Description
Technical field
The utility model relates to instrument field, specifically a kind of long-range anti-explosion pressure gage.
Background technology
Tensimeter, because it is simple in structure, easy to use and the advantage of energy display-object environmental pressure, is widely used in industry-by-industry.Tensimeter can, because human operational error, external environment variation or internal pressure are abnormal, cause the manometric pressure that bears exceed nominal parameter and blast in the time of work.For support personnel's safety, in prior art, also can adopt some measures to go to strengthen manometric intensity, but to show internal pressure excessive, the gas pressure release of still can gushing from the weaker place of tensimeter, and also the outlet of explosion cannot be directed.Existing tensimeter, bonnet mostly adopts metal shell and bolt to fix, and is all that glass disintegrating slag can cause huge actual bodily harm to observer from apparatus glass direction generation explosion while blasting.
Existing ordinarily manometer directly contacts with measured node, when operating personnel operate and measured node distance, can meet preferably user demand at the tensimeter of common this version of occasion; But at the environment such as chemical industry, UHV (ultra-high voltage), the tensimeter of this kind of version brings great hidden danger to operating personnel's security, even if tensimeter is in comparatively safe environment, if pressure is excessive, also can make the tensimeter accident of blasting, therefore need further improvement.
Utility model content
The purpose of this utility model is to provide a kind of long-range anti-explosion pressure gage that sends alerting signal and can improve operator safety, to solve the problem proposing in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme:
A kind of long-range anti-explosion pressure gage, comprise instrument and betal can, the front end of described betal can is provided with tempered glass, tempered glass embeds inside, betal can edge, described betal can edge is provided with presser feet, between presser feet and tempered glass, be provided with rubber blanket, presser feet is fixed on the edge of betal can by nut, between described instrument and betal can, form hollow sandwich, the rear end of betal can is provided with holder, holder is provided with the spiral duct being communicated with instrument, and the bottom of betal can is provided with supporting seat, and the top of betal can is provided with the disappointing retaining valve and the hummer that are communicated with hollow sandwich.
As further program of the utility model: described presser feet is provided with five, and is evenly distributed on betal can edge.
As further scheme of the utility model: the apparatus glass face in described instrument and tempered glass are in the same side.
Compared with prior art, the beneficial effects of the utility model are: the steric restriction that betal can forms the continuation campaign of apparatus glass disintegrating slag, avoided injuring the accident of human body; Can give the alarm in time sound point out danger signal of hummer, disappointing retaining valve can be accelerated pressure release, slows down the pressure in instrument, further prevents larger explosion accident, and field staff is played a very good protection; By spiral duct, instrument is arranged on from rugged environment in safe environment, ensures the residing Environmental security of instrument, thereby guarantee the Environmental security of field staff in the time reading tensimeter numerical value.

Fig. 2 is the right view of long-range anti-explosion pressure gage.
In figure: 1-betal can; 2-presser feet; 3-nut; 4-tempered glass; The 5-retaining valve that loses heart; 6-hummer; 7-apparatus glass face; 8-holder; 9-instrument; 10-spiral duct; 11-rubber blanket; 12-supporting seat.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1～2, in the utility model embodiment, a kind of long-range anti-explosion pressure gage, comprise instrument 9 and betal can 1, the front end of betal can 1 is provided with tempered glass 4, and the apparatus glass face 7 in instrument 9 is with tempered glass 4 in the same side, and double glazing is for the numerical value in reading displayed instrument; Tempered glass 4 embeds betal can 1 inside, edge, and betal can 1 edge is evenly provided with five presser feets 2, between presser feet 2 and tempered glass 4, is provided with rubber blanket 11, and presser feet 2 is tightly fixed on the edge of betal can 1 by nut 3, avoid the phenomenon that leaks air; Between instrument 9 and betal can 1, forming hollow sandwich, is subnormal ambient in hollow sandwich.
The rear end of betal can 1 is provided with holder 8, and holder 8 is provided with the spiral duct 10 being communicated with instrument 9, and the length of spiral duct 10 is determined according to field condition; The bottom of betal can 1 is provided with supporting seat 12, the lower end of supporting seat 12 is fixed in container or ground surface platform by the fastening such as support or pole, prevent that instrument is because placing and damaged by pressure for a long time, the top of betal can 1 is provided with the disappointing retaining valve 5 and the hummer 6 that are communicated with hollow sandwich, be convenient to give the alarm in time signal, and the effect of pressure release.
When the pressure in instrument 9 excessive, apparatus glass face 7 in instrument 9 is damaged and splits by air pressure, the negative pressure of hollow sandwich becomes high pressure conditions, the steric restriction that betal can 1 and tempered glass 4 form the continuation campaign of apparatus glass disintegrating slag, therefore avoided the accident of injury human body; Certain pressure is born in the space that betal can 1 and tempered glass 4 form simultaneously, pressure in hollow sandwich continues to rise while reaching certain value, first hummer 6 sends and pipes, the sound that gives the alarm, prompting danger signal, in the time that the pressure in hollow sandwich continues to rise, the retaining valve 5 that loses heart starts pressure release, slow down the pressure in instrument, prevent larger explosion accident, field staff is played a very good protection; The length of spiral duct 10 is determined according to on-site actual situations, instrument is arranged on from rugged environment in safe environment, ensures the residing Environmental security of instrument, thereby guarantees the Environmental security of field staff in the time reading tensimeter numerical value.
