Description
Technical field
The present invention relates to the valve class, relate in particular to a kind of pure water electromagnetic switch 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 selector valve research.
The pure water selector valve of development mainly contains two 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 object of the present invention is to provide a kind of pure water electromagnetic switch valve, it is disconnected to be used to control the liquid circulation, realizes not having and leaks, and alleviates phenomenons such as cavitation erosion, corrosion simultaneously, is higher than in being applicable under the aqueous medium environment.
The technical solution adopted for the present invention to solve the technical problems is:
Right-to-left is equipped with the spring valve pocket that radially has two groups of inclined holes successively in valve body hole, adjust ring, the step post, radially have the four ports valves cover and the two ports valve covers that radially have one group of inclined hole of one group of inclined hole, on the spring valve pocket right-hand member roundlet cylinder modulating valve upper shield is housed, the valve pocket lid is pressed in and stretches out on the outer spring valve pocket shoulder of valve body, the force amplificatory structure that the dry type DC electromagnet is housed is pressed in the push rod left side, spring seat one end that is contained in the spring valve pocket withstands on the Returnning spring, the spring seat the other end withstands on and is contained on the ceramic ball of adjusting in the ring, be contained in the step post, one end of the push rod of four ports valves cover and two ports valves cover withstands on the ceramic ball, and the other end of push rod withstands on the force amplificatory structure;
Valve body top has water intake, backwater mouth, valve body lower portion has the runner that is communicated with two ends, the valve body left and right sides, when the dry type DC electromagnet gets when electric, force amplificatory structure promotes push rod and moves right, ceramic ball and step post leave, liquid stream by water intake, spring valve put right-hand member inclined hole, adjust the inclined hole that ring center hole, step post center hole, two ports valves put, enter backwater mouth, the pure water switch valve can be through-flow; When dry type DC electromagnet dead electricity, Returnning spring promotes spring seat to left movement, and ceramic ball and step post hide, and the pure water switch valve cuts off liquid stream; In the valve working procedure, part liquid stream is arranged through entering the Returnning spring chamber, part liquid stream enters left end push rod chamber through the radially inclined hole that valve flowing channel, two ports valves put, and makes the suffered fluid pressure balance of push rod, spring seat and ceramic ball.
Seal with O-ring seals between two ports valves cover and the valve body, add the ring washer sealing with O-ring seals between four ports valves cover and the valve body, add the ring washer sealing with O-ring seals between step post and the valve body, with O-ring seals sealing, add ring washer with O-ring seals respectively between two ports valve covers, four ports valves cover and the push rod and seal ring adds the ring washer sealing between spring valve pocket and the valve body.
The present invention compares with background technique, and the beneficial effect that has is:
1, adopt the covering between ceramic ball spool and the step post or leave to realize that the liquid circulation breaks, can realize not having and leak, because carrying out break-make by ceramic ball switches, the stroke of ceramic ball is exactly the opening amount of valve, thereby stroke is short, shorten the commutation and the resetting time of pure water Solenoid ball valve greatly, improved reaction velocity;
2, valve body and valve pocket, all with O-ring seals sealing, efficiently solve the pure water switch valve and leak serious problem between valve pocket and the push rod, the reasonable Arrangement of runner makes push rod bar and the suffered fluid pressure balance of ceramic ball, can guarantee that the flexible movements of ball valve core are reliable, be applicable to the mesohigh operating conditions;
4, this valve has simple in structure, easy for installation, good manufacturability, is easy to standardized characteristics, is suitable for producing in serial form;
5, all elements of valve have all adopted anti-corrosion non-corrosive material, can guarantee that valve has the long life-span in the aqueous medium working environment.
