Abstract
The utility model discloses a bidirectional ball type volume pipe receiving and delivering ball device comprising a ball barrel, wherein the bottom end of the ball barrel is connected with a concentric reducing joint, a verification ball is placed in the ball barrel and the concentric reducing joint, a quickly opened blind plate is installed on the ball barrel and the side wall of the concentric reducing joint, and a ball supporting device is installed on the side wall at the bottom end of the concentric reducing joint. After an inlet and outlet valve of a volume pipe is closed, the verification ball drops on the ball supporting device, no sealing ring is formed between the verification ball and the concentric reducing joint so that liquid in the volume pipe can be completely evacuated, and the verification ball can be easily drawn out of the ball supporting device through the quickly opened blind plate without using a ball taker with more easy-wearing parts; and therefore, the bidirectional ball type volume pipe receiving and delivering ball device not only is beneficial to protecting the verification ball to avoid earlier damaging the verification and ensure the metering performance of the volume pipe, but also greatly reduces the labor intensity and the ball taking height and saves the construction investment.
Description
Technical field
The utility model relates to and belongs to the flow metering field, refers more particularly to a kind of two-way ball co-volume pipe.
Background technology
Two-way ball co-volume pipe is a kind of flow standard device, is used for liquid flowmeter is examined and determine, and guarantees accurately metering and fair handing-over, is widely used in the flow metering field of industries such as oil, chemical industry.The two-way ball co-volume pipe of present home and abroad prior art, as shown in Figure 1, mainly comprise calibrating ball 1, sloper 2 with one heart, ball tube 3, fast opening blind 4, reversal valve 5, secondary ball tube 6, first detector switch 7 and standard pipe 8, pretravel pipe 9 and formations such as exhaust-valve 10, second detector switch 11.Wherein sloper 2 with one heart, ball tube 3 and fast opening blind 4 constitute two-way volume pipe transmitting-receiving ball device.Among Fig. 2, fast opening blind 4 is opened, and utilizing ball picking device 16 will examine and determine ball 1 taking-up from two-way volume pipe transmitting-receiving ball device is the present general ball mode of getting of domestic and international two-way volume pipe.Getting the ball process is: when calibrating finishes to prepare to get ball, calibrating ball 1 enters ball tube 3 from pretravel pipe 9, the volume pipe terminal valve is closed, after opening 10 pairs of volume pipe of exhaust-valve and carrying out emptying, open fast opening blind 4, the leather cup of ball picking device 16 is held in calibrating ball 1 surface, and operation vacuum withdraw device 17 produces enough vacuum between the leather cup of ball picking device and calibrating ball, will examine and determine ball 1 with external force and pull out from ball tube 3.
Position I is the position of preparing ball picking device 16 when ball tube 3 is got ball among Fig. 2.The position II is the position with ball ball picking device 16 when ball tube 3 takes out.
Existing transmitting-receiving ball device weak point is:
1, because sloper 2 osculum sizes is littler than calibrating ball 1 diameter with one heart, after the volume pipe terminal valve is closed, calibrating ball 1 drops under the effect of gravity in the concentric sloper 2, form sealing ring, ball tube 3 and pretravel pipe 9 are separated, after carrying out emptying by 10 pairs of volume pipe of exhaust-valve, cause in the 1. ball tube 3 reversal valves 5 not gone out with following row of ball tube associated line with the liquid of calibrating ball 1 or more, increased and got ball exercise and make difficulty; 2. the calibrating ball portion is pressed in the pretravel pipe 9 that is connected with concentric sloper 2 under the oily heavy synergy that the row who conducts oneself with dignity and mentioned does not just now go out, this just need allow and reach higher vacuum tightness between ball picking device leather cup and the calibrating ball, the calibrating ball could be taken out from volume pipe.Excessive vacuum tightness requires not only can make the calibrating ball very big distortion to occur, quickens the calibrating ball and damages, and has influence on the metering performance of volume pipe, also can make the 17 easier damages of ball picking device vacuum withdraw device, increases the operation labour intensity of manual vacuum draw-out device.
2, the ball tube needs ball picking device length to add calibrating bulb diameter sum to get the spherical space height more than 1.1 times at least more than 3.When the calibrating bulb diameter is big, also need install special lifting facility additional, need the bigger spherical space height of getting.Because it is indoor that volume pipe generally is installed in, the increase of getting the spherical space height can a lot of construction costs of corresponding increase.
The utility model content
Technical problem to be solved in the utility model provides a kind ofly can either protect the calibrating ball, does not need ball picking device can conveniently take out the two-way ball co-volume pipe transmitting-receiving ball device of calibrating ball again.
For solving the problems of the technologies described above, the technical solution of the utility model is: two-way ball co-volume pipe transmitting-receiving ball device, comprise the ball tube, described ball tube bottom is connected with concentric sloper, be placed with the calibrating ball in described ball tube and the concentric sloper, on described ball tube and the described concentric sloper sidewall fast opening blind is installed, on the bottom sidewall of described concentric sloper the holder ball device is installed.
As optimized technical scheme, described holder ball device comprises oil cylinder and is installed on in-oil cylinder flexible push rod that described flexible push rod is concordant with the fast opening blind bottom.
Owing to adopted technique scheme, two-way ball co-volume pipe transmitting-receiving ball device, comprise the ball tube, described ball tube bottom is connected with concentric sloper, be placed with the calibrating ball in described ball tube and the concentric sloper, on described ball tube and the described concentric sloper sidewall fast opening blind is installed, on the bottom sidewall of described concentric sloper the holder ball device is installed; After the volume pipe terminal valve closed, the calibrating ball drops on the holder ball device, no longer form sealing ring between calibrating ball and the concentric sloper, liquid in the volume pipe can be emptied completely, do not need like a cork the calibrating ball to be transferred to by fast opening blind from the holder ball device with the more ball picking device of consumable accessory again, not only help protection calibrating ball, avoided calibrating ball premature damage, guaranteed the metering performance of volume pipe; Significantly reduced labour intensity again, also reduced and got the ball height, saved to build and dropped into.
