Axial-flow type gas pressure regulator capable of increasing retardation internal friction force through variable-speed dynamic balance

Abstract

The invention discloses an axial flow type gas pressure regulator capable of increasing retardation internal friction force through variable-speed dynamic balance, which comprises a gas inlet and a flange plate, the flange plate is arranged on one side of the gas inlet, one side of the flange plate is movably connected with a gas inlet valve, and the upper part of the gas inlet valve is fixedly connected with a main pipe. According to the axial-flow type fuel gas pressure regulator capable of increasing the retardation internal friction force through variable-speed dynamic balance, when high-pressure gas enters the pressure regulator through the guide pipe, a good partition plate buffering mechanism is arranged, the high-pressure gas is not prone to causing impact on the pressure regulating assembly, and therefore the service life is prolonged; during pressure regulation, a certain air pressure difference can be accurately maintained by utilizing upward movement and falling of the movable disc and standby regulation of the pressure regulating pipe, so that the gas outlet speed of gas is equal to the combustion speed, and flame can be kept in a stable state only when dynamic balance is achieved within a certain range, and therefore, safe combustion of gas is realized; and the use safety of the voltage regulator is improved to a great extent.

Description

technical field [0001] The invention relates to the technical field of gas pressure regulators, in particular to an axial flow gas pressure regulator with variable speed dynamic balance and increased blocking internal friction. Background technique [0002] The gas pressure regulator is commonly known as the pressure reducing valve, also known as the gas pressure regulating valve. It is a device that automatically changes the gas flow through the intake valve to keep the outlet gas at the specified pressure. The pressure regulator is a special valve on the gas pipeline. A device that maintains a stable downstream pressure regardless of how the flow of gas and upstream pressure changes. An ideal gas supply system delivers gas from the wellhead to the end user without the need for a pressure regulator. The condition for such an ideal supply system to be maintained is that the user demand is constant. , the supply capacity of the mine is constant, and at the same time the two a...

Problems solved by technology

[0006] The object of the present invention is to provide an axial-flow gas pressure regulator with variable-speed dynamic balance and increased internal friction force, so as to solve the existing gas pressure regulator proposed in the above-mentioned background technology. When the inside of the regulator is not equipped with a good buffer mechanism, the high-pressure gas is easy to cause impact on the regulator. Long-term use will directly cause damage to the core regulator components of the regulator, thereby shortening the service life. A single diaphragm activity cannot accurately maintain a certain air pressure difference, so that the gas outlet speed is not equal to the combustion speed. If the diaphragm is damaged or the air pressure increases over a long period of time, it will directly cause the outlet pressure to be too high. The gas outlet speed will be greater than the combustion speed, causing the flame to burn at a certain distance away from the fire hole, or even fire off. When the fire off, the gas will continue to leak out, forming a large amount of toxic or explosive gas in the air, which can easily cause accidents.
