Abstract
The utility model relates to a diaphragm type current limiting shock absorber for a shock resistant pressure instrument. The shock absorber comprises a pressure instrument and an instrument connector, wherein the upper end and the lower end of the instrument connector are connected with the pressure instrument and an upper diaphragm respectively; center lines of the instrument connector, the upper diaphragm and a lower diaphragm are provided with concentric through holes; the middle end part of the through hole of the instrument connector is provided with a current limiter, which has both ends of the center part provided with two taper-shaped current limiting blocks horizontally arranged on the upper bottom of the center hole; and a rubber diaphragm arranged in a cavity of the lower diaphragm divides the cavity into two cavities of an upper cavity of diaphragm and a lower cavity of diaphragm. The shock absorber of the utility model has the advantages of simple structure, reasonable design, low cost, good separation and shock resistant effects for testing medium, good sealing and no leakage, no influence on the pressure correction, accurate indicating value, anti-clogging and long measurement and application service life. The shock absorber can be widely applied to the pressure measurement of media containing solid particles or thick and easily clogged fluid, and places where the shock is quite sharp.
Description
Technical field
The utility model relates to a kind of antidetonation pressure instrumentation, relates in particular to the pressure instrumentation that does not stop up, can measure liquid gas pulsation pressure.
Background technology
At present, the instrument of general measure liquid gaseous tension has multiple, but majority antidetonation not, the indicator amplitude of fluctuation is big, and parts are fragile, and the life-span is short, and use more antidetonation pressure instrumentation is oil-filled table in the watchcase, and its convection cell shock-proof effect is not good, easy-to-leak liquid, easily obstruction.
Summary of the invention
The purpose of this utility model is to overcome the weak point that exists in the above-mentioned technology, provides a kind of simple in structure, reasonable in design, manufacturing assembling and setting convenience, the good and nonclogging antidetonation pressure instrumentation of the anti seismic efficiency shatter-proof device of diaphragm type current limliting.
In order to achieve the above object, the technical solution adopted in the utility model is: comprise pressure instrumentation, meter connector, the meter connector upper and lower end is connected with last diaphragm body with pressure instrumentation respectively, the center line position of meter connector, last diaphragm body and lower diaphragm plate body has concentric through hole, the current limliting body is equipped with at the through hole middle-end position of meter connector, 2 seats are housed at two ends, current limliting body centre to crouch and becomes the taper current limliting stifled in the center pit upper bottom portion, in the chamber of lower diaphragm plate body diaphragm of rubber is arranged, two chambeies will be divided into, barrier film upper chamber and barrier film lower chambers in the cavity.
The utility model has the advantages that:
Simple in structure, reasonable in design, cost is low, and measured medium is had good isolation and anti seismic efficiency, good seal is not revealed, can be not influential to pressure calibration, indicating value is accurate, anti-clogging, it is long to measure application life.The utility model can be widely used in medium solid particle, the susceptible to plugging fluid of sticky state, also can be used on the relatively fiercer occasion gaging pressure of vibrations.
Description of drawings
Fig. 1 is the utility model structural representation;
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
As shown in Figure 1, the utility model is to comprise pressure instrumentation 9, meter connector 8, meter connector 8 upper and lower ends are connected with last diaphragm body 3 with pressure instrumentation 9 respectively, the center line position of meter connector 8, last diaphragm body 3 and lower diaphragm plate body 1 has concentric through hole, current limliting body 6 is equipped with at the through hole middle-end position of meter connector 8,2 seats are housed at two ends, current limliting body 6 centre to crouch and becomes taper current limliting stifled 4 in the center pit upper bottom portion, diaphragm of rubber 2 is arranged in the chamber of lower diaphragm plate body 1, two chambeies will be divided into, barrier film upper chamber 10 and barrier film lower chambers 11 in the cavity.
Pressure instrumentation meter connector 8 ends have sealed aluminum pad 5 meter connector hole inner ends that sealing gasket 7 is housed.
Described diaphragm of rubber 2 is shaped as down and is recessed into bowl-shapely, and the upper edge is the annular of circular arc projection up and down.
The fluid media (medium) of the utility model in equipment or pipeline, enter pressure instrumentation lower diaphragm plate body oil-in, pressure act on barrier film below, move on the barrier film, the fluid that barrier film upper chamber is full of is mobile toward the bourdon tube interior (or pressure transmission chamber) of pressure instrumentation, when blocking up, make the surge pressure that passed play cushioning effect by current limliting.Acted on bourdon tube by the pressure after the damping, make it most advanced and sophisticated distortion, by pull bar, elevating arc, indicate the pressure indicating value that swing reduces greatly by pointer at last again.
The utility model, can be widely used in solid particle is arranged in the fluid media (medium), the susceptible to plugging fluid of sticky state, also can be used on the relatively fierce occasion gaging pressure of vibrations.As: measuring pressure on the equipment installations such as pumping plant outlet, hydraulic machinery, petrochemical industry, hydrocarbon transfer system, Control of Power Plant panel board.
The antidetonation pressure instrumentation that the utility model is formed, can reach tens of times of ordinarily manometer serviceable life, has good economic benefit and social benefit.
