Definitions

  • valvemember Valve with a herical spring as valvemember
  • the present invention relates to a valve for closing or controlling a fluid flow.
  • Many different constructions of valves for closing or con ⁇ trolling fluid flows are previously known.
  • the object of the present invention is to provide a new valve which has a larger field of application, is easier and cheaper to manufacture and is in certain respects also better than the previously known valves.
  • the valve according to the present invention is characterized in that the variable passage area is con ⁇ stituted by the area between the convolutions of a helix.
  • this is provided with means for reducing the pressure drop of the fluid flow when this flows through the area between the convolutions of the helix.
  • the generation of vibrations and noise in the valve caused thereby are obstructed, which vibrations can arise at great pressure drops over the helix.
  • the valve can be designed so that the convolutions of the helix directly engages each other when the valve is closed, but especially when the valve is designed as a shut-off valve it is preferred to form the con ⁇ volutions of the helix from rubber or another material.
  • the characteristic of the valve i.e. the variations of the passage area in relation to the distance between the ends of the helix, can be given substantially any desired function, for example by forming the helix as a conical helix, or by changing the cross sectional size of the con ⁇ volutions of the helix at different portions thereof.
  • the helix is provided in a passage-way ofthe valve body of a tap or ball valve in order to provide in the valve a flow control device which is activated when the valve is opened.
  • a combined shut-off and flow control device for for example water pipe .systems.
  • Fig. 1 is a sectional view of a valve according to the invention.
  • Fig. 2 is a sectional view corresponding to Fig. 1 of an other embodiment of the valve according to the invention.
  • Figs. 3a and 3b show different positions of a valve according to the inventio intended to be used as a flow control device.
  • Fig. 4 shows a valve according to the invention designed as a check valve.
  • Fig. 5 shows a further embodiment of a valve according to the invention designed as a flow control device.
  • Fig. 6 is an axial section of a tap valve includin a valve according to the invention.
  • Fig. 1 is an axial section of a valve according to the invention, the device being connected with a pipe 2.
  • the control element of the valve is constituted by a helix 4 having one end connected with a shoulder 6 of the pipe 2 and supporting at its other end a pressure plate 8.
  • the pressure plate 8 constitutes a flow resistance having a predetermined passage area.
  • the fluid flow through the pipe 2 takes place in the direction of the arrows, and thus, the fluid flows between the convo- lutions of the helix. Thereby, the helix will determine the passage are of the valve in dependency of the area between the convolutions.
  • the flow of fluid through the pipe actuates the pressure plate 8 which is exposed to a greater pressure from the fluid when the fluid flow is in ⁇ creased, so that the plate 8 is forced to the right which in turn bring about a compression of the helix 4.
  • the compression of the helix 4 provides for a reduction of the passage area between the convolutions of the helix in turn providing for a throttling of the fluid flow.
  • the helix forces the pressure plate 8 to the left in the figure, so that the passage area between the convolutions of the helix is increased and also the fluid flow is thereby increased.
  • the valve according to Fig. 1 is suitable for being used as an auto ⁇ matic shut-off valve which is actuated at an unusually great flow through the pipe 2, for example because of a pipe fracture down-stream from the flow control device. If such a pipe fracture takes place, the helix 4 will be compressed to a closed position and will be maintained in this position because of the pressure difference in the pipe at each side of the flow control device.
  • Fig. 2 shows an automatic flow control device which is included in a pipe 10.
  • a plate 12 firmly connected with the pipe wall and supporting one end of a helix 14. Radially out ⁇ side the helix 14, the plate 12 is provided with passage openings 16.
  • the helix supports a pressure plate 18, which is guided for an axial movement in the pipe 10.
  • the plate 18 is provided with a central inlet opening 20.
  • the plate 12 as well as the plate 18 form flow resistances having predetermined passage areas for reducing the pressure drop over the helix 14. If said pressure drop is too great, there is created vibrations in the helix in turn leading to noise.
  • the flow control device according to Fig. 2 works according to the same principles as the device according to Fig. i.
  • the flow control device maintains a constant flow in the pipe by the fact that the passage area between the convo ⁇ lutions of the helix is reduced when the flow and the pressure on the plate 18 increase so that the flow is again reduced and vice versa.
  • Figs. 3a and 3b show a flow control device corresponding to the device of Fig. 2 ' positioned in a pipe 22.
  • the control device according to Figs. 3a and 3b comprises a plate 24 supporting a helix 26 and being formed with passage openings 28 peripherally outside the helix.
  • the helix 26 supports a pressure plate 30 having a central passage opening 32.
  • the plates 24 and 30 constitute flow resistances having predetermined passage areas for reducing the pressure drop over the helix 26.
  • the flow control device according to Figs. 3a and 3b differs from the flow control de- vices according to Figs. 1 and 2 by the fact that the helix is conical.
  • the helix By forming the helix in a suitable way with regard to the diameter of the convolutions and/or the sectional size of the convo ⁇ lutions at different positions of the length of the helix, it is possib to provide a flow control device having any desired characteristic.
  • the plate 24 is provided with a central opening 33 having a relatively smal diameter which provides for a more even passage of the fluid through the control device and obviates the closing of the flow control device at pressure shocks.
  • Fig. 4 shows a device according to the invention which is designed as a check valve.
  • the valve is provided in a pipe 34 and comprises a plate 36 connected with the pipe and having one end of a helix connected thereto. The other end of the helix supports a plate 40.
  • the plate 36 has a central passage opening 42.
  • the plate 40 has less outer diameter than the inner diameter of the pipe 34 for which reason there is formed an annular passage opening 44 around the plate 40.
  • the flow directions through the valve are shown by means of arrows.
  • a fluid flow through the valve in the directions of the arrow forces the plate 40 to the right according to Fig. 4, so that the helix 38 is retained in an extracted position and the fluid flow takes place between the con ⁇ volutions of the helix. If the fluid flow takes place in the opposite direction or the fluid flow terminates, the plate 40 is moved to the left in Fig. 4 in dependency of the strength of the helix so that the area between the convolutions is closed and a flow in the opposite direction is thereby obstructed.
  • Dependent on the pretensioning of the helix 38 in the direction of contracted position it is possible to provide for an opening of the valve at any desired flow in the direction to the right or to provide for a closing at any desired flow in the di- rection to the left in the figure.
  • the flow control device shown in Fig. 5 comprises a valve housing 46 having an annular projection 48 and a locking ring 50 positioned in a groove in the housing.

  • the flow control device includes a flow resistance having a variable passage area.
  • the flow resistance having a variable passage area comprises a valve means 58 and a valve seating 62 constituted by a conical element 60.
  • the element 60 is by means of an edge flange 64 fixed between the helix 52 and the projection 48.
  • the valve means 58 is supported by the washer 54 and is moved together therewith, as the washer 54 is moved more or less to the left according to Fig. 5 dependent on the passage of the fluid through the flow control device.
  • Dependent on the position of the washer 54 and thereby of the valve means 58 in relation to the valve seating 62 the passage area through the flow resistance having a variable passage area will variate.
  • the flow resistance having a predetermined passage area and the flow resistance having a variable passage area cooperate for maintaining a substantially constant pressure difference over the helix 52 at different flow rates. Thereby, vibrations of the helix 52 and noise accompanying said vibrations will be quite elimi ⁇ nated in the valve.
  • the flow control device according to Fig. 5 includes an extremely well developed control technique, the device consists of simple elements which in a fast and easy way can be mounted without use of screws or other fastening means requiring time for its mounting. This fact is a great advantage.
