Description

Technical Field

[0001] The present disclosure relates to a valve assembly, such as a gas valve assembly. More particularly, the present disclosure relates to a valve assembly for a combustion appliance. Background Art

[0002] A combustion appliance typically includes a burner chamber and one or more conduits in fluid communication with the burner chamber. The one or more conduits may include a conduit for air and a conduit for fuel. The fuel may be a combustible gas. One or more valves may act on the conduit for fuel to control the flow of fuel to the burner chamber. Similarly, one or more valves may act on the conduit for air to control the flow of air into the burner chamber.

[0003] A valve, such as a gas valve, may include more than one valve member or more than one poppet. That is, there may be more than one movable member or more than one poppet acting on the flow of air or fuel through the valve. A common actuator may be present for selectively moving all valve members between closed and open positions. Alternatively, separate actuators may be present, each coupled to a single valve member.

[0004] Valves can utilize multiple valve components or poppet valves connected in series and / or in parallel. Arranging multiple valve components in parallel increases the cross-sectional area of ​​the valve. This increased cross-sectional area increases the maximum air or fuel flow through the valve. In other words, multiple parallel valve components increase the maximum flow rate.

[0005] A valve with several valve members may involve multiple flow paths between the valve's inlet port and the valve's outlet port. These flow paths may interfere with each other. A first flow path may, for example, intersect with a second flow path. Eddies may also exist in the first flow path, and these eddies may alter the flow along the second flow path.

[0006] The valve may include one or more ports for pressure sensors. Fluid flow along one or more fluid paths may then generate eddies at or near the ports of the pressure sensors. Consequently, any readings obtained from the sensors at or near the ports may be misleading and / or incorrect.

[0007] A valve assembly having several valve members appears to be common in oxygen supply systems for aircraft. Patent US4148311A was granted on April 10, 1979. The application for this patent was filed on May 18, 1977. US4148311A relates to a gas mixing device.

[0008] US Patent No. 4,148,311A relates to a common conduit that is divided into a first conduit and a second conduit. A first toggle valve acts on the first conduit, and a second toggle valve acts on the second conduit. When the fluid exits the valves, the two conduits merge again into a common conduit. The common conduit is used to supply oxygen to the mask. In US Patent No. 4,148,311A, the flow paths along the first conduit and along the second conduit are largely separate, resulting in minimal flow interference.

[0009] Arrangements with multiple pipes also appear to be common in the field of semiconductor manufacturing. Patent application US2001 / 0004903A1 was filed on December 13, 2000. The application was published on June 28, 2001. US2001 / 0004903A1 relates to a parallel split-flow fluid supply device.

[0010] US2001 / 0004903A1 discloses a fluid supply assembly comprising a pressure regulator having an upstream side and a downstream side. Multiple pipelines are arranged downstream of the pressure regulator, such that a single pipeline from the regulator branches into parallel flow channels. Each flow channel is associated with a flow control valve acting on the channel. Multiple mass flow controllers are used to control the flow through the assembly. The flow paths in US2001 / 0004903A1 follow the flow channels. The flow paths are largely separated, resulting in minimal interference between the flow channels.

[0011] In the field of combustion appliances, patent US6457444B1 was granted on October 1, 2002. Application 09 / 933,394 of US6457444B1 was filed on August 20, 2001. US6457444B1 relates to a multi-valve system for an internal combustion engine.

[0012] US6457444B Figure 1 A cylinder head having multiple apertures is shown. Intake and exhaust valves are associated with the apertures in the cylinder head. The intake and exhaust valves are in fluid communication with the cylinders. That is, these valves are each connected to a single cylinder.

[0013] The present disclosure introduces a valve for a combustion appliance. The valve of the present disclosure minimizes interference between flow paths within the valve. Summary of the Invention

[0014] The present disclosure relates to a valve assembly having two pairs of valve components. The valve assembly also has two pairs of valve seats. A first pair of valve components is configured to mate with a first pair of valve seats. A second pair of valve components is configured to mate with a second pair of valve seats. A flow deflector and / or baffle assembly is disposed within the valve assembly. The flow deflector and / or baffle assembly creates at least two separate flow paths through the valve assembly. The first flow path resides on a first side of the valve assembly. The second flow path resides on a second side of the valve assembly, the second side being opposite the first side.

[0015] Due to the flow deflector and / or the baffle assembly, the flow paths within the valve assembly do not intersect with each other. Because the flow paths do not intersect, there will be fewer eddies and less turbulence within the valve assembly. Eddies and turbulence can negatively impact the efficiency of fluid flow through the valve. Therefore, a valve assembly with a flow deflector and / or baffle assembly offers benefits in terms of efficient flow.

[0016] It is contemplated that the flow diverter is a central flow diverter. The central flow diverter is located in the center of the valve assembly. The central flow diverter cooperates with one of the valve members of the first pair of valve members to redirect the flow path through the valve assembly. The central flow diverter is ideally shaped to facilitate redirection of the flow path.

[0017] It is contemplated that the valve assembly includes an inlet flow diverter. The inlet flow diverter is disposed at or near the inlet of the valve assembly. The inlet flow diverter cooperates with the first pair of valve seats to separate two flow paths through the valve assembly. The inlet flow diverter is desirably shaped to facilitate separation of the flow paths. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] The first valve stem 6a is advantageously coupled to a first actuator, such as a first stepper motor, a first hydraulic actuator, or a first solenoid actuator. The first actuator is configured to selectively move the first valve stem 6a and the first valve member 4a between a closed position and an open position.

As another example, the valve assembly 1 may include twelve or more valve members. Each valve member is advantageously associated with a valve seat of the valve assembly 1.

[0050] The first valve member 4a and the third valve member 4c of the valve assembly 1 are arranged in parallel. If both the first and third valve members 4a, 4c are closed, the fluid path between the inlet port 2 and the outlet port 3 is closed. As long as at least one of the first valve member 4a and the third valve member 4c of the valve assembly 1 is in its open position, the fluid path remains open. The parallel valve members 4a, 4c increase the cross-section of the valve assembly 1.

[0051] In one embodiment, the first valve member 4a is mechanically coupled to the third valve member 4c. The first valve member 4a and the third valve member 4c are preferably rigidly connected. In a specific embodiment, the first valve member 4a and the third valve member 4c are even formed as a single component. When the third valve member 4c is closed, the first valve member 4a is closed, and vice versa. Similarly, when the third valve member 4c is opened, the first valve member 4a is opened, and vice versa.

[0052] The second valve member 4b and the fourth valve member 4d of the valve assembly 1 are arranged in parallel. If both the second and fourth valve members 4b, 4d are closed, the fluid path between the inlet port 2 and the outlet port 3 is closed. As long as at least one of the second valve member 4b and the fourth valve member 4d of the valve assembly 1 is in its open position, the fluid path remains open. The parallel valve members 4b, 4d increase the cross-section of the valve assembly 1.

[0053] In one embodiment, the second valve member 4b is mechanically coupled to the fourth valve member 4d. The second valve member 4b and the fourth valve member 4d are preferably rigidly connected. In a specific embodiment, the second valve member 4b and the fourth valve member 4d even form a single component. When the fourth valve member 4d is closed, the second valve member 4b is closed, and vice versa. Similarly, when the fourth valve member 4d is opened, the second valve member 4b is opened, and vice versa.

[0054] With the first valve member 4a and the third valve member 4c rigidly coupled, the first valve member 4a and the second valve member 4b are arranged in series. If at least one of the first and second valve members 4a, 4b is closed, the fluid path between the inlet port 2 and the outlet port 3 will be closed. As long as the first valve member 4a and the second valve member 4b of the valve assembly 1 are in their open positions, the fluid path will remain open.

[0055] With the second valve member 4b and the fourth valve member 4d rigidly coupled, the third valve member 4c and the fourth valve member 4d of the valve assembly 1 are arranged in series. If at least one of the third and fourth valve members 4c, 4d is closed, the fluid path between the inlet port 2 and the outlet port 3 will be closed. As long as the third valve member 4c and the fourth valve member 4d of the valve assembly 1 are in their open positions, the fluid path will remain open.

[0056] Now go to Figure 2 , showing two flow paths 7a, 7b through the valve assembly 1. The first flow path 7a is preferably different from the second flow path 7b. The valve assembly 1 includes a common housing having a first side 8a and a second side 8b. The first side 8a of the common housing of the valve assembly 1 is different from the second side 8b of the common housing of the valve assembly 1. The first side 8a of the common housing of the valve assembly 1 is preferably arranged opposite the second side 8b of the common housing of the valve assembly 1.

[0057] The first connector 9a mechanically connects the first valve member or first poppet valve 4a and the third valve member or third poppet valve 4c. The second connector 9b mechanically connects the second valve member or second poppet valve 4b and the fourth valve member or fourth poppet valve 4d. The first connector 9a is advantageously different from the second connector 9b.

[0058] According to one aspect of the present disclosure, the first connector 9a includes a first cylindrical portion. The first cylindrical portion surrounds a portion of the first valve stem 6a. As a non-limiting example, the first cylindrical portion can be press-fitted or shrink-fitted to the first valve stem 6a. More specifically, the first cylindrical portion can be press-fitted or shrink-fitted to a portion of the first valve stem 6a. According to a related aspect of the present disclosure, the second connector 9b includes a second cylindrical portion. The second cylindrical portion surrounds a portion of the second valve stem 6b. As a non-limiting example, the second cylindrical portion can be press-fitted or shrink-fitted to the second valve stem 6b. More specifically, the second cylindrical portion can be press-fitted or shrink-fitted to a portion of the second valve stem 6b.

[0059] The valve assembly 1 includes a pair of upstream valve seats 5a, 5c. The pair of upstream valve seats 5a, 5c is located closer to the inlet port 2 than to the outlet port 3. The pair of upstream valve seats 5a, 5c includes a first valve seat 5a and a third valve seat 5c. The valve assembly 1 includes a pair of downstream valve seats 5b, 5d. The pair of downstream valve seats 5b, 5d is located closer to the outlet port 3 than to the inlet port 2. The pair of downstream valve seats 5b, 5d includes a second valve seat 5b and a fourth valve seat 5d.

[0060] The valve assembly 1 includes a pair of upstream valve components 4a, 4c. The upstream valve components 4a, 4c are positioned closer to the inlet port 2 than to the outlet port 3. The upstream valve components 4a, 4c include a first valve component or first poppet valve 4a and a third valve component or third poppet valve 4c. The valve assembly 1 includes a pair of downstream valve components 4b, 4d. The downstream valve components 4b, 4d are positioned closer to the outlet port 3 than to the inlet port 2. The downstream valve components 4b, 4d include a second valve component or second poppet valve 4b and a fourth valve component or fourth poppet valve 4d.

[0061] A fluid, such as a gaseous fluid, enters the valve assembly via inlet port 2. The flow through valve assembly 1 then branches into two flow paths 7a and 7b. The first flow path 7a reaches the first valve seat 5a. After flowing through the third valve seat 5a, the first flow path 7a bypasses the first valve member or first poppet valve 4a. The first flow path 7a then changes from the first side 8a of the common housing of the valve assembly 1 to the second side 8b of the common housing of the valve assembly 1. After changing sides, the flow path 7a reaches and flows through the fourth valve seat 5d. The first flow path 7a then flows between the second valve member or second poppet valve 4b and the fourth valve member or fourth poppet valve 4d. In this way, the first flow path 7a can bypass the second connector 9b. As a non-limiting example, the first flow path 7a can bypass the second connector 9b from the side. The first flow path 7a ultimately reaches the outlet port 3.

[0062] The second flow path 7b reaches the third valve seat 5c. After flowing through the third valve seat 5c, the second flow path 7b bypasses the third valve member or first poppet valve 4c. The second flow path 7b then changes from the second side 8b of the common housing of the valve assembly 1 to the first side 8a of the common housing of the valve assembly 1. After changing sides, the second flow path 7b reaches and flows through the second valve seat 5b. The second flow path 7b continues between the second valve seat 5b and the second valve member or second poppet valve 4b. The second flow path 7b ultimately reaches the outlet port 3.

[0063] When flow paths 7a, 7b change sides 8a, 8b, first flow path 7a intersects second flow path 7b. When flow paths 7a, 7b change sides 8a, 8b, first flow path 7a may also partially intersect second flow path 7b. Partial intersect means that a first portion of first flow path 7a intersects a first portion of second flow path 7b. Partial intersect also means that a second portion of first flow path 7a does not intersect a second portion of second flow path 7b. Figure 2 The first flow path 7a is shown intersecting the second flow path 7b between the first connector 9a and the downstream valve seats 5b, 5d.

[0064] The intersection of the flow paths 7a, 7b causes eddies and turbulence in the region where the first flow path 7a intersects the second flow path 7b. The eddies and turbulence have a negative impact on the amount of flow between the inlet port 2 and the outlet port 3 of the valve assembly 1, i.e., fluid delivery through the valve assembly 1 may become less efficient.

[0065] Now refer to Figure 3, shows a valve assembly 1 having a baffle assembly 10. The baffle assembly 10 divides the valve assembly 1 into a first side 11a and a second side 11b. The first side 11a of the valve assembly 1 points toward the first side 8a of the common housing. In one embodiment, the first side 11a of the valve assembly 1 is positioned adjacent to the first side 8a of the common housing. The second side 11b of the valve assembly 1 points toward the second side 8b of the common housing. In one embodiment, the second side 11b of the valve assembly 1 is positioned adjacent to the second side 8b of the common housing.

[0066] The first side 11a of the valve assembly 1 is different from the second side 11b of the valve assembly 1. The first side 11a of the valve assembly 1 and the second side 11b of the valve assembly 1 are disposed on opposite sides of the baffle assembly 10.

[0067] According to one aspect of the present disclosure, the baffle assembly 10 includes one or more flow deflectors. In one particular embodiment, the baffle assembly 10 is a flow deflector. In another particular embodiment, the baffle assembly 10 is a baffle.

[0068] Figure 3 A first protrusion 12a is shown. The first protrusion 12a protrudes from the first side 8a of the common housing of the valve assembly 1. The first protrusion 12a is preferably positioned downstream of the first valve member or first poppet valve 4a. The first protrusion 12a is preferably positioned upstream of the second valve member or second poppet valve 4b. Similarly, the first protrusion 12a is preferably positioned downstream of the first connector 9a. The first protrusion 12a is preferably positioned upstream of the second connector 9b. Advantageously, the first protrusion 12a is mechanically connected to the first valve seat 5a.

[0069] Figure 3 A second protrusion 12b is shown. The second protrusion 12b protrudes from the second side 8b of the common housing of the valve assembly 1. The second protrusion 12b is preferably positioned downstream of the third valve member or third poppet 4c. The second protrusion 12b is preferably positioned upstream of the fourth valve member or fourth poppet 4d. Similarly, the second protrusion 12b is preferably positioned downstream of the first connector 9a. The second protrusion 12b is preferably positioned upstream of the second connector 9b. Advantageously, the second protrusion 12b is mechanically connected to the third valve seat 5c.

[0070] The first protrusion 12a is different from the second protrusion 12b.

[0071] A fluid, such as a gaseous fluid, enters the valve assembly via the inlet port 2. The flow through the valve assembly 1 then branches into a third flow path 7c and a fourth flow path 7d. The third flow path 7c reaches the first valve seat 5a. After flowing through the first valve seat 5a, the third flow path 7c bypasses the first protrusion 12a. The third flow path 7c flows through the channel formed by the first protrusion 12a and the baffle assembly 10. In this way, the baffle assembly 10 directs the third flow path 7c to the second valve seat 5b. The third flow path 7c then flows through the second valve seat 5b, which is located downstream of the first protrusion 12a. After flowing through the second valve seat 5b, the third flow path 7c reaches the second valve member or second poppet 4b. The third flow path 7c ultimately reaches the outlet port 3.

[0072] The fourth flow path 7d reaches the third valve seat 5c. After flowing through the third valve seat 5c, the fourth flow path 7d bypasses the second protrusion 12b. The fourth flow path 7d flows through the channel formed by the second protrusion 12b and the baffle assembly 10. Thus, the baffle assembly 10 directs the fourth flow path 7d to the fourth valve seat 5d. The fourth flow path 7d then flows through the fourth valve seat 5d, which is positioned downstream of the second protrusion 12b. After flowing through the fourth valve seat 5d, the fourth flow path 7d reaches the fourth valve member or poppet valve 4d. The fourth flow path 7d continues between the second valve member or poppet valve 4b and the fourth valve member or poppet valve 4d. This allows the fourth flow path 7d to bypass the second connector 9b. As a non-limiting example, the fourth flow path 7d can bypass the second connector 9b from the side. The fourth flow path 7d ultimately reaches the outlet port 3.

[0073] The third flow path 7c is different from the fourth flow path 7d.

[0074] Due to the baffle assembly 10, the third flow path 7c does not intersect the fourth flow path 7d. More specifically, as Figure 4 The illustrated third flow path 7c does not intersect the fourth flow path 7d between the first connector 9a and the downstream valve seats 5b, 5d. Between the first valve seat 5a and the second valve member or second poppet 4b, the third flow path 7c resides on the first side 11a. More specifically, the third flow path 7c resides on the first side 11a of the valve assembly 1. Between the third valve seat 5c and the fourth valve member or fourth poppet 4d, the fourth flow path 7d resides on the second side 11b. More specifically, the fourth flow path 7d resides on the second side 11b of the valve assembly 1.

[0075] Because the third flow path 7c does not intersect the fourth flow path 7d, the valve assembly 1 having the flapper assembly 10 experiences less eddy flow. The valve assembly 1 also experiences less turbulence. More specifically, the flapper assembly 10 results in less eddy flow between the first connector 9a and the second and fourth valve seats 5b, 5d. The flapper assembly 10 also results in less turbulence between the first connector 9a and the second and fourth valve seats 5b, 5d.

[0076] Eddy and turbulent flow have a negative impact on the amount of flow between the inlet port 2 and the outlet port 3 of the valve assembly 1 , that is, the baffle assembly 10 results in more efficient transport of fluid through the valve assembly 1 .

The fourth deflector 13d is disposed downstream of the third deflector 13c. It is contemplated that the fourth deflector 13d comprises a fourth prismatic deflector.

[0086] According to one aspect of the present disclosure, the fourth deflector 13d is manufactured using additive manufacturing techniques such as 3D printing. In an embodiment, the fourth deflector 13d is manufactured indirectly using additive manufacturing techniques such as 3D printing. In a particular embodiment, the manufacture of the fourth deflector 13d may involve selective laser sintering.

[0087] In an embodiment, the second deflector 13b and the fourth deflector 13d have similar shapes. In a particular embodiment, the second deflector 13b and the fourth deflector 13d have the same shape.

[0088] The third and fourth flow deflectors 13c, 13d are advantageously fixed relative to the second belly 14b. The second belly 14b connects the second valve seat 5b to the fourth valve seat 5d. The second belly 14b is distinct from the first belly 14a. It is contemplated that the third and fourth flow deflectors 13c, 13d could be mounted on the second belly 14b. It is also contemplated that the third and fourth flow deflectors 13c, 13d could be mounted on opposite sides of the second belly 14b.

[0089] The first deflector 13a, the second deflector 13b, the third deflector 13c and the fourth deflector 13d are different from each other.

[0090] The first flow deflector 13a is advantageously disposed between the first side 11a and the second side 11b of the valve assembly 1. The second flow deflector 13b is advantageously disposed between the first side 11a and the second side 11b of the valve assembly 1. The third flow deflector 13c is advantageously disposed between the first side 11a and the second side 11b of the valve assembly 1. The fourth flow deflector 13d is advantageously disposed between the first side 11a and the second side 11b of the valve assembly 1.

[0091] A fluid, such as a gaseous fluid, enters the valve assembly via the inlet port 2. The first flow deflector 13a then branches the flow into the fifth flow path 7e and the sixth flow path 7f. The fifth flow path 7e reaches the first valve seat 5a. After flowing through the first valve seat 5a, the fifth flow path 7e bypasses the first protrusion 12a. The fifth flow path 7e flows through the channel formed by the first protrusion 12a and the third flow deflector 13c. In this way, the third flow deflector 13c directs the fifth flow path 7e toward the second valve seat 5b. The fifth flow path 7e then flows through the second valve seat 5b, which is positioned downstream of the first protrusion 12a. After flowing through the second valve seat 5b, the fifth flow path 7e reaches the second valve member or second poppet valve 4b. The fifth flow path 7e ultimately reaches the outlet port 3.

[0092] The sixth flow path 7f reaches the third valve seat 5c. After flowing through the third valve seat 5c, the sixth flow path 7f bypasses the second protrusion 12b. The sixth flow path 7f flows through the channel formed by the second protrusion 12b and the third deflector 13c. In this way, the third deflector 13c guides the sixth flow path 7f toward the fourth valve seat 5d. The sixth flow path 7f then flows through the fourth valve seat 5d, which is arranged downstream of the second protrusion 12b. After flowing through the fourth valve seat 5d, the sixth flow path 7f reaches the fourth valve member or fourth poppet valve 4d. The sixth flow path 7f continues between the second valve member or second poppet valve 4b and the fourth valve member or fourth poppet valve 4d. In this way, the sixth flow path 7f can bypass the second connector 9b. As a non-limiting example, the sixth flow path 7f can bypass the second connector 9b from the side. The sixth flow path 7f ultimately reaches the outlet port 3.

[0093] The fifth flow path 7e is different from the sixth flow path 7f.

[0094] Due to the third deflector 13c, the fifth flow path 7e does not intersect with the sixth flow path 7f. More specifically, as Figure 4The fifth flow path 7e shown in FIG does not intersect the sixth flow path 7f between the first connector 9a and the second valve member 14b. Between the first valve seat 5a and the second valve member or second poppet 4b, the fifth flow path 7e resides on the first side 11a. More specifically, the fifth flow path 7e resides on the first side 11a of the valve assembly 1. Between the third valve seat 5c and the fourth valve member or fourth poppet 4d, the sixth flow path 7f resides on the second side 11b. More specifically, the sixth flow path 7f resides on the second side 11b of the valve assembly 1.

[0095] Because the fifth flow path 7e does not intersect the sixth flow path 7f, the valve assembly 1 having the third flow deflector 13c experiences less eddy current. The valve assembly 1 also experiences less turbulent flow. More specifically, the third flow deflector 13c causes less eddy current between the first connector 9a and the second belly 14b. The third flow deflector 13c also causes less turbulent flow between the first connector 9a and the second belly 14b.

[0096] Eddies and turbulence have a negative impact on the amount of flow between the inlet port 2 and the outlet port 3 of the valve assembly 1 , ie the third flow deflector 13c results in a more efficient transport of fluid through the valve assembly 1 .

According to certain aspects of the present disclosure, the fifth deflector 13e is a disk. It is contemplated that the fifth deflector 13e comprises a panel. According to certain aspects of the present disclosure, the fifth deflector 13e is a panel. In embodiments, the fifth deflector 13e is a fifth baffle member.

In an embodiment, the fifth deflector 13e is indirectly manufactured using additive manufacturing techniques such as 3D printing. In a particular embodiment, the manufacturing of the fifth deflector 13e may involve selective laser sintering.

[0099] The fifth flow deflector 13 e advantageously inhibits the flow paths 7 e , 7 f from crossing at or near the outlet port 3 of the valve assembly 1 .
