A burner testing fixture

Abstract

This utility model discloses a burner testing fixture, comprising: a fixing structure for clamping the burner, the burner having at least one gas passage inside; a gas supply structure; and a gas float structure. This utility model utilizes the gas supply structure to introduce gas into the burner's gas passage, and the float moves along the gas passage under the action of the gas. If the float can move within the gas passage, the gas passage is unobstructed; if the float cannot move within the gas passage, the gas passage is blocked. Furthermore, when the float can move within the gas passage, the user can observe whether there is a difference between the actual travel distance of the float within the gas passage and the standard travel distance, and accordingly determine whether there is a difference between the actual diameter of the gas passage outlet and the standard diameter of the gas passage outlet. This utility model does not require the use of gas, making it safer and more convenient.

Description

Technical Field

[0001] This utility model belongs to the field of burner technology, specifically relating to a burner testing fixture. Background Technology

[0002] A burner is a device that converts substances into heat energy through a chemical reaction called combustion; examples include household water heaters and gas stove burners. In related technologies, when a burner is working, air and fuel are mixed in an appropriate ratio using a premixing device to ensure complete combustion; therefore, burners generally have a gas flow path.

[0003] Because burners produce an open flame during combustion, burner testing is necessary to improve their safety. In related technologies, this testing is conducted through an open flame test. During the open flame test, air and fuel are mixed in an appropriate ratio using a premixing device and introduced into the gas passage. The mixture is then ignited at the burner nozzle to check for blockages in the gas passage. If ignition is successful, the gas passage is unobstructed; if ignition fails, the gas passage is blocked.

[0004] However, when this open flame test method can achieve ignition, it is difficult for users to intuitively detect whether there is a difference between the actual diameter of the nozzle in the gas passage and the standard diameter of the nozzle in the gas passage. Moreover, the open flame test requires the use of a certain amount of gas, which not only increases production costs but also poses a certain degree of danger. Utility Model Content

[0044] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.

[0045] See Figures 1 to 20This utility model discloses a burner testing fixture, comprising: a fixing structure 10 for clamping a burner 20, the burner 20 having at least one gas passage 201 inside; a gas supply structure 30 having at least one gas supply port 301, the gas passage 201 having a corresponding gas supply port 301 at its inlet 202, the gas supply port 301 of the gas supply structure 30 being connected to the corresponding inlet 202 of the gas passage 201; and a gas float structure 40 including at least one gas passage 401, a float 402 being disposed inside the gas passage 401, the gas passage 401 extending along a first direction, the gas passage 201 having a corresponding gas passage 401 at its outlet 203, the gas passage 401 having an inlet 403, the gas passage 201 having an outlet 203 being connected to the corresponding gas passage 401 inlet 403.

[0046] This invention features a gas float structure 40 and a gas supply structure 30. Gas is introduced into the gas passage 201 of the burner 20 via the gas supply structure 30. The gas passes through the gas supply structure 30 and the gas passage 201 into the gas passage 401. The float 402 moves along the gas passage 401 under the influence of the gas. If the float 402 can move within the gas passage 401, the gas passage 201 is unobstructed; if the float 402 cannot move within the gas passage 401, the gas passage 201 is blocked. Furthermore, when the float 402 can move within the gas passage 401, the user can observe whether there is a difference between the actual travel distance of the float 402 within the gas passage 401 and its standard travel distance. This allows the user to determine whether there is a difference between the actual diameter of the outlet 203 of the gas passage 201 and its standard diameter. This invention does not require the use of gas, making it safer and more convenient to use.

[0047] It should be noted that the float 402 is a plastic float, and the predetermined gas pressure and gas flow provided by the gas supply structure 30 can drive the float 402 to move within the gas channel 401 when the gas channel 201 is unobstructed.

[0048] It should be noted that one or more gas passages 201 can be provided inside the burner 20.

[0049] For example, see Figure 3 as well as Figure 4The burner 20 is provided with four gas passages 201. All outlets 203 of one gas passage 201 correspond to one gas passage 401. That is, the four gas passages 201 correspond to the four gas passages 401 respectively. At this time, the gas float structure 40 includes four gas passages 401 and four floats 402. The shape of the floats 402 is adapted to the shape of the corresponding gas passages 401. The floats 402 are strip-shaped.

[0050] Under the premise that the gas pressure and flow rate provided by the gas supply structure 30 are constant, the standard stroke of the float 402 in the gas channel 401 is set as H, and the standard diameter of the outlet 203 of the corresponding gas channel 201 is D.

[0051] The actual travel distance of float 402 within the first gas channel 401 is h1. If h1 ≠ H, the user records the actual diameter of the outlet 203 of the corresponding gas channel 201 as d1, where d1 ≠ D. This indicates that the actual diameter of the outlet 203 of the gas channel 201 differs from the standard diameter of the outlet 203 of the gas channel 201. Consequently, the user needs to mark the gas channel 201 and further inspect and confirm the actual size of d1, or consider the gas channel as defective and process it accordingly. If h1 = H, then d1 = D, and the actual diameter of the outlet 203 of the gas channel 201 is equal to the standard diameter of the outlet 203 of the gas channel 201.

[0052] Similarly, the above method is used to confirm whether there is a difference between the actual diameter of the outlet 203 of the other three gas passages 201 and the standard diameter of the outlet 203 of the gas passage 201.

[0053] In this embodiment of the utility model, the fixing structure 10 includes a first clamping member 101 and a second clamping member 102. The first clamping member 101 is disposed on the first side of the burner 20, and the second clamping member 102 is disposed on the second side of the burner 20. The first side of the burner 20 and the second side of the burner 20 are respectively located on opposite sides of the burner 20.

[0054] For example, see Figure 4 The first clamping member 101 is provided on the right side of the burner 20, and the second clamping member 102 is provided on the left side of the burner 20, so as to clamp the burner 20 by using the first clamping member 101 and the second clamping member 102 to improve the installation stability of the burner 20.

[0055] In this embodiment of the present invention, a pipe portion 204 protrudes from the inlet 202 of the gas passage 201, and the pipe portion 204 is disposed on the first side of the burner 20; the first clamping member 101 includes a first inner limiting plate 1011, a first outer limiting plate 1012, and a first plug-in plate 1013 connected to each other, the first inner limiting plate 1011 and the first plug-in plate 1013 have an included angle β1, the first inner limiting plate 1011 is disposed on the inner side of the first outer limiting plate 1012, and the first inner limiting plate 1011 and the first outer limiting plate 1012 are arranged parallel to each other; the first inner limiting plate 1011... The inner wall of plate 1011 abuts against the outer wall of the first side of burner 20. The first inner limiting plate 1011 is provided with a first connecting hole 1014 for the pipe section 204 to pass through. The inner wall of the first outer limiting plate 1012 abuts against the outer wall of the pipe section 204, and the first outer limiting plate 1012 is provided with a second connecting hole 1015. The second connecting hole 1015 is connected to the inlet 202 of the gas passage 201. The first plug-in plate 1013 is provided with a first plug-in hole 1016, and the upper part of the first side of burner 20 is inserted into the first plug-in hole 1016.

[0056] For example, see Figure 4 , Figure 5 , Figure 12 , Figure 13 as well as Figure 14 The first connecting hole 1014 is located in the middle of the first inner limiting plate 1011, and the second connecting hole 1015 is located in the middle of the first outer limiting plate 1012.

[0057] When the burner 20 is clamped using the first clamping member 101, the upper part of the first side of the burner 20 is inserted into the first insertion hole 1016 of the first insertion plate 1013, thereby limiting the upper part of the first side of the burner 20 in the front-back direction (Y-axis direction of the coordinate system); the tube part 204 of the burner 20 can be supported in the first connecting hole 1014, and the lower part of the first side of the burner 20 is limited in the left-right direction (X-axis direction of the coordinate system) by the first inner limiting plate 1011 and the first outer limiting plate 1012.

[0058] In this embodiment of the present invention, the outlet 203 of the gas passage 201 is located at the top of the burner 20. The second clamping member 102 includes a second upper insertion plate 1021, a second limiting plate 1022, and a second lower insertion plate 1023 connected in sequence. The second limiting plate 1022 and the second upper insertion plate 1021 have an included angle β2, and the second limiting plate 1022 and the second lower insertion plate 1023 have an included angle β3. The second upper insertion plate 1021 is provided with a second upper insertion hole 1024, and the upper part of the second side of the burner 20 is inserted into the second upper insertion hole 1024. The inner sidewall of the second limiting plate 1022 abuts against the outer sidewall of the second side of the burner 20. The second lower insertion plate 1023 is provided with a second lower insertion hole 1025, and the lower part of the second side of the burner 20 is inserted into the second lower insertion hole 1025.

[0059] For example, see Figure 4 , Figure 5 , Figure 12 , Figure 17 as well as Figure 18 When the burner 20 is clamped using the second clamping member 102, the upper part of the second side of the burner 20 is inserted into the second upper insertion hole 1024 of the second upper insertion plate 1021, and the lower part of the second side of the burner 20 is inserted into the second lower insertion hole 1025 of the second lower insertion plate 1023. Thus, the second upper insertion plate 1021 limits the upper part of the second side of the burner 20 in the front-back direction (Y-axis direction of the coordinate system), and the second lower insertion plate 1023 limits the lower part of the second side of the burner 20 in the front-back direction (Y-axis direction of the coordinate system). The inner wall of the second limiting plate 1022 abuts against the outer wall of the second side of the burner 20 to limit the second side of the burner 20 in the left-right direction (X-axis direction of the coordinate system).

[0060] In this embodiment of the invention, the included angle β1 ranges from 100° to 170°; the included angle β2 ranges from 100° to 170°; and the included angle β3 ranges from 100° to 170°.

[0061] For example, see Figure 15 The included angle β1 is 105°; see reference Figure 18 The included angle β2 is 158° and the included angle β3 is 132°.

[0062] The specific sizes of the included angles β1, β2, and β3 are determined based on the actual application and are not limited thereto.

[0063] In this embodiment of the utility model, the fixing structure 10 further includes a stop block 103 and a base 104. The base 104 is provided with a first mounting groove 1041, a second mounting groove 1042, a third mounting groove 1043, and a fourth mounting groove 1044 arranged in a circumferential sequence. The second clamping member 102 further includes an auxiliary wing plate 1026, which is connected to a second limiting plate 1022. A first inner limiting plate 1011 is inserted into the first mounting groove 1041, and the auxiliary wing plate 1026 and the stop block 103 are both inserted into the third mounting groove 1043. The gas float structure 40 includes a housing 404, which has a first mounting part 4041 and a second mounting part 4042. The first mounting part 4041 is inserted into the second mounting groove 1042, and the second mounting part 4042 is inserted into the fourth mounting groove 1044.

[0064] For example, see Figure 1 as well as Figure 9 The first mounting slot 1041 is located on the right side of the base 104, the second mounting slot 1042 is located on the front side of the base 104, the third mounting slot 1043 is located on the left side of the base 104, and the fourth mounting slot 1044 is located on the rear side of the base 104, so that the gas float structure 40 can be connected to the base 104, making the overall structure more compact.

[0065] See Figure 4 Since the first clamping member 101 and the gas supply structure 30 are both located on the right side of the burner 20, and the second clamping member 102 is located on the left side of the burner 20, when the gas supply structure 30 supplies gas into the gas passage 201 of the burner 20, the burner 20 is subjected to a leftward thrust, and the stop block 103 supports the burner 20 on the left side to maintain the balance of the burner 20.

[0066] In this embodiment of the utility model, the fixing structure 10 further includes a locking bolt 105, which is inserted between the first inner limiting plate 1011 and the second limiting plate 1022 along the second direction to lock the first inner limiting plate 1011 and the second limiting plate 1022.

[0067] For example, see Figure 8 as well as Figure 9 Two locking bolts 105 are provided. The first inner limiting plate 1011 is provided with a third connecting hole 1017 that mates with the locking bolts 105, and the second limiting plate 1022 is provided with a fourth connecting hole 1027 that mates with the locking bolts 105. The locking bolts 105 can improve the installation stability of the first clamping member 101, the second clamping member 102, and the burner 20.

[0068] In this embodiment of the invention, the burner 20 includes at least two burners 205, which are arranged side by side along a third direction, and a gas passage 201 is provided on the burner 205.

[0069] For example, see Figures 7 to 12 The burner 20 includes four burner bars 205. Of course, in other embodiments, the burner 20 may include two burner bars 205, three burner bars 205, or five burner bars 205, etc. The specific number of burner bars 205 is determined according to the actual situation and is not limited.
