In prior art, in the Chinese patent prospectus that is CN201420089669.8 at application number, a kind of butterfly valve is disclosed, it comprises handle, valve shaft and valve body, the top of valve body is provided with boss, and boss is provided with lug, and the top of valve body is also provided with stiffening rib, the middle part of stiffening rib is provided with arc notch, the lower end of valve body is provided with arc bump, and arc bump is provided with two symmetrical long waist shaped holes, and long waist shaped is provided with positioning hole between hole.This butterfly valve has strengthened the intensity on valve body top by the stiffening rib with arc notch arranging, strengthen the location of valve body and fixed by the arc bump and the positioning block that are provided with long waist shaped hole, when pipe laying, normally the pipeline welding at two ends is fixed on flange plate, flange plate is fixed in the attachment hole of positioning block on arc bump and connecting base by bolt again, only by fastening piece, valve is fixed on pipeline, it is not firm to connect, and the center line of valve and pipeline is difficult to be aligned on same straight line, need to repeatedly adjust, be inconvenient to install.
Model utility content
The deficiency existing for prior art, the purpose of this utility model is to provide a kind of fast fitted lining fluorine of reducing wafer type butterfly valve of Rapid pipe installation.
For achieving the above object, the utility model provides following technological scheme: the fast fitted lining fluorine of a kind of reducing wafer type butterfly valve, include flap, valve body, valve rod, gland, described valve body is circular shape, described flap is arranged on described annular valve body hollow portion, on described valve body circular arc, offer through hole, described flap is disc shape and is connected with open tubular column, described valve rod is successively through described through hole and described open tubular column, described flap is fixed on described valve body, on one end of described valve body, be evenly provided with support, the other end is provided with groove with respect to support portions, in described groove, be provided with swing bolt.
Adopt the fast fitted lining fluorine of the reducing wafer type butterfly valve of this structure, in the time that pipeline construction is on support, by swing bolt, pipeline is more firmly linked together with valve, reach the effect of quick assembling, make valve relative with pipeline center, prevent from leaking, simultaneously, when valve goes wrong need to take apart time, only need twisting swing bolt just detachable, make to overhaul convenient.
As preferably: the inwall of described valve body is inlaid with anticorrosive coat, and the outer surface of described flap scribbles anticorrosive coat.
The fast fitted lining fluorine of the reducing wafer type butterfly valve that adopts this structure, anticorrosive coat is teflon, and valve antiseptic power is strengthened, and possesses very high heat-resisting cold tolerance simultaneously, friction factor is low, has promoted the working life of valve, has prevented water leakage phenomenon.
As improvement: the anticorrosive coat of described valve interior wall is ring, and offers annular groove on the arc shaped surface of described ring anticorrosive coat, and the inwall of described annular groove and described valve body fits.
Adopt the fast fitted lining fluorine of the reducing wafer type butterfly valve of this structure, anticorrosive coat is fixed on to the inwall of valve body, prevent the water leakage phenomenon that the interior dielectric corrosion circulating of valve body causes.
Compared with prior art, the utility model has the advantage of: by be provided with groove on valve body, and be provided with therein the structure of swing bolt, thereby solve only by fastening piece, valve being fixed on pipeline of existing in prior art, it is not firm to connect, and the center line of valve and pipeline is difficult to be aligned on same straight line, the seepy question causing, by the direct fixing tube of swing bolt, situation about need to repeatedly adjust while having solved pipeline and valve installation, prevented water leakage phenomenon, dismounting is simultaneously quick, convenient maintenance pipe fitting or replacing valve.
