Mouthful.
Specific embodiment
Referring to attached drawing, the pressure-indication means of the application contain protection end cap 1, screw shell 2, instruction core bar 3, spring
4, the upper end outside of seal cartridge 6, limiting bush 7, the screw shell 2 is equipped with external screw thread, connect with protection end cap 1, screw thread
2 lower end of sleeve is equipped with external screw thread, is tightly connected with the pressure acquisition mouth 13 of pressure piping, is a wall surface light in screw shell 2
The upper diameter of sliding three-level stepped hole 10, stepped hole 10 is maximum, and middle part is taken second place, and lower end is minimum, and the top of stepped hole 10 is used for
Seal cartridge 6 and limiting bush 7 are connected, the inside of seal cartridge 6 is sealed by sealing ring and instruction core bar 3, seal cartridge 6
Outside sealed by another sealing ring 5 and screw shell inner wall, the instruction core bar 3 is embedded in the step of screw shell 2
In hole 10, the middle part of instruction core bar 3 is equipped with upper and lower two stopping steps, upper stopping step 8 and lower stopping step 9, two stop
The distance between step is less than the height in screw shell middle bench hole, and spring is equipped in the middle part of the stepped hole 10 of screw shell 2,
The spring is socketed on instruction core bar, indicates that the lower stopping step of core bar can push the spring, the top of instruction core bar 3 passes through
The centre bore of seal cartridge 6 and limiting bush 7, limiting bush implement limit to the upper stopping step of instruction core bar, indicate core bar
3 upper end is equipped with pressure indicateing arm 12, the lower part of the lower part insertion stepped hole 10 of instruction core bar 3, for the fortune for indicating core bar
The effect of its positioning and guiding is moved, the longitudinal center of instruction core bar 3 is the blind hole of a lower ending opening, the lower ending opening connection of the blind hole
10 lower end of stepped hole of screw shell 2, the umbo of the protection end cap 1, is equipped with transparent observation at umbo
Window 11.
In implementation, the pressure indicateing arm on instruction core bar top is three instruction block groups by green, orange, red three kinds of color markings
At.Normal, the placed in the middle orange instruction block representative pressure decline of the green instruction block representative pressure of lower section, the red instruction block at top
Representative pressure is too low.
This pressure-indication means need to be installed under equipment pressure release state, when installation, need to select one and equipment pressure
The matched pressure-indication means of power are tightly connected, installation by matched pressure-indication means and using the pressure acquisition mouth of equipment
Pressurising is carried out to equipment after the completion.The blind hole of instruction core bar lower ending opening is acted on using the pressure of equipment, pushes instruction core bar
It moves up, the pressure indicateing arm for indicating core bar top is made to be moved to the observation window at protection end cap, maintenance personnel passes through observation
The color of indicateing arm obtains the pressure state in equipment in window.When instruction is designated as green in observation window, indicate to use equipment
Interior pressure is good；When instruction is designated as orange in observation window, indicates using pressure reduction in equipment but do not influence to work normally；When
When instruction is designated as red in observation window, indicates that requirement has been not achieved using hypotony in equipment, need pressurising immediately.
The pressure of equipment pressure acquisition mouth is by indicating that core bar inner hole is connected to screw shell inner cavity, when equipment pressure is enough
When, which generates thrust and pushes instruction core bar against the force of the spring, and compressed spring moves up the upper stop platform of instruction core bar
Limit of the rank 8 by limiting bush 7 indicate stopping step upper surface and limiting bush lower end face contact on core bar and limit, this
When, the green instruction block on instruction core bar top reaches at the peep hole for protecting the side of end cap.Therefore work as from protection end cap peep hole
Green instruction block is seen at place, illustrates that the pressure in equipment is normal enough.
When the pressure acquisition mouth pressure reduction of equipment but still when can guarantee equipment use demand, instruction core bar is because be subject to
Thrust decline, and then moved down from upper limit position along instruction core bar axis, so that orange instruction block is dropped to the sight of protection end cap
When examining at hole, therefore work as from protection end cap peep hole it can be seen that orange instruction block, illustrates that the pressure in equipment has loss, but not
To the threshold pression of equipment normal use.Maintenance personnel should be reminded to supplement pressure at this time.
When the pressure acquisition mouth pressure of equipment drops to the threshold pression of equipment normal use, instruction core bar along axis to
Under be moved to lower position.The second level platform of stepped hole 10 in 9 lower surface of lower stopping step and thread bush of core bar is indicated at this time
Rank end face contacts and limits, at the peep hole for the side that the red instruction block on instruction core bar top reaches shell.Therefore work as from shell
It can be clearly visible red instruction block at the peep hole of side, illustrate that pressure in equipment has reached the lower pressure limiting of equipment normal use
Power.Maintenance personnel is alerted at this time, it is necessary to be stopped using equipment and be supplemented pressure.
This pressure-indication means realizes the qualitative display of machinery of pressure using Principle of Mechanical Designing, adapts to high/low temperature, vibration
The severe operating environment such as dynamic, sandstone, salt fog and high-intensity magnetic field, instruction is reliable, and failure rate indicates that reducing makes well below meters
Use maintenance cost.
This pressure-indication means structure is simple, and each External Shape and structure are conventional, easily manufactures.Each part material can be selected normal
Rule easily buying material, cost is lower than meters.And structural volume is small, the pressure that can meet in most small space shows demand.
This pressure-indication means intuitively highlights, and meets the maintenance needs of ground maintenance personnel.
