BRIEF SUMMARY
FIELD OF THE INVENTION
The present invention relates to an apparatus, particularly a combined control and regulating valve for liquids.
BACKGROUND OF THE INVENTION
Such valves are used e.g. in heating and cooling systems as well as in tap water systems and they are designed to regulate and cut off respectively a liquid flow, allow a measurement of the pressure difference, allow a discharge and/or filling of liquid and/or a temperature measurement. This valve suitably is designed to allow a presetting of the liquid flow, e.g. by means of the wheel, which is manually controlled or driven by a motor.
The valves used so far for this purpose are often very complicated and expensive to produce, assemble and mount as well as to handle. Also, the various functions are usually not present in one existing valve construction or they are distributed in a not advantageous way, which makes at least some part or a few parts of the valve difficult to access, since such valves often are mounted in positions which are difficult to access. Also, there may be an increased risk of leakage and above all it is difficult or impossible to optimize the known valves as to various combinations of purposes and differently conceived plants, i.e. it is difficult to adjust the known valves to varying needs in a quick and simple way.
Such previously known valves are exemplified in EP-A2-0221464, in which alternative functions are mentioned as such, but without any specific illustration or description. EP-A1-0153427 is a typical example of separately provided measuring and tapping/refilling connectors (FIG. 1). Despite common base or connector for these functions, this is the case as well with GB-A-1 110 157, in which a connector branch houses a shut-off or throttling valve, while a different connector branch may be connected to arbitrary apparatus.
SUMMARY OF THE INVENTION
The main purpose of the present invention is to counteract and as far as is feasible eliminate the abovementioned drawbacks and to develop an improved combined control and regulating valve, which above all is distinguished by an excellent flexibility and combination and adjustment possibilities respectively as well as by a simplified handling, particularly a more focused one, the risk of incorrect results and faulty applications being decreased or eliminated entirely. Other purposes of the invention is to generally develop the state of the art in this field and to suggest a generally advantageous valve having a long service life and reliable functions.
These purposes are obtained by designing an apparatus of the type described in the introduction.
BRIEF DESCRIPTION OF THE DRAWINGS
Additional characterizing features and advantages of the present invention are set forth in the following description, reference being made to the accompanying drawings, which show some preferred but not limiting embodiments of the invention:
FIG. 1 shows a combined control and regulating valve according to the invention in an axial diametrical section;
FIG. 2 also is an axial diametrical section of a differently designed embodiment of a portion of the valve shown in FIG. 1;
FIG. 3 shows an apparatus according to the invention in an axial diametrical section, which apparatus is connected to or part of a medium channel or the like;
FIGS. 4, 5 and 6, respectively, show in diametrical sections various examples of connections from a measuring portion to a medium channel or the like in line with special embodiments according to the invention.
DETAILED DESCRIPTION OF THE INVENTION
The valve shown in FIG. 1 is in its entirety designated 1. It comprises a housing 2 having a medium passage or the like 73 with an inlet 3 and an outlet 4 which, of course, may have reversed functions. A partition 5 between said inlet and outlet is provided with a main seat 6, with which a main valve body 7 cooperates, which is attached to the interior end of e.g. an outer spindle 8, on the exterior end of which e.g. an adjusting wheel 9 is disposed having a wheel screw 10, an O-ring 11, an indicating ring 12,
