Description

Safety water purifier pressure barrel pressure relief valve device

Technical Field

The utility model belongs to the technical field of the water purifier pressure barrel, concretely relates to security water purifier pressure barrel relief valve door gear.

Background

The pressure barrel of the water purifier is also a water storage barrel, the pressure barrel works under pressure as the name suggests, water is drained or fed through the pressure of an air bag in the pressure barrel, when the barrel is empty or not full, purified pure water of the water purifier flows into the pressure barrel, and when the water pressure in the barrel and the pressure of the air bag reach balance, the water purifier stops working; when the water faucet is opened, the air bag can generate rebound force due to the extrusion of pure water, so that the pure water in the barrel is discharged, and the discharged pure water flows to the active carbon filter element of the last stage because of the check valve and is discharged through the water faucet. After the pressure barrel is emptied of pure water, the water purifier works again, and then the cycle work is repeated. For reasons of pressure drums to be filled: the RO membrane is mainly used for purifying water in a reverse osmosis mode, so that the water passing amount is small, the requirement of instant drinking cannot be met, and the requirement of waiting for three or five minutes or even longer for drinking a cup of water is always met. The effect of pressure bucket is exactly when you do not need the water, the water storage, in the time of the water, pressure bucket discharge water supplies you to use, in order to guarantee the security of the inside gasbag of pressure bucket, generally at the bottom installation pressure release valve of pressure bucket, when overhauing the pressure bucket, can carry out the pressure release to the gasbag through pressure release valve, the dismantlement of the pressure bucket of being convenient for is overhauld.

However, some unreasonable factors still exist in the use process of the pressure relief valve for the safety of the existing water purifier pressure barrel, and when the pressure relief valve for the safety of the existing water purifier pressure barrel is used: the sealed head of relief valve uses for a long time etc. reason easily ages, and sealed head after ageing then can lead to the leakproofness of relief valve to reduce, needs in time to change, and present pressure bucket safety relief valve is not convenient for install change internals, and the pressure release is also more troublesome, and the practicality is relatively poor.
