The condensed water two-position two-way directly operated type electromagnetic valve has the advantages that flow resistance is little, and the valve is started and closed from zero differential pressure. The condensed water two-position two-way directly operated type electromagnetic valve is simple in structure, flexible and reliable in action, long in service life, and convenient to replace and maintain.
Description
Technical field
The present invention relates to solenoid valve, particularly relate to solidifying water bi-bit bi-pass direct action solenoid valve.
Background technique
Under the passive residual heat system was nonserviceabled, recycle pump quit work, and in system, temperature raises, must carry out cooling, need to be provided at the solenoid valve that this kind working condition can be opened fast, cooling by cooling water (seawater) drawing-in system, carrying out, safeguards system safety.Domestic, the solenoid valve that there is no to reach the non-conative function of this kind abroad at present.
Summary of the invention
The technical problem to be solved in the present invention is, provide a kind of passive residual heat system to nonserviceable lower cooling by the quick drawing-in system of cooling water, carrying out, safeguards system safety, and flow resistance is little, reliability is high, the solidifying water bi-bit bi-pass direct action solenoid valve of the passive residual heat system that is applicable to of long service life.
The technological scheme adopted is:
Solidifying water bi-bit bi-pass direct action solenoid valve, comprise valve body, valve disc, lower valve rod, guide way, valve pocket assembly, upper valve rod, static iron core, coil block, moving iron core, telltale, termination.Described valve body inner sleeve guide way, the valve pocket assembly lower end flange plate that is threaded, the valve pocket assembly adopts bolt to be fixedly connected with by flange plate and valve body, the in-built static iron core of valve pocket assembly and moving iron core.Described upper valve rod is installed in static iron core, and the upper valve rod upper end connects moving iron core, and lower end is threaded with the lower valve rod upper end in being installed on guide way, and lower end connects valve disc, and valve disc is suspended on lower valve rod.The exterior outer cover suit of described coil block is on the valve pocket assembly, and telltale is contained in valve pocket assembly upper end and fixes with the valve pocket assembly, and telltale is covered with upper cover, and upper cover is connected with shell, and upper cover is equipped with termination, forms the bi-bit bi-pass direct action solenoid valve.
Above-mentioned valve body adopts the direct current type valve body structure, imports and exports and takes over center line and middle mouthful of center line angle at 45 °, makes the flow resistance of medium little.
Above-mentioned bi-bit bi-pass direct action solenoid valve, be non-active normal opening structure, can directly drive moving iron core and valve disc action thereof by electromagnetic coil assembly, the circulation of blocking-up medium.
There is the pile-up welding hard alloy steel sealing lower end of above-mentioned valve disc, and sealing pair can be adjusted automatically, guarantees the sealing of valve.
Above-mentioned telltale can feed back valve position, valve opening signal is arranged and close valve signal.
Above-mentioned termination can be realized the high voltage unlatching, and after opening, low voltage keeps valve position.
The present invention have flow resistance little, from the characteristics of zero pressure difference opening and closing, its flexible movements simple in structure are reliable, long service life, replacing and easy to maintenance.Coil adopts the high temperature design, can reach long-term energising in 90 days.The suspension type design is adopted in valve disc and valve rod joint, can automatically regulate sealing surface, makes it have better sealing, and leakage rate is controlled at 1.6ml/h, and has good maintenance.
