Description

The invention relates to devices for sampling liquids and consisting of a cylinder with a spring cap and a piston. In the proposed device for opening the cover, a rod fastened to the piston is applied.

In FIG. 1 shows a vertical section of the device; FIG. 2-part of a rod passed through a tube with a spring mounted on it; FIG. 3-horizontal section of the cylinder; FIG. 4- view of the cover from below; FIG. 5 is a perspective view of the spring holding the cover down; FIG. 6-way to connect parts of the device.

The device consists of a metal cylinder 1 (Fig. 1) with its rod 2 passing through the center, the lower end of which enters the narrow opening 3, 4 attached to the cylinder walls, but does not reach the opening cover 5. The rod is provided with an upper end of heading 6 (fig. 2); Below the heading b, a steel spring 7 is put on the rod and even lower than the last - handle 8, tightly attached to the tube 9 extending from the handle 8 to the cylinder 1, to which it is soldered in the neck 10. To the rod 2 passing through the whole

tube 9, attached piston 11 (from thick, well fitting), which is pressed on both sides by round metal plates 12, 13. Cover 14 below the projecting, notched face 15

Cylinder 1 has a 4 mm wide screw thread (shown in dotted lines in the drawing) by which the cover 14 is unscrewed from the device by unscrewing, and thus, after use, it is possible to easily disassemble the device and clean it inside. The loop 17.18 (figs. 1 and 4) is soldered on one side to the wall of the device 1, and the other side - to the rysh 5, 16. A steel spring 19, 20, 21 is attached to the loop 17.18 (fng. 5), constant Pressing the cover 5, 16 from the outside.

The fluid sample is obtained as follows: the instrument is immersed to the desired depth in the fluid; pressure

fingers on head 6, last lowered

close up; the rod 2 descends, pulls the piston 11 and simultaneously pushes the lid 5. After removing a finger from the head 6, the rod rises by the piston 11, the liquid is sucked in, and when the rod 2 enters the device, the lid & 5 tightly covers the hole.

For convenience, the rod 2 to the tube 9 can be folded from several parts by means of screw cuts 22 both on the rod and on the tube (Fig. 6). This makes it possible to increase or reduce the length of the device, in accordance with the size of the liquid storage.

The subject matter of the invention.
