Operation principle：As shown in Fig. 2, Fig. 2 is of the invention initial or spool status diagram when closing valve that is delayed, Product Assembly
After the completion, hydraulic cylinder 10 has been filled with hydraulic oil, and spool state is when valve is closed in initial or delay：Initial reset at resetting spring 31
State, oil cylinder piston 9 are in 10 upper end of hydraulic cylinder, and the big portion of hydraulic oil is in lower shoe cream room 30, lower limit at time-delay mechanism, tightly
Water stop valve core is pressed, closed state at spool.
As shown in figure 3, Fig. 3 is the present invention when being turned off manually or resetting spool status diagram, rotates clockwise rotary
Vertical lifting mechanism is to lower limit, and time-delay mechanism is pulled to lower limit, and spool enters reset state.During this, oil cylinder is lived
Plug 9 moves down, and resetting spring 31 is compressed, and damping steel ball 11 pushes away piston via 12 by forward direction, and choked flow spring 37 is compressed, hydraulic pressure
Oil flows to rapidly through piston via 12, oil inlet via 8 from lower shoe cream room 30 and goes up shoe cream room 33, after the completion of process, choked flow spring 37
It resets, piston via 12 is damped steel ball 11 and blocks, and oil cylinder piston 9 is in 10 lower end of hydraulic cylinder, presses water stop valve core, spool
Still locate closed state.
As shown in figure 4, spool status diagram when Fig. 4 is present invention unlatching, rotates rotary vertical conveyor counterclockwise
Structure is to upper limit, 9 upward stress of oil cylinder piston, and damping steel ball 11 is acted on by buffer brake, and piston via 12 is by tight closing, only
There is a small amount of hydraulic oil to flow to lower shoe cream room 30 from upper shoe cream room 33 from through oil return ditch 92, oil cylinder piston 9 is with time-delay mechanism's entirety quilt
A high position is drawn high, spool enters opening, if at this point, rotate clockwise rotary vertical lifting mechanism to lower limit, can close
Valve closing core simultaneously enters reset state, and spool state is as shown in Figure 3.
Fig. 5 is that the present invention is implemented on the structure diagram of tap, automatic delay function process：The present invention is assemblied in water
Tap main body 41 is sealed by body seal circle 292, and tap is mounted on water channel, counterclockwise the rotary vertical lift of rotation
Mechanism is to upper limit, 9 upward stress of oil cylinder piston, and damping steel ball 11 is acted on by buffer brake, piston via 12 by tight closing,
Oil cylinder piston 9 is integrally pulled up to a high position with time-delay mechanism, and spool enters opening, and water flows through water tap water inlet 42, valve
Core water inlet 20, spool water outlet 22 are exported from faucet outlet 43, at this point, hydraulic cylinder 10 is detached from lower limit, reset bullet
Spring 31 starts slow release, and hydraulic oil slowly flows to lower shoe cream room 30 from upper shoe cream room 33 through oil return ditch 92, due to revolving counterclockwise
It is motionless to rotate rotatable vertical lifting mechanism and oil cylinder piston 9, and 31 reseting procedure of resetting spring can only be with hydraulic cylinder 10
It moving down, after a period of time, the downward shoe cream room 30 of upper 33 hydraulic oil basic flow of shoe cream room, hydraulic cylinder 10 reaches lower limit,
Resetting spring 31 resets, and flow is automatically closed, and water valve core state is as shown in Figure 2.
Above-described is only the preferred embodiments of the present invention.It should be pointed out that the ordinary skill for this field
For personnel, without departing from the principles of the present invention, several improvement and modification can also be made, this is also considered as the present invention's
Protection domain.
