Abstract
The invention relates to the technical field of safety valve accessories, in particular to a stainless steel valve. According to the technical scheme, the stainless steel valve comprises a cylindrical valve body and an assembly cylinder, and an external thread is arranged outside the assembly cylinder. The stainless steel valve is characterized in that a hexagonal fastening structure is arranged in the middle of the outer cylinder of the valve body, a valve protection device is arranged in the valve body, and a sealing valve is arranged at the lowermost end of the valve protection device; a spring is arranged on the upper portion of the sealing valve, a sealing enhancement structure is further arranged between the valve protection device and the assembly cylinder, and a guide opening is formed in the center of the lower end of the assembly cylinder. The stainless steel valve has the advantages that it can be ensured that the valve has better sealing performance, and the stainless steel valve is better in safety and more convenient to mount when used.
Description
Technical field
The present invention relates to safe valve fitment technical field, more particularly, to a kind of stainless valve.
Background technology
Relief valve be pressurized equipment (such as：Container, pipeline) on overpressure protection apparatus.When equipment pressure rise reach predetermined
During value, relief valve automatically turns on pressure release, prevents equipment pressure from continuing to raise.When reduced pressure is to setting, relief valve is timely
It is automatically switched off, prevent medium in equipment to run off in a large number.The opening and closing element of relief valve is subject to be in normally off under external force effect, works as equipment
Or the pressure medium in pipeline is when increasing to over setting, by preventing medium in pipeline or equipment to discharge medium outside system
Pressure exceedes specified value.Relief valve belongs to automatic valve class, is mainly used in boiler, on pressure vessels and pipes, and control pressure is not
Exceed setting, important protective effect has been run to personal safety and equipment.
Before carrying out pressure release, inside needs to be in the space of a sealing valve, and the sealing of therefore valve is to valve
The most important requirement of equipment, if the poor sealing of valve will affect the air pressure within pipeline, thus just affect people
Often use.The valve of traditional approach is to be guaranteed by internal sealed valve and valve body (safe valve body) directly contact
Sealing.
Content of the invention
It is an object of the invention to provide a kind of stainless valve, the valve of relief valve is made to have by setting sealing reinforcement structure
There is better seal.
Technical scheme is as follows：
A kind of stainless valve, including cylinder valve door main body and assembling cylinder, the outside of described assembling cylinder is provided with outward
Screw thread it is characterised in that：The outside cylinder centre position of described valve body is provided with hexagonal fastening structure, described valve body
Inside be provided with valve protection device, the bottom of described valve protection device is sealed valve, the top of described sealed valve
It is provided with spring, be additionally provided with sealing reinforcement structure between described valve protection device and described assembling cylinder, under described assembling cylinder
End center is provided with targeting port.
Further, the profile of described sealing reinforcement structure is cylinder, and cross section is L-shaped.
Further, described assembling cylinder lower end is additionally provided with assembly chamfer.
Further, the overall diameter of described valve body is more than the overall diameter of described assembling cylinder.The beneficial effect of the present invention
Really：
Present invention can assure that valve has better seal, safety during use more preferably, is installed more convenient.

Specific embodiment
As shown in Figures 1 to 5, a kind of stainless valve is it is provided that better seal makes stainless valve use
When may provide the user with a safer environment.Stainless valve is additionally provided with fastening structure and some dresses of convenient installation
Join Aided Design, so that installation is more convenient, using more extensive.The stainless valve of the present invention includes cylinder valve door main body 2 and dress
Join cylinder 3, the outside of described assembling cylinder 3 is provided with external screw thread, and external screw thread is used for connecting installation.Described valve body 2 cylindrical
Post centre position is provided with hexagonal fastening structure 1, and hexagonal fastening structure 1 makes convenient during installation, and operability is more
By force, using more convenient.The inside of described valve body 2 is provided with valve protection device 4, realizes gas by valve protection device 4
Pressure exceedes self-relieving purpose during setting value.The bottom of described valve protection device 4 is sealed valve 5, sealed valve 5 with
Stainless valve contacts it is ensured that the sealing of peacetime state.The top of described sealed valve 5 is provided with spring 7, described valve
It is additionally provided with sealing reinforcement structure 6, the setting of valve protection device 4 is preferably protected between door protection device 4 and described assembling cylinder 3
Hinder the sealing of stainless valve, made the sealing effectiveness of stainless valve more preferably, safer.In described assembling cylinder 3 lower end
Heart position is provided with targeting port 8, and targeting port 8 connects inside container or pipeline, links together with air pressure inside, is needing to be let out
During pressure, necessary pressure release is carried out by this targeting port 8.
Preferably, the profile of described sealing reinforcement structure 6 is cylinder, cross section is L-shaped.Cylindrical sealing is strengthened
Structure 6 can be connected tightr, so that sealing between reinforcement structure 6 and assembling cylinder 3 with the inside of cylindrical assembling cylinder 3
Better tightness.The cross section of sealing reinforcement structure 6 is L-shaped, when so may insure that it and sealed valve 5 are engaged more
Step up close, make the overall tightness of stainless valve have more preferable guarantee.
Preferably, described assembling cylinder 3 lower end is additionally provided with assembly chamfer 9, when being assembled, by assembly chamfer 9
Assembly manipulation can be made more smooth, and also avoid when mounted due to scratching the feelings of part when the wedge angle of part leads to assemble
Condition occurs.
Preferably, the overall diameter of described valve body 2 is more than the overall diameter of described assembling cylinder 3, rustless steel can be made
The volume of valve has obtained the control of effect, so that production cost is decreased.
The above is the preferred embodiment of the present invention it is noted that for those skilled in the art
For, on the premise of without departing from principle of the present invention, some improvement can also be made or replace, these improve or replace
Should be regarded as protection scope of the present invention.
