Description

Technical Field

[0001] The invention relates to the field of water purifiers, and in particular to an anti-blocking structure of a flow regulating device of a concentrated water regulating valve. Background Art

[0002] The concentrate regulating valve is a commonly used device in water treatment systems. It is mainly used to control the flow and pressure of concentrate water. The working principle of the concentrate regulating valve is based on the principle of fluid mechanics. It adjusts the resistance of the fluid by changing the opening of the valve, thereby achieving control of the flow and pressure. When the valve opening is small, the resistance of the fluid passing through the valve is large, and the flow and pressure are reduced accordingly; when the valve opening is large, the resistance of the fluid passing through the valve is reduced, and the flow and pressure will increase.

[0003] In the field of membrane filtration water treatment, membrane filtration adopts cross-flow filtration, and the flow rate of cross-flow filtration often needs to be adjusted by a brine regulating valve. The existing brine regulating valve technology is difficult to solve the problem of brine valve scaling or blockage caused by foreign matter; in addition, when the valve body is discharging water, the water pressure at the outlet changes due to changes in water flow and flow rate. When the water pressure is high, it is easy to squeeze the parts at the outlet and increase friction, thereby shortening their service life.

[0004] Therefore, an improvement is made and an anti-clogging structure of a flow regulating device of a concentrated water regulating valve is proposed. Summary of the invention

[0058] Furthermore, a cylindrical rod 7 is fixedly connected to the upper surface of the regulating valve core 5 , and the upper end of the cylindrical rod 7 is threadedly connected to the lower end of the connecting rod 104 .

[0059] Furthermore, the diameter of the water inlet hole B402 is greater than that of the water inlet hole A401, and a surface A 8 is formed at the connection between the water inlet hole B402 and the water inlet hole A401, and the surface A 8 is conical.

[0060] Furthermore, the diameter of the regulating valve core 5 is larger than that of the cylindrical rod 7 and a C-surface 9 is formed at the connection between the regulating valve core 5 and the cylindrical rod 7, and the C-surface 9 is conical.

[0061] Furthermore, the water inlet hole A401, the water inlet hole B402, the water inlet hole C6 and the water inlet hole D601 are circular holes, and the water outlet hole 602 is a square hole.

[0062] The adjusting nut 502 is connected to the valve body 113 through a threaded structure, wherein the length of the threaded hole of the valve body 113 is longer than the length of the thread on the adjusting nut 502; a cylindrical rod 7 is provided on the adjusting valve core 5, and after the adjusting valve core 5 is installed in the valve body 113, the cylindrical rod 7 on the adjusting valve core 5 is inserted into the hole A of the valve body 113, and a spring 501 is provided between the adjusting valve core 5 and the adjusting nut 502, one end of the spring 501 is inserted into the cylindrical boss of the adjusting valve core 5, and the other end is inserted into the boss of the adjusting nut 502. Under the action of the spring 501, In the initial state, the conical C surface 9 and D surface of the regulating valve core 5 are respectively in close contact with the conical A surface 8 and B surface of the valve body 113. The adjusting nut 502 is provided with a hole C, a hole D and a square hole. The hole C, the hole D and the square hole are connected. The square hole can be conveniently used to use a square tool to rotate and adjust the adjusting nut 502. When water enters the water inlet end of the regulating valve, the regulating valve core 5 moves downward under the push of the water pressure, and the distance between the C surface 9 and the D surface on the regulating valve core 5 and the A surface 8 and the B surface corresponding to the valve body 113 is correspondingly increased, and then discharged from the square hole. When the water pressure at the water inlet end of the regulating valve decreases, the regulating valve core 5 moves upward, and the C surface 9 and D surface on the regulating valve core 5 correspond to the A surface 8 of the valve body 113. When the pressure at the water inlet end disappears, the regulating valve core 5 returns to its initial state. The regulating nut 502 can be rotated through the water outlet hole 602 on the regulating nut 502 with a square tool to adjust the distance between the regulating nut 502 and the regulating valve core 5. The smaller the distance, the greater the elastic force generated by the spring 501 between the adjusting nut 502 and the regulating valve core 5. Under the same water pressure, the smaller the distance the regulating valve core 5 moves, the smaller the flow rate of water discharged from the regulating valve.

[0063] The use process of the anti-blocking structure of the flow regulating device of the concentrated water regulating valve provided by the present invention is as follows:

[0064] When adjusting the length of the water outlet position, the movable rod 101 can be slid so that the connecting block 105 on its surface is engaged with the block 103, and then the handle 1 is rotated. During the rotation, the handle 1 drives the block 103 and the connecting rod 104 fixedly connected to the block 103 to rotate. During the rotation, the connecting rod 104 drives the gear 1 106 to rotate. The rotation of the gear 1 106 drives the rotation of the gear 2 107. During the rotation of the gear 2 107, the pull rope 109 fixedly connected to the groove 108 of the gear 2 107 contracts. During the contraction of the pull rope 109, the movable ring 110 is driven to move. During the movement, the movable ring 110 drives the telescopic tube 111 to extend and retract. The extension and retraction of the telescopic rod can adjust the space size of the water outlet position, thereby realizing the adjustment of the water pressure.

[0065] The adjusting nut 502 is connected to the valve body 113 through a threaded structure, wherein the length of the threaded hole of the valve body 113 is longer than the length of the thread on the adjusting nut 502; a cylindrical rod 7 is provided on the adjusting valve core 5, and after the adjusting valve core 5 is installed in the valve body 113, the cylindrical rod 7 on the adjusting valve core 5 is inserted into the hole A of the valve body 113, and a spring 501 is provided between the adjusting valve core 5 and the adjusting nut 502, one end of the spring 501 is inserted into the cylindrical boss of the adjusting valve core 5, and the other end is inserted into the boss of the adjusting nut 502. Under the action of the spring 501, In the initial state, the conical C surface 9 and D surface of the regulating valve core 5 are respectively in close contact with the conical A surface 8 and B surface of the valve body 113. The adjusting nut 502 is provided with a hole C, a hole D and a square hole. The hole C, the hole D and the square hole are connected. The square hole can be conveniently used to use a square tool to rotate and adjust the adjusting nut 502. When water enters the water inlet end of the regulating valve, the regulating valve core 5 moves downward under the push of the water pressure, and the distance between the C surface 9 and the D surface on the regulating valve core 5 and the A surface 8 and the B surface corresponding to the valve body 113 is correspondingly increased, and then discharged from the square hole. When the water pressure at the water inlet end of the regulating valve decreases, the regulating valve core 5 moves upward, and the C surface 9 and D surface on the regulating valve core 5 correspond to the A surface 8 of the valve body 113. When the pressure at the water inlet end disappears, the regulating valve core 5 returns to its initial state. The regulating nut 502 can be rotated through the water outlet hole 602 on the regulating nut 502 with a square tool to adjust the distance between the regulating nut 502 and the regulating valve core 5. The smaller the distance, the greater the elastic force generated by the spring 501 between the adjusting nut 502 and the regulating valve core 5. Under the same water pressure, the smaller the distance the regulating valve core 5 moves, the smaller the flow rate of water discharged from the regulating valve.
