Description

A kind of novel dual-purpose valve
Technical field
The invention belongs to valve arrangement technical field, be specifically related to a kind of novel dual-purpose valve.
Background technique
Valve is the mechanical device of the flow, the flow direction, pressure, temperature etc. of the flowing medium controlling flowing, and valve is parts basic in pipe-line system.Valve pipe fitting is the same with pump technically, usually discusses as an independent classification.Valve can be used manually or handwheel, handle or pedal operation, also can by controlling pressure, temperature and the changes in flow rate of alter medium.Valve can carry out continuously or the operation repeated these changes, such as at the safety valve that water heating system or steam boiler are installed.What input according to outside in more complicated control system needs employing autocontrol valve.Valve is also divided into cast iron valve according to material, cast steel valve, stainless valve, Cr-Mo steel valve, Chrominm-molybdenum-vanadium steel valve, dual phase steel valve, Plastic valve, nonstandard customized material such as valve such as grade.When the requirement of pressure valve when being different from almost arbitrary flow by maintain constant pressure, actual reduction valve great majority have the regulating characteristic curve of decline, that is when pressure set points keeps constant, along with the rising of flow regulates pressure drop.This characteristic is owing to the mobilization force loading the flow risen along closing direction to control piston.
Filtration is a kind of technology utilizing filtering material to be separated dirty impurities in water, is sometimes used as the pretreatment of sewage, and sometimes then as final process, water outlet is for recycling or reusing.In advanced treatment of wastewater technology, generally adopt filtering technique.Current filtration all appears at people at the moment with large-scale filtration system, and for the little workshop of sewage quantity or enterprise, carry out filtering wastes resource very much, a kind ofly can seem very important to the small pressure filter that some sewage carries out Local treatment so study.Existing valve does not generally have filtering function, circulating liquid in pipeline, due to environment or the impact being subject to metallic conduit in transportation process, make easily to produce particulate contamination in circulation medium, and these impurity to continue to flow all parts in pipeline along with medium, easily wearing and tearing are caused to the valve in pipeline, the precision of the instruments such as the water meter higher to sensitivity causes damage, the normal work of valve can be had a strong impact on, pipe-line system is finally caused to break down, reduce its working life, increase maintenance cost.
