A highly sealed valve and its pipeline system

Abstract

The present invention provides a highly sealed valve and its pipeline system, which relates to the field of ball valves. The highly sealed valve includes a valve body, and the valve body includes a valve housing. A spherical valve core is rotatably connected inside the valve housing. Both sides of the top of the trunnion above the spherical valve core are fixedly connected with strong magnets. The top of the valve housing is fixedly connected with an outer shell. A worm gear is rotatably connected inside the outer shell. Both sides of the bottom of the worm gear are fixedly connected with electromagnets. The magnetism generated after the electromagnets are energized is different from the magnetism of the strong magnets. Through the mutual attraction between the electromagnets and the strong magnets, the spherical valve core is driven to rotate inside the valve housing to realize the opening and closing of the valve. Since the valve abandons the traditional valve stem design, it avoids the need for the valve stem to penetrate the valve body, thereby preventing the decrease in the sealing performance of the valve after long-term use and completely eliminating the possibility of internal medium leakage, resulting in higher sealing performance.

Description

Technical Field

[0001] The present invention relates to the technical field of ball valves, and specifically to a highly sealed valve and its pipeline system. Background Art

[0002] In the prior art, most of the spherical valve cores of ball valves are driven by a valve stem and rotate around the axis of the ball valve to achieve the opening and closing of the valve. Since the rotation of the valve stem requires a driving force, the valve stem needs to penetrate the valve body and extend to the outside, so there must be a gap between the valve stem and the valve body.

[0003] Due to the fact that the above gap cannot be completely filled, after long-term use of the existing ball valves, leakage will inevitably occur at this gap, which seriously affects the sealing performance of the valve and poses potential hazards for subsequent use. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the present invention provides a highly sealed valve and its pipeline system, which solves the problem that the gap between the valve stem and the valve body in the existing ball valves cannot be completely sealed.

[0005] To achieve the above objectives, the present invention is realized through the following technical solutions: A highly sealed valve, including a valve body, the valve body includes a valve housing, a spherical valve core is rotatably connected inside the valve housing, both sides of the top of the trunnion above the spherical valve core are fixedly connected with strong magnets, the top of the valve housing is fixedly connected with an outer housing, a worm gear is rotatably connected inside the outer housing, both sides of the bottom of the worm gear are fixedly connected with electromagnets, the magnetism generated after the electromagnets are energized is opposite to the magnetism of the strong magnets, a worm is rotatably connected to one side inside the outer housing, and the worm is meshed with the worm gear;

[0006] One side of the outer housing is fixedly connected with a reduction gearbox, the outside of the reduction gearbox is fixedly connected with a motor, the output end of the reduction gearbox is connected to one end of the worm, the input end of the reduction gearbox is connected to the driving end of the motor, the top of the outer housing is fixedly connected with a controller, the controller has a wireless communication function and the controller is signal-connected to the motor.

[0007] Preferably, one side of the valve housing is fixedly connected with a first pipeline, the outside of the end of the first pipeline away from the valve housing is fixedly connected with a first sleeve, and the outside of the first sleeve is fixedly connected with a first snap ring;

[0008] The other side of the valve housing is fixedly connected with a second pipeline, the outer diameter of the second pipeline is equal to the inner diameter of the first sleeve, and a plurality of second snap rings are fixedly connected at equal intervals on the outside of the end of the second pipeline away from the valve housing.

[0009] Preferably, a pipeline system is a pipeline system based on the high-sealing valve described above, including a valve body and a pipeline component. The valve body and the pipeline component can be adaptively connected. The pipeline component includes a pipeline section. One end of the pipeline section is fixedly connected with a second sleeve on the outside, and a third snap ring is fixedly connected to the outside of the second sleeve. The inner diameter of the third snap ring is equal to the outer diameters of the pipeline section, the first pipeline, and the second pipeline. A plurality of fourth snap rings are fixedly connected to the outside of the other end of the pipeline section at equal intervals. The number of the fourth snap rings is equal to the number of the second snap rings;

[0010] The inner and outer diameters of the pipeline section are respectively equal to the inner and outer diameters of the first pipeline and the second pipeline. The outer diameters of the fourth snap rings are respectively equal to the outer diameters of the third snap ring, the first snap ring, and the second snap ring.

[0011] Preferably, the pipeline component further includes a semi-nesting and a sealing rubber ring. The sealing rubber ring can be sleeved on the outside of the second sleeve or the first sleeve. The inner diameter of the sealing rubber ring is respectively consistent with the outer diameters of the second sleeve and the first sleeve. The outer diameters of the sealing rubber ring are respectively equal to the outer diameters of the third snap ring, the fourth snap ring, the first snap ring, and the second snap ring;

[0012] The two semi-nestings can be connected into a complete ring buckle by bolts. The inside of the ring buckle can be adapted to the outside of the joint of the combination of the pipeline section, the second sleeve, the third snap ring, the sealing rubber ring, the second pipeline, and the second snap ring. The inside of the ring buckle can be adapted to the outside of the joint of the combination of the first pipeline, the first sleeve, the first snap ring, the sealing rubber ring, the pipeline section, and the fourth snap ring. The inside of the ring buckle can be adapted to the outside of the joint of the combination of the pipeline section, the second sleeve, the third snap ring, the sealing rubber ring, and the fourth snap ring.

[0013] Working principle: Since the magnetism generated after the electromagnet is powered on is different from that of the strong magnet, when the controller receives a remote control signal, it can command the motor to act, and then drive the worm gear to rotate through the reduction gearbox and the worm. Then, through the mutual attraction between the electromagnet and the strong magnet, the spherical valve core is driven to rotate inside the valve housing to achieve the opening and closing of the valve. Since the valve abandons the traditional valve stem design, it avoids the need for the valve stem to penetrate the valve body, which may lead to a decrease in the valve's sealing performance after long-term use, completely eliminating the possibility of internal medium leakage and having a higher sealing performance. In addition, in this pipeline system, two semi-nested parts can be connected into a complete loop through bolts. The inside of the loop can be adapted to the outside of the connection of the combination of the pipeline section, the second sleeve, the third snap ring, the sealing rubber ring, the second pipeline, and the second snap ring, or the outside of the connection of the combination of the first pipeline, the sealing rubber ring, the pipeline section, and the fourth snap ring, or the outside of the connection of the combination of the pipeline section, the second sleeve, the third snap ring, the sealing rubber ring, and the fourth snap ring. Thus, the modular design idea makes the assembly of this pipeline system more flexible and convenient. At the same time, through the above-mentioned nested adaptation, the connection structure of this pipeline system avoids the situation of low sealing performance caused by connecting through flange plates in the past.

[0014] The present invention provides a highly sealed valve and its pipeline system. It has the following beneficial effects:

[0015] 1. In the present invention, since the magnetism generated after the electromagnet is powered on is different from that of the strong magnet, when the controller receives a remote control signal, it can command the motor to drive the electromagnet at the bottom of the worm gear to rotate. Then, through the mutual attraction between the electromagnet and the strong magnet, the spherical valve core is driven to rotate inside the valve housing to achieve the opening and closing of the valve. Since the valve abandons the traditional valve stem design, it avoids the need for the valve stem to penetrate the valve body, which may lead to a decrease in the valve's sealing performance after long-term use, completely eliminating the possibility of internal medium leakage and having a higher sealing performance.

[0016] 2. Through the modular design idea of structures such as semi-nested parts, pipeline sections, and sealing rubber rings, the assembly of this pipeline system is made more flexible and convenient. At the same time, through the above-mentioned nested adaptation, the connection structure of this pipeline system avoids the situation of low sealing performance caused by connecting through flange plates in the past.

Detailed implementation manners

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0026] Embodiment:

[0027] As Figures 1-7 shown, the embodiment of the present invention provides a highly sealed valve, including a valve body 1, and also provides a pipeline system including a valve body 1 and a pipeline assembly 2.

[0028] Specifically, the valve body 1 includes a valve housing 101, a spherical valve core 102 is rotatably connected inside the valve housing 101, both sides of the top of the trunnion above the spherical valve core 102 are fixedly connected with strong magnets 103, the top of the valve housing 101 is fixedly connected with an outer housing 107, a worm gear 104 is rotatably connected inside the outer housing 107, both sides of the bottom of the worm gear 104 are fixedly connected with electromagnets 105, the magnetism generated after the electromagnets 105 are energized is opposite to the magnetism of the strong magnets 103, and a worm 106 is rotatably connected to one side inside the outer housing 107, and the worm 106 is meshed with the worm gear 104;

[0029] Further, a reduction gearbox 108 is fixedly connected to one side of the outer shell 107, an electric motor 109 is fixedly connected to the outside of the reduction gearbox 108, the output end of the reduction gearbox 108 is connected to one end of the worm 106, the input end of the reduction gearbox 108 is connected to the driving end of the electric motor 109, a controller 110 is fixedly connected to the top of the outer shell 107, the controller 110 has a wireless communication function and the controller 110 is signal-connected to the electric motor 109.

[0030] Since the magnetism generated after the electromagnet 105 is energized is different from that of the strong magnet 103, when the controller 110 receives a remote control signal, it can instruct the electric motor 109 to act, and then drive the worm gear 104 to rotate through the reduction gearbox 108 and the worm 106. Furthermore, through the mutual attraction between the electromagnet 105 and the strong magnet 103, the spherical valve core 102 is driven to rotate inside the valve housing 101 to realize the opening and closing of the valve. Since the valve abandons the traditional valve stem design, it avoids the valve stem from penetrating the valve body, which may lead to a decrease in the valve sealing performance after long-term use, completely eliminating the possibility of internal medium leakage and having a higher sealing performance.

[0031] Further, a first pipeline 111 is fixedly connected to one side of the valve housing 101, a first sleeve 112 is fixedly connected to the outside of the end of the first pipeline 111 away from the valve housing 101, a first snap ring 113 is fixedly connected to the outside of the first sleeve 112, a second pipeline 114 is fixedly connected to the other side of the valve housing 101, the outer diameter of the second pipeline 114 is equal to the inner diameter of the first sleeve 112, and a plurality of second snap rings 115 are fixedly connected to the outside of the end of the second pipeline 114 away from the valve housing 101 at equal intervals.

[0032] On the other hand, a pipeline system based on the above high-sealing valve provided in this embodiment includes a valve body 1 and a pipeline assembly 2. The valve body 1 and the pipeline assembly 2 can be adaptively connected. The pipeline assembly 2 includes a pipeline section 201. A second sleeve 202 is fixedly connected to the outside of one end of the pipeline section 201, a third snap ring 203 is fixedly connected to the outside of the second sleeve 202, the inner diameter of the third snap ring 203 is equal to the outer diameters of the pipeline section 201, the first pipeline 111, and the second pipeline 114. A plurality of fourth snap rings 204 are fixedly connected to the outside of the other end of the pipeline section 201 at equal intervals. The number of the fourth snap rings 204 is equal to the number of the second snap rings 115. The inner and outer diameters of the pipeline section 201 are respectively equal to the inner and outer diameters of the first pipeline 111 and the second pipeline 114. The outer diameters of the fourth snap rings 204 are respectively equal to the outer diameters of the third snap ring 203, the first snap ring 113, and the second snap ring 115.

[0033] Furthermore, the pipe component 2 further includes a semi-nesting 205 and a sealing rubber ring 206. The sealing rubber ring 206 can be sleeved outside the second sleeve 202 or the first sleeve 112. The inner diameter of the sealing rubber ring 206 is respectively consistent with the outer diameters of the second sleeve 202 and the first sleeve 112. The outer diameter of the sealing rubber ring 206 is respectively equal to the outer diameters of the third snap ring 203, the fourth snap ring 204, the first snap ring 113, and the second snap ring 115. The two semi-nestings 205 can be bolted together to form a complete ring buckle. The inside of the ring buckle can be adapted to the outside of the joint of the combination of the pipe section 201, the second sleeve 202, the third snap ring 203, the sealing rubber ring 206, the second pipe 114, and the second snap ring 115. The inside of the ring buckle can be adapted to the outside of the joint of the combination of the first pipe 111, the first sleeve 112, the first snap ring 113, the sealing rubber ring 206, the pipe section 201, and the fourth snap ring 204. The inside of the ring buckle can be adapted to the outside of the joint of the combination of the pipe section 201, the second sleeve 202, the third snap ring 203, the sealing rubber ring 206, and the fourth snap ring 204.

[0034] In this pipe system, the two semi-nestings 205 can be bolted together to form a complete ring buckle. The inside of the ring buckle can be adapted to the outside of the joint of the combination of the pipe section 201, the second sleeve 202, the third snap ring 203, the sealing rubber ring 206, the second pipe 114, and the second snap ring 115, or to the outside of the joint of the combination of the first pipe 111, the sealing rubber ring 206, the pipe section 201, and the fourth snap ring 204, or to the outside of the joint of the combination of the pipe section 201, the second sleeve 202, the third snap ring 203, the sealing rubber ring 206, and the fourth snap ring 204. Therefore, through the above modular design concept, the assembly of this pipe system is more flexible and convenient. At the same time, through the above nesting and adaptation, the connection structure of this pipe system avoids the situation of low sealing performance caused by connecting through flange plates in the past.
