Description

Gas pipeline transportation pressure adjusting device Technical Field The invention relates to the technical field of gas pressure regulation, in particular to a gas pipeline transportation pressure regulating device. Background The fuel gas is a general term of gas fuel, and is mainly applied to civil and industrial fields by releasing heat through combustion, and mainly comprises four major types of natural gas, artificial fuel gas, liquefied petroleum gas and biomass gas. The natural gas comprises gas field gas, petroleum associated gas and the like, the artificial gas comprises carbonization gas, gasification gas and other forms, the liquefied petroleum gas is mainly propane and butane, and the biomass gas is prepared by biomass fermentation. Along with the development of science and technology, more and more families have put through gas, and current gas pipeline can not carry out atmospheric pressure and adjust when transmitting gas, when gas pressure changes, is difficult to in time discover and revise, often leads to can taking place danger when using gas because of the change of gas pipeline inside atmospheric pressure, remains to improve. Disclosure of Invention (One), solve the technical problems The technical problem to be solved by the invention is to overcome the difficulty, and provide the gas pipeline transportation pressure regulating device which can automatically regulate when the gas pressure in the gas pipeline changes, so that the terminal gas pressure is kept unchanged. (II) technical scheme In order to solve the technical problems, the technical scheme provided by the invention is that the gas pipeline transportation pressure regulating device comprises a pressure regulating device, wherein one end of the pressure regulating device is communicated with an air inlet pipe, the other end of the pressure regulating device is communicated with an air outlet pipe, the pressure regulating device comprises a device body, an air inlet pipe and an air outlet pipe which are respectively communicated with the air inlet pipe and the air outlet pipe are arranged on the device body, a reduced air passage and a regulating cavity which are communicated with the air inlet pipe are sequentially arranged in the device body, a C-shaped air passage which is communicated with the top of the regulating cavity is arranged on the reduced air passage, and a flat air passage which is communicated with the air outlet pipe is arranged at the top of the regulating cavity; The device is characterized in that an adjusting block capable of blocking the C-shaped air passage and the flat air passage is movably arranged in the adjusting cavity, a limiting cylinder is arranged at the top of the adjusting block, a groove for accommodating the limiting cylinder is formed in the device body, a rod body extending into the limiting cylinder is arranged in the groove, one end of the rod body is fixedly connected with the groove in a sleeved mode, and an adjusting spring is fixedly connected with the adjusting block at the other end of the rod body. As an improvement, a conical air passage is communicated between the air inlet passage and the contracted air passage. As an improvement, the adjusting block is provided with a round groove for accommodating the rod body. As an improvement, the bottom of the adjusting cavity is provided with a circular ring cavity which can support the adjusting block.
