Description
Technical field
The present invention relates to pressure gauge instruction device.
Background technology
Pressure gauge is commonly used a kind of pressure-indication means in many industrial production environments, its security to production
Serve very important effect.According to the regulation of some industries, instruction operating pressure should be drawn on manometric dial plate
Or the instruction line of warning pressure, and instruction line is typically only capable to spray picture with coloured (as red) paint or pastel, or in pressure
Red line scale paper patch is pasted on dial plate to replace spraying picture.But because pressure dial plate is usually glass material, it is to paint and ink
Adhesive force effect is poor, and pressure gauge be generally it is outdoor use, paint, ink or paper patch be all easy to come off after exposing to the sun and rain,
So that the effective time for indicating is short, instruction line is caused to be difficult observation.Meanwhile, if the circumferential position of pressure dial plate is moved,
Instruction line just loses the mark action of correct scale, causes potential safety hazard.Also, due to the scale of pressure dial plate tripping power table
Disk has certain spacing, it is necessary to sight line could read perpendicular to pressure gauge front when checking the corresponding relation of instruction line and scale
Exact value, this also result in the inconvenient problem of observation.
The content of the invention
In view of the shortcomings of the prior art, the invention provides a kind of pressure gauge instruction device, can be according to different occasions
Need that the position of different instructions is easily adjusted and set, and failure etc. will not be indicated to ask caused by natural cause
Topic.
Pressure gauge instruction device of the invention, the body with annular, is provided with what is be connected with body along body is axially extending
Finger slips portion, finger slips are provided with guide-track groove in portion, located at the thread cap that the pointer of body radially inner side passes through outer body
It is connected with the guide-track groove.The body of annular is used to be placed on manometric dial plate radial outside, and pointer can be in guide rail
Slided in groove, by thread cap fastening and guide-track groove after being alignd with specified pressure gauge scale.By the instruction device to pressure
The specified pressure of power table is indicated, not only long service life, will not be fuzzy or the problems such as fail because being indicated caused by open-air atmosphere,
And can be according to the position that pointer in instruction device is adjusted the need for different occasions, with extensive versatility.Simultaneously as
The finger slips portion of instruction device is axially protruded in instruction device body, therefore can be to a certain degree in open-air atmosphere
Upper rain cover, dew etc., make the corresponding pressure matrix section of pointer apparent, it is easy to observe.
Further, in order to adapt to the pressure gauge of various different sizes, size, being provided with body can be by fastening
The connecting portion of part connection.Directly connected by fastener after so instruction device can be nested with the pressure gauge of arbitrary size
Connecting portion on body is fixed.The fastener is preferably the tight of the other forms such as threaded fastener, or buckle
Firmware.In the case where pressure table size is same, it would however also be possible to employ the instruction device of closed annular, directly it is placed on manometric
Outside dial plate.
According to specified pressure scopes such as operating pressure, the warning pressures for generally using occasion, preferably by the guide-track groove
Length be set at least to make pointer to be slided in the range of 90 ° of central angle along guide-track groove.So will not both make the length of guide-track groove
Spend length and cause unnecessary waste, it is also possible to fully meet the various instruction needs of different occasions.
Preferably, the surface of pointer is coated with ight reflectorised paint, such as red ight reflectorised paint etc., so can be conveniently
Observed at night.
Pressure gauge instruction device of the invention, simple structure is easy for installation, and can be according to right the need for different occasions
The position that difference is indicated easily is adjusted and is set, with good versatility, and long service life, will not be because of nature
Reason causes the problems such as indicating fuzzy or failure.
Specific embodiment with reference to embodiments, is described in further detail again to the above of the invention.
But this scope for being interpreted as above-mentioned theme of the invention should not be only limitted to following example.Think above-mentioned technology of the invention is not departed from
In the case of thinking, according to various replacements or change that ordinary skill knowledge and customary means are made, this hair all should be included in
In bright scope.
Brief description of the drawings
Fig. 1 is the dimensional structure diagram of pressure gauge instruction device flat condition of the present invention.
Fig. 2 is the A of Fig. 1 to schematic diagram.
Specific embodiment
Pressure gauge instruction device of the invention as depicted in figs. 1 and 2, the body 1 with annular, the body 1 can be adopted
Constituted with the metal material with antirust, Corrosion Protection.Along the axially extending finger slips that are connected with body 1 of being provided with of body 1
Portion 2, is provided with guide-track groove 3 in finger slips portion 2.The finger of red ight reflectorised paint is coated with located at the surface of the radially inner side of body 1
Pin 5 is connected by the thread cap 4 in the outside of body 1 with the guide-track groove 3, and pointer 5 can be along guide-track groove 3 in central angle
Slided in the range of 90 °, and by the fastening of thread cap 4 and guide-track groove 3.Body 1 is provided with the fastening that can coordinate by screw thread
The connecting portion 6 of the connection of part 7, enables body 1 to be placed on outside the pressure dial plate of various different sizes, size.
