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 pressure gauge with an adapter as shown in figures 1-2, which comprises a gauge head 1 and a hollow adapter 2, wherein a pressure cavity 21 and two connecting cavities 22 communicated with the pressure cavity 21 and used for connecting a conveying pipeline 5 are arranged in the adapter 2, one end of each connecting cavity 22 facing to the outside is provided with a welding groove 23, the adapter 2 is also provided with a first flange 3, and an inner cavity 31 of the first flange 3 is communicated with the pressure cavity 21; gauge outfit 1 be provided with first flange 3 bolted connection second flange 4, second flange 4 orientation one side of first flange 3 is provided with connecting pipe 41, connecting pipe 41 with inner chamber 31 cooperation, and be provided with and be used for the isolation diaphragm 43 that separates first flange 3 and second flange 4.
The gauge head can be a spring tube type pressure gauge in the prior art and is used for measuring and displaying the pressure. The adapter is used for installing the gauge outfit on pipeline, simultaneously with the pressure conduction in the pipeline for the gauge outfit, specifically, two connect chamber and pressure chamber intercommunication and the surface of straight line extension to the adapter, connect the one end radius increase of chamber towards the adapter surface, form the welding groove, two pipeline peg graft respectively in two welding grooves to form sealedly with pipeline and welding groove welding, two connect chamber and pressure chamber with two pipeline intercommunications. 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. The first flange and the second flange can be connected through bolts, and after the first flange and the second flange are tightly connected, the connecting pipe extends into the inner cavity of the first flange and is matched with the inner cavity.
The isolation diaphragm is used for separating the first flange from the second flange, and prevents a medium from entering the gauge head through the second flange to corrode the internal structure of the gauge head, so that the gauge head can measure the pressure of the corrosive medium. Specifically, the isolation diaphragm can adopt a corrugated stainless steel sheet, has elasticity, deforms when being pressed, resets when pressure is removed, and in operation, silicone oil is filled in the connecting pipe, the cavity of the second flange and the part of the meter head communicated with the cavity of the second flange to serve as pressure conduction liquid. The medium in the conveying pipeline enters the pressure cavity, presses the isolation diaphragm to deform, and then transmits the pressure to the gauge outfit through the pressure transmission liquid.
Preferably, the second flange 4 is provided with a sealing groove 44 surrounding the connecting pipe 41, a sealing ring 45 is arranged in the sealing groove 44, and the first flange 3 is provided with a convex ring 32 matched with the sealing groove 44. After the first flange and the second flange are tightly connected, the convex ring extends into the sealing groove to press the sealing ring, so that a sealing structure is formed. The sealing ring can be a flange gasket made of rubber or silica gel.
Preferably, a diaphragm installation groove 42 is formed in one side of the connection pipe 41 facing the inner cavity, the diaphragm installation groove 42 is tapered, and the side having the larger tapered bottom area faces the inner cavity 31 and is provided with the isolation diaphragm 43. 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 adapter 2 and the first flange 3 are integrally formed.
Preferably, said head 1 and said second flange 4 are screwed.
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.
