نبذة شخصية: How does a pressure gauge work?

Pressure gauges work differently depending on the type. In industrial measurement technology, two different types of pressure gauges are used - Bourdon tube pressure gauges and diaphragm pressure gauges. They have different functional principles and are therefore suitable for different applications. With Bourdon tube pressure gauges, the pressure is measured by a Bourdon tube transmitting pressure directly to the pointer. Inside the case, there is a curved tube, into which the medium enters and causes the Bourdon tube to stretch. This stretching is transmitted to the movement via a link and a toothed segment and displayed on the dial as a corresponding deflection.


What is a solenoid valve and how does it work?
What is a solenoid valve?

The definition of a solenoid valve ;is an electro-mechanical valve that is commonly employed to control the flow of liquid or gas. There are various solenoid valve types, but the main variants are either pilot operated or direct-acting. Pilot-operated valves, the most widely used, utilize system line pressure to open and close the main orifice in the valve body. ;

While Direct operated solenoid valves directly open or close the main valve orifice, which is the only flow path in the valve. They are used in systems requiring low flow capacities or applications with low-pressure differential across the valve orifice.


How solenoid valves function

How a solenoid valve works is by controlling the flow of liquids or gases in a positive, fully-closed, or fully-open mode. They are often used to replace manual valves or for remote control. Solenoid valve function involves either opening or closing an orifice in a valve body, which either allows or prevents flow through the valve. A plunger opens or closes the orifice by raising or lowering within a sleeve tube by energizing the coil.

Solenoid valves consist of a coil, plunger, and sleeve assembly. In normally closed valves, a plunger return spring holds the plunger against the orifice and prevents flow. Once the solenoid coil is energized, the resultant magnetic field raises the plunger, enabling flow. When the solenoid coil is energized in a normally open valve, the plunger seals off the orifice, which in turn prevents flow.
