Summary of the invention

The purpose of this utility model is to improve at the deficiency of above-mentioned patent, and provides a kind of rational in infrastructure, fly valve easy to assembly.

Realize that the technological scheme that the purpose of this utility model is taked is that a kind of fly valve has valve body, valve rod, bowl-type valve plug; Valve body by valve port pipe and valve seat each other one form and both inner chambers communicate, it is just crossing that the axis of valve port pipe and valve seat is mutually; On the sidewall of valve seat, be respectively equipped with two chutes vertically; The both sides of valve rod are respectively equipped with handle, and the handle of valve rod is located in the set chute of valve seat and can slides vertically, and its improvement is: it also has end cap, and said end cap is mutually one by an end cap flange and a watt shape raised line and forms; Said watt of shape raised line is located in the valve seat, and the end cap flange is connected with the end face of valve seat; The bowl-type valve plug is connected with the mandrel tabling of valve rod; The bowl-type valve plug can with the close plug of the outlet of valve seat; The open-mouth end end face of bowl-type valve plug can connect with the end face of watt shape raised line of end cap; Two handles of valve rod are located in the chute of valve seat by the vacancy between two watts of shape raised lines of end cap respectively and stretch outside the sidewall of valve seat.

Can understand that by above given technological scheme the utility model is owing to be provided with end cap, and make its assembling become very convenient, thereby realize the purpose of this utility model.

The concise and to the point description of working condition of the present utility model is, when its actual use, the user is as long as be pressed on the end cap with thumb, makes on the handle of valve rod with 2 fingers simultaneously and lifts, and the bowl-type valve plug is opened, and the utility model promptly is in opening state; Unclamp finger, be connected to the bowl-type valve plug on watt shape raised line of end cap, reset under the effect of its deformation elastic force, the bowl-type valve plug is blocked the outlet of valve seat, and the utility model promptly is in closed condition.Can be understood that by the concise and to the point description of above operating mode structure of the present utility model is reasonably, assembling also is very easily.

The further improvement of the utility model point is:

Both sides at valve rod are respectively equipped with key vertically, are respectively equipped with keyway vertically in the inboard of watt shape raised line of end cap, and said key and keyway are slippery to be closed.Can understand by this further improved technological scheme, because the existence that said key cooperates with keyway can make the axial motion of valve rod more stable; And more effectively stoped the rotation of valve rod.

The inboard of the end cap flange of said end cap is provided with the outside of valve seat and overlaps near the valve identification of opening of configuration; Be provided with the tear seam that is connected by several tooth points between the end face of said identification cover and end cap flange; Said identification cover is provided with the tear seam that is connected by several tooth points vertically.Its purpose obviously is, whether whether identification bought drink packing bag/box and opened and drank when buying drink by the Consumer, perhaps pours in down a chimney drink in package bag/box and makes fake and forged drink foundation is provided.Tear tear seam and tear seam and take off the identification cover, can normally use the utility model.

More than after given technological scheme implemented, characteristics such as what the utility model had is rational in infrastructure, easy to assembly, practical with and the identification, the antiforge function that are had be conspicuous.
