Description

Technical Field

[0001] The utility model belongs to the field of water treatment equipment, in particular to a pre-water treatment device. Background Art

[0002] The pre-water treatment device is a commonly used water treatment equipment. It can pre-treat tap water or well water, remove impurities, sediment, chlorine, odor, microorganisms and other substances in the water, and improve the water quality. However, the pre-water treatment device also has some disadvantages, mainly including the trouble of replacing filter materials and the inability to offset the water hammer effect.

[0003] First, the filter element of the pre-water treatment device needs to be replaced regularly, otherwise it will affect its filtering effect, and even cause reverse osmosis, resulting in deterioration of water quality. However, replacing the filter element requires disassembling the equipment, taking out the old filter element, and then installing a new one. The whole process is cumbersome and requires professional technicians to operate, which is not convenient for users to replace by themselves.

[0004] Secondly, the pre-water treatment device is prone to water hammer effect during operation. Since the water flow rate of the pre-water treatment device is small, while the water flow rate of the water inlet pipe is large, once the water inlet pipe is suddenly closed, it will cause water hammer effect, generate shock waves, damage the pipes and equipment, and reduce the service life. Although the water hammer effect can be offset by installing devices such as pressure reducing valves, these devices require additional costs and maintenance costs, which increases the operating costs of the equipment. Therefore, it is necessary to propose a new structure to solve the above technical problems. Utility Model Content

[0011] As a preferred embodiment, one end of the water outlet pipe 2 away from the pressure relief tank is connected to a subsequent water treatment device, and the valve is a solenoid valve, which is electrically connected to a control device and a power supply through electric wires.

[0012] After adopting the above technical scheme, the beneficial effects of the utility model are as follows: by setting the tank body 1 and the tank body 2, the upper surface of the tank body 1 is equipped with a water inlet pipe 2, the water inlet pipe 2 is connected to the water inlet pipe 1 through a connecting pipe, the end of the water inlet pipe 1 away from the connecting pipe is connected to the water supply device, the tank body 1 and the tank body 2 are both provided with a receiving cavity inside and are connected to each other, and the lower surface of the tank body 2 is equipped with a pressure relief tank through the water outlet pipe 1.

After the water source is processed through the tank body 1 and the tank body 2, it enters the pressure relief tank from the water outlet pipe 1, and then the water source enters the water outlet pipe 2 from the pressure relief tank. Subsequently, the valve on the surface of the water outlet pipe 2 is opened through the control device so that the water source can be used subsequently. A check valve is arranged inside the water outlet pipe 1 to prevent the water source from flowing back into the tank body 1 and the tank body 2. When the valve is closed, the water flow will produce a water hammer effect. If this phenomenon is not offset, the connection of the device will be separated in the long run. Therefore, when the valve is closed, the water flow will enter the pressure relief tank, thereby offsetting most of the water hammer effect to extend the service life of the device.
