One locking swivel nut and valve gap screw togather, and compress adjusting screw; The outside of the adjusting screw below the locking swivel nut in the valve body is with polytetrafluoroethylene gasket;
Described valve gap and valve body screw togather.
Described heat responsive element has flap, and heat responsive element and flap are one.
The installation direction of described heat responsive element is perpendicular to the import and export direction of medium.
The slightly larger in diameter of described adjusting screw end in valve body is in the internal diameter of polytetrafluoroethylene gasket.
Described plug screw one end is an opening.
The phase-contact surface that described valve gap and valve body screw togather has gasket seal.
Described plug screw and valve body phase-contact surface have gasket seal.
Described adjusting screw is screwed in the locking swivel nut, is from up precession of hand of spiral.
Described gasket seal can be a teflon gasket.
The used polytetrafluoroethylene gasket material of the utility model is not influenced by medium temperature and is out of shape, and seals tighter.
The utility model compared with prior art, design rational in infrastructure, simple, compact structure, temperature control is accurate, safe, can online adjusting control temperature.The stroke that utilizes adjusting screw to change heat responsive element unlatching, throttle down comes the control temperature of control valve.The operating time is saved in the online adjusting of safety, increases work efficiency, and security seal is tight, really reaches energy-saving effect.
Below in conjunction with accompanying drawing structure of the present utility model and principle thereof are further elaborated.
