Abstract
The utility model discloses an extra-high tension pressure sensor which comprises a pressure gauge, a circular cavity and a connecting piece. The utility model is characterized in that the circular cavity is connected with the pressure gauge and the connecting piece, the circular cavity is internally provided with a sylphon bellows, a flange, a damped screw plug and a gasket; wherein, the sylphon bellows and the flange are welded in the circular cavity, the damped screw plug is conic and connected with the thread of the circular cavity; and the gasket is positioned at the superior part of the damped screw plug. The utility model has the advantages of simple structure, novel design, stable and reliable pressure display with a working pressure of 60 to 150Mpa, free phenomenon of rupture of the sylphon bellows, low manufacturing cost and long service life and is suitable for the working environment of hyperpressure occasions in particular.
Description
Technical field
The utility model relates to the hydraulic pressure auxiliary in the plant equipment, specifically a kind of UHV (ultra-high voltage) pressure transducer.
Background technology
Pressure transducer of the prior art has two kinds of forms, and the one, adopt oval metal tube, be full of silicone oil in the pipe, utilize not waiting of compression area to make the metal tube distortion transmit the interior silicone oil of metal tube, silicone oil makes the rotation of pressure gage spring tube Zona transformans dynamic pressure list index; The 2nd, adopt piston isolated, in plunger shaft, fill with silicone oil, piston moves up during pressurized, and piston promotes silicone oil and makes the rotation of pressure gage spring tube Zona transformans dynamic pressure list index; During the former only is suitable for, low pressure, the latter is suitable for height, middle pressure, not enough is that the silicone oil that " O " shape O-ring seal on the piston damages in the back piston chamber blows back in the pump housing, pollutes the interior material of the pump housing, and serviceable life weak point.
Summary of the invention
The purpose of this utility model is a kind of UHV (ultra-high voltage) pressure transducer that provides at the deficiencies in the prior art, and it is simple in structure, and it is reliable and stable that pressure shows, low cost of manufacture, and long service life adapts to the working environment of UHV (ultra-high voltage) especially.
The concrete technical scheme that realizes the utility model purpose is: the UHV (ultra-high voltage) pressure transducer, comprise tensimeter, circular cavity, web member, characteristics are that circular cavity is connected with tensimeter, web member, are provided with corrugated tube, flange, damping plug screw, sealing gasket in the circular cavity; Corrugated tube and flange welding place in the circular cavity, and the damping plug screw is taper, and is threaded with circular cavity, and sealing gasket is arranged on damping plug screw top.
The utility model is simple in structure, modern design, and working pressure 60～150Mpa, pressure show reliable and stable, and the bellows bursts phenomenon can not take place, low cost of manufacture, long service life adapts to the working environment of UHV (ultra-high voltage) especially.
Description of drawings

Embodiment
Consult accompanying drawing, the utility model comprises tensimeter 1, circular cavity 2, web member 7, and circular cavity 2 is connected with tensimeter 1, web member 7, is provided with corrugated tube 5, flange 6, damping plug screw 4, sealing gasket 3 in the circular cavity 2; Pack into after corrugated tube 5 and flange 6 welding in the circular cavity 2, circular cavity 2 is integrally welded with web member 7, and the formation vacuum that deflates fill with silicone oil in circular cavity 2 after screws in taper damping plug screw 4 then, refills sealing gasket 3, connects tensimeter 1 at last.During work, rising corrugated tube 5 elongations along with pressure, elongation changes along with the variation of pressure, because the elongation of corrugated tube 5, cause that the silicone oil in the circular cavity 2 is compressed, after the voltage stabilizing of compressed silicone oil by taper damping plug screw 4 thread pitches, be delivered to tensimeter 1 bourdon tube, because the distortion of bourdon tube makes gauge hand rotate.
