Embodiment Construction

[0033] The content of the present invention will be described below in conjunction with the accompanying drawings. The following description is only exemplary and explanatory, and should not have any limiting effect on the protection scope of the present invention.

[0034] Please see figure 1 , figure 1 It is a flow chart of the manufacturing method of the diaphragm device provided by the first embodiment of the present invention.

[0035] Such as figure 1 As shown, the manufacturing method of the membrane device comprises the following steps:

[0036] Step 101, fixedly connect the pre-processed flat metal disc to the pre-processed diaphragm contact body. According to the outer diameter of the drawing, the metal circular flat piece 1 is punched out, and the diaphragm connecting body 2 with a function curved surface is processed with a CNC lathe according to the drawing of the diaphragm connecting body. The outer diameter of the metal round flat piece 1 and the outer diamet...

Abstract

The invention relates to a manufacturing method of a septum device, belonging to the technical field of pressure measuring. The method comprises the following steps: a processed round metal plain film is fixedly connected with a processed septum junctor, an upper septum junctor and a lower septum junctor are connected in a sealing way, the round metal plain film is punched by pressure medium and is jointed with a function surface on the septum junctor under the pressure action of the pressure medium to generate tension set; a function surface completely coinciding with the function surface on the septum junctor is formed on the round metal plain film which is shaped as a metal film with waviness; the metal film is provided with a function surface completely coinciding with the function surface on the septum junctor, the junctor has accurate positioning and accordant die space and especially plays the role of overvoltage protection, so the metal film cannot be damaged in overvoltage, thereby the pressure propagation precision of the septum device is enhanced. The invention also provides a septum device and a septum pressure gauge.

Description

technical field [0001] The invention relates to the technical field of pressure measurement, in particular to a method for manufacturing a diaphragm device, the diaphragm device and a diaphragm pressure gauge. Background technique [0002] Diaphragm pressure gauge is a pressure measuring instrument that is not in direct contact with the medium to be measured. It is used to measure the pressure of highly corrosive, high-viscosity, easy-to-crystallize or solid floating media, or for certain measurement media that cannot Direct access to general-purpose instruments and where it is easy to clean and prevent the accumulation of sediment. Diaphragm pressure gauges are widely used in petroleum, chemical, pharmaceutical, food, paper and other industries. [0003] Diaphragm pressure gauge consists of two parts: diaphragm device and general-purpose pressure gauge. The diaphragm device mainly plays the role of pressure transmission in the diaphragm pressure gauge, so the pressure tra...
