SU24672A1 - Cylinder test press - Google Patents

Description

The proposed press is designated for pressure testing of several cylinders at once, having two opposite rows in its frame | made in the form of a wide and flat trough, and fixed with screw clips to inclined walls or the bottom of this trough. The press is offered in two forms: in the main type of press, the test is carried out with water, filling pressurized cylinders that are positioned obliquely with the neck down, and in a modified one - with compressed air, and the trough of the bed is filled with water, and the cylinders are also inclined but with the mouths upwards.

In FIG. 1 shows a cross section of a press ;, FIG. 2; - longitudinal section of the initial part of it; FIG. 3 and 4 - two projections of its details (tee); FIG. 5 - 8 - four cuts of another part (distribution head); FIG. 9- cross section of a modified press; FIG. 10 is a side view with a partial section of its parts (rack with bracket).

The riveted bed of the press is shallow — 7, a width not less than / double the length of the cylinders and a length — depending on the number of cylinders tested simultaneously (Figs. 1, 2 and 9), lying in the middle of its bottom on the main longitudinal riveted beam 2, and the inclined walls of the sides or bottom - on the transverse ribs coming from it 3. In the main type of press

(Fig. 1, 2) several tees 5, (according to the number of pairs of test cylinders) of a special form (Fig. 3 and 4) are placed on the centerline of the bottom of the trough, into which water from two highways 16 located on the sides of the trough are fed by pipes 17. Distributive heads b (Fig. 5, b, 7, and 8) are attached to the side triangular flanges of each tee, each of them is provided with channels and two valves inside: a spring 7 and a self-acting 8. On the opposite side of the tee, each head has 9 tubes from it ( Fig. 6), inserted with another open end into the test cylinders 4, adjacent to the installation with the installation of a rubber ring with their mouths to the undercut on the cook v of the head b around the tube 9. Cylinders are placed on both sides of the trough on the abdominal 10 (Fig. 1) attached nnye to the inclined walls of the trough, and are pressed by their necks to the heads used with screw clamps // connected by connecting rods 12 with the lateral pins 13 (FIG. 4) on the tees 5.

The press job is as follows. Having filled the press with cylinders, they include bulk water, which from pipes 16 goes through pipes 17 to tees 5, from there to distribution boxes b and through internal channels and annular gaps (6) in the heads between the neck of the cylinder and tube 9 will flow into the cylinders than the air displaced from them by the water will go through these tubes and through the air KanaAaiii 6 through the Kapan 7 open at that time to the atmosphere. When the water in the cylinders reaches the level of the open ends of Urubok 9, it will be ejected through the same way as the previously displaced air through the valve 7 to the outside in the form of a stream and will let you know about filling the cylinders with bulk water. Then by means of a handle 14 (Fig. 1 and 2) sitting on a common shaft 25 and double-arm levers / 5 (Figs, 1 and 6) with each head enable the valves 7 of all heads 6 to close under the action of springs, and turn on the plumbing net / b, 77 accumulator water under pressure up to 60 atmospheres with which the cylinders are tested for a set time. Thereafter, the storage water is shut off, the network is connected to the sewage system, and the pressure in the cylinders is brought to atmospheric pressure. In order to remove water from the cylinders, from the air lines 18 (Fig. 1 and 2), laid under the side walls of the trough, through the pipes 19 in the head 6 (Fig. 1 and 7) air is blown under pressure 4-10 atmospheres lifting valves 8 in the heads, passes through the pipes 9 into the cylinders and displaces water from them through the channels in the heads 6 back into the water supply network, now connected to the sewage system. After loosening the screw clips, the cylinders are removed, and the entire presser mechanism lies on the sides of the trough.

With the modification of the press (Fig. 9) the cylinders 4, which are laid obliquely into the reservoir / (trough) filled with water through the pipe 20, with their cylinders on the abdominal 21 with the clamps and the necks on the uprights 22 (Fig. 9 and 10) are tested by the air flowed under pressure up to 50 atmospheres from lines 23 through pipes 24 to racks, 22. The openings of the tested cylinders are placed by the outer openings of their open valves on

Parts of the ст racks and tightly pressed to them with screw clips 26 (Fig. 9 and 10) and the air under pressure, through the channels in the racks 22 fills the cylinders. The infiltration of air through the defective openings of the cylinders is determined by the bubbles passing through the water, and, for better observation, the bottom of the tank 1 is provided with windows that let the light from the lamps 27 into the water.

The subject matter of the invention.

Claims (2)

1. A press for testing cylinders arranged in two opposing rows on a bed in the form of a trough, to inclined walls and the stops of which the cylinders are fastened with a clip that presses the pressure screw, which press is equipped with pipelines for filling the system with water or air, which is different when using reinforced from the line of tees 5 (figs. 1-4) distribution heads 6 (figs. 5-8) equipped with self-acting valves 8 for supplying air displacing water from the cylinder, and spring valves 7 under the action of p chagov / 5 (FIGS. 1 and 6) for discharging air displaced emogo water supplied for testing, what is communicated to the head distribution tubes 9 (Fig. 6) with a cavity cylinders. 2. Press change according to claim 1, characterized by the use, instead of tees 5 (Fig. 3, 4) and distribution heads b (Figs 5-8), racks 22 (Figs 9 and 10), equipped with channels, in order supply air under pressure to cylinders, press mfM to racks using removable brackets (Fig. 9, 10), carrying pressure screws, which cylinders are immersed in a water-filled reservoir / equipped with portholes in its bottom to transmit light from the lamp 27 to the reservoir water in order to observe in the process of testing.
