Description
Technical field
It the utility model is related to a kind of ball valve.
Background technology
Ball valve is the control unit in fluid delivery system, is generally mounted between the pipeline of fluid delivery system, ball
Valve is then to drive opening and closing element rotation to realize being turned on and off for pipeline by valve rod, when using valve, according to actual flow
Demand, user of service will not open opening and closing element completely, but opening and closing element is rotated to actually required angle, but in opening and closing element
When not opening completely, current can impact when flowing through opening and closing element to opening and closing element outer wall, because opening and closing element is connected with valve rod
Connect, therefore opening and closing element belongs to the part that can be rotated under external force, when current constantly impact to opening and closing element, opens
The angle of closing member can change, and water flow size can also change therewith, and the voluntarily change of water flow can then influence
Water delivery effect, be unable to reach actually required effect, in the case where needing water flow constant, water flow it is no matter excessive or
It is too small, all easily occurs surprisingly, potential safety hazard being present.
The content of the invention
The technical problems to be solved in the utility model is to provide a kind of ball valve, and it can determine open angle in opening and closing element
Afterwards, it just will not be influenceed again by external force, ensure that water flow remains at actually required size.
The technical scheme in the invention for solving the above technical problem is：
The utility model discloses a kind of ball valve, including valve body and water inlet end located at valve body both sides, water side, valve

Mesopore 4 is simultaneously connected with handle 6, and the other end of valve rod 5 is located in valve body 1 and is connected with opening and closing element 7, and the valve rod 5 is passed outside mesopore 4
One end outside be fixed with driving gear 8, driving gear 8 is exposed to outside valve body 1；The valve body 1 is provided with a fixing axle 9；It is described
The top of fixing axle 9 is arranged with a bearing 10, and fixing axle 9 is connected by bearing 10 with position limited gear 11；The position limited gear 11
Lower surface extends downwardly out a position-limiting tube 12, activity spacing 13 between position-limiting tube 12 and fixing axle 9 be present；Outside the position-limiting tube 12
Wall is provided with an annular groove 14；A fixed plate 15 is fixed with the valve body 1, fixed plate 15 is adjacent to position-limiting tube 12, the fixation
The position relative with position-limiting tube 12 is provided with a screw 16 on plate 15, and the limited screw 17 to match with it is bolted with screw 16；
Described one end of limited screw 17 is provided with butterfly knob 18, and the other end presses in annular groove 14；The upper end edge of fixed plate 15
Extend accessory plate 19 towards the direction of valve rod 5, accessory plate 19 is located at the top of position limited gear 11；The upper surface of position limited gear 11 is set
There are some spacing holes 20 being circularly and evenly distributed；The accessory plate 19 is provided with the through hole 21 corresponding with spacing hole 20；One
Spacer pin 22 is through through hole 21 and inserts in spacing hole 20, and spacer pin 22 is in T fonts, and the head 2201 of spacer pin 22 is stuck in auxiliary
On plate 19.
The through hole 21 and spacing hole 20 are all curved, through hole 21, spacing hole 20 towards the position of valve rod 5 opposite direction
Bending；The through hole 21 is identical with the center of circle of spacing hole 20；The spacer pin 22 includes matching with through hole 21, spacing hole 20
Body 2202 is sold, pin body 2202 is curved, and pin body 2202 is identical with the center of circle of through hole 21, spacing hole 20.
The head of the spacer pin 22 is provided with a bail 23；The upper end of fixed plate 15 is fixed with a cotton rope 24, cotton rope
24 one end are connected on bail 23.
Application method of the present utility model is as follows：Before using ball valve, first pass through butterfly knob 18 and revolve limited screw 17
Go out, limited screw 17 is no longer pressed in annular groove 14, now position-limiting tube 12 is no longer limited, then by spacer pin 22 from limit
Position is extracted in hole 20, and now position limited gear 11 is no longer limited, when position-limiting tube 12 and position limited gear 11 can be rotated freely, limit
Position gear 11 can be with 8 free engagement rotation of driving gear, therefore valve rod 5 can freely be rotated, can be to the angle of opening and closing element 7
Carry out free regulation and control.
Then ball valve can be used, rotated by turn handle 6 with ovable valve stem 5, so as to drive opening and closing element 7 to rotate, realize
Opening and closing element 7 is turned on and off, and opening and closing element 7 is rotated to actually required angle, in order to ensure that opening and closing element 7 will not be by water
The influence of the impulsive force formed is flowed, now user of service can be screwed by butterfly knob 18 to limited screw 17, be made spacing
Screw 17 is pressed in annular groove 14, and under the pressure effect of limited screw 17, position-limiting tube 12 can not rotate, and then will limit
Position pin 22 is inserted in spacing hole 20 through through hole 21 again, and in the presence of spacer pin 22, position limited gear 11 is stuck again, and
Limited screw 17 is located at the side of position-limiting tube 12, belongs to cross spacing, and spacer pin 22 is located at the top of position limited gear 11, belongs to longitudinal limit
Position, it is spacing while transverse and longitudinal direction, the position of position limited gear 11, position-limiting tube 12 is carried out to the full extent it is stuck, in limiting tooth
Wheel 11 completely it is stuck in the case of, position limited gear 11 is stuck by driving gear 8 by the gear teeth so that valve rod 5 can not occur turn
Dynamic, the position of opening and closing element 7 being connected with valve rod 5 is limited, even if current constantly impact to opening and closing element 7, opening and closing element 7
It is unaffected, remains at original position, water flow is in actually required size all the time, be not in any
Because flow voluntarily changes caused accident, potential safety hazard is prevented.
Through hole 21, spacing hole 20, the pin body 2202 of spacer pin 22 are all in concentric arc, and arching trajectory is more conducive to spacer pin
22 insertion or taking-up, and through hole 21, spacing hole 20 are bent towards the opposite direction of the position of valve rod 5, therefore limited by pulling
The head 2201 of position pin 22 pulls out, and just can easily extract spacer pin 22, will not be limited in space, even if handle is just
Above spacer pin 22.
The head 2201 of spacer pin 22 is provided with bail 23, and the upper end of fixed plate 15 is fixed with cotton rope 24, and the one end of cotton rope 24 connects
It is connected on bail 23, therefore user of service directly can be pulled so as to extract spacer pin by cotton rope 24 to spacer pin 22
22, it can more reduce operating space, ensure that the operation to spacer pin 22 is smoothed out, will not be limited in space, and cotton rope 24
Presence can prevent dropping for spacer pin 22, avoid spacer pin 22 from losing the situation of stuck work of can not carrying out.
