[0007] Quick venting adapter for testing the functionality of a manometer and method for venting a manometer mounted on a fitting
[0008] The invention relates to a quick-vent adapter for testing the functionality of a pressure gauge, comprising a connection part with a connection nozzle for fluid-conducting connection to a pressurized component, wherein the connection nozzle has a pressure inlet, and a pressure gauge part arranged on the connection part and movable relative to the connection part, with a pressure gauge interface for fluid-conducting coupling to a pressure gauge. The invention further relates to a fitting, in particular a fire extinguishing system valve, and a method for venting a pressure gauge arranged on a fitting using a quick-vent adapter.
[0009] Rapid venting adapters are known in the art and are frequently installed as an intermediate component between, for example, a pressure vessel and a pressure gauge mounted on it. To check the functionality of the pressure gauge, it is depressurized at predetermined intervals using the rapid venting adapter. This is typically achieved by interrupting the pressure supply to the pressure gauge and establishing a connection from the pressure gauge to the surrounding environment.
[0010] From FR 2 240 446 B1, for example, a quick-test fitting for a pressure gauge is known, which has a connection part with a connection nozzle for fluid-conducting connection to a pressure vessel. The pressure gauge is coupled to the connection part via a pressure line. Along a section between a pressure inlet on the connection-
[0011] A valve body is arranged between the terminal and the pressure gauge. This valve body is actuated by a push button, interrupting the fluid connection from the pressure vessel to the pressure gauge and opening a vent port on the terminal. When the vent port is opened, the pressurized fluid in the pressure line escapes into the environment. The vent port is positioned in such a way that the escaping fluid flows along the push button. This can pose a hazard to the user if the fluid in the pressure vessel is aggressive or at high or low temperatures.
[0012] From CN 2089625 U, a test fitting is known by means of which a pressure gauge, which is unpressurized in its normal operating position, is fluid-conductingly connected to a pressurized container in order to measure the pressure inside. The fitting has a connection part with a connecting nozzle for fluid-conducting connection to the pressurized container. Furthermore, the test fitting has a pressure gauge part that is movable relative to the connection part, on which the pressure gauge is arranged and which is held in the normal operating position by a compression spring. By applying a compressive force axially to the connection part, the pressure gauge part is brought into a pressure-conducting connection with the pressure gauge to indicate the pressure in the container. However, to move the pressure gauge part, a user must exert a compressive force on the pressure gauge itself, which may make it difficult for them to read the exact pressure on the gauge.
[0013] In both of the solutions described above, a comparatively large amount of the pressure medium can escape into the environment under unfavorable circumstances, for example from the pressure line connecting the manometer to the test fitting or when moving the manometer part into or out of the fluid-conducting connection with the pressure vessel.
[0014] Therefore, the present invention was based on the objective of providing a rapid venting adapter that simplifies and makes the performance of functional testing more reliable. Furthermore, there is a need for a rapid venting adapter that minimizes the amount of pressurized medium escaping when the pressure gauge is depressurized.
[0015] The invention solves the underlying problem according to a first aspect in a rapid venting adapter for testing the functionality of a manometer mounted thereon with the features according to claim 1.In particular, the adapter has at least one pressure channel extending from the pressure inlet towards the manometer interface and one vent channel extending from the manometer interface to the environment, wherein the manometer part is arranged to be moved back and forth between a first rotary position releasing the pressure channel and a second rotary position releasing the vent channel, wherein the manometer part has a closing surface for the pressure channel which, in the moving position, is subjected to an inflow direction defined by the pressure channel at the connection part, and wherein the manometer part is supported at the connection part against the inflow direction and is movably mounted at the connection part in a plane inclined at an angle greater than 70°, preferably perpendicular to the inflow direction.
[0016] According to the invention, the manometer section, which is mounted on the connection part at an angle in a plane, in particular perpendicular to the flow direction, implements a design solution by means of which the functional testing of a manometer mounted on the quick-vent adapter can be carried out in a simplified yet reliable manner. With the movable design of the manometer section relative to the connection part according to the invention, improved force decoupling from a pressure acting within a system is achieved by means of the movement of the manometer section at an angle to the flow direction, which allows the manometer section to be moved relative to the connection part with less force overall.Furthermore, when the manometer section is moved from its first position, which is inclined at an angle greater than 70° in a plane, preferably transversely to the flow direction acting on the sealing surface of the manometer section, the direct fluid-conducting connection between the manometer at the quick-vent adapter and the pressure channel is severed after only a short distance. This significantly reduces the amount of pressurized medium that escapes through the vent channel when the manometer section is moved to its second position, which releases the vent channel, due to the minimized pressure chamber within the quick-vent adapter. Preferably, the manometer section is moved perpendicular to the flow direction at the connection point, which approximately corresponds to the direction of extension of the pressure channel at the connection point.
[0017] According to a preferred embodiment of the rapid venting adapter, the first movement position defines a pressure transmission position, and the second movement position defines a venting position. The pressure gauge section is configured to release only the pressure channel in the pressure transmission position and only the venting channel in the venting position. With this inventive design of the rapid venting adapter, a direct fluid-conducting connection between the pressure inlet on the connection part and the venting channel on the adapter is not permitted at any point during the movement of the pressure gauge section between the first and second movement positions. This preferably prevents uncontrolled escape of the pressurized medium from the adapter.Preferably, the manometer section is rotated by an angle of approximately 90° to move from the first to the second position. This rotation angle alone creates a structural separation between the pressure channel formed at the connection point and the vent channel.
[0018] According to a preferred embodiment of the rapid venting adapter, the pressure gauge section has an intermediate position between the first and second movement positions, in which both the pressure channel and the vent channel are blocked. In particular, the adjustable intermediate position on the rapid venting adapter ensures that the pressurized medium remaining in the pressure channel cannot flow towards the vent channel. Preferably, a sealing element interacts with the pressure gauge section, which is rotatably mounted on the connection part, in this intermediate position such that the pressure channel is permanently sealed against the vent channel. The intermediate position is preferably defined within an angular range of approximately 35° to 40°, particularly at approximately 37.6°, starting from the first movement position, in which the vent channel is completely blocked.The intermediate position range is preferably defined from the second movement position in an angular range of approximately 50° to 55°, in particular at approximately 52.4°, in which the pressure channel is completely blocked.
[0019] In a preferred embodiment, the pressure gauge section is rotatably or slidably mounted on the connection section. This rotatable or slidable mounting of the pressure gauge section on the connection section provides a simple means of adjusting the pressure gauge section in a plane at an angle greater than 70° to the flow direction on the connection section, which is directed towards the sealing surface of the pressure gauge section. In a preferred embodiment, the pressure gauge section is rotatably mounted on the connection section in a plane at the specified angle to the flow direction and, in particular, to the pressure channel defining the flow direction. An alternative embodiment provides that the pressure gauge section is inclined in a plane, preferably perpendicular to the flow direction and, in particular, to the pressure channel defining the flow direction, and is slidably mounted relative to the connection section.A further development of the rapid venting adapter provides that the connecting part has a receptacle for the pressure gauge at an end opposite the connection nozzle, which is preferably designed as a cylindrical or oval recess. The pressure gauge is preferably held without gaps by means of the receptacle on the connecting part, with the pressure gauge preferably resting fully within the cylindrical recess with its surface areas inserted within the receptacle on the connecting part. This ensures a tilt-free guidance between the surface areas of the connecting part and the pressure gauge. Preferably, in one embodiment of the invention, the receptacle for the pressure gauge is designed as a cylindrical recess, which allows the pressure gauge to be moved, in particular rotated, within the receptacle without requiring significant force.An alternative design provides that the receptacle for the manometer part is formed as an oval recess, similar to a groove-like depression, within which the manometer part is slidably mounted.
[0020] According to a preferred embodiment, the pressure gauge part has a cylindrical or oval base body with a plug end that is rotatably or slidably received on the connection part, wherein the pressure gauge interface is formed at an end opposite the plug end. The cylindrical or oval base body of the pressure gauge part is preferably almost completely enclosed within the receptacle on the connection part, so that the pressure gauge part adds only a small amount of height to the connection part of the adapter. Thus, the quick-vent adapter according to the invention has a low overall height, which allows it to be used in a space-saving manner as a connecting element between a pressurized component, such as a fitting, and a pressure gauge mounted on it. The plug end of the pressure gauge part is designed to correspond, in particular, to the cylindrical or oval recess on the receptacle of the connection part.In the oval design of the pressure gauge section and recess, the recess has a corresponding oversize in its longitudinal direction, in the direction the pressure gauge section is moved towards the connecting part for adjustment, compared to the insertion end of the pressure gauge section that is received therein. The pressure gauge interface is located at the end opposite the insertion end, which simplifies the connection of the pressure gauge to the pressure gauge section and thus to the quick-release adapter. The connection port and pressure gauge are located on opposite sides of the adapter.
[0021] According to a further development of the invention, the manometer part has an opening extending from the insertion end to the manometer interface, which, depending on the respective position of the manometer part, is fluidly connected to either the pressure channel or the vent channel. By providing only one opening in the manometer part, the fluid-conducting separation of the pressure channel and the vent channel is further simplified. By rotating the manometer part through a predetermined angle, preferably about 90°, or by moving the manometer part along a distance of about 1 cm, a sufficiently large distance is formed within the receptacle on the connection part between the pressure channel, which is aligned with the opening particularly in the first position, and the vent channel, which is aligned with the opening in the second position.Together with the insert end of the pressure gauge section, which is rotatably or slidably mounted in the receptacle on the connecting part, a sufficiently effective seal is achieved. In this case, the opening in the pressure gauge section defines a segment of the pressure channel or the vent channel, depending on the rotational or sliding position of the pressure gauge section.
[0022] In a further development of the invention, the pressure channel, preferably the opening in the manometer section, extends parallel to the longitudinal axis of the connection section and the manometer section. With the parallel alignment of the pressure channel at the connection section, and in particular the opening in the manometer section, to the longitudinal axis of the adapter, a structurally simple pressure transmission is achieved from the connection nozzle, which in a preferred embodiment has a threaded section with an external thread and is received at a pressure connection with a complementary threaded section of a fitting, towards the manometer interface or a manometer on the manometer section. Preferably, the pressure channel from the connection nozzle to the manometer interface has a completely straight alignment without any pressure-reducing deflections at the adapter.In a preferred embodiment, the manometer interface has a threaded section with an internal thread for receiving the manometer to be mounted on it.
[0023] According to a preferred embodiment, the receptacle on the connecting part has a flat base, with the pressure channel on the connecting part opening at the base of the receptacle, and the opening of the pressure channel being surrounded by a sealing element that interacts with the insertion end of the manometer part. By providing a sealing element, which is preferably annular and completely surrounds the opening of the pressure channel in the receptacle, the fluid-tight seal between the receptacle and the insertion end of the manometer part, which is rotatably mounted in the receptacle, is further improved. The sealing element prevents pressure from transferring from the pressure channel towards the vent channel or from escaping into the environment between the contacting surfaces of the receptacle and the insertion end.In one embodiment, the sealing element has a width which, in the intermediate position range of the manometer part, ensures that the opening in the manometer part is completely covered and thus has no fluid-conducting contact with either the pressure channel or the vent channel.
[0024] According to a preferred embodiment of the rapid venting adapter, the pressure channel, preferably the opening, is arranged radially offset from the longitudinal axis of the connection part and the pressure gauge part. By forming the pressure channel and the opening at a distance of approximately 0.5 to 2 cm from the longitudinal axis of the connection part and pressure gauge part, a sufficiently large distance is created between the first and second movement positions, preferably rotational positions, which preferably define end positions on the adapter. In particular, this further hinders the unintentional transfer of the permanently applied pressure in the pressure channel towards the venting channel. Preferably, the opening in the pressure gauge part defines or forms a section of the pressure channel in the first rotational position and a section of the venting channel in the second rotational position.
[0025] Preferably, the vent channel on the connection part extends radially to the longitudinal axis. In the second position of movement, the vent channel forms a fluid-conducting connection between the pressure gauge interface and the environment surrounding the quick-vent adapter. By radially directing the pressure medium out of the adapter in the venting position, a targeted and controlled venting of the pressure medium in a predetermined direction is achieved at the adapter. Furthermore, due to the reliable and, above all, permanent fluid-conducting separation between the pressure channel and the vent channel, in conjunction with the comparatively small pressure chamber present at the adapter, a significantly reduced amount of pressure medium flows from the outlet of the vent channel into the environment during the venting process compared to known test fittings.The potential risk to a user from the escaping pressure medium is therefore negligible.
[0026] A further development of the quick-vent adapter provides that a locking element is arranged at the insertion end, wherein the receptacle has a radial undercut that interacts with the locking element, which is designed to lock the pressure gauge part axially within the receptacle on the connection part. With the aid of the locking element, which in a preferred embodiment is designed as an elastically deformable retaining ring, the pressure gauge part, which is rotatably or slidably held in the receptacle, can be easily fixed within the receptacle on the connection part without, however, impeding the movement, in particular the rotation or sliding of the pressure gauge part in the receptacle on the connection part.The locking element interacts with an undercut on the circumferential surface of the insertion end, preferably designed as an annular groove. The groove on the pressure gauge part has a depth that corresponds at least to the width of the retaining ring in the radial direction. The undercut in the receptacle is preferably designed as a circumferential groove and is approximately at the same height as the annular groove on the insertion end. Preferably, in the locked position of the pressure gauge part in the receptacle, the locking element exerts a clamping force between a similarly flat end face on the insertion end of the pressure gauge part and the sealing element located at the base of the receptacle and extending around the pressure channel opening, which projects a predetermined minimum distance beyond the base of the receptacle. This further increases the sealing effect of the pressure gauge part against the receptacle on the connection part.
[0027] According to a preferred embodiment of the rapid venting adapter, stops projecting into the adjustment range of the pressure gauge section are formed on the connection part and the pressure gauge section to define the first and second positions of movement, preferably rotational positions, of the pressure gauge section. This defines fixed end positions for the pressure gauge section in the first and second positions and ensures precise alignment of the opening on the pressure gauge section with the pressure channel or vent channel on the connection part for implementing the pressure transmission or venting function. Preferably, the pressure gauge section has a radially outwardly projecting extension along a region of its outer circumference, which engages in at least one recess formed in the connection part.By means of the component areas on the manometer part and the connection part that can be brought into contact with each other, the stop function is implemented in a structurally simple way in both movement positions, preferably the first and second rotational position of the manometer part to the connection part, in which the opening on the manometer part in the respective rotational position then preferably runs in alignment with the pressure channel or vent channel.
[0028] In a further development of the quick-vent adapter, the pressure gauge section features a handle for moving it between the first and second positions. Using this handle, which is located directly on the pressure gauge section, it is easy to move the section back and forth between the first and second rotary or sliding positions on the connecting part. The handle can, for example, be designed as an actuating lever located on the radially outwardly projecting extension of the pressure gauge section. In an alternative embodiment, the quick-vent adapter is configured to be moved back and forth between the first and second positions by applying an adjusting force to the pressure gauge mounted on the pressure gauge section. Adjusting the quick-vent adapter between the first and second positions via the pressure gauge attached to it further simplifies operation.However, it must be ensured that measures are taken to prevent an unintentional loosening of a manometer mounted at the manometer interface.
[0029] According to a second aspect, the invention relates to a rapid venting adapter for testing the functionality of a pressure gauge, comprising a connection part with a connection nozzle for fluid-conducting connection to a pressurized component, wherein the connection nozzle has a pressure inlet and a pressure gauge part with a pressure gauge arranged on the connection part and movable relative to the connection part. The invention also solves the problem underlying this rapid venting adapter with the features according to claim 14.The quick-release adapter with a manometer arranged directly on its manometer part also features a simple adjustment movement of the manometer part on the connection part, achieved by means of which the manometer part is inclined in a plane at an angle of greater than 70°, in particular perpendicular to the direction of flow, and by means of which the functional testing of the manometer mounted on the quick-release adapter is possible in a simple and reliable way.
[0030] According to a preferred embodiment of the rapid venting adapter as described in the second aspect, the pressure gauge is integrally formed with the pressure gauge part, or the pressure gauge or the pressure gauge part forms part of the other, and / or the adapter is designed according to at least one feature of the preferred embodiments described above as described in the first aspect. The integral design, or the one-piece construction between the pressure gauge part and the pressure gauge, results in a structurally simple design without the need for an additional interface between the pressure gauge part and the pressure gauge. This prevents the pressure gauge from unintentionally detaching from the pressure gauge part during operation of the adapter, particularly when an adjusting force is applied to the pressure gauge.Preferably, the quick-vent adapter according to the second aspect is designed according to one of the preferred embodiments of the quick-vent adapter according to the first aspect described above, provided that these do not contradict each other, for example, with regard to the pressure gauge interface provided on the quick-vent adapter according to the first aspect. Preferably, the pressure gauge part has a cylindrical or oval base body with a plug end that is rotatably or slidably received on the connection part, with the pressure gauge being arranged at an end opposite the plug end. Furthermore, the pressure gauge part has an opening extending from the plug end to the pressure gauge, which is fluidly connected to the pressure channel or the vent channel, depending on the respective position of movement of the pressure gauge part.In this case, the opening extending from the insertion end on the manometer part to the manometer defines a section of the pressure channel or the vent channel, depending on the position of movement of the manometer part relative to the connection part.
[0031] In a further aspect, the invention relates to a fitting, in particular a fire extinguishing system valve, with a housing and at least one pressure chamber within the housing, wherein the housing has at least one pressure port for a manometer connected fluid-conducting to the pressure chamber, and a manometer connected fluid-conducting to the housing via its pressure port.
[0032] The invention also solves the problem underlying the quick-vent adapter by arranging a quick-vent adapter according to one of the preferred embodiments described above in a connection area between the pressure port and the pressure gauge. Such a quick-vent adapter according to the invention is used as a kind of intermediate component between the pressure port on the fitting and the pressure gauge to be mounted on the fitting. With the inventive design of the quick-vent adapter, this intermediate component adds only minimal bulk to the pressure port of the fitting, thus significantly reducing the installation space required for accommodating a quick-vent adapter according to the invention.Furthermore, a venting function can be implemented by means of the manometer section rotatably mounted on the connection part of the quick-vent adapter according to the invention. During venting, a comparatively small amount of the pressure medium contained in the quick-vent adapter escapes, thus preventing any risk to a user operating the quick-vent adapter. In one embodiment, the manometer is attached to the manometer section via a manometer interface. In an alternative embodiment, the manometer and the manometer section are formed as a single unit on the quick-vent adapter.
[0033] According to a further aspect, the invention relates to a method for venting a manometer arranged on a fitting using a quick-venting adapter, in particular a quick-venting adapter according to one of the preferred embodiments described above.
[0034] The method according to the invention also solves the problem described at the outset with the following steps: providing orMounting a pressure gauge on a pressurized fitting using a quick-release adapter as an intermediate component between the fitting and the pressure gauge, establishing a fluid-conducting connection between the fitting and the pressure gauge in a first movement position of the pressure gauge relative to the fitting, and moving the pressure gauge, in particular rotating or displacing the pressure gauge (106), in a plane inclined at an angle greater than 70°, preferably perpendicular, to an inflow direction defined by a pressure channel on the quick-release adapter (10) from the first movement position defining a pressure transmission position to a second movement position defining a venting position, in which the pressure transmission, in particular in a pressure channel formed on the adapter, is interrupted in the direction of the pressure gauge and the venting, in particular by means of a venting channel formed on the adapter, is released into the environment.
[0035] The invention is based on the finding that, compared to the prior art, the inventive method steps simplify the venting of a pressure gauge mounted on a fitting and, in particular, the testing of the pressure gauge's functionality in the vented state. Instead of accidentally coming into contact with the pressure medium exiting the vent channel during venting with known venting adapters, or the uncontrolled escape of the pressure medium when establishing a pressure-transmitting connection between the pressure gauge part and the pressure port on the connection part, the inventive method steps enable targeted and controlled venting.In particular, when the manometer section is moved in a plane at an angle greater than 70°, preferably perpendicular, to a flow direction defined by a pressure channel on the rapid venting adapter, from the first rotary or sliding position to the second rotary or sliding position, the fluid connection between the pressure port and the manometer is immediately disconnected. Specifically, only after the fluid connection between the pressure port and the manometer has been disconnected is the venting channel opened, thus re-establishing the fluid connection between the manometer and the environment. This ensures that a comparatively small amount of the pressurized medium is released in a controlled manner at the rapid venting adapter according to the invention during venting, thereby preventing any potential hazard to a user implementing the method.In a preferred further development, in order to enable the pressure measurement to be repeated using the manometer, the manometer, in particular a manometer part receiving the manometer, is moved from the second movement position back to the first movement position.
[0036] The preferred embodiments and further developments described for the rapid venting adapter according to the invention are also preferred embodiments of the fitting and the method according to the invention for venting a pressure gauge arranged on a fitting. Preferred embodiments and further developments described for the fitting and the method, which relate to the rapid venting adapter, are also preferred embodiments of the present rapid venting adapter.

[0045] Fig. 1 shows a quick-vent adapter 10, by means of which the functionality of a pressure gauge 106 (Fig. 7) arranged on a fitting 100 can be tested. The quick-vent adapter 10 comprises a connection part 12, which has a connection nozzle 14 for fluid-conducting connection to a pressure port 104, 104' of the pressurized component, in particular the fitting 100. The quick-vent adapter 10 further comprises a pressure gauge part 16 arranged on the connection part 12 and movable relative to it, which has a pressure gauge interface 18 for fluid-conducting coupling with the pressure gauge 106.
[0046] The rapid venting adapter 10, see Fig. 5, has a pressure inlet 20 at the connection port 14 and a pressure channel 22 extending from the pressure inlet 20 towards the pressure gauge interface 18. During normal operation, pressure is transmitted via the pressure channel 22 to the pressure gauge 106 located at the pressure gauge interface 18. The rapid venting adapter 10, see Fig. 3, also includes a venting channel 24 extending from the pressure gauge interface 18 to the environment, by means of which the pressure gauge 106 can be vented at predetermined intervals and its functionality checked.
[0047] According to the present embodiment, the pressure gauge part 16 is rotatably mounted on the connection part 12. The pressure gauge part 16 is specifically designed to move back and forth between a first rotary position S1, shown in Fig. 2, which releases the pressure channel 22, and a second rotary position S2, shown in Fig. 3, which releases the vent channel 24. In a preferred embodiment, the pressure gauge part 16, while moving between the first rotary position S1, which defines a pressure transmission position, and the second rotary position S2, which defines a venting position, is designed to release either exclusively the pressure channel 22 or exclusively the vent channel 24.
[0048] As can be seen in Fig. 4, the manometer section, during movement between the first and second rotary positions S1 and S2, is further configured to assume an intermediate position range Sz in which the pressure channel 22 and the vent channel 24 are each closed. The intermediate position range Sz is preferably defined, starting from the first rotary position S1, within an angular range β1 of approximately 35° to 40°, particularly at approximately 37.6°, in which the vent channel 24 is completely closed. The intermediate rotary position range Sz is preferably defined, starting from the second rotary position S2, within an angular range β2 of approximately 50° to 55°, particularly at approximately 52.4°, in which the pressure channel 22 is completely closed.
[0049] The sectional views in Figures 5a and 5b show the quick-vent adapter 10 in its first position of movement, in particular its rotational position, S1. As can be seen in the figures, the connecting part 12 has a receptacle 28 for the pressure gauge part 16 at an end 26 opposite the connecting nozzle 14, in which the pressure gauge part 16 can be rotated. The receptacle 28 is designed as a cylindrical recess, and the pressure gauge part 16 has a cylindrical base body 30. The receptacle 28 and the base body 30 have complementary inner and outer contours, respectively, which ensures the rotation of the pressure gauge part 16 in the receptacle 28. A insertion end 32 is provided on the pressure gauge part 16, in particular on the base body 30, by means of which the pressure gauge part 16 is almost completely received in the receptacle 28. The manometer interface 18 is formed at the end 34 opposite the insertion end 32.In an embodiment not shown in detail, the manometer part 16 and the manometer 106 arranged thereon (Fig. 7) are formed in one piece, in particular without an intermediate manometer interface.
[0050] As can also be seen from Fig. 5a, the manometer part 16 has an opening 38 at its insertion end 32, extending in particular from a flat end face 36 to the manometer interface 18. In the rotational position S1 of the manometer part 16, the opening 38 is fluid-conductingly connected to the pressure channel 22 or the vent channel 24. The opening 38 thus defines a section of the pressure channel 22 or the vent channel 24 in the respective rotational positions S1 and S2.
[0051] Figure 5b shows that the vent channel 24 has no fluid-conducting connection to the manometer interface 18 in the movement position S1. In movement position S1, one end of the vent channel 24 facing the manometer part terminates at the insertion end 32 in the region of the end face 36, where the opening 38 extending towards the manometer interface 18 opens and which forms a sealing surface 39 for the vent channel 24 in movement position S1 and for the pressure channel 22 in movement position S2.
[0052] The sectional views in Figs. 6a and 6b show the quick-vent adapter 10 in its second position of movement, in particular in the rotation position S2 and thus in the venting position, in which a fluid-conducting connection is formed between the manometer interface 18 via the opening 38 in the manometer part to the vent channel 24. Fig. 6b illustrates that in the movement position S2 there is no fluid-conducting connection between the manometer interface 18 and the pressure channel 22.
[0053] The sealing surface 39 formed on the end face 36 is exposed to the flow direction X defined by the pressure channel 22 at the connection part 12 in the movement position S2. According to the invention, the manometer part 16 is supported on the connection part 12 opposite to the flow direction X and is inclined in a plane at an angle greater than 70°, in the embodiment shown here perpendicular to the flow direction X, and rotatably mounted on the connection part 12 in order to be moved from the movement position S1 to the movement position S2.
[0054] As can be seen further in Figs. 5a to 6b, the receptacle 28 has a flat base 40, at which the pressure channel 22 has an opening 42. In the area of the opening 42, a recess 44 is formed for a sealing element 46 surrounding the pressure channel 22.
[0055] In the present embodiment, the sealing element 46 is fixedly arranged in the recess 44 at the base 40 of the receptacle 28 and its end face 36 is in sealing contact with the insertion end 32 of the manometer part 16. This prevents the pressure medium from flowing from the pressure channel 22 towards the vent channel 24 and ensures that when the manometer part 16 is moved, either only the pressure channel 22 or the vent channel 24 is opened.
[0056] As shown in Figs. 5a and 6b, the pressure channel 22, as well as the opening 38, runs parallel to a longitudinal axis L of the connection part 12 and the manometer part 16. The pressure channel 22 and preferably also the opening 38 are arranged radially offset to the longitudinal axis L and thus at a distance from the longitudinal axis L of the connection part 12 and the manometer part 16.
[0057] In the embodiment shown in Figs. 5b and 6a, the vent channel 24 extends radially to the longitudinal axis L. The vent channel 24 has an outlet 51 on the outer circumferential surface 48 of the connecting part 12, which in this case is designed as a hexagon 50 and thus as a tool attachment, for the pressure medium flowing out into the environment during venting. A locking element 52 is arranged at the insertion end 32 of the manometer part 16, and the receptacle 28 on the connecting part 12 has a radial undercut 54 near its base 40. The locking element 52 interacts with the undercut 54 and is designed to lock the manometer part 16 axially within the receptacle 28. Furthermore, the connecting piece 14 has a threaded section 66 designed as an external thread and the manometer interface 18 has a threaded section 66' designed as an internal thread.In one possible embodiment, the base body 30 has an annular groove 68, within which a ring element 70 is arranged for guiding the base body 30 without tilting within the receptacle 28 on the connecting part 12, making it possible to move, in particular to rotate, the manometer part 16 to the connecting part with little effort.
[0058] In the embodiment shown in Figs. 5a-6b, the locking element 52 is designed as a retaining ring 56 and the radial undercut 54 as a fully circumferential groove 58. Preferably, a holding force in the axial direction is generated on the receptacle 28 by means of the locking element 52 and the undercut 54, by means of which a compressive force FD simultaneously acts on the sealing element 46 arranged in the recess 44 at the base 40 of the receptacle 28 to generate the sealing effect with the interacting insertion end 32 of the manometer part 16.
[0059] As can be further seen from Figures 1 to 4, the connecting part 12 and the manometer part 16 have stops 60, 60' projecting towards each other in the rotational path of the manometer part 16. The rotational movement B is limited by means of the stops 60, 60', and the respective first and second rotational positions S1, S2 are defined. The stops 60 on the manometer part 12 are formed by means of a material recess 62, and the stops 60' on the manometer part 16 are formed by means of a projection 64 extending radially outwards from its base body 30.
[0060] Figures 7a and 7b show a pressurized fitting 100, in particular a fire extinguishing system valve 100', which has a housing 102 and at least one pressure chamber (not shown in detail) within the housing. The housing 102 has at least one, in this case two, connections 104, 104' fluid-conducting to the pressure chamber for a manometer 106 mounted thereon. Furthermore, the fitting 100 has a manometer 106 fluid-conducting to the housing 102 via its connections 104, 104'. In the connection area between the connections 104, 104' and each of the manometers 106 fluid-conducting to them, a quick-venting adapter 10 according to the invention is arranged as a kind of intermediate component 108. As shown in Figures 7a and 7b, the connection between the connections 104, 104' and the manometer 106 is fluid-conducting.Figure 7b illustrates that the upper manometer 106 is in the pressure transmission position by means of the adapter 10, and the lower manometer 106 is moved into the venting position by turning it by an angle of rotation a of about 90° and is thus depressurized.
[0061] In an embodiment not shown in detail, the rapid venting adapter 10 is still provided as an intermediate component in the connection area between a connection 104, 104' and a pressure gauge 106 connected to it in a fluid-conducting manner, whereas the pressure gauge 106 is then not coupled to a pressure gauge interface 18 as described in more detail in the previous figures, but the pressure gauge part 16 is formed integrally on or as a single unit with the pressure gauge 106. The pressure gauge part 16, which is movable in the connection part 12 of the rapid venting adapter 10, is then, in particular, part of the pressure gauge 106.
[0062] Fig. 8 shows a sectional view of a second embodiment of a rapid venting adapter 10' according to the invention, which is fundamentally similar to the rapid venting adapter 10 shown in the previous figures. The rapid venting adapter 10' also has a connection part 12' with a connection nozzle 14 for fluid-conducting connection to a pressurized component, such as a fitting 100. The connection nozzle 14 includes a pressure inlet 20. A manometer part 16', movable relative to the connection part 12, is arranged on the connection part 12, with a manometer interface 18 for fluid-conducting coupling to a manometer 106. In an embodiment not shown in detail, a manometer 106 is integrally formed with the manometer part 16' instead of the manometer interface 18.
[0063] The adapter 10' also has at least one pressure channel 22 extending from the pressure inlet 20 towards the manometer interface 18 and a vent channel 24 extending from the manometer interface 18 to the environment. The manometer part 16 is designed to move back and forth between a first movement position S1, shown in particular in Fig. 8, which releases the pressure channel 22, and a second movement position S2, which releases the vent channel 24.
[0064] The manometer part 16 also has a closing surface 39 on its end face 36 at the insertion end 32, which closes the pressure channel 22. In the movement position S2, this closing surface is exposed to the flow direction X defined by the pressure channel 22 at the connection part. In the second embodiment, the manometer part 16 is supported on the connection part 12 opposite to the flow direction X and is movably mounted on the connection part 12 at an angle greater than 70°, preferably perpendicular, to the flow direction X. In the present embodiment, the manometer part 16 is slidably mounted on the connection part 12, in particular on its receptacle 28', which is designed as an oval recess.
[0065] In the present case, the insertion end 32 of the manometer part 16, which is received in the oval receptacle 28' on the connecting part 12, has a base body 30' that is oval in shape corresponding to the receptacle 28'. The manometer part 16 of the embodiment shown in Fig. 8 also has an opening 38 extending from the insertion end 32 to the manometer interface 18. In the movement position S1 shown in Fig. 8, the opening is fluid-conducting and connected to the pressure channel 22. In particular, by moving the manometer part 16 within the receptacle 28', the fluid-conducting connection to the pressure channel 22 is interrupted and the fluid-conducting connection between the opening 38 and the vent channel 24 is established.
[0066] Furthermore, as shown in Fig. 8, a locking element 52 is arranged at the insertion end 32 of the pressure gauge part 16, and the receptacle 28 on the connection part 12 has a radial undercut 54 near its base 40. The locking element 52 interacts with the undercut 54 and is designed to lock the pressure gauge part 16 axially within the receptacle 28. The connection nozzle 14 also has a threaded section 66 designed as an external thread, and the pressure gauge interface 18 has a threaded section 66' designed as an internal thread. In one possible embodiment, the base body 30 has an annular groove 68 within which a ring element 70 is arranged to guide the base body 30 without tilting within the receptacle 28 on the connection part 12, thus enabling the pressure gauge part 16 to be moved, in particular rotated, relative to the connection part with minimal effort.
[0067] The locking element 52 is designed as a retaining ring 56 and the radial undercut 54 as a fully circumferential groove 58. Preferably, a holding force in the axial direction is generated on the receptacle 28 by means of the locking element 52 and the undercut 54, by means of which a compressive force FD simultaneously acts on the sealing element 46 arranged in the recess 44 at the base 40 of the receptacle 28 to generate the sealing effect with the interacting insertion end 32 of the manometer part 16.
[0068] Figure 9 shows a method 200 according to the invention for venting a pressure gauge 106 arranged on a fitting 100 using a quick-venting adapter 10. The method 200 comprises at least a first step 202, relating to providing or mounting a pressure gauge 106 on a pressurized fitting 100 and establishing a fluid-conducting connection between the fitting 100 and the pressure gauge 106 in a first rotational position S1 of the pressure gauge 106 relative to the fitting 100.Method 200 further comprises a second step 204, relating to moving the manometer 106, in particular rotating or displacing the manometer (106), inclined in a plane at an angle greater than 70°, preferably perpendicular, to an inflow direction (X) defined by a pressure channel on the quick-vent adapter (10) from the first movement position S1 defining a pressure transmission position to a second movement position S2 defining a venting position, in which the pressure transmission in the direction of the manometer 106 is interrupted and venting to the environment is released.
[0069] Preferably, the manometer part is rotated or moved in the plane specifically defined for the direction of flow X in order to transfer it from the movement position S1 to the movement position S2.
