Embodiment
The preferred embodiments of the present invention are illustrated below in conjunction with accompanying drawing, it will be appreciated that described herein preferred real
Apply example to be merely to illustrate and explain the present invention, be not intended to limit the present invention.
Embodiment 1
As shown in Figure 1-2, the invention provides a kind of safety-type fuel gas pressure-regulating box, including casing 1, the bottom of casing 1 to be provided with
Import header 2, the top of import header 2 are provided with inlet ball valve 3, and the top of inlet ball valve 3 is provided with flange 4, set on flange 4
It is equipped with FlexbleJoint 5, the top of flange 4 is provided with filter 6, and the side of filter 6 is provided with first flowmeter 7, and first
The side of flowmeter 7 is provided with second flowmeter 8, and the bottom of second flowmeter 8 is provided with superpressure diverging valve 9, second flowmeter 8
Side be provided with pressure regulator 10, the bottom of pressure regulator 10 is provided with limiting pressure closing valve 11, and the side of pressure regulator 10 is provided with
Three flowmeters 12.
The side of casing 1 is provided with heat sink 13, and the bottom of heat sink 13 is provided with fire extinguisher 14, casing 1 it is another
