Description
Technical field
A kind of spiral closing device and its forced seal ball valve, belong to seal ball-valve technical field.
Background technology
Harsh field is required in field of fluid control, particularly fluid switch control and closing tightness, it is desirable to valve
Door can be as small as possible in the state of straight-through generation pressure drop, and the pressure not influenceed by pipeline pressure medium can be provided
Moment of torsion is sealed, in the prior art, the conventional lift rod-type forced seal ball valve that forced seal valve is represented the most, although the structure
Can realize valve it is contactless with valve seat during the whole major part of switch, without friction, but be not truly realized no friction.
In addition, present applicant proposed a kind of brand-new forced seal ball-valve structure, Patent No. in 2016
201610355492.5, the structure realizes real friction free technical purpose.
In the present invention as stated above, it is real using the top-pressure mechanism between flap and valve seat using the principle of spiral jack-up
Existing folding and closing between flap and valve seat, plays screw thread of the top-pressure mechanism of forced seal between stud gear and flap
Coordinate and realize.Applicant has found that the force of sliding friction produced when being rotated between two screw threads consumes most valves in an experiment
Door operation moment of torsion, valve operation moment of torsion is larger, and machinery driving efficiency is relatively low, for the spiral top pressure mechanism of direct jack-up flap
Efficiency is improved.
The content of the invention
The technical problems to be solved by the invention are：Overcome the deficiencies in the prior art there is provided a kind of valve operation moment of torsion compared with
Spin friction between small, reduction screw thread, life-span of screw thread is extended, lift the spiral closing device of transmission efficiency and its force close
Blocking valve.
The present invention solve its technical problem use technical scheme be：The spiral closing device, it is characterised in that：Including band
There is the active runner of connection boss and with female member of translational, be provided between described active runner and member of translational
Rolling mechanism, rolling mechanism is rotatably on the connection boss of active runner, and rolling mechanism follows active runner together
It may occur from turning while rotation, rolling mechanism is meshed with the internal thread on the inside of member of translational, and active runner passes through roller press
Structure drives member of translational to connect boss outer ring at it and moved axially.
The spiral top pressure part that the spiral closing device of the present invention is directed in forced seal ball valve of the prior art is carried out
Optimal improvements, set up between active runner and member of translational rolling mechanism, and rolling mechanism, which is rotatably arranged on, actively to be turned
On the connection boss of wheel, and it is meshed simultaneously with the internal thread on the inside of member of translational, thus, forms a kind of brand-new transmission side
Formula.I.e. while rolling mechanism is followed and rotated around active runner, simultaneously rotation also occurs for rolling mechanism itself, thus, will be existing
There is the sliding friction in technology to be changed to rolling friction, substantially reduce the friction between screw thread, improve transmission efficiency, so that maximum
The life-span of screw thread is extended to degree, transmission efficiency is improved, operation moment of torsion is reduced.
Described rolling mechanism is borded pile transmission mechanism, borded pile transmission mechanism include multigroup annular be distributed on it is described
The borded pile on boss is connected, connection boss is provided with the positioning hole for installing borded pile, and borded pile two ends are respectively equipped with borded pile

Top and the bottom a, part is smooth annular inner wall, and another part is the annular flank of tooth with internal messing tooth, described borded pile
Provided with the borded pile spline being meshed with the annular flank of tooth.
By setting synchronous ring to ensure that multiple rollers in the uniform position of annular, keep turning for each borded pile all the time
Lift angle of the dynamic phase intervals just with flap internal thread is matched, and keeps roller axis parallel with borded pile Gear axis, while again
The multiple roller synchronous axial systems of energy, so as to ensure the accuracy of mesh between roller and internal and external threads.
It is preferred that, the spiral starting point of borded pile is differed the angle of fixation by every adjacent position that puts in order（In this example
This angle is 30 degree）, it is so fashionable in flap internal thread rotation, it will be engaged successively with all borded piles successively, flap is being screwed in
Do not contacted afterwards with borded pile gear annular connection boss.
Described rolling mechanism is roller mechanism, and roller mechanism includes multigroup annular and is distributed on described connection boss
Roller, roller is the cylinder with a plurality of equidistant annular groove, and the both ends of cylinder are respectively equipped with short axle, connection boss
Provided with the positioning hole for installing roller, roller two ends are rotatably arranged in positioning hole by short axle respectively, and roller passes through annular
Groove is meshed with the internal thread on the inside of the member of translational.
Roller mechanism uses equidistant annular groove so that the screw thread between roller and active runner and member of translational is engaged
Place is changed to roll top pressure from original mutual slip top pressure, during top pressure, by multiple rollers simultaneously, in synchronous relative translation part
The external screw thread of screw thread and active runner is rolled, and then realizes axial translation of the member of translational on active runner.
