Abstract
The utility model relates to a large-flow ball-shaped electromagnetic valve, comprising an electromagnet 1, a valve body 7, a push rod 2, an oil inlet 12 and an oil outlet 5. The push rod 2, the oil inlet 12 and the oil outlet 5 are arranged in the valve body 7. Because the inner part of the valve body 7 adopts a seat valve sealing structure, the utility model overcomes the phenomenon of tightly clamping, blocking and jam because of expansion which easily occur, and the jam because of expansion occurs because of too high oil temperature. The utility model has the advantages of simple structure, flexible and reliable action, no leakage in closing, etc.
Description
The utility model relates to a kind of solenoid valve, particularly a kind of big flow ball-type solenoid valve.
At present the benefit oil drain solenoid valve of steam turbine generator leakproof fuel cell and stator water-cooling external means need the used solenoid valve in workplace of equivalent discharge again with similar low pressure such as moisturizing solenoid valves, and present stage is sliding valve structure, normally bi-bit bi-pass formula solenoid valve.The deficiency that sliding valve structure exists is: because the error that spool and valve seat work in-process produce makes it the chucking phenomenon occur when work, this phenomenon is inevitably under normal conditions, can only be controlled in certain allowed band; The impurity of working medium makes spool stuck at work and can not work easily; Oil warm when too high spool expand and extremely can't work.These defectives have reduced the reliability of guiding valve work, and this requires solenoid valve work occasion quite reliably like this to the generator sealing oil, and it is more serious that the defective of sliding valve structure just seems, each power plant has strong complaints, and becomes the problem that presses for solution.
The utility model improves at the deficiency that prior art exists, and provides a kind of simple in structure, and break-make is active in one's movements freely, reliable operation, leak free a kind of big flow ball-type solenoid valve when closing.
The utility model is achieved by following manner: a kind of big flow solenoid valve, comprise electromagnet, valve body and interior push rod, filler opening and oil outlet thereof, it is characterized in that: the seat valve sealing configuration is adopted in the valve inner design, in oil pocket inside valve seat is housed, its lower end is shaped on boss and is installed on up and down between two oil pockets, its end is provided with the sealed steel ball that supports by Returnning spring and spring seat, and push rod withstands on the sealed steel ball, is provided with the steel ball guide sleeve between valve seat and spring.In the use, be closed condition under cold situation, when this solenoid valve energising, electromagnet core promotes push rod and backs down sealed steel ball, connects oil circuit.Outage back sealed steel ball is pressed to valve seat orifice wall end under the effect of Returnning spring makes it heavyly be closed condition.
The utility model is compared with prior art, has simple in structurely, and it is reliable to be active in one's movements, and does not have characteristics such as leakage when closing.
Fig. 1 is a general structure schematic representation of the present utility model.
Among the figure: 1 solenoid valve, 2 push rods, 3 sealed steel balls, 4 joints, 5 oil outlets, 6 flanges, 7 valve bodies, 8 Returnning springs, 9 spring seats, 10 guide sleeves, 12 filler openings, 13 valve seats.
Most preferred embodiment of the present utility model, as shown in Figure 1.A kind of big flow solenoid valve, comprise electromagnet 1, valve body 7 and interior push rod 2, filler opening 12 and oil outlet 5 thereof, it is characterized in that: the seat valve sealing configuration is adopted in valve body 7 indoor designs, in oil pocket 10 inside valve seat 13 is housed, its lower end is shaped on boss and is installed on up and down between two oil pockets, its end is provided with the sealed steel ball 3 that supports by Returnning spring 8 and spring seat 9, and push rod 2 withstands on the sealed steel ball 3, is provided with steel ball guide sleeve 11 between valve seat 13 and spring seat 9.In the use, this solenoid valve is a closed condition under cold situation, and when this solenoid valve energising, the iron core of electromagnet 1 promotes push rod 2 and backs down sealed steel ball 3, connects oil circuit.When outage back sealed steel ball 3 is pressed to valve seat 13 under the effect of Returnning spring 8 hole wall end makes it heavy is closed condition.This solenoid valve is tested through being installed on the generator sealing oil system benefit discharge equipment, solenoid valve latus rectum 12mm selects suction 8kgf electromagnet for use, and the solenoid valve two ends transfer to operating pressure differential 0.6mpa, the solenoid valve break-make is active in one's movements, does not have when reliable operation, pass valve leakage freely.On theory is calculated, when the valve seat through-hole sectional area is got 1cm
2The time, select suction 8kgf electromagnet for use, the Returnning spring minimum loading is got 1kgf, and solenoid valve two ends pressure reduction surpasses 0.7mpa and promptly can't open.And different with theoretical calculation be, when solenoid valve two ends pressure reduction leaves to 1.2mpa solenoid valve still break-make be active in one's movements freely.The reason that causes this phenomenon is when electromagnet is switched on, electromagnet core promotes impact force moment of push rod and backs down steel ball, as long as it is passable overcoming the pressure of Returnning spring after steel ball is lifted off a seat,, make solenoid valve work more reliable because this phenomenon has improved the safety coefficient of solenoid valve.Select for use the electromagnet of different size can make the different solenoid valve of latus rectum to adapt to the needs of power plant, the Applicable scope of this valve is 20～120 liters/minute.
