Oblasť technikyTechnical field
Vynález sa týka veka spojovacieho článku potrubných systémov, ktoré je opatrené nátrubkom na vstup kvapaliny a výstup kvapaliny, pričom v telese spojovacieho článku je otvor slúžiaci na umiestnenie prietokomeru (počítadla prietokového množstva kvapaliny).The present invention relates to a cover member of a piping system which is provided with a fluid inlet and a fluid outlet, wherein there is an opening in the body of the connecting member for accommodating a flow meter (fluid flow meter).
Doterajší stav technikyBACKGROUND OF THE INVENTION
V potrubných systémoch slúžiacich na zásobovanie vodou alebo na obeh výhrevného média v budovách sa spravidla používajú prietokomery, ktorými sa zachytáva spotreba vody alebo výhrevného média. Tieto prietokomery sa montujú do spojovacích článkov zaradených do potrubného systému; spojovacie články majú prípoje, ktorými kvapalina do systému vstupuje a vystupuje. Počítadlo, resp. prietokomer sa zaskrutkuje do otvoru v telese spojovacieho článku, obyčajne v polohe kolmej na os príslušného úseku potrubia. V spojovacom článku môžu byť okrem toho vytvorené navádzače toku kvapaliny, aby sa dosiahol požadovaný prítok kvapaliny do prietokomera.In piping systems used to supply water or circulate a heating medium in buildings, flow meters are typically used to capture the consumption of water or the heating medium. These flowmeters shall be mounted in the couplings included in the piping system; the couplers have connections through which liquid enters and exits the system. Counter, resp. The flow meter is screwed into a bore in the coupling body, usually at a position perpendicular to the axis of the pipe section in question. In addition, fluid flow guides may be provided in the connection member to achieve the desired fluid flow into the flow meter.
Pri montáži takýchto zariadení alebo pri údržbárskych prácach sa však často vytvárajú drobné kovové stružliny, ktoré zostávajú v obehovom systéme a ktoré výhrevné médium unáša so sebou. Tieto stružliny sa z obehového systému dajú odstrániť iba pomerne nákladným spôsobom a tým, že preniknú do meracieho systému prietokomera môžu viesť k poruchám alebo dokonca k poškodeniu prietokomerov.However, in the installation of such devices or during maintenance work, tiny metal shavings are often formed which remain in the circulatory system and which carry the heating medium with them. These shavings can only be removed from the circulatory system in a relatively costly manner, and by penetrating the flow meter measuring system they can lead to malfunctions or even damage to the flow meters.
Vo vodovodných potrubiach, pri ktorých sa používajú zapuzdrené prietokomery, sa na odstraňovanie stružlín alebo splodín korózie z potrubia namiesto zapuzdreného prietokomera do otvoru spojovacieho článku vkladá zaslepovacie veko a voda sa nechá odtekať cez kohútik otvorený naplno. Týmto spôsobom sa majú z vodovodného systému vyplaviť nečistoty.In water pipelines where encapsulated flowmeters are used, instead of encapsulated flowmeters, a blanking cap is inserted into the connection hole of the connecting element to remove cracks or fumes of corrosion from the pipe, and the water is drained through the tap open fully. In this way, impurities should be washed out of the water system.
31867/T31867 / T
Odhliadnuc od toho, že sa tým zväčší spotreba vody, musí sa po vyplavení nečistôt odmontovať a prečistiť perlátor kohútika, čo opäť predstavuje prídavné náklady.Apart from the increased water consumption, the faucet aerator must be removed and cleaned after the impurities have been washed out, which again constitutes an additional cost.
Úlohou predmetného vynálezu preto je odstrániť nečistoty z potrubných systémov jednoduchším spôsobom.It is therefore an object of the present invention to remove impurities from piping systems in a simpler manner.
Podstata vynálezuSUMMARY OF THE INVENTION
Podlá vynálezu túto úlohu v podstate rieši veko s nátrubkom, ktorý zasahuje do otvoru telesa článku a ktorý slúži na usmernenie toku kvapaliny, pričom v tomto nátrubku je umiestnený filtračný prvok. Takéto veko sa vkladá do spojovacieho článku namiesto prietokomera vody, resp. výhrevného média, pričom kvapalina pretekajúca potrubím prechádza cez filtračný prvok. V ňom sa nežiadúce.stružliny alebo iné nečistoty zachytia a možno ich vybrať spolu s vekom. Keďže spomínané nečistoty sa už do ďalších úsekov potrubia neprenášajú, zabráni sa tým vo vykurovacích zariadeniach výpadku meračov spotreby tepla (spôsobeného znečistením) a odpadne čistenie perlátorov na kohútikoch vodovodných potrubí.According to the invention, this object is essentially achieved by a lid with a nozzle which extends into the opening of the cell body and which serves to direct the flow of the liquid, in which the filter element is arranged. Such a lid is inserted into the coupling instead of the water flow meter or the water meter. the liquid flowing through the conduit passing through the filter element. The jaws or other impurities are trapped in it and can be removed with age. Since these impurities are no longer transferred to other pipe sections, the heat consumption meters (caused by contamination) are prevented in heating systems and the aerators are not cleaned at the taps of the water pipes.
Podľa výhodného usporiadania predmetu vynálezu prilieha nátrubok na tesniacu plochu spojovacieho článku a oddeľuje vstup kvapaliny od výstupu kvapaliny, takže celý tok kvapaliny prechádza cez filtračný prvok.According to a preferred embodiment of the invention, the sleeve adjoins the sealing surface of the connecting member and separates the liquid inlet from the liquid outlet so that the entire liquid flow passes through the filter element.
Je výhodné, ak filtračný prvok tvorí spolu s nátrubkom jeden kus, takže ho bez ďalších montážnych úkonov možno spolu s vekom vložiť do spojovacieho článku.It is advantageous if the filter element forms one piece together with the sleeve so that it can be inserted into the connecting element together with the lid without further assembly operations.
Podľa osobitne výhodného usporiadania predmetu vynálezu je filtračným prvkom sito spoľahlivo zachytávajúce nečistoty, ktoré sa v potrubiach obyčajne vyskytujú. Keď sa veko zo spojovacieho článku vyberie, dajú sa nečistoty z veka jednoducho vypláchnuť.According to a particularly preferred embodiment of the present invention, the filter element is a screen that reliably retains the dirt that is typically present in the piping. When the lid is removed from the link, the dirt can easily be flushed out of the lid.
31867ZT31867ZT
Ak sa okolo sita vytvorí valcovitá bariéra, zabráni sa tým pri vyberaní veka so sitom vypadávaniu stružlín alebo iných nečistôt.If a cylindrical barrier is formed around the screen, it will prevent shedding or other contaminants from falling out when the screen lid is removed.
Podľa predmetného vynálezu má nátrubok aspoň jeden otvor pre vstup kvapaliny a aspoň jeden otvor pre výstup kvapaliny, takže sa dosiahne definované usmernenie prúdenia kvapaliny.According to the present invention, the sleeve has at least one liquid inlet and at least one liquid outlet so that a defined flow direction of the liquid is achieved.
Je výhodné, ak nátrubok má tvar valca, pričom otvor pre vstup kvapaliny je usporiadaný radiálne a otvor pre výstup kvapaliny je usporiadaný axiálne, alebo opačne. Celkové usporiadanie nátrubku môže pritom byť prispôsobené tvaru spojovacieho článku tak, aby sa dosiahlo požadované nasmerovanie prítoku kvapaliny do prietokomera.Advantageously, the sleeve is cylindrical, with the liquid inlet opening arranged radially and the liquid outlet opening arranged axially or vice versa. The overall configuration of the nozzle can be adapted to the shape of the coupling so that the desired flow of the liquid into the flowmeter is achieved.

Príklad uskutočnenia vynálezuDETAILED DESCRIPTION OF THE INVENTION
V potrubných systémoch zásobovania vodou alebo v systémoch obehu výhrevného média v budovách sa používa spojovací článok 1. s nátrubkami 2, 3 slúžiacimi na spájanie s potrubím a na vstup, resp. výstup kvapaliny. V polohe v podstate kolmej na nátrubky 2, 3 sa nachádza hrdlo 4 spojovacieho článku, v ktorom je vytvorený otvor 5 spojovacieho článku určený na vloženie prietokomera vody, resp. výhrevného média. Spojovací článok 1_ má navádzacie plochy 6 slúžiace na usmernenie toku kvapaliny a výstupný, vIn piping systems for water supply or in systems for circulating heating medium in buildings, a connecting element 1 is used with pipes 2, 3 for connection to the piping and for the inlet and outlet respectively. liquid outlet. In the position substantially perpendicular to the sleeves 2, 3 there is a neck 4 of the connecting link, in which the opening 5 of the connecting link is provided for receiving the water flow meter or the water flow meter. heating medium. The connecting member 7 has guide surfaces 6 serving to direct the flow of liquid and an outlet v
31867/T podstate centrálne umiestnený (a na obrázku zvisle znázornený) otvor 7, ktorý prechádza do nátrubku 3 pre výstup kvapaliny. Navádzacie plochy 6 a výstupný otvor 7 sú prispôsobené požiadavkám tvaru prietokomera (ktorý nie je na obrázku znázornený) a majú zabezpečiť definovaný prívod kvapaliny k prietokomeru alebo jej odvádzanie od prietokomera. Ak je pre daný prietokomer potrebný iný priebeh toku kvapaliny, môže byť spojovací článok vytvarovaný aj inak.31867 / T substantially centrally located (and shown vertically in the figure) aperture 7, which passes into the fluid exit sleeve 3. The guide surfaces 6 and the outlet opening 7 are adapted to the requirements of the shape of the flow meter (not shown in the figure) and are intended to provide a defined liquid supply to or from the flow meter. If a different flow of liquid is required for a given flow meter, the connecting member may also be shaped differently.
Na tento spojovací článok 1, ktorý sa spravidla zaraďuje do potrubia inštalovaného pod omietkou, sa podľa predmetného vynálezu nasadzuje veko 8, ktoré sa spojením pomocou závitu alebo západiek vloží a upevní do otvoru 5 spojovacieho článku. Na vnútornej strane veka 8 sa nachádza nátrubok 9, ktorý má vo svojej, v podstate valcovitej stene 10 radiálne vstupné otvory 11, 12 na prietok kvapaliny. Na dne nátrubku 9 ležiacom oproti veku 8 sa nachádza filtračný prvok 13, ktorý má tvar sita s väčším počtom prietokových otvorov 14. Vonkajšiu stranu sita 13 obopína tesniaci prstenec 15, ktorý tesne prilieha na tesniacu plochu 1_6 spojovacieho článku 1. Sito 13 vytvára spolu s nátrubkom 9 jeden kus a je pevne zalisované do tesniaceho prstenca 15. Medzi sitom 1_3 a vstupnými otvormi 11, 12 je stena 10 nátrubku 9 vytvarovaná ako bariéra 17. Nátrubok 9 je pomocou západky alebo podobným spôsobom pevne spojený s vekom 8. Veko 8 má na svojej vonkajšej strane výstupok 1_8, ktorý môže byť napr. šesťhranný a na ktorý sa pri montáži nasadzuje príslušný nástroj. Veko 8 je na hrdle 4 spojovacieho článku 1 utesnené pomocou tesnenia 19, napr. pomocou O-krúžku.The connector 1, which is generally inserted into a flush-mounted conduit, is provided with a cover 8 according to the invention, which is inserted by means of a thread or latch connection and fixed in the opening 5 of the connector. On the inside of the lid 8 there is a sleeve 9 which has in its substantially cylindrical wall 10 radial inlet openings 11, 12 for the liquid flow. On the bottom of the sleeve 9 opposite the lid 8 there is a filter element 13 having a sieve shape with a plurality of flow openings 14. The outer side of the sieve 13 is encircled by a sealing ring 15 which fits tightly to the sealing surface 16 of the connecting link 1. Between the screen 13 and the inlet openings 11, 12, the wall 10 of the sleeve 9 is shaped as a barrier 17. The sleeve 9 is rigidly connected to the lid 8 by means of a latch or similar means. a projection 18 which may be e.g. hexagonal and on which the corresponding tool is mounted. The lid 8 is sealed to the neck 4 of the link 1 by means of a seal 19, e.g. using the O-ring.
Podľa predmetného vynálezu veko 8 s pevne pripojeným nátrubkom 9 sa pred uvedením vykurovacieho zariadenia do prevádzky, resp. pri preplachovaní vodovodného potrubia nasadí do hrdla 4 spojovacieho článku namiesto prietokomera vody alebo výhrevného média. Ak potom kvapalina preteká cez spojovací článok 1, zachytávajú sa stružliny alebo iné nečistoty unášané kvapalinou na site 13 a možno ich spolu s vekom 8 vybrať zo spojovacieho článku 1. Bariéra V7, ktorá obklopuje sito, zabraňuje vypadávaniuIn accordance with the present invention, the cover 8 with the fixed socket 9 is switched off before the heating device is put into operation. when flushing the water pipe, instead of using a water or heating medium flow meter, it fits into the connection neck 4. If the liquid then flows through the coupling 1, the cracks or other impurities entrained by the liquid on the sieve 13 are trapped and can be removed together with the lid 8 from the coupling 1. The barrier V7, which surrounds the sieve, prevents falling out
31867/T čiastočiek nečistôt, čím sa zabezpečí spoľahlivé odstraňovanie znečisťujúcich látok. Veko 8 s nátrubkom 9 sa potom dá bez ťažkostí vypláchnuť a vyčistiť. Z obehového systému výhrevného média, resp. z vodovodného potrubia sa takto nečistoty spoľahlivo odstránia. Zvýšené náklady na montážne práce tu nevznikajú, pretože všetky pracovné úkony v teréne sú rovnaké ako pri bežnom uvádzaní zariadenia do prevádzky, resp. pri prečisťovaní potrubia. Pritom odpadá následné čistenie perlátorov, ktoré by inak bolo potrebné vtedy, keď sa vodovodné potrubia čistia preplachovaním.31867 / T dirt particles to ensure reliable pollutant removal. The cap 8 with the nozzle 9 can then be flushed and cleaned without difficulty. From the circulation system of the heating medium, resp. dirt is reliably removed from the water pipe. Increased assembly costs do not arise here, since all field operations are the same as during normal commissioning of the system. when cleaning the pipe. There is no need to clean the aerators, which would otherwise be necessary if the water pipes are flushed.
