The gas pressure reducing valve is to control the opening of the opening and closing parts in the valve body to adjust the flow of the medium, reduce the pressure of the medium, and at the same time adjust the opening of the opening and closing parts with the help of the pressure behind the valve, so that the pressure behind the valve is kept within a certain range, and the cooling water is sprayed in the valve body or behind the valve to reduce the pressure of the medium.

The system hardware design of the valve positioner needs to reduce the interference between the analog ground and the digital ground, and at the same time make full use of the internal space of the positioner housing to divide the hardware system into two parts: the main control board and the interface board. Among them, the main control board of the valve positioner includes a single-chip microcomputer Z small system and a human-computer interaction model.

Routine maintenance is a planned overhaul before a control valve fails, which can be understood as preventive maintenance and usually includes the following tasks. 1. Stress relief Pipelines can produce various stresses due to improper combination or installation, such as thermal stress caused by high-temperature media, uneven tightening force during installation, etc.

In addition to the machinery industry, safety valves are mainly used in the chemical industry; Butterfly valves should be ...

Rules of thumb for flow characterization selection Different applications favor different valve flow characteristics. These rules of thumb do not cover all situations, but they can address many of the typical situations encountered in the process industry. Linear control valves are often chosen for pressure control, including near-constant ...

Sensor - A device or device that can sense a measured pattern and convert it into a usable output signal according to the rule. It is generally composed of sensitive elements and conversion elements. A simple sensor is composed of a component (which also serves as a conversion element), which directly outputs electricity when it senses the measurement, such as thermoelectric ...

The power of Fisher is huge, the power of example is infinite, in today's market to achieve a better survival of our goods, we must have the characteristics of our own products, from the development of our valve industry, in the current market, such equipment ...

Fisher valve positioners use an I/P electrical converter that converts an electrical signal into a gas signal. So what do we need to pay attention to during the conversion process? How do I make the switch? Here's how it goes. The I/P electrical converter of the Fisher valve positioner is made from a gas source through a constant throttle ...

In the valve design or use experience, the lifting valve packing is mostly asbestos packing or graphite packing or PTFE V-type packing, but these packings are limited by the number of valve opening and closing, that is, with the increase of the number of valve opening and closing, the packing will wear out, and the gap will gradually increase, to a certain number of times.

What is the difference between a valve limit switch and a valve positioner? Many novices don't know much about the product, and today I think I will answer the difference between the valve limit switch and the valve positioner! 1. The valve limit switch is also called a return signal, which is actually a display (reaction) valve switch ...

Butterfly valve is used in industry, its characteristics can withstand high temperature, the applicable pressure range is also high, the valve nominal diameter is large, the valve body is made of carbon steel, and the sealing ring of the valve plate is made of metal ring instead of rubber ring.
