Description
A valve is a mechanical device that controls the flow rate, flow direction, pressure, temperature, etc. of a flowing fluid medium. Valves are the basic components in piping systems. Valve fittings, like pumps in technology, are often discussed as a separate category. The valve may be operated manually or with a hand wheel, handle or pedal, and may also be controlled to vary the pressure, temperature and flow rate of the fluid medium. The valve can perform continuous or repeated operations on these changes, such as safety valves installed in hot water systems or steam boilers. In more complex control systems, automatic control valves are used as required by external inputs (I. e., to adjust the changing set point of the flow through the pipeline). The automatic control valve does not need to be manually operated according to its input and setting, so that the valve can accurately control the various requirements of the fluid medium. Valves can also be divided into cast iron valves, cast steel valves, stainless steel valves, chromium molybdenum steel valves, chromium molybdenum vanadium steel valves, dual phase steel valves, plastic valves, non-standard customized valve materials, etc.
◆ Product overview
Function: vibration isolation and noise reduction, displacement compensation for pipeline engineering of protection and management system.
Application area: plumbing and ventilation pipes, water supply and drainage and circulating water pipes, etc.
◆ Typical installation diagram
Multi-level sphere structure, strong vibration absorption ability, good noise reduction effect;
Can withstand high working pressure, anti-explosive force, elastic foot;
For compression, tension, torsion deformation can play a better role in displacement compensation;
The flange and threaded joint connection that can be rotated at 360 ° makes the installation more convenient and flexible.
