Definitions
- the invention relates to a pressure limiter with an interior which is connected to an environment and is delimited by a sleeve which can be displaced along a guide.
- pressure limiters are used, for example, for sanitary water supply and are previously known from practice in various embodiments.
- the pressure limiters can also be referred to as pressure relief valves and can be used to set the pressure in water-bearing systems to a specific limit value.
- the operating pressure inside the water-carrying system is related via the movable sleeve to an ambient pressure against a restoring force in order to limit the pressure in this way.
- the ambient pressure serves as a reference pressure.
- Pressure limitation with reference to ambient pressure is a feature that distinguishes a pressure limiter from a flow controller.
- the object of the invention is to provide a pressure limiter of the type mentioned, which can also be used reliably for pressure limitation in such water-bearing systems in which contamination by Particles, for example by grains of sand, is to be feared.
- the guide comprises guide projections which are arranged on a base body of the pressure limiter which is spaced apart from an inner wall of the sleeve, the guide projections forming guide surfaces which face the sleeve, in particular the inner wall of the sleeve, which can be directed in at least one direction or in have a cross-sectional reduction in both directions of the sliding movement of the sleeves.
- the cross-sectional tapering of the guide projections can be formed on the inflow side and/or on the outflow side.
- the cross-sectional constrictions can divert particles, such as grains of sand, laterally, so that they do not get into an intermediate space between the guide surface and the inner wall of the sleeve.
- the cross-sectional constrictions are terminated by a radius.
- Each guide projection can have a cross-sectional tapering with such a radius on the inflow side and/or on the outflow side.
- Cross-sectional tapering can be minimized or even completely avoided transversely to the direction of movement of the sleeve relative to the guide projections or contact surfaces on which particles prefer could accumulate.
- each of the guide projections of the guide has a diamond shape in cross section and/or in plan view.
- each of the guide projections of the guide has two cross-sectional tapers, which in cross section and/or in top view can each be formed from half of a rhombus, in particular from a triangle.
- tips of the diamond shape of the guide projections have an opening angle of less than 90° in the direction of the displacement movement, in particular on the inflow side and/or on the outflow side.
- the cross-sectional tapers have an acute angle, which promotes the previously described lateral deflection and/or displacement of particles that may be contained in the watercourse.
- edges between the guide surfaces facing the sleeve and the lateral boundary walls of the guide projections are formed with sharp edges.
- a sharp edge at the transition between the respective guide surface and lateral boundary walls of the guide projections can prevent particles that have been deflected sideways due to the shape of the guide projections from still moving onto the guide surface and thus impairing the guidance of the sleeve.
- the sleeve can against a restoring force of a Restoring means, in particular a restoring spring, can be moved from an open position into an at least partially closed position.
- the restoring means can be arranged between the base body and the sleeve of the pressure limiter.
- the pressure limiter can be inserted or interposed in a fluid line, in particular in a water line.
- the interior of the pressure limiter can be or will be limited by the sleeve, which can also be referred to as the valve body.
- the sleeve inner wall can be cylindrical.
- the guide surfaces can be coaxial with the inner wall of the sleeve, and in particular can have a convex curvature. This can promote good contact between the inner wall of the sleeve and the guide surfaces, and thus reliable guidance of the sleeve. The good contact between the sleeve and the guide surfaces also prevents particles from getting between the inner wall of the sleeve and the guide surfaces.
- the pressure limiter can have, in particular in its main body, a through-flow channel which comprises at least one channel opening.
- the at least one channel opening can be closed at least partially by the sleeve to limit the pressure. If the pressure in the line section downstream of the pressure limiter increases, the sleeve, which can be displaced along the guide, can be moved under the pressure of the medium flowing through from an open position, in particular against the restoring force of the previously mentioned restoring element, into a closed position. In this closed position, the sleeve can at least partially close the channel opening of the at least one flow channel.
- the pressure in the line section downstream from the pressure limiter can be limited to a specific maximum value.
- guide projections which are arranged at a distance from a mold parting line, stand at an angle on a base, in particular on the base body, so that they are aligned in the demolding direction. This enables the joint demolding of the guide projections, which are preferably arranged offset uniformly in the circumferential direction on the outside of the base body.
- Figure 1 is an isometric view of a
- the pressure limiter comprises a base body in which a flow channel is formed, and a sleeve that is slidably guided along a guide on the base body, the guide having a plurality of diamond-shaped guide projections arranged uniformly on the outer circumference of the base body,
- FIG. 2 shows the detail marked with the circle K in FIG. 1 in an enlarged representation
- Figures 35 Side views of the pressure limiter shown in the previous figures in the open position ( Figure 3), in an intermediate position ( Figure 4) and in a partially closed representation, in which the sleeve partially closes channel openings of the flow channel in the base body and thus a flow through the pressure limiter in comparison halved to the position of the sleeve shown in Figure 3,
- FIGS 6-8 sectional side views of the pressure limiter shown in Figures 3 to 5
- FIG. 9 11 isometric views of the pressure limiter shown in Figures 3 to 8,
- Figure 12 is a side view of the pressure limiter
- Figure 13 is a sectional view of the pressure limiter along the line labeled XIII-XIII in Figure 12,
- Figure 14 is a sectional view of the pressure limiter
- Figure 15 is an exploded view of the pressure limiter
- FIG. 16 shows an isometric representation of the main body of the pressure limiter.
- the pressure limiter 1 comprises a pressure limiter 1 in the position of use via a connection, for example an opening and/or bore interior 2 connected to an environment.
- the pressure limiter 1 can be flown through in the direction of the arrow Pfl and can be used or interposed in a water pipe, for example, in order to limit the water pressure in a line section downstream from the pressure limiter 1 to a specified maximum value.
- the pressure limiter 1 can also be referred to as a pressure reducing valve.
- the interior space 2 is delimited by a sleeve 4 that can be displaced along a guide 3 .
- the guide 3 comprises a plurality of guide projections 5 which are arranged on a base body 7 of the pressure limiter 1 which is spaced apart from a sleeve inner wall 6 of the sleeve 4 .
- the figures make it clear that the guide projections 5 are distributed uniformly on an outside of the base body 7 of the pressure limiter 1 .
- the guide projections 5 form guide surfaces 8 which face the sleeve 4 and are provided with cross-sectional tapers 9 in both directions of the displacement movement of the sleeve 4 .
- the cross-sectional tapers 9 each have a radius 10 at the end, by which they are closed.
- FIGS. 2 and 16 make it clear that the guide projections 5 have a rhombic shape in cross section or in a plan view. Inflow-side and outflow-side tips 11 of the diamond shape or tips 11 in the direction of the sliding movement are provided with an opening angle of less than 90°.
- FIG. 2 also shows that edges 17 between guide surfaces 8 facing sleeve 4 and lateral boundary walls 12 of guide projections 5 are formed with sharp edges. The sharp-edged edges 17 prevent that by the shape of the guide projections 5 laterally derived particles still on the
- FIGS. 6 to 8 and 15 show that the sleeve 4 can be moved from an open position into an at least partially closed position against a restoring force of a restoring means 13, here a restoring spring.
- the restoring means 13 is here arranged between the base body 7 and the sleeve 4 .
- the pressure limiter 1 can be inserted into a housing not shown in the figures.
- the housing can have at least one corresponding thread in order to insert the housing with the pressure limiter 1 into a line and/or to interpose between two line sections.
- the housing can have a connection, in particular a line and/or a bore, via which the interior 2 of the pressure limiter 1 arranged inside the housing can be connected to the ambient pressure.
- the pressure limiter 1 has a flow channel 15 formed in its base body 7 .
- the flow channel 15 has two channel openings 16 which can be closed at least partially by the sleeve 4 to limit the pressure.
- the sleeve 4 which is slidably guided along the guide 3, is moved under the pressure of the medium flowing through from an open position shown, for example, in Figure 3 against the restoring force of the restoring element 13 into a partially closed position, shown, for example, in Figure 5 position moved. In this partially closed position, the sleeve 4 closes the two channel openings 16 of the flow channel 15 at least partially.
- the sleeve 4 Since the sleeve 4 is increasingly pressed in the direction of the base body 7 against the restoring force of the at least one restoring element 13 when the fluid pressure in the line section downstream from the pressure limiter 1 increases, and the pressure loss at the channel opening 16, which is thereby becoming smaller, increases, the pressure of the fluid in limited to a specified maximum value in the line section downstream from the pressure limiter 1.
- Figures 3, 6 and 9 show the sleeve 4 in its open position relative to the base body 7 of the pressure limiter 1.
- Figures 4, 7 and 10 show the sleeve 4 of the pressure limiter 1 in an intermediate position in which the flow through the pressure limiter 1 is already is somewhat limited. In this intermediate position, the sleeve 4 is already lying on the guide surfaces 8 of the guide projections 5 .
- FIGS. 5, 8 and 11 show the pressure limiter 1 with the sleeve 4 positioned in a partially closed position. In this position, the sleeve 4 closes the channel openings 16 to the maximum extent. As a result, the flow through the pressure limiter 1 is limited to half the flow that the pressure limiter 1 permits when the sleeve 4 is in the open position shown in FIGS. 3, 6 and 9 relative to the base body
- the sleeve inner wall 6 is cylindrical and the guide surfaces 8 are curved and coaxial with the sleeve inner wall 6 .
- Figure 13 shows that guide projections 5, which are located away from a tool parting line 18, are inclined on a base, namely on the base body 7, so that they are aligned in the demolding direction. This enables the joint demoulding of the guide projections 5 arranged uniformly offset in the circumferential direction on the outside of the base body 7 and can simplify the manufacture of the pressure limiter 1 .
- the invention deals with improvements in the technical field of pressure limiters 1, such as are used in particular in sanitary water supply systems. So that the pressure limiter 1 can also be used reliably in water-carrying systems in which contamination of the watercourse by particles, for example grains of sand, is to be expected, the pressure limiter 1 has guide surfaces 8 which, in at least one direction, prevent a displacement movement of a sleeve 4 of the pressure limiter 1 have a cross-sectional reduction 9 .
