[0002] At present, there is a common problem in the whole liquid-driven hydrogen compressor: the connection mode of the exhaust pipe valve parts is a large number of pipe connections, which are connected pairwise. This mechanism not only has many leakage points, but also has the hidden danger of hydrogen leakage. If leakage occurs, the leaked hydrogen mixes with air and reaches the limit concentration, an explosion and fire accident will occur. Therefore, it is extremely important to reduce the pipe connection points as much as possible.

[0003] At the same time, the exhaust pipe is complex, involving a large number of components, resulting in a crisscross of pipelines, low assembly production efficiency, greatly increasing the after-sales maintenance cost, and the maintenance will also affect the judgment of the staff due to the intricate pipelines.

A first medium-pressure solenoid valve is fixed on the left side of the top of the bottom plate. A second medium-pressure needle valve is installed on the right side of the center at the bottom of the front end of the control panel. A first medium-pressure needle valve is installed on the left side of the bottom of the front end of the control panel, and a connecting pipe is installed between the top of the first medium-pressure needle valve and the first medium-pressure solenoid valve. The front end of the first medium-pressure needle valve is fixed with an intermediate three-way pipe, and a medium-pressure unloading valve is fixed at the top of the intermediate three-way pipe. An end three-way pipe is fixed between the front end of the intermediate three-way pipe and the integrated valve block. A medium-pressure check valve is fixed at the lower right of the front end of the control panel, and the medium-pressure check valve is communicated with the second medium-pressure needle valve.
