Abstract
The utility model provides a kind of pressure-relief type butterfly valve, comprise valve body, valve rod and flap, described valve rod is positioned at valve body, and connect drive flap rotating open-close, described flap comprises two the semicircular lobe bodies in left and right, and the straight flange of described two lobe bodies is hinged and right lobe body is provided with relief hole, and the utility model beneficial effect is: structure is simple, by flap is divided into two-part, achieve the function that branch opens; And relief hole is set on right lobe body, the function enabling flap realize first pressure release to open again, thus reduce the pressure that butterfly valve opens, be convenient to open.
Description
Technical field
The present invention relates to piping attachment technical field, particularly relate to butterfly 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 working environment residing for butterfly valve is mostly comparatively severe, the pressure medium of such as many dirt, high temperature, circulation is comparatively large, medium has corrosivity etc., and the Dimensions of butterfly valve becomes large increasingly, thus opened butterfly valve is very required great effort.
Summary of the invention
The technical problems to be solved in the utility model is: existing butterfly valve, because working environment is mostly comparatively severe, is opened and very required great effort.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of pressure-relief type butterfly valve, comprise valve body, valve rod and flap, described valve rod is positioned at valve body, and connect drive flap rotating open-close, described flap comprises two the semicircular lobe bodies in left and right, and the straight flange of described two lobe bodies is hinged and right lobe body is provided with relief hole.
The utility model beneficial effect is: structure is simple, by flap is divided into two-part, achieves the function that branch opens; And relief hole is set on right lobe body, the function enabling flap realize first pressure release to open again, thus reduce the pressure that butterfly valve opens, 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, and described valve rod is positioned at valve body, and connects drive flap rotating open-close, and described flap comprises left lobe body 1 and right lobe body 2, and the straight flange of described two lobe bodies is hinged and right lobe body is provided with relief hole 3.
The utility model is combined into complete circular flap by left lobe body 1 together with right lobe body 2, because flap has been divided into two parts, therefore in the process of opening, first valve rod drives a side lobe body to rotate, and another one lobe body will delayed a little rotation, thus achieve the function that branch opens; And the relief hole 3 that right lobe body 2 is arranged, the function enabling flap realize first pressure release to open again, thus the pressure reducing that butterfly valve opens, be convenient to open.
Claims (1)
1. a pressure-relief type butterfly valve, comprise valve body, valve rod and flap, described valve rod is positioned at valve body, and connects drive flap rotating open-close, it is characterized in that: described flap comprises two the semicircular lobe bodies in left and right, and the straight flange of described two lobe bodies is hinged and right lobe body is provided with relief hole.
