Description

In the proposed device for sampling fluid, a cylindrical vessel with windows in its head parts and valves closing the middle part of it (the vessel) is used. The valves are mounted on the rod and loaded with a spring; The valves are controlled by a cable attached to the stem through a flexible hose or pipe.

The drawing shows a vertical section of the device.

In the cylindrical vessel 1, in the upper and lower heads of it, there are windows 3, .3 for the passage of fluid inside the device with guides 2, 2 for the rod 6, on the threads of which two valves 4, 5 are fastened using nuts with locknuts, which can (sharp: temperature change) to be moved to control their course. The rod b in the top head of the cylinder 1 is surrounded by a spring 7, one end of which rests on the stop 2 of the top head; cylinder 1, and the other on the locknut of the top valve 4; The spring 7 serves to simultaneously close the valves 4, 5 and, depending on the lowering of the device to one or another depth, is changed in order to avoid opening the valves to atmospheric pressure. The rod 6 is attached to a cable 9 passed through the inside of the gas pipe with a threaded end,

screwed onto the device; if used instead of a flexible hose pipe, the latter is supplied with a nipple for connection with the device.

To take a sample of fluid, the instrument is lowered onto a hose or pipe to the required depth and a cable 9 is connected with the rod 6 upwards; valves 4, 5, lifting together with the stem, will open the fluid inlet through the windows 3, 3 into the middle part of the cylinder 1 between the valves. With the release of the cable 9, due to the action of the spring 7, 6 with valves 4, 5, the last (valves) will close the access of fluid to the middle part of the cylinder. Thus, filling the middle part of the cylinder between the valves is liquid and will breakdown from the required depth.

Subject

A device for sampling liquids at any depth (bathomet), characterized in that it consists of a cylindrical vessel 1 fitted with windows 3 and 3 at the head, valves 4 and 5, mounted on the rod 6 and loaded with a spring 7, are used to close the middle part. , for control of which valves a cable 9 was applied, attached to the rod b and passing through a hose or pipe 8.
