Embodiment Construction
[0010] As shown in the figure, the combustible gas enters the gas valve unit from the combustible gas inlet, passes through the internal combustible gas pipeline and accessories, and finally flows out from the combustible gas outlet. Among them, the gas pressure regulating valve can adjust the pressure of combustible gas; the gas actuator, rocker arm and gas throttle can control the flow of combustible gas; The signal is output to the peripheral controller; the combustible gas detector can detect the concentration of combustible gas outside the pipeline and in the valve box, and it can send the concentration signal to the peripheral controller; when the temperature and pressure of the combustible gas are abnormal or zero When there is combustible gas leakage between components, the above signals will be transmitted to the peripheral controller, and the controller will control the on-off of natural gas according to the control program; the flame arrester can ensure the propagati...

The invention provides a multifunctional combustible gas valve piece unit, and relates to the field of valve piece units. The multifunctional combustible gas valve piece unit comprises a valve box, a combustible gas detector, two air or inert gas filling openings, a fuel gas pressure temperature sensor, a fuel gas actuator, a rocking arm, a fuel gas throttle valve, a manual ball valve, a fire barrier, an emergency switching-off electromagnetic valve, a fuel gas pressure adjusting valve, a grounded wire and a pneumatic stop valve; the combustible gas detector and the two air or inert gas filling openings are connected to the exterior of the valve box, and the fuel gas pressure temperature sensor, the fuel gas actuator, the manual ball valve, the fire barrier, the emergency switching-off electromagnetic valve, the fuel gas pressure adjusting valve and the pneumatic stop valve are connected to a pipe inside the valve box. The gas valve piece unit can be used on a natural gas power ship and can be used in other combustible gas transporting pipes, and diversity requirements for combustible gas using are guaranteed.
Description
technical field [0001] The invention relates to the field of valve units, in particular to combustible gas valve units. Background technique [0002] In the process of transmission and storage of combustible gas, the combustible gas needs to be adjusted and monitored during the transmission and storage process. At present, there is no multifunctional combustible gas valve unit, and the field of combustible gas valve is still blank. Therefore, it is urgent to invent A combustible gas valve unit with high safety and reliability ensures the safety of the transmission and storage of the combustible gas. Contents of the invention [0003] The present invention is a multifunctional combustible gas valve unit invented to solve the problem of low safety in the transmission and storage of combustible gas, and fills the gap in the field of combustible gas valve unit. [0004] Technical scheme of the present invention is: [0005] Multifunctional combustible gas valve unit, includi...
