The present invention discloses a high-precision gate shearing machine and a method for fine-tuning the blade gap, which belongs to the forging machine tool technology. It includes a tool holder body, wherein a group of limiting structures are arranged on both sides of the top of the tool holder body, a rear fulcrum is arranged on the rear side of the tool holder body, and a front fulcrum is arranged on the front side. The two groups of limiting structures are slidably matched with sliding components inside, and the two groups of sliding components are respectively installed on the corresponding oil cylinders. The new upper tool holder stable structure basically adopts a three-point support structure, but the rolling rear upper fulcrum is changed to a sliding sliding component.

This invention relates to a bathroom hot water heating system, comprising: a heating device, an outlet valve, and a heating unit. The heating device heats water flowing from the inlet channel to the outlet channel and operates in either a water supply or heating mode. The outlet valve is connected to both the inlet and outlet channels and can switch between a closed and an open state. In the open state, the outlet valve allows water to flow from at least one of the inlet and outlet channels. In the closed state, the outlet valve stops the flow from both the inlet and outlet channels. The inlet end of the heating unit is connected to the outlet channel, and the outlet end is connected to the inlet channel. Because the heating unit is directly connected to both the inlet and outlet channels, complex connecting pipes between the heating unit and the hot water equipment are avoided, thus simplifying the connection between the hot water equipment and the heating unit and reducing the installation difficulty and cost of the heating terminal.
