Especiall;~r in the case of~ heating circuit systems or in chemical process steps, however, it is crucial that such value; can be measured and displayed.
It is therefore the obj ect of the present invention to provide an improved device for producing pipe branches.
This object is accomplished by a generic device according to the features of claim 1.
Advantageous embodiments are described in the subclaims.
An inventive device for producing pipe branches includes a flowmeter for the fluid medium, located in the upper part of a clamp-on unit, as well as a temperature measuring device. As a consequence, generic devices will not be able to determine the flow rate and the temperature ofthe medium flowing within the system. Besides the determination of such parameters, suitable regulation of the flow rate and of the temperature of the fluid medium will also be possible.
In an advantageous embodiment ofthe invention, a display device for displaying the detected flow rate and temperature values is mounted on its upper part. This allows "in situ" reading of the measured values. Furthermore, it is possible to provide a f7owmeter and a temperature measuring device including suitable display means each at every branch ofthe medium-containing pipe. Tlvs will advantageously allow immediate detection of any differences occurring in the flow rates or in the temperatures prevailing.
In yet another advantageous embodiment ofthe invention, the upper part comprises an external pipe sleeve and an internal pipe accommodated within saidpipe sleeve.
Moreover, a valve disk is mounted on the end ofthe internal pipe facing the lowerpart, said valve disk being designed such that it engages with the corresponding lower aperture in said pipe such that the medium coming from the through passage wi 11 be contained within said internal pipe. Furthermore, the diameter of the internal pipe has been dimensioned such that a cavity is formed between the surface of the internal pipe and the internal surface ofthe pipe sleeve through which the fluid medium from the upper part is passed into said pipe. In this way, any medium coming from the branch or the through passage wi l l be forced to flow through the upper part of the clamp-on unit. The flowmeter is adva~~tageously provided within said internal pipe and the temperature measuring device is provided within said cavity. This allows exact measurement of the flow rate of the medium as well as of its temperature. Moreover, owing to the specific array of the flowmeter and the temperature measuring device, the device in its entirety can be kept relatively small.
The invention herein comprises measuring apparatus for measuring flow rate and temperature of a flowable medium, comprising an outer pipe jacket and an inner pipe disposed inside the outer pipe jacket, the diameter of the inner pipe being dimensioned such that a cavity is formed between the inner pipe and the outer pipe jacket, wherein a medium can flow into the inner pipe through an opening formed at a first end of the inner pipe, and at the second end of the inner pipe an opening is provided, through which the medium can flow out of the inner pipe and through the cavity out of the measuring apparatus, wherein a flowmeter and a temperature measuring device are arranged in and along this flow path for the flowable medium, respectively, formed in the measuring apparatus.
The invention herein further comprises an apparatus for producing one or more branches at a medium carrying pipe having a measuring apparatus according to any one of the preceding claims, consisting of a two-part unit clampable to the pipe, having a base portion and a top portion, wherein for each branch transverse to the pipe axis two opposed openings are formed in the pipe, and the base portion has a passage for the flowable medium, sealingly fitting to the lower opening, and the top portion has a valve insert fitting into the upper opening, and both portions are fixedly clamped to the pipe, wherein the measuring apparatus is disposed in the top portion.
Further details, features and advantages of the invention may be gathered from the description, which follows, of an embodiment illustrated in the (single) drawing.
The device 12 for producing pipe branches illustrated in a schematic sectional view in FIG 1 comprises a two-part unit 20 including a lower part 22 and an upper part 24 intended to be clamped on a pipe 10. For each branch, two opposing apertures 16, 18 are formed in the pipe 10 transverse to the pipe axis. The lower part 22 exhibits a through passage 30 for the 3a fluid medium which tightly fits on said lower aperture 18. The upper part 24, by contrast, exhibits a valve insert fitting in said upper aperture 16. The parts 22, 24 are interconnected by means of a hinge joint 80 and are clamped firmly on said pipe 10. The end of said unit 20 opposite said hinge joint 80 includes mounting means 14 for detachably interconnecting said lower and upper parts 22, 24.
As can be seen in FIG 1, the upper part 24 accommodates a flowmeter 26 for the fluid medium and a temperature measuring device 28. Furthermore, it is apparent therefrom that the upper part 24 includes a display device 32 for displaying the detected flow rate as well as temperature values. To be more precise, the upper part 24 consists of an external pipe sleeve 34 and an internal pipe 36 accommodated within said pipe sleeve 34. The diameter of said internal pipe 36 has been dimensioned such that a cavity 52 is formed between the surface of the internal pipe 36 and the internal surface of said pipe sleeve 34, through which the fluid medium is passed from the upper part 24 into said pipe 10. The end of the internal pipe 36 facing the lower part 22 includes a valve disk 38 which serves for engagement with the corresponding lower aperture 18 of said pipe 10. This serves to contain the medium from the through passage 30 within said internal pipe 36.
Said flowmeter 26 is provided within said internal pipe 36 and said temperature measuring device 28 is mounted within said cavity 52. To be more precise, the flowmeter 26 consists of a floating body 40 movably mounted within said internal pipe 36, which body 40 contacts a pressure spring 42 which in turn abuts a spring stop 44 within said internal pipe 36 at the end opposite said floating body 40. This pressure spring 42 exerts a spring force acting against the direction of flow of said medium. It may furthermore be gathered from the drawing that said floating body 40 is connected to a pointer 48 of the display device 32 so as to allow the current flow rate to be read therefrom.
The temperature measuring device 28 comprises a thermometer 78 including a thermometer tube 54 and corresponding receiving and fixing means 58 for mounting said thermometer 78 within said cavity 52. The display device 32 moreover includes a memory pointer 56 for marking the temperature value measured by the temperature measuring device 28.
It may furthermore be seen from the drawing that a rotary handle 62 is formed at the end of the upper part 24 facing away from said pipe 10, said handle 62 actuating a spindle 60 which in turn engages with said internal pipe 36 and is tightly connected thereto via a sealing ring 70. Actuation of said rotary handle 62 will cause said valve disk 38 to go up and down.
A cap-like safety cover 66 partially overlapping said rotary handle 62 will prevent unintended damage to the rotary handle 62 and/or the entire valve insert in the upper part 24.
Furthermore, it is apparent from the drawing that a plurality of seals 68, 70, 72, 74, 76 are provided to ensure the sealing connection of the individual components of the device 12. In addition, it is notable from the drawing that plural spacers SO are provided within said cavity 52 for maintaining the distance between the surface of the internal pipe 36 and the internal surface of the pipe sleeve 34.
The device 12 for producing pipe branches is usually made of metal or a metal alloy.
However, it is also possible to use any other kind of suitable material such as plastic, glass or the like for manufacturing the individual components of the device 12.
This object is accomplished by a generic device according to the features of claim 1.
