Rubber gasket is equipped with in described blocking-up cap bottom, and blocking-up cap top is installed in the electronic plug, and the top of blocking cap simultaneously also has a groove, dress O shape circle II in the groove; Described blocking-up cap outer rim has a circle flange, depends on the valve interior wall location all around.
Adorn a return spring in the described blocking-up cap, the return spring bottom is stuck in the valve courage groove, and top withstands on the inner roof wall of blocking-up cap.
Described electronic plug is provided with a plurality of O shape circle I at the guide rod perforating position.
The utility model is made up of valve body, valve courage, blocking-up cap, electronic plug, guide rod, the several critical pieces of electric actuator.Blocking-up cap bottom is equipped with rubber gasket and is used for blocking the import current, plays seal action, and a groove is arranged at blocking-up cap top, dress O shape circle I is used for cutting off the current in two chambeies in the groove, and described blocking-up cap outer rim has a circle flange, depend on the valve interior wall location all around, the balance that keeps it moving up and down.Adorn a return spring in the blocking-up cap, the bottom is stuck in the valve courage groove, and top withstands on the inner roof wall of blocking-up cap, and return spring can provide certain tight power of giving, and is used for the blocking-up crown is opened.Be contained in the plug inner chamber behind the cover upper O-shape ring I of blocking-up cap top, guide rod withstands on the top of blocking-up cap, is used for transmitting the pressure of electric actuator.The electric actuator of outer dress has energising opens, and outage can provide certain pressure, and certain stroke can be arranged.
The beneficial effects of the utility model are: easy for installation, simple in structure, take up room little, can effectively satisfy engineering and use, be convenient to project installation, can save manpower, save cost.

Wherein, 1. electric actuator, 2.O shape circle I, 3. electronic plug, 4.O shape circle II, 5. blocking-up cap, 6. guide rod, 7. valve body, 8. return spring, 9. rubber gasket, 10. valve courage, 11. fens grommet type seals.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
Among Fig. 1, valve body 7 is a Y shape, and the water intake of its bottom and water outlet are point-blank.Valve courage 10 and blocking-up cap 5 are installed in the inclined hole.Should also be connected with external electric actuator 1 by electronic plug 3 by end simultaneously, the guide rod 6 of electric actuator 1 passes electronic plug 3 and withstands on and block on the cap 5, and electronic plug 3 is provided with a plurality of O shapes at guide rod 6 perforating positions and encloses I2.Install in the electronic plug 3 on blocking-up cap 5 tops, also the position also is that O shape circle II4 is arranged simultaneously, blocking-up cap 5 outer rims have a circle flange, depend on valve body 7 inwalls location all around, the lower end of blocking-up cap 5 then is provided with rubber gasket 9, also adorn a return spring 8 in the blocking-up cap 5, return spring 8 bottoms are stuck in valve courage 10 grooves, and top withstands on the inner roof wall of blocking-up cap 5.The valve courage has for 10 times branch grommet type seal 11 that valve body 7 is divided into two pressure chambers.
Working procedure of the present utility model is:
The water outlet (right side) of water intake of valve body 7 (left side) and valve body 7 is connected on respectively on pipeline intake pipe and the return pipe, and under the effect of pipe-line system, there is a unsettled pressure difference in the valve body two ends.As Fig. 1, when valve body was in opening state, current through the bottom of blocking-up cap 5, passed valve courage 10 by water intake then, flow out from water outlet.The effect of valve courage 10 is to remain on constant that the water yield flows in the unstable pressure differential range.
When opening state, electric actuator 1 is in "on" position, and pressure is not provided, and under the effect of the rebounding force of return spring 8, jack-up blocking-up cap 5 and guide rod 6 can pass through current from the bottom of blocking-up cap 5.The purpose of one aperture is arranged at the top of blocking-up cap 5 is in order to keep the pressure balance at its two ends, not to be subjected to the pressure of water.The effect of O shape circle II4 on the blocking-up cap 5 is sealing, does not allow the water of import enter the epicoele of blocking cap 5, avoids destroying the pressure at blocking-up cap 5 two ends.
When this pipeline does not need to supply water, the moving final controlling element 1 of disconnected power down, electric actuator 1 can provide a downward pressure gradually, and pressure is passed to blocking-up cap 5 by guide rod 6, and blocking-up cap 5 overcomes the active force of return spring 8 and the frictional force of O shape circle II4 and electronic plug 3 moves down, contact with valve courage 10 closely until rubber gasket 9, play seal action, like this, current just are cut off, reach the purpose that pipeline is cut off the water, as Fig. 2.When pipeline need resume water supply, only need to give electric actuator 1 power supply, electric actuator 1 does not provide pressure, and its pressure head is also regained, and under the active force of return spring 8, blocking-up cap 5 and guide rod 6 are returned to Fig. 1 state again.
