Closed: cold water, the holding time: 20 s no distortion, no hot water leakage location, the holding time: 20 s no deformation and no leakage Open: cold water, the holding time: 20 s no distortion, no hot water leakage location, the holding time: 20 s 4 no distortion, no leakage, torque test valve core (100% each) testing conditions: static pressure is zero, the gland nut torque: 8-12 n. m cold water to hot water rotary torque: 0.16-0.25 N.m context switches torque: 0.16-0.25 N.m 5, valve core conditions of life test: 20 + / - 1 ºC cold water temperature, hot water temperature of 65 + / - 1 ºC, the water pressure of 0.4 Mpa, switch 1.5
N.m torque test methods: starting from the middle closed position 0, after open water mouth closed, complete a switch action, that is, from 0 to 1 to 2, in the closed position to the cold water 3, turn on the switch to 4, 5 in the open position to the hot water position, delay for 5 seconds, turn to cold water position 6, delay for 5 seconds, close to the location 7, 8 in the closed position to hot water position and place in hot water to complete a switch action, that is, from 8 to 9 to 10, in the closed position to 11, 0 is returned to the original position.
At this point, to complete a ordered to test. Test result: no deformation, no leakage after 500000 times.on the moving valve, valve plates and the static valve fit each other, the static valve installed in the valve core and shell, also installed at the bottom of the static valve plates have tablet and gasket, described the static valve open, there are two relative water hole, move the valve opening is corresponding to the water hole water hole, described in turn on the core open hole with its central axis direction;
When turn rotating core, turning fork of the bottom of the core drive valve plate rotation, makes dynamic water hole on the valve plates and the static valve on the inlet hole is corresponding to each other and finally hole outflow in the history of water transfer from the core, this design is widely applied in the faucet outlet.
According to the movement way into rotary (45 °, 90 °, 180 °, 360 °), horizontally (radial, oriented).
In general can be divided into spherical shape (ball valves), cone (cock), round pie (butterfly valves and gate valves), dome type (globe valve and check valve) cylindrical (directional valve).
Pressure relief valves in the valve core is to realize the control of one of the main components.
Ceramic valve core, which include installation within the valve core and shell, the faucet valve core shell core plug have turn, turn the lower core through the fork card on the moving valve, valve plates and the static valve fit each other, the static valve installed in the valve core and shell, also installed at the bottom of the static valve plates have tablet and gasket, described the static valve open, there are two relative water hole, move the valve opening is corresponding to the water hole water hole.
Related research shows that the ceramic valve core has more than 500000 times after switch operation can still easy smooth operation and durable to use. Ceramic valve core ageing resistance, wear resistance, no need for maintenance, ensure the operation stability, save the maintenance cost and labor intensity and so on. At the same time, ageing resistance and wear resistance are also makes the service life of the ceramic valve core has gone far beyond the other service life of the valve core.
Ceramic materials tensile strength is high, the distortion, high temperature resistant, low temperature resistance, wear resistance, no corrosion features good sealing performance determines the ceramic material. Ceramic valve core makes the faucet has difficulty in leakage water droplets, achieved the purpose of environmental protection of water-saving.
When turn rotating core, turning fork of the bottom of the core drive valve plate rotation, makes dynamic water hole on the valve plates and the static valve on the inlet hole is corresponding to each other and finally hole outflow in the history of water transfer from the core, this design is widely applied in the faucet outlet.
The utility model discloses a ceramic valve core, it consists of static and ceramic dynamic piece of valve core and the shell of the gasket, static pieces, ceramic pieces, rubber spring coil loading and then loaded into the valve body, valve core shell with spring will its fixed, the external, suit the body open closed loop, with the top wire sticking ceramic piece of top wire, when opening and closing by dial ring spins ceramic piece of rotation.
