Detailed description of the invention
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, pilot valve 11 and B spring 12 form, A runner 1-1 is respectively equipped with in 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 arranged on the water inlet of valve body 1, main valve seat 2 is respectively equipped with D runner 2-1 and E runner 2-2, A runner 1-1 and C runner 1-3 communicates with the water inlet of valve body 1 respectively by D runner 2-1 and E runner 2-2, B runner 1-2 communicates with the first export mouth 1-32 on valve body 1, valve gap 5 is arranged on valve body 1, main valve plug 3 is arranged on the delivery port 1-33 place of valve body 1, valve gap 5 and main valve plug 3 are respectively equipped with spring fitting groove, A spring 4 two ends are connected with main valve plug 3 with valve gap 5 respectively, and lay respectively in the spring fitting groove of valve gap 5 and main valve plug 3, main valve plug 3 is provided with delivery port, the delivery port of main valve plug 3 communicates with the delivery port 1-33 of valve body 1, the water outlet of main valve plug 3 is provided with B small damping device 3-1, valve gap 5 is respectively equipped with F runner 5-1, G runner 5-2 and delivery port, F runner 5-1 two ends communicate with the delivery port of the B runner 1-2 on valve body 1 and main valve plug 3 respectively, G runner 5-2 two ends communicate with the A runner 1-1 of valve body 1 and the delivery port of valve gap 5 respectively, emergent spool 6 is arranged on the water outlet of valve body 1, emergency operation bar 7 is arranged on emergent spool 6 one end, and locked by locking nut, armature cover 9 is sleeved on electromagnet armature 10, and be positioned at the guide exit of valve body 1, electromagnet armature 10 is provided with B spring 12 mounting groove, B spring 12 two ends are overlapped 9 with armature respectively and are connected with electromagnet armature 10, and one end is positioned at the mounting groove of electromagnet armature 10, pilot valve 11 is arranged on electromagnet armature 10 one end, and be positioned at A small damping device 1-31 place.
Operation principle: because operating pressure is higher, flow is larger, therefore the normally closed design of pilot-operated type is adopted, under closure state, press water is entered the cavity of resorption 14 and epicoele 13 (see Fig. 2) that are full of main valve plug 3 by water inlet, due to epicoele 13 active area, comparatively cavity of resorption 14 is large, and under hydraulic pressure effect, main valve plug 3 is in sealing state; When electromagnet obtains electric, drive in electromagnet armature 10 and pilot valve 11 and move, pilot valve is opened, and epicoele 13 pressure reduces rapidly, under the effect of cavity of resorption 14 hydraulic pressure, main valve plug 3 moves, and main valve is opened; After main valve plug 3 is opened, epicoele 13 pressure of main valve plug 3 equals the delivery port 1-33 pressure of valve body 1, when by valve port certain flow, and now main valve plug 3 travelling backwards, meet following two conditions is reach stable state simultaneously:
Working method: during steady operation, a small amount of water under high pressure is by A small damping device 1-31, then outlet is flowed to by pilot valve 11, large water gaging flows to outlet by the B small damping device 3-1 place at main valve plug 3 valve port place, and B small damping device 3-1 Main Function is to form pressure reduction in upper and lower two chambeies of main valve plug 3; When electromagnet power-off, electromagnet armature 10 and pilot valve 11 reset under the effect of B spring 12, pilot valve 11 is positioned at and moves to A small damping device 1-31 one end, after closing, in pilot valve 11, water is static, pressure raises as inlet pressure, under A spring 4 acts on, main valve plug 3 resets, and the delivery port 1-33 of valve body 1 closes.
Open emergency operation valve by emergency operation swing arm under electromagnet failure conditions, substitute pilot valve work.
