Benefits of technology

This patented technology allows for better control over how much air enters into an engine's cylinders during operation without causing damage due to excessive pressure differences across different parts within it. It also helps improve efficiency when supplying fuels through small holes on specific areas of the manifold plate used with these engines.

Problems solved by technology

This patented describes how important factors are involved when designing an engine system that uses gases from one part (the compressed section) to another part called the turbines. These components have many technical features - they require effective mixing of fuels before being injected into these areas where their functions can take place effectively. Additionally, there must also prevent damage caused by debris blocking certain openings within the systems' flow paths.

Embodiment 1

[0036] Such as figure 1 As shown, the nozzle flange for preventing foreign matter includes a filter screen 1 , a throttling orifice plate 2 and a fixing part 3 arranged inside the nozzle flange.

[0037] Specifically, the filter screen 1 is used to filter foreign matter entering the nozzle flange. The filter screen 1 has a ring structure, and the nozzle flange is provided with at least one layer of filter screen 1. The mesh number and wire diameter of the filter screen are not limited. Choose the hole diameter. In one embodiment of this application, the nozzle flange is provided with a layer of filter screen 1 .

[0038] Throttle orifice 2 is arranged on the downstream of filter screen 1, and is coaxial with filter screen 1, and throttle orifice 2 is annular structure, and throttle orifice 2 is provided with a plurality of hole structures 21, and hole structure 21 The positions correspond to the nozzle flange fuel inlet holes one by one. In addition, the hole diameter of the ho

Embodiment 2

[0042] Such as figure 2 As shown, the nozzle flange for preventing foreign matter includes a first clamping plate 4 , a filter screen 1 , a throttling orifice plate 2 and a fixing part 3 arranged inside the nozzle flange. In an embodiment of this application, the first splint 4, the filter screen 1, and the orifice plate 2 are arranged coaxially in sequence.

[0043] Wherein, the first splint 4 is arranged upstream of the filter screen 1 , the first splint 4 is in an annular structure, and the first splint is provided with a hollow structure 41 corresponding to the filter portion 11 of the filter screen 1 . By arranging the first splint on the nozzle flange, the filter screen is positioned, and the operation convenience of disassembly and maintenance such as filter screen cleaning and replacement is improved.

[0044] The filter screen 1 is used to filter the foreign matter entering the nozzle flange. The filter screen 1 has a ring structure, and the nozzle flange is equipped w

Embodiment 3

[0049] Such as image 3 As shown, the nozzle flange for preventing foreign matter includes a filter screen 1 , a throttle orifice plate 2 , a second clamping plate 5 and a fixing part 3 arranged inside the nozzle flange. In one embodiment of this application, the filter screen 1 , the second clamping plate 5 and the throttle orifice plate 2 are arranged coaxially in sequence.

[0050] Wherein, the second splint 5 is arranged downstream of the filter screen 1 , the second splint 5 is in an annular structure, and the second splint 5 is provided with a hollow structure 51 corresponding to the filter portion 11 of the filter screen 1 . By arranging the second splint on the nozzle flange, the filter screen is positioned, and the operation convenience of the filter screen cleaning, replacement and other disassembly and maintenance is improved.

[0051] The filter screen 1 is used to filter the foreign matter entering the nozzle flange. The filter screen 1 has a ring structure, and the

Abstract

The invention discloses a nozzle flange capable of preventing foreign matters and a combustion chamber. The nozzle flange comprises a filter screen, a throttling orifice plate and a fixing part which are arranged in the interior of the nozzle flange, the filter screen is used for filtering the foreign matters entering the nozzle flange, the throttling orifice plate is arranged on the downstream of the filter screen and is coaxial with the filter screen, and the fixing part is used for carrying out compaction and fixation on the filter screen and the throttling orifice plate. According to the nozzle flange capable of preventing the foreign matters, a foreign matter preventing structure is arranged on the nozzle flange, the situation that the fuel jet flow is uneven due to the fact that a fuel spraying hole is blocked by the residual foreign matters is prevented, meanwhile, a throttling assembly is matched, the effective area of a fuel channel is adjusted, and the difference of the fuel flow among nozzles is reduced.
