Abstract
A kind of metering verification volume pipe Special vacuum ball picking device of the utility model design, including vavuum pump, sebific duct, handle, vacuum pipeline, main sucker, valve, accessory sucker etc., design a main sucker, 24 accessory suckers, accessory sucker is that universal type is connected with vacuum pipeline, it is ensured that accessory sucker adsorption plane fits like a glove with demarcation ball surface.The utility model, which can be improved, takes ball efficiency；Reduce labor intensity；It is effectively protected demarcation ball surface, it is ensured that the repeatability of volume pipe demarcation.
Description
Technical field
The present invention relates to oil pipeline normal flow calibration technology field, a kind of volume type flow verification dress is related specifically to
Put and middle use spherical displacer taking device.
Background technology
There is a kind of bi-directionally or uni-directionally type volume pipe caliberating device in volume type flow calibration, there is portable two-way at present
Volume pipe flow calibrating device, there is various forms of calibrating calibration equipments such as 45 degree of rotation unidirectional volume pipe devices of folded form.Ball
Volume pipe is a kind of standard, the error for periodic verification volumetric flowmeter and velocity flowmeter, it is ensured that flowmeter meter
The accuracy and reliability of amount, are widely used in the oil product handing-over mouth of petrochemical industry.It is a kind of practicality, reliability, economy, surely
Fixed, the first-class transmission of quantity value benchmark utensil of high-precision national highest ranking precision.Volume pipe by body, verified volume section, put
Parallel operation, detection switch, valve and the sealing composition such as conversion equipment and control system.When volume pipe and flowmeter are connected on process pipelines
On, experimental calirating can be carried out to flowmeter at the scene.Overcome condition of work it is different with test condition caused by error, inspection
During fixed, it be not necessary to open, arrhea gauge, eliminate the error because caused by opening, arrhea gauge, while also eliminates because liquid steams
The error that hair, the difference of condition of work are caused.It has high accuracy, high repdocutbility.According to national metrological verification regulations JJG209-
2010《Volume pipe vertification regulation》Regulation, need to be demarcated for every 3 years to volume pipe.It must be reached inside demarcation front volume pipe clean
It is net to require, i.e., volume pipe is cleaned.Spherical displacer plays displacement, detection trigger switch, sealing and pigging in volume pipe
Main function.Before cleaning volume pipe and when demarcating volume pipe ball picking device need to be used to change spherical displacer every time.The single sucking disc used at present
Formula and gripper formula all have the following disadvantages：Ball picking device is operated using the single sucking disc, and operating condition requires high, and ball surface is demarcated when taking ball
Defect and attachment debris can not occur；Because the adsorption plane of the single sucking disc is small, and the diameter of spherical displacer is generally higher than 300mm, weight
More than 20kg, so the likelihood ratio come off during spherical displacer is taken is larger；And gripper formula is easily because gripper dynamics can not be controlled
System, gripper contact area is smaller, and the probability that causes to come off is also very big.The pawl of other gripper formula is easily destroyed the surface of spherical displacer,
The repeatability of volume pipe can be caused to be unsatisfactory for requiring.The labor intensity and work difficulty that above two ball picking device is brought simultaneously are all big
Big increase.
The content of the invention
The technical problem to be solved
The purpose of the present invention is that there is provided a kind of practical, reliable, stabilization new the problem of presence for above-mentioned prior art
Volume pipe demarcates ball picking device.
The technical scheme is that：One kind metering verification volume pipe Special vacuum ball picking device, the ball picking device is by vavuum pump
（1）, sebific duct（2）, vacuum pipeline（4）, handle（3）, main sucker（5）, accessory sucker（8）, valve（6）Composition, its intermediate pump（2）
With sebific duct（2）One end is connected, sebific duct（2）Other end and vacuum pipeline（4）Connection, main sucker（5）With accessory sucker（8）Install
On vacuum pipeline, valve（6）With handle（3）Also peace turns in vacuum pipeline upper end.Accessory sucker（8）Can be according to spherical displacer（7）'s
Size weight is customized to 2 ~ 4 and claims to be uniformly distributed.
Accessory sucker（8）Connection with vacuum pipeline is universal type connection.Can be according to spherical displacer（7）Size automatically adjust,
Ensure accessory sucker（8）Adsorption plane and spherical displacer（7）Surface fit like a glove.
The present invention is when in use by sebific duct（2）One end and vavuum pump（1）Connection, the other end and vacuum pipeline（4）Connection,
By valve（6）Close, hold handle（3）By main sucker（5）, accessory sucker（8）It is attached to spherical displacer（7）Surface, start vavuum pump
（1）, main sucker（5）And accessory sucker（8）To firmly it adsorb in spherical displacer（7）Surface, then hold handle（3）By spherical displacer
（7）Taken out out of receiving ball tube, by spherical displacer（7）After being put on Place dolly, vavuum pump is closed（1）, open valve（6）, mark
Determine ball（7）Will be with main sucker（5）And accessory sucker（8）Separation, takes ball to complete.
Beneficial effect of the present invention：
1. because increasing the quantity of accessory sucker, operating personnel's quantity is reduced, labour is saved；
2. take the success rate of spherical displacer to reach 100%；
3. the tool operation made is convenient, labor intensity is reduced；
4. other auxiliary equipments need not be added.
Brief description of the drawings
Fig. 1 is schematic structural view of the invention
In figure：Vavuum pump（1）, sebific duct（2）, vacuum pipeline（4）, handle（3）, main sucker（5）, accessory sucker（8）, valve
（6）.
Embodiment
As shown in figure 1, the present invention is when in use by sebific duct（2）One end and vavuum pump（1）Connection, the other end is led with vacuum
Pipe（4）Connection, by valve（6）Close, hold handle（3）By main sucker（5）, accessory sucker（8）It is attached to spherical displacer（7）Surface,
Start vavuum pump（1）, main sucker（5）And accessory sucker（8）To firmly it adsorb in spherical displacer（7）Surface, then hold handle
（3）By spherical displacer（7）Taken out out of receiving ball tube, by spherical displacer（7）After being put on Place dolly, vavuum pump is closed（1）, open
Valve（6）, spherical displacer（7）Will be with main sucker（5）And accessory sucker（8）Separation, takes ball to complete.
