Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of valve equipment, in particular to an automatic irrigation PE valve. Background Art
[0002] Irrigation is a technical measure to supplement the water needed by crops. In order to ensure the normal growth of crops and obtain high and stable yields, crops must be supplied with sufficient water. Under natural conditions, the water requirements of crops are often not met due to insufficient precipitation or uneven distribution. Therefore, artificial irrigation must be carried out to make up for the lack of natural rainfall. Irrigation means using water to irrigate the land. The principle of irrigation is that the amount of irrigation, the number of irrigations and the time should be determined according to the water requirements of medicinal plants, the growth stage, the climate and the soil conditions. Irrigation should be timely, appropriate and reasonable. Its types mainly include irrigation before sowing, irrigation for seedling promotion, irrigation during the growth period and irrigation in winter;
[0003] Valves are pipeline accessories used to open and close pipelines, control flow direction, and adjust and control the parameters (temperature, pressure, and flow) of the conveying medium. According to their functions, they can be divided into shut-off valves, check valves, regulating valves, etc. Valves are control components in fluid conveying systems, and have functions such as shut-off, regulation, diversion, prevention of backflow, 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 various valves used in extremely complex automatic control systems. Valves can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal, and radioactive media;
[0004] Most of the existing agricultural irrigation valves are operated manually, and they cannot irrigate and close in real time according to the conditions of the farmland, which affects the growth of crops. At the same time, traditional valves are affected by external corrosion for a long time, which affects irrigation. With the advancement of agricultural modernization, traditional agricultural irrigation methods have been unable to meet the growing needs of agricultural production. The traditional manual operation method is not only inefficient, but also easily affected by human factors, which brings a series of problems to farmland irrigation. In order to solve the above problems, we have carried out research and development of agricultural water-saving automatic irrigation PE valves. Because the water source in farmland irrigation is complex, it contains more impurities, which can easily cause scratches and damage to the seals, and impurities can easily get stuck in the gap and affect the sealing of the valve. Therefore, the utility model proposes an automatic irrigation PE valve to solve the problems existing in the prior art. Utility Model Content

When sealing, the sealing valve 4 rotates to block the water pipe body 1, the first rubber strip 5 presses the first rubber sealing member 2, and the second rubber strip 6 presses the second rubber sealing member 3. When closing, the rubber sealing members are squeezed against each other to produce elastic deformation, and sealing pressure is formed between the deformed rubbers, thereby achieving the effect of valve sealing, ensuring that the valve is in a tightly closed state, and effectively preventing impurities in the water flow from affecting the sealing of the valve.
[0022] The first rubber seal 2 and the second rubber seal 3 are staggered and fixed, and the sealing groove 7 and the sealing strip 8 are embedded in the seal to effectively improve the sealing performance and solve the problem that impurities are easily stuck in the gap and affect the sealing performance of the valve.
[0023] The rotating mechanism includes a through hole 9, a rotating shaft 10, a wrench 11, an annular sealing groove 12 and an annular sealing ring 13. A through hole 9 is opened on the top of the water pipe body 1, and a rotating shaft 10 is fixedly provided in the middle of the sealing valve 4. The upper end of the rotating shaft 10 extends through the through hole 9, and a wrench 11 is fixedly provided on the upper end of the rotating shaft 10. An annular sealing groove 12 is opened around the through hole 9, and an annular sealing ring 13 is fixedly provided on the rotating shaft 10. An automatic control mechanism is provided on one side of the water pipe body 1, and a locking mechanism is fixedly provided on the other side of the water pipe body 1. Two groups of annular sealing grooves 12 are provided, and the annular sealing rings 13 are matched and embedded in the annular sealing grooves 12 for sealing. When opening and closing, the wrench 11 is turned to drive the rotating shaft 10 to rotate, and at the same time drive the annular sealing ring 13 to rotate in the annular sealing groove 12, so that the rotating shaft 10 maintains good sealing performance during rotation.
[0024] The automatic control mechanism includes a bracket 14, a motor 15 and a drive shaft 16. The bracket 14 is fixedly provided on one side of the water pipe body 1, and the motor 15 is fixedly provided on the bracket 14. The output end of the motor 15 is connected to the drive shaft 16, and the lower end of the drive shaft 16 is fixedly connected to the wrench 11. When automatic control is performed, the motor 15 starts and drives the wrench 11 and the rotating shaft 10 to rotate through the drive shaft 16 for adjustment.
[0025] The locking mechanism includes a locking frame 17, a first locking hole 18, a second locking hole 19 and a latch 20. The locking frame 17 is fixedly provided on the other side of the water pipe body 1, the wrench 11 is provided with a first locking hole 18, the locking frame 17 is provided with a second locking hole 19, and a latch 20 is inserted between the first locking hole 18 and the second locking hole 19. The first locking hole 18 and the second locking hole 19 correspond to each other in upper and lower positions. When it is necessary to keep the lock locked to prevent accidental touch, the wrench 11 is rotated to the locked state, and then the latch 20 is passed through the first locking hole 18 and the second locking hole 19 to achieve physical locking.
[0026] When the valve in the automatic irrigation PE valve is closed, the motor starts and drives the wrench and the rotating shaft to rotate forwardly through the driving shaft, driving the sealing valve to rotate 90° in the water pipe body to achieve sealing, so that the first rubber seal fits with the first rubber strip, the second rubber seal fits with the second rubber strip, the sealing strip is embedded in the sealing groove, and the rubber seals squeeze each other to produce elastic deformation to ensure the sealing effect. When the valve needs to be locked, the first locking hole and the second locking hole overlap in the upper and lower positions after the wrench is turned to the closed position, and the pin is inserted into the first locking hole and the second locking hole to lock it to prevent the valve from being displaced and loosened due to external factors. When the rotating shaft rotates, it drives the annular sealing ring to rotate along the annular sealing groove to achieve effective sealing of the through hole. When the valve needs to be opened, the pin is pulled out, and the motor drives the driving shaft and the rotating shaft to reverse, so that the sealing valve rotates 90° in the opposite direction to open.
