The cross screw can be rotated by the screwdriver, so that the adjusting screw rod is driven to rotate. When the cross screw rotates forwards, the adjusting screw rotates forwards along with the cross screw, so that the upper baffle plate rises, the extrusion force of the spring to the lower baffle plate is increased, the valve rod moves downwards more easily, the valve core is pushed open by the water pressure of the water inlet more easily, the flow is increased, and the water pressure of the water inlet is reduced. Conversely, the cross screw is reversely rotated, so that the water pressure of the water inlet is increased.

Furthermore, a round hole for inserting a screwdriver is formed in the upper end of the valve body, and the cross screw is located in the round hole.

Furthermore, the core print comprises an upper print portion and a lower print portion, and the upper print portion and the lower print portion are connected through a plurality of upright posts.

Further, the upper end of the valve rod is fixedly connected with the lower baffle through threads.

Further, the filter flask is connected with the upper cover cap through threads.

Compared with the prior art, the preposed water filter with the pressure regulating function has the advantages that:

1. the automatic balance function, the extrusion force of cooperation spring to and the water pressure of rivers backs down the case, and the water pressure of intaking is big more, and the aperture of crossing the water hole is big more, realizes the hydraulic effect of automatic balance delivery port.

2. The manual fine adjustment function can adjust the height of the upper baffle plate by rotating the cross screw, change the extrusion force of the spring to the lower baffle plate and finely adjust the threshold value of the water pressure jacking valve core.
