Abstract
The utility model provides a butterfly valve, which comprises a valve body, a valve clack and a valve rod, wherein the valve body is provided with a shaft hole; the valve rod penetrates through the shaft hole and is fixedly connected with the valve clack; the valve body and the valve clack are matched to form an open or closed passage; a sealing ring is arranged between the valve body and the valve clack; and the valve clack is provided with a groove. The butterfly valve is characterized in that the groove is a dovetail groove, and the sealing ring is embedded in the dovetail groove. The device is simple in structure, convenient to use, low in cost, safe and reliable; and when the butterfly valve is opened under pressure, the sealing ring can be fixed in the groove of the valve clack.
Description
[technical field]
The utility model relates to a kind of butterfly valve, relates in particular to the butterfly valve that a kind of flap colludes groove.
[background technique]
Butterfly valve is Flap valve again, be a kind of modulating valve simple in structure, also can be used for the switch control of low pressure pipeline medium simultaneously, butterfly valve refers to that closure member (flap or butterfly plate) is disk, center on a kind of valve that valve shaft rotates to reach open and close, main rising cut off and throttling action on pipeline.Butterfly valve is applicable on the pipeline of carrying various corrosivity, non-corrosive fluids medium, is used for regulating and blocking flowing of medium.The key of the keying of butterfly valve is the sealing between valve body and the flap, and when having flowing medium in the pipeline, there is certain pressure in flowing medium to butterfly valve, so press off when opening when the butterfly valve band, seal ring is produced easily.
[model utility content]
The purpose of this utility model is to provide a kind of butterfly valve, so that when opening under butterfly valve band pressure condition, can make seal ring be fixed on flap and collude in the groove.
For reaching aforementioned purpose, a kind of butterfly valve, comprise valve body, flap and valve rod, offer axis hole on the described valve body, described valve rod is fixedlyed connected with described flap by described axis hole, is provided with seal ring between described valve body and the flap, and described flap is provided with and colludes groove, the described groove that colludes is dovetail groove, and described seal ring embeds in the dovetail groove.
According to an embodiment of the present utility model, the width of described dovetail groove increases gradually from opening to bottom surface.
According to an embodiment of the present utility model, described seal ring is O type circle.
According to an embodiment of the present utility model, the difference of the external diameter of described seal ring and the internal diameter of described seal ring is between described dovetail groove opening width and place, described dovetail groove bottom surface width.
The utility model beneficial effect: compared with prior art, a kind of butterfly valve, comprise valve body, flap and valve rod, offer axis hole on the described valve body, described valve rod passes described axis hole and described flap is fixedly connected, and described valve body cooperates the path that forms switching with described flap, be provided with seal ring between described valve body and the flap, described flap is provided with and colludes groove, it is characterized in that the described groove that colludes is dovetail groove, and described seal ring embeds in the dovetail groove.This device has simple in structure, and is easy to use, with low cost, safe and reliable, and can open under butterfly valve band pressure condition the time, can make seal ring be fixed on flap and collude in the groove.

Fig. 2 is the A portion enlarged diagram of a kind of butterfly valve of the utility model.
[embodiment]
Alleged " embodiment " or " embodiment " refers to be contained in special characteristic, structure or the characteristic at least one implementation of the utility model herein.Different local in this manual " in one embodiment " that occur not are all to refer to same embodiment, neither be independent or the embodiment mutually exclusive with other embodiments optionally.
See also shown in Figure 1ly, it shows the cross-sectional schematic of a kind of butterfly valve of the present utility model.As shown in Figure 1, a kind of butterfly valve, comprise valve body 1, flap 2 and valve rod 3, offer axis hole 4 on the valve body 1, valve rod 3 passes axis hole 4 and is fixedly connected with flap 2, and valve body 1 cooperates the path that forms switching with flap 2, be provided with seal ring 5 between valve body 1 and the flap 2, flap 2 is provided with and colludes groove, and colluding groove is dovetail groove 6, and seal ring 5 embeds in the dovetail groove 6.
See also shown in Figure 2ly, it shows the A portion enlarged diagram of a kind of butterfly valve of the utility model.As shown in Figure 2, dovetail groove 6 A/Fs to dovetail groove 6 bottom width increase gradually.
In an embodiment of the present utility model, seal ring 5 can also be O type circle.The difference of seal ring 5 external diameters and seal ring 5 internal diameters is preferably between dovetail groove 6 A/Fs and described dovetail groove 6 bottom width.
In an embodiment of the present utility model, the bar number of seal ring 5 can be set to a plurality of according to the thickness of flap 2 and valve body 1, and with the corresponding coupling of bar number of dovetail groove 6.
A kind of butterfly valve of the present utility model has simple in structurely, easy to use, with low cost, safe and reliable, and can open under butterfly valve band pressure condition the time, can make seal ring be fixed on flap and collude in the groove.
Above-mentioned explanation has fully disclosed embodiment of the present utility model.It is pointed out that and be familiar with the scope that any change that the person skilled in art does embodiment of the present utility model does not all break away from claims of the present utility model.Correspondingly, the scope of claim of the present utility model also is not limited only to previous embodiment.
