Abstract
The utility model provides a novel closed oil loading system of a tank car, which consists of a loading arm, a recycling pipeline and a manhole closed compaction device combined with the recycling pipeline, and is characterized in that the manhole closed compaction device is connected with a hydraulic system. The adopted system not only can be applied to tank cars of various specifications and but also guarantee the closed effect, thus the oil gas that volatiles through the manhole when oil is loaded can be smoothly collected in an oil gas storage tank.
Description
Technical field
The utility model relates to the light oil Canning Technique that is used for rail tank car, the airtight charge of oil of particularly a kind of tank car system.
Background technology
The light oil can of rail tank car, the manhole that normally utilizes loading arm to inject the tank car top carries out.In the charge of oil process, tank car in-to-in air pressure has the process of a dynamic change.During by the charge of oil hole charge of oil on the manhole cover, should consider the input of oil, consider that again oil gas reclaims and oil-air pressure safety.Can collect gas recovery system for oil smoothly by the oil gas of manhole volatilization when the gordian technique that railway trestle work oil gas reclaims is charge of oil reclaims.Common solution is to connect one section recovery channel at charge of oil hole back seal, makes oil gas to be input to by the external pipeline of this recovery channel in the oil gas holding vessel.
Because the difference of tank car specification, the charge of oil hole size is also inequality, and this is difficult to be protected with regard to the sealing effectiveness that makes joining place between recovery channel and the charge of oil hole.Therefore, be necessary the airtight charge of oil of the tank car that comprises loading arm and recovery channel system is improved innovation.
The utility model content
The utility model is at defective that exists in the prior art or deficiency, the airtight charge of oil of a kind of later-model tank car system is provided, adopt this system, can either be suitable for the tank car of different size, can ensure obturation effect again, can collect smoothly in the oil gas holding vessel by the oil gas of manhole volatilization when making charge of oil.
The technical solution of the utility model is as follows:
The airtight charge of oil of tank car system comprises loading arm, recovery channel, and the airtight pinch device of the manhole that is connected with recovery channel is characterized in that: the airtight pinch device of described manhole connects hydraulic efficiency pressure system.
Described recovery channel connects the oil gas holding vessel by external pipeline.
Described recovery channel is a kind of flexible pipeline.
The oil spilling warning device is installed on the described loading arm.
On the described loading arm pressure sensor is installed.
Technique effect of the present utility model is as follows:
Because the airtight charge of oil of the utility model tank car system, adopted the airtight pinch device of manhole to connect the structure of hydraulic efficiency pressure system, thereby can make the airtight pinch device of manhole further compress the charge of oil hole, the oil gas of manhole volatilization can be collected in the oil gas holding vessel smoothly by recovery channel when making charge of oil.The introducing of hydraulic efficiency pressure system makes the utility model become a kind of compression type hydraulic pressure closed system of going up, and relies on hydraulic efficiency pressure system that the sealing effectiveness of joining place between recovery channel and the charge of oil hole is fully ensured, and can be suitable for the tank car of different size.
Recovery channel adopts the telescopic pipe duct device, and along with increasing of vaporizing oil-gas, the concentration of gas, pressure increase in the tank car, and flexible pipeline is free to convergent-divergent, and when stretching pipe expansion above the charge of oil hole, the pressure that produces also makes the charge of oil hole more airtight downwards.
Oil filling riser is equipped with oil spilling warning device, pressure sensor, and as charge of oil liquid level contact warning device in the tank car, then interlock system starts, and stops electromagnetic valve, prevents oil spilling.Airtight charge of oil system is equipped with pressure-detecting device, monitor oil-air pressure in the tank car in real time, start in real time vacuum pump and extract oil gas, make in the tank car oil-air pressure be in that (relevant regulations of country: the oil-air pressure that airtight place produces is not more than 4500～6000Pa) in the safe range.
Description of drawings
Fig. 1 is the airtight charge of oil system architecture of a utility model tank car scheme drawing.
Reference numeral lists as follows:
The 1-loading arm, 2-hydraulic efficiency pressure system, 3-pressure sensor, 4-oil spilling warning device, the 5-pipeline that stretches, the airtight pinch device of 6-manhole, 7-oil gas holding vessel, 8-tank car.
The specific embodiment
At first, be described as follows with regard to technology path of the present utility model:
Can collect gas recovery system for oil smoothly by the oil gas of manhole volatilization when the gordian technique that railway trestle work oil gas reclaims is charge of oil reclaims.Consider that when the airtight charge of oil of design system the difference of tank car specification, charge of oil hole size are also inequality, in the design of the airtight charge of oil of tank car system, at first loading arm is transformed, compression type hydraulic pressure closed system in the employing relies on hydraulic efficiency gear (hydraulic efficiency pressure system) to make recovery channel compress the charge of oil hole; Secondly the recovery channel leading portion is adopted the telescopic pipe duct device, along with increasing of vaporizing oil-gas, the concentration of gas, pressure increase in the tank car, and flexible pipeline is free to convergent-divergent, when stretching pipe expansion above the charge of oil hole, the pressure that produces also makes the charge of oil hole more airtight downwards.
Extract tank car bottom oil remaining during the tank car charge of oil earlier and preset oil capacity according to the model of tank car, measure by flow counter by automatic charge of oil system opens solenoid valve, oil filling riser top is equipped with oil spilling warning device, pressure sensor, as charge of oil liquid level contact warning device in the tank car, then interlock system starts, stop electromagnetic valve, prevent oil spilling.Airtight charge of oil system is equipped with pressure-detecting device, monitor oil-air pressure in the tank car in real time, start in real time vacuum pump and extract oil gas, make in the tank car oil-air pressure be in that (relevant regulations of country: the oil-air pressure that airtight place produces is not more than 4500～6000Pa) in the safe range.
The utility model is described in further detail below in conjunction with accompanying drawing (Fig. 1).
Fig. 1 is the airtight charge of oil system architecture of a utility model tank car scheme drawing.As shown in Figure 1, the airtight charge of oil of the utility model tank car system comprises loading arm 1, recovery channel (selecting flexible pipeline 5 among the figure for use), and the airtight pinch device 6 of the manhole that is connected with recovery channel, the airtight pinch device 6 of manhole connects hydraulic efficiency pressure system 2.Recovery channel connects oil gas holding vessel 7 by external pipeline.Oil spilling warning device 4 and pressure sensor 3 are installed on the loading arm 1.Also shown among Fig. 1 the airtight charge of oil of tank car system in when work the situation that is connected with tank car 8.
Should be pointed out that the above specific embodiment can make those skilled in the art more fully understand the invention, but do not limit the present invention in any way creation.Therefore, although this specification sheets has been described in detail the invention with reference to drawings and Examples,, it will be appreciated by those skilled in the art that still and can make amendment or be equal to replacement the invention; And all do not break away from the technical scheme and the improvement thereof of spirit and scope of the present utility model, and it all is encompassed in the middle of the protection domain of the invention patent.
