Description
Technical field
This utility model relates to valve field, is a kind of paint high-pressure filteration safety relief valve.
Background technology
Relief valve, also known as " relief valve ", is that the operating pressure according to system can realize automatic open close function, is generally mounted to
Security of system is protected on the equipment of closed system or pipeline.When equipment or manifold pressure exceed relief valve setting pressure, i.e.
Automatically turn on pressure release, it is ensured that equipment and pipeline internal medium pressure, under setting pressure, protect equipment and pipeline, prevent meaning
Outward.Existing relief valve is different according to actual application environment, and its requirement also differs, such as, paint the relief valve of environment under high pressure,
Owing to the characteristic of the medium of paint own is different from general fluid or gas, for the motility of relief valve, adjustability and reliable
Property have a higher requirement, therefore general relief valve is more difficult is suitable for.Existing relief valve is mostly to dispatch from the factory i.e. to set intrinsic pressure
Scope, it is more difficult to flexible, and relief valve is more and without manually regulation and the function of media filtration, causes some operating mode relatively
Difficult applicable.To this end, need to be improved existing relief valve, the relief valve being particularly applied to paint under environment under high pressure is carried out
Improve.
Summary of the invention
For overcoming above-mentioned deficiency, this utility model design one paint high-pressure filteration safety relief valve so that it is solve existing
Similar relief valve restricted application, it is more difficult to meet the technical problem used under paint environment under high pressure.It uses following technical side
Case realizes.
This paint high-pressure filteration safety relief valve includes body portion and filtration fraction, and body portion includes valve rod, valve pocket,
Valve rod slides along valve pocket axial limiting, and when valve rod is axially slided to a wherein positive stop end along valve pocket, the valve of body portion
Opening, when valve rod is axially slided to another positive stop end along valve pocket, the valve closing of body portion, filtration fraction is provided with control oil
The import of the paint flow direction, pressure release refluxing opening, outlet, the valve of body portion is between the import and hydraulic return mouth of filtration fraction
Path in.Described valve rod is moving rotary relative to described valve pocket, and valve rod bar portion is fixed with the pin along valve rod radial protrusion
Body, arranges the linkage block of the location that slides axially along valve pocket in described valve pocket, linkage block one end is provided with convex with what described shank linked
Wheel face, linkage status is: shank along cam surface slide time, band ovable valve stem rotates, and valve rod slides axially along valve pocket；Linkage block is another
One end offsets spring, and spring compression be limited in valve pocket in keep pushing against to linkage block.By above-mentioned by valve body and filtration fraction
In conjunction with, thus realize high pressure paint and filter and pressure release dual-use function；Valve rod in valve body arranges shank, convex along linkage block of shank
Wheel face slides, thus when hand rotation valve rod, valve rod slides axially relative to valve pocket, it is achieved the manual unlocking of valve or pass
Close.
The valve of described body portion, by sealing valve head and valve seat is constituted, seals valve head and is fixed on described valve rod and is positioned at valve pocket
Interior one end, valve seat is fixed on described valve pocket one end, and when sealing valve head and valve seat offset sealing, described valve closing, when close
Envelope valve head and valve seat release when offseting, and described valve is opened；Between described valve rod and described valve pocket, sealing member is set, when described close
When envelope valve head is by the air pressure inside effect of described filtration fraction, seals valve head by gas pressure power transfers to valve rod, and produce
Raw one is become to making valve rod along the active force of valve pocket axially-movable, and this active force is transferred to described linkage block and described bullet by valve rod
Spring, when this active force is more than the active force of described spring, described valve is opened, when this active force is less than the effect of described spring
During power, described valve remains turned-off.By this structure, it is achieved the releasing pressure automatically of valve body.
Described filtration fraction includes filtering glass holder, filtering inner core, filter screen, filter cup gland, filters glass holder one end and filtration
Cup gland is tightly connected, and both are internally formed a filter chamber, and described filter screen is positioned in filter chamber, and described filtration inner core is placed in
