[0030] In order to more clearly understand the above-mentioned objects, features, and advantages of the present utility model, the following further describes the present utility model with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0031] In the following description, many specific details are set forth to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0032] As Figures 1 - 5As shown in the figure, the present utility model provides an adjustable spherical control valve, which includes a housing 1 and a handle 4. A flange 2 is installed on the surface of the housing 1, and a spherical body 3 is installed on the inner wall of the housing 1. A protection device 5 is provided on the surface of the spherical body 3, and an auxiliary device 6 is provided on the surface of the spherical body 3.

[0033] Specifically described below are the specific settings and functions of its protection device 5 and auxiliary device 6.

[0034] As Figures 2 - 4 shown, the protection device 5 includes a plurality of absorption grooves 501. The plurality of absorption grooves 501 are all opened on the arc surface of the spherical body 3. Two diversion holes 502 are communicated with the surface of the absorption groove 501. A collection cavity 503 is communicated with the surface of the two diversion holes 502. A fixing frame 504 is fixedly connected to the surface of the diversion hole 502. A rotating shaft 505 is rotatably connected to the surface of the fixing frame 504. A baffle 506 is fixedly connected to the surface of the rotating shaft 505. A limiting rod 507 is fixedly connected to the surface of the fixing frame 504. A limiting plate 508 is fixedly connected to the surface of the limiting rod 507. The limiting plate 508 abuts against the baffle 506. One side of the baffle 506 is inclined. The absorbed impurities will impact the inclined surface of the baffle 506 on the side close to the absorption groove 501 in the diversion hole 502 under the action of external pressure. At this time, the inclined surface of the baffle 506 on the side close to the absorption groove 501 can facilitate the impurities to push the baffle 506 under the action of pressure. A counterweight 509 is fixedly connected to the surface of the baffle 506. The counterweight 509 abuts against the diversion hole 502. The baffle 506 will drive the counterweight 509 to rotate. At this time, the counterweight 509 can rely on its own gravity to quickly reset the two sides of the baffle 506 under the same pressure. A protective pad 510 is fixedly connected to the surface of the limiting plate 508. The protective pad 510 is a rubber pad. The baffle 506 will abut against the protective pad 510 on the limiting plate 508. At this time, the protective pad 510 made of rubber can protect the contact surface between the limiting plate 508 and the baffle 506.

[0035] As Figure 2 and Figure 5As shown in the figure, the auxiliary device 6 includes a bottom frame 61, the bottom frame 61 is fixedly connected to the sphere body 3, a rotating ring 602 is rotatably connected to the inner wall of the bottom frame 61, a connecting ring 603 is fixedly connected to the surface of the rotating ring 602, a spring 604 is fixedly connected to the surface of the connecting ring 603, the other end of the spring 604 is fixedly connected to a circular plate 605, the circular plate 605 is fixedly connected to the rotary handle 4, a rectangular rod 606 is fixedly connected to the surface of the circular plate 605, a rectangular groove 607 is formed on the surface of the sphere body 3, and the dimensions of the rectangular groove 607 are adapted to those of the rectangular rod 606. A plurality of balls 608 are rotatably connected to the surface of the bottom frame 61, and all the plurality of balls 608 are slidably connected to the rotating ring 602. The rotating ring 602 drives the balls 608 to rotate along the inner wall of the bottom frame 61. At this time, the balls 608 can reduce the friction force between the contact surface of the rotating ring 602 and the bottom frame 61. One end of the rectangular rod 606 is fixedly connected to a sharp cone 609, and the sharp cone 609 is a stainless steel cone. The rectangular rod 606 drives the sharp cone 609 to move in the same direction. At this time, the sharp cone 609 can facilitate the insertion of the rectangular rod 606 into the rectangular groove 607.

[0036] The overall working principle is as follows. When the sealing surfaces of the spherical body 3 and the outer shell 1 are impacted by impurities, scratches or damages may occur. At this time, the absorption groove 501 on the spherical body 3 will absorb the impurities. Then, the absorbed impurities will enter the diversion hole 502 under the action of external pressure. Next, they will impact the inclined surface on the baffle 506 on the side close to the absorption groove 501 in the diversion hole 502. At this time, the inclined surface on the baffle 506 on the side close to the absorption groove 501 can facilitate the impurities to push the baffle 506 under the action of pressure. Then, the baffle 506 will drive the rotating shaft 505 to rotate along the surface of the fixed frame 504. At the same time, the baffle 506 will drive the counterweight 509 to rotate. At this time, the counterweight 509 can rely on its own gravity to quickly reset both sides of the baffle 506 under the same pressure. Then, when the baffle 506 is opened, the impurities will enter the collection chamber 503 through the diversion hole 502 for collection. Then, when a certain amount of impurities are collected in the collection chamber 503, they may flow reversely in the diversion hole 502. At this time, it will push the baffle 506 to rotate reversely. Then, when the baffle 506 rotates to the initial position, it will abut against the limiting plate 508 on the limiting rod 507. At the same time, the baffle 506 will abut against the protective pad 510 on the limiting plate 508. At this time, the protective pad 510 made of rubber can protect the contact surface between the limiting plate 508 and the baffle 506. Then, the limiting plate 508 and the limiting rod 507 can prevent the baffle 506 from rotating excessively. By setting the protection device 5 and using the cooperation among the absorption groove 501, the diversion hole 502, the collection chamber 503, the fixed frame 504, the rotating shaft 505, the baffle 506, the limiting rod 507 and the limiting plate 508, the sealing surfaces of the spherical body 3 and the outer shell 1 can be protected when impacted by impurities, avoiding that in some fluid media containing solid particles, the particles may be embedded between the sealing surfaces, causing wear to the sealing surfaces during the operation of the sealing surfaces between the spherical body 3 and the outer shell 1, resulting in a reduction in the sealing effect and improving the protection effect of the sealing surface of the outer shell 1.

[0037] When it is necessary to open the sphere body 3, first press the handle 4 in the direction close to the outer shell 1. Then the handle 4 will drive the circular plate 605 to move in the same direction. At the same time, the circular plate 605 will drive one end of the spring 604 to move. At this time, the spring 604 itself will generate a reverse elastic force. Then the circular plate 605 will drive the rectangular rod 606 to move into the rectangular groove 607. Then the rectangular rod 606 will drive the tapered cone 609 to move in the same direction. At this time, the tapered cone 609 can facilitate the insertion of the rectangular rod 606 into the rectangular groove 607. When the rectangular rod 606 enters the rectangular groove 607, then start to rotate the handle 4. At this time, the handle 4 will drive the rectangular rod 606 on the circular plate 605 to rotate. At the same time, the rectangular rod 606 will drive the rectangular groove 607 to rotate. Then the rectangular groove 607 will drive the sphere body 3 to rotate and open. When it is not necessary to rotate the sphere body 3, the handle 4 can be released. At this time, the handle 4 will drive the circular plate 605 to move away from the outer shell 1 under the action of the elastic force of the spring 604 itself. At this time, the circular plate 605 will drive the rectangular rod 606 to disengage from the rectangular groove 607. When the handle 4 is accidentally affected by an external force, the handle 4 will drive the spring 604 on the circular plate 605 to rotate. Then the spring 604 will drive the connecting ring 603 to rotate in the same direction. Then the connecting ring 603 will drive the rotating ring 602 to rotate along the bottom frame 61. At the same time, the rotating ring 602 will drive the ball 608 to rotate along the inner wall of the bottom frame 61. At this time, the ball 608 can reduce the friction between the contact surface of the rotating ring 602 and the bottom frame 61. Then the handle 4 will rotate idly and will not drive the sphere body 3 to rotate, ensuring that the working state of the sphere body 3 will not change. By setting the auxiliary device 6 and using the cooperation between the bottom frame 61, the rotating ring 602, the connecting ring 603, the spring 604, the circular plate 605, the rectangular rod 606 and the rectangular groove 607, the sphere body 3 can work and the handle 4 can rotate idly, avoiding the situation that when the handle 4 is accidentally affected by an external force, the handle 4 drives the working sphere body 3 to rotate, which in turn affects the flow rate of the sphere body 3 and improves the stability of the flow rate of the sphere body 3 during operation.
