Description

Technical Field

[0001] The present invention relates to the technical field of copper valves, and specifically to a copper valve with a clogging prevention function. Background Art

[0002] A copper valve refers to a valve mainly made of copper or copper alloy. As a key component in fluid transportation and control systems, the types of copper valves mainly include globe valves, ball valves, and plug valves, which are widely used in fields such as water supply and drainage, heating, petrochemical, and papermaking, and are especially suitable for industrial or civil fluid control scenarios that require corrosion resistance, wear resistance, and high reliability, and can meet various working conditions. There are defects in the prior art: when the existing copper valve transports fluid, the fluid will contain suspended particles. When a large amount of suspended particles accumulate in the valve body, it is difficult to discharge them, which will cause the valve body to be blocked, ultimately affecting the use of the valve body. Summary of the Invention

[0003] The purpose of the present invention is to provide a copper valve with a clogging prevention function to solve the problems raised in the prior art.

[0004] To achieve the above purpose, the present invention provides the following technical solution: The copper valve includes a valve body structure. A plug cover is installed at one end of the valve body structure. A plug structure is rotatably connected inside the valve body structure. A protective shell is installed outside the plug cover. A driving motor is installed on one side of the protective shell. The output shaft of the driving motor is installed on the plug structure. A handwheel is installed at one end of the driving motor. The driving motor is connected to a control system.

[0005] The plug structure includes a plug shell. The plug shell is installed on one side of the plug cover. A valve stem is rotatably connected inside the plug shell. A valve core is installed on one side of the valve stem. The valve core rotates inside the valve body structure. A through groove is provided on the valve core. A guide plate is installed on one side of the through groove. A baffle is installed on the other side of the through groove. A sewage discharge port is provided at the bottom of the valve core. A first water inlet groove is provided on the valve core. A second water inlet groove is provided on one side of the first water inlet groove. The second water inlet groove communicates with the bottom of the valve core.

[0006] The valve body structure includes a valve main body. The valve core rotates inside the valve main body. A slag collection structure and a slag discharge structure are installed inside the valve main body. A drain port is provided at the bottom of the valve main body. An air vent is provided on one side of the valve main body.

[0007] The slag collection structure includes an inner pipe. The inner pipe is installed inside the valve main body. A spiral groove is provided on the inner wall of the inner pipe. A first support plate is installed inside the inner pipe. A first rotating shaft is installed inside the first support plate. A drainage fan is installed at one end of the first rotating shaft. A slag guide plate is installed at one end of the inner pipe. When transporting fluid, the fluid will drive the drainage fan to rotate, causing the fluid in the inner pipe to generate a vortex. The centrifugal force generated will cause the suspended particles in the fluid to move towards the spiral groove. The suspended particles move along the spiral groove and are finally transported from the slag guide plate to the guide plate. The suspended particles are blocked by the baffle and stay inside the valve core.

[0008] The slag discharging structure includes a fixed block, which is installed at the bottom of the valve body. A residence structure and a negative pressure structure are installed on one side of the fixed block. A rotating structure is installed on one side of the valve core. The rotating structure slides within the residence structure. A moving structure is slidably connected inside the negative pressure structure. A sewage discharging structure is installed inside the fixed block. The negative pressure structure is communicated with the sewage discharging structure, and the residence structure is communicated with the sewage discharging structure.

[0009] The residence structure includes a flushing groove, which is installed on one side of the fixed block. A sliding groove is arranged on one side of the flushing groove. A flushing water port is arranged at the bottom of the flushing groove. The flushing water port is communicated with the sewage discharging structure. A sealing plate is slidably connected inside the flushing groove. A positioning groove is arranged on one side of the sealing plate. A first spring is installed at one end of the sealing plate, and the other end of the first spring is installed at one end of the flushing groove. A sliding groove and a fixing plate are installed on the fixed block. A limiting block is slidably connected inside the sliding groove. The limiting block is adapted to the positioning groove. One end of the limiting block is rotatably connected to a first connecting rod. One side of the first connecting rod is rotatably connected to a second connecting rod. The second connecting rod rotates on the fixing plate. The rotating structure slides within the flushing groove. When the copper valve is opened, the control system controls the output shaft of the driving motor to rotate. The output shaft drives the valve stem to rotate. The valve stem drives the valve core to rotate. The valve core drives the semi-gear to rotate. The semi-gear drives the pushing block to slide within the flushing groove. The pushing block drives the sealing plate to slide within the flushing groove. At this time, the first spring is compressed. The fluid flows from the first water inlet groove to the second water inlet groove, then from the second water inlet groove to the flushing groove, from the flushing groove to the flushing water port, and finally from the flushing water port to the slag storage cavity. When the sealing plate moves towards one end of the flushing groove, the first extension plate drives the first pushing column to move. The first pushing column abuts against the connection between the first connecting rod and the second connecting rod. The first pushing column drives the first connecting rod to rotate. The first connecting rod drives the limiting block to slide within the sliding groove. The limiting block slides towards the direction close to the positioning groove. When the sealing plate moves to the bottom of the flushing groove, the limiting block inserts into the positioning groove, and the sealing plate blocks the second water inlet groove. When the copper valve is closed, since the limiting block is inserted into the positioning groove, the sealing plate will stay in place. The fluid will flow from the second water inlet groove to the flushing groove. When the second pushing column abuts against the connection between the first connecting rod and the second connecting rod, the first pushing column drives the first connecting rod to rotate. The first connecting rod drives the limiting block to slide within the sliding groove. The limiting block slides away from the positioning groove. When the pushing block moves to the other end of the flushing groove, the limiting block leaves the positioning groove. The first spring stretches and drives the sealing plate to slide within the flushing groove. The sealing plate slides towards the other end of the flushing groove. When the sealing plate moves to the other end of the flushing groove, the sealing plate blocks the second water inlet groove.

[0010] The negative pressure structure includes an exhaust duct which is installed inside a fixed block. The exhaust duct is in communication with an air outlet. An adsorption duct is installed on one side of the exhaust duct. A moving structure is installed inside the adsorption duct.

A second support plate is installed inside the exhaust duct. A third rotating shaft is installed inside the second support plate. An exhaust fan is installed at one end of the third rotating shaft. A second bevel gear is installed on the third rotating shaft. The first bevel gear meshes with the second bevel gear. When the copper valve opens and closes, the valve core rotates, the valve core drives the half gear to rotate, the half gear drives the spur gear to rotate, the spur gear drives the second rotating shaft to rotate, the second rotating shaft drives the first bevel gear to rotate, the first bevel gear drives the second bevel gear to rotate, the second bevel gear drives the third rotating shaft to rotate, and the third rotating shaft drives the exhaust fan to rotate. The exhaust fan can accelerate the air flow inside the exhaust duct, generating negative pressure inside the adsorption duct. The negative pressure will adsorb the sliding rod to slide inside the support block. The sliding rod slides in a direction away from the support block, and the sliding rod drives the slag blocking block to move until the fluid drives the particles to flow from the connecting pipe into the slag storage cavity.

[0011] The sewage discharge structure includes a slag storage cavity which is installed inside the fixed block. The slag storage cavity is in communication with the connecting pipe and the water flushing port. A bent pipe is installed at the bottom of the slag storage cavity. A siphon pipe is installed at one end of the bent pipe. A slag discharge pipe is installed at one end of the siphon pipe, and the slag discharge pipe is in communication with a drain port. When the liquid level inside the slag storage cavity rises, with the liquid flow generated by the attraction of the liquid inside the valve cavity by the siphon pipe, a large amount of wastewater carrying particles will flow out along the siphon pipe into the slag discharge pipe and flow out from the drain port.

[0012] The rotating structure includes a half gear which is installed on one side of the valve core. The half gear meshes with the spur gear. A support rod, a first extension plate and a second extension plate are installed on the outer wall of the half gear. A push block is installed at one end of the support rod, and the push block slides inside the flushing groove.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. The present invention adopts the collaborative design of spiral grooves and guide plates to achieve efficient separation of fluids containing suspended particles and continuous slag discharge. It utilizes the turbulent effect generated by the fluid in the spiral grooves to continuously scour the pipe wall, preventing the attachment of particles and dirt. The guide plates are installed at a certain angle and staggered with the spiral grooves to guide the fluid and particles into the slag collection area, thereby keeping the fluid in the pipeline clean, preventing particles from accumulating in the valve body and causing blockage of the valve body, and reducing the manual cleaning and maintenance costs. 2. The present invention adopts negative pressure technology, which can utilize negative pressure to open the slag discharge channel in the valve body when the copper valve opens and closes, and transport the particles accumulated in the slag collection area to the slag discharge area, facilitating the discharge of particles in the fluid, achieving automatic cleaning, without the need for additional power sources or mechanical devices, and the structure is more concise and reliable. 3. The present invention adopts siphon technology, which can automatically drain water into the siphon when the copper valve opens and closes. With the liquid flow generated by the attraction of the liquid in the valve cavity by the siphon, a large amount of waste water carrying particles will flow out along the siphon. During the continuous siphon, the shear force formed on the valve cavity wall surface and around the valve core can scour the attached fine particles into the fluid, ensuring that the particles do not stay in the valve again, and realizing the automatic discharge of the residue in the valve cavity.

The fluid will flow in the valve body 31, and the fluid will drive the drainage fan 324 to rotate, which will cause the fluid in the inner pipe 321 to generate a vortex. The generated centrifugal force will cause the suspended particles in the fluid to move towards the spiral groove 322. The suspended particles move along the spiral groove 322 and finally are conveyed to the guide plate 15 by the slag guide plate 325. The suspended particles are blocked by the baffle 14 and stay in the valve core 13.

[0029] When the copper valve is closed, since the limiting block 3325 is inserted into the positioning groove, the sealing plate 3322 will stay in place. The fluid will flow from the second water inlet groove to the flushing groove 3321 and finally flow into the slag storage cavity 3341. When the second push rod abuts against the connection between the first connecting rod 3326 and the second connecting rod 3327, the first push rod drives the first connecting rod 3326 to rotate. The first connecting rod 3326 drives the limiting block 3325 to slide in the sliding groove 3324. The limiting block 3325 slides away from the positioning groove.

The first bevel gear 3334 drives the second bevel gear 3335 to rotate. The second bevel gear 3335 drives the third rotating shaft to rotate. The third rotating shaft drives the exhaust fan 3337 to rotate. The exhaust fan 3337 can accelerate the air flow in the exhaust duct 3331, creating a negative pressure in the adsorption duct 3332. The negative pressure will adsorb the sliding rod 3362 to slide in the support block 3361. The sliding rod 3362 slides away from the support block 3361. The sliding rod 3362 drives the slag blocking block 3363 to move until the fluid drives the particles to flow from the connecting pipe 3336 into the slag storage cavity 3341.

[0031] When the fluid flows from the flushing groove 3321 into the slag storage cavity 3341 and the liquid level in the slag storage cavity 3341 rises, with the liquid flow generated by the attraction of the liquid in the valve cavity by the siphon 3343, a large amount of wastewater carrying particles will flow out along the siphon 3343 into the slag discharge pipe 3344 and flow out from the drain port 34, realizing the automatic discharge of the residue in the valve cavity.

[0032] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and without departing from the spirit or basic characteristics of the present invention, the present invention can be implemented in other specific forms. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be encompassed within the present invention. Any reference signs in the claims should not be regarded as limiting the claimed rights.
