4 outlet one end internal diameter of suction nozzle and with the sealing surface 401 formed sealing cooperation.By above-mentioned setting, hydraulic pressure is bigger, and first is close
Sealing effect between seal and suction nozzle is better, plays the role of preventing leakage.
The upper position-arresting flap 205 is equipped with guiding surface 207.Even if in this way, there is a small amount of offset, in guiding surface
207 and sealing surface 401 under the action of, it is also ensured that the first sealing ring and the sealing function between sealing surface 401, Yi Jimi
Sealing function between 4 outlet one end of packing and suction nozzle.
The suction nozzle 4 is connected by screw to the main body 1, and sealing is equipped between the suction nozzle 4 and the main body 1
Circle.
As in Figure 3-5, the water inlet pipe 104 is discharged one end end and is equipped with notch 105, when the hydraulic pressure of water inlet 101
When greater than certain value, the adverse current core 2 opens water inlet 101 under the action of water pressure and closes air inlet 102, the adverse current core 2 with
Go out to form the inlet channel into water inlet pipe 104 in notch 105 between water inlet pipe 104, the air inflow of inlet channel is less than air inlet
The air inflow of mouth 4.The setting of notch 105 is the small probability that the failure of adverse current core 2 causes 101 hydraulic pressure of water inlet excessive in order to prevent
Event.
Embodiment 2:
As shown in figure 3, a kind of automatic anti-siphon solenoid valve, the main body 1 are the connecting pipe of four ports, upper and lower two logical
Mouth is respectively air inlet 102 and water inlet 101, and two ports of two sides are water outlet 103, and water outlet 103 connects electromagnetism and rinses
Water inlet one end of valve 3, the structure in main body 1 are same as Example 1.
It can also be the connecting pipe of three ports with main body 1, the structure of embodiment 1 is connected to electromagnetic flushing valve by pipeline
