Description

Technical Field

[0001] The present invention relates to the technical field of angle regulating valves, in particular to an anti-clogging angle regulating valve for a horizontal flow channel. Background Art

[0002] Angle control valve is an executive unit instrument widely used in industrial automation process control. It is generally composed of a straight-stroke electric actuator and an angle valve. It adopts a single-seat plunger-shaped valve core and a top-guided structure. The flow path in the valve body is simple, there is no dead angle, and it is easy to self-clean and clean. It is mainly powered by a single-phase AC power supply or compressed air. After receiving the control signal, the actuator generates axial thrust to drive the control valve to control the opening of the valve and realize continuous adjustment of process parameters such as pressure, temperature, flow, and liquid level. Therefore, it is widely used in automatic control systems of industrial sectors such as electricity, metallurgy, petroleum, chemical industry, light industry and food. When the angle control valve is used to transport sewage containing suspended particle media, noise will be generated due to the impact of water on the valve body, and the noise caused by the impact of water flow cannot be reduced. When in use, the noise will affect the auditory system of the staff, and its practicality is poor. In order to overcome the above-mentioned defects, prior art 1 (application number CN202220213651.9, Chinese patent application date 2022-01-26) is a low-noise and scour-resistant angle regulating valve. Compared with the prior art, it has a simple structure and is easy to process. Through the spring buffer structure, the impact of the fluid medium on the valve core is reduced, and the scour resistance of the valve core is improved. There is also prior art 2 (application number CN202321628341.4, Chinese patent application date 2023-06-26) is a low-noise sleeve pneumatic regulating valve. Water flows in from the water inlet end and flows out from the water outlet end. The fluid is reduced in noise by the water inlet noise reduction component inside the water inlet end; the fluid is reduced in noise by the water outlet noise reduction component inside the water outlet end. The purpose of reducing the noise of the pneumatic control valve body when it is working is achieved to avoid affecting the surrounding environment, and the existing technology 3 (application number CN202222439842.X, Chinese patent application date 2022-09-15) is a silent electric control valve with a noise reduction structure. When the water retaining body in the valve body moves, the water flows from the water retaining body position to the silencer pipe, and will hit the soft layer to reduce the impact noise of the water flow. Furthermore, by providing a first retaining ring, a second retaining ring, a silencer cotton layer, a silencer arc plate, a connecting plate, a connecting column and a limit arc plate, the silencer cotton layer and the silencer arc plate can better block the noise generated by the electric control valve, so that the electric control valve has a better silent effect.

[0003] Although the existing technology can achieve noise reduction processing for the fluid transported by the regulating valve to reduce the impact on the hearing system of the staff, when the regulating valve transports sewage containing suspended particle media, it is extremely easy for sewage impurities to accumulate, become stuck, and have poor circulation inside the valve body, which fails to meet the technical requirements for regulating and controlling process parameters such as flow and pressure, thereby affecting the subsequent transportation efficiency of the angle regulating valve and having poor practicality. Therefore, a horizontal flow channel anti-clogging angle regulating valve is proposed to solve the above-mentioned problems. Summary of the Invention

[0004] The purpose of the present invention is to provide an anti-clogging angle regulating valve for a horizontal flow channel to solve the problem raised in the above background technology that the valve body in the current market is extremely prone to accumulation of sewage impurities, blockage, poor circulation and other faults, which cannot meet the technical requirements for regulating and controlling process parameters such as flow rate and pressure, thereby affecting the later delivery efficiency of the angle regulating valve and having poor practicality.

[0006] Preferably, a filter plate is provided below the valve core, and the filter plate is inclined, and a discharge pipe is provided below the filter plate, and the bottom of the valve body is in an arc shape.

[0007] Preferably, the positioning frame is hollow, and the diameter of the water wheel is smaller than the diameter of the valve body.

[0008] Preferably, a second rotating shaft is rotatably installed inside the discharge pipe, and a circle of water receiving plates is positioned and installed on the outer side surface of the second rotating shaft, wherein the circle of water receiving plates are of equal angles, and each water receiving plate is in an arc shape.

[0009] Preferably, a first magnet is installed on the outer surface of a circle of the water receiving plate, a cleaning rack is slidably installed inside the discharge pipe, and a second magnet is provided above the cleaning rack.

[0010] Preferably, there is a first magnet above the second magnet, and the first magnet and the second magnet have the same magnetic poles.

[0011] Preferably, the interior of the discharge pipe is connected to one end of two second return springs, and the two second return springs have the same structure, and the other ends of the two second return springs are connected to a cleaning rack.

[0012] Preferably, a limit block is slidably installed inside the connecting flange through two first return springs, and the two limit blocks on the side away from the connecting flange are in an arc shape, and the outer ends of the two limit blocks extend through the interior of the connecting disk, the two connecting disks are symmetrically arranged about the vertical center line of the valve body, and the outer side surfaces of the two connecting disks are sealed with pipelines, and the outer ends of the two limit blocks are in an arc shape.

[0013] Preferably, two pressing rods are slidably installed inside the connecting plate through a tension spring, and the outer side surfaces of the two pressing rods are connected to one end of the tension spring, and the other end of the two tension springs is connected to the connecting plate, and the inner ends of the two pressing rods are arc-shaped.

[0014] Preferably, the interior of the connecting disk is connected to a circle of force storage springs, and a circle of force storage springs away from the connecting disk is connected to a top plate, wherein the top plate is slidably installed inside the connecting disk, a sealing airbag is provided on the side of the top plate away from the connecting disk, and the outer side surface of the sealing airbag is fitted with a connecting flange.

[0015] Compared with the prior art, the present invention has the following beneficial effects: (1) A filter plate is provided. A metal filter plate is installed in the inner cavity of the valve body. The fluid impurities in the transported sewage can be filtered and screened by the filter plate. The filtered and screened fluid impurities can then be discharged from the bottom outside of the valve body through the discharge pipe, thereby realizing the material extraction and processing of sewage impurities, which is more practical.

[0016] (2) A water wheel is provided. When the sewage valve body is conveying sewage, the potential energy of the sewage flow will drive the first rotating shaft connected to the water wheel to rotate. At this time, the eccentric wheel installed at the right end of the first rotating shaft will drive the eccentric wheel to rotate, collide and vibrate the arc block set under the mounting plate. The vibration force generated at this time can filter the filter plate, thereby avoiding the phenomenon that sewage impurities stick to the surface of the filter plate and affect the blockage of sewage in the later stage, thereby improving the conveying efficiency of the angle regulating valve.

[0017] (3) A water receiving plate is provided.

Not only can the cleaning frame be used to clean and scrape the impurities stuck on the inner wall of the discharge pipe, but the vibration force of the cleaning frame after reset can also be used to vibrate and hit the discharge pipe, so as to avoid impurities sticking to the inner wall of the discharge pipe and affecting the subsequent discharge use, thereby improving the convenience of the angle regulating valve in discharging sewage impurities.

[0018] (4) A limit block is provided, and a limit block with an arc-shaped outer end is slidably installed inside the connecting flange through two first return springs. When it is necessary to seal the external pipe, it is only necessary to press the connecting plate to retract and move. At this time, the two arc-shaped limit blocks will retract and move due to the squeezing of the connecting plate, and then the two limit blocks can be automatically ejected into the connecting plate by the two first return springs, so that the position of the connected pipeline can be positioned and fixed, avoiding the pipeline from loosening and falling off due to vibration and collision during later use.

[0019] (5) Furthermore, when the connecting plate is installed on the outside of the connecting flange, the top plate provided inside the connecting plate will shrink and move due to the squeezing of the connecting flange, and then a circle of force storage spring will be squeezed at the same time to store force, so that the auxiliary pipeline can be quickly disassembled and replaced later. During the installation process of the connecting flange and the connecting plate, the sealing airbag provided on the outside of the top plate will seal the connection between the connecting flange and the connecting plate by squeezing, thereby avoiding leakage at the connection between the connecting flange and the connecting plate after long-term use, and achieving a better sealing effect.

DETAILED DESCRIPTION

[0022] 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.

[0023] The present invention provides the following technical solution, an anti-clogging angle regulating valve for a horizontal flow channel: Embodiment 1, in order to solve the problem that the existing valve body 1 is extremely prone to sewage impurity accumulation, obstruction, poor flow and other faults, which cannot meet the technical requirements of flow rate, pressure and other process parameters adjustment and control, thereby affecting the delivery efficiency of the later angle regulating valve and having poor practicality, discloses: a valve body 1, and a filter plate 20 arranged inside the valve body 1 for filtering and screening, a positioning frame 21 is installed inside the valve body 1 for positioning, and a first rotating shaft 18 is rotatably installed inside the positioning frame 21, and a water wheel 19 is provided at the left end of the first rotating shaft 18, and a discharge pipe 7 is sealed and installed at the bottom of the valve body 1. A valve seat 3 is provided above the valve body 1, and a membrane cover 5 is provided on the top of the valve seat 3. A valve stem 4 is provided inside the valve seat 3 through a driving mechanism, and the bottom of the valve stem 4 extends through the valve body 1. At the same time, a valve core 17 is connected to the bottom end of the valve stem 4. A pressure gauge 6 for detecting the pressure coefficient is also provided above the valve seat 3. An eccentric wheel 25 is connected and installed at the right end of the first rotating shaft 18, and a collision block 24 is installed on the outer side of the eccentric wheel 25, and an arc block 23 is correspondingly provided above the collision block 24. The arc block 23 is installed below the mounting plate 22, and the mounting plate 22 is installed inside the valve body 1.

[0024] There is a filter plate 20 below the valve core 17, and the filter plate 20 is inclined, and there is a discharge pipe 7 below the filter plate 20. The bottom of the valve body 1 is in an arc shape, the positioning frame 21 is hollow, and the diameter of the water wheel 19 is smaller than the diameter of the valve body 1.

[0025] like Figures 1-9 As shown, when the angle regulating valve is transporting sewage, the filter plate 20 arranged inside the valve body 1 filters and screens the fluid impurities in the transported sewage, and then the filtered and screened fluid impurities can be discharged from the bottom outside of the valve body 1 through the discharge pipe 7, so that the sewage impurities can be taken out for processing. The potential energy of the sewage flow will drive the first rotating shaft 18 connected to the inner end of the water wheel 19 to rotate. At this time, the rotating first rotating shaft 18 will simultaneously drive the collision block 24 provided at the outer end of the eccentric wheel 25 to squeeze and collide with the arc block 23 provided under the mounting plate 22, and then the vibration force generated can filter the filter plate 20, so as to avoid the sewage impurities sticking to the surface of the filter plate 20 and affecting the clogging of the sewage in the later stage.

[0026] The second embodiment is different from the first embodiment in that a conveying mechanism can be provided to discharge impurities from the filtered sewage, thereby preventing impurities from adhering to the inner wall of the discharge pipe 7 and causing blockage, thereby improving fluidity. A second rotating shaft 26 is rotatably installed inside the discharge pipe 7, and a circle of water receiving plates 27 is positioned and installed on the outer side surface of the second rotating shaft 26, wherein one circle of water receiving plates 27 is at equal angles, and each water receiving plate 27 is in the shape of an arc, and a first magnet 28 is installed on the outer surface of a circle of water receiving plates 27. A cleaning rack 30 is slidably installed inside the discharge pipe 7, and a second magnet 29 is provided above the cleaning rack 30. The first magnet 28 corresponds to the top of the second magnet 29, and the first magnet 28 and the second magnet 29 have the same magnetic pole. The inside of the discharge pipe 7 is connected to one end of two second return springs 31, and the two second return springs 31 have the same structure, and the other end of the two second return springs 31 is connected to the cleaning rack 30.

[0027] like Figures 1-11 As shown, after the filter plate 20 filters and separates the sewage impurities, the screened impurities will be transported to the inside of the discharge pipe 7 through the arc-shaped valve body 1, and then the filtered and screened impurities will be discharged to the outside of the bottom of the valve body 1 through the discharge pipe 7, and the impurities discharge can be completed. When the fluid impurities are transported to the inside of the discharge pipe 7 through the sewage, the transported sewage will simultaneously hit a circle of water receiving plates 27 to drive the second rotating shaft 26 to rotate inside the discharge pipe 7. At this time, a circle of rotating water receiving plates 27 will drive a circle of first magnets 28 and second magnets 29 to squeeze the cleaning rack 30 to make reciprocating movements inside the discharge pipe 7 through the principle of magnetic field repulsion. Not only can the cleaning rack 30 be used to clean and scrape the impurities stuck on the inner wall of the discharge pipe 7, but the vibration force of the cleaning rack 30 after resetting can also be used to vibrate and beat the discharge pipe 7, so as to prevent impurities from sticking to the inner wall of the discharge pipe 7 and affecting the later discharge use, thereby improving the convenience of the angle regulating valve in discharging sewage impurities.

[0028] The third embodiment is different from the second embodiment in that the external pipe 9 can be quickly and easily disassembled and installed without the need for positioning parts such as screws, thereby improving the efficiency of the angle regulating valve. The connecting flange 2 is internally provided with a limit block 15 which is slidably mounted via two first return springs 16, and the two limit blocks 15 on one side away from the connecting flange 2 are in an arc shape, and the outer ends of the two limit blocks 15 extend through the interior of the connecting disk 8. The two connecting disks 8 are symmetrically arranged about the vertical center line of the valve body 1, and the outer sides of the two connecting disks 8 are sealed with a pipeline 9, the outer ends of the two limit blocks 15 are in an arc shape, and the interior of the connecting disk 8 is slidably mounted with two pressing rods 10 via a tension spring 14, and the two The outer side surface of each pressing rod 10 is connected to one end of a tension spring 14, and the other end of the two tension springs 14 is connected to a connecting disk 8. The inner ends of the two pressing rods 10 are in an arc shape. The inside of the connecting disk 8 is connected to a circle of storage springs 13, and a circle of storage springs 13 away from the connecting disk 8 is connected to a top plate 11, wherein the top plate 11 is slidably installed inside the connecting disk 8, and a sealing airbag 12 is provided on the side of the top plate 11 away from the connecting disk 8, and the outer side surface of the sealing airbag 12 is fitly connected to the connecting flange 2.

[0029] like Figures 1-6 As shown, when it is necessary to quickly position and install the external pipe 9, it is only necessary to press the connecting disc 8 to retract and move. At this time, the two arc-shaped limit blocks 15 will be retracted and moved by the extrusion of the connecting disc 8, and then the two first return springs 16 can automatically bounce the two limit blocks 15 into the connecting disc 8, so that the position of the connected pipe 9 can be positioned and fixed, avoiding the pipe 9 from loosening and falling off due to vibration and collision during later use, and the stability is better. When the connecting disc 8 is installed on the outside of the connecting flange 2, the top plate 11 set inside the connecting disc 8 will be retracted and moved by the extrusion of the connecting flange 2, and then a circle of storage springs 13 will be squeezed at the same time to store force, so that the auxiliary pipe 9 can be quickly disassembled and replaced later. During the installation process of the connecting flange 2 and the connecting disc 8, the sealing airbag 12 set on the outside of the top plate 11 will seal the connection between the connecting flange 2 and the connecting disc 8 by squeezing, avoiding leakage of the connection between the connecting flange 2 and the connecting disc 8 after long-term use, and the sealing effect is better.

[0030] When the pipeline 9 needs to be quickly disassembled and replaced, the two pressing rods 10 are pressed to retract and move through the two tension springs 14. At this time, the two retracted pressing rods 10 will simultaneously squeeze and retract the two limit blocks 15 to the connecting flange 2. At this time, the force storage spring 13 after a circle of force storage will elastically reset the top plate 11 after the squeeze and retraction movement through its own elastic force, so as to facilitate the pushing and discharge of the connecting disk 8 to the connecting flange 2, so as to realize the quick disassembly and replacement of the pipeline 9, and the operation is more time-saving and labor-saving, thereby completing a series of tasks.
