The application discloses a cutting synergist for liquefied petroleum gas and a preparation method thereof, and belongs to the technical field of cutting synergists. The cutting synergist is prepared by mixing the following components with the mass content: an alkyl ferrocene mixture 5-8%, n-octane 6-10%, ethylene glycol monoethyl ether 8-10%, isooctyl nitrate 10-15%, acetone 15-25%, and 200# solvent oil 25-45%. The application is a high-efficiency energy-saving synergist for cutting liquefied petroleum gas, and the performance of the liquefied petroleum gas after the addition of the synergist can reach and exceed the cutting performance level of the original petroleum gas and acetylene gas, and the liquefied petroleum gas can completely replace acetylene gas, natural gas and pure propane to be used as industrial gas for metal cutting. The product performance exceeds that of natural gas, industrial propane and the same kind of synergists on the market, and has a wide application prospect, and is a great breakthrough of industrial gas in the industrial field of China.

The application discloses a static characteristic alternative testing device for an indirect acting pressure regulator, which comprises a gas supply device, a high-pressure gas supply device, a main valve body control pipeline, a pressure control pipeline and a pilot pipeline, wherein the gas supply device is composed of a compressor unit and an air storage tank; the outlet of the air storage tank is connected with a main valve body testing pipeline and the pressure control pipeline respectively; a main valve body pipeline pressure control device, a main valve body of a measured pressure regulator and a main valve body pipeline flow regulating valve are sequentially installed on the main valve body control pipeline; the pressure control pipeline is connected with the main valve body pipeline pressure control device; and the outlet of the high-pressure gas supply device is connected with a high-pressure pressure reducing valve, a pilot of the measured pressure regulator and a pilot pipeline flow control device through the pilot pipeline in sequence. The device can complete the static characteristic testing of the pressure regulator by using test data in a low-pressure and small-flow testing environment, thereby reducing the energy consumption of testing and lowering the pressure and flow requirements of the testing system.
