Abstract
The utility model relates to a vibration absorbing joints of general pressure meter, comprising a joint (1), a filtration (3), a circlip (2), a center vent damping segment (4), a by-pass damping segment (5), sealing gasket (7) and an O-shaped rubber ring. The joint takes advantage of increasing hydraulic damping components to establish a buffer zone between the pressure system under test and the manometer in order to diminish the direct influence coming from the hydraulic vibration and hydraulic impact.
Description
The utility model is a kind of pressure tapping that is used to connect ordinarily manometer and tested pressure piping.
Existing pipe spring formula tensimeter, when being shaken with higher frequency by measuring pressure or meeting hydraulic shock, table
Sharply swing brings error to measurement, and damages the tensimeter parts easily.Use anti-shock pressure meter or special-purpose accumulation of energy shock attenuation device is installed in the bigger hydraulic circuit of vibrations, all because of expensive bigger, used installing space is bigger, causes to use to be restricted.
The purpose of this utility model is to provide a kind of pressure tapping with damping shock absorption effect for ordinarily manometer.It can make pressure tapping have the vibrations that hinder hydraulic circuit and directly enter manometric effect by increase the hydraulic damping parts on the usual pressure meter connector, reduces manometric pendulum shake.
Order of the present utility model ground can reach by following measure: the liquid in the hydraulic circuit by filtering bodies (3), duct (14), in the by-pass port (12) that enters last layer bypass damping fin of central through hole (13), helicla flute (16), ring groove (17) on the logical damping fin, after again through ring groove, helicla flute arrives central blind hole (11), so repeatedly, arrive the center pit (10) of sealing gasket (7), enter tensimeter then.
Description of drawings
The drawing of accompanying drawing is described as follows:
Accompanying drawing 1 is the shock-absorbing connection structural representation.
Accompanying drawing 2 is distressed structure synoptic diagram of accompanying drawing 1.
From accompanying drawing 1 as can be seen, the external thread (15) on the fittings body (1) is connected with tested pressure piping, and internal thread (9) is connected with connecting thread (8) on the tensimeter.The lower plane of screw thread (8) with sealing gasket (7), bypass damping fin (5) and in logical damping fin (4) be pressed on the lower plane of fittings body (1) inner chamber, form butt-end packing by snap-in force between each sheet.Seal by zero type cushion rubber (6) between sealing gasket (7) and the fittings body.This kind structure need not be dismantled damping fin when the cleaning and filtering body.
Concrete enforcement: shock-absorbing connection is installed on tensimeter and the tested pressure piping, and when tested compression shock, elongated orifice can produce bigger damping action to the mobile of liquid, refers to thereby reduced tensimeter
Swing under the hydraulic pressure vibrations.If change damping trench cross section size or damping fin group number on the damping fin, can make pressure tapping adapt to the hydraulic system of various viscosity and pressure rating.
Claims (6)
