Face, valve rod 2 are arranged in valve body 4, and handwheel 1 is fixed at 2 upper surface of valve rod, and valve plate 5 is fixed at 2 lower surface of valve rod simultaneously
In valve body 4,4 two sides of valve body offer water inlet 6 and water outlet 7 respectively, and sealing mechanism is fixed at 4 middle part of valve body,
Anti-backflow mechanism is fixedly installed in water outlet 7, filter mechanism is arranged at water inlet 6 and is located at outside valve body 4；Handwheel 1
On be fixedly installed anti-slip ring.
Sealing mechanism includes expanding block 10, axle sleeve 13 and barrier rubber block 14, is formed on valve body 4 positioned at 2 two sides of valve rod convex
Block 12, restraining position ring block 8 is arranged below valve rod 2, and expanding block 10 is set on valve rod 2 and is arranged by gasket 9 in 8 following table of stop collar
Face, the setting of expanding block 10 offer expansion slot 11 on 12 upper surface of convex block, expanding block 10 and valve body 4, and axle sleeve 13 is set in valve
On bar 2 and it is located at 12 lower surface of convex block, barrier rubber block 14 is set in 5 junction of valve rod 2 and valve plate, table on barrier rubber block 14
Face is against 4 inner wall of valve body；14 edge of barrier rubber block is provided with recess.
Anti-backflow mechanism includes pillar 17 and two baffles 21, and fixed link 15, fixed link are fixedly installed at water outlet 7
15 both ends offer through-hole 16, and pillar 17 is arranged through fixed link 15, and pillar 17 is fixedly installed limited block at water outlet 7
18, pillar 17 is fixedly installed arch block 20 at valve body 4, and two baffles 21 are symmetricly set on valve body 4, and arch block 20 supports
Between two baffles 21；It is fixedly installed rotator 22 far from 20 side of arch block on baffle 21, fixation is set on rotator 22
It is equipped with telescoping cylinder 23, piston rod one end of telescoping cylinder 23 is fixedly installed hairbrush 24；It is located at arch block 20 on pillar 17 and fixes
