Abstract
The utility model belongs to the technical field of thermodynamic measurement and relates to a pressure gauge junction, comprising a pressure tap, a cock joint, a sleeve, a core tube and a sealing gasket. A hole-plate restrictor and a condenser are arranged inside to reduce the influence by shock and temperature of the high-temperature medium on a pressure gauge and to give the pressure gauge antifreeze or anticorrosion performance. The pressure gauge junction can also be used as an accessory to the pressure gauge.
Description
The utility model belongs to the thermal measurement field.
At present, every pressure vessel and the equipment that needs monitor pressures all must install tensimeter, to show the pressure of each monitoring point.Under the table of boiler pressure gauge, all must the bend pipe that store condensate water be housed supporting use, to prevent that high-temperature vapour from directly entering the tensimeter spring tube bending, its common form has spiral tube, U type pipe etc., and the tensimeter that use is equipped with trap has these weak points, its position that takes up room is big, and owing to form, make totally to seem comparatively messy also complicated manometric installation and overall appearance by the tubular material bending; Its poor rigidity makes tensimeter base supports rigidity obviously not enough, and the influence and the purposes that are subject to shake are single, and cost is higher.On pressure vessel to the medium that is corrosive; in order to prevent that pressure gage spring tube is corroded; a kind of fluid-tight type tensimeter of normal employing; with etch-proof diaphragm bourdon tube and Korrosionsmedium are isolated, adopt a kind of anticorrosion spacer assembly that is called the insulation blocking jar in addition, it is contained on the connecting pipe of tensimeter and container; thereby play etch-proof effect; but also exist the cost height, purposes is single, installs and uses weak points such as inconvenience.
The purpose of this utility model provides a kind of novel pressure tapping, makes tensimeter both have anticorrosion, the anti-freeze performance, and the while has also been improved the accuracy of pressure gauge reading, and is specious, economical and practical, prolongs manometric serviceable life.
Pressure tapping of the present utility model is by pressure gauge connection, the cock interface, and sleeve pipe, core pipe and liner five parts are formed.The form of core pipe can be triangle, quadrangle, pentagon and sexangle.
The upper end of pressure gauge connection 2 is the tensimeter link, is provided with the orifice-plate type flow controller that 2-6 annular distribution aperture 5 formed at bosom, is provided with the condenser of being made up of the sleeve pipe 6 and the core pipe 7 of upper end closed in the cock interface 4.
Pressure tapping of the present utility model is the tensimeter link in the upper end of pressure gauge connection 2, be provided with the orifice-plate type flow controller that the aperture 5 of 2-6 annular distribution is formed at bosom, the pressure of fluctuation pressure or big ups and downs obtains decay by the damping of this orifice-plate type flow controller; Be provided with condenser in the cock interface 4, its sleeve pipe 6 and core pipe 7 by upper end closed is formed, when measured medium enters in the core pipe 7 inwall and the transmission of the generation of the passage between the core pipe 7 buffer brake by sleeve pipe 6 from the lower end (measured medium inlet end) of cock interface 4, and the inside and outside aggegation condensed fluid at sleeve pipe 6 has cut off the circulation path between high-temperature steam medium and the tensimeter; (being the inside and outside of sleeve pipe 6) hole in cock interface 4 can charge into anticorrosive or freeze-point depressant according to different supporting request for utilizations.If charge into (perhaps other are not subjected to the corresponding anticorrosive that measured medium influences) such as transformer oil or kerosene, prevent that corrosive medium is to manometric corrosion; If charge into chlorination silicone oil or ethylene glycol (perhaps other is not subjected to the corresponding freeze-point depressant of measured medium influence), can prevent tensimeter freezing under cryogenic conditions.
The utility model has reduced environmental vibration to manometric influence because the rigidity of support of tensimeter pedestal is improved, and simultaneously owing to be provided with the orifice-plate type flow controller in joint, has also weakened the pulse of measured medium pressure or fluctuation to manometric influence; Owing in joint, be provided with condenser, prevented the influence of pressure gage spring tube expanded by heating.Not adding under any other annex, enlarged manometric usable range, both can be used on the boiler, can charge into anticorrosive or freeze-point depressant according to request for utilization again, make tensimeter on the pressure vessel under be corrosive medium or the cryogenic conditions.Pressure tapping of the present utility model also has rational in infrastructure, and it is more extensive practical, accurately reliable that tensimeter is obtained.Be matched in other manometer such as vacuum meter according to actual needs, pressure vacuum meter is first-class.
Fig. 1 is a section of structure of the present utility model.
Among the figure: 1,3 is liner, and 2 is pressure gauge connection, and 4 are the cock interface, and 5 is throttling pore, and 6 is sleeve pipe, and 7 is triangle core pipe.
Claims (1)
1, a kind of pressure tapping, by pressure gauge connection 2, cock interface 4 and sealing gasket 1 are formed, it is characterized in that the upper end bosom of pressure gauge connection 2 is provided with the orifice-plate type flow controller of aperture 5 compositions of 2-6 annular distribution, in cock interface 4, be provided with the sleeve pipe 6 of upper end closed and the condenser and the liner 1,3 of core pipe 7 compositions and form.
