Description
Technical field
The utility model belongs to valve fittings technical field more particularly to a kind of manual open rod type valve piston operation machine
Structure.
Background technique
The valve containing piston type sealing structure such as double seals butterfly valve, hydroturbine water intake ball valve generally uses driving of surging,
But portioned product considers that cost and engineering characteristic need to drive sealing piston using manual driving device.But manual actuation fills
It is bigger to set the strength that driving sealing piston needs, increases labor intensity of workers, and is frequently necessary to multiple spot output, manipulation is difficult
Degree increases.
Summary of the invention
Place in order to overcome the above-mentioned deficiencies of the prior art, the utility model provide a kind of manual open rod type valve piston behaviour
Make mechanism, structure is simple, and reliable transmission, thrust output is big, reduces labor intensity of workers, and can operate with single-point, uses
Simply.
To achieve the above objectives, the present invention adopts the following technical solutions: a kind of manual open rod type valve piston operation
Mechanism, including upper drive rod, lower drive rod, locking nut, driving nut, support plate and transmission nut, the upper drive rod
One end connect with the valve piston to be driven and is assemblied in valve body, and other end of drive rod is connect with lower drive rod on this, institute
Lower drive rod is stated across valve body and is connected through a screw thread with transmission nut, locking nut is successively arranged outside the transmission nut, is driven
Dynamic nut and support plate, the pipeline that the support plate is connect with valve are affixed.
In the above-mentioned technical solutions, the transmission nut outer surface be equipped with two sections of screw threads, one section be plus thread, end with
The screw thread of locking nut connection is reverse thread.
In the above-mentioned technical solutions, the internal screw thread of the transmission nut is trapezoidal thread.
In the above-mentioned technical solutions, axial gap 2-3mm is equipped between the transmission nut and support plate.
In the above-mentioned technical solutions, the upper drive rod is connect with by attaching nut with valve piston.
The beneficial effects of the utility model are: the operating mechanism structure is simple, reliable transmission；The thrust of output is sufficiently large,
Power transmission is direct, manual operation；Due to being equipped with axial gap between transmission nut and support plate, the device of multiple mechanisms can
It operates to push piston with one cycle, it will not be stuck.
Detailed description of the invention
Fig. 1 is the use structure sectional view of the utility model.
Wherein: 1. valve bodies, 2. pistons, drive rod on 3., 4. lower drive rods, 5. locking nuts, 6. driving nuts, 7. supports
Plate, 8. transmission nuts, 9. butterfly plates.
Specific embodiment
With reference to the accompanying drawing and specific embodiment the utility model is described in further detail.
A kind of manual open rod type valve piston operation mechanism as shown in Figure 1, including upper drive rod 3, lower drive rod 4, lock
Tight nut 5, driving nut 6, support plate 7 and transmission nut 8, one end of the upper drive rod 3 connect with the valve piston 2 to be driven
It connects and is assemblied in valve body 1, other end of drive rod 3 is connect with lower drive rod 4 on this, and the lower drive rod 4 passes through valve body 1 simultaneously
It is connected through a screw thread with transmission nut 8, locking nut 5, driving nut 6 and support plate 7 is successively arranged outside the transmission nut 8,
The pipeline that the support plate 7 is connect with valve 1 is logical to be welded to connect.
In the above-mentioned technical solutions, 8 outer surface of transmission nut is equipped with two sections of screw threads, one connect with driving nut 6
Section is plus thread, and the screw thread that end is connect with locking nut 5 is reverse thread.
In the above-mentioned technical solutions, the internal screw thread of the transmission nut 8 is trapezoidal thread.
In the above-mentioned technical solutions, axial gap 2-3mm is equipped between the transmission nut 8 and support plate 7.
In the above-mentioned technical solutions, the upper drive rod 3 is connect with by attaching nut with valve piston 2.
The operating mechanism rotates clockwise driving nut 6 using tool, passes through locking nut 5 and transmission spiral shell using constantly
The reverse thread of 8 cooperation of mother, prevents driving nut 6 from exiting from transmission nut 8, and driving nut 6 passes through forward screw thread mating band
Dynamic transmission nut 8 rotates together, and rotary torsion is converted into linear thrust and pushes lower drive by the inner trapezoidal thread that transmission nut 8 passes through
Lever 4 is advanced, to push piston 2 and 9 gluing, sealing of butterfly plate.Conversely, rotating counterclockwise driving nut 6, then exits sealing and live
Plug 2.
Due to being provided with axial gap between transmission nut 8 and support plate 7, uniformly distributed several in border when driving piston
Operating mechanism does not have to while operating, and circuiting sequentially each operating mechanism of operation can achieve the purpose that drive piston.
The preferable specific embodiment of the above, only the utility model, but the protection scope of the utility model is not
It is confined to this, anyone skilled in the art within the technical scope disclosed by the utility model, can readily occur in
Change or replacement, should be covered within the scope of the utility model.
