Pressure regulating and ejecting integrated device for LPG mixed air

Abstract

The invention discloses a pressure regulating and ejecting integrated device for LPG mixed air. At present, an air mixer is used under the condition that the air mixing ratio is not constant, and the air mixer is large in device size, complex in structure and too high in cost, is only a device for tests and cannot be put on production in a batch manner to be directly used by users. The pressure regulating and ejecting integrated device for LPG mixed air comprises an air inlet, a sealing piston, an axial air outlet, a pressure regulating sleeve, a pressure regulating push rod, a wire rope, a rolling shaft, a pressure regulating pull rod, a stroke regulating nut, a pressure regulating lever, a lower shell, a fixing groove, a screw, an upper shell, a protecting slice, a pressure regulating spring, a thread protecting cover, a pressure regulating nut, a locking nut, a pressure regulating membrane, an air suction inlet, an ejecting spray pipe, a mixing chamber, a diffusion chamber and an air outlet. According to the pressure regulating and ejecting integrated device, the pressure of liquefied petroleum gas is controllable and adjustable, the ejecting mixing ratio can be debugged by replacing a nozzle, and the pressure regulating and ejecting integrated device has the advantages of being high in reliability and practicality, low in cost, simple and reasonable in structure, convenient to install and maintain and the like.

Description

technical field [0001] The invention belongs to the technical field of gas exchange application, and in particular relates to a pressure regulating injection integrated device for liquefied petroleum gas mixed with air, and the mixed gas is used instead of natural gas. Background technique [0002] In the application technology of gas exchange, due to the variety of urban gas sources and the complex links involved in the supply of gas, the production of burning appliances, and the gas combustion test, it is necessary to use alternative gas (that is, replacement gas). In the common gas exchange process, it is not uncommon to use liquefied petroleum gas mixed with air instead of natural gas. In order to ensure that the mixed gas after liquefied petroleum gas mixed with air has the same combustion characteristics and thermal performance indicators as the original reference gas (natural gas), The liquefied petroleum gas must be adjusted and injected to facilitate the direct use ...

AI Technical Summary

Problems solved by technology

[0003] At present, there is no special pressure-regulating injection device for directly connecting the LPG cylinder and the cooker (the front main pipe of the cooker) in China. Generally, a gas mixer for mixing liquefied petroleum gas and air has been developed based on the gas distribution technology. The advantages of automatic adjustment of the gas mixing ratio, but the use of this kind of gas mixing machine is under the condition that the gas mixing ratio is not fixed, and the device size of the gas mixing machine is large, the structure is complicated, and the cost is too high. It is only used for testing. The device cannot be put into mass production and provided to users for direct use
