Description
Technical field
The utility model relates to a kind of safety valve more particularly to a kind of inner safety-valves.
Background technique
Safety valve is a kind of special equipment for pressure system overpressure protection, is a kind of automatic valve.Work as system pressure
When reaching set-pressure, the fluid of certain load quantity is discharged using the power of medium itself not by any external force for it,
It is more than scheduled safety value to prevent pressure in locking system.When pressure recovery is normal, valve will go again closing with prevent medium after
Afterflow goes out, and there are many type of safety valve, wherein generally requiring Low lift safety valve, opening travel height for marine air
Are as follows:≤0.05d0, for lesser stroke, the reaction speed being turned on or off needs to reach requirement, and when being closed, and needs
Stablize depressed stem and need uniform force in the process, to prevent flap closure uneven, leads to poor sealing.
Utility model content
The utility model provides a kind of inner safety-valve in order to solve problem above.
The technical solution of the utility model is: the safety valve includes flap, gasket, valve body, valve rod, valve seat and branch
The top of safety valve is arranged in frame, the valve body, and the flap is arranged in valve body, and valve body is arranged in the valve seat
Lower part is simultaneously fixed by fixing bolt, and the top of valve seat is arranged in the flap, and the bracket is fixedly connected on valve seat
Lower part, the valve rod are vertically arranged in valve seat, and the valve rod top connects flap, the valve rod upper outside setting
There is a circle gasket, gap is equipped between the valve seat and valve rod, equipped with guide sleeve in the gap, in the valve seat
From top to bottom from small to large, the bracket lower part is connected with spring assembly in portion, and the spring assembly spiral is arranged in valve rod
Outside, and fixed by mounting base, the valve seat is equipped with multiple mounting holes, and the mounting hole extends into valve seat.
The adjusting of the utility model the utility model pressure is simple and easy, and air-tightness is good, increases the structure
Service life, be suitble to promote the use of.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
1 it is flap in figure, 2 be gasket, 3 be valve body, 4 be valve rod, 5 be valve seat, 6 is bracket.
Specific embodiment
