Tehnički problemTechnical problem

Kako konstrukcijski resiti ventil sa permanentnim magnetom koji se otvara dejstvom permanentnog magneta a zatvara ga pritisak fluida iz cevovoda, kako bi se ostvarilo potpuno zaptivanje bez curenja primenom permanentnog magneta? How to structurally solve a valve with a permanent magnet that is opened by the effect of a permanent magnet and closed by the pressure of the fluid from the pipeline, in order to achieve complete sealing without leakage by applying a permanent magnet?

Stanje tehnikeState of the art

Zajedničko za mehaničke ventile je da zatvarač direktno savladava pritisak fluida iz cevovoda, to jest iz dovoda fluida (ventil sa vretenom, kuglom, leptirom). Mehanički ventil sa vretenom (UNITED STATES PATENT, PATENT NUMBER: 4,448,213; 4,736,766; 4,754.950) se zatvara okretanjem vretena, delujući na zatvarač sa zaptivačem aksijalnom silom, da savlada silu kojom fluid iz cevovoda deluje na njega, a otvara okretanjem vretena u suprotnom smeru. Pa dolazi do oštećenja zaptivača oko osovine i zaptivača za zatvaranje. I kod ventila gde zatvarač zatvara odvod fluida, pa je pod pritiskom fluida iz cevovoda, zbog osovine koja izlazi iz kućišta dolazi do oštećenja zaptivača oko osovine. Common to mechanical valves is that the shutter directly overcomes the pressure of the fluid from the pipeline, that is from the fluid supply (valve with stem, ball, butterfly). A mechanical valve with a stem (UNITED STATES PATENT, PATENT NUMBER: 4,448,213; 4,736,766; 4,754,950) is closed by turning the stem, acting on the shutter with an axial force to overcome the force with which the fluid from the pipeline acts on it, and opens by turning the stem in the opposite direction. So there is damage to the seal around the shaft and the seal for the closure. And in the case of the valve, where the closure closes the fluid drain, and is under pressure from the fluid from the pipeline, due to the shaft coming out of the housing, the seal around the shaft is damaged.

Kod servo upravljajućih slavina i ventila ( GB 2103 391A ) magnet 40 se nalazi u ručici 44 i deluje na element 28, na koji deluje i opruga 36. Kod ventila, ručica 44 u kojoj je magnet 40 se klizno pomera po telu 22, u jednom ili drugom smeru, u zavisnosti da li se ventil otvara ili zatvara. Element 28 se nalazi u unutrašnjosti magneta 40, pa zbog polarizacije magneta 40 (polovi na krajevima magneta), kada je element 28 simetričan u odnosu na magnet 40, element 28 "pliva" u magnetnom polju, tj. aksijalna magnetna sila koja deluje na element 28 je nula. In servo-controlled faucets and valves ( GB 2103 391A ), the magnet 40 is located in the handle 44 and acts on the element 28, which is also acted upon by the spring 36. In the case of the valve, the handle 44 in which the magnet 40 is located slides along the body 22, in one or the other direction, depending on whether the valve is opened or closed. The element 28 is located inside the magnet 40, so due to the polarization of the magnet 40 (poles at the ends of the magnet), when the element 28 is symmetrical in relation to the magnet 40, the element 28 "swims" in the magnetic field, i.e. the axial magnetic force acting on element 28 is zero.

Magnet 40 deluje na element 28 aksijalnom magnetnom silom koja savladava silu opruge 36. To znači da element 28 prati pomeranje magneta 40, i time omogućava da se dijafragma 20, sa centralnom rupom 30 i rupacama 26, pod pritiskom dovoda fluida pomera i prati kretanje elementa 28, tj. ventil radi na principu slavine. The magnet 40 acts on the element 28 with an axial magnetic force that overcomes the force of the spring 36. This means that the element 28 follows the movement of the magnet 40, and thus allows the diaphragm 20, with the central hole 30 and holes 26, to move under the pressure of the fluid supply and follow the movement of the element 28, i.e. the valve works on the tap principle.

Kada ventil SI. 5 reguliše nivo akumulisane vode u vodokotliću, nivo akumulisane vode u vodokotliću pomera plovak 144, u kojem je magnet 140. Magnet 140 deluje na element 128 aksijalnom magnetnom silom koja savladava silu opruge 136, i suprotnog je smera od sile opruge 136. To znači da element 128 prati pomeranje magneta 140 i time omogućava da se dijafragma 120, sa centralnom rupom 130 i rupicama 126, pomera i prati kretanje elementa 128. Pa pomeranjem plovaka 144, u kojem je magnet 140, nagore zbog porasta nivoa akumulisane vode, element 128 sa zaptivačem 138 dolazi u položaj da zaptivač 138 dodiruje centralnu rupu 130 na dijafragmi 120 i zatvara je, a kroz rupice 126 prolazi fluid i izjednačava pritisak unutar ventila. A na element 128 i dalje deluje aksijalna magnetna sila magneta 140, koja je suprotnog smera od sile opruge 136, a pomeranja plovaka 144 u kojem je magnet 140 više nema, jer nema porasta nivoa akumulisane vode, pa je zaptivanje je nepotpuno, kao kod mehaničkog ventila sa plovkom. Da bi zaptivanje bilo potpuno, plovak 144 u kojem je magnet 140 trebao bi da nastavi da se pomera do položaja dok aksijalna magnetna sila magneta 140 na element 128 ne bude nula (element 128 simetričan u odnosu na magnet 140). When the SI valve. 5 regulates the level of accumulated water in the cistern, the level of accumulated water in the cistern moves the float 144, in which there is a magnet 140. The magnet 140 acts on the element 128 with an axial magnetic force that overcomes the force of the spring 136, and is in the opposite direction to the force of the spring 136. This means that the element 128 follows the movement of the magnet 140 and thus allows the diaphragm 120, with the central hole 130 and the holes 126, moves and follows the movement of the element 128. So by moving the float 144, in which the magnet 140 is, upwards due to the increase in the level of accumulated water, the element 128 with the seal 138 comes into position so that the seal 138 touches the central hole 130 on the diaphragm 120 and closes it, and the fluid passes through the holes 126 and equalizes the pressure inside the valve. And element 128 is still affected by the axial magnetic force of magnet 140, which is in the opposite direction to the force of spring 136, and the movement of float 144 in which magnet 140 is no longer there, because there is no increase in the level of accumulated water, so the sealing is incomplete, as in the case of a mechanical valve with a float. For the seal to be complete, the float 144 containing the magnet 140 should continue to move until the axial magnetic force of the magnet 140 on the element 128 is zero (the element 128 is symmetrical with respect to the magnet 140).

Ovakvo rešenje ( pronalazak GB 2103 391A ) ventila ima nedostatke kada je u pitanju regulacija nivoa vode, kao u vodokotliću, da osim nepotpunog zaptivanja pri zatvaranju, sa porastom nivoa akumulisane vode, se smanjuje protok dovoda vode ( ventil radi na principu slavine ). This solution (invention GB 2103 391A) of the valve has disadvantages when it comes to regulating the water level, as in a cistern, that apart from incomplete sealing when closing, with an increase in the level of accumulated water, the water supply flow decreases (the valve works on the principle of a faucet).

U predmetnom pronalasku, da bi protok vode kroz ventil sa permanentnim magnetom bio konstantan svo vreme kada je ventil otvoren, i zaptivanje potpuno kada je ventil zatvoren, kretanje klipa pri otvaranju i zatvaranju mora da bude impulsno. Pa su permanentni magneti u gornjem delu ručice, koja je van kućišta, postavljeni paralelno klipu i istoimenim polovima okrenuti prema osi klipa, pa je magnetno polje u centru magneta jednako nuli. S obzirom da su magnetne silnice simetrične osi klipa, permanentni magneti privlače klip aksijalnom magnetnom silom. In the present invention, in order for the flow of water through the permanent magnet valve to be constant all the time the valve is open, and to seal completely when the valve is closed, the opening and closing movement of the piston must be pulsed. Permanent magnets in the upper part of the handle, which is outside the housing, are placed parallel to the piston and the poles of the same name face the axis of the piston, so the magnetic field in the center of the magnet is equal to zero. Since the magnetic fields are symmetrical about the axis of the piston, the permanent magnets attract the piston with an axial magnetic force.

Zbog ovakve polarizacije i položaja magneta u odnosu na klip, samo polovina magneta koja je okrenuta prema klipu, deluje aksijalnom magnetnom silom na klip, pa je kretanje klipa pri otvaranju i zatvaranju impulsno i u suprotnom smeru od kretanja ručice sa magnetom. Due to this polarization and the position of the magnet in relation to the piston, only the half of the magnet that is facing the piston acts with an axial magnetic force on the piston, so the movement of the piston during opening and closing is impulsive and in the opposite direction to the movement of the handle with the magnet.

Pri otvaranju ventila sa permanentnim magnetom, ručicu sa magnetom pomeramo prema klipu, pa u položaju kada magnetna sila, koja aksijalno deluje na klip, savlada dejstvo opruge, klip se pomera prema magnetu i ulazi u sve jače magnetno polje, pa se aksijalna magnetna sila koja deluje na klip povećava, tj. magnet „usisava" klip u svoju unutrašnjost, pa je kretanje klipa impulsno. Znači, dovoljno je dovesti ručicu sa magnetom u položaj u kome magnet inicira proces otvaranja, da bi se proces otvaranja završio sam od sebe. When opening a valve with a permanent magnet, we move the handle with the magnet towards the piston, so in the position when the magnetic force, which acts axially on the piston, overcomes the action of the spring, the piston moves towards the magnet and enters an increasingly strong magnetic field, so the axial magnetic force acting on the piston increases, i.e. the magnet "sucks" the piston into its interior, so the movement of the piston is impulsive. So, it is enough to bring the handle with the magnet to the position where the magnet initiates the opening process, so that the opening process ends by itself.

Pri zatvaranju ventila sa permanentnim magnetom, ručicu sa magnetom pomeramo od klipa, pa u položaju kada aksijalna magnetna sila koja aksijalno deluje na klip oslabi, pa ne može da savlada dejstvo opruge na klip, klip se pod dejstvom opruge pomera od magneta i ulazi u sve slabije magnetno polje, i aksijalna magnetna sila koja deluje na klip se smanjuje, tj. opruga „izbacuje" klip iz unutrašnjosti magneta, pa je kretanje klipa impulsno. Znači dovoljno je dovesti ručicu sa magnetom u položaj u kome magnet inicira proces zatvaranja, da bi se proces zatvaranja završio sam od sebe When closing the valve with a permanent magnet, we move the handle with the magnet away from the piston, so in the position when the axial magnetic force acting axially on the piston weakens, so it cannot overcome the action of the spring on the piston, the piston moves away from the magnet under the action of the spring and enters the increasingly weak magnetic field, and the axial magnetic force acting on the piston decreases, i.e. the spring "ejects" the piston from inside the magnet, so the movement of the piston is impulsive. So it is enough to bring the lever with the magnet to the position where the magnet initiates the closing process, so that the closing process ends by itself.

U predmetnom pronalasku ventil sa permanentim magnetom je "bistabilan", pa je protok vode kroz ventil konstantan svo vreme kada je ventil otvoren, i zaptivanje potpuno kada je ventil zatvoren, bez obzira da li se ručica sa magnetom pomera ručno ili plovkom. In the subject invention, the valve with a permanent magnet is "bistable", so the flow of water through the valve is constant all the time when the valve is open, and the seal is complete when the valve is closed, regardless of whether the handle with the magnet is moved manually or with a float.

Suština pronalaskaThe essence of the invention

Ventil sa permanentnim magnetom je sa klipom. A prema pronalasku klip je unutar kućišta. Permanentni magneti u ručici, koja je van kućišta, postavljeni su paralelno osi klipa, a okrenuti su prema osi istoimenim polovima, da bi mogli da privuku klip koji je unutar kućišta. Pomeranjem ručice aksijalno u odnosu na klip u položaj "OTVORENO", pod dejstvom magnatne sile koja aksijalno deluje na klip vrši se bezkontaktno privlačenje klipa, koji sabija oprugu i otvara ventil. A u položaju "ZATVORENO" magnetne sile permanentnih magneta ne mogu da savladaju silu opruge, pa se zatvaranje vrši dejstvom sile opruge i pritiskom fluida iz cevovoda na klip, da zatvori odvod fluida. The permanent magnet valve is with a piston. And according to the invention, the piston is inside the housing. Permanent magnets in the lever, which is outside the housing, are placed parallel to the axis of the piston, and are turned towards the axis with the same poles, so that they can attract the piston that is inside the housing. By moving the lever axially in relation to the piston to the "OPEN" position, under the influence of magnate force that acts axially on the piston, the piston is attracted contactlessly, which compresses the spring and opens the valve. And in the "CLOSED" position, the magnetic forces of the permanent magnets cannot overcome the force of the spring, so the closing is done by the force of the spring and the pressure of the fluid from the pipeline on the piston, to close the fluid outlet.

Prednosti ovog pronalaska su uglavnom sadržane u činjenicama da klip ne izlazi iz kućišta, pa nema zaptivača oko klipa, i da je klip pod pritiskom opruge i fluida iz cevovoda kada je ventil sa permanentnim magnetom zatvoren, pa je zaptivanje potpuno. The advantages of this invention are mainly contained in the fact that the piston does not come out of the housing, so there is no seal around the piston, and that the piston is under spring and fluid pressure from the pipeline when the permanent magnet valve is closed, so the seal is complete.

Detaljan opis pronalaskaDetailed description of the invention

Slike prikazuju ventil sa permanentnim magnetom, koji se sastoji od kućišta10,16iz dva dela, spojena navojem 14. Ručica 1 u kojoj su permanentni magneti 2 se spaja sa kućištem 16 elastičnom spojnicom 8, koja je eliptičnog poprečnog preseka, u žljebu 13. Pomeranjem ručice 1 iz položaja"OTVORENO"u položaj"ZATVORENO"spojnica 8 se širi u žljebu 13, a u položaju"ZATVORENO"se vraća u prvobitno stanje. Ručica 1 svojom težinom ne može da raširi spojnicu 8 i da pređe u drugi položaj. Uskočnik 15 u žljebu 12 ograničava aksijalno kretanje ručice 1. Permanentni magneti 2 su postavljeni paralelno osi klipa 3 a okrenuti prema osi istoimenim polovima, pa su magnetne silnice simetrične u odnosu na osu klipa 3 SI. 3. S obzirom da su magnetne silnice simetrične osi klipa 3, permanentni magneti 2 privlače klip 3 magnetnom silom koja aksijalno deluje na klip 3. The pictures show a valve with a permanent magnet, which consists of a housing 10, 16 in two parts, connected by a thread 14. The lever 1 in which the permanent magnets 2 are connected to the housing 16 by an elastic coupling 8, which is elliptical in cross-section, in the groove 13. By moving the lever 1 from the "OPEN" position to the "CLOSED" position, the coupling 8 expands in the groove 13, and in to the "CLOSED" position, it returns to its original state. The lever 1 cannot spread the coupling 8 and move to another position due to its weight. The clip 15 in the groove 12 limits the axial movement of the handle 1. The permanent magnets 2 are placed parallel to the axis of the piston 3 and turned towards the axis with the same poles, so the magnetic fields are symmetrical in relation to the axis of the piston 3 SI. 3. Given that the magnetic forces are symmetrical about the axis of the piston 3, the permanent magnets 2 attract the piston 3 with a magnetic force that acts axially on the piston 3.

Zbog ovakve polarizacije magneta 2 (magneti 2 okrenuti istoimenim polovima prema klipu 3) magnetno polje u centru magneta 2 je jednako nuli. Pa zbog polarizacije i položaja magneta 2 u odnosu na klip 3, samo polovina magneta 2 koja je okrenuta prema klipu 3, deluje aksijalnom magnetnom silom na klip 3, pa je kretanje klipa 3 pri otvaranju i zatvaranju u suprotnom smeru od kretanja ručice 1 sa magnetom 2. Due to this polarization of magnet 2 (magnets 2 facing the same poles towards piston 3), the magnetic field in the center of magnet 2 is equal to zero. Well, due to the polarization and position of magnet 2 in relation to piston 3, only the half of magnet 2 that is facing piston 3 acts with an axial magnetic force on piston 3, so the movement of piston 3 during opening and closing is in the opposite direction to the movement of lever 1 with magnet 2.

Pri otvaranju, ručicu 1 sa magnetom 2 pomeramo prema klipu 3, pa kada magnetna sila koja aksijalno deluje na klip 3 savlada dejstvo opruge 4, klip 3 se pomera prema magnetu 2 i ulazi u sve jače magnetno polje, i aksijafia magnetna sila koja deluje na klip 3 se povećava, tj. magnet 2 „usisava" klip 3 u svoju unutrašnjost, pa je kretanje klipa 3 impulsno. When opening, handle 1 with magnet 2 is moved towards piston 3, so when the magnetic force acting axially on piston 3 overcomes the action of spring 4, piston 3 moves towards magnet 2 and enters the stronger magnetic field, and the axial magnetic force acting on piston 3 increases, i.e. magnet 2 "sucks" piston 3 into its interior, so the movement of piston 3 is impulsive.

Pri zatvaranju, ručicu sa magnetom pomeramo od klipa 3, pa kada magnetna sila koja aksijalno deluje na klip 3 oslabi, pa je savlada dejstvo opruge 4, klip 3 se pomera od magneta 2 i ulazi u sve slabije magnetno polje, i aksijalna magnetna sila koja deluje na klip 3 se smanjuje, tj. opruga 4, „izbacuje" klip 3 iz unutrašnjosti magneta 2, pa je kretanje klipa 3 impulsno When closing, we move the handle with the magnet away from the piston 3, so when the magnetic force acting axially on the piston 3 weakens and is overcome by the action of the spring 4, the piston 3 moves away from the magnet 2 and enters the increasingly weak magnetic field, and the axial magnetic force acting on the piston 3 decreases, i.e. spring 4 "ejects" piston 3 from inside magnet 2, so the movement of piston 3 is impulsive

Ventil sa permanentnim magnetom je otvoren, kada se pomeri ručica 1 sa permanentnim magnetima 2 po osi klipa 3 u položaj "OTVORENO" SI. 3. Permanentni magneti 2 privlače klip 3 magnetnom silom koja aksijalno deluje na klip 3, koji sabija oprugu 4, otvara rupu 6, pa fluid iznad membrane 5 ističe kroz rupu 6, a pritisak fluida iznad membrane 5 opada u odnosu na pritisak fluida u cevovodu, pa se membrana 5 podiže pod pritiskom fluida iz cevovoda, i fluid izlazi kroz otvor 9 za odvod fluida The valve with a permanent magnet is opened, when the handle 1 with permanent magnets 2 is moved along the axis of the piston 3 to the position "OPEN" SI. 3. Permanent magnets 2 attract the piston 3 with a magnetic force that acts axially on the piston 3, which compresses the spring 4, opens the hole 6, so the fluid above the membrane 5 flows out through the hole 6, and the pressure of the fluid above the membrane 5 decreases in relation to the pressure of the fluid in the pipeline, so the membrane 5 rises under the pressure of the fluid from the pipeline, and the fluid exits through the opening 9 for draining the fluid

Ventil sa permanentnim magnetom je zatvoren kada se pomeri ručica 1 sa permanentnim magnetima 2 po osi klipa 3 u položaj "ZATVORENO" SI. 3. Magnetne sile permanentnih magneta ne mogu da savladaju silu opruge 4, pa se zatvaranje vrši dejstvom sile opruge 4 i pritiskom fluida iz cevovoda, koji prolazi kroz rupice 7 za izjednačenje pritiska na membrani 5, na klip 3 da zatvori rupu 6 i otvor 9 za odvod fluida, pa je pritisak unutar ventila sa permanentnim magnetom u zatvorenom stanju isti. The valve with a permanent magnet is closed when the handle 1 with permanent magnets 2 is moved along the axis of the piston 3 to the position "CLOSED" SI. 3. The magnetic forces of the permanent magnets cannot overcome the force of the spring 4, so the closing is done by the force of the spring 4 and the pressure of the fluid from the pipeline, which passes through the holes 7 to equalize the pressure on the membrane 5, on the piston 3 to close the hole 6 and the opening 9 for draining the fluid, so the pressure inside the valve with the permanent magnet in the closed state is the same.

U skladu sa idejom pronalaska, klip 3 se nalazi unutar kućišta 10,16 na kome su otvor 9 za odvod fluida i otvor 11 za dovod fluida. In accordance with the idea of the invention, the piston 3 is located inside the housing 10, 16 on which there are the opening 9 for draining the fluid and the opening 11 for supplying the fluid.

U skladu sa željenim ostvarenjem pronalaska, na membrani 5 se nalaze rupice 7 za izjednačenje pritiska, kroz koje prolazi fluid, pa klip 3 kada je ventil sa permanentnim magnetom zatvoren SI. 3, pod dejstvom sile opruge 4 i pritiska fluida iz cevovoda, zatvara rupu 6 na membrani 5 i otvor 9 za odvod fluida, pa je pritisak isti unutar ventila sa permanentnim magnetom u zatvorenom stanju. In accordance with the desired embodiment of the invention, on the membrane 5 there are holes 7 for pressure equalization, through which the fluid passes, and then the piston 3 when the permanent magnet valve is closed SI. 3, under the action of the force of the spring 4 and the pressure of the fluid from the pipeline, closes the hole 6 on the membrane 5 and the opening 9 for draining the fluid, so the pressure is the same inside the valve with a permanent magnet in the closed state.
