Definitions
- the invention relates to a naturalflußeinstellventil with a valve housing having a flow channel and a standing at an angle to the flow channel, wherein in the flow passage, a throttle device is arranged, which has an operable through the nozzle throttle element, and with two measuring points for detecting the Pressure in the flow channel on both sides of a throttle assembly, each of which is connected via a pressure measuring with a pressure measuring.
- Such congestive is known for example from DE 196 19 125 C2.
- the throttle arrangement is formed here by a measuring socket, which is connected upstream of the actual throttle device.
- the branching off on both sides of this Meßbuchse Druckmeßkanäle are led out laterally, so that the Druckmeßan say are arranged in side surfaces of the valve housing and the neck at an angle of about 45 ° and each other at an angle of 90 °.
- Such a flow adjustment valve serves to hydraulically balance a hydraulic system, for example a pump-operated hot water heater. By adjusting one would like to achieve that the flow rates in different sections of the liquid-filled system correspond to certain specifications.
- the pressure is determined on both sides of the throttle arrangement. If the size of the throttle assembly is known, one can calculate from the pressure of the flow. With the help of the throttle device, the flow can be changed. It is also known to use the throttle device as a throttle arrangement. In this case, you still need a scale or other display device with which you can read the current opening degree of the throttle device.
- Such fürflußeinstellventil is rarely actuated, usually when commissioning such a hydraulic system or changes in the hydraulic system. So that it does not bother otherwise, it is often mounted in inaccessible places, for example, under ceilings or in shafts. As a result, however, the adjustment of the flow for a mechanic is difficult because the fürflußeinstellventil is difficult to access. In particular, it is often difficult to introduce probes in the Druckmeßan until. This sometimes requires a considerable skill of the fitter.
- the invention has for its object to expand the design options in a fürflußeinstellventil.
- the nozzle may be wholly or partially formed as part of the valve housing. It is also possible to use as a nozzle a separate element, which is connected to the valve housing.
- the nozzle can also be designed in several parts, wherein the parts in the axial and / or radial direction (relative to the nozzle) or in the circumferential direction can be assembled.
- an insert is arranged in the nozzle and the pressure measuring channel is formed over at least part of its length between the insert and a nozzle wall. Machining the nozzle itself is often no longer necessary, apart from an opening that may penetrate the nozzle wall, so that the pressure can be passed to the outside.
- the insert carries the throttle element.
- the insert is thus carried out for two purposes, namely once for the formation of the pressure measuring and on the other hand for holding the throttle element.
- the Druckmeßan somebody are arranged in each case a Meßstutzen and both Meßstutzen parallel to each other.
- the Meßstutzen include an angle in the range of 20 ° to 70 ° with the neck.
- the Meßstutzen can thus be arranged in the region between the nozzle and the housing, which surrounds the flow channel in this area. Since the fitter on the anyway Must be able to access nozzle to operate the throttle element, it is assumed that in this area, the pressure measuring terminals are accessible to introduce a probe can.
- the Meßstutzen are directed in a gusset between the nozzle and a flow channel surrounding the longitudinal portion of the valve housing.
- the Naturalflußeinstellventil is therefore kept very compact from the outside. All the elements projecting laterally from the valve body go from one point, so to speak. This also keeps the danger of being caught on the measuring stub.
- the nozzle is arranged at least over part of its length between the two pressure measuring channels. So you use the nozzle also for separating the two pressure measuring channels from each other. Other components are not required. This simplifies the design of the valve housing.
- At least one pressure measuring connection is arranged in a connection element which is held rotatably on the connection piece. This makes it possible to rotate the Druckmeßanschluß relative to the nozzle and bring in a position that is favorable for attaching a pressure measuring probe. This further facilitates the handling.
- the connecting element is designed as a spout which engages around the neck.
- the spout thus forms a kind of cuff, which surrounds the neck ring.
- the nozzle then forms a pivot bearing for the spout, so that there is a mechanically relatively strong construction.
- annular channel is formed between the nozzle and the nozzle.
- the annular channel forms part of the pressure measuring channel.
- the annular channel can ensure that the fluid under pressure regardless of the rotational position of the nozzle relative to the nozzle can always get to the pressure measuring connection.
- annular channel is formed between the spout and the valve housing in the region of an end face of the spout.
- This annular channel so to speak the second annular channel, then forms part of the pressure measuring channel from the other pressure measuring connection.
- the annular channel is bounded by an outer wall of the nozzle.
- the second annular channel is therefore located in a gusset between the nozzle and the remaining part of the valve housing, so that these two elements already form two boundary walls of the annular channel.
- the remaining boundary of the annular channel is then formed by the spout itself.
- Fig. 2 shows a section l-l with partial section H-II of FIG. 1 and
- FIG. 3 shows a section l-l with a partial section IH-III of FIG. 1st
- a Humanflußeinstellventil 1 has a valve housing 2, through which a flow channel 3 with an inlet 4 and an outlet 5 extends. The direction of flow can also be reversed. Between the inlet 4 and the outlet 5 a throttle device 6 is arranged, which is a long 7 has an adjustable throttle element 8 has an axis. The throttle element 8 is displaceable by an adjusting spindle 9, which is rotatable for this purpose in a screw thread, not shown.
- the valve housing 1 has a connection piece 10, which is arranged approximately at right angles to a longitudinal section 11, the longitudinal section 11 extending parallel to the flow channel 3.
- the nozzle 10 initially has the task to store the throttle element 8.
- the throttle element 8 is received in an insert 12 which is inserted into the neck 10.
- the insert 12 is sealed relative to the nozzle 10 so that no liquid can pass out of the flow channel 3 to the outside.
- the throttle device 6 forms, with the aid of the throttle element 8, a flow cross section 13 which can be varied in order to set a desired flow through the flow adjustment valve 1.
- both sides of the throttle device 6 each have a measuring point 14, 15 are provided.
- At each measuring point 14, 15 of the pressure prevailing in the flow channel 3 at this point pressure can be measured. From the pressure difference, which is then available through this measurement, and information about the size of the flow cross-section 13 can then calculate the flow.
- two Druckmeßan getting 16, 17 are provided, each of which is arranged in a Meßstutzen 18, 19. Both Meßstutzen 18, 19 are part of a formed as a spout 20 connecting element, which is rotatably mounted on the nozzle 10. Between the spout 20 and the nozzle 10, two seals 21, 22 are arranged. Another seal is located between the spout 20 and the longitudinal portion 11 of the valve housing. 2
- the measuring point 14 is connected via an opening 24 in the valve housing 2 with an annular channel 25 which is bounded by the spout 20, the valve housing 2 and the nozzle 10.
- the pressure measuring connection 16 opens into the annular channel 25 and regardless of which angular position the Tül- Ie 20 to the nozzle 10 has.
- the other measuring point 15 is connected via a channel 26 which extends parallel to the axis 7, with an annular channel 27 which is connected to the other pressure measuring connection 17.
- the nozzle 10 can also be formed in several parts, at least in the region of the channel 26, wherein a first part is firmly connected to the valve housing 2 or even integrally formed and another part is inserted into the first part or surrounds the first part ,
- the channel 26 is formed between the insert 12 and the nozzle 10.
- the nozzle 10 is formed of a plurality of parts with a nozzle part 28 which is part of the valve housing 2 and projects from this at right angles, and with a nozzle part 29 which is connected to the nozzle part 28, as is known per se.
- the channel 26 is also formed as an annular channel surrounding the insert 12. Since the channel 26 is located within the nozzle 10, a seal to the outside is initially not required here. The annular channel 27, however, is sealed by the two seals 21, 22.
- the two Meßstutzen 18, 19 are arranged parallel to each other. Accordingly, the two Druckmeßan say 16, 17 parallel to each other. They are closed by caps 30, 31. To perform a measurement, it is only necessary to remove the two caps 30, 31. Measuring probes, not shown in more detail, which are connected to a common axis ter are attached, can then be used with a movement by the fitter in the Druckmeßan say 16, 17. So it is only a handling operation required, which greatly facilitates the work of the fitter, especially if the fürflußeinstellventil is located in inaccessible places.
- the spout 20 on the spigot 10 may be rotated to find a more favorable position for insertion of the probes into the pressure sensing ports 16, 17.
- the two Meßstutzen 18, 19 halve approximately the angle between the nozzle 10 and the longitudinal portion 11 of the valve housing 2.
- the angle that the Meßstutzen 18, 19 occupy is not set to 45 °. It can be anywhere in the range of 20 ° to 70 °.
- the two Meßstutzen 18, 19 are directed so that they protrude into the gusset, which is formed between the longitudinal portion 11 of the valve housing 2 and the nozzle 10.
- the throttle element 8 protrudes into a channel 30 which is formed with a ball element 31.
- the ball element 31 is rotatable about the axis 7 in order to completely close the flow channel 3.
- the portion of the system, through which the flow is adjusted also be shut off, for example, for maintenance purposes.
- the ball member 31 is held by a ring insert 32 having in its peripheral wall openings 33 through which the measuring point 14 is supplied with pressure.
