Description

Pressure flushing system suitable for low water pressure

Technical Field

The utility model relates to a be fit for low hydraulic pressure flushing system.

Background

The flushing system of the existing intelligent closestool mainly has two categories: the first type is flushing by using the pressure of tap water; the second type is that the water storage drain valve of the water tank is opened and then the water is flushed by gravity. For the latter, because the water tank of the intelligent closestool is all lower, the gravitational potential energy of the flushing of the drain valve is very low, the flushing force of the closestool is all worse, and the scheme is not well improved.

For the first type of pressure flushing, two types can be used: one is that the pressure of the tap water pipeline is controlled by an electromagnetic valve to directly flush water; the other is that the air energy storage tank accumulates the water pressure of the tap water and then the flushing valve is opened for flushing through a specially designed flushing valve. For the first system for controlling flushing by an electromagnetic valve, the requirement on the diameter of a pipeline is high, at least 6 minutes of hoses are generally used for connecting an angle valve water source, the water pressure cannot be too low, and the flow rate cannot be too small, the current specifications of similar products on the market all specify that the flow rate cannot be lower than 21 liters per minute, the actual toilet needs to reach the flow rate, the water pressure at least needs to reach 25PSI, and the system is difficult to use in low-pressure areas such as 20PSI or lower 15PSI areas.

For the second kind relies on the pressure flushing system of air energy storage, the minimum normal operating water pressure that industry no water tank closestool can accomplish at present is 25PSI, and when the water pressure is low to 20PSI even lower 15PSI, the impulsive force of the no water tank closestool of air energy storage will greatly reduced, and domestic has the high-rise water pressure of many old districts and really has the condition down to 20PSI, and many countries in southeast Asia also have this kind of low pressure 20 PSI's user demand. How to improve the toilet bowl impulsive force under the low pressure condition to make the water tank-free toilet bowl capable of being expanded to a larger use scene is a difficulty of the current whole industry.
