Ring pads can be moved left and right along screw, when into during steam pore pressure force increase, holding water inlet pore pressure force is constant, mixed in cavity II
Hot water is flowed back by apopore II in cavity III under the action of steam pressure, and the hot water to flow back at this time can give ring pads certain
Pressure, the direction for making ring pads along screw axis move right a distance, and ring pads circular conical surface is right with inlet valve tubbiness convex inner walls
The gap at end becomes larger so that enters the volume increase of cold water in cavity II so that and the water temperature that apopore I flows out keeps stablizing,
When becoming smaller into steam pore pressure force, mixed hot water will not be flowed back by apopore II in cavity III in cavity II, ring pads
It is moved to the left under the action of II elastic force of spring, ring pads circular conical surface and the gap of inlet valve tubbiness convex inner walls right end become smaller, and lead to
It crosses apopore II and enters the volume of cold water in cavity II and become smaller so that apopore I flows out water temperature and keeps stablizing.
4th, the apopore I is equipped with location hole, is equipped with thermometer on the location hole, thermometer can detect in real time
The water temperature in water hole timely adjusts the inflow of cold water, adjusts temperature.
5th, the sealing ring uses polytetrafluoroethylene material, and polytetrafluoroethylene material stable chemical performance, thermal stability is good,
For cracking temperature at 400 DEG C or more, polytetrafluoroethylene material has anti-attrition, self lubricity.
6th, sealing ring is equipped between the left and right end cap and valve body, in the case where hydraulic pressure is higher, can preferably be ensured
The leakproofness of valve body prevents the hot water after steam or steam cold water mix from revealing, and scald accident occurs.
