Abstract

Использование: повышение расхода и количества жидкостей. Сущность изобретени трубо- поршнева установка содержит калиброванный участок трубопровода с сигнализаторами положени расположенного в нем шарового поршн тройник , привод с валом, расширитель с лкжом, узел перевода поршн выполненный в виде коэксиально расположенных внутреннего и наружного цилиндров . Во внутреннем цилиндре расположен клапан жестко св занный с тройником и расширителем, диаметр люка не меньше диаметра внутреннего цилиндра 1 ил.Usage: increase the flow rate and quantity of liquids. SUMMARY OF THE INVENTION A tubing-piston installation comprises a calibrated section of a pipeline with position indicators of a spherical piston tee located in it, a drive with a shaft, an expander with a housing, a piston translation unit made in the form of coexially arranged inner and outer cylinders. In the inner cylinder there is a valve rigidly connected to the tee and expander, the diameter of the hatch is not less than the diameter of the inner cylinder 1 sludge.

Description

Изобретение относитс к измерител м расхода и количества жидкостей и предназначено дл градуировки и поверки расходомеров и счетчиков жидкостей в различных отрасл х промышленности.FIELD OF THE INVENTION The invention relates to flow meters and liquid volume meters, and is intended for calibration and calibration of flow meters and liquid meters in various industries.

Известна трубопоршнева установка (ГПУ), состо ща из калиброванного участка трубопровода с двум сигнализаторами прохождени шарового поршн через начало и конец участка, вход которого сообщен с тройником, а тройник сообщен с узлом перевода поршн .A known tube-piston unit (GPU) is comprised of a calibrated section of a pipeline with two signaling devices for the passage of a ball piston through the beginning and end of a section whose input is connected to a tee and the tee is connected to a piston translation unit.

Недостатком такой трубопоршневой установки (ГПУ) вл етс больша трудоемкость ремонта в св зи с трудност ми доступа к внутренним детал м узла перевода поршн .A disadvantage of such a tube-piston unit (GPU) is the high complexity of the repair due to difficulties in accessing the internal parts of the piston transfer assembly.

Целью изобретени вл етс уменьшение трудоемкости ремонта путем извлечени внутренних узлов.An object of the invention is to reduce the complexity of repair by removing internal components.

Цель достигаетс тем, что в ТПУ, содержащей калиброванный участок трубопровода с сигнализаторами прохождени шарового поршн , концы которого фланцами соединены: верхний - с расширителем, нижний - с тройником, причем тройник и расширитель соединены узлом перевода поршн , корпус которого выполнен в виде наружного и внутреннего цилиндров, при этом наружный цилиндр стационарно соединен с тройником и расширителем, а во внутреннем цилиндре, расположенном ко- аксиально наружному, размещен клапан, с которым входит в зацепление вал привода, проход щий через радиальные отверсти наружного и внутреннего цилиндров, а со- осно с внутренним цилиндром в расширителе выполнен люк, диаметр которого не меньше диаметра внутреннего цилиндра.The goal is achieved in that in a TPU containing a calibrated section of the pipeline with signaling devices for passing a ball piston, the ends of which are connected by flanges: the upper one with an expander, the lower one with a tee, and the tee and expander are connected by a piston translation unit, the body of which is made in the form of external and internal cylinders, while the outer cylinder is stationary connected to the tee and expander, and in the inner cylinder, located coaxially to the outer, there is a valve with which the drive shaft engages, od radial holes extending through the outer and inner cylinders and co-Ba with the inner cylinder is formed in the expander hatch diameter no smaller than the diameter of the inner cylinder.

На чертеже показана принципиальна схема предлагаемой ТПУ.The drawing shows a schematic diagram of the proposed TPU.

ТПУ состоит из калиброванного участка 1 трубопровода, верхний и нижний концы которого снабжены сигнализаторами 2 и 3,TPU consists of a calibrated section 1 of the pipeline, the upper and lower ends of which are equipped with signaling devices 2 and 3,

Claims

The claims

PIPE INSTALLATION, comprising a calibrated section of the pipeline with position indicators of the ball piston located in it, a tee and a piston translation unit, characterized in that it is equipped with an expander with a manhole in it and a drive with a shaft, a piston translation unit

ball piston 4, expander 5 with hatch 6 and grill 7, tee 8, piston translation unit 9, consisting of an outer cylinder 10, in which is coaxially located

inner cylinder 11. In cylinder 11, a ball valve 12 is arranged having a cup 13, a square hole 14 for engaging with the square end of the shaft 15 of the drive 16. The shaft 15 passes through the radial holes 17 and 18 of the cylinders 10 and 11. The valve 12 is sealed by a sleeve 19.

TPU works as follows. Verification fluid circulates through the calibrated section 1 of the pipeline. 180 ° rotation of valve 12 with actuator

16 ball piston 4 is fed into the tee

8 and, carried away by the fluid flow, passes

. calibrated section 1, including

signaling devices 2 and 3. At the end of its run, falling into the expander 5 and hitting the grate 7, it enters the valve 12. Turning the valve 12 to its original position, the piston 4 enters the glass 13.

TPU ready for re-cycle.

When repairing the internal parts of the piston translation unit, for example, replacing the cuff 19, adjusting the pressure of the cuff 19 against the valve 12, after stopping the circulation of the test fluid, the hatch 6 is opened, the shaft 15 of the actuator 16 is pulled out of the channel 18, the inner cylinder 11 is pulled out, repairs are being carried out are inserted, the inner cylinder 11 is returned. The shaft 15 of the actuator 16 with the valve 12 is engaged, and the hatch 6 is closed.

Opening one hatch, extending the drive shaft and removing the inner cylinder with a valve and sleeve requiring frequent maintenance reduces the complexity of the repair work.
