Specific embodiment
Middle valve body by bolt fastening in upper valve body and lower valve body, in valve body excircle orientation, by middle valve body upper and lower side
The O-ring in face seals；Sealing ring is clamping by lower platen, top board, is tightened on the upside of shaft, and strainer is inlaid in shaft outlet counterbore
It is interior, it is fastened by strainer plug screw；One, spring plug is in shaft lever hole, and other end is in middle valve body counterbore；Shaft lower end screws work
Plug, is installed in the plunger shaft of middle valve body；Middle valve body machined plunger shaft, liner plate pilot hole, pressurised driving mouth, pressurization closing
Mouthful；Liner plate plug is sealed by O-ring, is locked using fastening screw, dnockout core is fixed on upper valve body by loop nut in middle valve body upper end
Right side, sealing screw are mounted on middle valve body bottom righthand side；Usually spring push seal ring assembly and valve seal face contact seal；Disappear
Anti- water source reaches and seals at seal ring assembly, unclamp loop nut, drain by the annular space between upper and lower valve body and middle valve body
The pneumatosis in intracavitary portion then screws loop nut；When spurting: fire water supply enters piston upper chamber by pressurised driving mouth and is pressurized, close
Ring assemblies are moved down by piston effect power, open water outlet, and the water flow of piston cavity of resorption is released by shaft damping port；When closing,
1. decompression is closed: the hydraulic pressure for releasing piston upper chamber is let out, under the collective effect of piston cavity of resorption hydraulic pressure and spring thrust, sealing ring group
Part moves up closing sealing；2. pressurization is closed: the hydraulic pressure of venting piston upper chamber, and fire water supply is closed into mouth by pressurization and is led to
Piston cavity of resorption, seal ring assembly moves up closing sealing under the collective effect of the upward active force of piston and spring thrust, real
Decompression/pressurization closing function is showed；Novel its technical problem of solution of the present invention is adopted the technical scheme that: devising loop spiral shell
Female, dnockout core structure, the left end of dnockout core are hemispherical, and middle section outer circle is the locking shaft shoulder, and middle section is followed successively by O-ring slot, radial direction to the left
Venthole, center are axial exhaust duct, and radial venthole connects with axial exhaust duct, and right side is straight spiral shell outside M14 × 1.5
Line；Loop nut is unclamped, the pneumatosis of body cavity is discharged by radial venthole, the axial centre vent of dnockout core, reduces valve
Air-flow concussion of the door in unlatching, closing process；It is antifreeze to valve chamber inflation in winter, water level in valve is depressed under permafrost haorizon,
Deluge alarm valve is not required to setting electric heating or steam-heated special-purpose thermal insulation case, simplifies the mating and maintenance management at scene；Axis
The lower hole of bar is spring counterbore, the outer straight thread of lower section Excircle machining to assemble piston, in upper hole be that Φ 3mm is damped
Mouthful, upper hole is strainer counterbore, strainer plug screw threaded hole, the upper section Excircle machining shaft shoulder, outer straight thread to assemble lower platen,
Top board, the effect of strainer avoid shaft damping port from blocking, are also prevented from impurity and enter piston cavity of resorption, it is ensured that piston is run flexible
Property；When unlatching, the water flow of piston cavity of resorption is slowly released by shaft damping port, and seal ring assembly slowly moves down, and reduces water flow pair
The impact vibration of pipe network；When decompression is closed, piston upper chamber is by the rapid pressure release of pressurised driving mouth, and cavity pressure does not reduce under piston,
Under piston under the collective effect of cavity pressure and spring, closing is moved up, due to the effect of shaft damping port, piston is to moving up
Dynamic is also slowly, to reduce closing water hammer effect；The annular space section between middle valve body and lower valve body, the section is arranged in pressure tappings (e)
Overflow section is shunk, and hydraulic pressure is maximum, is conducive to driving piston；The present invention is novel to be provided simultaneously with decompression/pressurization closing function, and decompression is closed
Closed operation is simple, and pressurization, which is closed, belongs to positive closing, meets the application requirement that deluge alarm valve protects the high occasion of tens of rice, i.e.,
Make outlet there are tens of meters of hydrostatic head, this valve, which also reliably can promptly be held, is pressed in line closing；Using plane sealing structure, drop
The low concentricity machining accuracy and assembly difficulty of seal ring assembly.
