HOLDER OF MEASURING DIAPHRAGM (VERSIONS) AND CONNECTING FITTING Russian patent published in 2011 - IPC G01F1/42 G01F15/16 

FIELD: machine building.

SUBSTANCE: holder of measuring diaphragm consists of case equipped with through orifice and internal surface along perimetre of orifice and having certain length, of support element with thickness, less, than thickness of internal surface positioned radially from internal surface inside orifice and along whole length of internal surface, and of circular slot formed with internal surface and support element where into there is installed diaphragm unit through orifice. The diaphragm unit interacts with the support element. The holder can include at least two teeth each positioned radially from internal surface inside the orifice and interacting with ends of the diaphragm set in the orifice. Also, the first and second tooth are set below horizontal line dividing the orifice in halves. The holder can include at least one through orifice passing through the case. Fluid medium flows via this orifice, thus decreasing pressure gradient between sections before the case and after it downstream fluid medium at installation and extraction of the case.

EFFECT: reduced leaks in point of diaphragm installation inside connecting fitting; installation of diaphragm coaxially with working zone of connecting fitting.
