Description

Изобретение относитс к устройствам дл розлива нефтепродуктов и может быть использовано, например, на нефтебазах дл наполнени цистерн светлым нефтепродуктом.The invention relates to devices for dispensing petroleum products and can be used, for example, in oil depots for filling tanks with light oil products.

Известно устройство дл налива нефтепродуктов в железнодорожные цистерны, состо щие из смонтированной с возможностью перемещени по горизонтальным направл ющим тележки и шарнирно укрепленного на ней трубопровода , на одном конце которого имеетс запорна арматура, а на другом - герметизирующа крышка с наливным Насадком, газоотвод щим шлангом и датчиком уровн 13.A device for loading petroleum products into rail tank cars is known, consisting of a trolley mounted on a horizontal rail and a pipeline hinged on it, at one end of which there is a shut-off valve and on the other a sealing cap with a filling nozzle, a venting pipe and level sensor 13.

Недостатком известного устройства вл етс то, что в св зи с различной высотой горловины цистерн датчикопускаетс на различную высоту и поэтому уровень наполнени цистерн различен, что вли ет на точность налива.A disadvantage of the known device is that, due to the different height of the neck of the tanks, the sensor is allowed to different heights and therefore the filling level of the tanks is different, which affects the loading accuracy.

Цель изобретени - порыиение точности при наполнении цистерн различных типоразмеров.The purpose of the invention is precision porying when filling tanks of various sizes.

Поставленна цель достигаетс тем, что устройство, состо щее из смонтированной с возможностью перемещени по горизонтальным направл ющим тележки и шарнирно укрепленного на ней трубопровода, на одном конце которого имеетс запорна арматура, а на другом - герметизирующа крышка с наливным насадком, газоотвод щим шлангом и датчиком уровн , снабжено механизмом фиксации датчика относительно нижнего кра горловины цистерны, содержащим установ10 ленную в герметичной крыиже с возможностью перемещени втулку и расположеннувр в ней штангу с шарнирно укрепленной на ней зубчатой рейкой, при этом на верхнем конце штанги The goal is achieved by the fact that the device consists of a trolley mounted on horizontal guides and a pipeline hinged on it, at one end of which there is a shut-off valve, and on the other - a sealing cap with a filling nozzle, a venting hose and a sensor level, equipped with a sensor fixation mechanism relative to the lower edge of the tank neck, containing a sleeve mounted in an airtight carrier that can be moved and located in it with articulated toothed rack on it, while on the upper end of the rod

15 укреплены руко тка и шарнирно смонтированный на ней подпружиненный фик сатор, соединенный шарнирной т гой с зубчатой рейкой, а датчик уровн установлен на нижнем конце штанги 15 a handle and a spring-loaded locking device hinged on it, connected by a hinge to the rack bar, and the level sensor mounted on the lower end of the rod are strengthened.

20 и имеет кронштейн с поплавковым клапаном .20 and has a bracket with a float valve.

Устройство снабжено установленным на наливном насадке с возможностью перемещени поплавком, соединенным The device is equipped with a float mounted on the filling nozzle with the possibility of movement, connected

25 штоко;1 с установленной на шарнирном трубопроводе заслонкой.25 shtoko; 1 with the valve installed on the hinged pipeline.

Claims

30 in FIG. 3 - the device, side view. The device consists of mounted for movement along the guides 1 of the trolley 2, hinged pipes 3 and 4 mounted on it, fixed on the last counterweight 5, stop valves b installed on the lower end of the pipe 4-fastener 7 with filling nozzle 8 gas exhaust ashang 9 and a level 10 sensor fixed in the fixation mechanism, including a sleeve 11 installed in the lid 7 with a toothed weel 12, a pin 13 located therein, with a hingedly reinforced pinion rack 14, while at the vertical end of the rod 13 are reinforced handle 15 and a spring-loaded clamp 16 pivotally mounted thereon, a sensor 10 on the bottom, at the end of which a bracket 17 and a float 18 with a valve 19 are fixed, and on a filling nozzle 8 a float 20 connected to the valve 21 with a gate 22 is fixed for movement; in a way. Before the start of operation, the pipe 4 finds, with the action of the counterweight 5, in its extreme upper position, so that the needle does not go beyond the gabgrnts of the rolling stock. Valves b and valve 22 are closed, rod 13 with level 10 sensor is located in. extreme lower position. When the tank is fed under the filler neck, it is installed so that it is under the filling nozzle 8. The operator opens the tank lid and in case of inaccurate opening of the EE1 and neck moves the trolley so that the filling nozzle is opposed to the opening. When the pump that supplies oil to the collector 23 is turned on, you simultaneously open the stop valve b and the liquid enters the pipe 4. The operator releases the latch 24 and the pipe 4 under the action of the fluid mass, overcoming the counterbalance moment is lowered into the neck of the tank. The operator has the lock 16, the output of the toothed rack 14 from engagement with the toothed bar 12 and rotates the handle 15 and together with it the rod 13, the sleeve 11 and the sensor 10 so that the bracket 17 goes beyond forming the boiler of the tank. Then the rod 13 is lifted up to the stop of the bracket 17 into the image of a skinny tank. After releasing the latch 16 under the action of the spring 25, the gear rack 14, which engages with the gear strip 12 and is fixed in this position, moves through the rod 26. Since the bracket 17 is installed on the level sensor 10, it is always oriented in a certain position with respect to the upper edge of the generator of the tank. After fixing the level 10 sensor, the operator opens the valve 22. When the liquid level rises, the Float 20 floats to the upper part of the boiler and rotates the handle of the valve 22 through the rod 21, reducing the flow of the product. Upon reaching a predetermined level of liquid, the float 18 rises and opens valve 19. Pressure in the cavity of level 10 sensor is transmitted through hose 27 to the bellows, the contacts open (bellows with contacts not shown), close the conductive stop valve 6, open the air valve 28, and the fluid is drained from the hinge tubes 3 and 4. The operator completely closes the flap 22, presses the locking pin 16, pulling the toothed rack 14 out of engagement with the toothed bar 12, lowers the rod 13 and tightens the handle 15 by 120 °, providing the output of the bracket 1 7 from forming tank. Due to the lack of fluid, the moment from counterweight 5 is greater than that of pipe 4, so it moves to the highest position and is fixed by latch 24. Using the proposed device will allow to obtain a significant economic effect by increasing the accuracy of filling and productivity of labor. Claim 1. Device for loading petroleum products into railway tanks, consisting of a trolley mounted on horizontal trolley and a pipeline hinged on it, at one end of which there is a stop valve, and on the other - a sealing cap with a filling nozzle, a gas outlet hose and a level sensor, characterized in that, in order to increase the accuracy when pouring oil products into tanks of various sizes, it is equipped with a sensor fixing mechanism The lower edge of the neck of the tank contains a sleeve mounted in an airtight lid that can be moved and a rod located in it with a rack pivotally fixed on it, while at the upper end of the rod a handle is attached and pivotally mounted on it with a spring-loaded retainer connected by a hinge pin with gear rack and level sensor mounted on the lower end of the rod

And it has a bracket with a float valve.
