Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail, but not as to qualification of the present utility model.
The flange arrangement that is used for pressure unit that has improved in the present embodiment as shown in Figure 1 to Figure 3.
This flange comprises: the flange face 1 of hollow, and the central column interface end 2 that protrudes from flange face is established at its middle part, front side, and screw thread 3 is established in the outside of interface end 2, and the outside is oppositely arranged parallel twice open slot 9.At least three support fixed orifices 10 are set on the flange face, establish screw thread in the support fixed orifice 10.The rear side of flange face 1 is the flange body 4 of hollow, and the housing connecting portion 5 and the annular seal groove 6 of bleeder vent, annular, seal groove 6 built-in O-ring seals are established in its outside.The front end in flange body 4 outsides is provided with housing tightening groove 7.Establish on the inwall of flange body 4 near first platform 23 of flange face 1 with near second platform of flange body 4 rear ends, the surface of two platforms is all perpendicular to the axis direction of flange.Extend to flange main body 4 rear ends always on described central column interface end 2 interior bone surfaces, until joining with first platform 23.
In the present embodiment, O-ring seals can be selected the nitrile rubber material for use.Bleeder vent is used to realize that the sensor reference value is an atmospheric pressure; Housing tightening groove 7 is used for final assembly finish after, use screw that housing is fixed on the flange body 4; The outside of interface end 2 is established screw thread 3 and is used for the field process connection, can select 1/2NPT or other on-the-spot connected mode that needs for use; Open slot 9 is mainly convenient on-the-spot installation and design; Support fixed orifice 10 is used for whole pressure unit is fixed on the on-the-spot support; Housing connecting portion 5 is that sensor flange body 4 is connected with the process of housing.
Fig. 4, the 5th, the application example of flange in the present embodiment.
Among Fig. 4, sensor 11 (can adopt ceramic capacitive sensor, diffuse si or other) is contained in the inside of flange body 4, is terminated at the surface of first platform 23 before it, by gland nut 12 set collar is compressed its rear end and realizes the fixing of sensor 11.Sensor 11 is drawn signal wire, and detected signal is connected to signal processing unit 13.Signal processing unit 13 also is the inside that is contained in flange body 4, is terminated at the surface of second platform 24 before it, and its rear end is drawn main circuit and connected lead 15; Main circuit connects the socket on the lead 15 connection mode blocking main circuit boards 19, is designed to plug type easily.By epoxy resin 14 with signal processing unit 13 embeddings on flange body 4, realize incorporate sensor construction.
