SU20016A1 - A crane that automatically passes a certain amount of fluid - Google Patents

Description

The proposed valve is intended to automatically supply liquids in predetermined quantities.

In FIG. 1. shows a section of a crane with a lowered spool; Phy 2 is the same, with the spool raised.

The valve is made in the form of a double spool consisting of the lower part of a smaller diameter 4, which serves to close the passage of fluid from the pipe 1a to the pipe 1c, and the upper part of the larger diameter consisting of a cup 7 with pr; by cutting 17 in the wall, into which, after, the lifting of the spool in its upper psaton, a liquid flows through the pipe 14 connected to the highway la; Forcing his opus 4ates opus all spool down. The lower part of the spool 4 has an internal cavity 5 which connects to the pipe 1 in the center and the hole b, which is closed when the valve is raised by the rod, 9,; under the action of the springs. 10 10. The longitudinal channel 8 in the rod 9 serves

for the passage of air into the chamber; D. five

When you press the lever 18 ka; the rod 2, which rests with its .thy | eoc6y plane 13 into the spool 4, the latter rises upwards, and the liquid from the pipes1a arrives at a certain speed into the lett pipe and then any other

direction. Spring 3, releasing from the bust, releases the rod 2 and the starting position. The spool 4, being under the pressure of the fluid passing through the tubes 1a, and 1c, cannot fall and stop the flow of fluid from the tubes: s 1a into the tube 1c. At the same time, the upper position of the spool 4 is due to: p having a wall 19, a recess 17 opens a hole 16, in which, thanks to 14, the fluid press in the pipe 1a and the retaining flap 20, the liquid enters chamber A. The intake of fluid is controlled by a screw; 15. on the other hand; when the spool 4 moves upward, the internal cavity of its 5 encounters a sterile, 9 g (, which enters this cavity; it closes the fluid in the opening 6.) At the top of the rod 9 there is a leather sleeve 22 to prevent liquid from entering chamber B. This way you reach the complete impenetrability of the walls, chamber A, and only through the opening 16 the fluid continues to flow into the space above the thicket 1 of the spool 4 ,,;

When filling the chamber A, the amount of liquid determined, in accordance with the installation of the reg of the street screw 15, gold sol. 4. iodine. influenced by neer

the weight of this fluid will overcome the resistance of the fluid moving through the pipes 1a and 1b, will lower into its initial position and close hole 19 with wall 19, thus stopping the flow of fluid into chamber A. Simultaneously, rod 9 will come out of cavity 5 and inform using a b hole with a pipe 1e. Through the channel 8 in the rod 9 and through the hole in the tube 23 air enters the chamber A.

The subject of the patent.

A valve that automatically transmits a certain amount of fluid, characterized by the fact that its valve 4 is provided at the top with a cup 7 with a slot 17 in the wall that communicates when the valve is raised above spool cavity A with a branch 14 of line 1a in order to fill the valve in place, for the release of water from it, a hole b in the lower part of the spool is intended, which connects the main line le with its internal cavity 5, for locking the opening as the spool is used The action of the spring 10 rod 9 with a longitudinal channel 8 for the passage into the cavity And the air of its emptying.
