SAMOČISTILNI ELEKTROMAGNETNI VENTIL ODVAJALNIKA KONDENZATASELF-CLEANING ELECTROMAGNETIC CONDENSER SENSOR VALVE
Predmet izuma je samočistilni elektromagnetni ventil na napravi za avtomatsko odvajanje kondenzata iz sistema s komprimiranim zrakom ali drugega cevnega in shranjevalnega sistema plina, kjer se izloča kondenzat. V navedenih sistemih se iz plina, predvsem pa iz zraka v sistemih komprimiranega zraka izloča vlaga v obliki kondenzata. Kondenzat s sten cevi in rezervoarjev spira umazanijo, predvsem olja, masti in rjo. Ta umazanija povzroča napake v delovanju znanih ventilov. Sodobni odvajalniki kondenzata so elektronizirani in avtomatizirani, opremljeni so s senzorji, ustrezno elektroniko in krmilniki, ki električno vodijo ventil. Pod oznako »kondenzat« se v nadaljevanju razume izloček tekočine, pomešane z umazanijo in plinskimi mehurčki.The subject of the invention is a self-cleaning solenoid valve on a device for automatic discharge of condensate from a compressed air system or other piping and gas storage system where condensate is discharged. In these systems, moisture in the form of condensate is extracted from the gas, and especially from the air in the compressed air systems. Condensation from the walls of pipes and tanks wash away dirt, especially oils, greases and rust. This dirt causes known valves to malfunction. Modern condensate vents are electronized and automated, equipped with sensors, proper electronics, and controllers that run the valve electrically. The term "condensate" is defined hereafter as the excretion of liquids mixed with dirt and gas bubbles.
Dve najpogostejši izvedbi ventilov sta prikazani na slikah 1 in 2. Na sliki 1 je direktno delujoči elektromagnetni ventil. Kotva 1 je krmiljena s povratno vzmetjo 2 in navitjem 3 elektromagneta. Ko elektronika ugotovi, da so dani pogoji za izpust kondenzata steče tok skozi navitje 3 in elektromagnet odmakne kotvo od ustja 5 odtoka ter s tem odpre iztok kondenzatu. Tok kondenzata je označen s puščicami. Kot je razvidno iz slike 1, je kotva 1 v tlačnem delu ventila, torej v neposrednem stiku s kondenzatom. Ker pa je v kondenzatu umazanija, se ta nabira na stene kotve in ohišja, v katerem se giblje kotva. Sčasoma plast umazanije na stenah kotve in ohišja prepreči gibanje kotve in s tem delovanje ventila. Takšen tip ventila ima lahko tudi kotvo z vzdolžnimi kanali v katerih je kondenzat ki delno, vendar ne zadostno, spira umazanijo s stene kotve in ohišja.The two most common valve designs are shown in Figures 1 and 2. Figure 1 shows a direct-acting solenoid valve. Anchor 1 is controlled by a return spring 2 and a winding 3 electromagnet. When the electronics determine that the given conditions for condensate discharge flow through the winding 3 and the electromagnet moves the corner from the outlet 5 of the drain, thereby opening the condensate outflow. The condensate flow is indicated by arrows. As can be seen from Figure 1, anchor 1 is in the pressure part of the valve, thus in direct contact with the condensate. However, since there is dirt in the condensate, it accumulates on the walls of the anchor and the housing in which the anchor moves. Over time, a layer of dirt on the walls of the anchor and the housing prevents the anchor from moving and thus the valve operates. This type of valve can also have an angle with longitudinal ducts in which the condensate, which partially but not sufficiently, removes the dirt from the wall of the corner and the housing.
Znani ventil po sliki 2 je elektromagnetni membranski servo ventil. Ustje 5 odtoka zapira membrana 6 z vzmetjo 7. Membrana 6 ima majhno luknjo 8 za izenačevanje tlaka. Kotva 1 odpira le povezovalni kanal. Ko so podani pogoji za izpust kondenzata elektromagnet z navitjem 3 pritegne kotvo 4 in sprosti podtlak v prostoru nad membrano 6, ki odpre ustje 5 odtoka. Problem tega ventila je, da ima membrano, ki ima omejeno življenjsko dobo, da umazanija zamaši luknjo 8 in da umazanija blokira gibanje kotve 1.The known valve according to Figure 2 is an electromagnetic diaphragm servo valve. The outlet 5 of the drain is closed by a diaphragm 6 with a spring 7. The diaphragm 6 has a small hole 8 for equalizing pressure. Kotva 1 only opens the connecting channel. When the condensate discharge conditions are given, the solenoid 3 winds up the angle 4 and releases a vacuum in the space above the diaphragm 6 which opens the outlet 5 of the drain. The problem with this valve is that it has a membrane that has a limited life span, that dirt clogs hole 8 and that dirt blocks the movement of anchor 1.
V patentni prijavi DE 10 2008 023 290 Al je prikazana rešitev z membrano s pnevmatskim servosistemom. Pomanjkljivost rešitve je omejena življenska doba membrane, možnost zamašitve tlačnih poti, predvsem pa prikazani ventil ne omogoča električne regulacije.DE 10 2008 023 290 Al discloses a diaphragm solution with a pneumatic servosystem. The disadvantage of the solution is the limited lifetime of the membrane, the possibility of clogging the pressure paths, and above all the valve shown does not allow electrical regulation.
V patentni prijavi EP 1 961 457 A2 je prikazan mehanski ventil, kjer ima gibajoča kotva tesnilne obročke, ki pa so podvrženi mehanski obrabi. Ventil ne omogoča električne regulacije.EP 1 961 457 A2 discloses a mechanical valve where the moving anchors have sealing rings which are subject to mechanical wear. The valve does not allow for electrical control.
-2V patentu US 3,516,430 je prikazan mehanski ventil z membrano. Ventil ne omogoča električne regulacije.-2 U.S. Pat. No. 3,516,430 discloses a diaphragm mechanical valve. The valve does not allow for electrical control.
Pomanjkljivosti znanih ventilov so nezanesljivo delovanje zaradi nanosa umazanije, omejena življenska doba membrane in/ali da ni možna električna regulacija ventila.The disadvantages of the known valves are unreliable operation due to dirt, limited membrane life and / or that no electrical regulation of the valve is possible.
Naloga izuma je konstrukcija takšnega ventila, ki bo ob električni regulaciji imel dolgo življensko dobo, ki mu umazanija ne bo omejevala delovanja in ki bo hkrati konstrukcijsko enostaven.It is an object of the invention to construct such a valve which, when electrically controlled, will have a long service life, which will not be impeded by dirt and which will at the same time be structurally simple.
Po izumu je naloga rešena s samočistilnim ventilom odvajalnika kondenzata po neodvisnem patentnem zahtevku.According to the invention, the problem is solved by a self-cleaning valve of the condensate litter according to an independent claim.

Ventil po izumu je eletromagnetni ventil z gibljivo kotvijo. Ko elektromagnet ni vzbujen, kotva zapira izpust kondenzata, ko pa je elektomagnet vzbujen se kotva odmakne od ustja izpusta in kondenzat lahko izteče. V odvajalnik kondenzata z ventilom po izumu po sliki 3 vstopa kondenzat pod tlakom sistema, katerega kondenzat odvaja, od zgoraj v smeri puščic in se zbira v zbiralniku 31. Z dna zbiralnika 31 vod 32 vodi kondenzat od zgoraj na vstop 35 ohišja 33 ventila. Kondenzat v smeri puščic vstopa v ohišje 35 in zalije kotvo 34 vse do ustja 36. Kotva 34 je v tem izvedbenem primeru v osnovi oblike visokega valja z gornjim in spodnjim čelom, to je osnovno ploskvijo ter plaščem. Razmerje med premerom valja in višino valja je od 1 : 1 do 1: 7. Kotva 34 je gibljivo nameščena v ohišju 33 tako da ima svobodo gibanja gor-dol ter rotacijo. Da kondenzat lahko priteče do ustja 36 ima kotva 34 sredstva za pretok, ki sta v tem izvedbenem primeru vsaj en radialni utor 37 na gornjem čelu kotve 34 in vsaj en vzdolžni utor 38 naThe valve of the invention is an electromagnetic valve with a moving anchor. When the electromagnet is not excited, the angle closes the condensate discharge, but when the electromagnet is excited, the angle moves away from the mouth of the discharge and the condensate may leak. The condensate trap with the valve according to the invention of Figure 3 enters the condensate under pressure from the system, the condensate draining from above in the direction of arrows and collects in the reservoir 31. From the bottom of the reservoir 31, conduits 32 conduct condensate from above to the inlet 35 of the valve body 33. The condensate in the direction of the arrows enters the housing 35 and fills the anchor 34 all the way to the orifice 36. In this embodiment, the anchor 34 is basically the shape of a high cylinder with upper and lower faces, i.e., the base face and the sheath. The ratio of the cylinder diameter to the height of the cylinder is from 1: 1 to 1: 7. Anchor 34 is movably mounted in the housing 33 so that it has the freedom of up and down movement and rotation. In order for the condensate to flow to the mouth 36, the angles 34 have flow means, which in this embodiment are at least one radial groove 37 at the upper face of the angle 34 and at least one longitudinal groove 38 at
-3plašču kotve 34. Utor 37 oziroma več utorov skupaj imajo tolikšen prerez, da omogočajo tolikšen pretok kondenzata, kolikor pretoka omogoča reža med kotvo 34 in ustjem 36. Utor 38 po izvedbenem primeru oziroma več utorov skupaj imajo tolikšen prerez, da skupaj z zračnostjo med kotvo 34 in ohišjem 33 ventila kjer se giblje kotva 34 omogočajo tolikšen pretok kondenzata, kolikor pretoka omogoča reža med kotvo 34 in ustjem 36. Slike od 4.1 do 4.5 prikazujejo detajle kotve 34 z utori 37 in 38. V izvedbenem primeru sta utora 37 in 38 pravokotnega prereza, vendar je prerez utorov lahko tudi drugačne oblike. V spodnjem čelu kotve 34 je vdolbina, v katero je vstavljeno tesnilo 39. Tesnilo 39 je v tem izvedbenem primeru gibljivo po višini kotve 34 in nanj pritiska vzmet 40. V tem izvedbenem primeru je vzmet 40 uporabljena le za pritisk na tesnilo 39. Ob premiku kotve 34 navzdol, to je ko magnet z navitjem 41 popusti, kotva s tesnilom 39 zaradi nadtlaka in gibanja kondenzata močno udari ob ustje 36; vzmet 40 blaži te udarce. Seveda so mogoče tudi drugačne izvedbe uporabe ali neuporabe vzmeti, ki bodo v nadaljevanju opisane. Ko je ventil po izumu in izvedbenem primeru zaprt, kotva 34 s tesnilom 39 nalega na ustje 36. Ko so podani pogoji za izpust kondenzata magnet z navitjem 41 pritegne kotvo 34 navzgor in s tem odpre ustje 36 in omogoči iztok kondenzata. Tok kondenzata ob kotvi 34 izpira umazanijo s sten ohišja 33 in kotve 34 in s tem omogoča nemoteno delovanje vetila.-3 anchor plate 34. The grooves 37 or more grooves together have a cross-section such that they allow as much condensate flow as the gap between the angle 34 and the orifice 36 allows. The groove 38 according to the embodiment or more grooves together has a cross-section such that, together with the gap between the anchor 34 and the valve housing 33 where the anchor moving 34 allow the condensate to flow as much as the gap between the anchor 34 and the orifice 36 allows. Figures 4.1 to 4.5 show the details of the anchor 34 with grooves 37 and 38. In the embodiment, the grooves 37 and 38 a rectangular cross-section, but the cross-section of the grooves may also be of a different shape. In the lower face of anchor 34 there is a recess in which a seal 39 is inserted. In this embodiment, the seal 39 is movable by the height of the angle 34 and pressed by a spring 40. In this embodiment, the spring 40 is used only to press the seal 39. angles 34 down, that is, when the winding magnet 41 loosens, the angles with the gasket 39, due to overpressure and the movement of the condensate, strike strongly at the mouth 36; spring 40 mitigates these impacts. Of course, there may also be different uses or uses of springs that will be described below. When the valve according to the invention and embodiment is closed, an angle 34 with a seal 39 fits into the mouth 36. When the condensate release conditions are given, the winding magnet 41 pulls the angle 34 up, thereby opening the mouth 36 and allowing condensate to flow. The condensate stream at the corner 34 flushes out the dirt from the walls of the housing 33 and the corner 34 and thus allows the uninterrupted operation of the fan.
V izvedbenem primeru je vzmet 40 vpeta med tesnilo 39 in gornji rob kotve 34; mogoče so tudi izvedbe, kjer vzmeti ni ali kjer je vzmet vpeta med tesnilo in ohišje ventila ali pa med kotvo in ohišje ventila.In the embodiment, the spring 40 is fastened between the seal 39 and the upper edge of the angle 34; There may also be embodiments where the spring is not present or where the spring is clamped between the gasket and the valve body or between the angle and the valve body.
Izrazi »gor«, »gornji«, »navzgor«, »zgoraj« pomenijo smer iz katere vteka kondenzat.The terms "up", "upper", "up", "above" mean the direction from which the condensate flows.
Izraz »spodnji« pomeni na strani iztoka kondenzata.The term "lower" means on the condensate outflow side.
V izvedebenem primeru ima kotva sredstva za pretok kondenzata vzdolž plašča. Seveda pa je v okviru izuma mogoča tudi izvedba, kjer je zračnost, torej reža med kotvo in ohišjem ventila kjer se giblje kotva tolikšna, da omogoča pretok kondenzata skozi skozi to režo in so torej sredstva za pretok kondenza vzolž kotve opcijska.In the embodiment, the angular means have means for condensate flow along the sheath. Of course, the invention also provides an embodiment where the gap, i.e. the gap between the anchor and the valve body where the anchor moves, is such that it allows condensate to flow through this slot, and thus the means for condensate flow along the anchor are optional.
Ventil po izumu je mogoče na sistem, ki izloča kondenzat, priključiti tudi neposredno, to je brez zbiralnika in je ohišje ventila pripojeno na sistem neposredno.The valve according to the invention can also be connected directly to the condensate extraction system, ie without the reservoir and the valve body is directly connected to the system.
Konstrukcija ventila po izumu je torej takšna, da sestoji iz zbiralnika, povezanega z ohišjem ventila ali pa je ventil pripojem na sistem neposredno tako, daje vstop kondenzata na nasprotni strani kotve kot je izstop kondenzata. Kotva ima sredstva za pretok kondenzata na enem čelu in opcijsko vzdolž plašča, na drugem čelu pa tesnilo.The construction of the valve according to the invention is, therefore, such that it consists of a reservoir connected to the valve body, or the valve is attached to the system directly in such a way that the inlet of the condensate is opposite the angle such as the outlet of the condensate. The anchor has a means of condensate flow on one face and optionally along the sheath and a seal on the other face.
-4V opisanem izvedbenem primeru je kotva oblike valja in ima najmanj eno čelno radialno in eno vzdolž plašča izvedeno sredstvo za odtok kondenzata. V okviru izuma pa so tudi druge oblike sredstev za odtok kondenzata in druge oblike kotev.-4 In the embodiment described, the cylinder is angular in shape and has at least one front radial and one condensate drain means provided along the sheath. The invention also includes other forms of condensate drainage means and other angular shapes.
Po sliki 6 je čelno odvajalno sredstvo izdelano kot ukrivljen utor, na plašču valja pa je sredstvo za odtok kondenzata izdelano kot utor oblike vijačnice. Po sliki 7 je čelno sredstvo za odtok kondenzata izdelano kot več ukrivljenih utorov tako, da formirajo čelno turbino, na plašču valja pa je sredstvo za odtok kondenzata izdelano kot več utorov oblike vijačnice. V okviru izuma so seveda izvedbe z enim ali več radialnih čelnih utorov in opcijsko z enim ali več vijačnih utorov na plašču, kot seveda tudi z enim ali več ukrivljenih čelnih utorov in opcijsko z enim ali več vzdolžnih utorov na plašču. Prednost ukrivljenih oziroma vijačnih utorov je, da se kotva pod vplivom reakcijske sile iztekajočega kondenzata zavrti in s tem še bolje izpere umazanijo s sten ohišja ventila in s kotve same.According to Figure 6, the front discharge means is made as a curved groove, and on the cylinder sheath, the condensate drain means is made as a helix shaped groove. According to Fig. 7, the condensate outlet face is made as multiple curved grooves to form a front turbine, and on the cylinder sheath, the condensate outlet is made as several helix shaped grooves. The invention, of course, is embodiments with one or more radial front grooves and optionally with one or more helical grooves on the sheath, as well as, of course, with one or more curved front grooves and optionally with one or more longitudinal grooves on the sheath. The advantage of curved or helical grooves is that the anchor is rotated under the influence of the reaction force of the leaking condensate, thus further washing away the dirt from the walls of the valve body and from the anchor itself.
V okviru izuma je tudi možnost, da je le del kondenzata doveden nad kotvo tako, da izpira umazanijo s plašča kotve. Preostali del kondenza pa je doveden pod kotvo neposredno k odtoku pod kotvo.It is also within the scope of the invention that only a portion of the condensate is supplied above the anchor by washing the dirt from the anchor coat. The rest of the condensate is anchored directly to the downstream drain.
Seveda so vse opisane oblike sredstev za odtok kondenzata mogoče tudi na od valja drugačnih oblikah kotev, na primer na kotvah konične oblike. Na slikah 8 in 9 sta prikazani konični kotvi, to je kotvi oblike odsekanega stožca, kjer je kot med radijem osnovne ploskve in vzdolžnico plašča od 0 do 30° . Razmerje med aritmetično sredino premerov spodnje in gornje ploskve odsekanega stožca, to je med gornjim in spodnjim čelom je od 1 : 1 do 1 : 7. Ko elektromagnet pritegne in nato odpusti kotvo se ob stenah kotve in ohišja ventila ustvari tok kondenzata, ki spere umazanijo in je s tem zagotovljeno nemoteno delovanje ventila.Of course, all of the condensate drainage agent shapes described may also be of different angles, such as conical angles. Figures 8 and 9 show the conical angles, that is, the angles of the truncated cone, where the angle between the radius of the base plane and the sheath is 0 to 30 °. The ratio between the arithmetic mean of the diameters of the lower and upper surfaces of the cut cone, that is, between the upper and lower faces, is from 1: 1 to 1: 7. When the electromagnet engages and then releases the angle, a condensate stream is created along the walls of the angle and valve body to wash away the dirt. and this ensures the smooth operation of the valve.
