Definitions
- the present invention is in the field of fluid flow control systems and more specifically it is concerned with valving and junction means for controlling fluid flow within supply lines and branching lines of a Fluid Distribution System (FDS).
- FDS Fluid Distribution System
- Consumers may be, for example, patients in a medical institute connected to an oxygen supply line, or a mechanical device or chemical process in which fluid is provided, e.g. a coolant fluid, a lubricant, a rinsing liquid or any chemical substance which may be required for carrying out a process.
- fluid e.g. a coolant fluid, a lubricant, a rinsing liquid or any chemical substance which may be required for carrying out a process.
- shutting off the main supply line might be extremely costly, e.g. in certain manufacturing processes where shutting off the supply line of a certain fluid entails halting the entire process.
- Restarting many processes requires purification of the supply system, which is a costly and time consuming procedure.
- An example of such a process is for example the manufacture of computer chips and the like, in which extreme purification conditions are required and any interference in the supply line e.g. adding a branching line, entails purification of the entire supply system.
- a junction element for a fluid delivery system comprising an inlet port for connecting to a main up-stream pipe section and an outlet port for connecting to a main down-stream pipe section, said outlet port being in flow communication with said inlet port; characterized in that the junction element is integrally fitted with at least one duct portion, each of the at least one duct portion being in flow communication with the inlet port or the outlet port and being integrally fitted with a valve member and having coupling means for coupling thereto a delivery element, whereby fluid flow through the duct portion may be shut off without interrupting the fluid flow through the main delivery pipe sections.
- the junction element is integrally formed with an up-stream pipe section and a down-stream pipe section, typically having a length suitable for connecting to an adjacent 3 down-stream pipe section or up-stream pipe section, respectively, or to an intermediate pipe section such as, for example, by orbital welding.
- the inlet port and the outlet port of the junction elements are each formed with a connecting end for connecting thereto a main up-stream pipe section and a main down-stream pipe section, respectively.
- the connecting end is a stub end fitted for orbital welding.
- valve member is adapted for sealing a respective duct portion extending between said delivery element and a cavity formed within said junction element; said cavity being in flow communication with the inlet port and the outlet port.
- a fluid delivery system for connecting one or more branch pipes to a main delivery pipe, said fluid delivery system being characterized in that the main delivery pipe is fitted with at least one junction element, each said junction element being integrally fitted with at least one duct portion, each at least one duct portion being in flow communication with the delivery pipe and is integrally fitted with a valve member and a coupling means associated with each duct portion, whereby fluid flow through the duct portion may be shut off without interrupting the fluid flow through the main delivery pipe.
- said junction element comprises an inlet port for connecting to a main up-stream pipe section, and an outlet port for connecting to a main down-stream pipe section, which pipe sections are integrally formed with the junction element.
- the inlet port and the outlet port of the junction element are each formed with a connecting end for connecting thereto a main up-stream section and a main down-stream section, respectively.
- valve member of the junction element is a ball-type valve.
- FIG. 1 is a perspective view of a junction element in accordance with the present invention comprising two branching outlets;
- Fig. 2 is a perspective view of the junction element seen in Fig. 1 where a delivery element is coupled to each of the outlets;
- Fig. 3 is an exploded isometric view of the junction element seen in Fig.2;
- Fig. 4 is a longitudinal cross-section of the junction element taken along line rV-IV in Fig. 2;
- Fig. 5 is a longitudinal cross-sectional view along line V-V in Fig. 2;
- Fig. 6 is a perspective view of a junction element fitted with two splitting devices at each of its branching outlets;
- Fig. 7 is an exploded view of a junction element fitted with another splitting device.
- Fig. 1 of the drawings illustrating a junction element generally designated 10 comprising a block-like housing member 11 fitted with an inlet port 12 and an outlet port 14 each fitted with a stub end 16 and 18, respectively.
- Stub end 16 is connected to a main up-stream pipe section 20 whereas stub end 18 is connected to a main down-stream pipe section 22.
- the stub ends 16 and 18 are connected to the respective pipe sections 20 and 22 by orbital welding or soldering, as known per se, although other types of weldings or connections are possible as well, in which case instead of a stub end there shall be provided a suitable connecting end, e.g. a clamping end, etc. 5
- junction element is symmetrical about the longitudinal axis extending through the main pipe sections and accordingly, for the sake of convenience, further reference will be made to one side of the junction element.
- these are only some examples selected out of many others.
- the housing member 11 is formed with a duct portion 28 transversely extending with respect to the main pipe sections 20 and 22 passing through a main cavity 30 of the housing, which cavity is intermediate the inlet 12 and outlet 14, whereby ducts 28 are in flow communication with the main supply line.
- Each of duct portions 28 extends towards a coupling end 32 of housing 11.
- a ball-type valve assembly 37 is integrally fitted within the housing 11 for controlling flow through duct 28.
- Each valve assembly comprises a ball-valve element 38 and a plurality of seals and packing rings generally designated 40 sealingly packed within a valve receiving portion 42 of the housing 11 and retained by threaded ring 41, as can be seen in Fig. 3.
- the valve is operable by a valve handle 44 fitted with lateral projections 46 and 48 adapted for engagement with a pin 50 projecting from the housing for limiting angular displacement of handle 44.
- the handle communicates with the ball-valve element 38 via stem 45 to which it is secured by nut 46.
- the valves are shown in their closed position, i.e. in which fluid flows through duct 28 is shut off. The artisan will have no difficulty in replacing the, ball-type valve assembly 37 with another type of valve.
- Coupling end 32 is a flanged member integrally extending from housing 11 and is adapted for coupling thereto a delivery element 65 (shown in Figs. 2, 3 and 5) and attachment thereto is carried out by means of bolts 66 and nuts 68.
- the coupling end may be of other types.
- the delivery element 65 serves for connecting a branching pipe (not shown) to pipe segment 70 integral with the delivery element 65, e.g. by orbital welding or otherwise, as known per se. 6
- junction element as illustrated in the figures is such that fluid flowing through the duct portions 28 may be shut off at any time without interrupting fluid flow through the main delivery pipe sections 20 and 22. This enables connection or disconnection of delivery distribution members, e.g. member 65, without having to first shut off fluid flow in the main line, but merely by closing valve member 38.
- Fig. 6 differs from the embodiment seen in Figs. 1 to 5 only in the delivery element generally designated 74 and accordingly, all like elements were given the same reference numerals as in the previous embodiment.
- the delivery member 74 is in fact a distribution element connected to the coupling end 32 by bolts 76 and nuts 68 as can readily be understood.
- Delivery element 74 is in fact a splitting device integrally fitted with two branching outlets generally designated 78 and 80, with a valve member (not seen) integrally and sealingly received within a respective valve housing 82 and 84 and operable by valve operating handle 86 and 88, respectively.
- Each of the outlets 78 and 80 is fitted with coupling means 32 similar to the arrangement illustrated with reference to Figs. 1 to 5, for coupling thereto a branch pipe 90 and 92 respectively, similar to the embodiment illustrated with reference to Figs. 1-3.
- Fig. 7 differs from the embodiment seen in Fig. 6 in that the delivery element 98 is formed with an additional outlet 100 to which another branching member 102 may be connected, the latter being integrally fitted with a valve member 104 and adapted for coupling to a branch pipe 106.
- Branching member 102 and delivery member 98 are connected to the housing 11 by bolts 108 extending through elements 102 and 98 and fastened by bolts 68 of coupling end 32 of the housing 11.
- Other components of this embodiment are similar or identical with those of the previous embodiments and accordingly it is presumed that the artisan will be familiar with their construction and operation. 7
- junction element in accordance with the present invention has some other significant advantageous as compared with heretofore known junction elements.
- One advantage is that owing to integration of the valve member within the housing provides minimal dead volume i.e., the volume of the duct 28 extending between the valve assembly end the cavity 30 of the housing. This is of particular importance in drainage and purification procedures, whereby a minimal amount of fluid is entrapped in said dead volume and so optimal drainage is obtained.
- junction element according to the invention maintains an essentially equal diameter through its length, thus ensuring essentially identical flow through the cross-section of the device.
