Hydraulic sub station trailer continuous gas supply device

Abstract

The invention relates to a hydraulic sub station trailer continuous gas supply device comprising a gas tank and a pneumatic ball valve. One end of a pipeline of the pneumatic ball valve is communicated with the gas tank through one valve, the other end of the pipeline of the pneumatic ball valve is communicated with one output pipeline, a pneumatic switch of the pneumatic ball valve controls a hose to connect to the female end of a self-seal hose fast joint through a pneumatic valve, the female end of the self-seal hose fast joint is fastened to a male end of a self-seal hose fast joint, and the other end of the male end of the self-seal hose fast joint is connected to a pneumatic valve control device; the output pipeline is connected to a filter and a three-way valve, a manual ball valve is arranged between the filter and the pneumatic ball valve, and a pressure regulating valve is arranged between the three-way valve and the filter. By the aid of the device, the problem that the gas of a trailer is insufficient during transportation of the hydraulic sub station trailer is solved, and the hydraulic sub station trailer is guaranteed operating safely and smoothly.

Description

technical field [0001] The invention belongs to the technical field of compressed natural gas storage and transportation devices, in particular to a continuous gas supply device for hydraulic substation trailers. Background technique [0002] With the continuous promotion of clean energy in the country, the application of natural gas has developed rapidly. More and more natural gas tractors have been favored, but there are relatively few natural gas filling stations. During the transportation of hydraulic sub-station trailers, there are no The gas station and the transport vehicle cannot operate, and natural gas and hydraulic oil coexist in the trailer of the hydraulic substation. Natural gas is a mixture of oil and gas, which is easy to damage the engine, making it difficult for the trailer of the hydraulic substation to be used with the natural gas tractor. In the case of insufficient gas source Under these conditions, it is difficult to ensure the safe and smooth operatio...
