Abstract
The utility model relates to butterfly valve technical field, the two eccentric flexible sealing butterfly valve of especially a kind of flange-type.The two eccentric flexible sealing butterfly valve of this flange-type, there is valve body, valve gap and valve rod, described valve stem casing is provided with butterfly plate, the drive unit of actuate valve stem is provided with above valve body, described butterfly plate is set for the eccentric, be arranged with Upper shaft sleeve and Lower shaft sleeve between described valve body and valve rod, be provided with packing layer above Upper shaft sleeve, described packing layer is positioned at below valve gap; Described valve body is provided with the seal ring of oblique cone structure at inwall.The utility model structure is simple, reasonable in design, butterfly valve is easy to operate, time saving and energy saving, butterfly plate eccentric setting, the unnecessary excessive compression between butterfly plate and valve body, scraping phenomenon can be eliminated significantly, alleviate and open resistance apart from, working life of reducing wearing and tearing, improve butterfly valve, improve the sealability of butterfly valve simultaneously.
Description
Technical field
The utility model relates to butterfly valve technical field, the two eccentric flexible sealing butterfly valve of especially a kind of flange-type be applicable on the liquid mediums such as high temperature, high pressure, inflammable, deep-etching or gas medium delivery line.
Background technique
Modulating valve has another name called control valve, in industrial automation process control field, by accepting the control signal that regulation unit exports, removes by power operation the final control unit changing the process parameters such as rate-of flow, pressure, temperature, liquid level.As the one of modulating valve, traditional butterfly valve structure is complicated, complex operation, installs trouble, and poor sealing performance, easy senile abrasion, working life is short, easily causes leakage to cause security incident occurs.
Model utility content
The technical problems to be solved in the utility model is: overcome the deficiency in prior art, provides a kind of structure simple, the butterfly valve of good seal performance.
The utility model solves the technological scheme that its technical problem adopts: the two eccentric flexible sealing butterfly valve of a kind of flange-type, there is valve body, valve gap and valve rod, described valve stem casing is provided with butterfly plate, the drive unit of actuate valve stem is provided with above valve body, described butterfly plate is set for the eccentric, butterfly plate is made up of large butterfly plate and little butterfly plate, and described little butterfly plate is fixedly connected with pressing plate;
Be arranged with Upper shaft sleeve and Lower shaft sleeve between described valve body and valve rod, be provided with packing layer above Upper shaft sleeve, described packing layer is positioned at below valve gap; Described valve body is provided with the seal ring of oblique cone structure at inwall, and seal ring is positioned at little butterfly plate side.
Further, described valve body is shaping is provided with flange, and flange is provided with mounting hole, can well be connected with other pipe components.
Further, described little butterfly plate is fixedly connected with pressing plate by pressing plate fixing bolt.
Further, described drive unit is provided with handwheel.
Further, described seal ring is nitrile butadiene rubber seal ring or teflin ring, improves the sealability of butterfly valve.
The beneficial effects of the utility model are: the utility model structure is simple, reasonable in design, be provided with drive unit, make butterfly valve easy to operate, time saving and energy saving, butterfly plate eccentric setting, the unnecessary excessive compression between butterfly plate and valve body, scraping phenomenon can be eliminated significantly, alleviate and open resistance apart from, working life of reducing wearing and tearing, improve butterfly valve, meanwhile, valve body is provided with seal ring and packing layer, more improves the sealability of butterfly valve.
Accompanying drawing explanation
