Definitions

  • the invention relates to a valve or throttle device for a fluid Flow, in particular a flow carrying solids, in particular a stock suspension or white water of a paper machine, according to Preamble of claim 1.
  • a similar valve or throttle device is from the Patent application DE 44 02 516 A1 known to the applicant.
  • valve in the known design has the disadvantage that cleaning with only one complex disassembly of the valve is possible.
  • the object of the invention is achieved by the features of claim 1 solved. Accordingly, it is proposed the hollow body of the valve to share so that all through an opening in the cavity essential inner surfaces of the Cavity of a problem-free cleaning are available.
  • An advantageous embodiment of the device according to the invention can be achieved in such a way that the inlet opening of the hollow body is designed that the flow flowing through the hollow body is loaded with a rotational component.
  • This Rotational component leads to an undesirable deposit in the Hollow body of solid particles is difficult.
  • the device consists in such a way that the flow guidance in the valve shape that back flow in no area of the hollow body occurrence. This means that no vortices may arise, the vectorial Components have the main flow direction of the Oppose suspension.
  • FIG. 1 shows a valve device 1 according to the invention in Longitudinal section.
  • the valve housing 2 is shown schematically, which in the actual cavity 2.1 of the valve forms.
  • the valve housing 2 leads through a tangentially arranged feed 3 which the suspension is introduced and the flow in the cavity 2.1 so that a rotation component can be allocated.
  • the valve housing 2 narrows conically downwards and leads to an export opening 8.
  • a valve rod 4 is located along the longitudinal axis of the cavity 2.1 intended.
  • the valve rod 4 is slidable in the cover 5 of the Valve housing stored and caused by a more or less strong Insert into the conical area of the valve housing 2, one Change the flow cross-section and thus the desired one Throttling the flow.
  • a snap lock 7 attached On the valve housing 2 is a snap lock 7 attached, which in the closed state is sufficiently firm Establishes connection between the cover 5 and the valve housing 2.
  • the two snap locks 7 in the open position shown in dashed lines.
  • an actuating device 6 is indicated schematically ensures the movement of the valve rod 4. This can be done manually and way or by stepper motor drive or hydraulic happen.
  • the valve device 1 shown thus has a division, perpendicular to its longitudinal axis through which the upper parts of the Valve device together with the valve rod 4 from the valve housing 2 can be separated easily and quickly, making it easy Cleaning the valve interior and the lid area together can be done with the valve rod.
  • Figure 2 also shows a longitudinal section through an inventive Valve device 1.
  • the difference to the device from Figure 1 is in that the closure of the valve device by a Fork closure 7 is formed and an additional closing slide 3.1 is provided in the feed line 3.
  • the fork lock consists of two screws or bolts with one one-sided extension 7.1, which is based on the valve housing 2 are attached so that the fork 7.2 through a slot of the Lid top 5.1 can be pushed 'and' thus the lid 5 is firmly connected to the valve housing 2.
  • screws 7.1 used, the fork can be adjusted with different Pressure acts on the lid and thus a connection between the cover 5 and the valve housing 2 in the desired manner can be achieved.
  • a simple and quick release the lid by loosening the two screws 7.1 and Pulling out the fork 7.2 can be effected.
  • a slide 3.1 is provided in the feed line 3, through the actuation of the inflow of the stock suspension are blocked can and a flow of stock suspension during the Cleaning process can be prevented.
  • Figure 3 shows the device of Figure 2 in the disassembled state.
  • the Fork 7.2 with its slot 7.3 is on the left for clarity also shown in a top view.
  • FIG. 4 shows a somewhat more detailed view of the valve device 1 according to the invention, each with a section in the Level A-A and level B-B.
  • the valve 1 is with its valve housing 2, which shows the cavity 2.1.
  • the Valve housing 2 has a supply line 3 that is tangential is arranged and the feed suspension the desired Rotation component added. That is essentially cylindrical trained valve housing 2 tapers downwards and goes in the outlet opening 8 over.
  • On top of the valve body 2 is a flange-like bead attached, in the two screws 7.1 are screwed in.
  • the lid 5.1 fits into the opening of the Valve housing 2 and has a transverse slot, through which the fork 7.2 can be inserted so that it is on their ends is pressed down by the screws 7.1 and with their bearing surface, which leads through the slot of the cover 5, this with the valve housing 2 fixed.
  • An opening runs through the lid, through which the valve rod 4 can move in the longitudinal direction. Not corresponding sealants are shown here, of course are necessary to prevent fluid from escaping from the valve interior 2.1 to prevent.
  • an adjustment device 6 is through Screws 6.1 connected, with which the valve rod 4 manually or by another drive can be moved.
  • section A-A which is passed through the fork 7.2, the device is in Cross section recognizable and the position of the individual screws 7.1 and 6.1 better shown.
  • the tangential feed 3 is in this Top view also clarified.
  • FIG. 5 shows a ball valve 11 according to the invention in two Cuts.
  • the ball valve 11 has a housing 12, in the Cavity leads a supply line 13 and a discharge line 18.
  • in the A housing 17 of the ball valve 11 is provided with a thread 17, whose diameter is at least as large as the diameter of the inner ball 14 is.
  • the ball is with an adjustment device 16 connected so that the ball on the adjustment on a Axis is rotatably mounted.
  • the adjusting device 16 leads through Closure part 15, which on its lower side the shape of the ball is adjusted.
  • the ball 14 has a cylindrical passage 14.1 depending on the position of the ball 14 through the passage cross section the ball valve 11 opens more or less.
  • Section B-B shows the ball valve 11 in one slight throttle position by moving the ball 14 by 20 ° from its central position is rotated and thus leads to a throttling effect for the flow.
  • thread 17 provide other simple seat for the closure member 15.
  • a bayonet lock or a lock such as it is designed for the cover 5 in FIGS. 1 or 2 will.
