Description
Technical field
The present invention relates to piping attachment technical field, particularly relate to Flap valve.
Background technique
Butterfly valve is Flap valve again, is the simple modulating valve of a kind of structure, also can be used for the mode of the switch control rule of low pressure pipeline medium simultaneously.Valve butterfly valve in work refers to that closure member is disk, rotate a kind of valve reaching open and close around valve shaft, valve can be used for the flowing controlling all kinds fluids such as air, water, steam, various Korrosionsmedium, mud, oil product, liquid metal and radiating medium.On pipeline, main rising is cut off and throttling action.Butterfly valve open-shut device is a discoidal butterfly plate, rotates in valve body around the axis of himself, thus reaches the object opening and closing or regulate.But the many dirt of the work under bad environment residing for butterfly valve, when valve body dust accretion is too much, can cause opened butterfly valve very to be required great effort.
Summary of the invention
The technical problems to be solved in the utility model is: existing Flap valve, because the many dirt of work under bad environment, when valve body dust accretion is too much, can causes opening Flap valve and very require great effort.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of Flap valve, comprise valve body, valve rod and flap, described valve stem top connects rotating handles, bottom is inserted in valve body, and connect drive flap rotating open-close, the joint of valve rod and valve body is provided with the circular groove of indent, valve body is put for card, also be socketed with top seal circle and bottom sealing ring in described circular groove, top seal circle and bottom sealing ring fit respectively circular groove upper and lower surface and fold up between circular groove and valve body.
The utility model beneficial effect is: structure is simple, puts valve body, the joint sealability of valve rod and valve body is strengthened greatly owing to arranging circular groove card, arrange seal ring again to carry out pad and put fixing, further enhancing the sealing of joint, stop dust and enter, be convenient to open.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
Embodiment
In order to understand the utility model better, illustrate content of the present utility model further below in conjunction with example, but content of the present utility model is not only confined to the following examples.
The utility model comprises valve body, valve rod and flap, described valve stem top connects rotating handles, bottom is inserted in valve body, and connect drive flap rotating open-close, the joint of valve rod and valve body is provided with the circular groove 1 of indent, put valve body 2 for card, in described circular groove 1, be also socketed with top seal circle 3 and bottom sealing ring 4, top seal circle 3 and bottom sealing ring 4 fit respectively circular groove 1 upper and lower surface and fold up between circular groove 1 and valve body 2.
Put valve body 2 owing to arranging circular groove 1 card, the joint sealability of valve rod and valve body 2 is strengthened greatly, then seal ring is set carries out pad and put fixing, further enhancing the sealing of joint, stop dust and enter, be convenient to open.
