Abstract
The utility model relates a metrological measurement technical field, in particular relates to a pressure gauge measuring the pressure, consists of a base and a pipe connector, and is characterized in that a diaphragm is arranged inside the base. The diaphragm is communicated with a transparent pressure gauge gas cup arranged on the base. The utility model has the advantages of a good anti-vibration performance, a simple structure and a long service life without any buffering device equipped.
Description
Technical field
The utility model relates to a kind of metrological testing technology field, especially relates to a kind of tensimeter of gaging pressure.
Background technology
Existing tensimeter mainly by base, in base, be provided with gear train, gear train concatenation pointer, pointer is arranged on the index dial, in use, because the fluctuation of liquid or gaseous tension, the no small swing of amplitude can appear in gauge hand, causes reading to be difficult to accurately, and if release too fast, gauge hand returns zero too fast, pointer is broken or the reduction of gauge hand spring precision; And at present for addressing the above problem, often adopt shockproof tensimeter, this shockproof tensimeter is actually and adds damping oil in ordinarily manometer, and it is too fast to make gauge hand be subjected to damping action to be unlikely to return, but when this kind buffering pointer return returns zero, also increased the damping that pointer rises, pointer is risen slowly, pressure shown in the pointer is in a long time less than actual pressure, read untrue consequently, efficient is low, and the manometric cost height of this kind, and price is expensive.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and the novel pressure table simple in structure that a kind of anti-seismic performance is good, need not install any snubber assembly additional is provided.
The utility model is implemented in the following way:
A kind of novel pressure table comprises base and pipe adapter, it is characterized in that: be provided with a barrier film in this base, barrier film communicates with one base-mounted one transparent tensimeter gas cup;
Described tensimeter gas cup is with scale at a moment outward;
Also be provided with a temperature scale on the described base;
Also be provided with a pressure warning unit on the described base;
Described barrier film is material such as flexible plastic or the rubber that freely deformable has certain toughness.
The utility model has following effect:
The novel pressure table that the utility model provides, not existing manometric mechanical driving device is directly used liquid, show force value by liquid level, thereby do not have mechanical loss, thereby have anti-seismic performance, accuracy of reading, long service life is particularly useful for the big occasion of working environment vibration and uses.This use is novel not to have the complicated mechanical gearing, simple in structure, and cost, cost are low.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Embodiment
A kind of novel pressure table comprises base 1 and pipe adapter 5, and as shown in Figure 1: be provided with a barrier film 2 in this base 1, the transparent tensimeter gas cup 3 that barrier film 2 and is contained on the base 1 communicates.Line can directly graduate on tensimeter gas cup 3, also can outside tensimeter gas cup 3, overlap an index dial 4 again, in this class tensimeter in order to improve the accuracy of force value reading, special in accurate type phenotype, installed the instant reading that temperature scale 6 and index dial 4 come the calibrating (base measuring) pressure table additional, can under different working temperatures, obtain the accurate pressure value like this, avoid causing force value inaccurate because of the variation of working temperature.
The principle that tensimeter is inversely proportional to according to the pressure and the volume of gas, during use, pipe adapter 5 is contained in the position of wanting detected pressures, communicate with the chamber of survey gas or liquid in the base 1, the gas of pressurized or liquid enter in the base 1 like this, its pressure promotes barrier film 2, because material such as flexible plastic or rubber making that barrier film 2 is freely deformables has certain toughness, thereby its pressurized post shrinkage, thereby the liquid in it is risen, show by tensimeter gas cup 3, read actual force value from index dial 4.Because temperature variation can be influential to gas in the tensimeter or liquid, thereby also be provided with a temperature scale 6 on base 1, adjusts the orientation of tensimeter index dial 4.Also be provided with a pressure warning unit 7 on the base 1, can be designed to low pressure alarming or alarm for high voltage as required.
This tensimeter can also be made with materials such as plastics and PVC entirely, can directly detect the pressure of severe corrosive gas or liquid.
Claims (5)
