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

Corrugated compensator is also called expansion joint, or expansion joint. It is composed of bellows (an elastic element) and end pipes, brackets, flanges, conduits and other accessories that constitute its working body. It belongs to a compensation element. Use the effective telescopic deformation of the bellows of its working body to absorb the dimensional changes of pipelines, conduits, containers, etc. caused by thermal expansion and contraction, or compensate the axial, lateral and angular displacement of pipelines, conduits, containers, etc. It can also be used for noise reduction and vibration reduction, especially for hot air pipes and smoke pipes.

Note: The axial internal pressure type corrugated compensator is mainly used to compensate the axial displacement, and can also compensate the lateral displacement or the axial and lateral composite displacement. It has the ability to compensate the angular displacement, but it is generally not used to compensate the angular displacement. The above data is normal pressure 1.0MPa, if there are special requirements, can be made separately.
