[0002] Valves are control components in fluid delivery systems and have functions such as shutoff, regulation, diversion, backflow prevention, pressure stabilization, diversion or overflow pressure relief. Valves used in fluid control systems come in a wide variety of varieties and specifications, from the simplest shut-off valves to the various valves used in extremely complex automatic control systems. During the use of valves, water hammer effect often occurs when opening or closing. Therefore, it is necessary to use an energy-saving intelligent electric valve that can prevent water hammer for long-distance water delivery.

The current valve closing generally relies on manual experience, and the valve closing rate cannot be accurately adjusted in time, and the water hammer effect cannot be reduced in time. Most of the current water hammer prevention devices fail to fully utilize the energy of water hammer, resulting in energy waste. There is an urgent need for energy-saving devices that can utilize water hammer energy. Utility Model Content

[0024] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0025] The utility model provides Figure 1-Figure 4 The energy-saving intelligent electric valve for long-distance water delivery and water hammer prevention shown in the figure includes: a pressure relief valve 1, one side of the pressure relief valve 1 is fixedly connected to a water inlet pipe 4, the front side of the pressure relief valve 1 is fixedly connected to a pressure sensor 5, the pressure sensor 5 can detect the real-time water pressure and transmit the data signal to the controller, the controller controls the motor speed on the electric control valve 2 according to a preset program, so as to actively alleviate the water hammer effect generated when the valve is closed; a pressure relief pipe 6, the pressure relief pipe 6 is fixedly connected to the top of the pressure relief valve 1, the rear side of the pressure relief pipe 6 is fixedly connected to a mounting platform 7, the mounting platform 7 is used to facilitate the installation of an electromagnetic generator 8. The mounting platform 7 is fixedly connected with the electromagnetic generator 8, and the electromagnetic generator 8 is electrically connected to the battery and the controller; the electric control valve 2 is fixedly connected to one side of the pressure relief valve 1 through a pipeline. The electric control valve 2 is an existing mature technology. The opening and closing of the valve is controlled by a motor and a transmission structure such as a worm gear. The other side of the electric control valve 2 is fixedly connected with a drainage pipe 3; a pressure relief component, which is installed on the inner side of the pressure relief pipe 6. The pressure relief component is used to reduce water hammer and provide power for the input end of the electromagnetic generator 8.

[0026] Furthermore, the pressure relief assembly also includes a convex ring 9 fixedly connected to the upper and lower sides of the inner side of the pressure relief pipe 6, a spring 10 is arranged between the two convex rings 9, the spring 10 is used to reset the plugging plate 11, and the convex ring 9 is used to limit the plugging plate 11 and the spring 10. The pressure relief assembly also includes a plugging plate 11 slidably installed on the inner side of the pressure relief pipe 6, the top of the plugging plate 11 is rotatably connected to a rotating rod 12, one end of the rotating rod 12 is rotatably connected to a crank 13, and the rear side of one end of the crank 13 is fixedly connected to a ratchet 14, the rotating rod 12 and the crank 13 are used to convert the linear motion of the plugging plate 11 into the rotational motion of the output end of the electromagnetic generator 8, the pressure relief assembly also includes a connecting shaft 15 fixedly connected to the output end of the electromagnetic generator 8, one end of the connecting shaft 15 is provided with a circular hole, the circular hole is used to install a ratchet 16 and a spring 17, and the circular hole is used to install a ratchet 16 and a spring 17. The four corners of one side of the hole are rotatably connected with a pawl 16, and the inner wall of the circular hole is fixedly connected with a spring piece 17. The pawl 16 conflicts with the outer side of the ratchet 14. The ratchet 14, the pawl 16 and the spring piece 17 cooperate to realize that when the crank 13 rotates clockwise, the output end of the electromagnetic generator 8 drives the output end of the electromagnetic generator 8 to rotate and generate electricity. When the crank 13 is reset counterclockwise, the output end of the electromagnetic generator 8 and the connecting shaft 15 no longer rotate with it to avoid the forward and reverse rotation of the output end of the electromagnetic generator 8, so that the electromagnetic generator 8 can generate electricity with the movement of the blocking plate 11. It should be noted that the stroke is short and the amount of electricity that can be generated is limited. Therefore, the electromagnetic generator 8 and the battery and other structures provide auxiliary power supply to the valve, which is used for the emergency needs of the valve in the event of an external power outage. The valve also needs to be equipped with a main power supply to meet normal power supply needs.

[0027] Furthermore, a support sleeve 18 is fixedly connected to one side of the inner side of the pressure relief pipe 6, and the connecting shaft 15 is rotatably installed on the outer side of the support sleeve 18. Reinforcing ribs are evenly distributed on the outer side of the support sleeve 18. The support sleeve 18 is used to support the connecting shaft 15 to improve transmission stability.

[0028] Furthermore, a rotating hole is provided on one side of the circular hole facing inward, and a rotating shaft is fixedly connected to the side close to the ratchet 14 , and the rotating shaft is rotatably mounted on the inner side of the rotating hole. The rotating shaft and the rotating hole cooperate to position and support the rotation of the crank 13 .

[0029] Furthermore, the crank 13 is provided with a strip groove for reducing the amount of material used. Both end surfaces of the crank 13 are arc surfaces. The strip groove is used to reduce the material cost.

[0030] Furthermore, a connecting block is fixedly connected to the top of the blocking plate 11, a fixing hole is opened on the connecting block, and the connecting block and the adjacent end of the rotating rod 12 are rotatably connected through an axle. The cooperation of the connecting block, the fixing hole and the axle facilitates the installation of the rotating rod 12 and the blocking plate 11.

[0031] Furthermore, the pressure sensor 5 is electrically connected to the battery and the controller, and the controller is also electrically connected to the electric control valve 2. When the pressure sensor 5 detects a sudden change in pipeline pressure, it transmits a signal to the controller in a timely manner and adjusts the closing rate of the electric control valve 2 through the controller, thereby being able to actively and effectively reduce the generation of water hammer from the source, rather than just passive water hammer protection.

[0032] When in use, the valve is connected to an external power supply. When closing the valve, the controller controls the electric control valve 2 to start. Due to the change in flow, a water hammer effect is generated in the pipeline. The increased water pressure pushes the plug 11 to compress the spring 10 to move, and the crank 13 is driven to rotate through the rotating rod 12. The ratchet 14 presses against the pawl 16 to drive the connecting shaft 15 and the output end of the electromagnetic generator 8 to rotate to generate electricity. The generated electrical energy is stored in the battery. At the same time, the pressure sensor 5 detects the sudden change in pressure and sends a signal to the controller. The controller controls the motor on the electric control valve 2 to adjust the valve closing rate according to the preset program.

[0033] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
