Definitions

  • the invention relates to a 3-way ⁇ -Ven i1 with a valve body for controlling a flow and a counterflow.
  • a 3-way Ven i1 can e.g. B. can be used to control a flow in the sense that it is either passed or shut off, with a counterflow being passed through the valve body in the event of the flow being shut off.
  • a counterflow can serve, for example, to clean a supply line to the valve body.
  • ß-3-Vgenti1 is characterized in that a cylindrical bore is provided for the flow in the valve body, into which a breakthrough opens radially, the bore and breakthrough leading the flow, and coaxially into the bore a closed tube with a connection for protrudes the countercurrent, the wall for the
  • Passage of the counterflow has at least one opening and on which an elastic sleeve sealing the opening is fitted, with an annular gap between the sleeve and the wall of the bore through which the flow is directed, and when the counterflow is introduced, the sleeve for sealing the Breakthrough is widened and thereby the countercurrent flows from the opening into the hole.
  • the wall of the tube is expediently designed such that two opposing openings are provided in it and an annular groove is made in the region of the openings in the tube wall. If the countercurrent is then introduced into the tube, there is a radial pressure surge extending around the tube in the area of the two openings and the annular groove extending through the openings, which expands the sleeve evenly and applies it to the wall of the bore. Because of the uniform widening of the sleeve, it rests completely like a ring on the wall of the bore, so that it does not matter at which point the opening opens into the bore. The breakthrough is thus sealed with certainty by the widened sleeve, so that the countercurrent is directed from the opening into the bore, from which the countercurrent then passes into a connected feed line and in this develops the desired effect.
  • FIG. 1 shows a sectional drawing of the 3-way valve with the flow passing through
  • Figure 2 shows the same 3-way ⁇ valve with the sleeve expanded by the counterflow and supplying the counterflow to the bore.
  • the 3-way valve shown in Figure 1 consists of the valve body 1, in which the cylindrical bore 2 is embedded.
  • the bore 2 ends in the shoulder 3, which is pierced by the tube 4 inserted coaxially in the valve body.
  • the tube 4 is closed within the bore 2 by the bottom 5. It has the two opposite openings 6 and 1, which are created by a through-hole radially penetrating the tube 4.
  • the annular groove 8 is embedded in the wall of the tube 4.
  • the sleeve 9 made of elastic material is fitted, which spans the pipe 4 and thus seals the two openings 6 and 1.
  • the sleeve resting against the tube 4 leaves the annular gap 13 open with respect to the wall of the bore 2.
  • the opening 10 is finally let into the valve body 1.
  • the opening 10 has an internal thread 11 to the outside, into which any supply line can be screwed.
  • the internal thread 12 is cut into the valve body 1 in the region of the bore 2, which also serves for screwing on any supply line.
  • the tube 4 protrudes from the valve body 1, so that z. B. a hose can be pushed on.
  • FIG. 2 shows how a countercurrent fed to the pipe 4 works.
  • the countercurrent flows according to arrow G1 into the tube 4 and thus through the two openings 6 and 7 into the annular groove ⁇ .
  • the sleeve 9 Due to the pressure of the counterflow G1, the sleeve 9 is expanded, whereby it lies against the wall of the cylindrical bore 2 over its entire circumference and thus seals the opening 10 from the inside.
  • the sleeve 9 releases the annular groove 8 in the direction of the bore 2, so that the countercurrent G1 can emerge from the lifted sleeve 9 and enter the bore 2.
  • the counterflow then emerges from the bore 2 as stream G2. He can then have a desired effect, z. B. unfold a cleaning effect.
