Abstract
The utility model provides an oil-filled pressure gauge, which is a meter for the measurement of pressure. The utility model is composed of a gauge case, a driving mechanism, a gauge stand, and a joint, wherein, the flange of the gauge case is provided with a rubber washer; an annular groove is positioned on the gauge stand; an O-shaped sealing ring is arranged in the annular groove; a small cross groove and a technological groove are positioned on a damper valve; the outer surface of the damper valve is provided with an annular groove and a small hole; imperfect threads are positioned at one side of the damper valve, and the other side is provided with completely threads. A fixing clip is positioned in the gauge case, and the gauge stand is installed in the fixing clip. The utility model has the advantages that the sealing performance is good; the effect of reducing pressure and damping is better than old type gauzes; the cost of manufacturing, which is only half of the cost of the old type gauzes, is low; the service life is long; the maintenance is convenient.
Description
The utility model relates to a kind of measuring instrumentation, particularly a kind ofly is used for tonometric filling type tensimeter.
The existing manometric sealing of filling type is generally disposable sealing or screw-type connecting structure.The damping shock absorption mode is the capillary cellular type or adds a damper in addition.The weak point of this kind structure is: sealing property is bad, easily leaks, and is not good to reducing the pulse vibrating effect.Simultaneously, because its complex structure causes its manufacturing cost higher, maintenance difficult.
The purpose of this utility model is to disclose a kind of filling type tensimeter at aforementioned the deficiencies in the prior art, this table can improve manometric sealing property and damping shock absorption performance, simplified the structure of table, prolong the serviceable life of table, thereby also reduced the manufacturing cost of oil dumped pressure gauge, also provide convenience for manometric manufacturing and maintenance.
The utility model is achieved in that the filling type tensimeter, it is by watchcase 4, be contained in gear train and gauge stand 7 on the watchcase 4 and pressure tapping 9 compositions in the watchcase 4, wherein: a, rubber washer 2 is housed at the upper end flange place of watchcase 4, in rubber washer 2, adorn a table and cover 3, be pressed with table upper casing 1 at the flange position of watchcase 4 and the outer rim of rubber ring 2.One ring groove is arranged on the right side of b, gauge stand 7, and O RunddichtringO 8 is contained in this groove.C, orifice valve 10 left ends have a little translot 14, right-hand member has a technology groove 11, one ring groove 15 is arranged on the outside surface of the middle part of orifice valve 10, aperture 13 is arranged in ring groove 15, this aperture 13 communicates with aperture 12 on the orifice valve 10, ring groove 15 left part of orifice valve 10 are imperfect thread, and the right side is divided into perfect thread.D, be fixed with fixing card 6 on watchcase 4, gauge stand 7 is installed in the fixing card 6.
Good effect of the present utility model is: compare good seal performance of the present utility model with present filling type tensimeter, its damping shock absorption effect is also far above prior art.The manometric manufacturing cost of this filling type only is 50% of an old telogenesis basis, and another advantage of this table is its long service life, and maintenance is convenient.

Below in conjunction with accompanying drawing the utility model is described in further detail:
As shown in Figure 1, 2, 3.The filling type tensimeter is by watchcase 4, be contained in gear train and gauge stand 7 on the watchcase 4 and pressure tapping 9 compositions in the watchcase 4, wherein: a, rubber washer 2 is housed at the upper end flange place of watchcase 4, in rubber washer 2, adorn a transparent table lid 3, be pressed with table upper casing 1 at the flange position of watchcase 4 and the outer rim of rubber ring 2.This kind structure can guarantee that the oil in the tensimeter is unlikely and ooze out that the aqueous vapor of outside can not infiltrated in the table yet from tensimeter.If pressure gauge component can be used instrument and will go up watchcase 1 and pry open when damaging, change and repair the damage element, will go up watchcase 1 after repairing again and be mounted on the watchcase 4 and get final product.One ring groove is arranged on the right side of b, gauge stand 7, and O RunddichtringO 8 is contained in this groove.When rotational pressure meter connector 9, gauge stand 7 and pressure tapping 9 are tightened up, and the O RunddichtringO deforms simultaneously, plays the leakproof effect.C, orifice valve 10 left ends have a little translot 14, right-hand member has a technology groove 11, one ring groove 15 is arranged on the outside surface of the middle part of orifice valve 10, aperture 13 is arranged in ring groove 15, this aperture 13 communicates with aperture 12 on the orifice valve 10, ring groove 15 left part of orifice valve 10 are imperfect thread, and the right side is divided into perfect thread.This structure has guaranteed that the tensimeter work time pulse flows in the ring groove 15 by afterbody aperture 12 and aperture 13 earlier towards medium, then through the imperfect thread of orifice valve left end and the interstitial flow between the internal thread and go out, little translot 14 through front end flows in the flexible member 5, to reach the purpose of gaging pressure.The effect of orifice valve 10 is to have the pulse vibrations, to the destructive extremely strong unsettled measuring media of watch core, the spirality micropore and the front end sulculus that constitute via pore, ring groove, imperfect thread have four road dampings altogether, eliminate the pulse vibrations of medium to greatest extent, make it to become measured medium stably, reaching accurate demonstration gaging pressure, and the serviceable life of improving table.D, be fixed with fixing card 6 on watchcase 4, gauge stand 7 is installed in the fixing card 6.This kind structure can guarantee assembly quality and improve efficiency of assembling.
