Abstract
The present invention's " manometric antishock device of common Y type " belongs to the instrument and meter for automation class.The technical issues that need to address are to make existing common Y type tensimeter can be used for that tested processing medium parameter is made dither or process equipment, pipeline has the pressure survey under the sharp pounding environment.The major technique feature is a flexible and inertial device between bourdon tube and sectional wheel and mandrel and pointer, and the power of vibrations is absorbed by elasticity and inertia, and pointer can more stably be shown.
Description
The invention belongs to the pressure measuring instruments in the instrument and meter for automation.
The bourdon gauges of prior art can not antidetonation, no matter the vibrations of the pulsation of tested processing medium pressure parameter or process equipment, pipeline environment all make the display pointer of instrument rock even can't look and read.
Purpose of the present invention makes existing bourdon gauges have anti-seismic performance, is specially adapted to that tested processing medium pressure parameter is made dither or process equipment, pipeline has the pressure survey under the sharp pounding environment.
The bourdon gauges of prior art as shown in the figure pointer (1) and mandrel (4) between be to be rigidly connected, any vibrations of mandrel all directly reach pointer, influence is looked and is read.Feature of the present invention is: elasticity and inertial device are arranged between pointer and mandrel, and mandrel (4) drives pointer again by elastic device (2) and inertial device (3).The power that forces pointer to do laterally rotation of moment is absorbed by elastic device (2) earlier, reaches the inertial device (3) with certain mass again, just orders about pointer at last and rotates.When the power of doing forward and reverse rotation of high frequency successively occurred, being reflected on the pointer (1) here was to cancel out each other, and pointer (1) can more stably be shown.
Be rigidly connected by connecting rod (6) between bourdon tube of the bourdon gauges of prior art (5) and the sectional wheel (7).Any shake on the bourdon tube (5) all synchronously reaches sectional wheel (7), and sectional wheel (7) influences looking of pointer (1) and reads by gear and mandrel (4) commissure.Feature of the present invention is: the connecting rod (6) between bourdon tube (5) and sectional wheel (7) is an elastic device, and sectional wheel (7) becomes the inertial device with certain mass here.The power of the vibrations of bourdon tube (5) is absorbed by elastic device (6) earlier, reaches inertial device-sectional wheel (7) again.When the making forward and reverse power and successively occur of high frequency, being reflected on the sectional wheel (7) is to cancel out each other, and mean value reaches mandrel (4) more stably, makes pointer (1) obtain more stably showing.
Most preferred embodiment: the most handy elastic caoutchouc of elastic device of the present invention (2) is made, and inertial device (3) is a metal section with suitable quality preferably, and elastic link (6) straight-arm part is the spring of handy suitable elasticity.Preferably the structure of this device is all adopted in piece number (2), (3), (6), (2), (3) that also can only adopt this device, and (6) still with original be rigidly connected or only adopt this device (6) and without (2), (3) of this device.
The advantage that the present invention compared with prior art has:
1. looking of stable pointer read.
2. weaken the vibration between sectional wheel (7) and mandrel (2) gear, reduce the wearing and tearing of gear, prolong the service life of bourdon gauges.
Figure of description is the structural representation that the present invention has the bourdon gauges of antishock device.
Claims (4)
1, the present invention " the manometric antishock device of common Y type " is specially adapted to that tested processing medium parameter is made dither or process equipment, pipeline has the pressure survey under the sharp pounding environment.The common Y type tensimeter of prior art under these conditions, not only gauge pointer rocks even can't look and read, and the wearing and tearing of accelerating gear parts, influences the serviceable life of instrument.Feature of the present invention is: go up flexible device (2) and inertial device (3) at mandrel (4), pointer (1) links to each other with inertial device (3), and be connected to an elastic device (6) between bourdon tube (5) and the sectional wheel (7), can (2), (3), (6) structure adopts simultaneously, also can adopt wherein one or binomial.
2, according to claim 1, elastic device (2) can be an elastic rubber product, also can be a spring assembly.
3, according to claim 1, inertial device (3) can be one to have the metal or the nonmetal pipeline section of suitable quality.
4, according to claim 1, elastic device (6) can be the moderate volute spring of an elasticity, also can be other resilient materials, as rubber or reed.
