Description

Technical Field

[0001] This disclosure relates to the field of testing gas-fired water heating equipment, specifically to a test bench for testing gas distribution frames and its components with the gas distribution frames. Background Technology

[0002] In gas-fired water heaters, a gas distributor is typically positioned between the gas valve and several burners to distribute the gas output from the valve to each burner. The gas distributor usually includes several gas nozzles corresponding to the burners. Each nozzle has a narrow outlet hole, through which the gas is ejected, drawing surrounding air into the corresponding burner for thorough mixing and combustion. However, in practical applications, deviations in the verticality of the nozzle outlet holes often affect the amount of air ejected when the gas enters the burner. Too much or too little air can cause noise or even vibration issues in the equipment. Utility Model Content

[0003] To overcome the problems existing in the related technologies, this disclosure provides a test bench for testing the verticality of the nozzle outlet of a gas distributor and its components with the gas distributor.

[0004] A first aspect of this disclosure provides a gas distributor test bench for testing the verticality of the nozzles of a gas distributor. The test bench includes a longitudinally extending top plate, a pair of side plates extending downwards from both ends of the top plate, and a front panel longitudinally connected between the pair of side plates. Bosses are respectively provided on opposite sides of the pair of side plates, and the top plate also has a longitudinally extending elongated opening. The test bench further includes a perforated plate extending longitudinally and having its longitudinal ends respectively disposed on the bosses of the pair of side plates. The perforated plate has at least one row of through holes distributed along the longitudinal direction, the at least one row of through holes located within the vertical projection area of ​​the elongated opening.

[0005] In some embodiments, the top edge of the front panel is spaced a certain distance from the top plate to form an observation opening.

[0006] In some embodiments, the top edge of the front panel is vertically higher than the top edge of the bosses of the pair of side panels.

[0007] In some embodiments, the top plate portion is recessed to form a longitudinally extending groove, and the test stage also includes a slider that can slide within the groove along the longitudinal direction.

[0008] In some embodiments, both the longitudinal end of the top plate and the slider are provided with mounting holes for fixing the gas distribution frame.

[0009] In some embodiments, the diameter of at least one row of through holes is in the range of 9.5 mm to 10.5 mm.

[0010] Another aspect of this disclosure provides a gas distribution frame test bench and a gas distribution frame assembly, which includes the aforementioned test bench and gas distribution frame. The gas distribution frame includes a body, a gas cavity formed within the body, an air inlet disposed on the body, and at least one row of nozzles. The body of the gas distribution frame is detachably fixed to the top plate of the test bench, and the at least one row of nozzles is located in an elongated opening in the top plate and is directly opposite all or part of at least one row of through holes in an orifice plate.

[0011] In some embodiments, the distance between the nozzle and the corresponding through hole is in the range of 90 mm to 110 mm.

[0012] The technical solutions provided by one or more embodiments of this disclosure may include the following beneficial effects: By setting a test bench with an orifice plate, the flow path of gas can be simulated using water flow to determine whether the verticality of the nozzle outlet of the gas distributor meets the requirements, thereby avoiding noise or even vibration problems caused by verticality deviation of the nozzle outlet. This test bench has a simple structure, is easy to operate, and can be used to test different models of gas distributors by changing the orifice plate and / or moving the slider.

[0017] The embodiments shown will now be described in detail with reference to the accompanying drawings. However, these embodiments do not represent all embodiments consistent with this disclosure, and any structural, methodological, or functional modifications made by those skilled in the art based on these embodiments are included within the scope of protection claimed in the appended claims.

[0018] like Figure 1In one embodiment, the gas distribution rack test bench 1 includes a longitudinally extending top plate 11, a pair of side plates 12 extending downward from both ends of the top plate 11, and a front panel 14 and a rear panel (not shown) longitudinally connected between the pair of side plates 12. In some embodiments, the test bench 1 further includes a bottom plate 12 connected to the bottom of the side plates 12, the front panel 14, and the rear panel. The top plate 11 has a longitudinally extending elongated opening 111, and the opposite sides of the pair of side plates 13 are respectively provided with bosses 131. The test bench 1 also includes a longitudinally extending perforated plate 30 with its longitudinal ends respectively disposed on the bosses 131 of the pair of side plates. The perforated plate 30 has at least one row of through holes 31 distributed along the longitudinal direction, and the at least one row of through holes 31 is located within the vertical projection area of ​​the elongated opening 111. The diameter of at least one of the above-mentioned through holes is in the range of 9.5mm to 10.5mm, such as 9.5mm, 10mm, 10.5mm, etc.

[0019] The top edge of the front panel 14 is spaced a certain distance from the top plate 11 to form an observation port 141. The top edge of the front panel 14 is vertically higher than the top edge of the protrusions 131 of the pair of side plates. The top plate 11 is partially recessed to form a longitudinally extending groove 112. The test stage 1 also includes a slider 20 that can slide longitudinally within the groove 12. Mounting holes 113 and 21 for fixing the gas distributor are provided on one longitudinal end of the top plate 11 and on the slider. In addition, the slider 20 is provided with positioning holes 22 for positioning it within the groove 112.

[0020] Figure 2 and Figure 3 The diagram shows an embodiment of a gas distributor test bench 1 and a gas distributor 40. The gas distributor 40 includes a body 41, a gas cavity 411 formed within the body, an air inlet 42 disposed on the body, and at least one row of nozzles 44. In this embodiment, the gas distributor has only one row of nozzles 44, and correspondingly, the orifice plate 30 also has only one row of through holes 31; in other embodiments, the nozzles and through holes on the orifice plate may be arranged in multiple rows. The body 41 of the gas distributor 40 is detachably fixed to the top plate 11 of the test bench 1. The gas distributor 40 can be mounted to the mounting holes 113 and 21 of the top plate and the slider respectively via mounting brackets 43 disposed at both ends of the longitudinal length of the body 41 using screws. In addition, gas distributors of different models and lengths can be matched and installed by sliding the slider 20.

[0021] After the above components are installed, at least one row of nozzles 44 of the gas distributor 40 is located in the narrow opening 111 of the top plate 11 and is directly opposite all or part of at least one row of through holes 31 of the orifice plate 30. The distance between the nozzles 44 and the corresponding through holes 31 is in the range of 90mm to 110mm, such as 90mm, 100mm, or 110mm. During testing, 160mbar of water is injected into the air inlet 42 of the distributor. The water flow simulates the flow path of the gas, passing through the gas chamber 411 and exiting through the nozzles 44. The water column can be observed through the observation port 141 of the test stand to see if it falls into the corresponding through hole 31; if not, it indicates that the verticality of the nozzle 44's outlet does not meet the requirements. Furthermore, since the top edge of the front panel 14 is vertically higher than the top edge of the boss 131 of the side panel, water splashing outside the test stand is prevented. In some embodiments, the base plate 12 of the test bench can be omitted, and the bottom of the test bench is directly connected to a drainage trough to drain the test water.

[0022] By setting up a test bench with an orifice plate, the flow path of natural gas can be simulated using water flow to determine whether the verticality of the nozzle outlet of the gas distributor meets the requirements. This avoids noise or even vibration problems caused by vertical deviation of the nozzle outlet. The test bench features a simple structure and is easy to operate. Different models of gas distributors can be tested by changing the orifice plate and / or moving the slider.
