CYW-152B series Stainless steel differential pressure gauge
CYW-152B series Stainless steel differential pressure gauge for chemical, chemical, metallurgical, power, nuclear power and other industrial sectors in the process of measuring a variety of liquid (gas) medium pressure, flow and other parameters. The instrument structure is made of stainless steel, the measurement system (double bellows emergency connection parts), pressure system (including joints, pipes, etc.) with a special structure design is reasonable, advanced technology, with small size, light weight, good stability , Long life, the appearance of new, adaptable and so on. The connection form of the instrument connection is parallel (which can be directly connected with the three-valve group) and the oblique type, which can meet the different customer's supporting installation.
Instrument with double bellows structure, that is, two bellows were installed in the "workers" on both sides of the symmetrical position of the bracket. The upper and lower ends of the "working" font bracket are the movable end and the fixed end respectively, and the middle is connected by a spring piece; the two bellows are parallel and connected with the high and low pressure connection on the case respectively; Directly mounted on the fixed end of the bracket and connected to the movable end of the bracket by means of a tie rod; the dial is fixed directly to the gear transmission mechanism.
The working principle of the instrument: Based on the sensing element using two corrugated pipes with the same stiffness, so in the same measured medium to force them to produce the same concentration of force and the activities of the bracket, the spring on both sides of the role of the moment Does not produce deflection, so the bracket is still in its original position, so that the gear transmission mechanism does not move, the pointer still refers to the zero.
When applying different pressures (generally higher than the low pressure side), the force of the two bellows acting on the movable support is not equal, so that the corresponding displacement is generated and the gear transmission is driven and amplified. Indicating the difference between the two values.
Differential pressure measurement range, nominal working pressure, accuracy grade and joint thread size:
