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: A parameter optimization method of a water hammer intelligent secondary water supply device in this embodiment, such as figure 2 shown, including the following steps:

[0077] S1 establishes a water tank intake model, specifically including:

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

[0079] According to the principle of the connector, the water tank C communicates with the valve cavity A, and the force acting on the bottom of the diaph...

Embodiment 2

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

[0127] The diameter of the residential water inlet pipe is The average daily water consumption of the community from November to December is 518m 3 , the highest daily water consumption is 699m 3 According to the design requirements of the water tank, it is necessary 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: Create a water tank model

[0129] Combined with the data of the community, it is known that the diameter of the water inlet pipe in the community is ρ is the density of water, the acceleration of gravity g=10N / kg, the inner diameter of water tank C is d=9.5m, the flow velocity is 1.4m / s, the area of ​​diaphragm M is S=0.04㎡, and the head loss ΔH at the valve can be expressed by formula (10) inferred.

Abstract

The invention discloses a parameter optimization method for a water hammer-proof intelligent two-way water supply device. The parameter optimization method comprises the following steps: S1, establishing a water tank water inlet model; S2, collecting data and checking the water tank water inlet model; s3, determining an optimization variable, a constraint condition and an optimization target; and S4, determining optimization parameters through calculation. According to the technical scheme, the water tank water inlet model is established, the water inlet control effect of a self-operated liquid level control valve is optimized, water can be supplemented as soon as possible, the water tank regulation and storage function can be guaranteed, water inlet sudden change can be reduced, pipeline water hammer caused by too fast valve opening or closing can be avoided, accordingly, valve loss is reduced, and the service life of the valve is prolonged.

Description

technical field [0001] The invention relates to the technical field of urban water supply, in particular to a method for optimizing parameters of an anti-hammer intelligent secondary water supply device. Background technique [0002] The water tank of the second supply pump room in the community often uses a float valve to control the water intake. There are problems such as small water level control range, frequent movement, and water intake vibration noise. It has been gradually replaced by a self-operated liquid level valve. [0003] According to data, in residential areas, residents' water consumption is concentrated in the morning and evening peaks, and different communities have different peak water consumption curves. If the self-operated liquid level control valve is put into operation according to fixed parameters, it will lose sight of the water level control range, the safe liquid level of the water tank, and the valve opening range. For example, if the valve is ...
