New description: [New technical field] This creation is about the valve body structure, especially a valve body structure that uses water pressure to control the valve body to be in circulation or closed state. [Prior Art] In order to provide safe and hygienic drinking water, various water filtering devices with different functions can be selected on the market, for example, a water filter for filtering impurities in water by a multi-layer filter, a R0 reverse osmosis water filter, And UV UV lamp sterilization type water filter and so on. No matter which type of water filter device is installed, it will encounter the same water pressure problem during installation and use, which may cause inconvenience or damage to the water filter device. The water pressure problem mainly comes from two parts: 1. When the fluid in the pipeline flows, if the valve body is suddenly closed to stop the fluid, the kinetic energy of the fluid will be converted into elastic energy, which will generate a series of positive and negative pressure waves in the pipeline. Vibrating back and forth, this is the action of water shovel; especially when the pump stops running, the fluid continues to flow due to inertia and flows back due to the gravity of the fluid, thereby generating the vibration of the pipeline caused by the encounter of the positive and negative pressure waves in the pipeline, and this The action of the water raft is often used in the open and closed state, and the elastic oscillating fluid pressure also damages the water filter, resulting in a decrease in the service life of the water filter; 2. The user terminal may be located in different areas of the water supply system. If the water pressure is not the same, if the water pressure is too large, the direct impact into the water filter will also cause unnecessary damage. Therefore, there is still room for improvement in the actual use of the water filter. . [New content] In view of the above-mentioned use problems, the author believes that it is necessary to design a protective valve structure that can be opened or closed according to fluid pressure between the water inlet pipe and the water filter to reduce the fluid flow path. When it is cut off, the influence of fluid consistency and gravity on the water filter and the inlet pipe parts can effectively protect the water filter and prolong its service life.

The deformation force of the M418724 through the rubber structure of the piston structure is matched with the elastic force provided by the elastic member and the elastic member. When the fluid flow path is closed to generate the stagnant hydraulic pressure, the piston structure is downwardly displaced by force, and the water retaining member is also At the same time, the body port is closed downward to block the flow of the fluid to the water purifier or the connecting pipe, so as to avoid damage of the water purifier or the related connecting pipe caused by the continuous pressure rise.
