Description
Technical field
The utility model relates to the valve class, relates in particular to a kind of pure water hydraulics Solenoid ball valve.
Background technique
The pure water hydraulics technology has the unique advantage of the feature of environmental protection and flame retarding because of it, just be subjected to the extensive attention of countries in the world hydraulic pressure circle, and water hydraulic components also becomes one of key content of research.Selector valve is one of the most key valve element of hydraulic system, also becomes research emphasis at the research of the selector valve that is applicable to the pure water hydraulics system.
Traditional oil pressure selector valve mostly is slide valve type, rotary valve type or cone valve type.The suffered unbalanced force of slide valve type and rotary valve type change-over valve core is very little, and needed steering force is also less, but needs to guarantee the gap of relative movement between spool and valve opening, leaks often bigger.Especially for aqueous medium, the viscosity of water is low can to increase leakage loss, and when identical with pressure reduction, the leakage loss of the hydraulic pressure selector valve of same specification is tens of times of oil pressure selector valve in the gap.Thereby, for just reduce to leak must be gap design very little, this must bring very big difficulty to processing, very easily occurs stopping up during kinematic pair work simultaneously, stuck phenomenon.The leakage of cone valve type selector valve is very little, but the axial hydraulic force unbalance that spool is subjected to, required steering force is also bigger.In addition, because the compressibility of water is little, rigidity is big, the compression shock that is produced when the pure water selector valve switches suddenly is even more serious.
In addition, the pressure for vaporization height of water make water electrode easily vaporize and boiling, thereby under the same conditions, the cavitation erosion degree that the pure water selector valve suffers is than the strong hundreds of times of oil pressure selector valve; Compare with mineral oil, aqueous medium corrosivity is very strong, and the destruction of corrosive action makes prior oil pressure selector valve material all not be suitable for aqueous medium.
Therefore, how to prevent to leak, reduce reversing impact, reduce corrosion and effectively suppress cavitation erosion, improve quiet dynamic characteristic, become the key point of pure water hydraulics selector valve research.
The pure water hydraulics selector valve of development mainly contains 2 kinds of forms in the world at present:
First kind is to adopt the cone valve type structure.As the pure water selector valve of Finland Danfoss company development etc.It is formed by being installed in two groups of main coning valves on the valve body, two pilot-actuated valves that are designed to the end cap flange and two unidirectional controlled cone valves symmetrically.Such valve conveyance capacity is strong, cavitation resistive property good.But it is subjected to the influence of machining accuracy, can't overcome very pressure of axial injustice fully, and needed steering force is also bigger.
Second kind is to adopt slide-valve structure.As the pure water selector valve of German hauhinco company development etc.Such valve leaks for reducing, very little the design of the matching gap between spool and the valve pocket, and so little gap has proposed very harsh requirement for the processing technology of valve, has improved difficulty of processing and processing cost greatly.In addition, so little gap is also easily by the impurity jam, so its application has been subjected to considerable restraint.
Summary of the invention
The purpose of this utility model is to provide a kind of pure water hydraulics Solenoid ball valve, is used to improve the quiet dynamic characteristic of selector valve, realizes not having leaking, and alleviates phenomenons such as cavitation erosion, corrosion simultaneously, is higher than in being applicable under the aqueous medium environment.
