Description
Technical field
The invention belongs to tensimeter technical field of measurement and test, specifically, relate to a kind of pressure meter calibration joint.
Background technology
Tensimeter (English name: pressure gauge) refers to take flexible member as sensitive element, measures and indicate the instrument higher than environmental pressure.Manometric application is very general, and it almost spreads all over all industrial flows and scientific research field.In fields such as heat distribution pipe network, oil gas transmission, water and air supply system, vehicle maintenance maintenance factory shops, be seen everywhere.Especially in industrial process control and commercial measurement process, because the elastic sensing element of mechanical compression table has very high physical strength and the characteristic such as convenient for production, make mechanical compression table obtain applying more and more widely.
Tensimeter passes through the elastic deformation of the sensitive element (Bourdon tube, bellows, corrugated tube) in table, then by the throw-over gear of movement in table, pressure deformation is conducted to pointer, causes that pointer rotates to show pressure.Manometric accuracy requirement is high, need manometric performance and sensitivity etc. to carry out verification completing after tensimeter assembling, traditional method is that manometric joint is connected to air machinery, again tensimeter is exerted pressure downwards, make the stable placement of tensimeter, then test, but, such method need to be longer time, be not easy to fast tensimeter be carried out to verification.
Summary of the invention
For solving above technical matters, the object of the present invention is to provide a kind of effectively fast by pressure meter calibration joint fixing tensimeter.
The present invention seeks to realize like this: a kind of pressure meter calibration joint, its key is: comprise X-over and pillar flexible pipe, this X-over axially has through hole, described X-over is followed successively by installation portion, the tight portion of bolt and connecting portion from top to bottom, described connecting portion is provided with external thread, and described installation portion is provided with at least 1 circle barb; The bottom of described pillar flexible pipe is set on described installation portion, and this pillar flexible pipe communicates with described X-over.
Adopt said structure, the connecting portion of X-over is connected with air machinery, installation portion socketed stanchion flexible pipe, pillar flexible pipe there is shrinkability, installation portion can be held tightly, guaranteed the impermeability connecting, and the barb arranging on installation portion has improved the steadiness that pillar flexible pipe is connected with installation portion, manometric joint inserts pillar flexible pipe, by the toughness of pillar flexible pipe, joint is held tightly, good airproof performance, and can not released by gas; Can be fast effective and firm installs tensimeter.
In the tight portion of above-mentioned bolt, be installed with hexagon head.
Adopt said structure, when X-over is connected with air machinery, be convenient to firmly, be convenient to install.
Above-mentioned installation portion is provided with 3 circle barbs.
Adopt said structure, 3 circle barbs can meet the stability that pillar flexible pipe is connected with X-over.
Between the tight portion of above-mentioned bolt and described connecting portion, be provided with mounting groove, sheathed O-ring seal in this mounting groove.
Adopt said structure, in mounting groove, install after O-ring seal, improved the impermeability that X-over is connected with air machinery.
The lower surface of above-mentioned through hole is to being connected to valve.
Adopt said structure, the gas that valve can be aimed at air machinery portals, and is convenient to gas flow smooth and easy.
The xsect outer ring of above-mentioned pillar flexible pipe is regular hexagon.
Adopt said structure, be convenient to pillar tube socket on X-over.
Beneficial effect: a kind of pressure meter calibration joint of the present invention, can easily load and unload tensimeter, improved manometric verification efficiency.
Accompanying drawing explanation
