Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Example 1:

Referring to fig. 1-4, a check valve structure applied to a booster water pump comprises a plastic shell 1, wherein a valve core assembly 2 is arranged in the plastic shell 1 in a moving manner, the valve core assembly 2 comprises a valve body 3, a spring 4, a magnetic ring 6 and a valve core rod, the valve body 3 is arranged on the valve core rod, the magnetic ring 6 is arranged in the valve core rod, the spring 4 is connected between the valve body 3 and the valve core rod, one side of the plastic shell 1 is connected with a sensor 5, the sensor 6 is integrated with a pressure sensor, one end of the sensor 5 is provided with a coil 7 in a moving manner, a metal thread ring 8 is arranged in the plastic shell 1, and the metal thread ring 8 is used for preventing cracking risks brought by plastic thread connection.

In this implementation, set up the internal thread on the inner wall of plastics casing 1, metal thread ring 8 threaded connection is in the inboard of plastics casing 1, and case subassembly 2 motion is connected in metal thread ring 8, and the both ends of valve core pole all move and run through to the outside of plastics casing 1, and sensor 6 external connection has the controller, and its action control ware is according to rivers and the operation of water pressure synchronous control water pump, can more accurate provide accurate water pressure.

Working principle: when a user works with water or the booster water pump, the water flow can flush the valve core component 2 due to pressure difference generated in the water pipe, at the moment, the check valve is positively conducted, and the sensor 5 senses that the valve is opened due to the rising of the magnetic ring 6, so that the water pump starts to operate. When the user does not need to use water, no water flow exists on the pipeline, under the action of the spring 4, the check valve is closed and returns to the initial position, the sensor 6 senses that the valve is closed due to the descending of the magnetic ring 6 and transmits a signal to the control board, the control board controls the water pump to stop, thereby preventing the water from flowing back, the water outlet keeps certain pressure, and when the user needs water again, the water flow rushes out of the valve core assembly 2 again, and the check valve is opened.

This example 2:

Referring to fig. 5, on the basis of embodiment 1, the following technical scheme is also provided:

the outer surface of the plastic shell 1 is provided with a through hole, the sensor 5 is arranged in the through hole, the coil 7 is connected in the plastic shell 1, one end of the sensor 5 is connected to the coil 7, the bottom end of the valve body 3 is connected to the top surface of the valve core rod, the magnetic ring 6 is arranged at the bottom end of the valve core rod, and the magnetic ring 6 is in electromagnetic connection with the electrified coil 7.

Working principle: the device can also integrate the coil 7 internally, the controller supplies direct current in different directions to the coil 7 to generate magnetic force, and the magnetic force interacts with the magnetic ring 6, so that when the spring 4 fails or the water valve needs to be opened and closed, the water valve is effectively controlled, and the locking force and the releasing force are increased when the water valve is closed, thereby improving the sealing performance.
