolt 16 is penetrated in bolt hole 15 afterwards, the two is fixed, then pull down sealing shroud 17, covered in loop bar 7 and valve rod
6 junction.
Compared with prior art, the utility model from valve rod and can cover fixing bolt due to being provided with cleaning assemblies
It is removed on bar, by rotating loop bar, so that cleaning brush rotation is driven by terminal pad, so that the sealing surface to spool rotates
Cleaning, the dirt that its surface is adhered to is cleaned, and during closing valve, rotational valve core, lower clear on spool
Clean brush can follow valve core rotation to realize the cleaning to the sealing surface on medium channel, and the dirt that its surface is adhered to cleans
Get off, the two combines, it is ensured that the cleaning of valve body inner sealing surface avoids shut-off valve to prevent sealing surface from generating leakage
Leakage.
