DVOSEDEŽNI PNEVMATSKI VENTILTWO-SEAT PNEUMATIC VALVE

Predmet izuma je dvosedežni pnevmatski ventil, ki je namenjen usmerjanju pretokov tekočin v prehrambeni industriji in pri katerem je možna vizuelna kontrola mešanja dveh različnih produktov, ki tečeta skozi zgornje oz. spodnje ohišje ventila (križni ali paralelni cevovodi), medtem ko je tudi onemogočeno medsebojno mešanje obeh različnih produktov pri zaprtem ventilu. Izum spada v razreda F16K 1/44 oz. B67C 3/22 mednarodne patentne klasifikacije.The subject of the invention is a two-seat pneumatic valve, which is intended for directing the flow of liquids in the food industry and in which it is possible to visually control the mixing of two different products flowing through the above or lower valve body (cross or parallel pipelines) while also preventing the mixing of the two different products with the valve closed. The invention belongs to classes F16K 1/44 respectively. B67C 3/22 of the International Patent Classification.

-2Tehnični problem, ki ga predložen izum uspešno rešuje je konstrukcija in izvedba takšnega dvosedežnega pnevmatskega ventila, pri katerem bo možno učinkovito čiščenje in ispiranje ventila s sistemom centralnega kemičnega čiščenja, pri čemer naj konstrukcijska rešitev omogoča tudi nadzor nad morebitnim mešanjem obeh produktov, ki nastopa kot posledica okvare na tesnilih dvosedežnega pnevmatskega ventila.-2Technical problem that the present invention successfully solves is the construction and implementation of such a two-seat pneumatic valve, which will allow efficient cleaning and flushing of the valve with a central dry cleaning system, and the design solution should also control the possible mixing of the two products that occur as a result of a failure on the seals of the two-seat pneumatic valve.

Znana rešitev dvosedežnega pnevmatskega ventila, pri katerih je rešen zastavljen tehnični problem čiščenja ventila v dveh taktih je opisana v patentnem dokumentu EP 545 846. Konstrukcijska značilnost opisanega dvosedežnega ventila je izvedena drenažna komora, ki je formirana med dvema cilindričnima deloma ventila, pri čemer je vklopni mehanizem za dvig zgornjega cilindričnega dela izveden tako, da avtomatično naraste zapiralni pritisk na spodnjem cilindričnem delu. Na ta način je možno očistiti s sistemom centralnega kemičnega čiščenja cilindrični del brez bojazni, da bi čistilno sredstvo prehajalo v zgornjo komoro ventila.A known solution for a two-seat pneumatic valve that solves the technical problem of two-stroke valve cleaning is described in patent document EP 545 846. The design feature of the two-seat valve described is a drainage chamber formed between two cylindrical parts of the valve, with the mechanism for raising the upper cylindrical part so as to automatically increase the closing pressure on the lower cylindrical part. In this way, it is possible to clean the cylindrical part with a central dry cleaning system without fear of the cleaning agent passing into the upper chamber of the valve.

Zastavljen tehnični problem rešuje tudi dvosedežni ventil, ki se odpira v treh taktih s pomočjo zgornjega cilindra z vgrajenimi tremi bati. Izvedba je zapletena za izdelavo, poleg tega pa ima razbremenilnik stik z atmosfero.The technical problem is also solved by a two-seater valve that opens in three strokes by means of a top cylinder with three pistons installed. The design is complicated to manufacture, and it also has an atmosphere contactor.

Konstrukcija dvosedežnega pnevmatskega ventila po izumu omogoča učinkovito čiščenje in pranje ventila v treh taktih s pomočjo zgornjega cilindra, v katerem sta nameščena dva bata in spodnjega cilindra z enim batom, ki omogočajo taktno odpiranje spodnje in zgornje ventilne gobe.The construction of the two-seat pneumatic valve according to the invention enables efficient cleaning and washing of the valve in three strokes by means of an upper cylinder, which houses two pistons and a lower cylinder with one piston, which allow the lower and upper valve mushrooms to be opened tactically.

Dvosedežni pnevmatski ventil po izumu bom obrazložil na osnovi izvedbenega primera in pripadajoče slike, ki kaže dvosedežni pnevmatskiThe two-seat pneumatic valve according to the invention will be explained on the basis of an embodiment and the accompanying picture showing a two-seat pneumatic valve

-3ventil po izumu v delnem vzdolžnem prerezu.-3 The valve according to the invention in partial longitudinal section.

Dvosedežni pnevmatski ventil po izumu preprečuje mešanje tekočin med zgornjim ohišjem 1 ventila in spodnjim ohišjem 2 z izvedbo zgornje ventilne gobe 3 in spodnje ventilne gobe 4, v katerih sta nameščeni tesnilki 5 in 6 prednostno v prerezu oblike črke O. V primeru, da pušča katera od navedenih tesnilk 5, 6 teče del tekočine iz zgornjega ohišja 1 ventila ali spodnjega ohišja 2 ventila v medprostor, ki ga pri zaprtem ventilu tvorita obe ventilni gobi 3,4. Iz tega medprostora steče puščajoča tekočina skozi poševne odprtine v spodnji ventilni gobi 4 v votli drog spodnje ventilne gobe 4 na prosto. Pod dvosedežnimi pnevmatski ventil po izumu so nameščene nerjavne posode s samostojnim odtokom. Na ta način lahko servisno osebje takoj tudi vidno določi ventil, ki pušča eno izmed tekočin, medtem ko mešanje tekočin v nobenem primeru ni možno.The two-seat pneumatic valve according to the invention prevents the mixing of liquids between the upper valve body 1 and the lower housing 2 by means of an upper valve sponge 3 and a lower valve sponge 4, in which seals 5 and 6 are preferably provided in the cross section of the O-shape. of the seals 5, 6, a portion of the fluid flows from the upper valve body 1 or the lower valve body 2 into an intermediate space formed by the two valve nozzles when the valve is closed. From this interspace, a leaky fluid flows through oblique openings in the lower valve nozzle 4 into the hollow pole of the lower valve nozzle 4 outdoors. Under the two-seater pneumatic valve according to the invention are installed stainless containers with a separate drain. In this way, service personnel can immediately visibly identify a valve that leaks one of the liquids, while mixing liquids is in no case possible.

Učinkovito pranje sedežev, ventilnih gob ter ohišja ventila je omogočeno z namestitvijo treh pnevmatskih batov, ki v delujejo v določenem zaporedju. Tako v začetnem taktu dvigne bat 9 v spodnjem cilindru 10 spodnjo ventilno gobo 4 tako, da pralna tekočina iz spodnjega ohišja 2 oblije spodnjo ventilno gobo 4, opere medprostor med obema ventilnima gobama 3, 4 in skozi poševne odprtine odteče po votlem drogu spodnje gobe 4 v lovilno posodo in s tem v kanal.Effective washing of seats, valve nozzles and valve body is made possible by installing three pneumatic pistons in a sequence. Thus, in the initial stroke, the piston 9 in the lower cylinder 10 lifts the lower valve nozzle 4 so that the washing liquid from the lower housing 2 pours the lower valve nozzle 4, flushes the space between the two valve nozzles 3, 4 and drains through the hollow poles of the lower nozzle rod 4 into the fishing vessel and thus into the channel.

V naslednjem taktu dvigne bat 7 v zgornjem cilindru 12 zgornjo ventilno gobo 3. Pralna tekočina s tem opere še tesnilo 5. V tretjem taktu porine bat 8 navzgor in s tem odpre ventil. Pralna tekočina tako opere obe ventilni ohišji 1, 2, pri čemer sta ventilni gobi 3, 4 stisnjeni tako, da niIn the next stroke, the piston 7 in the upper cylinder 12 is lifted by the upper valve sponge 3. The washing liquid then rinses the seal 5. In the third stroke, the piston 8 is pushed upwards, thereby opening the valve. The washer fluid is thus washed by both valve housings 1, 2, with the valve nozzles 3, 4 compressed so that there is no

-4iztekanja pralne tekočine v lovilno posodo In od tu v kanal. Pri zapiranju ventila poteka ves proces ravno tako v taktih v obratnem vrstnem redu.-4 Spills of washing liquid into the tray And from here into the channel. When the valve is closed, the entire process is performed in clockwise order.

Razbremenilnik tlačnih udarov, ki je nameščen na dolnjem delu votlega droga spodnje ventilne gobe 4 preprečuje odprtje ventila v primeru močnih hidravličnih udarov in se pere ravno tako preko zunanjih pralnih sistemov, ki perejo po štiri razbremenilne komore naenkrat.The pressure shock exchanger mounted on the lower hollow stem of the lower valve sponge 4 prevents the valve from being opened in the event of severe hydraulic shocks and is also washed through external washing systems, which fire four relief chambers at a time.

Dvosedežni pnevmatski ventil po izumu omogoča z uporabo zgornjega cilindra 11 z dvema batoma in spodnjega cilindra 10 z enim batom taktno odpiranje spodnje ventilne gobe 4 in zgornje ventilne gobe 3. Poleg tega omogoča konstrukcija ventila enostavno tehnično izvedbo spodnjega cilindra 10, ki ga je možno namestiti z dvodelno objemko, medtem ko je zgornji pnevmatski cilinder 11 zaprt z nerjavno žično varovalko.The two-seat pneumatic valve according to the invention enables the tactile opening of the lower valve sponge 4 and the upper valve sponge 3 by the use of the upper cylinder 11 with two pistons and the lower cylinder 10 with one piston 3. In addition, the valve construction allows easy technical installation of the lower cylinder 10, which can be fitted with a two-piece clamp while the upper pneumatic cylinder 11 is closed by a stainless wire fuse.
