Description
Technical field
The utility model relates to a kind of Pneumatic butterfly valve.
Background technique
The traditional, pneumatic butterfly valve, comprise Pneumatic actuator, described Pneumatic actuator inside is provided with the piston control unit, be provided with valve on Pneumatic actuator, described valve body connects the bottom that is arranged on described Pneumatic actuator, and its inside is provided with butterfly plate and valve rod, and the upper end of described valve rod is connected with described piston control unit, the bottom of described valve rod is connected with described butterfly plate by valve shaft, between described Pneumatic actuator and described valve body, is connected with support.The defective tightness that is connected of the valve of this Pneumatic butterfly valve and outside air pump, easily come off or leak gas.
The model utility content
In view of the deficiency that background technique exists, technical problem to be solved in the utility model is to provide a kind of Pneumatic butterfly valve, this Pneumatic butterfly valve valve tightr with being connected of outside air pump.
The utility model takes following technological scheme to complete: comprise Pneumatic actuator, described Pneumatic actuator inside is provided with the piston control unit, be provided with valve on Pneumatic actuator, valve comprises patchhole, described valve body connects the bottom that is arranged on described Pneumatic actuator, its inside is provided with butterfly plate and valve rod, the upper end of described valve rod is connected with described piston control unit, the bottom of described valve rod is connected with described butterfly plate by valve shaft, be connected with support between described Pneumatic actuator and described valve body, be provided with tapered plugging section and tapped threaded joints in patchhole, tapered plugging section end is with suction port, be lined with elastic insert on tapered plugging section sidewall, described valve disposes for importing the bayonet end of air pump gas, bayonet end comprises the externally threaded attachment post of being with of tapered front end and rear side, described tapered front end is with air outlet.
In the utility model, the valve of Pneumatic butterfly valve inserts in the hole with tapered plugging section and threaded joints, when the bayonet end with its coupling inserts, the tapered front end sleeve of bayonet end is as in tapered plugging section, due to tapered plugging, section is lined with elastic insert, can make both sleeves tightr, and the threaded joints interior with patchhole with externally threaded attachment post at bayonet end rear portion is threaded, both formation not only firmly but also the annexation of sealing, thereby can effectively prevent that the conduit bayonet end of air pump and valve cooperation place from coming off or leaking gas.
