Abstract
The utility model discloses an oil unloading and metering device. An outlet of a gettering filter (1) is connected with an inlet of a flowmeter (2). The oil unloading and metering device is characterized in that an outlet of the flowmeter (2) is connected with an air supply mechanism; the air supply mechanism consists of a cylinder (3), a floating ball valve(4) and an upper cover(5); an opening on the upper end of the cylinder (3) is sealed by the upper cover(5); the floating ball valve(4) is arranged on the upper cover(5); an oil inlet (3a) is arranged close to the bottom of the cylinder (3); the middle of the cylinder (3) is provided with an oil outlet (3b); and the oil inlet (3a) is connected with the outlet of the flowmeter (2). When the oil unloading metering device is used for oil unloading of a tanker, air can not pass the flowmeter, so that the flowmeter is always immersed in the oil, thereby ensuring that the media of metering of the flowmeter are all oil and greatly improving the metering accuracy of the device.
Description
Technical field
The utility model belongs to a kind of liquid metering device, specifically, is the demanding tank car Unloading Metering of a kind of measuring accuracy device.
Background technology
The tank car emptying requires to unload clean, but emptying begins and all have air to enter measuring apparatus at last, and air has passed through measuring apparatus and will cause the number of demonstration more than the number of actual oily process, very inaccurate.At present, most of Unloading Metering devices all have air separator in the flowmeter import, and it can eliminate in the pipe and the air before the flowmeter.But when oil product has been put soon, the device import can enter a large amount of air equally, when device outlet position than entering when low, in the device is negative pressure, can suck a large amount of air through the flowmeter metering, cause the accuracy of oil metering low, fail fundamentally to solve air and passed through measuring apparatus and will cause the number of demonstration more, very inaccurate problem than the number of actual oily process.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of air not by quantifier, measures accurate Unloading Metering device.
The technical solution of the utility model is as follows: a kind of Unloading Metering device, the filter outlet of cooling down links to each other with the flowmeter import, its key is: described flowmeter outlet is connected with air supply mechanism, this air supply mechanism is made up of cylinder, ball-cock assembly and loam cake, and cylinder upper end nozzle is sealed by loam cake, in this cylinder ball-cock assembly is housed, this ball-cock assembly valve port seat is installed in and covers, be provided with oil-in near at the bottom of the cylinder tube, the cylinder middle part is provided with oil-out, and described oil-in is connected with the flowmeter outlet.When oil will have been put, liquid level descended in the cylinder, and ball-cock assembly is opened, and the air supply mechanism cylinder communicates with atmosphere.Cool down filtrator and the air supply mechanism air pressure of flowmeter the right and left parallel, and oil has been avoided the air of cooling down in the filtrator in the left side is drawn onto air supply mechanism through flowmeter when the air supply mechanism cylinder flows out, and it is inaccurate to cause flowmeter to measure.
Above-mentioned cylinder inner wall laterally is provided with cowling panel, and this cowling panel is between the oil-out of ball-cock assembly and cylinder.Oil in the air supply mechanism cylinder is carried out rectification, avoid forming wave and cause the ball float of ball-cock assembly to fluctuate up and down.
Above-mentioned cylinder oil-out is equipped with valve, makes things convenient for opening and closing.
Above-mentioned cylinder upper end nozzle is provided with flange and loam cake is bolted to connection.Be convenient to dismounting, keep in repair and clean.
The oil-in of above-mentioned cylinder and oil-out all are welded with flange.
The oil-in flange and the flowmeter discharge flange of above-mentioned cylinder are bolted to connection; The oil-out flange and the valve flanges of described cylinder are bolted to connection.It all is convenient the connection and dismounting.
Beneficial effect: when the utility model is used in the tank car emptying, do not have air through flowmeter, flowmeter is in the oil product submergence all the time, and the medium of dependable flow meter metering all is oil products, has improved the measuring accuracy of device greatly.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the vertical view of Fig. 1.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
As shown in Figure 1 and Figure 2, the utility model Unloading Metering device, filtrator 1 outlet of cooling down links to each other with flowmeter 2 imports, the ball-cock assembly 1a that cools down is equipped with in the filtrator cylinder upper end nozzle sealing of cooling down, cool down filtrator cylinder middle part is provided with import, this import and cool down and be provided with the cowling panel 1b that cools down between the ball-cock assembly 1a is equipped with filter core 1c at the bottom of the filtrator cylinder tube of cooling down; Described flowmeter 2 outlets are connected with air supply mechanism, this air supply mechanism is made up of cylinder 3, ball-cock assembly 4 and loam cake 5, cylinder 3 upper end nozzles are by loam cake 5 sealings, in this cylinder 3 ball-cock assembly 4 is housed, these ball-cock assembly 4 valve port seats are installed on the loam cake 5, after ball float whereabouts ball-cock assembly 4 was opened, cylinder 3 communicated with the external world.Be provided with oil-in 3a near at the bottom of 3 of the cylinders, cylinder 3 middle parts are provided with oil-out 3b, and described oil-in 3a exports with flowmeter 2 and is connected.Cylinder 3 inwalls laterally are provided with cowling panel 6, and this cowling panel 6 is between the oil-out 3b of ball-cock assembly 4 and cylinder 3.Described cylinder 3 oil-out 3b are equipped with valve 7.Described cylinder 3 upper end nozzles are provided with flange and loam cake 5 is bolted to connection.The oil-in 3a and the oil-out 3b of described cylinder 3 are welded with flange.The oil-in 3a flange of described cylinder 3 and flowmeter 2 discharge flanges are bolted to connection; The oil-out 3b flange of described cylinder 3 and valve 7 flanges are bolted to connection.
Principle of work: medium is in the concordant original state that is with the oil-out 3b of cylinder 3 in the measuring apparatus, confirm that flowmeter 2 pointer sum counters return zero, close exit valve 7, slowly open the tank wagon valve and begin to drain the oil, the air in the quick vent pipe of ball-cock assembly 1a of cooling down in the filtrator 1 of cooling down.After a large amount of air had been arranged, pasta continued to rise, and the ball-cock assembly 1a that cools down in the filtrator 1 of cooling down closes.When oil will have been put, liquid level descended in the air supply mechanism cylinder 3, and ball-cock assembly 4 is opened tonifying Qi automatically in the air supply mechanism, kept flowmeter 2 both sides air pressure balances, and air is guaranteed flowmeter 2 meterings accurately without flowmeter 2.
