Abstract

The invention relates to the technical field of diesel locomotives, in particular to a novel expansion tank. The novel expansion tank comprises a U-shaped board, flat boards, a swash plate, a separation board, embedded water pipes and a pressure valve. The U-shaped board is welded to the flat boards to form a tank body. The swash plate, the separation board and the embedded water pipes are installed in the tank body. The pressure valve is connected to the top of the tank body. The U-type board and the three flat boards are welded to form the tank body, so that the embedded water pipes are conveniently arranged in the tank body in advance, space is better used, and pipe distribution is facilitated. The separation board is arranged in the tank body so that a high-temperature water tank body and a low-temperature water tank body can be separated, mix of high-temperature water and low-temperature water can be avoided, and cooling of a low-temperature system of a diesel engine can be facilitated; a balance hole is formed, so that water adding is convenient and the water level is conveniently balanced when the diesel engine stops working; a ventilation hole is formed, so that equal pressure of the high-temperature water tank body and the low-temperature water tank body is achieved and the water level of the high-temperature water tank body and the water level of the low-temperature water tank body are balanced conveniently; requirement can be satisfied through only one pressure valve.

Description

technical field [0001] The invention relates to the technical field of diesel locomotives, in particular to a novel expansion water tank. Background technique [0002] At present, the diesel engines on most diesel locomotives use two separate high and low temperature cooling systems. The temperature of the high temperature water system is much higher than that of the low temperature water system. The traditional water tanks either do not distinguish between high and low temperature water tanks or are completely separated. The water tank without high and low temperature is likely to cause high and low temperature water to cross each other. After the high and low temperature water is mixed in the water tank, it enters the diesel engine through the water supply pipe, which makes the temperature of the low temperature water rise, resulting in insufficient cooling capacity of the low temperature water system, which affects the air intake of the diesel engine and the cooling of the...
