Description

Magnetic suspension three-ring valve

(1), technical field

The invention belongs to the gate valve series products

(2), background technique

The gate valve series products is of a great variety, has life to use and industrial two big classes.Its basic appearance structure generally all is inverted T-shape, and horizontal line has been represented valve body and the inside sealing system of damming, and vertical line is then represented the sealing system on lever drive axle and the axle; These two all is dynamic seal (packing), and one is with water inlet and the separated sealing of water outlet---as the ceramics of porcelain core valve, the spheroid in the ball core valve, the valve of gate valve etc., can be referred to as guillotine and the sealing of damming; Another then is the Chuan Li Rod spare that removes to drive guillotine in the valve body in order to put in, and it also must both keep sealing with valve body, and is rotatable again; Can be described as the live axle dynamic seal (packing), be called for short driving sealing; In order to prevent that pressure fluid from leaking, the very big pressure that is adjacent to is all executed in these two motive sealings, and this just causes the frictional force of opening/shutting valve very big, and frictional force is big more, and is also big more to the wearing and tearing of Sealing, not only increased external force, and reduced working life; The ball core valve that many diameters are little, will put long Jia Li Rod at valve handle unexpectedly could open and close, and the Strong degree of valve body metal, thickness, weight all will increase greatly, have more than is needed how many times is just bad, not only makes leaked liquid, causes waste, and, increased replacement cost and idle cost.

The motive sealing that is used to dam in this two covers sealing system is absolutely necessary; And Chuan Li Rod spare motive sealing another set of, that be used to drive guillotine, part is many, and the rate of fault height easily leaks, and then can manage cancellation.

For example two identical stator Zhong Clip have three ceramics spools of a moving plate, then can cancel this cover motive sealing system; But deficiency is that its moving plate can not adopt present two-piece porcelain core inclined-plane commonly used to expand flow structure, thereby flow is less; There are a kind of follow-on three ceramics spools to come augmented flow for a slice static seal sheet with the porcelain endless belt, but it has only the single face sealing in fact, thereby sealability is not as the former, these two kinds of spools also have a problem to be, the collar and valve interior wall frictional force that ceramics is installed are bigger, and the valve handle driving structure is fragile; All difficulty is applicable to industrial valve.

For industrial valve, not only require internal dynamic seal solid reliable, also require external energy to bear collision, misoperation, wind and rain, sunlight, vibration or the like rugged environment.The valve core diameter of big-and-middle-sized industrial valve is big, and weight is big, and common porcelain core valve arrangement also is difficult to be competent at; Industry butterfly valve diameter can reach thousands of millimeters, and liquid can surpass tons up to a hundred to its tangent plane thrust; What many industrial valve internals dammed the sealing employing is metal and metal, metal and plastics or plastics and plastics, and their scratch-resistant performances are undesirable; For example the final motive sealing face of butterfly valve is exactly the friction of teflon and teflon usually.Frictional force is big more, driving force is also big, and cost, energy consumption are increased; What accompany with huge frictional force must be the very short life-span.Be used for chemical industry, oil, gas or be used for the valve of water, leak and not only mean waste, also serious environmental problems may appear, produce Xiu Erosion in the liquid in order to prevent to be immersed in for a long time, valve---particularly to live with tap, need a large amount of non-ferrous metals, contain cadmium, lead, the nickel etc. that have are made the cancer things; The annual metallic material that consumes millions of ton of meter of various valves not only costs an arm and a leg, and these metals of smelting Refining have increased CO2 emission again, has polluted environment.Therefore, significantly improve valve working life, improve reliability, reduce weight, also just can reduce metal consumption, raising use value.

People wish to have a kind of firm in structure, sealing is reliable, long service life, driving are light, few with or without non-ferrous metal, acid resistant alkali corrosion, no health and environmental protection worry, price is average, both can be widely used in industrial aspect, also can be widely used in the life aspect, need not throw light at night and also can see, latus rectum is from several millimeters, tens of millimeter, and even thousands of millimeters novel valve.

Purpose of the present invention will solve above variety of problems with " magnetic suspension three-ring valve " exactly.Not seeing in the market has this product, has consulted Chinese patent in recent years, and also not seeing has the innovation structure identical with the present invention.

(3) summary of the invention

A kind of magnetic suspension three-ring valve, comprise the tubular valve body that water intake, water outlet are fused, interior flexible pad and diaphragm seal, its feature such as a kind of magnetic suspension three-ring valve that Fig. 6 gave an example, the outer shroud (1) that it is nested by axis coinciding, ring ring, middle ring (2), interior ring (3), dual sealing (7～13) and magnetic levitation system (19a, the 19b) composition of damming; Internal structure is seen Fig. 2, water intake, cushion (7), static seal sheet (8), motive sealing sheet (9), dynamic elasticity pad (10), motive sealing sheet (11), static seal sheet (12), cushion (13) are the water route with the water outlet order and are connected, Huan Shang And can rotate with interior ring in wherein motive sealing sheet (9), dynamic elasticity pad (10), motive sealing sheet (11) were fixed on, and encircled during all the other are fixed on; On encircling during the outer shroud of band hand-drive or mechanical actuation device is enclosed within, put in interior ring, be mechanical coupling by rigid member with interior ring, also can by be arranged on the outer shroud one or more groups electromagnet or permanent magnet in the electromagnetic driver, see through totally enclosed in ring, be magnetic field or electromagnetic field is connected with electromagnetism driven device on the interior ring; Encircle on the garden side face of inwall during the garden side face of endocyclic outer wall is bearing in, be sliding contact with middle ring, also can be the contact of rolling by roller or the ball that between interior ring and middle ring, is provided with, can also by one on the ring in being fixed on or many permanent magnets, be fixed on the ring one or many permanent magnets, make in ring be magnetic suspension state with middle ring, or use the same method, make outer shroud and middle ring to be magnetic suspension state; On handle, button or the valve body luminous substance is arranged.

Mechanical actuation device on the outer shroud is a handle, also can be gear, worm and gear, laborsaving lever, motor, hydraulic pressure or actuating device of atmospheric pressure; Also comprise steer-drive or self-closing device.

Electromagnet connects with common power on the outer shroud, also can connect with a kind of control circuit that can produce rotating magnetic field or pulsed magnet field.

Electromagnetism driven device on the interior ring is one or more groups permanent magnet or Magnetically Soft Steel or the electromagnet that is wound with short-circuit conductors.

Outer shroud, middle ring, interior ring and static seal sheet, motive sealing sheet can be metallic material, plastics, pottery, glass, silicate material or composite material.

The permanent magnet that constitutes magnetic suspension state in being fixed on ring or the middle ring is to combine by single or many.

Motive sealing sheet on the interior ring is two, also can be one.

In dynamic elasticity pad on the ring constitute by one, also can seal by two rigidity tube walls that constitute, serve as a contrasts in two bullet pads centres, also can perforate and add upper plug head.

Steer-drive or self-closing device constitute by being fixed on gear ring on the outer shroud and the tooth bar that is meshed with it and Returnning spring.

Have on outer shroud and the middle ring rotation positioning and work in coordination draw-in groove and latch, similar rotation positioning and draw-in groove of working in coordination and latch are also arranged on interior ring and the middle ring

Adopt benefit of the present invention to be: a, the live axle of having cancelled present most of in the world classification valves and its dynamic seal (packing), reduced part, reduced rate of fault and leakage, had better mechanical property and water-saving result; B, can open and close with the strength lighter than similar valve, friction is littler, and machinery that big-and-middle-sized valve is used to drive, motor etc. are greatly reduced, and in light weight, less energy consumption, the life-span is long, cost is low; C, the dual sealing of damming have further improved sealability and have prolonged working life; D, the good chemical resistance energy there is, reduces or prevented the poisonous metal element pollution; E, very high versatility is arranged, can be made into the tens of kinds of magnetic suspension three-ring valves of innovating fully that are used for civilian, industrial, agricultural and leading-edge field.

The present invention seeks to realize by the following method: as Fig. 6, Fig. 1, on the macroscopic view, the outer shroud (1) that it is nested by axis coinciding, ring ring, in ring (2), interior ring (3), dual sealing (7～13) and the magnetic levitation system (19a) of damming (19b) form, diaphragm seal (4) then is fixed on the interior ring (3); Different with the T-shape structure of existing valve, it is concentric garden structure basically, and handle puts in the motive sealing of spool have been cancelled.This structural mechanical property is better, part still less, more durable.

Water inlet is flowed out from water outlet, as Fig. 2 at last via water intake, cushion (7), static seal sheet (8), motive sealing sheet (9), dynamic elasticity pad (10), motive sealing sheet (11), static seal sheet (12), cushion (13); Wherein motive sealing sheet (9), dynamic elasticity pad (10), motive sealing sheet (11) be fixed on interior ring (3) Shang And can rotate with interior ring, thus opening/shutting valve; On encircling during all the other two groups of static seal sheets (8) (12) and cushion (7) (13) then are fixed on, they do not rotate, different with other valve is, it is double seal, is that static seal sheet (8), motive sealing sheet (9) have been formed the sealing of first road, motive sealing sheet (11), static seal sheet (12) are then formed the sealing of second road, they all are the sealings of damming, the dual sealing of damming of general name.

Diaphragm seal both can adopt present two-piece porcelain core inclined-plane commonly used to expand flow structure, thereby flow is bigger, has realized double seal again; The double seal benefit is: if one group of diaphragm seal middle part vulnerable zone is former thereby leak because of certain, lose when closing ability, do not influence normally closing of another group diaphragm seal, valve also just can proper functioning, and sealing reliability has also just improved; Also, magnetic suspension or magnetic provides necessary accommodation space for driving; No matter valve opening or close, fluid is limited in diaphragm seal inside by strictness all the time, and fluid does not contact with other position of valve body, just can be less with or without non-ferrous metal, this just is easy to accomplish acid resistant alkali, prevents that poisonous metal such as system cancer things such as Qian, Cadmium, nickel from dissolving in the water, and can prevent Xiu Erosion.And common valve just is difficult to prevent that poisonous metal from dissolving in because metal constructions such as lever drive axle inevitably will contact all the year round with fluid.

Intake-outlet on the middle ring links to each other with the peripheral hardware pipeline with screw thread or flange, also can weld or snap onto in the pipeline; Opinion is not that metal tube or nonmetallic pipe, for example Stainless Steel Tube or plastic-aluminum pipe, PP-R pipe etc. all can connect.

Normally one on dynamic elasticity pad on the interior ring, a dynamic seal (packing) sheet is respectively arranged on its two sides, in pushing vertically, they rotate in the draw-in groove of ring and with interior ring, with this opening/shutting valve, this elastic sealing gasket had both played sealing process, play the effect of compensation sealing pad wear again, make diaphragm seal that longer operating life be arranged; For the normal domestic three-ring valve, the motive sealing sheet adopts one and also is fine, and has not also just had the motive sealing cushion, and only effect is relatively poor, and other has inconvenience.

For the different valve of purposes, outer shroud, middle ring, interior ring and static seal sheet, motive sealing sheet both can be metallic material, plastics, pottery, glass, silicate material, also can be metal and nonmetallic composite material; It is metal that big-and-middle-sized seal spool sheet adopts one side, and another side is nonmetal structure.

When magnetic levitation system or magnetic drive unit are set, often need to do interior ring longer, as shown in Figure 3: the distance between interior ring (3) two the dynamic seal (packing) sheets in two ends (9,11) is bigger, at this moment, will be by two dynamic elasticity pad (10a, 10b) the work of finishing sealing and compensating, when interior ring rotated to closed condition, a diaphragm seal was bearing the pressure of the direction of intaking, another is bearing the pressure of water outlet direction liquid return, and the space between two does not then have pressure; Utilize this Te Dian, can go up perforate (20) by rigidity tube wall (3) betwixt, use plug (21) with its sealing at ordinary times---so-called rigidity tube wall, reality is encircled (3) in being exactly, utilize this perforate, can make valve in pipeline not under the disassembly status, to be in conveyance fluid under the atmospheric pressure state pick up survey, filtration, extraction, injection, temperature adjustment, electrolysis, or the like the physics and chemistry intervention, or valve internal keeped in repair, this is good to big-and-middle-sized valve.

Fig. 1 shows a kind of maglev three-ring valve of not being with, the outer shroud (1) of band hand-drive or mechanical actuation device, be enclosed within on the middle ring (2), put in interior ring, be mechanical coupling by rigid member (5) with interior ring (3), the handle (6) of rotational fixation on outer shroud, ring is followed rotation in just can making by rigid member, sealing ceramics (4) on the interior ring also rotates thereupon, thereby has finished the keying work of valve; Handle can stretch out outer shroud, also outer shroud can be arranged to impeller shape or knob shape.

Outer shroud has not only improved handle bend resistance ability, also plays the effect of Protective valve in-core bilge construction.For medium-sized or large-scale valve, for laborsaving or, can adopt and install gear at outer shroud for the accurate aperture of regulating valve, worm and gear, the labour-saving lever, stepper motor, common electric machine or use hydraulic pressure, pneumatic shuttle comes opening/shutting valve; Stepper motor can constitute accurate flow control system or automatic control system with numerical control device.In order to change the application of force direction of opening/shutting valve, can also steer-drive be set in the outer shroud outside; The main effect of steer-drive is that to make the application of force direction of opening/shutting valve be not garden side face rotation along outer shroud, and is perpendicular to valve core axis or is parallel to valve core axis; For example, the outer garden week of outer shroud is arranged to gear ring, adds a toothed rack and be engaged with, then the push-and-pull tooth bar gets final product opening/shutting valve, and the application of force direction of opening/shutting valve then is vertical with valve core axis, has reached to turn to driving purposes; If on this tooth bar, add a Returnning spring again, valve is at ordinary times by the spring closed condition, promoting tooth bar just opens, then valve has had automatic closing function again, Returnning spring is in the valve body outside, so called after " external Returnning spring ", the self acting stop valve of a kind of band turns to driving that Here it is.

More than this class outer shroud put in by rigid member in ring come the deficiency of opening/shutting valve to be, middle ring does not seal, but it is enough to replace common valve and water tap, comprises pipeline valve, ball core valve, butterfly valve etc.

Require the occasion of high-seal, middle ring complete closed can be got up, by be fixed on permanent magnet or electromagnet on the outer shroud, see through totally enclosed in ring, be electromagnetic field and be connected with electromagnetism driven device on the interior ring; Concrete grammar has three kinds:

1, on outer shroud (1) and interior ring (3), one or more pairs of permanent magnet (14a are set respectively, 14b), make magnet keep the state of attracting each other as figure 4 ， And, like this, as long as the magnet (14a) of rotational fixation on outer shroud, magnet (14b) in will holding through middle ring on the ring makes it to follow rotation, and valve also opens and closes thereupon; Draw-in groove (15) is arranged on the outer shroud, latch (16) is arranged on the middle ring, the angle of swing of ring in limiting with this, thereby the position that ring is gone up diaphragm seal standard-sized sheet full cut-off in limiting; Another kind of scheme is if on encircling in conversely latch being located at, draw-in groove is located on the outer shroud and also is fine; That is to say, as long as rotation positioning and draw-in groove of working in coordination and latch are set on outer shroud and middle ring; On interior ring and the middle ring similar rotation positioning and draw-in groove of working in coordination and latch are set also.

2, outer shroud can replace permanent magnet with electromagnet (18a), as Fig. 5; When static, the spring (17) that draw-in groove (15), latch (16) upward are provided with between inner ring of valve (3) and the middle ring (2) keeps closed condition, and energising produces magnetic force, attracts to be fixed on the magnetic material (18b) on the interior ring, overcomes spring tension and makes opening of valves; Can be draught spring, pressure spring or torque spring---unified is " built-in Returnning spring " with (17) name life; Here it is, and a kind of novel rotating electromagnetic valve---it is different from all reciprocating solenoid valves in the world.

3, adopt the structure of squirrel cage motor: fixing plurality of electromagnetic iron on the outer shroud, the then fixing soft magnetic material of band short-circuit conductors of going up of interior ring is as driven device, like this, when the outer shroud electromagnet adds rotatory current, when producing rotating magnetic field, the induced current of interior ring short-circuit conductors makes the soft magnetic material magnetization and rotates, thereby drives interior ring, opening/shutting valve; Can realize the keying of valve equally with the pulsed magnet field of step-by-step impulse electric current generation.

These three kinds of magnetic or electrically driven (operated) valve can be referred to as magnetoelectricity and drive three-ring valve.Wherein the 2nd, 3 kind of method, during valve opening and closing, on the outer shroud (actual is middle ring outside) without any parts movably, more sturdy and durable; Be particularly suitable for needing the occasion of automatic control, telemechanical or wireless remotecontrol opening/shutting valve, for example in the ocean, that unmanned control station and other have is inflammable, explosive, corruption is touched or the dangerous surface duct of poisoning, colliery pipeline, life in inductive faucet etc.; Compare with the solenoid valve of existing inductive faucet, do not have susceptible to plugging aperture in its runner, rate of fault greatly reduces.

In addition, with this three-ring valve that built-in Returnning spring (17) are arranged of Fig. 5, remove its electromagnetic actuator device (18a) and (18b); Combine with lever drive device shown in Figure 1 again, that is: make valve be closed condition when the static state with the elastic force of spring (17), use the outer shroud (1) of handle (6) to remove to drive the elastic force that interior ring overcomes spring (17) again by rigid member (5), but with regard to Open valve, hand one pine, then close automatically by spring, reach the water saving purpose; Returnning spring can also be located between outer shroud and middle ring or rigid member and the middle ring; This has just constituted a kind of novel three-ring valve of closing automatically.

Frictional force problem about valve internal: on the garden side face of ring inwall, be sliding contact during the garden side face of endocyclic outer wall is bearing in middle ring; Also can make it to be the contact of rolling by roller or the ball that between interior ring and middle ring, is provided with; Ring is magnetic suspension state with middle ring in can also making by the permanent magnet on ring and the middle ring in being fixed on, as Fig. 6.

We know that permanent magnet has the same sex and repels each other, and the performance that there is a natural attraction between the sexes if the permanent magnet of two same polarities is put in attempt together, just produces reverse thrust; As long as the adjacent surface polarity of in making on the ring in being fixed on or many permanent magnets and being fixed on the ring one or many permanent magnets is identical, encircle in just can making and middle ring is magnetic suspension state; As Fig. 6 (9a) or permanent magnet (9b), be by single only or many combine.In like manner, magnetic levitation system is located between outer shroud and the middle ring, ring also was fine in ring went to drive in putting in the rigidity Force transmission parts on the outer shroud again.

Maglev main effect is whole tube wall frictional forces of having eliminated between interior ring and the middle ring, and in hundreds thousand of working life, the friction and the loss of interior ring and middle ring definitely can't neglect at the seal spool sheet; And the wearing and tearing of magnetic suspension zero-friction, nothing; The keying of whole valve is the only friction between remaining valve core inside moving plate and the still just, and in order to seal, degree of finish between the sound sheet has has normally met or exceeded minute surface, frictional force is very little naturally, this just makes the power that drives valve opening and closing very little, the driving mechanism of opening/shutting valve is lighter, energy consumption still less, price is lower; Can also accomplish high-speed opening and closing; Only depend on the wearing and tearing between the sound sheet working life of valve, and this wearing and tearing can just improve overall working life greatly by the cushion compensation! Compare with common ball core valve or gate valve, rough calculation, can improve about ten times of life-spans; This not only can be used for, and ring is from the very big valve of weight in the spool, and the centering valvelet is also very suitable.

The contact of rolling can be used separately with magnetic suspension, also can also can be used in combination.

Because it is very fast that magnetic suspension three-ring valve opens and closes speed, life-span is very long, seals finely, has just opened brand-new gate for its use field one towards electronic digitalizing, for example available it make a kind of pulse digit control valve, be used for the agricultural intelligent water-saving sprinkling irrigation, deinsectization and fertilising etc.

The present invention comprises methodical invention, all structures, comprise tricyclic structure, the material of double sealing structure or magnetic driving, magnetic suspension, electromagnetic actuator device, the shape of part or size all should be decided according to the actual conditions of valve, the figure that not given an example by Fig. 1～Figure 17 limits, but basic skills and principle are identical.

For also opening/shutting valve easily in night or pitch-dark drive, on handle, button or the valve body of three-ring valve, be equiped with luminous substance, it both can indicate the position of valve, hot or cold sense of rotation can also be pointed out to open or close by noctilucence symbol, literal or different fluorescent colours; This when fire causes power failure water detection source of great use.In fact, the noctilucence structure not only can be used for three-ring valve, also can be used for other all valves.

Generally speaking, the invention belongs to the series invention, after adopting the present invention, no matter be the common tricyclic structure of hand-driven, band machinery,, tricyclic structure and magnetic suspension three-ring structure that magnetic drives, and each characteristic combines or respectively the combination diversified novel valve, for example magnetic is driven and the magnetic suspension combination, form magnetic and drive magnetic suspension three-ring valve, magnetic drives the magnetic suspension solenoid valve, various magnetic suspension water nozzles, the magnetic suspension tap, the magnetic suspension flushing valve, the magnetic suspension showering, magnetic suspension nappy tap, magnetic suspension washing machine tap, the magnetic suspension solenoid valve, the magnetic suspension overall diameter throughway valve that replaces overall diameter ball core valve or butterfly valve, magnetic suspension remote-controlled valve and do not want maglev various three-ring valve, three ring taps, three ring overall diameter valves, three ring solenoid valves, the machinery three-ring valve, electronic three-ring valve, pneumatic three-ring valve, automatically close three-ring valve, comprise foot-operated three-ring valve, dozens of kinds such as hand-pulling type three-ring valve, every class can be made into different-diameter again, different profiles, different materials, the thousands of specifications of different purposes.Compare with existing valve, mainly contain five characteristics:

1 has completely abolished at present the easiest live axle that leaks of common valve and its dynamic seal (packing) in the world, and the rate of fault of leakage greatly reduces, has better mechanical property and water-saving result, and has reduced part and cost;

2 owing to cancelled the dynamic seal (packing) that live axle rubber is close to, added structure such as magnetic suspension of the present invention, friction greatly descends, just can open and close with the strength lighter than similar valve, machinery that big-and-middle-sized valve is used to drive, motor etc. are reduced at double, and weight, energy consumption, life-span, cost all have bigger improvement;

The 3 dual sealings of damming have further improved sealing and have prolonged working life;

4 have good chemical resistance energy, minimizing or have cancelled the consumption of non-ferrous metal, reduce or have prevented the poisonous metal element pollution;

5 have very high versatility, can be made into and replace tens of types the valve that is used for civilian, industrial, agricultural and leading-edge field; As common gate valve, porcelain core valve, ball core valve, some butterfly valve etc.; In food, beverage, medicine, water factory, chemical industry, weaving, agricultural, water conservancy, environmental protection, pure water preparation, oil and gas delivery etc. has wide development space.

(5) specific implementation method:

The present invention seeks to realize by the following method: referring to Fig. 1～Figure 17; On the macroscopic view, the outer shroud (1) that it is nested by axis coinciding, ring ring, middle ring (2), interior ring (3), dual sealing (7～13) and the magnetic levitation system (19a) of damming (19b) are formed, and diaphragm seal (4) then is fixed on the interior ring (3); Different with " T " word appearance structure of existing valve, it is concentric garden structure basically.This structural mechanical property is better, and driving part is more durable, and material can be still less.Water inlet is flowed out from water outlet, as Fig. 2 at last via water intake, cushion (7), static seal sheet (8), motive sealing sheet (9), dynamic elasticity pad (10), motive sealing sheet (11), static seal sheet (12), cushion (13); Wherein motive sealing sheet (9), dynamic elasticity pad (10), motive sealing sheet (11) be fixed on interior ring (3) Shang And can rotate with interior ring, thus opening/shutting valve; On the ring, they did not rotate during all the other two groups of static seal sheets (8) (12) and cushion (7) (13) then were fixed on; Intake-outlet on the middle ring links to each other with the peripheral hardware pipeline with screw thread or flange, also can weld or be bonded in the pipeline; For water tap, directly water outlet of water outlet; This motive sealing system both can adopt present two-piece porcelain core inclined-plane commonly used to expand flow structure, thereby flow is bigger, has realized double seal again; Sealing reliability greatly improves; Also, magnetic suspension or magnetic provides necessary accommodation space for driving; No matter valve opening or close, fluid is limited in diaphragm seal inside by strictness all the time, and fluid does not contact with other position of valve body, just can be less with or without non-ferrous metal, this just is easy to accomplish acid resistant alkali, prevents that poisonous metal such as Cadmium, nickel etc. from dissolving in the water, and can prevent Xiu Erosion.

On handle, button or the valve body of three-ring valve, be equiped with luminous substance.

During being bearing in, the garden side face of endocyclic outer wall on the garden side face of ring inwall, is sliding contact with middle ring; Also can be the contact of rolling by roller between ring and the middle ring or ball in being arranged on; Ring is magnetic suspension state with middle ring in can also making by one or more groups permanent magnet that is provided with on ring and the middle ring in being fixed on, as Fig. 6; Maglev main effect is whole tube wall frictional forces of having eliminated between interior ring and the middle ring, the keying of whole valve is the only friction between remaining valve core inside moving plate and the still just, and in order to seal, degree of finish between the sound sheet has has normally met or exceeded minute surface, frictional force is very little naturally, this just makes the power that drives valve opening and closing very little, the driving mechanism of opening/shutting valve is lighter, driving power is littler, energy consumption still less, price is lower; Can also accomplish high-speed opening and closing; Only depend on the wearing and tearing between the sound sheet working life of valve, and this wearing and tearing can compensate by cushion, just improved greatly overall working life, compare with existing ball core valve or gate valve etc., rough calculation, can improve about ten times of life-spans, the driving force of opening/shutting valve then can greatly descend; This not only can be used for, and ring is from the very big valve of weight in the spool, and the centering valvelet is also beneficial.
