[0032] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments, so that those skilled in the art can implement it based on the description.

[0033] It should be understood that terms such as “having,” “comprising,” and “including” as used herein do not exclude the presence or addition of one or more other elements or combinations thereof.

[0034] like Figures 1-5 As shown, the present invention provides a manual two-way regulating valve with high adjustment accuracy, comprising: a valve body 1, and two flow measurement sensors 3 arranged on both sides of the valve body 1. The valve body 1 has two ports, wherein the left end is the inlet end and the right end is the outlet end. The two flow measurement sensors 3 are respectively close to the inlet end and the outlet end, and the flow measurement sensors 3 detect the flow rate of the medium passing through the valve body 1.

[0035] A valve cover 21 is installed at the bottom of the valve body 1. The bottom of the valve cover 21 protrudes downward. Fixing holes 18 are provided between the valve cover 21 and the valve body 1. Vertical bolts 19 are installed in the fixing holes 18. A lower nut 20 is fixed to the lower end of the vertical bolts 19. The valve cover 21 is fixed to the bottom of the valve body 1 by the vertical bolts 19 and the lower nut 20. A flat sealing ring 22 is also installed on the end face of the valve cover 21 to further prevent the media from leaking.

[0036] like Figure 1 As shown, in this invention, a handwheel mechanism is installed at the upper end of the valve body 1, and an internal adjustment mechanism is provided inside the valve body cavity 101. The handwheel mechanism is connected to the internal adjustment mechanism, which in turn drives the internal adjustment mechanism inside the valve body cavity 101 to move up and down. The internal adjustment mechanism has the characteristics of simple and compact structure, reasonable design, safety and reliability, and low overall cost. This makes the design of the manual two-way regulating valve effectively eliminate the unbalanced force generated by the pressure difference between the inlet and outlet media on the valve core. It has high adjustment accuracy, small adjustment torque, does not require electric or pneumatic energy, and can adapt to narrow and harsh installation environments.

[0037] Specifically, to achieve the above objectives, the handwheel mechanism provided in this invention includes a handwheel shaft 10 and a handwheel cover 11. An upper inner cavity 102 is mounted on the valve body 1, and the handwheel shaft 10 is installed through and within the upper inner cavity 102. A limiting nut 5 is installed at the lower part of the upper inner cavity 102, thereby restricting the handwheel shaft 10 within the upper inner cavity 102. To prevent leakage between the handwheel shaft 10 and the upper inner cavity 102, a plurality of first O-rings 8 are provided between the handwheel shaft 10 and the upper inner cavity 102. The handwheel shaft 10 has a plurality of grooves, and the plurality of first O-rings 8 are installed in the plurality of grooves from top to bottom to form a sealed connection.

[0038] The lower end of the hand wheel shaft 10 is connected with the inner adjusting mechanism, and the hand wheel cover 11 is installed on the upper end of the hand wheel shaft 10, so that the operator can drive the inner adjusting mechanism to rotate by rotating the hand wheel shaft 10, so as to facilitate the flow of medium in the valve body 1;

[0039] Further, the inner adjusting mechanism comprises a valve rod 12, a piston cylinder 13 and a piston body 16. Specifically, the piston cylinder 13 is installed in the valve body cavity 101 as the main blocking component of the inner adjusting mechanism.

Correspondingly, the lower end of the piston cylinder 13 is in sealing connection with the lower end of the valve body cavity 101, and a fourth O-ring 104 is installed therebetween. The piston body 16 is movably installed in the piston cylinder 13. When the piston body 16 is closed in the piston cylinder 13, the piston cylinder 13 is in sealing connection with the valve body cavity 101 through the third O-ring 103 and the fourth O-ring 104, and no leakage occurs.

[0040] Meanwhile, a second O-ring 15 is also installed in the inner wall of the upper end of the piston cylinder 13. When the piston body 16 is closed in the piston cylinder 13, the second O-ring 15 is exactly sleeved in the piston body 16, so that the piston body 16 is in sealing connection with the piston cylinder 13.

[0041] The valve rod 12 penetrates the bottom of the piston body 16 and is connected with a piston bottom plate 17. The upper end of the valve rod 12 extends upward into the upper inner cavity 102 and is screwed into the inner thread of the hand wheel shaft 10. When the hand wheel shaft 10 rotates, the valve rod 12 is driven to rotate and move upward or downward, so that the piston body 16 is opened or closed in the piston cylinder 13.

[0042] A plurality of inner wall flow-through holes 131 are arranged on the piston cylinder 13. Correspondingly, a plurality of outer wall flow-through holes 161 are arranged on the piston body 16. An upper inclined surface 162 is arranged on the upper part of the outer wall flow-through hole 161, and a lower inclined surface 132 is arranged on the lower part of the inner wall flow-through hole 131. When the piston body 16 moves downward to the lowermost position, the upper inclined surface 162 contacts the lower inclined surface 132, so that the upper inclined surface 162 and the lower inclined surface 132 are in hard sealing connection.

[0043] The distance between the upper wall of the outer wall flow-through hole 161 and the piston bottom plate 17 is H2, and the maximum stroke of the valve rod 12 moving upward in the hand wheel shaft 10 is H1. H1 is set to be equal to H2, so as to ensure that the flow is maximum when the hand-operated two-way regulating valve is fully opened, and the regulating performance of the hand-operated two-way regulating valve is improved.

[0044] Through the design of the above structure, the manual two-way regulating valve has the characteristics of simple and compact structure, reasonable design, safety and reliability, and low comprehensive cost, so that the design of the manual two-way regulating valve effectively eliminates the unbalanced force generated by the inlet and outlet medium pressure difference on the valve core, and has high regulating precision and small regulating operation torque, without the need of electricity and pneumatic energy, and can adapt to narrow and harsh installation environment.
