On above-mentioned valve body, the water management passage can be arranged.Above-mentioned water management passage can be on the pairing valve body of water intake.Above-mentioned epicoele inlet can be connected by two-position three way control valve and water pipe.Above-mentioned epicoele inlet can be connected by two-position three way control valve and water management passage.Above-mentioned two-position three way control valve can be two-position three way manual ball valve or manual stopcock of two-position three way or two-position three way magnetic valve.On above-mentioned piston, can be set with seal ring.Can be connected to waste pipe on the above-mentioned drain opening.
The utlity model has following advantage: but fast opening and closing, and control mode is matched nimbly and freely, has effectively solved the problem of water inlet water, has resistance to frost, is specially adapted to the last water control valve in winter.
Four, description of drawings:
Accompanying drawing 1 is for the master of the utility model most preferred embodiment looks the sectional structure schematic representation, and accompanying drawing 2 is a fundamental diagram of the present utility model; Coding in the accompanying drawing is respectively: 1 is valve body, and 2 is piston upper chamber, and 3 is the piston cavity of resorption, 4 is piston rod, and 5 is the upper and lower cavity through hole, and 6 is piston, 7 is the valve plug pad, and 8 is the epicoele inlet, and 9 is drain opening, 10 is water intake, and 11 is water outlet, and 12 is the water management passage, 13 is the two-position three way control valve, and 14 is water pipe, and 15 is water inlet, 16 is seal ring, and 17 is waste pipe.
Five, embodiment:
The utility model is not subjected to following embodiment's restriction, can determine concrete mode of execution according to the technical solution of the utility model and actual demand.
As shown in Figure 1, upward in the valve body 1 of water waterpower valve piston upper chamber 2 is arranged, piston cavity of resorption 3, piston rod 4 and upper and lower cavity through hole 5, the piston 6 that can move up and down is housed in piston upper chamber 2, one end of piston rod 4 is fixed on the piston 6, piston rod 4 passes upper and lower cavity through hole 5 back its other ends in piston cavity of resorption 3 and is fixed with valve plug pad 7, on the pairing valve body 1 in piston 6 outer ends epicoele inlet 8 is arranged, on piston rod 4 pairing valve bodies 1, drain opening 9 is arranged, on the valve plug pad 7 pairing valve bodies 1 water intake 10 is arranged, on the valve body 1 of piston cavity of resorption 3, water outlet 11 is arranged, water intake 10 can be closed after valve plug pad 7 moves down, drain opening 9 can be closed after valve plug pad 7 moves up.During control, the logical or pass of band press liquid by control epicoele inlet 8, move or move down on the realization piston 6, reach and close or open water intake 10, thereby the control that realization is cut off the water supply or supplied water from water outlet 11, residuary waters in the water inlet 15 that is connect with water outlet 11 in the valve body 1 when cutting off the water supply can be discharged from drain opening 9, thereby has antifreezing effect in the winter time.
For the ease of installing and control, shown in attached Fig. 1 and 2, water management passage 12 is preferably arranged on valve body 1, and water management passage 12 can be on water intake 10 pairing valve bodies 1, and epicoele inlet 8 is connected by two-position three way control valve 13 and water management passage 12, but epicoele inlet 8 also can directly be connected by two-position three way control valve 13 and water pipe 14, wherein, the two-position three way control valve can adopt two-position three way manual ball valve or manual stopcock of two-position three way or two-position three way magnetic valve, can realize telecontrol when the two-position three way control valve adopts two-position three way magnetic valve.
As shown in Figure 1, on piston 6, preferably be set with seal ring 16, so that play sealing effect better; As shown in Figure 2, on drain opening 9, preferably be connected to waste pipe 17, be beneficial to draining.
