Described water sealing slice is on described water shutoff bar, described valve seat, described water sealing slice, described water sealing slice lid, described elastic corrugated Sealing, described fixed cover are arranged in described valve casing successively, described water shutoff bar is in described water shutoff rod aperture and energy is freely up and down, and described water shutoff head is above described control hole;
When there being current to enter, when described water shutoff bar moves up, due to the described water shutoff head of flexible effect moving, thus open described control hole, under the effect of hydraulic pressure described water sealing slice and described water shutoff bar together on move, thus open the described water outlet on described valve seat; When described water shutoff bar moves down, described water shutoff head is moved down, thus closes described control hole, under the effect of hydraulic pressure, described water sealing slice and described water shutoff bar together move down, thus close the described water outlet on described valve seat;
Close the improvement of spool as inner chamber of the present invention, its further feature is: also comprise needle, and described water sealing slice has covered needle hole;
Close the improvement of spool as inner chamber of the present invention, its further feature is: described valve casing and described valve seat are integrated.
The invention has the beneficial effects as follows:
Only need control spool top water shutoff bar gently moves up and down the unlatching or closedown that just can control outlet valve.

Embodiment
Consult Fig. 1 (a), Fig. 1 (b), valve casing 1 has water intake 2, water outlet 3;
Consult Fig. 2 (a), Fig. 2 (b), fixed cover 4 has water shutoff rod aperture 5;
Consult Fig. 3 (a), Fig. 3 (b), flexible corrugated sealing installation position 7, needle hole 8 on water sealing slice lid 6;
Consult Fig. 4 (a), Fig. 4 (b), water shutoff bar 10 has control hole 11, needle hole 8;
Consult Fig. 5 (a), Fig. 5 (b), water sealing slice 12 has and is communicated with aperture 13, wherein, water sealing slice 12 makes with colloid;
Consult Fig. 6, valve seat 14 has water intake 2, water outlet 3, seal groove 15;
Consult Figure 10, elastic corrugated Sealing 19 is made with colloid, above has water shutoff 20, water shutoff rod aperture 5;
Consult Fig. 1 (a) to Figure 11, water sealing slice 12 is arranged on water shutoff bar 10, connection aperture 13 is alignd with needle hole 8, valve seat insert 16 is installed in the seal groove 15 on valve seat 14; Valve seat 14, water sealing slice 12, water sealing slice lid 6, be arranged in valve casing 1 successively, alignd with the needle hole 8 on water shutoff bar 10 in needle hole 8 on water sealing slice lid 6, again needle 17 to be inserted needle hole 8 on water shutoff bar 10 from the needle hole 8 water sealing slice lid 6 and be communicated with in aperture 13, again elastic corrugated Sealing 19 is installed on the elastic corrugated Sealing installation position 7 on water sealing slice lid 6, again fixed cover 4 is fixed in the above, finally water shutoff bar 18 is installed in water shutoff rod aperture 5 from top to bottom;
Wherein, water intake 2 on valve casing 1 and water intake 2 section aligned on valve seat 14, water outlet 3 on valve casing 1 aligns with the water outlet 3 on valve seat 14, and above the control hole 11 of water shutoff 20 on water shutoff bar 10, water shutoff bar 18 can be freely up and down in water shutoff rod aperture 5.
Introduce the working procedure that inner chamber of the present invention closes spool below
Consult Figure 11, when water shutoff bar 18 moves down, water shutoff bar 18 pushes up water shutoff 20 and makes the stretching of the corrugated part of elastic corrugated Sealing 19 thus water shutoff 20 is moved down, thus close control hole 11, under the effect of hydraulic pressure, water sealing slice 12 and water shutoff bar 10 together move down, thus close the water outlet 3 on valve seat 14;
When water shutoff bar 18 moves up, due to flexible effect water shutoff 20 moving, thus open control hole 11, as shown in figure 12; Consult Figure 13, water sealing slice 12 and water shutoff bar 10 1 is the same moves under the effect of hydraulic pressure, and make behind top to water shutoff 20 water shutoff 20 again moves, thus open the water outlet 3 on valve seat 14, current flow out after water intake 2 flows through water outlet 3.
The basis of invention can make valve casing 1 and valve seat 14 are integrated, above-mentioned improvement is protection scope of the present invention.
