Embodiment
The utility model is further described with reference to accompanying drawing.
Referring to Fig. 1, the utility model devises small-bore high pound level anti-cavitation regulating valve, including valve body, valve sleeve, valve
Bar, valve element, bonnet, it is characterised in that:The both sides of valve body 1 are fixed with valve port 1, valve port 2 14, valve body 1 using bolt
Centre offers valve opening 15, and the side of valve opening 15 center position on the upper side offers valve road 1 diagonally downward, the opposite side of valve opening 15
Position close to bottom offers the valve road 2 17 tilted upward, and the center of valve opening 15 is provided with valve sleeve 2, valve sleeve 2 with
The position that valve opening 15 is in contact is provided with valve seat pad, and the center of valve sleeve 2 is enclosed with valve element 4, and the center of valve sleeve 2 is opened up
There are four medium outflow balance channels 18, medium outflow balance channel 18 is distributed in the surrounding of the position of valve element 4, medium outflow balance
Dislocation offers four acclivitous media and flows into balance channel 19, the top of valve element 4 and the bottom of valve rod 3 between passage 18
Mutually fixed, the top of valve body 1 is mutually fixed using stud with bonnet 5, and valve rod 3 is then wrapped in the central position inside bonnet 5
Put, the position that bonnet 5 is in contact with valve sleeve 2 is provided with bonnet gasket, the outer rim of valve rod 3 positioned at the bottom position of bonnet 5 is arranged
There is carbon packing ring 6, the outer rim of valve rod 3 positioned at the middle position of bonnet 5 is arranged with guide sleeve 7, bushing 8, filler group 9 and filled out respectively
Expect gland 10, the bottom that clip and executing agency part 12 is respectively adopted in the both sides at the top of bonnet 5 is mutually fixed, the top use of clip
Hexagon-headed bolt is mutually fixed with pressing plate 11, and the top of the valve rod 3 is then connected through pressing plate 11 with executing agency part 12.
One end of valve road 1 is located at the top for the position that valve sleeve 2 is in contact with valve body 1, valve road in the utility model
