At this time, the pressure unit (4) is the same as the hydraulic pressure of the use pipeline (4), and both are in a high shape, that is, the inside of the pressurizing unit is in a high pressure state for a long time, and the pressure is caused by the test unit. The problem of liquid leakage. [New content] The purpose of this new type is to provide a pressure pump that can prevent internal liquid pressure from being in a high pressure for a long time to prevent leakage. Therefore, the new pressure pump is suitable for pumping water in a water source pipeline: in the pipeline, the pressure pump comprises: a pressurizing unit connected to the water source pipeline, and a connection to the pressurizing unit and Use the reverse unit between the pipelines and a pressure switch assembled on the non-return unit. The pressurizing unit has a driving machine, and a driven machine is driven to push the water in the water supply line of the 5 M321948 to the press machine in the use line. The anti-reverse unit has a cover that is assembled between the press and the use pipeline, a cover that is hermetically sealed to the top of the check socket, and a central shaft that can be placed on the check socket a check valve that moves up and down, the check tube seat has a small aperture section connected to the press machine, an axial connection to the aperture section, and a material to the large hole (4) and the water outlet section of the connection . The cover has a cover body that covers the top end of the large aperture section of the check socket, a duct portion that protrudes downward from the bottom surface of the cover body, and an induction coil that is embedded in the cover body and extends horizontally horizontally . The check valve has a valve plate covering the top end of the small aperture section of the check tube seat, a guide post extending upward from the top surface of the valve plate and extending into the conduit portion of the cover, and a fixed guide The magnet at the top of the column. The pressure switch is assembled on the check tube seat and starts the operation of the pressurizing unit when the use line pressure is lower than a predetermined value, pushing the water liquid upward and driving the check valve up, and the water liquid is made of a small hole diameter The section flows to the large aperture section and the used pipeline. When the use of the pipeline is the same as the pressure in the small aperture section, the check valve is closed to the top of the small aperture section by the sinking reset, the magnet is away from the induction coil, and the induction coil output signal turns off the pressurization unit. The utility model has the advantages of using the anti-reverse unit assembled between the pressurizing unit and the use pipeline to prevent the water in the use pipeline from flowing back to the water source pipeline=feeding element, and the pressurizing unit can be avoided The hydraulic pressure is in an A-press state for a long time, and the chance of leakage is reduced, and the induction coil assembly is embedded in the cover body to reduce the need for 6 M321948 water sealing when the conventional induction coil wiring is installed, thereby reducing the assembly cost. . The above and other technical contents, features and effects of the present invention will be apparent from the following detailed description of the preferred embodiments. Referring to Figures 1, 2 and 3, a preferred embodiment of the present pressurized pump is adapted to pressurize the water in a water source line 21 into a use line 22, which includes A pressurizing unit 3 connected to the water source line 21, a check unit 4 connected between the pressurizing unit 3 and the use line 22, and a pressure switch 5 assembled to the check unit 4. In the present embodiment, the pressurized water solution is taken as an example, but in practice, it can also be used for pressurizing fuel or hydraulic oil, etc., and the implementation range is not limited to the type of the pressurized liquid described above. The pressurizing unit 3 has a driving machine 31, a press machine 32 driven by the driving machine 31, a water inlet official 33' connecting the other end of the pressurizing machine 32 to the water source line 21, and a communication presser 32. And outputting the effluent of the pressurized water solution I 3 4 in the embodiment of the present invention, the driving machine 31 is an electric motor, and the driving machine 31 T moves the press machine 32 to add water in the water source line 21 The pressure is pumped into the use line 22. The anti-reverse unit 4 has a rear end seat 41 which communicates with the outlet pipe 34 and extends upward, a cover 42' which is airtightly attached to the top end of the check tube seat 41, and a stop tube seat The check valve 43 is moved up and down in the axial direction of the 41. The anti-reverse seat 41 has a small aperture section 411 connected to the outlet pipe 34, and a large aperture section 412 axially connected to the top end of the small aperture section 411. The shoulders 413 between the large and J-holes 412 and 411, and a water outlet section 414 connected to the side of the large-aperture section 412 M321948 and connected to the pipeline 22. The cover 42 has a cover body 421 which is made of a plastic material and is attached to the top of the large aperture section 412 of the check socket 41. The cover body 421 extends downwardly from the bottom edge of the cover body 421 and is screwed to the check tube. The screw portion 422 of the inner peripheral surface of the distal end of the large aperture portion 412 of the seat 41, a duct portion 423 projecting downward from a central portion of the bottom surface of the cover body 421, and a sensing coil 425 fixed to the top surface of the cover body 421. The 5 mile induction coil 425 is wound around a horizontal axis and embedded in the cover body 421. In the embodiment, the induction coil 425 is fixed on the top surface of the cover body 421 and then filled around the induction coil 425 with an insulating plastic material such as silicone rubber, but the implementation range is not limited to the above-mentioned fixing manner. In order to achieve the anti-reverse effect, the check valve 43 has a valve plate 431 covering the top surface of the shoulder 413 of the check socket 41, and the three intervals are extended downward from the bottom edge of the valve plate 431 into the small aperture section 411. The guide pin 432 is a guide post 433 extending upward from the top surface of the valve plate 431 and extending into the conduit portion of the cover 42 and a magnet 434 fixed to the top end of the guide post 433. When the guide pins 432 are inserted into the small aperture section 411 t of the anti-reverse tube seat 41, they are respectively abutted against the inner circumference of the child hole valley & 411, that is, by the guide legs In the aperture section 411, the guide post 433 is simultaneously inserted into the guide 142 of the cover 42 to limit the valve plate 431 to remain horizontally along the central axis of the small hole diameter section 411. The axial direction of the aperture section 412 is not deflected up and down, and the effect of preventing the water from flowing back to the water source line 2 is achieved. The force switch 5 is assembled on the check tube seat 41, and when the pressure of the use line 22 is lower than a predetermined value, the drive unit of the pressurizing unit 3 is started to operate, and the rotary press machine 32 is used to turn the water source line. The water in 21 is pressurized and pushed to the water outlet 8 M321948 tube 34. The pressure switch 5 is a common accessory in general pressurized pumping equipment, which is not a feature of the present invention. The following is no longer a description of its working principle. When the water in the use line 22 is consumed for use, causing a pressure drop in the use line 22, the pressure switch 5 immediately starts the operation of the pressurizing unit 3, the water in the water source line 21 Pressurized into the small aperture section 411 of the anti-reverse seat 41, when the water flows upward, the check valve 43 is pushed upward as shown in FIG. 4, and the magnet at the top of the guide post 433 is particularly close The magnetic line generated by the magnet 434 of the induction coil 425 passes through the induction coil 425 and induces a confirmation signal on the induction coil 425, while the water flows from the small aperture section 411 to the large aperture section 412, and then flows to the large aperture section 414. Use in line 22. See Figures 2, 3 and 4, when When the line 22 is closed and sad, and no output water is used, the hydraulic pressure in the use line 22 rises due to the operation of the pressurizing unit 3, when the hydraulic pressure in the use line 22 rises and is in the small aperture section 411. When the hydraulic pressure is the same, the water will not continue to enter the large aperture section 412. The check valve 43 will sink due to its own gravity, so that the magnet 434 is separated from the induction coil 425, and the induction coil 425 is The confirmation signal disappears. The pressurizing unit 3 can stop operating according to the disappearance of the confirmation signal until the hydraulic pressure in the pipeline 22 is too low to start the pressurizing unit 3 again by the pressure switch 5. This pressurization in this embodiment The process in which the unit 3 stops operating due to the disappearance of the confirmation signal on the induction coil 4 is a common technique in general automatic control, and will not be further described below. It will be apparent from the above description that when the use line 22 is used When the liquid 9 M321948 is twisted and the hydraulic pressure is the same as that in the add-on A 3 , the check valve 43 of the check unit 4 is immediately moved downward to cover the shoulder 413 of the check socket 41 to prevent water and liquid. Returning back to the pressurizing unit 3 to avoid the pressurization list The fluid pressure in the third is maintained at a high pressure for a long period of time, and the pressure rise is temporarily maintained only in the state in which the pressurized process towel is maintained, thereby reducing the chance of bubble leakage in the pressurizing unit 3. Further, the induction coil 425 of the check unit 4 is horizontal. The cover member 421 is fixedly attached to the top surface of the cover body 421 of the cover 42 to avoid fixing the induction coil 425 in the conduit portion 423 of the cover 42 and considering the problem of water sealing when the electric wire is connected. The assembly cost also reduces a problem that may cause leakage. It is worth mentioning that by the check signal of the check valve 43 moving up close to the induction coil 425, it can be determined that there is no water source in the water source line 21, and the pressurizing unit is avoided. 3 is in an idling state. That is, when the hydraulic pressure in the pipeline 22 is too low and there is no water source in the water source pipeline 21, after the pressurizing unit 3 is started, the check valve 43 is not pushed up by the water liquid, and the induction coil 425 does not sense. By confirming the signal, it is judged whether there is a water source in the water source pipe 2丨 by confirming the presence or absence of the signal, and whether the pressurizing unit 3 is idling, and immediately controlling the pressurizing unit 3 to stop, so as to prevent the pressurizing unit 3 from being burnt due to idling . Further, when the pipe 22 is pressurized and the pressure in the small diameter section 411 of the check pipe 41 is the same, the check valve 43 is moved downward by gravity, and the speed of the downward movement is due to buoyancy in the water. Slowly delaying the time when the signal is disappeared on the induction coil 425, thereby delaying the time when the pressurizing unit 3 is stopped, so as to avoid the driving machine 31 of the pressurizing unit 3 being caused by a small amount of water in the use line 22 for a short time. Start and stop the problem. 10 M321948 In summary, the present invention utilizes the check unit 4 assembled to the pressurizing unit 3 and the use of the check unit 4 of the line 22 to avoid backflow of the water in the line u back to the water source line 21, Moreover, the pressure in the pressurizing unit 3 can be prevented from being in a high pressure state for a long time, and the chance of leakage is reduced, and the night induction coil 425 is assembled and embedded in the cover body 421 to reduce the wiring of the induction coil 425. When it is necessary to seal the water and reduce the shame, it is indeed possible to achieve the purpose of the present invention. The above-mentioned ones are only the preferred embodiments of the present invention, and can limit the scope of the implementation of the present invention, that is, the simpleness of the scope and the new description contents of the present invention. Effect changes and modifications: Within the scope of this new patent. BRIEF DESCRIPTION OF THE DRAWINGS FIG. 2 is a front elevational view showing the preferred embodiment of the present invention.
