Description
Izum se odnosi na zaporni zasun sa kućištem zasuna 1 -zapornim klinom pri čemu je zaporni zasun pomičan preko postrano stojećih vodećih veziva duž poprečno na smjer protoka ležećim vodećim žljebovima kućišta zasuna i ima gumeno-elastični omotač kao brtvu. The invention relates to a gate valve with a gate valve housing 1 - locking wedge, wherein the gate valve is movable via side-standing guide fasteners along guide grooves lying transversely to the flow direction of the gate valve housing and has a rubber-elastic casing as a seal.
Do sada. su na aktivirajuće vreteno priključeni zaporni zasuni odn. klinovi za pomicanje pokretanja u području visine vodeni postrance i u području aktivirajućeg vretena, pri čemu na obimu navulkanizirani omotač brtvi klin. Ispostavilo se sada, da. ove vođice klinova zbog opterećenja uzrokuju kosi položaj zapornog klina i time uzrokuju nepovoljne odnose prijenosa sila, što prije svega kod viših vrijednosti aktivnosti dovodi do prijevremenog habanja. Uz to je još nepovoljno, da su gumielastični omotači na kliznim površinama - iz funkcionalno-tehničkih razloga - relativno tankoslojni i kao takvi su također podložni brzom habanju. Osim toga. je zaporno tijelo samo van gumenog omotača podložno koroziji , pri čemu se smanjuje vrijeme trajanja. Until now. are connected to the activating spindle by locking bolts or pins for moving the actuation in the height area are guided laterally and in the area of the actuating spindle, with a vulcanized sheath sealing the pin on the circumference. It turns out now, yes. due to the load, these pin guides cause an oblique position of the locking pin and thus cause unfavorable force transmission relationships, which primarily leads to premature wear at higher activity values. In addition, it is also disadvantageous that the rubber-elastic covers on the sliding surfaces - for functional and technical reasons - are relatively thin-layered and as such are also subject to rapid wear. Besides that. is a sealing body only outside the rubber casing subject to corrosion, which reduces the service life.
Prema EP 0 146 1.12 A predložen je zaporni klin za zaporni zasun koji je radi zaštite od korozije sa svih strana obvijen gumielastičnim omotačem, prema postranom vođenju na užim stranama stvara vodeće žljebove, koji na kućištu čvrstim vodećim letvama klize. Da bi se poboljšala kliznost dodatno se u vodeće žljebove umeće specijalna klizna papuča, zbog čega su potrebne relativno dugi vodeći žljebovi, da bi se postigla odgovarajuća stabilnost potpore /oslonca/. Ni ovdje se ne može na osnovu rasporeda žljebova izbjeći zbog opterećenja kosi položaj klina i habanje ostaje dosta visoko uz to se zbog potrebnih uložaka kliznih papuča, radi prianjanja mora uzeti u obzir još 1 znatno poskupljenje proizvodnje. According to EP 0 146 1.12 A, a locking pin for a locking latch is proposed, which is surrounded by a rubber-elastic coating on all sides to protect against corrosion, creates guide grooves on the narrow sides for lateral guidance, which slide on the housing with solid guide slats. In order to improve sliding, a special sliding shoe is additionally inserted into the guide grooves, which is why relatively long guide grooves are needed, in order to achieve adequate stability of the support. Even here, due to the arrangement of the grooves, the inclined position of the wedge cannot be avoided due to the load, and the wear remains quite high, in addition, due to the necessary inserts of the sliding shoes, for the sake of adhesion, one more significant increase in the production price must be taken into account.
Izumu je zadatak, da izradi zaporni zasun ,koji se uz relativno manji trošak izrade, odlikuje visokom antikorozivnom zaštitom, dobrim klizanjem i prije svega otpornošću na habanje. The task of the invention is to create a locking bolt, which, with a relatively low production cost, is characterized by high anti-corrosion protection, good sliding and, above all, resistance to wear.
Izum rješava ovaj zadatak time da su vodeće spojnice na zapornom klinu, uzeto na njegov smjer pomicanja, u sredini površine i visini projicirane zaporne površine u smjeru protoka na pomičnoj površini raspoređene /zaporne površine zapornog klina/, a omotač zapornog klina na poznati način, stvara zatvoreni zaporni omotač. Kroz - suprotno uobičajenim zapornim klinovima prema dolje smještenim vodećim spojnicama - vođica /klizač/ se postavlja u visini napadne -točke koja rezultira pritiskom klina i time praktički bez više troška sprječava kosi položaj klina. Dovoljan je relativno i usporedno kratko vođenje klina koje svejedno dovodi do izvanredne otpornosti na habanje zapornog sistema. Ravno postavljanje klina u odnosu na vođenje ima kao posljedicu laki hod klizne vođice, jer nema zapinjanja i sl., i time smanjeni momenti opterećenja smanjuju habanje. zatvoreni omotač zapornog klina zaštićuje tijelo klina koji je iz livenog željeza, osobito sfaroliva, siguran od korozije, kojeg je omotač izrađen iz kaučuka koji ima dobra svojstva protiv starenja i otporan je na temperaturu, kao EPDM / etilen-propilen-kaučuk / ili NBR /nitrilkaučuk/. The invention solves this task by the fact that the leading couplings on the stop wedge, taken in the direction of its movement, are arranged in the middle of the surface and at the height of the projected stop surface in the direction of flow on the moving surface /blocking surfaces of the stop wedge/, and the cover of the stop wedge in a known way creates closed barrier envelope. Through - in contrast to the usual locking pins downwardly located guide couplings - the guide /slider/ is placed at the height of the attack point, which results in the pressure of the pin and thus prevents the inclined position of the pin practically without more cost. A relatively and comparatively short guide of the wedge is sufficient, which nevertheless leads to an extraordinary wear resistance of the locking system. The flat placement of the wedge in relation to the guide results in an easy movement of the sliding guide, because there is no jamming, etc., and thus reduced load moments reduce wear. The closed cover of the stop wedge protects the body of the wedge, which is made of cast iron, especially spheroidal, safe from corrosion, whose cover is made of rubber that has good anti-aging properties and is resistant to temperature, such as EPDM / ethylene-propylene-rubber / or NBR / nitrile rubber/.
Da bi se i u području vođenja postigla visoka otpornost na habanje , nataknute su na vodeće spojnice vodeće kapice iz nehabajućeg, na temperaturu otpornog plastičnog materijala, npr. POM /polioksimetilen/, koje sprječavaju prijevremeno habanje o omotača u području vodećih spojnica i po potrebi se mogu jednostavno zamijeniti. In order to achieve high resistance to wear in the guide area as well, guide caps made of non-wearing, temperature-resistant plastic material, e.g. POM /polyoxymethylene/, are placed on the guide connectors, which prevent premature wear on the casing in the area of the guide connectors and can be replaced if necessary. easy to replace.
Na crtežu je predmet izuma pobliže objašnjen i to pokazuju In the drawing, the object of the invention is explained in more detail and they show it

Slika 3 presjek kroz vođicu klina prema liniji III-III slike 1, u povećanom mjerilu Figure 3 section through the wedge guide according to the line III-III of Figure 1, on an enlarged scale
Zaporni zasun 1 obuhvaća kućište zasuna 2 s postavljenim gornjim dijelom 3 kao i iznad jednog u gornjem dijelu 3 pokretno postavljenog aktivirajućeg vretena 4 i posmičnog zapornog klina 5. Ovaj zaporni klin 5 može se pomicati preko aktivirajućeg vretena 4 poprečno na određeni smjer protoka S od strane prolaza 6 kućišta 2, i to od jednog donjeg zapornog položaja /lijeva polovina slike 1 i 2/ u gornji otvoreni položaj,/desna polovina slika 1 i 2/, pri čemu zaporni klin 5 pomoću dviju postranih, odstojećih vodećih spojnica 7, zahvaća u postrane duž smjera pomicanja tekućih vodećih žljebova 8 kućišta zasuna 2. Vodeće spojnice 7 leže pri tome u visini sredine površine M smjera protoka S na pomičnu površinu E projiciranu na površinu F zapornog klina 5, tako da sile pritiska koje djeluju na zaporni klin /sile pritiska protočnog medija/ ne vrše pritisak izokretanja i time nastajući kosi položaj čime se izbjegavaju povišena habanja. The shut-off valve 1 includes a valve housing 2 with a mounted upper part 3 as well as above one in the upper part 3 a movably mounted activating spindle 4 and a sliding locking pin 5. This locking pin 5 can be moved over the activating spindle 4 transversely to a specific flow direction S by passage 6 of housing 2, from one lower locking position /left half of images 1 and 2/ to the upper open position, /right half of images 1 and 2/, whereby the locking pin 5 by means of two lateral, standing guide couplings 7, engages in sideways along the direction of movement of the liquid guide grooves 8 of the valve housing 2. The guide couplings 7 lie at the height of the middle of the surface M of the flow direction S on the moving surface E projected onto the surface F of the stop pin 5, so that the pressure forces acting on the stop pin /pressure forces of the flow medium/ do not exert the pressure of twisting and thus the resulting oblique position, which avoids increased wear.
Za. zaštitu od korozije zaporni je klin 5 proviđen omotačem 9 koji obuhvaća čitano tijelo klina; omotač je od EPDM odn. NER. Dodatno su za poboljšanje svojstava klizanja i za povišenje čvrstoće zaštite od habanja na vodećim spojnicama 7 nataknute klizne kapice 10 iz POMa. For. protection against corrosion is a locking pin 5 provided with a casing 9 that encompasses the read body of the pin; the sheath is made of EPDM or NO R. In addition, sliding caps 10 made of POM are placed on the leading couplings 7 to improve the sliding properties and to increase the strength of the wear protection.
