       Overview:

       The stainless steel differential pressure gauge (hereinafter referred to as the differential pressure gauge) is suitable for measuring the differential pressure, flow rate and other parameters of various liquid (gas) media in the process flow of industrial sectors such as chemical industry, chemical fiber, metallurgy, electric power, nuclear power and other industries. The structure of the stainless steel differential pressure gauge is all made of stainless steel, and the measurement system (double bellows and connecting parts) and the pressure guiding system (including joints, conduits, etc.) are made of special austenitic stainless steel, which has strong corrosion resistance and Resist the erosion of working environment. The overall structure of the instrument has reasonable design, advanced technology, small volume, light weight, good stability, long service life, novel appearance and strong adaptability. The connection form of the stainless steel differential pressure gauge connector is parallel (can be directly connected to the three valve group) and inclined, which can adapt to the matching installation of different users.

Structural principle:

       The instrument adopts double bellows structure, that is, two bellows are installed at symmetrical positions on both sides of the "I" shaped bracket. The upper and lower ends of the "Gong" shaped bracket are respectively the movable end and the fixed end, and the middle is connected by a spring piece; the two bellows are in a parallel state, and are respectively connected to the high and low pressure joints on the watch case by a conduit; gear transmission mechanism It is directly installed on the fixed end of the bracket and connected with the movable end of the bracket through a pull rod; the dial is directly fixed on the gear transmission mechanism.

       The working principle of the instrument: Based on the pressure-sensitive element, two bellows with the same stiffness are used, so they are forced to produce the same concentrated force on the movable bracket under the same measured medium, due to the equal moment on both sides of the spring leaf No disturbance is produced, so the bracket is still in the original position, so that the gear transmission mechanism does not move, so that the pointer still points to the low position.

       When different pressures are applied (generally the high-pressure end is higher than the low-pressure end), the forces of the two bellows acting on the movable bracket are not equal, causing corresponding displacements respectively, and driving the gear transmission mechanism to drive and amplify, after the pointer is deflected Indicates the differential pressure value between the two.
