Detailed Description
The embodiments of the present invention will be described in more detail below with reference to the accompanying drawings and reference numerals, so that those skilled in the art can implement the embodiments after studying the specification. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.
The utility model provides a saddle type pressure gauge isolator as shown in figure 1, which comprises a hollow base 1 and a hollow diaphragm seat 2 arranged on the base 1; the base 1 comprises a pressure cavity 11, a mounting groove 12 communicated with the pressure cavity 11, two connecting cavities 13 communicated with the pressure cavity 11 and extending to the outer surface of the base 1, and a welding groove 14 arranged at one end of each connecting cavity 13 facing to the outer surface of the base 1; diaphragm seat 2 with mounting groove 12 clearance fit, diaphragm seat 2 is in including leading pressure chamber 21, setting leading pressure chamber 21 orientation isolation diaphragm 22 of pressure chamber 11 one side, with lead pressure chamber 21 intercommunication's manometer interface 23.
The base is used for being connected with a measured conveying pipeline and is matched with the diaphragm seat to conduct pressure in the conveying pipeline. Specifically, two connect the chamber and communicate and the surface that the straight line extended to the base with the pressure chamber, connect the one end radius increase of chamber towards the base surface, form the welding groove, two pipeline peg graft respectively in two welding inslots to form sealedly with pipeline and welding groove welding, thereby communicate two pipeline. The installation mode is simple and convenient, and the technical difficulty is low. The difference between the radii of the weld groove and the connecting cavity may be the wall thickness of the transfer tubing.
Diaphragm seat and base accessible bolted connection, both zonulae occludens back, and the diaphragm seat stretches into in the mounting groove and with mounting groove clearance fit. The pressure gauge interface is used for connecting a pressure gauge. The pressure guide cavity and the pressure cavity are separated by the isolating diaphragm, so that corrosive media are prevented from entering the pressure gauge through the pressure guide cavity to corrode the internal structure of the pressure gauge; specifically, the isolation diaphragm can adopt a corrugated stainless steel sheet, has elasticity, can be deformed under pressure, is reset after pressure is removed, and in operation, the pressure guide cavity and a part communicated with the pressure meter and the pressure guide cavity are filled with silicon oil to serve as pressure conduction liquid. The medium in the pipeline gets into the pressure chamber, oppresses the diaphragm and produces deformation, and the rethread pressure conduction liquid is with pressure conduction for the manometer.
Preferably, the radius of the mounting groove 12 is larger than that of the pressure cavity 11, and the bottom of the mounting groove 12 is provided with a sealing ring 15. The bottom of the mounting groove forms a step-shaped structure, and the sealing ring is arranged on the step. The sealing ring can adopt a silica gel gasket.
Preferably, the bottom of the mounting groove 12 is provided with a sealing ring limiting groove for fixing the position of the sealing ring.
Preferably, the pressure guide chamber 21 is provided with a diaphragm mounting groove 24 on a side facing the pressure chamber 11, the diaphragm mounting groove 24 is tapered, and a side having a larger tapered bottom area faces the pressure chamber 11 and is provided with the isolation diaphragm 22. The conical diaphragm mounting groove is mainly used for increasing the area of the isolation diaphragm and increasing the sensitivity of the isolation diaphragm to pressure.
Preferably, the central axes of the two connecting cavities 13 coincide, and the two connecting cavities are opposite, so that the cleaning is convenient.
The foregoing is directed to one or more embodiments of the present invention, which are described in some detail and detail, but are not to be construed as limiting the scope of the invention. It should be noted that, for those skilled in the art, without departing from the concept of the present invention, several variations and modifications can be made, which all fall within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
