Abstract
It is related to the adjustable hard seal eccentric ball valve of eccentric ball valve, there is valve shaft on its valve body, sphere is connected on valve shaft, valve seals are connected on valve body, ball seal circle is connected on sphere, two ball seal circles adjust rubber ring between ball seal circle and sphere, ball seal circle adjusting screw is connected in across ball seal circle on sphere, ball seal circle fixing screws are withstood on across ball seal circle on sphere, and ball seal circle adjusting screw replaces with ball seal circle fixing screws to be distributed on sphere.The utility model is double eccentric, two way seal ball valves, and sealing ring is not only adjustable, but also solves the problems, such as that the ball seal circle sealing surface interference volume of its valve is excessive and compact-sized, and switch valve torque is small.
Description
Technical field
The utility model is related to arrive eccentric ball valve.
Background technology
To solve the problems, such as China central and west regions serious water shortage, country puts more effort to infrastructure investment, rationally divides
With making good use of water source.Large quantities of large-sized water transfer projects are put into operation in succession, in these large water transportation construction machines projects, it is long away from
From on waterline, to ensure the safe operation of pipe network equipment of pumping station, long distance line, need to be imported and exported in water pump, line branches
The key positions such as engaging portion install corresponding maintenance valve.And large-sized water transfer project water-supply-pipe line length, allotment water are big, in addition
These regional landform height rise and fall complexity, and water quality silt content is big, it requires that mating maintenance valve pressure rating is high, cap gauge
Lattice are big, seal wear-resistant damage.And the hard seal eccentric ball valve on these pipelines always exists the adjustment of sealing surface interference volume and is stranded
Difficulty, open and close valve torque is very big, sealing surface maintenance, replace difficult, sealing surface due to interference volume is too big and the problem of abrade.
Invention content
The purpose of this utility model is to provide：Adjustable hard seal eccentric ball valve, it is that one kind can adjust hard sealing
The excessive valve of the sealing surface interference volume of eccentric ball valve ball seal circle.
The technical solution of the utility model is realized as follows：
Adjustable hard seal eccentric ball valve, including valve body 1, sphere 2, valve shaft 3, valve seals 4, ball seal circle 5, ball
Body sealing ring adjusting screw 6, ball seal circle fixing screws 7, ball seal circle adjust rubber ring 8, have valve shaft 3, ball on valve body 1
Body 2 is connected on valve shaft 3, and valve seals 4 are connected on valve body 1, and ball seal circle 5 is connected on sphere 2, described two balls
Body sealing ring adjusts rubber ring 8 between ball seal circle 5 and sphere 2, and ball seal circle adjusting screw 6 passes through ball seal circle
5 are connected on sphere 2, and ball seal circle fixing screws 7 are withstood on across ball seal circle 5 on sphere 2, ball seal circle adjusting screw
6 replace with ball seal circle fixing screws 7 and are distributed on sphere 2.
The advantages of the utility model is：The utility model is double eccentric, two way seal ball valves, compact-sized, is sealed
The excessive difficulty for being not easy to adjust of sealing surface interference volume that circle is not only adjustable, but also solving hard seal eccentric ball valve ball seal circle
Topic, during Simultaneous Switching valve, torque is substantially reduced, and sediment prevention erosion is good.
Description of the drawings
FIG. 1 is a schematic structural view of the utility model；
Fig. 2 is I figure of Fig. 1；
Fig. 3 is II figure of Fig. 1；
Fig. 4 is the A direction views of Fig. 1.
Specific embodiment
Referring to attached drawing embodiment, the utility model is described further.
In Fig. 1-4：There is valve shaft 3 on valve body 1, sphere 2 is connected on valve shaft 3, and valve seals 4 are connected on valve body 1, ball
Body sealing ring 5 is connected on sphere 2, and described two ball seal circles adjust rubber ring 8 between ball seal circle 5 and sphere 2,
Ball seal circle adjusting screw 6 is connected in across ball seal circle 5 on sphere 2, and ball seal circle fixing screws 7 pass through ball seal
Circle 5 is withstood on sphere 2, and ball seal circle adjusting screw 6 replaces with ball seal circle fixing screws 7 to be distributed on sphere 2.It is adjustable
When formula hard seal eccentric ball valve sealing surface adjusts, ball seal circle fixing screws 7 are unclamped first, then adjust the adjustment of ball seal circle
Screw 6 adjusts ball seal circle 5 to suitable position, during the adjustment because ball seal circle adjustment rubber ring 8 contains always
Elastic force can support ball seal circle 5, facilitate the adjustment of ball seal circle 5, and ball seal circle is tightened after adjustment and fixes spiral shell
Nail 7, sealing surface are fixed to suitable position.
