Description

Technical Field

[0001] The invention relates to the technical field of marine distribution blocks, in particular to a marine LGIP main engine gas distribution block. Background Art

[0002] As the energy conservation and emission reduction requirements of the shipping industry become increasingly stringent, conventional fuels will find it difficult to meet both energy conservation and emission requirements at the same time, so new fuels will gradually replace traditional diesel as the fuel for marine main engines.

[0003] With the use of LPG fuel on marine main engines, the safety of the gas system is also facing great challenges, and safety is also the first design input to be considered, followed by the performance requirements of the main engine. LPG exists in the system in liquid form and is easy to vaporize. If a leak occurs, it is easy to gather. The density of vaporized LPG is higher than that of air, and it is easy to gather on the ground.

[0004] Therefore, when the host is running in LPG mode, the interfaces and pipelines of the entire host must not leak. The interfaces of the entire system are designed with leak detection holes and ventilation channels to prevent leakage from accumulating and reaching the explosion limit, causing safety accidents.

[0005] When running in LPG mode, the pressure of LPG needs to be increased to 600bar, so a corresponding hydraulic system is needed to ensure the pressure increase of LPG. According to the operating requirements of the main engine, the hydraulic control system is needed to control the time and amount of LPG injection into the main engine cylinder. In the entire gas system, due to the need for control and monitoring, multiple interfaces are designed. As the number of interfaces increases, the risk of leakage increases. Summary of the invention

[0006] The technical problem solved by the present invention is that in a gas system, due to the need for control and monitoring, multiple interfaces are designed, and as the number of interfaces increases, the risk of leakage increases.

[0007] In order to solve the above-mentioned technical problems, the technical solution of the present invention provides a marine LGIP main engine gas distribution block, wherein the distribution block includes a distribution block body, and the distribution block body is integrated with a hydraulic oil control valve for controlling the circulation of hydraulic oil, a hydraulic oil accumulator for storing pressure of hydraulic oil, a gas accumulator for storing pressure of gas, a gas inlet and outlet control valve for controlling the circulation of gas, and a sealing oil accumulator for storing pressure of sealing oil.

[0008] Optionally, a gas inlet channel, a gas return channel, a hydraulic oil channel and a leak detection channel are provided through the distribution block body. When a gas leak occurs, the leak detection channel performs a gas leak check.

[0009] Optionally, the gas inlet and outlet control valves are used to control the flow of gas in the gas inlet channel and the gas return channel.

[0010] Optionally, the hydraulic oil control valve is used to control the circulation of hydraulic oil in the hydraulic oil channel.

[0011] Optionally, a hydraulic oil control valve mounting position for mounting the hydraulic oil control valve is provided on the distribution block body.

[0012] Optionally, a gas inlet and outlet control valve installation position for installing the gas inlet and outlet control valve is provided on the distribution block body.

[0013] Optionally, a hydraulic oil accumulator mounting position for mounting the hydraulic oil accumulator is provided on the distribution block body.

[0014] Optionally, a gas accumulator mounting position for mounting the gas accumulator is provided on the distribution block body.

[0015] Optionally, a sealing oil accumulator mounting position for mounting the sealing oil accumulator is provided on the distribution block body.

[0016] The beneficial effects of the technical solution of the present invention are:

[0029] A marine LGIP main engine gas distribution block of this embodiment integrates the gas channel and the hydraulic oil channel on the distribution block; a solenoid valve is designed on the hydraulic oil channel of the distribution block to control the oil inlet time of the hydraulic oil, so that LPG is compressed and injected according to the needs of the main engine; a slight leakage of the hydraulic oil does not involve safety, but the leakage of the gas channel involves safety, and a leak detection ventilation channel is designed at the connection of all gas channels. The control valve of the entire system and the accumulator of the related hydraulic system are integrated on the distribution block, which saves space on the upper platform of the main engine and facilitates the gas leak detection operation.

[0030] In addition, the distribution block of this embodiment is also designed with a gas channel and a hydraulic oil channel, and is also designed with a ventilation channel and a control valve for controlling gas injection.
