Can a breathing valve be installed on a pipeline to prevent siphoning?

No, what if it’s full of water? There are special valves for breaking the siphon effect – why not use them?

Excuse me, sir, what type of valve is specifically used to break siphoning? ? ? Some people say that a check valve can be installed as a valve to prevent siphoning; I wonder if that’s feasible ?

I don’t know, but isn’t there a siphon break valve? A Siphon Breaker Valve is a type of safety valve. Installed above the hump (the highest point) of the siphonic water conveyance pipeline, it acts as a rapid gate for the siphonic outlet pipe. When negative pressure is generated in the main pipeline and there is a risk of backflow of the medium, the siphon should be disconnected promptly to ensure the safety of the pump valves and equipment. Design structure and functions: The structure of the siphon failure valve can be divided into a water chamber, an air chamber, primary and secondary electromagnetic operating mechanisms, and an electrical control box. The water chamber is connected to the main water supply pipeline, while the air chamber is in communication with the atmosphere. The primary and secondary electromagnetic actuation mechanisms are installed on either side of the valve, and the electrical control box is installed in a location nearby, as specified by the design requirements. Once the electrical control module of the valve is powered on, the main and auxiliary electromagnetic operating mechanisms are pulled by the force of the electromagnets; as a result, the valve shaft moves, and the rubber seals located on the shaft come into contact with the two valve seats, thereby sealing them off. This prevents air from entering the water chamber and the air chamber, thus creating a siphon effect. When the electrical control module of the valve loses power, the electromagnet immediately disengages. Driven by the storage spring, the two valve discs on the main shaft move to the right; at this point, the valve separates rapidly from its seat. Due to the negative pressure in the main pipeline, air rushes from the air chamber into the water chamber, connecting it with the main pipeline and thereby breaking the siphon effect, thus achieving separation of the water flow.

I’m most afraid of this situation where someone speaks up but doesn’t take responsibility; you can search on Baidu about it

Are you referring to a check valve, sir? ? ?

It doesn’t seem so; you can check on Baidu. It’s not convenient for me to use my phone
