Abstract
The utility model is the magnetic force regulating valve without valve rod and movable sealing structure, primarily of valve body, spool, valve gap, interior magnetic rotation rotating disk, outer magnetic rotation rotating disk and the formation such as drive unit and safety cover.Valve body and spool adopt micro-inverted cone to coordinate, and operationally spool slightly does and moves, and makes valve regulated lighter.Inside and outside magnetic rotation rotating disk is all installed with the permanent magnet that magnetic pole is alternately arranged, makes interior magnetic rotation rotating disk and outer magnetic rotation rotating disk at valve gap both sides synchronous axial system by magnetic couple effect, spool rotates the adjustment realized rate-of flow under interior magnetic rotation driven by rotary disc.Owing to eliminating valve rod and movable sealing structure, no longer perforate on valve gap, effectively prevent medium and leaks outside, and can ensure use safety.Be specially adapted to the Flow-rate adjustment of inflammable, explosive, volatile, toxic gas or liquid.With drive unit with the use of rear, the remote regulable control of medium in valve easily can be realized.
Description
Technical field
The utility model relates to a kind of valve, in the hermetically sealed situation without valve rod and movable sealing structure, particularly realize the magnetic force regulating valve that a distant place controls.
Background technique
Valve common is at present all utilize valve rod band movable valve plug (lobe) to rotate or move up and down to realize the control to rate-of flow, and this kind of structure motive sealing maintenance is large, very easily causes medium to leak outside along valve rod; And although the direct action solenoid valve utilizing electromagnetic force to control eliminates the movable sealing structure supporting with valve rod, there is not medium to leak outside, but simply can only realize switching requirements, valve position cannot realize controlled adjustment, and has stricter requirement in installation direction and medium.
Summary of the invention
The utility model provides a kind of magnetic force regulating valve without valve rod and movable sealing structure, to realize the regulable control of rate-of flow.
The utility model solves the technological scheme that its technical problem adopts: without the magnetic force regulating valve of valve rod and movable sealing structure, comprise valve body, spool, valve gap, interior magnetic rotation rotating disk, outer magnetic rotation rotating disk, drive unit and safety cover, it is characterized in that: the spool comprising valve body and be connected with this valve body, spool tightens together with interior magnetic rotation rotating disk, permanent magnet be installed in respectively interior magnetic rotation rotating disk and outer magnetic rotation rotating disk corresponding on position; Rotating shaft is reserved in the bottom of spool and the center portion on interior magnetic rotation rotating disk top, and center portion corresponding with valve body and valve gap is respectively reserved axis hole and is slidably matched; Interior magnetic rotation rotating disk and the fastening rear entirety of spool axis Fang Shangxiang should ensure 0.5-1mm on move scope; The perforate of outer magnetic rotation disk center, is enclosed within bonnet central and reserves outside protruding axle, be slidably matched with cardiac prominence axle in valve gap; Drive unit is fixed on valve gap, and output revolving shaft gear is meshed with outer magnetic rotation rotating disk; Safety cover is arranged on outer magnetic rotation rotating disk and drive unit is outside.。
Outer magnetic rotation rotating disk and interior magnetic rotation rotating disk equal and opposite in direction, magnetic pole logarithm is consistent, respectively the permanent magnet even number that is alternately arranged of insert magnetic pole.Permanent magnet shape is not limit, cylindrical, square, rectangular.What the utility model adopted is 4 pairs of cylindrical permanent magnet.On normal condition lower outside magnetic rotation dish, permanent magnet N pole is extremely corresponding attracting with permanent magnet S on interior magnetic rotation rotating disk, and on outer magnetic rotation rotating disk, permanent magnet S pole is extremely corresponding attracting with permanent magnet N on interior magnetic rotation rotating disk.
Valve body and the micro-inverted cone matching design of spool, when can ensure normally to run, spool slightly floats by pressure medium and outer magnetic rotation rotating disk suction, when rate-of flow adjusts, spool and valve body do not closely cooperate, and freely can rotate, guarantee free adjusting with interior magnetic force rotating disc; When reaching off-position, spool closes spacing restriction by machinery and no longer rotates, and after outer magnetic rotation rotating disk is rotated further several angle, between inside and outside magnetic rotation rotating disk, magnetic force has changed by attraction state state of repelling each other into, interior magnetic rotation rotating disk and spool are slightly moved down, and now spool and valve body closely cooperate and guarantee that valve is tight.If the utility model and solenoid valve with the use of, namely switch is responsible for by solenoid valve, and when the utility model is only responsible for adjust flux, a upper function can not use.
Drive unit is made up of DC micro-motor and train of reduction gears, and during operation, train of reduction gears output gear engages with the outer magnetic rotation rotating disk with external toothing.Can according to the rate request of modulating valve bit switch during manufacture, the train of reduction gears of adapted appropriate speed ratio is with satisfied adjustment requirement.
The all accessories of the utility model, except drive unit and permanent magnet, are the materials processings such as copper, aluminium, stainless steel or engineering plastics and make.
The beneficial effects of the utility model are: after eliminating valve rod and movable sealing structure, valve realizes hermetically sealed, and safety in utilization improves greatly.Be specially adapted to the Flow-rate adjustment of the gases such as inflammable, explosive, volatile, poisonous and harmful or liquid; Distant place real-time control can be realized, easily realize the regulable control of rate-of flow; Not only valve body is hermetically sealed, and control section is also arranged in safety cover, to installation environment strong adaptability, and does not have installation direction to limit.

Embodiment
This embodiment is a kind of magnetic force regulating valve without valve rod and movable sealing structure, as shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8 and Fig. 9, the spool 2 comprising valve body 1 and be connected with this valve body 1, spool 2 tightens together with interior magnetic rotation rotating disk 3, permanent magnet 8 be installed in respectively interior magnetic rotation rotating disk and outer magnetic rotation rotating disk corresponding on position.As shown in Figure 1, rotating shaft is reserved in the bottom of spool 2 and the center portion on interior magnetic rotation rotating disk 3 top, center portion corresponding with valve body 1 and valve gap 4 is respectively reserved axis hole and is slidably matched, guarantee that interior magnetic rotation rotating disk 3 is with during movable valve plug 2 synchronous rotary and lateral shift does not occur, interior magnetic rotation rotating disk 3 and the fastening rear entirety of spool 2 axis Fang Shangxiang should ensure to have an appointment 0.5-1mm on move scope, to guarantee flexible adjustment.After outer magnetic rotation rotating disk 5 center drilling, be enclosed within valve gap 4 center and reserve outside protruding axle, be slidably matched with cardiac prominence axle in valve gap 4.Drive unit 6 is fixed on valve gap 4, and output revolving shaft gear is meshed with outer magnetic rotation rotating disk 5, drives outer magnetic rotation disc spins after receiving command signal.Outer magnetic rotation rotating disk drives magnetic rotation disc spins in valve internal by magnetic couple, and then drives valve core rotation to realize rate-of flow regulable control in valve.
