SU111046A1 - Hydraulic vibrator - Google Patents

Description

The subject of the invention is a hydraulic vibrator driven by a fluid moving in a pipeline.

Known similar vibrators are complex in design and similar to pneumatic-type vibrators — in them the working fluid moves unbalanced masses.

In the vibrator described, this constructive disadvantage is eliminated by the fact that it uses two parallel-connected and oppositely directed tubes and a rotating valve for alternately shutting off the tubes, in order to create alternate and oppositely directed hydraulic shocks in them, which bring the entire system into vibratory motion.

FIG. 1 shows the described vibrator, side view; in fig. 2- rotating valve in the box in the plan (on a larger scale).

A box / with a rotating valve 2 inside and with everything. The pipes are fixed on the plate 5, which must be vibrated.

The rotary valve has a toothed rim 4, to which two pipes are connected, of which through tube 5 to the valve toothed ring W is supplied with a pressure under pressure, which rotates the valve, and waste liquid is withdrawn through the tube 6.

In the middle part of the valve body, at equal distances from the center of its rotation, there are one or several openings 7, and in the case, at the same distance from the center of rotation of the valve, four through holes 5, 8 and 9, 9 are provided :.

When the valve rotates, its openings 7 alternately close either openings 8 and 8, then openings 9 and 9i.

To the openings K and 9i, opposite ends of the tubes 10 and // are attached with their ends. The other ends of these tubes are connected in parallel to the pipeline 5, in which there is a liquidocTb under pressure.

Discharge tubes 12 are connected to openings 8 and 9 and when the valve with openings 7 is rotated, the thrusters 10 and // alternately disconnect from the tubes 12 and, as a result, oppositely directed hydraulic impacts occur in the tubes 10 and //, resulting in all system in a vibratory motion.

Subject invention

A hydraulic vibrator actuated by a fluid moving in a pipeline is only used in that it uses two parallel pipe connections and oppositely directed tubes and a rotating valve for alternately closing the slab in order to alternately create oppositely directed hydraulic shock, drive nuix the whole system into vibratory motion.
