SU808899A1 - Liquid sampler - Google Patents

Description

one

The invention relates to chemical and petroleum engineering and can be used in the technique of storing and transporting liquids in pipelines.

Known sampler fluid containing the pump and the perforated intake tube, step and perforation section of perforations which is determined by calculation, based on the performance of the pump tl.

A disadvantage of the known device is the design complexity and low accuracy.

Also known is a sampler containing an I-shaped perforated tube and a metering device made in the form of a gash placed in the other end of the tube 12J.

A disadvantage of this device is the insufficient accuracy of sampling over the height of the liquid column and the complexity of the device.

The purpose of the invention is to improve the accuracy and simplify the design of the device.

The goal is achieved by the fact that the ball of the metering device is made of a material whose density is less than the density of a liquid,

and placed in a perforated tube, in the lower part of which a saddle is made and a stopcock is installed, and the total area of perforations is less than the section of the tube. This embodiment allows to simplify the device and improve the accuracy of sampling.

The drawing shows the device, a longitudinal section.

The device consists of an ICJ tube with perforations 2, at the lower end of which a stop valve 3 is installed, and inside the tube, the ball moves out of the fixed seat 5. The upper end of the tube has a bend 6 and a plug 7.

The device works as follows.

0

Before taking a sample, a thermostat is installed across the faucet 3 and the liquid is opened. Under its own weight, the liquid flows out of the perforated tube 1 into the thermostat. Together with

The 5th bone lowers the ball 4. After the fluid flows out with a volume slightly larger than the volume of the perforated tube, the ball 4 lowers and closes the saddle 5. The outflow of fluid stops. 0 (Crane 3 can be closed.

Claims (1)

Claim A liquid sampler containing a perforated tube and a metering device made in the form of a ball placed in the tube, characterized in that, in order to improve accuracy and simplify the design, the ball of the metering device is made of a material whose density is less than the density of the liquid, and placed in a perforated tube , in the lower part of which a saddle is made and a stopcock is installed, and the total area of the perforation passage section is less than the pipe passage section.
