[0026] EMBODIMENT

[0027] As Figures 1-4As shown, a flow regulating valve with locking sleeve, comprising upper shell 2, lower shell 3, knob 1 and locking sleeve 8, knob 1 is installed between upper shell 2 and lower shell 3, locking sleeve 8 is installed on the upper part of knob 1, first inner sealing ring 4 is installed on the lower part of knob 1, inner sealing gasket 6 is arranged at the connection between knob 1 and upper shell 2 and lower shell 3, second inner sealing ring 5 is arranged at the connection between upper shell 2 and inner sealing gasket 6.

[0028] Two groups of outer sealing rings 3 are arranged at the connection between upper shell 2 and lower shell 3, two groups of inner sealing gaskets 6 are arranged, the connection between two groups of inner sealing gaskets 6 and knob 1 is arc-shaped 61, two groups of inner sealing gaskets 6 are provided with clamping grooves 62 on the outer side, when inner sealing gasket 6 is assembled with upper shell 2 and lower shell 3, upper shell 2 and lower shell 3 are clamped into the inner part of clamping groove 62.

[0029] Knob 1 comprises rotating part 10, indicating part 11 and connecting part 12, connecting part 12 is installed below rotating part 10, indicating part 11 is clamped in the inner part of rotating part 10, the top of rotating part 10 is provided with locking groove 103, the lower side of locking sleeve 8 is provided with locking plate 81 corresponding to locking groove 103.

[0030] Upper shell 2 further comprises clamping part 21, clamping part 21 is provided with groove corresponding to the protrusion at the connection with lower shell 3, one end of rotating part 10 is provided with indicator 101, the other end is provided with adjusting handle 102, connecting part 12 and inner sealing gasket 6 are provided with flow guide holes 120 of the same size.

[0031] First, the locking sleeve 8 is lifted upward, so that the locking plate 81 is separated from the locking groove 103 at the top of the rotating part 10, and the knob 1 is easily unlocked. Then, the adjusting handle 102 at one end of the rotating part 10 is used to conveniently rotate the knob, so as to change the size of the fluid passage and realize accurate flow regulation. After the adjustment is completed, the locking sleeve 8 is pushed back down, the locking plate 81 is clamped into the locking groove 103 again, the knob 1 is reliably locked, effectively avoiding accidental rotation of the knob due to external factors such as vibration, accidental touch, etc., and ensuring the stability and durability of the flow regulation.

[0032] The first inner sealing ring 4 at the lower part of the knob 1 can effectively prevent fluid from leaking from the connection between the knob and the lower part. The inner sealing gasket 6 at the connection between the knob 1 and the upper housing 2 and the lower housing 3, in combination with the second inner sealing ring 5 at the connection between the upper housing 2 and the inner sealing gasket 6, greatly enhances the sealing between the upper and lower housings and the knob. In addition, the two sets of outer sealing rings 3 at the outer side of the upper housing 2 further ensure the sealing between the entire regulating valve and the external environment. Furthermore, the unique design of the inner sealing gasket 6, with the arc-shaped 61 at the connection between the two sets of inner sealing gaskets and the knob 1 and the outer side provided with a clamping groove 62, the inner side of the upper housing 2 and the lower housing 3 are clamped into the inner clamping groove 62 during assembly, the arc-shaped design can better adapt to the rotation of the knob, and the clamping groove makes the connection more compact, further reducing the risk of leakage, and ensuring the sealing of fluid transportation in all directions, improving the efficiency and safety of transportation.

[0033] The main components of the flow regulating valve, such as the knob 1, the upper housing 2, the lower housing 3, and the locking sleeve 8, are all formed by injection molding, ensuring high precision and efficiency in production. In terms of assembly, a sub-assembly assembly method is adopted, the first inner sealing ring 4 is assembled with the knob to form a knob sub-assembly, the second inner sealing ring 5 and the outer sealing ring 7 are assembled with the upper housing 2 to form an upper housing sub-assembly, then the inner sealing gasket 6, the knob sub-assembly, the lower housing 3, and the upper housing sub-assembly are assembled to form a housing sub-assembly, and finally the housing sub-assembly is assembled with the locking sleeve 8 to form the flow regulating valve assembly. This step-by-step and modular assembly process greatly simplifies the assembly process, reduces the assembly difficulty, improves the production efficiency, and is conducive to large-scale industrial production.

[0034] When two independent pipelines need to be connected, the opening on the knob 1 is in communication with the inner cavity of the housing, at this time the fluid can smoothly pass through the regulating valve, realizing normal transportation between the two pipelines and ensuring the normal operation of the system.

[0035] When it is necessary to adjust the flow size or close the channel, first, the operator lifts the locking sleeve 8 upward to release the locking of the locking plate 81 to the top locking groove 103 of the rotating part 10, unlocking the knob 1. Then, by holding the adjusting handle 102 at one end of the rotating part 10, the knob 1 is rotated. During rotation, the relative positions of the knob 1 and the inner sealing gasket 6 and other components change, and because the connecting part 12 and the inner sealing gasket 6 are provided with flow guide holes 120 of the same size, the change in the positions of these components adjusts the coincidence degree between the flow guide holes 120, etc., thereby changing the size of the channel through which the fluid passes, realizing accurate adjustment of the flow. When the desired flow state is reached or the channel needs to be closed, the locking sleeve 8 is pushed back down, so that the locking plate 81 is clamped into the locking groove 103 again, locking the knob 1 in the current position, ensuring that the knob will not rotate unnecessarily in subsequent work, maintaining the set flow state or closed state.

[0036] When the valve needs to be opened to allow fluid communication, first, the locking sleeve 8 is unlocked to release the locking of the knob 1. Then, the knob 1 is rotated, and the connecting part 12 rotates with the knob. Because the connecting part 12 and the inner sealing pad 6 are provided with flow guide holes 120 of the same size, at the initial stage of rotation, the originally possibly partially misaligned flow guide holes 120 begin to gradually align. As the knob 1 continues to rotate, the relative position of the connecting part 12 and the inner sealing pad 6 changes constantly, and the overlapping area of the flow guide holes 120 gradually increases. In this process, the inner sealing pad 6 can well adapt to the rotation of the knob due to the arc-shaped 61 connection between the knob 1 and the inner sealing pad 6, and the outer clamping groove 62 tightly clamps the inner side of the upper housing 2 and the lower housing 3, maintaining a stable sealing state. Until the flow guide holes 120 completely overlap, at this time, the fluid can pass through the flow guide holes 120 on the connecting part 12 and the inner sealing pad 6 without any obstruction, realizing the complete opening of the valve, and the smooth flow of the fluid.

[0037] When the valve needs to be closed or the flow rate needs to be adjusted, the operation process is reversed. First, the knob 1 is unlocked, and the knob 1 is rotated to rotate the connecting part 12. With the rotation, the overlapping area of the connecting part 12 and the flow guide holes 120 of the inner sealing pad 6 gradually decreases. The inner sealing pad 6 still relies on the arc-shaped 61 connection structure to maintain a stable and good sealing state during the rotation of the knob. When the overlapping area of the flow guide holes 120 decreases to a certain extent, the flow rate decreases accordingly; if it continues to rotate until the flow guide holes 120 are completely misaligned, the valve is closed at this time, and the fluid cannot pass through. After the adjustment is completed, the locking sleeve 8 is pushed back to the locked position, so that the knob 1 cannot be rotated again, the relative position of the connecting part 12 and the inner sealing pad 6 is fixed, and the current flow rate state or closed state is maintained.

[0038] A set of strict and multi-level sealing system is constructed inside the flow regulating valve. At the connecting part between the core knob 1 and the housing, first, the first inner sealing ring 4 installed at the lower part of the knob 1 can effectively block the leakage of fluid from the junction between the knob and the lower part. Secondly, the inner sealing pad 6 is provided between the knob 1 and the upper housing 2 and the lower housing 3, and at the same time, the second inner sealing ring 5 is provided at the connecting part between the upper housing 2 and the inner sealing pad 6. The three are closely matched, greatly enhancing the sealing between the knob and the housing. And at the outside joint of the upper housing 2, the two groups of outer sealing rings 3 are specially set, which provides a solid guarantee for the isolation of the entire regulating valve and the external environment, and completely eliminates any possible leakage path, ensuring that the fluid does not leak at all during transportation, significantly improving the safety and stability of fluid transportation.

[0039] When the flow regulation is completed, the expected flow state is reached or the passage needs to be closed, the operator only needs to push the locking sleeve 8 back to the original position, and the locking plate 81 will be firmly re-inserted into the locking groove 103, thereby firmly locking the knob 1. The design of this locking mechanism is extremely critical, which can effectively avoid the accidental rotation of the knob due to vibration during equipment operation, accidental touch of surrounding personnel and various external factors. In this way, the stability and durability after flow regulation are ensured, providing strong protection for the stable operation of the entire fluid conveying system.
