Compression spring 17 is provided with, the upper end of compression spring 17 is connected with flange 15-1 lower ends, compression spring lower end and the upper table of positioning seat 16
Face is connected.The front end of limited block 14 and the lower end of locking button 15 are both provided with larger chamfering.Promote before guide rod 2, limited block 14 forward
The chamfering at end and the lower end chamfer contact of locking button 15, guide rod 2 readvances, and promotion locking button 15 is upward to move, until limited block 14 is complete
Entirely after locking button 15, locking button 15 recovers original position under the pulling force of compression spring and realizes locking to guide rod.
The use process of the present invention：
State first as shown in figs. 1 and 3, hot water pipeline 8 and the angle of cut of cold water pipes 9 are 180 °, and mixing duct is located at hot-water line
In the middle of road 8 and cold water pipes 9, groove connects hot water pipeline 8, cold water pipes 9 with mixing duct 10, and now hot water and cold water enter
Row is mixed and fed into mixing duct and used for daily hot water, now rotates clockwise in the small angle of guide rod, mixing duct 10
Hot water amount be more than cool water quantity, rotate counterclockwise hot water amount in the small angle of guide rod, mixing duct 10 and be less than cool water quantity, with
Water temperature in this regulation mixing duct 10；Guide rod 2 rotates 180 °, as shown in figure 4, hot water pipeline 8 is connected with cold water pipes 9 in upper
Water state；Guide rod 2 is promoted to advance small distance, now cold water and hot water enter the water of hot water pipeline 8 and cold water pipes 9 all
Reduce, water size in adjustment mixing duct 10；Continue to press on guide rod 2, as shown in Fig. 2 ball sealer 12 along passage I 6 and under
Waterpipe 5 rises and eventually settled under the filter plate of the upper end of sewer pipe 5, and hot water is sent back in water tank, and limited block 14 is blocked
Button 15 is blocked, and realizes the closing of valve.As shown in figure 1, guide rod 2 is pulled back, in the negative of the own wt of ball sealer 12 and annular seal space 4
The bottom of passage I 6 is fallen under the lower meeting of ball sealer 12 of pressure effect, hot water all enters back into hot water pipeline 8 by passage I 6 so that valve
Door is normally used.
