Abstract
Uzatvárací ventil paliva je určený na uzatvorenie přívodu paliva z nádrže do vzně tového spatovacieho motora závěsných lokomotiv a tahačov. Pri diatkovom ovládaní vzduchu tento působením na membránou ovládanou tyčkou otvorí spatný ventil a umožní prietok paliva. Možno ho ovládat aj ručnou páčkou, ktorá sa po přívode vzduchu vrátí do původnej polohy.The fuel shut-off valve is intended to be closed fuel supply from tank to vehicle locating engine of overhead locomotives and trucks. With remote control air by acting on the membrane controlled the stick opens the back valve and allows fuel flow. It can also be controlled with a hand lever that comes in after the air supply returns to its original position.
Description
Vynález sa týká uzatváracjeho, ventilu na^ liva určeného pre závěsně lc^drftqtwý $ tá-, hače so vznětovým spalovacím motorům ptaužívané v banskej prevádzke v pro^tr§dí..s nebezpečím výbuchu. 'BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shut-off valve for fuel for use in suspension engines of compression-ignition internal combustion engines used in mining operations in potentially explosive atmospheres. '
Doposiai známe uzatváracie ventily přívodu paliva z nádrže do vznětového spalovacieho motora sú riešené na ovládanie ručně vodičom v motorovom priestore alebo ovládané z kabiny vodiča pákovým a bovdenovým prevodom.The prior art shut-off valves for fuel supply from the tank to the diesel internal combustion engine are designed to be operated manually by the driver in the engine compartment or operated from the driver's cab by a lever and Bowden transmission.
Nevýhodou prvého sposobu je nemožnost urýchleného zastavenia přívodu paliva, například požiari lokomotivy alebo poruche palivového systému. Nevýhodou druhého sposobu je výrobná nákladnost, nízká životnost ovládania v banskom prostředí a problematické použitie pri oddělených kabinách motorovej časti.The disadvantage of the first method is that it is not possible to accelerate the shutdown of the fuel supply, for example a locomotive fire or a fuel system failure. The disadvantage of the second method is the production cost, low operating life in the mining environment and problematic use in separate cabins of the engine part.
Nevýhody doposiat známých riešení tohoto druhu sú odstránené uzatváracím ventilom paliva podta vynálezu, podstata ktorého spočívá v tom, že v ose telesa umiestnená ovládaná tyčka má zo strany spatného ventilu osadenie a na druhej straně membránový tanier, na ktorý sa opiera membrána diatkového vzduchového ovládania, pričom ovládacia tyčka má v strednej časti vybranie, do ktorého zapadá excentricky výstupok ručně ovládanej páčky.Disadvantages of hitherto known solutions of this kind are eliminated by the fuel shut-off valve according to the invention, characterized in that the control rod placed in the axis of the body has a shoulder on the side of the rear valve and a diaphragm plate on which the diaphragm air control membrane rests. the control rod has a recess in the central part, which fits eccentrically the projection of the manually operated lever.
Podstatou je tiež, že ovládacia páčka je na konci ramena opatřená závažím, pričom pri najvyššej polohe excentrického výstupku a otvorenom spatnom ventile je závažie v polohe kolmej na osu ovládanej tyčky.It is also a feature that the control lever is provided with a weight at the end of the arm, with the weight in the position perpendicular to the axis of the rod to be operated at the highest position of the eccentric protrusion and the inverted valve open.
Nový a vyšší účinok uzatváracieho ventilu podta vynálezu je najma v tom, že je umožnené diatkové ovládanie z kabiny, resp. núdzovo ručnou páčkou z motorovej časti. Novost je tiež v tom, že ručné otvorenie ventila sa samo zruší prívodom tlakového vzduchu pri dialkovom ovládaní z kabiny. Výhodou riešenia je tiež skutočnosť, že pri poruche přívodu tlakového vzduchu diatkového ovládania ostává ventil uzatvorený, čo je důležité z htadiska bezpečnosti, napr. pri požiari. Umožněné je tiež jeho napojenie na blokovaciu automatiku lokomotivy.The novel and higher effect of the shut-off valve according to the invention is particularly the fact that it is possible to control the remote from the cockpit resp. emergency hand lever from engine part. A novelty is also that the manual opening of the valve is canceled by the supply of compressed air for remote control from the cab. The advantage of the solution is also that in case of failure of the compressed air supply of the remote control, the valve remains closed, which is important from the point of view of safety, e.g. in the fire. It is also possible to connect it to the locking automatics of the locomotive.
\ | ^Na pripojenom výkrese jé*příkladné vyhotovenťe ůzátyáíraciafto ventilu paliva. Na * obr. je fez; veAtilom V uzatvorenej polohe. ř s Uz^tvgrac^ yeptil paliva pozostáva z telesa 'ventilu *1,’ ktoré je dvojdielne. V hornej časti telesa 1 je uložený spatný ventil 2 s kuželkou 2.1 a pružinou 2.2. V ose telesa ventilu 1 je ďalej uložená ovládaná tyčka 3 majúca osadenie 3.1, vybranie 3.3 ukončená membránovým tanierom 3.2 s pružinou 9. Utěsněná je tesniacim krúžkom 8. O membránový tanier 3.2 sa opiera membrána 5, ktorá je v telese ventila 1 upevněná vekom 6 a skrutkami 10. Veko 6 má vybranie 6.1 pře membránu 5 s membránovým tanierom 3.2 a otvor na přívod tlakového vzduchu 6.2. Z boku je v telese ventilu 1 uložená ovládacia páčka 4, opatřená excentrickým výstupkom 4.1 a závažím 4.2 zaistená je vidličkou 11.\ | In the accompanying drawing, there are exemplary embodiments of a fuel valve. In FIG. je fez ; in the closed position. The fuel gripper consists of a valve body 1, which is two-piece. In the upper part of the body 1 there is a valve 2 with a plug 2.1 and a spring 2.2. In the axis of the valve body 1, there is also a control rod 3 having a shoulder 3.1, a recess 3.3 terminated by a diaphragm plate 3.2 with a spring 9. The sealing ring 8 is sealed against the diaphragm plate 3.2. The cover 6 has a recess 6.1 for the diaphragm 5 with the diaphragm plate 3.2 and a compressed air supply opening 6.2. The control lever 4 is mounted on the side of the valve body 1, provided with an eccentric projection 4.1 and a weight 4.2 secured by a fork 11.
V základnej kludovej polohe je uzatvárací ventil zatvorený. Prietok paliva v smere šipky 1.1 cez spatný ventil 2 je znemožněný kuželkou 2.1, ktorú do sedla pritláča pružina 2.2 a tlak paliva.In the basic idle position, the shut-off valve is closed. The flow of fuel in the direction of the arrow 1.1 through the inlet valve 2 is prevented by the plug 2.1, which is pressed into the seat by the spring 2.2 and the fuel pressure.
Prívodom tlakového vzduchu cez přívod vzduchu 6.2 pod membránu 5 tento tlakom na membránový tanier 3.2 zodvihne ovládaciu tyčku 3, a to osadením 3.1 kuželku 2.1 zo sedla a umožní prietok paliva ventilom v smere šipiek 1.1. Poklesom tlaku vzduchu sa uzatvárací ventil uzatvorí. V případe, že v obvode lokomotivy nie je vzduch možno ventil otvoriť núdzovo ovládacou páčkou 4 vychýlením o 90° do vodorovnej polohy. Excentrický výstupok 4.1 ovládacej páčky 4 působením na vybranie 3.3 ovládacej tyčky ju zodvihne a otvorí prietok paliva cez spatný ventil 2. Prívodom tlakového vzduchu sa ovládacia páčka 4 uvolní, závažie 4.2 ju vráti do východzej polohy.By supplying compressed air through the air inlet 6.2 below the diaphragm 5, this pressures the diaphragm plate 3.2 by lifting the control rod 3 by mounting 3.1 of the plug 2.1 from the seat and allowing fuel to flow through the valve in the direction of arrows 1.1. As the air pressure drops, the shut-off valve closes. In the event that there is no air in the locomotive circuit, the valve can be opened by the emergency control lever 4 by tilting by 90 ° to the horizontal position. The eccentric projection 4.1 of the control lever 4, acting on the recess 3.3 of the control rod, lifts it and opens the fuel flow through the inlet valve 2. The pressure lever releases the control lever 4, the weight 4.2 returns it to its initial position.
Uzatvárací ventil možno použit s výhodou aj u iných zariadení, kde je žiadúce, aby pri přívode ovládacieho média sa přívod paliva uzavřel.The shut-off valve may also be advantageously used in other devices where it is desirable to close the fuel supply when the control medium is supplied.
