Description

DEVICE FOR JACKERS TESTING

It was filed on August 13, 1939 for L 26116 to the People's Commissariat of Medium Machine-Building of the USSR

The main author. St. for .Yg 52179 from 30 March 1937 on the name of S.A. P. Slother

Basically auth. St. JXb 52179 described the device d.; 1 test Yachik.lerov of the projectile fluid, made in the form of a joint, egos with a vessel of the tee, in the tubes of which it was strengthened;

The proposed device is a further development of the device according to the basic author. St. and distinguish the term that the tube, the non-carbon test subject, is equipped with a process open from above and d.1 of the difference of the nanor difference is elongated compared to the tube carrying the reference jet. This achieves such test automation, for which the end time of the tests does not depend on the test driver.

The drawing shows s.hema of the proposed device.

The upper part of the device body is equipped with a tubular tee, the upper opening of which is communicated through the valve / with reservoir 2, and the tip with a constant reference nozzle 4 is attached to the short bend 3. Into the long bend - tube 5 triple: the tip is inserted with a test lead. at the end of the jet 5.

Tube 5 is provided with an open-ended process 7 for air to escape from it when the tube is filled with water and elongated downwards compared to short bend 3. Below tube 5 is a vessel 8 for collecting liquid, and beneath bend 3 a vessel 9 having a scale for reading. In the vessel 8 enters the fluid flowing from the test jet, and in the vessel 9 - the fluid flowing from the reference jet.

The operation of the device is based on the fact that when turning the crane 1 at the same time, the liquid begins to flow from the upper reservoir 2 through the reference and through the tested nozzles, then fall, respectively, into the vessels 5 and S and the FLOOR of them.

The removed end of the tube 5 allows you to create a difference in pressure. The jets and use the effect of this difference to obtain automatic measurement, since, in this case, the measurement will end without the operator at the time when the water is exhausted to the level of the reference hole. jet on the short knee 3.

The dotted line 10 inside the tube 5 shows a thin inner tube to facilitate the escape of air upward from the tube .5 k to prevent it from entraining with the water downwards.

Subject invention

The form of the device for testing jets on the author. St. 52179, characterized in that, in order to achieve test automation,: With which the end time of the latter does not depend on the observer, the tube carrying the test jet is equipped with an open at the top for air outlet and for creating a pressure difference is elongated compared to the tube carrying reference jet.
