Further, described valve rod is body, and described valve rod is provided with suction port and air outlet, and described valve rod suction port is communicated with valve body influent stream mouth, and described valve rod air outlet is communicated with the valve gap air outlet, is provided with sealing plug with cooperating the valve rod suction port on the described guide rod.

Further, also be provided with the extra-air inlet that can cooperate with sealing plug with closure or unlatching on the described air leaving cover, the sealing plug that described valve rod passes on air leaving cover extra-air inlet and the guide rod is flexibly connected,

Further, also be provided with filter screen on the described valve body influent stream mouth.

By adopting the aforementioned techniques scheme, the beneficial effects of the utility model are: compare with existing composite exhaust valve, this composite exhaust valve has been set up miniature outlet valve at valve gap, the gas that produces in the water delivery process, often rise successively with the form of bubble and go forward side by side in the miniature outlet valve, when air rises to certain pressure, miniature outlet valve is opened Exhaust Gas, and close rapidly, and the ball float in the valve pocket need not done lifting exhaust action, miniature outlet valve can reduce the unsteady frequency of ball float, in the working life that has prolonged, also makes the better effects if of exhaust; Further, valve rod is hollow, and guide rod is provided with the sealing plug that is mated, and makes exhaust, air-breathing better effects if; Further, the position that cooperates with sealing plug on the air leaving cover also offers extra-air inlet, makes exhaust, air-breathing better effects if; Further, valve body influent stream mouth is provided with filter screen, can protect outlet valve, makes outlet valve stable, longer service life.

Description of drawings

Fig. 1 is the utility model embodiment's structural representation.

Fig. 2 is the use phase diagram that novel combined outlet valve stops a large amount of exhausts.

Embodiment

Now with embodiment the utility model is further specified by reference to the accompanying drawings.

With reference to figure 1, a kind of novel combined outlet valve of the present utility model, comprise tubular valve body 1, valve gap 2, valve rod 3, flap 4, described valve body 1 is provided with influent stream mouth 11, described valve gap 2 is located on the valve body 1, described valve gap 2 is provided with air outlet 21, described valve gap air outlet 21 is provided with air leaving cover 5, described air leaving cover 5 is provided with seal ring 6 with valve gap 2 joints, described air leaving cover 5 is provided with the suction port 51 that is communicated with valve body influent stream mouth 11, the air outlet 52 that is communicated with the valve gap air outlet, described valve rod 3 can be located in the air leaving cover air outlet 52 up or down, described flap 4 can with seal ring 6 clutches be arranged in and be positioned at air leaving cover 5 on the valve rod 3, described valve gap 2 belows are connected with connecting rod 71, described connecting rod 71 is hinged with guide rod 72, be connected with stainless steel floating ball 7 on the free end of described guide rod 72, described valve rod 3 passes air leaving cover 5 and is flexibly connected with guide rod 72, also be provided with miniature outlet valve 8 on the described valve gap 2, the suction port 81 of described miniature outlet valve 8 is communicated with the influent stream mouth 11 of valve body, the air outlet 82 of described miniature outlet valve 8 is communicated with atmosphere, also is provided with filter screen 9 on the described valve body influent stream mouth 11.
