Abstract

The invention discloses a device suitable for high-temperature and high-pressure gas pulsation adjustment. A tube connector is arranged on a magnet mounting base, through an air inlet pipe and an airoutlet pipe are connected, the magnet is cooled; the magnet mounting base is fixed on a front cavity shell, the front cavity shell is an air containing cavity; the front cavity shell is arranged on anadapter mounting base and is connected with an incoming flow channel; a sensor a is arranged between the adapter mounting base and the front cavity shell; a rear cavity shell mounting base is connected with the front cavity shell, the rear cavity shell mounting base and the front cavity shell are in clearance to form an air outlet channel; a rear cavity shell is arranged on the rear cavity mounting base; a sensor b is arranged on a rear cavity mounting seat, a cavity is defined by the piston and an adjusting screw cap, a spring is arranged in the cavity, a piston mounting seat is fixed on therear cavity mounting seat; the adjusting screw cap is fixedly connected with the piston mounting base through threads; the rear cavity shell, the rear cavity mounting base and the piston mounting seat form a pressure equalizing cavity, an air pressure regulator is arranged on the piston surface of the piston. According to the device, a constant-constant airflow is adjusted to be a controllable pulsating gas flow, a supporting device is used for processing a gas working medium with a relatively high temperature.

Description

technical field [0001] The invention relates to the technical field of regulating devices, in particular to a device suitable for high temperature and high pressure gas pulse regulation. Background technique [0002] Adjusting the flow parameters of the gas working medium to meet the requirements of equipment and pipe networks or meet the conditions of scientific research and testing is the core content of the engineering design field. In addition to the conventional adjustment of parameters such as pressure and speed, it also includes changes to the movement characteristics of the gas working medium , the "pulsation" feature is relatively common in the flow of gas working fluid. In practical applications, it mainly involves the adjustment of the pulsation energy, including the amplification, reduction and period of the "pulsation" amplitude, how to efficiently, stably and reliably align it. Regulation and control are the key points, and the characteristics of high-temperatu...

[0002] Adjusting the flow parameters of the gas working medium to meet the requirements of equipment and pipe networks or meet the conditions of scientific research and testing is the core content of the engineering design field. In addition to the conventional adjustment of parameters such as pressure and speed, it also includes changes to the movement characteristics of the gas working medium , the "pulsation" feature is relatively common in the flow of gas working fluid. In practical applications, it mainly involves the adjustment of the pulsation energy, including the amplification, reduction and period of the "pulsation" amplitude, how to efficiently, stably and reliably align it. Regulation and control are the key points, and the characteristics of high-temperature and high-pressure gas further increase the difficulty of its design. At present, there are no normative documents for such devices in China, and they are designed according to actual needs and conditions.
