Working principle of the present invention is as follows:
Dextrorotation rotating valve rod 6, valve rod 6 down moves under the screw thread guiding of valve gap 5, and liner 4 also moves in the same way under guide rod 10 with guide cavity 7 location fit, and makes to seal between epithelium 3 and valve port 12 by the stressed transmission of liner 4, valve closing.
Be rotated counterclockwise valve rod 6, valve rod 6 rises to highest order under the screw thread guiding of valve gap 5, and valve place opening state, as shown in the state of Fig. 1 and Fig. 2.If now user is without water: the hydraulic pressure in the hydraulic pressure in inlet channel 1 and epithelium 3 epicoele and in water outlet 13 is equal, under magnetic attraction force between pad insert 8 and valve rod inserts 9 adds the effect of epithelial membrane 3, liner 4, guide rod 10 and pad insert 8 four self gravitation, sealing state (as shown in Figure 1) is between epithelium 3 and valve port 12, pressure surge between effective partition inlet channel 1 and water outlet 13, reaches and prevents the water meter be connected with water outlet 13 from producing rotation.Under the magnetic attraction force between pad insert 8 and valve rod inserts 9 adds the effect of epithelial membrane 3, liner 4, guide rod 10 and pad insert 8 four self gravitation, sealing state is between epithelium 3 and valve port 12, so when inlet channel 1 place fluid pressure reduces, liquid in epithelium 3 epicoele and in water outlet 13 cannot be back to inlet channel 1, reaches effective non-return.If the now just conventional water of user: because the liquid in water outlet 13 is by relief hole 11 and the liquid communication in epithelium 3 epicoele, therefore when user just commonly uses water, fluid pressure in fluid pressure in water outlet 13 and epithelium 3 epicoele synchronously declines, the pressure reduction that epithelium about 3 the is formed magnetic attraction force overcome between pad insert 8 and valve rod inserts 9 adds the gravity of epithelial membrane 3, liner 4, guide rod 10 and pad insert 8 four self, epithelium 3 is up pushed away together with liner 4, so valve open (as shown in Figure 2).Valve is once open, magnetic attraction force between pad insert 8 and valve rod inserts 9 just disappears (along with the spacing between pad insert 8 and valve rod inserts 9 increases, magnetic adsorptive power each other just reduces gradually, until disappear), the gravity that the liquid in inlet channel 1 only needs definite value to overcome epithelium 3, liner 4, guide rod 10 and pad insert 8 four self add epithelial membrane 3 rise after own form be out of shape the reducing power produced.Breach general safety check utilize spring force seal after, the liquid passed through in valve not only will overcome fixing local resistance itself, also to overcome the resistance becoming the spring force of quadratic relationship to cause with valve opening degree simultaneously, effectively reduce the loss of head that liquid stream produces through valve, reach energy saving.If user's water clock leaks: develop from the manufacture of water meter itself, its accuracy of manufacturing undeniable and design sensitivity more and more higher, so by the restriction of the factors such as watermeter design principle and manufacture cost, user's water clock water and phenomenon that water meter does not count still exists.The present invention also has good inhibitory action to water meter water clock water phenomenon, it realizes principle: when user's water clock water, water outlet 13 reduces gradually with the hydraulic pressure in epithelium 3 epicoele and the water meter be connected below and pipeline, As time goes on, the pressure reduction of epithelium about 3 also can increase gradually, once this pressure reduction reaches the magnetic attraction force that can overcome between pad insert 8 and valve rod inserts 9 add epithelial membrane 3, liner 4, the gravity of guide rod 10 and pad insert 8 four self, epithelium 3 pushes away suddenly together with liner 4, valve is opened instantaneously, now valve has one liquid to flow through suddenly between epithelium 3 and valve port 12, rapidly valve is entered, pressure balance in water outlet, and this burst of water impact acts on water meter, make water meter instantaneous between rotate metering, this phenomenon moves in circles in whole water clock water utilizing process, reach the effective suppression to water meter water clock water phenomenon.Breach general safety check can not produce stressed sudden change because of spring force thus effectively cannot suppress the phenomenon of water meter water clock water.
