Summary:The utility model relates to a reversed flow type on-site pressure-measuring apparatus for high-pressure construction, comprising a fracturing pump. The outlet of the fracturing pump is communicated with a well mouth by a pipeline and a valve, and is provided with an atmospheric valve. The reversed flow type on-site pressure-measuring apparatus for high-pressure construction is characterized in that one pipeline is communicated with the inlet and the outlet pipelines of the fracturing pump; a stop valve and a high-pressure needle valve are arranged on the pipeline; meanwhile, the inlet of the fracturing pump is respectively communicated with the exhausting branch pipe and the agitator tank of a truck-mounted blender by the pipeline, and stop valves are respectively arranged. The high-pressure needle valve is used for regulating pressure, which enables the pressure to stabilize. The utility model not only is convenient to operate, but also the workload of construction preparation is less, and the reversed flow type on-site pressure-measuring apparatus for high-pressure construction has no environmental pollution, and staffs' personal safety can be ensured.
