Description
Technical field
The utility model relates to a kind of protective device, particularly relates to a kind of automatic resistance pressure release power gauge stand.
Background technology
Tensimeter is one of special equipments such as boiler, pressure vessel safety attachment commonly used, and pressure vessel is widely used in the production fields such as petrochemical complex, medicine, refrigeration as pressure-bearing class special equipment.The pressure gauge stand is the heavy connection that connects tensimeter and special equipment body, the general cut-in pressure gauge stand on the vertical ground, appropriate location of pressure vessel body, pressure gauge stand top setting pressure table.The pressure gauge stand of using now generally all is a through type; In case damaging, tensimeter comes off; Valve on operating personnel scene of will arriving in the very nick of time and the manual-lock gauge manifold, but some place, operating personnel can't be fast near accident point; Cause the medium in the special equipment under interior pressure effect, to be let out, cause the secondary injury accident by the spray of pressure gauge stand.Wherein, The medium of some pressure vessel institute splendid attire is gas or a liquid gas poisonous, inflammable, explosive, severe corrosive; If this type pressure vessel base ruptures suddenly or because of other reasons loses original sealing (in actual motion, truly having generation) suddenly, will cause overflowing in a large number of hazardous medium, even can't carry out rush repair work at all; Not only cause the waste of resource, also serious pollution environment.
The utility model content
The utility model has overcome deficiency of the prior art, and a kind of reasonable in design is provided, and is quick on the draw, safe and reliable automatic resistance pressure release power gauge stand.
In order to address the above problem, the utility model adopts following technical scheme:
Automatically resistance pressure release power gauge stand comprises the pedestal, sealing float and the pressure spring that are made up of upper shell and lower house, and pedestal is penetrating up and down, and the pedestal middle part is provided with centre chamber, is provided with the sealing float in the centre chamber; The centre chamber top is provided with out runner, and the bottom is provided with the influent stream road, goes out the seat groove that the runner top is provided with the setting pressure table; The sealing float is three stage structure, the tapered structure in top, stepped column construction below the pyramidal structure; Go out the external diameter of the internal diameter of runner less than sealing float cone the widest part; The sealing float outside is with pressure spring, and the pressure spring bottom is against the step place of sealing float ladder cylinder, and the top is fixed on centre chamber's end face;
The outside stepped column construction of upper shell and lower house, cooperatively interacting connects as one; The upper shell bottom is provided with externally threaded column-shaped barrel, and lower house top is provided with the cylindrical cavity of internal thread, and through being threaded and being surrounded as centre chamber in the inboard, the outside, lower house bottom is provided with screw thread between upper shell and the lower house.
Place, described lower house upper edge is provided with the annular seal groove, and the O RunddichtringO is installed in the seal groove, seals through the O RunddichtringO between upper shell and the lower house.
Described sealing float adopts solid construction.
Compared with prior art, the beneficial effect of the utility model is:
1, is provided with the sealing float in the utility model pressure gauge stand; In case damaging, tensimeter comes off or gauge stand pressure at both sides when strengthening unusually; Sealing float in the gauge stand will issue lively work in interior pressure effect, and the outlet of confining pressure gauge stand prevents that poisonous and hazardous medium from leaking automatically; Not only avoid environment contaminated, also effectively prevented burning or explosion accident.
2, the pedestal of the utility model gauge stand adopts the split-type structural design, and when the sealing float damaged, the convenient taking-up changed, and need not the integral replacing gauge stand, effectively reduced maintenance cost.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Automatically resistance pressure release power gauge stand is as shown in Figure 1, comprises the pedestal, pressure spring 3, the sealing float 4 that are made up of upper shell 1 and lower house 5; Pedestal is penetrating up and down; The pedestal middle part is provided with centre chamber 8, is provided with sealing float 4 in the centre chamber 8, and sealing float 4 adopts solid construction; Centre chamber 8 tops are provided with out runner 7, and the bottom is provided with influent stream road 9, go out the seat groove 6 that runner 7 tops are provided with the setting pressure table; Sealing float 4 is three stage structure, the tapered structure in top, stepped column construction below the pyramidal structure; Go out the external diameter of the internal diameter of runner 7 less than sealing float 4 cone the widest part; Sealing float 4 outsides are with pressure spring 3, and pressure spring 3 bottoms are against the step place of sealing float 4 ladder cylinders, and the top is fixed on centre chamber's 8 end faces.
The outside stepped column construction of upper shell 1 and lower house 5, cooperatively interacting connects as one.Upper shell 1 bottom is provided with externally threaded column-shaped barrel; Lower house 5 tops are provided with the cylindrical cavity of internal thread; Through being threaded and being surrounded as centre chamber 8 in the inboard, the outside, lower house 5 bottoms is provided with screw thread, is connected with pressure vessel between upper shell 1 and the lower house 5; Be convenient to processing, install, need not transform existing equipment and can install.Place, lower house 5 upper edges is provided with the annular seal groove, and O RunddichtringO 2 is installed in the seal groove, seals through O RunddichtringO 2 between upper shell 1 and the lower house 5.
When pressure vessel normally moves, influent stream road 9 successively through centre chamber 8, go out runner 7 and the tensimeter installed on the present groove 6 communicates, thereby can reflect the pressure of this pressure vessel interior media truly.When the pressure gauge stand owing to reasons such as fracture have lost original sealing suddenly; The pressure-bearing medium that will cause internal tank is along going out runner 7 ejections; The inside and outside pressure reduction of container makes the automatic shutoff of sealing float 4 rapid liftings go out runner 7; Stop hazardous medium longshore current road to leak in a large number, at this moment can carry out operations such as accident is speedily carried out rescue work, leak stopping.Wait to recover normal after, centre chamber 8 forms air-tight state again, because of the micro-seepage of medium makes the air pressure balance around the sealing float 4, then seals float 4 at the double action of pressure spring 3 and deadweight thereof seat next time, recovers manometric pressure measurement function.
