PRODUCTS IN TRANSPORT CAPACITIES, containing articulated joints of the product pipeline, a co-discharge (Put.f pipe line with a pneumatic level limit sensor, including a vertically positioned branch pipe, H is a gas flow recorder connected to a shut-off valve, It is distinguished by the fact that, in order to increase reliability of work, it is equipped with a camera divided by a vertical partition, not reaching its bottom, into two sections and having a shunting hole in the side wall The nozzle of the limit sensor is communicated with the vapor pipe through the chamber, and the gas flow recorder is filled in the form of a rotary flag.

Description

The invention relates to the field of transport and storage of petroleum and petroleum products and can be used, for example, in tank farms. A device for pouring oil products into vehicles is known, consisting of a hinge of the connected parts of the product pipeline, a filling nozzle with a support flange, grips, and a pneumatic sensor of the level limit associated with the shut-off valve lj. However, the pairs formed during the loading process are vented to the atmosphere that leads to pollution of the surrounding medium. The closest to the proposed technical solution is a device for loading petroleum products into transport tanks containing articulated soils. product line piping, gas piping with pneumatic sensor of loading limit, including vertically positioned pipe and gas flow recorder associated with shut-off valve 2J However, when the device is operated at the moment the liquid sensor ends on the pneumatic sensor pipe, the product is discharged into the gas pipe, that when disconnecting the device leads to the spillage of the product and contamination of the environment, and filling the vapor line with the product leads to Occurs in the event of a malfunction of the recorder and the slam-shut valve, which leads to overflow. The aim of the invention is to improve reliability. The goal is achieved by the fact that a device for filling oil products into transport tanks, containing spherically connected parts of a product pipeline, a gas outlet pipe with a pneumatic limit level sensor including a vertically positioned branch pipe and a gas flow recorder connected to a shut-off valve, is equipped with a chamber vertical partition, not reaching to its bottom, into two sections and having a shunting hole on the side wall, while the nozzle of the level sensor communicates ene with a venting pipe through the chamber, and the gas flow register vsholnen a Nogo twist pitch. Figure 1 shows the proposed device, a General view; in Fig.2, view A in Fig.1; figure 3 - node T in figure 1. The device consists of pivotally connected links 1 of the product pipeline with a shut-off valve 2 of the vapor pipe 3, connected to it through the chamber 4, separated by a vertical partition 5, no income 01 to its bottom, and having a shunt hole 6 in the side wall. The device also contains a pneumatic sensor 7 limit level, a gas flow recorder, made in the form of a rotary flag 8 mounted on an axis 9, a carrier magnet 10, interacting with a magnetically controlled sealed contact 11, the germa iziruyuschuyu krshku 12, filler tube 13, the counterbalance spring 14 and grips 15. The apparatus operates as follows. The filling nozzle 13 is lowered into the transport container. The cover 12 is lowered onto the neck 16 and, by means of the grippers 15, the transport container is sealed. At the start command, the shut-off valve 2 opens, the transfer pump and the time relay (not shown) are turned on. The relay time is limited by the specified time required to create a steady flow of vapor-air mixture in the vapor pipe 3. After turning on the transfer pump and the time relay, the main vapor-air mixture, displaced by pouring oil product, enters the chamber 4 through the nozzle of the pneumatic sensor 7 into chamber 4, which through the slot 17, located between the partition 5 and the bottom of the chamber 4 enters the pipeline 3. Simultaneously with the main flow, the steam-air mixture from the tank and through the shunt hole 6 also enters the pipe 3, which eliminates the creation of overpressure under the lid 12. The nominal diameter of the nozzle of the sensor 7 is much larger than the diameter of the shunt hole 6. If the depressurization of the transport capacity did not occur, the rotary flag 8 turns along the flow, including contact 11 which blocks the closed contacts of the time relay. After a specified time

the relay is turned off, and the pouring process controls the contact t1. When the level of the poured oil product reaches the end of the nozzle of the sensor 7, the main flow of the vapor-air mixture stops. The release of a certain volume of product into the chamber 4, due to the impossible instantaneous release of overpressure from under the cover 12 through the shunt hole 6 of the extinguisher (its dynamics) in the area of chamber 4, bounded by a partition 5, does not propagate into the pipeline 3, since the pressure B is the hole 17 is balanced by the back pressure through the schun-isduct and its discharge into the vapor-air

After relieving the overpressure, the transport tank depressurizes, the grippers 15 unlock, and the balancing spring 14 removes the filling nozzle 13 from the transport tank. The device is ready for the next filling.

The use of the proposed device will allow to eliminate the excess pressure in the transport tank after the end of loading, overflow of oil
