Description

Water inlet pipe for electrical equipment

[ technical field ] A method for producing a semiconductor device

The utility model relates to a water inlet pipe, in particular to a water inlet pipe for electrical equipment.

[ background of the utility model ]

The water hammer is also called water hammer, and is a phenomenon that the flow rate changes suddenly and the pressure fluctuates greatly due to sudden opening and closing of a valve or sudden opening and closing of a pump station in the process of conveying water or other liquids. It is a popular understanding that a valve closes too quickly or a power failure occurs suddenly, etc., resulting in a water blast due to the inertia of the pressurized water flow that is not easily compressed. The pressure shock wave with large fluctuation is very easy to cause the damages of burst of the pipeline due to local overpressure, loosening of a pipeline connecting port or damage of equipment and the like.

The water hammer strength decreases progressively from the valve in the direction opposite to the water flow, namely: the closer to the valve, the stronger the water hammer. Generally, it is necessary to add a water hammer treatment device in the vicinity of the valve to minimize the impact of the water hammer on the pipe or equipment.

Many wading equipment, especially washing machine or dish washer etc. domestic appliance all carry out the switch of rivers through the solenoid valve, and the stroke of solenoid valve switch is only tens of milliseconds usually, can produce powerful water hammer shock wave. Therefore, the water inlet pipe bursts or the joint loosens, and great property loss is easily caused when the situation happens.

In order to prevent the electric appliances including the above mentioned devices from being damaged by water hammer impact, the prior art generally installs a water hammer processing device at the faucet or the angle valve at the front end of the water inlet pipe to reduce the impact of water hammer generated when the electromagnetic valve of the device is opened or closed, such as the waterproof hammer buffering angle valve of chinese patent publication No. CN212564695U, and a valve box of a washing machine of publication No. CN 213017976U. Compared with the water inlet interface, the water inlet pipe and the connecting ports of the water inlet pipe belong to a rear-end processing scheme.

In fact, the rear-end processing scheme has a poor processing effect, and does not absorb the water hammer shock wave from the near end away from the valve, the water hammer still impacts the connection port of the connector and the water inlet pipe, and the connection port of the water inlet pipe and the faucet or the angle valve, and the risk of pipeline burst or connection port loosening is still large.

The more preferable scheme is to process the water hammer shock wave generated by the electromagnetic valve of the electrical equipment at the near end of the electromagnetic valve, namely a front-end processing scheme.

The present invention has been developed based on the above.
