Anti-siphoning-pressure one-way valve

Abstract

An anti-siphoning-pressure one-way valve is characterized by comprising a nozzle connector and a spray rod connector. One end of the nozzle connector is connected with a nozzle, and the other end of the nozzle connector is internally provided with a water outflow base which is provided with an outflow duct and an exhaust hole. The water outflow base is provided with a cavity, and the exhaust hole is communicated with the cavity. One end of the cavity of the water outflow base is provided with an opening which is sleeved with a silicone membrane. The silicone membrane is provided with a through hole. A membrane holder disposed in the through hole is provided with a spring holder baffle and a membrane baffle. The membrane baffle contacts with one side of the silicone membrane. The silicone membrane is provided with a spring holder on one side of the cavity. The spring holder baffle contacts with the spring holder. A screw penetrates the spring holder baffle and is fixed to the membrane holder. Springs are disposed between the spring holder and the inner wall of the cavity of the water outflow base. The spray rod connector is provided with an internal seal ring which contacts with the silicone membrane. The spray rod connector is also provided with an internal ring groove outside the seal ring. The spray rod connector is also provided with an internal stopper and an internal flow groove outside the ring groove, the stopper and the flow groove are separated, and the flow groove is communicated with an outflow groove of the outflow block.

Description

technical field [0001] The present invention relates to a one-way valve, in particular to an anti-siphon pressurized one-way valve. Background technique [0002] In the prior art, when the sprayer and various liquids are working, the liquid in the liquid storage tank is continuously sprayed out from the nozzle through the water pump, and when the water pump is turned off, part of the liquid in the liquid storage tank will still flow out under the action of the siphon. resulting in waste. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the prior art, and to provide an anti-siphon device that prevents the liquid in the liquid storage tank from flowing out under the action of siphon after the sprayer and various liquids stop working, and can prevent backflow. Pressurized check valve. [0004] The technical scheme of the anti-siphon pressurized one-way valve of the present invention is: it is characterized in that it...
