 Stainless steel differential pressure gauge

 

CYW-152B and CYW153B stainless steel differential pressure gauges (hereinafter referred to as meters) are suitable for measuring the differential pressure and flow parameters of various liquid (gas) mediums in the chemical industry, chemical brazing, metallurgy, electric power, nuclear power and other industrial sectors. The instrument structure is made of stainless steel. The measuring system (double bellows emergency connecting parts) and pressure guiding system (including joints, pipes, etc.) are designed with special structure, advanced technology, small size, light weight and good stability. It has the advantages of long service life, novel appearance and strong adaptability. The connection style of the instrument connector is parallel (can be directly connected to the three-valve group) and oblique type, which can be adapted to the matching installation of different customers.

 

Stainless steel differential pressure gauge structure principle

 

The instrument adopts a double bellows structure, that is, two bellows are respectively installed at symmetrical positions on both sides of the "work" type bracket. The upper and lower ends of the "work" type frame are respectively a movable end and a fixed end, and the middle is connected by a spring piece; the two bellows are connected with the low pressure joint on the case, and the gear transmission structure is directly installed at the fixed end of the bracket. And connected to the movable end of the bracket through the tie rod; the dial is directly fixed on the gear transmission mechanism. When different pressures are applied (generally the high pressure end is higher than the low pressure end), the forces acting on the movable brackets of the two bellows are not equal, so that the respectively generated displacements, and the gear transmission mechanism is driven and amplified, and the pointer is deflected and indicated. The differential pressure value.
