When the operating environment of the control valve is relatively harsh, the electronic components are easily damaged. For example, in high temperature and high pressure, low temperature and cold working conditions, the surrounding environment can easily cause damage to electronic components. When humans have to enter a high temperature and low temperature environment, it will have a certain impact on the health of the operator.

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] Example 1

[0030] See also Figures 1-8, a self-regulating thermal valve includes a valve body 1, with an inlet 7 and an outlet 8 respectively provided on the left and right sides of the valve body 1; a valve disc 6; a self-regulating component 3, which is used to automatically regulate the flow rate of the valve body 1 according to the fluid flow pressure of the valve body 1; the self-regulating component 3 includes a coil spring 301, one end of the coil spring 301 is connected to a reel 302, and the other end of the coil spring 301 is connected to a toothed disk 303, the toothed disk 303 is connected to the valve disc 6 through a connecting piece, a sliding block 601 is provided on the valve disc 6, a pressure water tank 101 is provided on the inner wall of the valve body 1, and a filter screen 604 is provided on the valve disc 6. After the fluid enters the position of the inlet 7, the pressure of the fluid enters the interior of the pressure water tank 101, and then drives the valve disc 6 to rotate by pushing the sliding block 601 to rotate, so that the filter screen 604 faces the inlet 7. The fluid enters the interior of the valve body 1 from the position of the inlet 7. At this time, because the sealing sleeve 201 seals the position of the inlet 7, the fluid will enter the interior of the pressure tank 101. When the fluid pressure reaches a certain pressure value, it will push the sliding block 601 to rotate inside the pressure tank 101, thereby driving the valve flap 6 to rotate, and then controlling the opening position on the valve flap 6 to face the inlet 7. Therefore, at this time, the fluid will enter the interior of the valve body 1 from the opening position and be discharged from the position of the outlet 8. Therefore, when the fluid flows, it indirectly overcomes the elastic force of the coil spring 301 to realize the opening of the fluid channel. Although after the fluid channel is opened, the fluid will flow out through some channels and there will be a certain degree of pressure relief process, but the fluid pressure will still exist. When the fluid pressure stabilizes at a certain value, the constant force exerted on the coil spring 301 will tend to a stable state, so that the internal flow channel is in a stable state.

[0031] In this embodiment, two filters 102 are fixedly connected to the pressure water tank 101. The surfaces of the filters 102 abut against the sliding block 601. The bottom of the valve disc 6 is connected to an adjusting rod 4, which is rotatably connected to the valve body 1. The interior of the sliding block 601 is slidably connected to a sliding post 602, which is fixed to the interior of the valve disc 6. A contraction spring 603 is sleeved on the surface of the sliding post 602. The purpose of providing the adjusting rod 4 is to adjust the flow direction according to different fluids. If the valve body is required to be in a flowing state initially, the adjusting rod 4 needs to be controlled to rotate a certain angle during the initial installation of the valve body 1, thereby driving the valve disc 6 to rotate the same angle. Initially, the filter screen 604 is facing the direction of the inlet 7, so that the valve body 1 is in the open state. The fluid will then enter through the position of the filter screen 604 and be discharged from the position of the outlet 8. Therefore, the operator can control the "initial flow state" of the valve body 1 according to the actual pipeline flow.

[0032] Furthermore, the connecting piece includes a slot 605, which is provided at the top of the valve disc 6. The bottom teeth of the toothed disc 303 are engaged with the inside of the slot 605. A spring plate is provided at the bottom of the coil spring 301. A force spring 307 is provided between the spring plate and the toothed disc 303. The purpose of the force spring 307 is to achieve rotation by utilizing the toothed state when the valve disc 6 is rotated alone, thereby regulating whether the valve body 1 is connected or closed in the initial stage of flow. Because it is in the toothed state, when regulating the valve disc 6 alone, it will be lifted by the teeth, controlling the toothed disc 303 to move upward, thereby squeezing and giving way to the force spring 307.

[0033] Furthermore, the self-regulating component 3 also includes a pressure regulating component 5, which is used to regulate the torque of the coil spring 301; the pressure regulating component 5 includes an adjusting shaft 501, which is rotatably connected to the valve body 1, and the adjusting shaft 501 is connected to a wheel 505, and the wheel 505 is rotatably connected to a ratchet 503, and the ratchet 503 is connected to an extrusion spring 504, one end of the extrusion spring 504 is connected to the wheel 505, and the surface of the ratchet 503 is clamped with a ratchet ring 306. Because the pressure of the flow channel during installation of the valve body 1 is different, a setting is provided to adjust the initial pressure of the coil spring 301 to adapt the fluid pressure of the valve body 1. At this time, at the initial stage of installation, the rotation of the adjusting shaft 501 is controlled by a wrench or tool, thereby driving the rotation of the wheel 505. The rotation of the adjusting shaft 501 will synchronously drive the rotation of the reel 302, and the rotation of the reel 302 will synchronously drive the coil spring 301 to contract. When it is rotated to a certain angle, the adjusting shaft 501 is released and the ratchet ring 306 is engaged through the multiple ratchet clips 503 on the wheel 505. Therefore, one end of the coil spring 301 will contract and be fixed. Later, when the fluid pressure pushes the sliding block 601 to rotate, the work required will increase, and the operator can adjust the tightness of the coil spring 301 according to the actual fluid pressure, thereby improving the overall applicability of the valve body 1.

[0034] In addition, the bottom of the ratchet ring 306 is connected to a force-bearing spring 307, and the bottom of the force-bearing spring 307 is connected to a positioning piece 304, which is fixed inside the valve body 1. The top of the ratchet ring 306 is connected to a pressure frame 502 via multiple connecting rods. When the contraction force of the coil spring 301 needs to be released, the operator needs to press the pressure frame 502 downward through the connection of multiple connecting rods to drive the ratchet ring 306 downward, thereby compressing the yield spring 305, thereby controlling the ratchet ring 306 to move downward and disengage the multiple ratchet clips 503. At this time, the adjustment shaft 501 is released by the elastic force of the coil spring 301, which will drive the synchronous automatic rotation of the coil shaft 302 and the adjustment shaft 501, thereby releasing the elastic force of the coil spring 301, making it convenient for the operator to reset and control the elastic force of the coil spring 301 of the valve body 1.

[0035] In addition, there are multiple ratchet latches 503, and the multiple ratchet latches 503 are arranged in a circular array with the center of the wheel 505 as the center. The wheel 505 and the ratchet latches 503 are both located inside the valve body 1. The multiple ratchet latches 503 will provide a multiple-position locking effect, making the entire wheel 505 more stable during the rotation control stage.

[0036] Example 2

[0037] A sealing structure includes a sealing assembly 2, which includes a circular sealing rubber sleeve 201. The sealing rubber sleeve 201 is disposed on a valve disc 6, and its height is greater than the diameter of an inlet 7. The valve disc 6 is rotatably connected to two rotating posts 203, around which the sealing rubber sleeve 201 is wound. The valve disc 6 is fixedly connected to an arcuate patch 202, which abuts against the sealing rubber sleeve 201. The patch 202 ensures that the outermost sealing rubber sleeve 201 is in contact with the outermost sealing rubber sleeve 201, thereby preventing sealing failure caused by deformation of the sealing rubber sleeve 201 due to fluid compression. The arc-shaped double-layer sealing rubber sleeve 201 is used to perform contact sealing on the position of the inlet 7. When the fluid pressure decreases, the contraction of the coil spring 301 will synchronously drive the valve flap 6 to reset and rotate, and drive the sealing rubber sleeve 201 on the valve flap 6 to be repositioned to the position facing the inlet 7. A groove 103 is provided inside the valve body 1, and a circular array of teeth is provided inside the groove 103. A small gear 204 is connected to the bottom of the rotating column 203, and the small gear 204 meshes with the teeth inside the groove 103. When the valve disc 6 rotates, it will drive the sealing rubber sleeve 201 to rotate, and will simultaneously drive the small gear 204 on the rotating column 203 to rotate, and the small gear 204 will engage and rotate with the internal teeth of the groove 103, thereby driving the rotating column 203 to rotate. Therefore, at this time, the sealing rubber sleeve 201 in the circular state will realize the transmission and rotation following the valve disc 6. At this time, the rolling method is used to directly avoid the large contact friction between the sealing rubber sleeve 201 and the valve body 1 affecting the rotation and giving way of the valve disc 6, so the movement and displacement of the entire valve disc 6 are smoother, and the sealing effect will not be reduced.

[0038] Working principle: First, when the valve body 1 is in operation as a whole, the fluid enters the interior of the valve body 1 from the position of the inlet 7. At this time, because the sealing rubber sleeve 201 seals the position of the inlet 7, the fluid will enter the interior of the pressure tank 101. When the fluid pressure reaches a certain pressure value, it will push the sliding block 601 to rotate inside the pressure tank 101, thereby driving the valve disc 6 to rotate. When the valve disc 6 rotates, it will control the rotation of the sealing rubber sleeve 201, causing it to shift from the position of the inlet 7. After that, the filter screen 604 on the valve disc 6 will gradually rotate to the position of the inlet 7, and the fluid will pass through the filter screen 604 and enter the interior of the valve disc 6. It then moves downward from the internal space and is discharged from the position of the outlet 8, ultimately realizing the inflow and outflow control of the fluid. When the valve disc 6 rotates, it will synchronously drive the toothed disc 303 to rotate through the upper slot 605, and the toothed disc 303 will contract in connection with the coil spring 301. Therefore, when the fluid flows, it indirectly overcomes the elastic force of the coil spring 301 to realize the opening of the fluid channel. Although after the fluid channel is opened, the fluid will flow out through some channels and there will be a certain degree of pressure relief process, but the pressure of the fluid will still exist. When the fluid pressure stabilizes at a value, the constant force exerted on the coil spring 301 will tend to a stable state. The entire device is provided with an adjusting rod 4. The purpose of the adjusting rod 4 is to cope with different fluids and adjust the flow direction. If the initial state of the valve body needs to be a flow state, it is necessary to control the adjusting rod 4 to rotate a certain angle at the initial stage of installing the valve body 1, and then drive the valve disc 6 to rotate the same angle, so that the filter screen 604 is facing the direction of the inlet 7 in the initial stage, so the valve body 1 is in an open state at this time, and then the fluid will enter from the position of the filter screen 604, and then be discharged from the position of the outlet 8. When the fluid pressure is greater, when the outlet 8 is unable to discharge in time, part of the fluid pressure will still enter from the position of the pressure tank 101, and then drive the valve flap 6 to rotate through the push of the fluid, and then control the rotation of the valve flap 6, rotate the sealing rubber sleeve 201 to a certain angle, and then rotate slowly to reduce the position of the inlet 7. Therefore, the greater the fluid pressure at this time, the displacement of the inlet 7 will be automatically controlled, but the flow of the valve body 1 will not be closed, because the fluid is equivalent to two flow channels at this time, one is in the position of the pressure tank 101, and the other is the flow channel of the valve body 1, and the fluid is a delivery pressure that always exists, so the pressure tank 101 will always accumulate fluid pressure.The entire device is also provided with a pressure regulating assembly 5, which is mainly used to regulate the initial pressure of the coil spring 301. Because the pressure of the flow channel where the valve body 1 is installed is different, it is provided with a device that can regulate the initial pressure of the coil spring 301 to adapt the fluid pressure of the valve body 1. At this time, at the initial stage of installation, the rotation of the adjusting shaft 501 is controlled by a wrench or tool, thereby driving the rotation of the wheel 505. The rotation of the adjusting shaft 501 will synchronously drive the reel 302 to rotate, and when the reel 302 rotates, it will synchronously drive the coil spring 301 to contract. When it rotates to a certain angle, When the adjusting shaft 501 is loosened, the ratchet ring 306 will be engaged through the multiple ratchets 503 on the wheel 505, so one end of the coil spring 301 will shrink and be fixed. Then, when the fluid pressure pushes the sliding block 601 to rotate, the work required will increase, and the operator can adjust the tightness of the coil spring 301 according to the actual fluid pressure. The looser the coil spring 301, the smaller the pressure pushed by the fluid, which can directly drive the movement of the valve disc 6. The tighter the coil spring 301, the greater the pressure required by the fluid to push the valve disc 6 to rotate, which is suitable for pipeline control with different flow channel pressures. When the coil spring 301 transmits the rotational elastic force to the toothed disc 303, the slot 605 on the valve flap 6 will be connected to the reverse teeth at the bottom of the toothed disc 303, driving the rotation of the toothed disc 303, and then driving the rotation and contraction of the coil spring 301, and the sliding block 601 is in contact with the filter disc 102, thereby limiting the initial position of the valve flap 6. Because the position of the filter disc 102 is fixed, when the coil spring 301 transmits the reverse torsional force to the toothed disc 303, the toothed disc 303 will provide a torsional force to the valve flap 6, so that the sliding block 601 on the valve flap 6 is in contact with the filter disc 102, thereby fixing the initial position. The purpose of providing two filter discs 102 is to regulate the flow of the valve body in the initial stage. When the valve body 1 is required to be in a flow state in the initial stage, the valve disc 6 needs to be manually controlled to rotate, and the sliding block 601 needs to be controlled to rotate onto the other filter disc 102 so that the filter screen 604 is facing the inlet 7. At this time, the sliding block 601 is abutted by the other filter disc 102, which will directly limit the initial position of the valve disc 6 and keep it fixed. When the contraction force of the coil spring 301 needs to be released, the operator needs to press the pressing frame 502 downward to drive the ratchet ring 306 downward through the connection of multiple connecting rods, thereby compressing the yield spring 305, thereby controlling the ratchet ring 306 to move downward and disengage the multiple ratchet clips 503. At this time, the elastic force of the coil spring 301 is released on the adjustment shaft 501, which will drive the synchronous automatic rotation of the coil shaft 302 and the adjustment shaft 501, thereby releasing the elastic force of the coil spring 301. Afterwards, the pressure frame 502 is released and stretched by the yield spring 305 , and the ratchet ring 306 is re-engaged with the ratchet 503 , thereby facilitating the operator to reset and regulate the elastic force of the coil spring 301 of the valve body 1 .

[0039] In addition, the entire device is provided with a sealing component 2 with a special structure, which uses an arc-shaped double-layer sealing sleeve 201 to contact and seal the position of the inlet 7. When the fluid pressure decreases, the contraction of the coil spring 301 will synchronously drive the valve disc 6 to reset and rotate, and drive the sealing sleeve 201 on the valve disc 6 to be repositioned to the position facing the inlet 7. In order to avoid the large contact friction between the sealing sleeve 201 and the valve body 1, which makes it difficult for the valve disc 6 to rotate, a small gear 204 is provided. When the valve disc 6 rotates, it will drive the sealing sleeve 201 to rotate and synchronously drive the small gear 204 on the rotating column 203 to rotate. The small gear 204 will mesh with the internal teeth of the groove 103 to rotate, and then drive the rotating column 203 to rotate. At this time, the sealing sleeve 201 in the circular state will realize the transmission and rotation following the valve disc 6. At this time, the rolling method is used to directly avoid the large contact friction between the sealing sleeve 201 and the valve body 1 affecting the rotation and giving way of the valve disc 6.
