Description of the invention () Background of the invention: The present invention is a flow balance adjustment device for hydraulic presses. Hydraulic press flow balance adjustment device. According to the current water supply systems of ordinary buildings and other public places, in order to maintain the water pressure of the water supply pipelines stable, and to maintain proper water calendar everywhere in the building, it is usually installed on the water supply pipelines. A hydraulic press that stabilizes water pressure. The control system used to control the pressure-stabilizing water press can be divided into mechanical pressure difference type hydraulic presses and frequency conversion constant pressure type hydraulic presses controlled by frequency conversion motors. Among them, the frequency conversion type hydraulic press uses a frequency conversion motor that can change the speed to drive the pressure pump, and a frequency converter to control the speed of the motor. The frequency converter can be controlled by a water pressure sensor to change the speed of the frequency converter motor. The lotus mode is to use a water pressure sensing device to sense the pressure of the water supply pipeline. When the pressure of the pipeline is low, the motor can be controlled to rotate at a higher speed, and when the water pressure is close to the water in the water supply pipeline. When the upper pressure limit is reached, the rotation speed of the motor is reduced, and when the water pressure exceeds the upper limit pressure, the motor is controlled to stop lotus rotation. Therefore, when the amount of water in the water supply pipeline is large, the pressure drop in the pipeline is large. At this time, the inverter can control the motor to run at a higher speed to increase the water output of Quanpu and increase the pressure of the water supply pipeline. ; When the water consumption of the water supply pipeline is small, the pressure drop of the water supply pipeline is small. At this time, the inverter can control the motor to operate at a lower speed, so that the water output of Lipu is reduced and the water supply pipeline is reduced. The pressure does not rise quickly. The advantage of the inverter-type short-pressure hydraulic press is that it can be controlled by the inverter.-2-This paper size applies the Chinese National Standard (CNS) A4 specification (210X297 mm) II n Batch I I order I. n H line (please first Read the notes on the back and fill in this page) 498133 A7 B7 _____ V. Description of the invention () Please read the item i on the back and fill in the speed of the motor so that the water output of the pump can match the water consumption of the water supply pipeline, so Μ precisely controls the speed of the motor to avoid the rapid rise in the pressure of the water supply line after the motor is started, which causes the motor to stop immediately after the rapid start. Therefore, the hydraulic motor can run smoothly and the lotus rotation efficiency of the motor is improved. save energy. However, the variable frequency constant pressure hydraulic press must use a variable frequency motor with a complicated structure, and the cost of the variable frequency controller is very expensive. Therefore, the price of this variable frequency hydraulic press is very high, and its maintenance cost is also quite high. In addition, the inverter generates high heat during use. Therefore, the control box of the hydraulic press must be equipped with an appropriate heat dissipation system, and the inverter is often burnt due to overheating during use. Due to the above reasons, the conventional variable frequency constant pressure hydraulic press is expensive and difficult to maintain. Therefore, the variable frequency hydraulic press can usually only be used in large water supply systems. The Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs printed another mechanical pressure difference type hydraulic press that uses a pressure switch to control the start and stop of the motor. The motor uses a fixed speed motor, and the pressure on relationship can set a pressure upper limit. With a lower pressure limit, when the water pressure in the water supply line is lower than the lower pressure limit, the motor is started to drive the pump to pressurize; when the pressure in the water line is higher than the upper pressure limit, the motor is controlled to stop running until the pressure in the water supply line is After the water consumption of the pipeline reduces the water calendar to the lower pressure limit M, the motor is restarted to pressurize. In addition, in order to delay the pressure rise and fall speed of the water supply pipeline, the water supply pipeline usually includes a pressure storage cylinder at the outlet of the hydraulic press. The pressure storage cylinder can contain air or an elastic membrane, which can store leeches. When the hydraulic press starts to pressurize, the water flows into the pressure storage cylinder, and when the hydraulic press stops rotating, you can use the pressure storage cylinder 1 — This paper size applies the Chinese National Standard (CNS) A4 specification (210X29? Mm) ) A7 498133 B7 V. Description of the invention () The air pressure or diaphragm pressure injects water into the water supply pipeline at a rate at which the pressure of the yuan and the water supply pipeline decreases. This kind of mechanical pressure differential hydraulic press uses a simpler motor structure and control system, so the overall structure is relatively simple, and the cost is relatively low, and the operation and maintenance are also easy. However, the motor used is a fixed-speed continuous rotation. Therefore, after the pressure switch controls the motor of the hydraulic press to start, the pump of the hydraulic press can only supply water with the maximum water output. Therefore, regardless of the amount of water in the water supply pipeline, the pump water output of the hydraulic press maintains a fixed flow. In order for the hydraulic press to be able to meet the flow rate of the water supply pipeline at the peak time of the water, the pump's effluent energy used must be able to meet the peak water flow condition in order to provide sufficient water flow. However, when the water supply pipeline is in the off-peak period, although the water consumption of the water supply pipeline is reduced, the water machine motor can still only run at full speed, so the water output of the pump is much higher than that of the water supply pipeline. Demand, when the hydraulic press is started, the pressure of the water supply pipeline will rise above the upper limit of the pressure set by the pressure switch in a short time. After the hydraulic motor is started, it will immediately stop in a short time, so the motor starts and stops. Becomes quite frequent. When the motor is running, the moment that consumes the most power is the moment of starting, so frequent starting and stopping of the motor will cause considerable power consumption. And in the low water supply state of the water supply pipeline, the motor of the hydraulic press still rotates at full speed, so that the hydraulic motor still maintains the high power consumption and high power consumption state, thus causing considerable energy consumption. What's more serious is that under low water conditions, the water flow rate of the hydraulic pump is much higher than that of the water supply pipeline. 4- This paper size applies to the Chinese National Standard (CNS) A4 specification (21〇 × 297 mm) — gutter.

Description of the invention () The output pipeline of the hydraulic press will cause serious pressure back pressure, making the hydraulic press The operation load of the pump is more serious, and the power consumption of the hydraulic motor is also very serious. Due to the reasons for M, there are quite a few shortcomings in the use of the conventional hydraulic press spike device, and there is a need for improvement. In view of this, the inventor has carefully studied and actively researched and engaged in related product development for many years. Experience, and through continuous testing and improvement, the invention has finally been developed. Summary of the invention: The main object of the present invention is to provide a hydraulic pressure machine flow balance adjusting device which can avoid the rapid start and stop of the hydraulic machine and reduce the energy consumption. Another object of the present invention is to provide a hydraulic pressure machine flow balance adjustment device that can make the water output of the hydraulic press match the water state of the water supply pipeline, and avoid the water output of the hydraulic press being greater than the water consumption, resulting in energy consumption. Yet another object of the present invention is to provide a hydraulic pressure machine flow balance adjustment device which can be used with a mechanical differential water pressure machine, so that the mechanical differential water pressure machine can exert the effect close to that of an inverter hydraulic machine.

The top of the control valve 10 is provided with a hydraulic inlet 17 which is connected to the outlet pipe 22 of the hydraulic press via a connecting pipe 23 (as shown in FIG. 1), and guides the hydraulic pressure at the outlet of the hydraulic press into Among the sister bodies 15 inside the control valve 10, the piston member 31 can be pushed downward by the water pressure. In addition, as shown in FIG. 2 and FIG. 5, the block 13 is respectively provided with receiving grooves 18 on both sides of the cylinder block 15, and the elastic element 40 and the bolt 33 are received by M. The diameter and length of the two receiving grooves 18 are larger than the width and length of the two elastic elements 40 and the bolts 33, and the bottom end of the two receiving grooves 18 is provided with an engaging portion 19, which can be used for the aforementioned washer 35 to be engaged with. The bottom end of the elastic element 40 is engaged by the engaging portion 19 and is pressed. Therefore, when the control valve Η 30 moves downward, the two elastic elements 40 can be compressed. 8- This paper size is applicable to China National Standard (CNS) 8-4 specifications (210 × 297 mm) ---------- Approved IT, a (Please read the precautions on the back before filling this page) 498133 A7 B7 5. Description of the invention () As shown in FIG. 3, the control valve plate 30 can be pushed downward by the water pressure of the outlet pipe 22 of the hydraulic press, and the elastic element 40 can be compressed at this time. Since the acting force of the elastic element 40 pushes the control valve sheet 30 upwards, when the water pressure of the outlet pipe 22 of the hydraulic machine pushes the control valve sheet 30 downward, the elastic force of the elastic element 40 must be overcome And, when the water pressure is greater, the displacement that can push the control valve sheet 30 will also increase. On the contrary, when the water pressure decreases, the elastic force of the elastic element 40 can push the control valve sheet 30 upward. By the interaction of the water pressure of the outlet pipe 22 and the elastic force of the elastic element 40, the control valve plate 30 can be displaced to different positions under different water pressure conditions, and when the height of the control valve plate 30 is When the position is changed, the degree of shielding of the water flow channel 11 by the valve tongue 32 of the control valve plate 30 also changes accordingly, so that the flow rate of the water flow passing through the water flow channel 11 is changed. According to the present invention, when the pressure of the water supply pipeline rises, the control valve plate 30 can be pushed down by the water pressure, thereby reducing the flow of water that can pass through the water flow passage 11 of the control valve 10, and when the pressure of the outlet pipeline 22 drops Then, the control valve plate 30 can be pushed up and moved by the elastic element 40, so that the degree of opening of the water flow channel 11 is increased, so that the water flow volume is increased. When the outlet pipe 22 is in a low water state, when the water output of the hydraulic press 20 is greater than that of the water supply pipe, the pressure of the outlet pipe 22 will increase, and at this time, the control valve plate 30 will also follow the water pressure. Increasing, and gradually moving downward, the water flow of the inlet pipe 21 of the hydraulic press 20 is reduced, so that the amount of water passing through the pump blades of the hydraulic press 20 is reduced, and the water output of the hydraulic press 20 is also reduced; conversely, when the water supply pipe The large amount of water used in the road makes the export of a 9-size paper suitable for Chinese National Standards (CNS) A4 specifications (210X297 male thin) (Please read the precautions on the back before filling this page) Order ## Ministry of Economic Affairs Intellectual Property Bureau Printed by the employee consumer cooperative 498133 A7 B7 V. Description of the invention () When the pressure of the pipeline 22 decreases, the control valve plate 30 can be displaced to an upper position, so that the water flow through the water flow channel 11 is increased by D, As a result, the water flow of the inlet pipe 21 of the hydraulic press 20 is increased, and the water outlet of the hydraulic press 20 is increased. With the control valve 10, after the hydraulic press 20 is started, the water output of the hydraulic press 20 can be matched with the water state of the water supply pipe. When the water supply pipe is in a low water state, the water output of the hydraulic press 20 can be reduced accordingly. After the hydraulic press is started, the pressure of the outlet pipe 22 rapidly rises in a shape of 1 «, which can prolong the operating time of the hydraulic press 20 after it is started, and avoid the frequent start and stop of the water J1S machine 20, so as to save the energy consumption of the hydraulic press 20 purpose. At the same time, when the hydraulic press is in a low water state, the amount of water passing through the pump blades of the hydraulic press 20 is also reduced, so that the load of the hydraulic press 20 is reduced, and the purpose of saving energy consumption of the hydraulic press can be achieved. -10 —
