Description

Technical Field

[0001] The utility model relates to the technical field of water savers, in particular to an adjustable water saver. Background Art

[0002] A water saver is a device used to reduce water consumption and improve water efficiency, and it is widely used in many fields such as homes and industries. There are many types of water savers, including water-saving faucets, water-saving toilets, water-saving showers, and water-saving washing machines. These devices help households and businesses save water by meeting daily water needs while reducing water consumption.

[0003] The dripper is also a water-saving device. It is widely used in occasions such as plant watering. It reduces evaporation loss and surface runoff by delivering water directly to the roots of plants, thereby significantly improving water utilization and achieving obvious water-saving effects.

[0004] After searching, the Chinese utility model patent with publication number: CN202778758U discloses an adjustable water-saving drip irrigation head, including a water head cap, a plugging piece and a water head core; the water head cap is closed at the top, hollow inside, and has a number of water outlet holes on the side wall; the water head core is in the shape of a "Zhong" character, connected from top to bottom inside, with the bottom end being the water inlet and the top end being the water outlet, and the outer wall in the middle is threadedly connected to the inner wall of the water head cap; the top of the inner cavity of the water head cap is provided with a groove corresponding to the top of the water head core, and the plugging piece is embedded in the groove and sealed above the water outlet of the water head core. The utility model adjusts the distance between the water outlet of the water head core and the plugging piece by tightening or loosening the water head cap on the water head core, thereby adjusting the dripping amount of the drip irrigation head to adapt to the different water requirements of crops and the changes in the geographical location of farmland in mountainous areas, truly achieving the purpose of saving water and improving water utilization efficiency;

[0005] In the above technical solution, the dripping amount is adjusted by adjusting the distance between the water outlet and the sealing piece. However, the above technical solution requires manual adjustment, and the adjustment efficiency is low. When the water pressure changes, automatic adjustment cannot be achieved. When the water pressure is high, the dripping amount cannot be automatically adjusted, which may easily cause an increase in the dripping amount and cause water waste. When the water pressure is low, the dripping amount cannot be automatically adjusted, which will cause insufficient dripping amount and affect the efficiency of drip irrigation. Utility Model Content

[0006] The purpose of the utility model is to provide an adjustable water saver to solve the problems raised in the above background technology.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an adjustable water-saving device, comprising: a threaded male head and a threaded female head, a tee is provided on the top of the threaded female head, an adjusting shell is provided on the top of the tee, a sealing ball seat is provided on the inner wall of the top of the adjusting shell, an adjusting rod is slidably provided inside the tee, a sealing top ball is provided on the top of the adjusting rod, a fixing plate is provided on the outer wall of the upper half of the adjusting rod, a reset spring is provided between the fixing plate and the bottom inner wall of the adjusting shell, an adjusting screw is provided at one end of the tee, a conical fixing seat is provided at one end of the adjusting screw, and the bottom end of the adjusting rod abuts against the outer wall of the conical fixing seat.

[0008] Furthermore, the bottom of the regulating shell is connected to the three-way pipe, the top of the regulating shell is provided with a water outlet head, the top of the water outlet head is provided with a water outlet hole, and the regulating shell is connected to the water outlet head.

[0009] Furthermore, a top rod is provided at the center of the top of the sealing top ball, an anti-blocking rod is provided on the outer wall of the top rod, and one end of the anti-blocking rod is located inside the water outlet.

[0010] Furthermore, a locking nut is provided on the outer side of the adjusting screw, and one side of the locking nut is in contact with one end of the three-way pipe.

[0011] Furthermore, the sealing ball seat is in the shape of a hemispherical shell, a through hole is opened on the top of the sealing ball seat, and the inner diameter of the sealing ball seat is the same as the outer diameter of the sealing top ball.

[0012] Furthermore, guide rods are provided on both sides of the inner wall of the three-way pipe, and the spacing between the guide rods is the same as the bottom diameter of the adjustment rod.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The utility model realizes that when the adjustable water-saving device is used, the water-saving device is installed on the capillary tube for drip irrigation through the connection between the threaded female head and the threaded male head through the three-way pipe, the regulating shell and the sealing top ball. When the water-saving device is used, the water flows into the water outlet through the threaded female head, the three-way pipe and the regulating shell, and finally sprays out from the water outlet hole. When the water flow pressure changes, for example, when the water flow pressure suddenly increases, the water flow will increase the impact force on the sealing top ball, so that the sealing top ball moves upward. At this time, the sealing The gap between the sealing ball and the sealing ball seat becomes smaller, so that the water flow entering the water outlet is reduced, thereby automatically reducing the water output. Conversely, when the water flow pressure becomes smaller, the impact force of the water flow on the sealing top ball becomes smaller. Under the elastic force of the reset spring, the sealing top ball moves downward, so that the gap between the sealing top ball and the sealing ball seat increases, thereby automatically increasing the water output. The drip irrigation water saver automatically adjusts the water output according to the water flow pressure to ensure the stability of the water output, and ensures the water output of drip irrigation when the water pressure is small, and saves water when the water pressure is high.

[0015] In addition, when the water-saving device is in use, the initial deformation of the reset spring can be adjusted by means of an adjusting screw. The adjusting screw is screwed into the interior of the tee so that the truncated cone-shaped fixing seat follows the movement. The inclined surface design of the truncated cone-shaped fixing seat causes the adjusting rod to rise, thereby increasing the tensile deformation of the reset spring and reducing the sensitivity of the water-saving device to changes in water pressure. Conversely, the adjusting screw is screwed outward from the tee so that the tensile deformation of the reset spring decreases. When the water pressure increases or decreases, the reset spring can produce a greater deformation, thereby increasing the stroke of the sealing top ball and increasing the sensitivity of the water-saving device to changes in water pressure.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] See also Figure 1-Figure 4The utility model provides a technical solution: an adjustable water saver, comprising: a threaded male head 1 and a threaded female head 2, a tee 3 is provided on the top of the threaded female head 2, an adjusting shell 6 is provided on the top of the tee 3, a sealing ball seat 14 is provided on the inner wall of the top of the adjusting shell 6, an adjusting rod 10 is provided inside the tee 3 for sliding, a sealing top ball 12 is provided on the top of the adjusting rod 10, a fixing plate 11 is provided on the outer wall of the upper half of the adjusting rod 10, a return spring 13 is provided between the fixing plate 11 and the inner wall of the bottom of the adjusting shell 6, an adjusting screw 4 is provided at one end of the tee 3, a truncated cone type fixing seat 9 is provided at one end of the adjusting screw 4, and the bottom end of the adjusting rod 10 abuts against the outer wall of the truncated cone type fixing seat 9. When the water flow pressure suddenly increases, the water flow will increase the impact force on the sealing top ball 12, causing the sealing top ball 12 to move upward, and at this time, the gap between the sealing top ball 12 and the sealing ball seat 14 becomes smaller, so that the water flow entering the water outlet 7 is reduced, thereby automatically reducing the water output.

[0023] The bottom of the regulating shell 6 is connected with the three-way pipe 3, the top of the regulating shell 6 is provided with a water outlet 7, the top of the water outlet 7 is provided with a water outlet hole 8, and the regulating shell 6 is connected with the water outlet 7. Through the connection between the threaded female head 2 and the threaded male head 1, the water-saving device is installed on the capillary tube for drip irrigation. When the water-saving device is used, water flows into the water outlet 7 through the threaded female head 2, the three-way pipe 3, and the regulating shell 6, and finally sprays out from the water outlet hole 8.

[0024] A push rod 15 is provided at the center of the top of the sealing top ball 12, and an anti-blocking rod 16 is provided on the outer wall of the push rod 15. One end of the anti-blocking rod 16 is located inside the water outlet 8. When the water pressure changes and the sealing top ball 12 rises and falls, the push rod 15 and the anti-blocking rod 16 are driven to rise and fall reciprocally. Through the reciprocating rise and fall of the anti-blocking rod 16, the water outlet 8 is unblocked to prevent the water outlet 8 from being blocked.

[0025] A locking nut 5 is provided on the outside of the adjusting screw 4, and one side of the locking nut 5 abuts against one end of the tee pipe 3. The locking nut 5 is used to lock and fix the rotation position of the adjusting screw 4 to prevent the adjusting screw 4 from being rotated arbitrarily by external force.

[0026] The sealing ball seat 14 is in the shape of a hemispherical shell, and a through hole is opened on the top of the sealing ball seat 14. The inner diameter of the sealing ball seat 14 is the same as the outer diameter of the sealing top ball 12. When the gap between the sealing top ball 12 and the sealing ball seat 14 increases, the water output increases under the same water pressure. When the gap between the sealing top ball 12 and the sealing ball seat 14 decreases, the water output decreases under the same water pressure. When the sealing top ball 12 and the sealing ball seat 14 fit together, the top of the adjustment shell 6 is sealed, and the water economizer is closed and no water is discharged.

[0027] Guide rods 17 are arranged on both sides of the inner wall of the tee pipe 3, and the spacing between the guide rods 17 is the same as the bottom diameter of the adjusting rod 10. The lifting and lowering of the adjusting rod 10 is guided by the guide rods 17, thereby improving the lifting and lowering stability of the adjusting rod 10.

[0028] When the adjustable water-saving device is used, the water-saving device is installed on the capillary tube for drip irrigation through the connection between the threaded female head 2 and the threaded male head 1. When the water-saving device is used, water flows through the threaded female head 2, the three-way pipe 3, and the regulating shell 6 into the water outlet 7, and finally sprays out from the water outlet 8. When the water flow pressure changes, for example, when the water flow pressure suddenly increases, the water flow will increase the impact force on the sealing top ball 12, so that the sealing top ball 12 moves upward, and at this time, the sealing top ball 12 and the sealing ball seat 14 are spaced apart. The gap becomes smaller, so that the water flow entering the water outlet 7 is reduced, thereby automatically reducing the water output. On the contrary, when the water flow pressure becomes smaller, the impact force of the water flow on the sealing top ball 12 becomes smaller. Under the elastic force of the reset spring 13, the sealing top ball 2 moves downward, so that the gap between the sealing top ball 12 and the sealing ball seat 14 increases, thereby automatically increasing the water output. In this way, the drip irrigation water saver automatically adjusts the water output according to the water flow pressure to ensure the stability of the water output, and ensures the water output of drip irrigation when the water pressure is small, and saves water when the water pressure is high.

[0029] In addition, when the water-saving device is in use, the initial deformation of the reset spring 13 can be adjusted by the adjusting screw 4. The adjusting screw 4 is screwed into the inside of the tee pipe 3 so that the truncated cone fixing seat 9 follows and moves forward. The inclined surface design of the truncated cone fixing seat 9 causes the adjusting rod 10 to rise, thereby increasing the tensile deformation of the reset spring 13 and reducing the sensitivity of the water-saving device to changes in water pressure. Conversely, the adjusting screw 4 is screwed out toward the outside of the tee pipe 3, and the tensile deformation of the reset spring 13 is reduced. When the water pressure increases or decreases, the reset spring 13 can produce a larger deformation, thereby increasing the stroke of the sealing top ball 12 and improving the sensitivity of the water-saving device to changes in water pressure.

[0030] Based on the embodiments of the present utility model, all other embodiments obtained by ordinary technicians in the field without making any creative work shall fall within the scope of protection of the present utility model.
