Embodiment
As Fig. 1,2, shown in 3, the present invention is by valve body 1, main valve seat 2, main valve plug 3, A spring 4, valve gap 5, emergent spool 6, emergency operation bar 7, armature cover 9, electromagnet armature 10, guide's spool 11 and B spring 12 are formed, be respectively equipped with A runner 1-1 in the valve body 1, B runner 1-2, C runner 1-3 and first export mouth 1-32, C runner 1-3 is provided with A small damping device 1-31, main valve seat 2 is installed in the water inlet of valve body 1, be respectively equipped with D runner 2-1 and E runner 2-2 on the main valve seat 2, A runner 1-1 and C runner 1-3 communicate with the water intake of valve body 1 by D runner 2-1 and E runner 2-2 respectively, B runner 1-2 communicates with first export mouth 1-32 on the valve body 1, valve gap 5 is installed on the valve body 1, main valve plug 3 is installed in the water outlet 1-33 place of valve body 1, be respectively equipped with the spring mounting groove on valve gap 5 and the main valve plug 3, A spring 4 two ends valve gap 5 respectively link to each other with main valve plug 3, and lay respectively in the spring mounting groove of valve gap 5 and main valve plug 3, main valve plug 3 is provided with water outlet, the water outlet of main valve plug 3 communicates with the water outlet 1-33 of valve body 1, the water outlet place of main valve plug 3 is provided with B small damping device 3-1, be respectively equipped with F runner 5-1 on the valve gap 5, G runner 5-2 and water outlet, F runner 5-1 two ends respectively with valve body 1 on B runner 1-2 and the water outlet of main valve plug 3 communicate, G runner 5-2 two ends communicate with the A runner 1-1 of valve body 1 and the water outlet of valve gap 5 respectively, emergent spool 6 is installed in the water outlet place of valve body 1, emergency operation bar 7 is installed in emergent spool 6 one ends, and lock by locking nut, armature cover 9 is sleeved on the electromagnet armature 10, and be positioned at the guide outlet port of valve body 1, electromagnet armature 10 is provided with B spring 12 mounting grooves, B spring 12 two ends link to each other with electromagnet armature 10 respectively at armature cover 9, and an end is positioned at the mounting groove of electromagnet armature 10, guide's spool 11 is installed in electromagnet armature 10 1 ends, and is positioned at A small damping device 1-31 place.
Working principle: because working pressure is higher, flow is bigger, therefore adopt the normally closed design of leading type, under the closed state, press water is entered cavity of resorption 14 and epicoele 13 (see figure 2)s that are full of main valve plug 3 by water intake, because epicoele 13 active areas are big than cavity of resorption 14, under the hydraulic pressure effect, main valve plug 3 is in sealing state; When electromagnet gets electricly, drive on electromagnet armature 10 and the guide's spool 11 and move, pilot valve is opened, and epicoele 13 pressure reduce rapidly, under cavity of resorption 14 hydraulic pressure effects, move on the main valve plug 3, and main valve is opened; After main valve plug 3 was opened, epicoele 13 pressure of main valve plug 3 equaled the water outlet 1-33 pressure of valve body 1, when by the valve port certain flow, and main valve plug 3 travelling backwards this moment, satisfying following two conditions simultaneously is to reach steady state:
Working method: during stable operation, a small amount of high pressure water is by A small damping device 1-31, flow to outlet by guide's spool 11 then, big water gaging flows to outlet by the B small damping device 3-1 place at main valve plug 3 valve port places, and B small damping device 3-1 mainly acts on and is to form pressure reduction in main valve plug 3 upper and lower two chambeies; When the electromagnet outage, electromagnet armature 10 and guide's spool 11 reset under the effect of B spring 12, guide's spool 11 is positioned at and moves to A small damping device 1-31 one end, it is static to close back guide's spool 11 interior water, pressure raises and is inlet pressure, under 4 effects of A spring, main valve plug 3 resets, and the water outlet 1-33 of valve body 1 closes.
Can open the emergency operation valve by the emergency operation swing arm under the electromagnet failure conditions, substitute pilot valve work.
