The present invention relates to a press machine, and more particularly to an indirect water press press that is mounted on a fluid delivery conduit system and assists fluid delivery in a pressurized manner.

In order to store enough water, a general building will install at least one water tower on the top floor of the building. In order to transfer the water source to the water tower located in the high place, a press machine is usually installed between a water pipe and the water tower. . However, according to the regulations of the water company in China, the press machine cannot be directly connected to the water pipe because the tap water pipe system is a closed design and is buried under the surface for a long time. Therefore, after using for a period of time, It is inevitable that the pipeline system will produce tiny cracks or voids. Because rainwater and sewage will flow under the surface of the earth, there may be sediment and dirty fluid around the outside of the pipeline system.

In the case of normal water supply, the press machine can send the water source to the water tower in the high place, but when the water supply end stops the water supply due to external factors, the press machine that continues to operate will not only idle, but also let the tube The negative pressure is gradually generated inside the road system. In the case of unbalanced pressure inside and outside the pipeline system, the polluted fluid and fine sediment outside the pipeline system may enter the pipeline system through tiny cracks and pores. Internally, the water source is polluted. In order to maintain the safety of public drinking water, the competent authority prohibits the direct installation of the press on the water pipe. The main reason for the aforementioned deficiency is that the conventional press lacks a mechanism for preventing the generation of negative pressure, and the present invention is directed to the improvement of the aforementioned defect.

In the normal use state, the water supply device enters the liquid storage space 310 of the extension water tank 3 from the liquid inlet pipe 11 in the normal use state, and most of the liquid will enter the cavity from the second pipe portion 315. In the pressurizing chamber 210 (see FIG. 2) of the body 21, most of the liquid is sent out from the liquid discharge line 12 by the pressurization of the pressurizing pump 22. A small portion of the liquid enters the buoyancy space 320 from the liquid storage space 310. Under the action of the buoyancy, the floating body 42 moves upward, and the connection of the linkage member 41 drives the ventilation control rod 43 to move up. When the anti-leakage protrusion 432 of the venting lever 43 presses the leakage preventing ring 44 against the tub cover 33, the negative pressure releasing mechanism 4 will be located at a closed position shown in FIG. 3, that is, the entire piping system is In the closed state, liquid can be continuously supplied from the liquid inlet line 11 to the liquid discharge line 12.

Referring to Figures 1, 2, and 5, when the supply of the water source is unable to flow into the liquid storage space 310 by the liquid inlet line 11, the pressure pump 22 continues to generate power to draw the liquid to the liquid discharge line 12. At this time, the liquid level in the liquid storage space 310 and the buoyancy space 320 connected thereto may suddenly drop. At this time, the floating body 42 originally supported by the liquid buoyancy is lowered, and the interlocking member 41 is interlocked. The ventilation lever 43 is lowered, and when the anti-leakage protrusion 432 of the ventilation lever 43 is separated from the leakage prevention ring 44, external air can enter the buoyancy space 320 from the air passage 330, and finally through the storage. The liquid space 310 enters the pressurizing chamber 210. That is, in the case where the water supply is insufficient, although the pressurizing pump 22 continues to generate the suction force, since the air passage 330 has been opened, the outside air can be sucked into the liquid storage space 310 by the air passage 330, whereby Achieve the purpose of preventing the formation of a negative pressure in the piping system.

As can be seen from the above description, the present invention adds the extension water tank 3 between the pressurizing mechanism 2 and the liquid outlet pipe 12, and the structure of the negative pressure release mechanism 4 is provided on the extension water tank 3, which is not only an unprecedented innovation. In addition to the negative pressure in the pipeline system, the foregoing structure can ensure the pipeline system during the process that the outside air is about to enter the liquid storage space 310, since there is still some liquid inside the liquid storage space 310.
