The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0024] Example 1

[0025] A preferred embodiment of a double valve core regulating valve provided by the present utility model is as follows: Figure 1-4 As shown: A double-spool regulating valve includes a valve body 1, one side of the valve body 1 is connected to a liquid inlet pipe 2, the other side of the valve body 1 is connected to a liquid outlet pipe 3, a valve cover 4 is provided on the top of the valve body 1, and a slot is provided on the top of the valve cover 4. Threaded holes are equidistantly provided on the surfaces of the valve body 1 and the valve cover 4, and bolts 5 are threadedly connected to the inner walls of the threaded holes. An adjusting component 6 and a sealing component 7 are provided inside the valve body 1.

[0026] The concave threaded seat 611 is fixedly mounted on the top of the valve cover 4 ; the threaded fixing sleeve 6112 is fixedly mounted on the bottom of the inner wall of the valve body 1 ; and the clamping frame 6113 is arranged inside the valve body 1 .

[0027] The inner wall of the concave threaded seat 611 is threadedly connected to a screw rod 612, one end of which is fixedly connected to a regulating valve 613, and the other end of the screw rod 612 extends to the interior of the slot hole, and waterproof sleeves 614 are evenly and equidistantly arranged between the inner walls of the slot hole, and the other end of the screw rod 612 is fixedly connected to a rotating rod 615, and the other end of the rotating rod 615 passes through the surface of the waterproof sleeve 614, the interior of the valve cover 4 and extends to the interior of the valve body 1.

[0028] The outer fixed sleeve of the rotating rod 615 is provided with a circular ring sleeve 616, and the outer wall movable sleeve of the rotating rod 615 is provided with a spring 617. One end of the spring 617 is fixedly connected to the surface of the valve cover 4, and the other end of the spring 617 is fixedly connected to the surface of the circular ring sleeve 616. The outer wall equidistant fixed sleeve of the rotating rod 615 is provided with a layered sealing sleeve 618, and the outer wall equidistant fixed sleeve of the rotating rod 615 is provided with a valve core 619. The top of the valve core 619 is in contact with the bottom of the layered sealing sleeve 618.

[0029] The other end of the rotating rod 615 is fixedly connected to the second screw 6111, and the other end of the second screw 6111 extends to the interior of the threaded fixing sleeve 6112, and the outer wall of the second screw 6111 is threadedly connected to the inner wall of the threaded fixing sleeve 6112.

[0030] In this example, the valve core is opened and closed simultaneously by setting the adjustment component 6, and the rotating regulating valve 613 drives the screw 1 612 to rotate. The screw 1 612 is threadedly connected with the concave threaded seat 611 and then rises. The screw 1 612 drives the rotating rod 615 to rotate and rise. At the same time, the rotating rod 615 drives the screw 2 6111 at the other end to rotate and slowly rise from the fixed threaded sleeve 6112. The rotating rod 615 recovers the spring 617 through the annular sleeve 616. After the rotating rod 615 rises, it drives the layered sealing sleeve 618 and the valve core 619 to rise. The layered sealing plate 618 and the valve core 619 are respectively separated from the layered clamping plate 6114, thereby achieving the effect of precise adjustment.

[0031] Example 2

[0032] On the basis of Example 1, a preferred embodiment of a dual valve core regulating valve provided by the present invention is as follows: Figure 1-4 As shown: the sealing assembly 7 specifically includes: a partition 711, which is fixedly installed on both sides of the inner wall of the clamping frame 6113; a spring fixing seat 714, which is fixedly installed on both sides of the inner wall of the clamping frame 6113; and a groove plate 718, which is fixedly installed at equal distances on both sides of the inner wall of the clamping frame 6113.

[0033] An isolation clamping plate 712 is provided at the bottom of the partition 711, and a waterproof rubber strip 713 is fixedly installed on the surface of the isolation clamping plate 712. The surface of the waterproof rubber strip 713 is engaged with the outer wall of the rotating rod 615. A compression spring 715 is fixedly installed inside the spring fixing seat 714. The other end of the compression spring 715 is fixedly connected to an L-shaped pushing block 716. The surface of the L-shaped pushing block 716 is fixedly connected to the bottom of the isolation clamping plate 712.

[0034] The two sides of the L-shaped pushing block 716 are fixedly connected with sliders 717, the outer wall of the slider 717 is slidably connected to the inner wall of the groove plate 718, and the bottom of the L-shaped pushing block 716 is fixedly connected with a driving bevel block 719, and the surface of the driving bevel block 719 is in contact with the surface of the layered sealing sleeve 618.

[0035] In this example, the water source inside the clamping frame 6113 is secondary isolated by setting a sealing component 7. When the rotating rod 615 rises, the layered sealing plate 618 will drive the driving inclined block 719 to extend upward and slowly extend to both sides. The driving inclined block 719 drives the L-shaped pushing block 716 and the isolation clamping plate 712 to move in conjunction. The L-shaped pushing block 716 slides on the groove plate 718 through the slider 717, and after extending to both sides, the compression spring 715 is recovered. After the rotating rod 615 is rotated and closed, the compression spring 715 rebounds quickly, and the isolation clamping plate 712 is driven to be recovered and clamped through the L-shaped pushing block 716. The provided waterproof strip 713 can prevent water leakage, thereby achieving a sealing effect.

[0036] Working principle: First, the valve core is opened and closed simultaneously by setting the adjustment component 6, and the water source flows into the valve body 1 through the liquid inlet pipe 2. When it needs to be opened and closed, the screw rod 1 612 is driven to rotate by rotating the regulating valve 613. The screw rod 1 612 is threadedly connected with the concave threaded seat 611 and then rises. The screw rod 1 612 drives the rotating rod 615 to rotate and rise. The waterproof sleeve 614 can waterproof the inside of the slot. At the same time, the rotating rod 615 drives the screw rod 2 6111 at the other end to rotate and slowly rises from the fixed threaded sleeve 6112. The fixed threaded sleeve 6112 is fixed to the bottom of the inner wall of the valve body 1. The cooperation of the screw rod 1 612 and the screw 6111 ensures the stability of the valve core 619 and avoids the accuracy being affected by the impact of the water source. The rotating rod 615 retracts the spring 617 through the annular sleeve 616. After the rotating rod 615 rises, it drives the layered sealing sleeve 618 and the valve core 619 to rise. The layered sealing plate 618 and the valve core 619 are respectively connected to the layered sealing plate 618 and the valve core 619. When the locking plate 6114 is separated, the water source inside the clamping frame 6113 is secondary isolated by setting the sealing component 7. At the same time as the rotating rod 615 rises, the layered sealing plate 618 drives the driving inclined block 719 to extend upward and slowly extend to both sides. The driving inclined block 719 is an inclined square block that can cooperate with the layered sealing plate 618. The driving inclined block 719 drives the L-shaped pushing block 716 and the isolation clamping plate 712 to move in conjunction. The L-shaped pushing block 716 slides on the groove plate 718 through the slider 717, and the compression spring 715 is recovered after extending to both sides. The compression spring 715 is stably fixed on both sides of the inner wall of the clamping frame 6113 through the spring fixing seat 714. After the rotating rod 615 is rotated and closed, the compression spring 715 rebounds quickly, and the isolation clamping plate 712 is driven to be recovered and clamped through the L-shaped pushing block 716. The provided waterproof strip 713 can prevent water leakage and reduce water leakage, thereby achieving the effect of precise adjustment and sealing and waterproofing.

[0037] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
