Problems solved by technology

[0005] The present invention mainly solves the technical problem that the liquid level valve switches too fast to cause loss acceleration when the peak water consumption is not considered in the original technical scheme, and provides a parameter optimization method for the waterproof hammer intelligent secondary water supply device. Optimize the water inlet control effect of the self-operated liquid level control valve, which can not only replenish water as soon as possible to ensure the storage function of the water tank, but also reduce the sudden change of water inlet and avoid water hammer in the pipeline caused by opening or closing the valve too fast, thereby reducing the loss of the valve and extending the life of the valve. Valve service life

Embodiment

[0076] Embodiment: The parameter optimization method of a waterproof hammer intelligent secondary water supply device of this embodiment, such as figure 2 shown, including the following steps:

[0077] S1 establishes the water inlet model of the water tank, which includes:

[0078] S1.1 Set the parameters of the water tank inlet model, such as figure 1 As shown in the schematic diagram of the water inlet adjustment of the water tank, set the spring K1 deformation variable x, and the water tank liquid level height h (referring to the height from the bottom of the tank to the liquid level) when entering and leaving the water. Adjust the setting screw B to set the value of the spring K1, you can set the maximum and minimum values ​​of the liquid level, and set the height of the water tank liquid level when the valve is closed to H max .

[0079] According to the principle of the connector, the water tank C is connected with the valve cavity A, and the force acting on the lowe...

Embodiment 2

[0126] Taking a cell as an example, the specific implementation of the method of the present invention will be described.

[0127] The diameter of the water inlet pipe of the community is The average daily water consumption of the community from November to December is 518m 3 , the maximum daily water consumption is 699m 3 According to the design requirements and specifications of the water tank, it needs to meet 20%-25% of the maximum daily water consumption, so the design is based on 700m 3 Considering that the effective volume of the water tank is 140m 3 .

[0128] Step 1: Build a water tank inlet model

[0129] Combined with the data of this community, it is known that the diameter of the water inlet pipe of the community is ρ is the density of water, the gravitational acceleration g=10N / kg, the inner diameter of the water tank C is d=9.5m, the flow rate is 1.4m / s, the area of ​​the diaphragm M is S=0.04㎡, and the head loss ΔH at the valve can be obtained from the f...

Abstract

The invention discloses a parameter optimization method for a water-proof hammer intelligent secondary water supply device. target; S4 determines optimization parameters through calculation. The above technical solution can not only replenish water as soon as possible to ensure the adjustment and storage function of the water tank, but also reduce the sudden change of water inflow to avoid the sudden change of water intake, which may be caused by opening or closing the valve too quickly. Pipeline water hammer, thereby reducing the loss of the valve and prolonging the service life of the valve.

Description

technical field [0001] The invention relates to the technical field of urban water supply, in particular to a parameter optimization method for a water-proof hammer intelligent secondary water supply device. Background technique [0002] The water tank of the second water supply pump room of the community often uses a floating ball valve to control the water inflow. There are problems such as small water level control range, frequent movements, and water inflow vibration noise. It has been gradually replaced by a self-operated liquid level valve. [0003] Some data show that in residential areas, residential water consumption is concentrated in the morning and evening peaks, and different residential areas have different peak water consumption curves. If the self-operated liquid level control valve is put into operation according to the fixed parameters, it will lose sight of the one and the other in terms of the water level control range, the safe liquid level of the water ...
