Abstract
Its principal character of the present invention's " multi-purpose pressure meter " is: be the damping element of eliminating tested processing medium pressure kick with the poromerics, to isolate bellows is protective device, adapt to high viscosity, high-solidification point and the seriously pressure survey of dirty dirty medium with funnelform bellows down as the pressure intake that enlarges, be particularly useful for various pressure surveys of pumping.
Description
The present invention's " multi-purpose pressure meter " is specially adapted to the abominable pressure survey of process conditions.Though existing YK-100 type shock-proof pressure gauge also can satisfy multi-functional requirement, complex structure, manufacturing, debugging are difficult for, and existing diaphragm can not adapt to thickness, easily coagulate, shakes the pressure survey of medium.
The present invention as shown in the figure, (1) is existing tensimeter or pressure transducer, (2) be last bellows, (3) be set screw, (4) be sealing gasket, (6) be damping unit, (5) be the fastening hollow bolt of (6) and (2), (7) be diaphragm cavity, be full of spacer pad, this spacer pad is full of the cavity of the whole cavity of (2) and tensimeter that is attached thereto or pressure transducer (1), (8) be last bellows (2) and following bellows (12) or (12-1) O-ring seal between (12-2), (10) be (2) and (12) or (12-1) check nut of (12-2), (9) are set screw, and (11) are isolation diaphragm.The same with the diaphragm of routine, also can with go up bellows (2) and down bellows (22) or (12-1), the limit of (12-2) widens and is flange-like, connect with bolt.
Feature of the present invention is: between diaphragm cavity (7) and existing tensimeter or pressure transducer (1) damping unit (6) is arranged, it is sheet or the column of being made by poromerics, can be installed in position as shown in the figure, also can be installed in certain position at the pressure entrance place of tensimeter or pressure transducer (1), arrive the pressure-sensitive parts of tensimeter or pressure transducer after making tested processing medium pressure pulse by this poromerics again, because poromerics is made up of a large amount of micropores, spacer pad is again pure being enclosed in the airtight system, so this damping unit (6) can steady in a long-termly move; Pressure survey to easy coagulation medium, following bellows should be the heavy caliber funnel-form as figure (12-1), just and do the convection current heat interchange between the process stream, the effect that produces " self-heat conserving " is solid with anti-freezing, simultaneously, some the particle foreign material in the processing medium also can sink to leaving bellows naturally under the effect of gravity, and the effect that produces " cleaning certainly " is with anti-clogging, because this bigbore funnel-form also is applicable to the pressure survey of " high thickness " medium certainly; The pressure survey of commute " wall built-up hardens " medium, following bellows should be the tubular short tube as (12-2), make whole isolated diaphragm (11) as far as possible near-earth be in the process environments, diaphragm is not hardened and normal operation; Pressure survey to Korrosionsmedium is the same with conventional diaphragm, adopts the anticorrosion material or adds the teflon sheath again.
Most preferred embodiment: isolate bellows and should adopt as figure (2), (10), (12-1) structure, damping unit is installed in the position as figure (6), and tensimeter (1) can be a bourdon gauges.
About 200 yuan of this " multi-purpose pressure meter " every cost, and every price of existing YK-100 type shock-proof pressure gauge is wanted 495～650 yuan, two compare, and superiority of the present invention is apparent.
Claims (8)

3, according to claim 1, damping unit (6) is characterized in that being installed in the suitable position between the pressure-sensitive parts of diaphragm cavity (7) and pressure gauge sensor (1).
4, according to claim 1, following bellows (12), its feature belongs to conventional type, is used for the pressure survey of more satisfactory processing medium.
5, according to claim 1, following bellows (12-1) is characterized by the heavy caliber funnel-form, is used for thickness, easily coagulates, the pressure survey of dirty dirty medium.
6, according to claim 1, following bellows (12-2) is characterized by the tubular short tube, is used for the processing medium pressure survey of wallboard knot easy to hang.
7, according to claim 1, last bellows (2), O-ring seal (8), isolation diaphragm (11), down bellows (12) or (12-1), (12-2), it is characterized by and select for use the anticorrosion material to make, or to (2), (11), (12) or (12-1), the position of (12-2) contact process medium adds the teflon sheath again, can be used for the pressure survey of Korrosionsmedium or strong corrosive medium.
8, according to claim 1, tensimeter or pressure transducer (1), it is characterized by and to select existing various tensimeter for use, comprise common indicating pressure gauge, electro connecting pressure gauge, pressure gauge with transmission device, the tensimeter of anti-environmental vibration cooperate with isolation bellows of the present invention with pressure transducer and various hope and improve the various tensimeters of former instrument function.
