Problems solved by technology

In the past, the fuel collection block was installed after the oil pipe was installed on the diesel engine. The two halves of the oil collection block were mainly used to cover several oil pipes and clamped with bolts. The installation was not very convenient and the sealing was not very good.

Embodiment Construction

[0011] Depend on figure 1 It can be known from the schematic diagram that the high-pressure fuel leakage alarm collection block of the present invention includes a sleeve 8 , an oil collection inner chamber 3 , an O-ring 2 and an oil collection outer chamber 4 .

[0012] There is an oil outlet hole on the casing 8, and the oil collection inner cavity 3 is set on the casing 8, and the cavity of the oil collection inner cavity 3 corresponds to the oil outlet hole on the casing 8, and the oil collection inner cavity 3 There is an annular groove in the middle of the surfaces on both sides, and an O-ring 2 is embedded in the annular groove.

[0013] The oil-collecting outer chamber 4 is arranged outside the oil-collecting inner chamber 3. The oil-collecting outer chamber 4 is C-shaped, and both ends of the oil-collecting outer chamber 4 have thread structures, and one end of the oil-collecting outer chamber 4 is close to the The other end of the union nut 7 is fixed with a lock nu...

Abstract

The invention relates to a collecting block for high pressure fuel leak, which comprises a sleeve, a fuel collecting inner cavity, O-shaped seal rings and a fuel collecting outer cavity, wherein the sleeve is sheathed with the fuel collecting inner cavity; annular grooves are formed at the middle parts of the upper surface and the lower surface of the fuel collecting inner cavity; the O-shaped seal rings are embedded into the annular grooves; the fuel collecting outer cavity is arranged outside the fuel collecting inner cavity; one end of the fuel collecting outer cavity is pushed against a union nut; the other end of the fuel collecting outer cavity is fixed by a lock nut; the sleeve is sheathed with the lock nut directly; and copper gaskets are connected between the fuel collecting inner cavity and the fuel collecting outer cavity. The collecting block has the advantages that the newly-designed collecting block for the fuel leak comprises the fuel collecting inner cavity, the O-shaped seal rings, the copper gaskets, the sleeve, a tube connector and the fuel collecting outer cavity; the collecting block with the structure is sheathed before a heading of a fuel tube for tube line bending; one collecting block for the fuel leak is matched with one fuel tube; the mounting is convenient; and the axial and radial sealing is satisfactorily ensured.

Description

technical field [0001] The invention relates to a high-pressure fuel oil leakage collection block, in particular to a high-pressure fuel oil leakage collection block which is easy to install and can well ensure axial and radial sealing. Background technique [0002] On sea transport ships, due to the rupture or leakage of the high-pressure fuel pipeline of the diesel engine, which splashes onto hot surfaces such as turbochargers and exhaust pipes, fires occur in the machinery space, causing damage to the ship’s property and endangering the safety of personnel. Therefore, it must be installed on the high-pressure fuel pipeline. A device capable of collecting leaked fuel when fuel leaks, and giving an alarm when the leaked fuel reaches a certain amount. [0003] The structure of the current diesel engine high-pressure pipeline leakage alarm device is as follows: on all external high-pressure fuel delivery pipelines between the high-pressure fuel pump and the fuel nozzle of the...
