Abstract
The invention relates to a pressure gauge protection device. The pressure gauge protection device is used in a slurry pressure measuring device which is used for slurry filling and consists of a pressure gauge (1), an upper connector (2), an oil conduit (3), an oil chamber (4), an elastic diaphragm (5), a slurry storage chamber (6), a sealing gasket (7), a compression bolt (8), a slurry guide pipeline (9) and a lower connector (10). The pressure gauge protection device is characterized by that the protection device is an arc-shaped metal plate (11); and the arc-shaped metal plate (11) is provide with oil holes (12) and is arranged in the oil chamber (4) above the elastic diaphragm (5). The pressure gauge protection device is manufactured according to the pressure deformation principle and is simple in structure, not easy to damage in the using process and safe and reliable in performance, and damages to the pressure gauge caused by sudden pressure increase due to pipeline blockage, a water hammer and other factors is completely eliminated.
Description
Technical field
The invention belongs to surveying instrument technical field, relate in particular to a kind of tensimeter protective device.
Background technology
Along with developing rapidly of economy, in each field, grouting process is more and more used, and in work progress, the tensimeter damage of measuring slurries pressure is considerable simultaneously.This not only brings no small economic loss, the more important thing is and affects normal construction, even causes some accidents.In order to guarantee to measure accurately, barrier film used is, the film film that has been out of shape large by elasticity generally.But in line clogging, suppress under the instantaneous large pressure such as pump and easily break, slurries enter into manometric sensor and cause malfunctioning infringement.For this problem, the present invention can well solve the problem of tensimeter frequent breakage.
Summary of the invention
The object of the invention is to design a kind of reliable, practical tensimeter protective device.Realizing the technical scheme that object of the present invention takes is: this protective device for by tensimeter, upper binding head, oil guide pipe, grease chamber, elastic diaphragm, storage slurry chamber, sealing gasket, hold-down bolt, lead the grouting measurement slurries pressure apparatus that slurry pipeline and lower union joint forms.This protective device is an arc sheetmetal, and arc sheetmetal is provided with oil-through hole, is arranged in the grease chamber of elastic diaphragm top.
whenslurries pressure promotes elastic diaphragm, make elastic diaphragm produce deformation, indicate grouting pressure through hydraulic oil pressure transmission to tensimeter, in the time that pressure is eliminated, the own elasticity of oil pressure and elastic diaphragm is rebounded elastic diaphragm automatically, protective device is positioned at elastic diaphragm top, for arcuate structure, inner wall smooth, under pressure, pressure transmission oil can be freely by the multiple oil-through hole conducting pressures on protective device, deformation exceedes elastic diaphragm to a certain degree, can be stoped its further deformation by protective device, prevents that elastic diaphragm from breaking.If want to adjust controlled pressure size, only need to change the radian of arc sheetmetal, change the volume of protective device.
The present invention is according to pressure deformation principle, simple in structure, and in use not fragile, performance safety is reliable, has got rid of completely because of the infringement that increasing causes tensimeter suddenly of the reason such as line clogging, water hammer pressure.Guarantee tensimeter safety, normally, effectively work.Thereby the sensing element of having avoided ordinarily manometer to cause grease chamber's membrane ruptures, slurries to be pressed in tensimeter because slurries pressure is excessive causes the problem that tensimeter is malfunctioning, scrap.
Accompanying drawing explanation
fig. 1 is the present invention's structural representation in measurement slurries pressure apparatus;
Fig. 2 is floor map of the present invention.
In figure, 1, tensimeter, 2, upper binding head, 3, oil guide pipe, 4, grease chamber, 5, elastic diaphragm, 6, storage slurry chamber, 7, sealing gasket, 8, hold-down bolt, 9, lead slurry pipeline, 10, lower union joint, 11, arc sheetmetal, 12, oil-through hole, 13, bolt fixed orifice.
Specific embodiments
With reference to accompanying drawing, this protective device for by tensimeter 1, upper binding head 2, oil guide pipe 3, grease chamber 4, elastic diaphragm 5, storage slurry chamber 6, sealing gasket 7, hold-down bolt 8, lead grouting that slurry pipeline 9 and lower union joint 10 form with measuring slurries pressure apparatus.This protective device is an arc sheetmetal 11, and arc sheetmetal 11 is provided with oil-through hole 12, is arranged in the grease chamber 4 of elastic diaphragm 5 tops.Said arc sheetmetal 11 is provided with bolt fixed orifice 13, is convenient to be fixed in grease chamber 4.
Concrete use procedure: first in grease chamber 4, fill hydraulic oil, according to accompanying drawing, device assembles is good.Specific works process is: slurries are pressed into storage slurry chamber 6 through leading slurry pipeline 9, slurries promote elastic diaphragm 5 and produce deformation under pressure, hydraulic oil in grease chamber 4, by the oil-through hole 12 on arc sheetmetal 11, enters in the pressure transducer in tensimeter, sensor indication current pressure.When occurring suppressing pressure that the phenomenon such as pump, line clogging produces when excessive, elastic diaphragm 5 produces deformation meeting and is subject to the restriction of arc sheetmetal 11, stops it to be further out of shape, and prevents that elastic diaphragm 5 from breaking.Guarantee that measurement result is accurate.
Claims (2)
1. a tensimeter protective device, for by tensimeter (1), upper binding head (2), oil guide pipe (3), grease chamber (4), elastic diaphragm (5), storage slurry chamber (6), sealing gasket (7), hold-down bolt (8), lead the grouting measurement slurries pressure apparatus that slurry pipeline (9) and lower union joint (10) forms; It is characterized in that: this protective device is an arc sheetmetal (11), and arc sheetmetal (11) is provided with oil-through hole (12), be arranged in the grease chamber (4) of elastic diaphragm (5) top.
2. according to the said tensimeter protective device of claim 1, it is characterized in that said arc sheetmetal (11) is provided with bolt fixed orifice (13), is convenient to be fixed in grease chamber (4).
