Specific embodiment
In order that the purpose of this utility model, technical scheme and advantage become more apparent, below in conjunction with the accompanying drawings and specifically
Embodiment is described further to this utility model.It should be appreciated that specific embodiment described herein is only in order to explain this reality
With new, it is not used to limit this utility model.Based on the embodiment in this utility model, those of ordinary skill in the art are not having
There is the every other embodiment being obtained under the premise of making creative work, broadly fall into the scope of this utility model protection.
As depicted in figs. 1 and 2, a kind of inside screw nonrising stem type gate valve opens and closes the display device of degree, is arranged on the upper end of inside screw nonrising stem type gate valve 1,
Including protective cover 11, the bearing block 2 that is arranged in protective cover 11, driving gear 3, driven gear 4, bearing 5, screw rod 6, sliding shoe
8th, protective cover 11 and be arranged on keying degree label 9 and open-shut direction sign board 10 on protective cover 11, open-shut direction mark
Board 10 is located at the top of keying degree label 9；Screw rod 6 is connected by rolling bearing with bearing block 2, screw rod 6 flexible rotation, opens and closes
Moment of torsion required for inside screw nonrising stem type gate valve 1 will not increase；Driving gear 3 is arranged on the valve stem top of inside screw nonrising stem type gate valve 1, under handwheel 12
Side, is connected with flat key；
Driving gear 3 is meshed with driven gear 4, constitutes a pair of gear pair；Driven gear 4 is arranged on screw rod 6 top, uses
Flat key connects；It is labeled with graduation mark on keying degree label 9；First opening 13 is offered on keying degree label 9；Protective cover 11
On offer second opening corresponding with the first opening 13, the second opening is identical with the first opening 13 size；The one of sliding shoe 8
End can be arranged on screw rod 6 up or down through the second opening, threadeds with screw rod 6, and the other end is located at keying degree mark
In first opening 13 of board 9, the described other end is provided with pointer 14, pointer 14 is used for indicating the quarter on keying degree label 9
Degree line.Protective cover 11 is fixed by bolts to the top of inside screw nonrising stem type gate valve 1；Bearing block 2 and the stuffing box one piece casting of inside screw nonrising stem type gate valve 1.
Driving gear 3 is identical with the modulus of driven gear 4, and the number of teeth of driving gear 3 is less than the number of teeth of driven gear 4, behaviour
When making inside screw nonrising stem type gate valve 1 keying rotary valve rod, drive the number of turns of screw rod rotation to open and close valve rod completely much smaller than inside screw nonrising stem type gate valve 1 and rotated
The number of turns.
Screw rod 6 can drive sliding shoe 8 to move up and down when rotating, thus driving pointer 14 to move up and down, pointer 14 instruction is opened
Close the graduation mark on degree label 9, thus showing the keying degree of fluid passage.
The pitch of screw rod 6 is less than the pitch of valve rod, and screw rod 6 rotation is turned around, and the distance that sliding shoe 8 moves up and down is less than valve rod
Rotation is turned around and is driven the distance of flashboard up and down motion；
In the case that the fluid passage bore of inside screw nonrising stem type gate valve 1 is certain, rotary valve rod opens and closes to drive during inside screw nonrising stem type gate valve 1 and slides
Block 8 moves up and down apart from also necessarily identical, opens and closes degree by the fluid passage that pointer 14 can be seen that inside screw nonrising stem type gate valve 1.
In the case that the fluid passage bore of inside screw nonrising stem type gate valve 1 is certain, by driving gear 3, the deceleration of driven gear 4 and
The reducing of screw rod 6 pitch, the distance that sliding shoe 8 moves up and down is much smaller than the distance moving up and down when flashboard opens and closes, thus saving
Installing space.
The inside screw nonrising stem type gate valve that this utility model provides opens and closes the display device of degree, and easy and simple to handle, structure is simple, compact, energy
The fluid passage of display inside screw nonrising stem type gate valve directly perceived opens and closes degree, can meet the needs of practical application well.
Embodiment described above only have expressed embodiment of the present utility model, and its description is more concrete and detailed, but simultaneously
Therefore the restriction to this utility model the scope of the claims can not be interpreted as.It should be pointed out that the ordinary skill for this area
For personnel, without departing from the concept of the premise utility, some deformation can also be made and improve, these broadly fall into this
The protection domain of utility model.Therefore, the protection domain of this utility model patent should be defined by claims.
