Description of the invention () Background of the invention: The present invention is a water cavity machine flow regulating device, especially a water supply pipe that can automatically adjust the flow suspension of the water outlet to stabilize the water supply pipe. The water pressure and water consumption of the road can be adjusted by the hydraulic pressure machine's flow regulating device. According to the water supply system used in today's buildings, in order to avoid the momentary pressure of the water pipe being too low or too high, which causes intermittent instability when the water is flowing out of the water, or the sudden 1S force is too large Rapid spraying and splashing, so most of the time a water press is installed on the water supply pipeline to stabilize the water calendar * to keep the water calendar of the water supply pipeline in a certain park. According to the different control methods, the conventional hydraulic press can be roughly divided into constant pressure hydraulic pressure Μ using M frequency converter and frequency conversion motor, and differential pressure hydraulic 压 press using pressure lion to control water pressure 榇 start and stop. The differential pressure type hydraulic pressure pump mainly includes: a hydraulic pressure pump; and a pressure switch, the stress opening relationship is set on the outlet pipe of the hydraulic machine, and the water history of the outlet pipe is sensed by K, and set at a certain pressure Within the Fan Garden, when the user takes water, once the pressure in the water supply line drops to the lower limit of the pressure range set by the pressure switch, the hydraulic press can be controlled to start up and increase the water pressure in the water supply line. After the pipeline pressure rises M, the pressure opening immediately generates another signal to control the hydraulic pump to stop the lotus rotation, so that the water pressure in the water supply pipeline will not continue to rise. And a storage tank, which is set on the outlet pipe of the hydraulic press, can store the water pressure when the water responder is started; and when the water 榇 stops running, the water stored in the storage tank is used to supplement the loss of the water supply pipe. -2- (Please read the precautions on the back before filling this page); Binding. Order 4 This paper size is applicable to China National Standard (CNS) 8 4 specifications (2 丨 0'〆297 mm) 550343 A7 _B7___ V. The invention explains that the amount of water in (), so the pressure in the water supply pipeline will not drop too quickly instantaneously 'to reduce the frequency of hydraulic motor starting. The conventional f variable frequency constant pressure hydraulic press uses a variable frequency motor with a variable speed, and it has a historical force sensing switch, which detects the pressure in the water supply pipeline with M, and installs an inverter based on the pressure. The signal of the magnitude of the water pressure sensed by the sensing switch controls the speed of the motor of the water mist machine to rise or fall, and M will keep the water pressure in the water supply pipeline stable. The comparison between the conventional differential pressure hydraulic press and the frequency conversion hydraulic press is as follows. Because the hydraulic motor of the differential pressure hydraulic press has a fixed speed structure, and the hydraulic pressure is controlled by simply using a pressure switch to control the start or stop of the water calendar motor, so if the water output of the hydraulic pump is greater than the water demand of the water supply pipe If it is measured, the pressure in the water supply pipeline will rise, so that immediately after the hydraulic motor is started, it will stop the lotus rotation immediately, causing the frequency of the hydraulic motor to start and stop too frequently, which will not only cause the power consumption of the hydraulic press. If the amount is too large, it will seriously affect the service life of the hydraulic motor and water appliances. Because the ideal design of the ifcb differential pressure hydraulic press is that the water flow of the hydraulic press is equal to the water output of the water supply pipeline at that time, so that after the water machine is started, the pressure in the water supply pipeline can slowly rise to reach the U1S state, avoiding the hydraulic press. The frequency of motor opening and closing is too frequent, and M and power consumption are too large. However, the speed of the motor of the differential pressure hydraulic press is fixed * Therefore, the water output cannot be changed, and the water consumption of the general apartment Daqing is the most -3-This paper size applies to the Chinese National Standard (CNS) Α4 specification (210X297 mm) " (Please read the precautions on the back before filling out this page) Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs 550343 A7 B7 V. Description of the invention () There will be great differences with time, so water supply system designers In order to meet the water demand during the rush hour, it is necessary to use a water pump with a large water output. But in this way, when the water consumption during the off-peak time is reduced, the average water output of the hydraulic machine will far exceed the water consumption of the user at that time, which not only causes the hydraulic machine to run unsteadily but wastes energy, and affects (1 hydraulic machine motor life, and This makes the water pressure too high and it is not fixed. This: Xibu frequency conversion constant pressure hydraulic machine uses a variable speed variable frequency motor, so the speed of the motor can be reduced when the water consumption is small, and when the water consumption is increased, the motor The rotation speed can be increased, so that the water output of the water calendar machine can be adjusted with the water consumption of the water supply pipeline, so it can avoid the shortcomings of the water machine motor starting and stopping too frequently. However, the conventional frequency conversion constant pressure water calendar machine must be used. The device builds a complex and expensive inverter-type motor, and the cost of the inverter is extremely expensive and requires professional technicians to maintain. The cost of equipment and operation and maintenance costs is greater than that of a differential pressure hydraulic press, which can be burdened by non-general small users. Therefore, only large users will choose to use Hengye inverter hydraulic press. For the above reasons, Xi Obviously, the structure of the hydraulic press needs to be improved. In view of this, the inventors have been thinking hard and researching extreme poles. Based on years of experience in research and development of related products, after continuous testing and improvement, the invention is finally completed. Summary of the invention: The purpose of the present invention is to provide a shortcoming that the frequency of the motor of the J1S differential hydraulic press can be changed too frequently, and K can reach section -4 ^ paper size applies Chinese National Standard (CNS) A4 specification (210 X 297 mm) ) (Please read the precautions on the back before filling out this page) Packing -------- Order i — 丨 # -Printed by the Employees ’Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs Printed by the Employees’ Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs Printed 550343 A7-—__ ^ B7 V.

At this time, the piston group 80 is moved to the left by the elastic force of the spring 84, and at the same time, the left piston group 60 is moved to the left. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs In order to make the spring 85 and the piston group 80 move smoothly, a vent hole 73 is provided in the right seat cover 71. In order to match different models or different water conditions, the right seat cover 71 can be tightened to increase the elasticity or release the elasticity to reduce the elasticity. In the present invention, when the water pressure and the pressure change, the control device II automatically adjusts by applying the element 62 into the flow channel 12, so that the water flow changes after the body 10 passes through the body 10 to meet the actual water demand of the water supply pipeline 5, so The pressure of the water outlet of the water supply pipe 5 is not too large and exceeds the normal use range, which can prevent the instantaneous change of the water pressure of the water supply pipe 5 and cause the hydraulic motor 2 to open and close-8-This paper size applies to Chinese national standards (CNS) A4 specifications (210 X 297 mm) 550343 Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs A7 B7 V. Invention Description () Frequent actions occur. Fig. 2 is a schematic view showing the operation of the present invention, in which the control element 62 is balanced by the interaction of the magic force of the water flowing into the rj guide hole 55 and the elastic force of the spring 85. When the water outlet pressure of the water supply pipe 5 decreases, the pressure of the water flow introduced by the guide hole 55 also decreases. The force acting on the control element 62 becomes / J, and the right end of the control element 62 is relatively subjected to the spring. 85 has a large elastic force and is displaced to the left, so that the position of the control I element 62 extending into the flow channel 12 is reduced, and this pump 3 can flow into a larger amount of water. As shown in FIG. 3, when the water outlet pressure in the water supply pipeline 5 increases, the guide hole 55 introduces a larger water pressure, so the left end of the I control element 62 is displaced to the right, and the I element 62 is controlled to extend into the flow. The increase of the gP level of the channel 12 reduces the cross-sectional area of the flow channel and causes resistance when the water flows through it, so that the water output of the pump 3 is reduced by Xfcb, and accordingly, fewer water outlets are adjusted. Water demand. The above-mentioned implementation actions can be completed quickly. Therefore, in addition to effectively controlling the water consumption of the water outlet of the pump 3 and the water supply pipeline 5 to balance each other, the present invention also avoids the frequent pressure switch 7 caused by the instantaneous change of the water outlet pressure of the water supply pipeline 5. Starting the motor 2 causes the disadvantage of being easily damaged. As shown in Figures 4 to 5, this is the second embodiment of this creation. The main difference from the first embodiment is two points. The first point is that the seat covers 51A and 71A used by it are modified by fitting. The I-frame structure on the outside of the seat body 50 and the seat body 70. The second point is that the guide tube 55A is a pipeline provided at the left base 50 at an external price fl. One end is connected to the water supply pipeline 5 and the other end is connected to a left cover 51A. Above the connecting pipe 53 at the end, due to Xfct: the water flow pressure can be guided from the water supply pipe to the inside of the empty chamber 52. 9- This paper size is applicable to China National Standard (CNS) A4 (210 X 297 mm) ------------- installation -------- order- (please read the back first (Notes for filling in this page)
