Description

Technical Field

[0001] The invention belongs to the technical field of regulating valves, and in particular relates to a continuous sewage discharge regulating valve. Background Art

[0002] A regulating valve is a device used to control the flow, pressure or flow direction of a fluid. It can adjust the valve opening as needed to accurately control the amount or pressure of the fluid passing through the pipeline. A regulating valve is usually composed of a valve body, a valve core, a valve seat, a valve stem, an actuator and other components. It is used for fluid control and regulation operations in industries such as industry, construction, and manufacturing. During application, the valve opening is automatically adjusted according to the control signal in the automation system to achieve regulation of medium flow, pressure, temperature and liquid level. When discharging sewage, the regulating valve can adjust the fluid flow and pressure in the sewage pipeline. Especially when the sewage liquid or gas needs to maintain a certain pressure in the pipeline, the regulating valve can be used to adjust the pressure in the pipeline to ensure stable operation of the system. At the same time, the regulating valve can also adjust the flow rate of the fluid through the pipeline, and some sewage systems use regulating valves to prevent sewage backflow or control the direction of discharge.

[0003] In the process of continuous sewage discharge, the existing sewage regulating valve contains a large amount of impurities and particles. Even after being filtered by the filtering structure, the sewage still contains a certain amount of particles. During the operation of the regulating valve, the particles will remain inside the regulating valve, thereby affecting the working effect of the regulating valve. For example, when particles remain at the sealing port, it will affect the sealing effect inside the regulating valve, and the particle treatment cannot be achieved quickly during the continuous sewage discharge process. At the same time, some existing regulating valves, such as the manual adjustment part of the pneumatic regulating valve, are often designed on the pneumatic actuator. When there is a fault in the pneumatic actuator or the air chamber at the top, the manual adjustment part cannot be adjusted. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the above-mentioned prior art and provide a continuous sewage discharge regulating valve.

[0005] The technical solution adopted to solve the above technical problems is: providing a continuous sewage discharge regulating valve, comprising a regulating valve housing, the bottom of the regulating valve housing is fixedly connected to a bottom collecting mechanism, and the top of the regulating valve housing is provided with a top connecting mechanism;

[0006] An integrated limiting ring is fixedly connected to the center of the inner wall of the regulating valve housing, a sealing adjustment mechanism is installed on the longitudinal coaxial core between the bottom collecting mechanism and the top connecting mechanism, and a manual adjustment mechanism is fixedly connected to the outer wall of the sealing adjustment mechanism;

[0007] An adjusting air chamber mechanism is installed on the top of the manual adjusting mechanism, a connecting adjusting rod mechanism is installed between the top of the sealing adjusting mechanism and the adjusting air chamber mechanism, and a pneumatic actuator is installed between one side of the manual adjusting mechanism and the adjusting air chamber mechanism.

[0008] Furthermore, the bottom collecting mechanism includes an integrated connecting sleeve fixedly connected to the bottom of the regulating valve housing, a first rubber gasket is provided at the bottom of the integrated connecting sleeve, a collecting bucket is provided at the bottom of the first rubber gasket, a plurality of first bolt assemblies are installed through the integrated connecting sleeve, the first rubber gasket and the collecting bucket, and an electromagnetic valve is installed at the bottom of the collecting bucket.

[0009] Through the above technical solution, after sewage discharge stops for a period of time, when the pneumatic actuator is started again to start sewage discharge, the water flow carries the precipitated particles into the collection bucket, and then fills the precipitated particles into the collection bucket. At the same time, the air in the collection bucket is squeezed out and output from the top. When sewage discharge is subsequently stopped, the solenoid valve is opened to discharge the sewage and particles in the collection bucket, thereby realizing automatic filtering and cleaning of the particles without affecting the continuity of sewage discharge as much as possible.

[0010] Furthermore, the top connecting mechanism includes a sealing gasket and an upper valve cover installed on the top of the regulating valve housing, the inner wall of the sealing gasket is fixedly connected with a sealing layer, a plurality of second bolt assemblies are installed between the regulating valve housing and the upper valve cover, a sealing filler is installed on the inner wall of the upper valve cover, a blocking top cover is installed on the top of the upper valve cover, a plurality of third bolt assemblies are installed between the upper valve cover and the blocking top cover, and a second rubber gasket is installed between the regulating valve housing and the upper valve cover.

[0011] Through the above technical solution, during the rising and falling process of the sealing adjustment mechanism, the sealing adjustment mechanism and the top connecting mechanism can be sealed by the sealing pad, the sealing layer and the sealing filler to prevent sewage from overflowing.

[0012] Furthermore, the sealing adjustment mechanism includes a central valve stem, a valve core threaded cover is fixedly connected to the center of the outer wall of the central valve stem, a first sealing ring is sleeved on the bottom of the valve core threaded cover, a filter sleeve is spirally connected to the bottom of the central valve stem, a bottom sealing head is spirally connected to the bottom of the bottom sealing head, a second sealing ring is sleeved on the bottom of the bottom sealing head, an extension thin rod is fixedly connected to the top of the central valve stem, and a manual adjustment head is fixedly connected to the top of the extension thin rod.

[0013] Through the above technical solution, when the sealing adjustment mechanism rises, the valve core threaded cover and the integrated limit ring are separated, and the sewage enters from the filter sleeve at the bottom of the integrated limit ring, passes through the inside of the filter sleeve, and flows out from the filter sleeve at the top of the integrated limit ring. The particles in the sewage will be filtered twice by the filter sleeve, most of which will remain at the bottom and very few will remain inside the filter sleeve. At the same time, the sewage discharge volume can be controlled by controlling the rising height of the filter sleeve. After a period of sewage discharge, the pneumatic actuator drives the connection adjustment rod mechanism and the sealing adjustment mechanism to achieve reset seal. At this time, the sewage on the inlet side of the regulating valve housing tends to be stable, and the particles filtered outside the filter sleeve will gradually settle between the integrated connecting sleeve and the bottom sealing head.

[0014] Furthermore, the manual adjustment mechanism includes a support sleeve shell fixedly connected to the outer wall of the top connecting mechanism, a fixed support sleeve is installed on one side of the inner wall of the support sleeve shell, a sliding threaded sleeve is slidably connected to the inner wall of the fixed support sleeve, an extension limit sleeve is fixedly connected to one side of the center sleeve of the fixed support sleeve, and a fixed threaded sleeve is fixedly connected to the outer wall of the support sleeve shell on the side close to the fixed support sleeve, and an extrusion threaded rod is arranged between the fixed threaded sleeve and the extension limit sleeve.

[0015] Through the above technical solution, when the air chamber mechanism leaks or the pneumatic actuator fails, the extruded threaded rod is rotated to make the extruded threaded rod slide in the extension limit sleeve and squeeze the sliding threaded sleeve through the other end. At this time, the sliding threaded sleeve is fixed, and a wrench is used to drive the manual adjustment head, thereby driving the overall sealing adjustment mechanism and the connecting adjustment rod mechanism to rotate, and the sealing adjustment mechanism is adjusted up and down through the spiral structure of the threaded column and the sliding threaded sleeve to close or open the valve. More stable manual control can be achieved through the mechanical structure to avoid accidents.

[0016] Furthermore, one side of the sliding threaded sleeve is a planar structure, and the inner wall of the sleeve of the fixed support sleeve and the outer wall of the sliding threaded sleeve fit together.

[0017] Through the above technical solution, the planar structure of the sliding threaded sleeve ensures that during manual driving, one end of the extruded threaded rod can fit into the plane of the sliding threaded sleeve, thereby increasing the contact area to improve friction.

[0018] Furthermore, the regulating air chamber mechanism includes a lower diaphragm cover installed on the top of the manual adjusting mechanism, a fourth bolt assembly is installed between the lower diaphragm cover and both sides of the manual adjusting mechanism, a rubber diaphragm is fixedly connected to the top of the lower diaphragm cover, an upper diaphragm cover is provided on the top of the rubber diaphragm, a fifth bolt assembly is installed through the lower diaphragm cover, the rubber diaphragm and the upper diaphragm cover, and springs are fixedly connected on both sides of the inner surface of the bottom of the lower diaphragm cover.

[0019] Through the above technical solution, when sewage needs to be discharged, the air between the rubber diaphragm and the upper diaphragm cover is extracted through the pneumatic actuator, thereby pulling the rubber diaphragm up, driving the sealing adjustment mechanism and the connecting adjustment rod mechanism to rise to release the seal and realize sewage discharge operation. When sealing is required, air is filled between the rubber diaphragm and the upper diaphragm cover through the pneumatic actuator, thereby pushing the rubber diaphragm, the connecting adjustment rod mechanism and the sealing adjustment mechanism to reset and realize sealing.

[0020] Furthermore, the connecting adjustment rod mechanism includes an extension rod, the bottom of the extension rod is fixedly connected to a threaded column, the top of the extension rod is fixedly connected to a metal cover, and the top of the metal cover is spirally connected to a nut sleeve washer.

[0021] Through the above technical solution, the threaded column can be used to achieve the rise and fall of the threaded column in a spiral manner when the sliding threaded sleeve is fixed. The metal cover and the nut sleeve gasket can effectively increase the contact area with the rubber diaphragm, thereby avoiding damage to the rubber diaphragm.

[0022] The beneficial effects of the present invention are as follows: (1) The present invention designs a bottom collecting mechanism. After a period of sewage discharge, the connecting regulating rod mechanism and the sealing regulating mechanism are reset to complete the sealing. At this time, the sewage on the inlet side of the regulating valve housing tends to be stable, and the particles filtered outside the filter sleeve will gradually settle between the integrated connecting sleeve and the bottom sealing head. The solenoid valve is opened to release water. After a period of time, the pneumatic actuator controls the sealing regulating mechanism to rise again. At the moment when the bottom sealing head releases the seal, water flows into the collection bucket, and then the precipitated particles are filled into the collection bucket. Then the regulating valve starts to continue sewage discharge. When the sewage discharge seal is stopped later, the solenoid valve is opened to discharge the sewage and particles in the collection bucket, realizing automatic particle sorting. The particles are filtered and cleaned without affecting the continuity of sewage discharge as much as possible, thereby reducing the particles inside the regulating valve and improving the service life of the regulating valve; (2) The present invention designs a manual adjustment mechanism. When the regulating air chamber mechanism leaks or the pneumatic actuator fails, the threaded rod is rotated and squeezed to squeeze the sliding threaded sleeve through the other end. At this time, the sliding threaded sleeve is fixed. The manual adjustment head is driven by a wrench to drive the overall sealing adjustment mechanism and the connecting adjustment rod mechanism to rotate, and the sealing adjustment mechanism is adjusted up and down by the spiral structure of the threaded column and the sliding threaded sleeve to close or open the valve. More stable manual control can be achieved through the mechanical structure to avoid accidents. BRIEF DESCRIPTION OF THE DRAWINGS

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0035] like Figure 1-Figure 5 As shown, a continuous sewage discharge regulating valve of this embodiment includes a regulating valve housing 1, and a bottom collecting mechanism 2 is fixedly connected to the bottom of the regulating valve housing 1. The bottom of the regulating valve housing 1 is fixedly connected to the bottom of the regulating valve housing 1. The bottom of the integrated connecting sleeve 201 is provided with a first rubber gasket 202, and the bottom of the first rubber gasket 202 is provided with a collecting bucket 203. A plurality of first bolt assemblies 204 are installed through the integrated connecting sleeve 201, the first rubber gasket 202 and the collecting bucket 203. A solenoid valve 205 is installed at the bottom of the collecting bucket 203. After the sewage is discharged for a period of time, when the pneumatic actuator 9 is started again to start sewage discharge, the water flow carries the precipitated particles into the collecting bucket 203, and then the precipitated particles are filled into the collecting bucket 203. At the same time, the air in the collecting bucket 203 is squeezed out and discharged from the top. When the sewage discharge is stopped subsequently, the solenoid valve 205 is opened to discharge the sewage and particles in the collecting bucket 203, thereby automatically filtering and cleaning the particles.

[0036] like Figure 1-Figure 7 As shown, a top connecting mechanism 3 is provided on the top of the regulating valve housing 1, and the top connecting mechanism 3 includes a sealing gasket 301 and an upper valve cover 303 installed on the top of the regulating valve housing 1, and the inner wall of the sealing gasket 301 is fixedly connected with a sealing layer 302, and a plurality of second bolt assemblies 304 are installed between the regulating valve housing 1 and the upper valve cover 303, and a sealing filler 305 is installed on the inner wall of the upper valve cover 303, and a blocking top cover 306 is installed on the top of the upper valve cover 303, and a plurality of third bolt assemblies 307 are installed between the upper valve cover 303 and the blocking top cover 306, and a second rubber gasket 308 is installed between the regulating valve housing 1 and the upper valve cover 303. During the rising and falling process of the sealing regulating mechanism 5, the sealing regulating mechanism 5 and the top connecting mechanism 3 can be sealed by the sealing gasket 301, the sealing layer 302 and the sealing filler 305 to prevent sewage from overflowing.

[0037] like Figures 1-8As shown, an integrated limiting ring 4 is fixedly connected to the center of the inner wall of the regulating valve housing 1, and a sealing adjustment mechanism 5 is installed on the longitudinal coaxial core between the bottom collecting mechanism 2 and the top connecting mechanism 3. The sealing adjustment mechanism 5 includes a central valve stem 501, a valve core threaded cover 502 is fixedly connected to the center of the outer wall of the central valve stem 501, a first sealing ring 503 is sleeved on the bottom of the valve core threaded cover 502, a filter sleeve 504 is spirally connected to the bottom of the valve core threaded cover 502, a bottom sealing head 505 is spirally connected to the bottom of the central valve stem 501, a second sealing ring 506 is sleeved on the bottom of the bottom sealing head 505, an extension rod 507 is fixedly connected to the top of the extension rod 507, and a manual adjustment head 508 is fixedly connected to the top of the extension rod 507. When the sealing adjustment mechanism 5 rises, The valve core threaded cover 502 and the integrated limit ring 4 are separated, and the sewage enters from the filter sleeve 504 at the bottom of the integrated limit ring 4, passes through the inside of the filter sleeve 504 and flows out from the filter sleeve 504 at the top of the integrated limit ring 4. The particles in the sewage will be filtered twice by the filter sleeve 504, most of which will remain at the bottom and very few will remain inside the filter sleeve 504. At the same time, the sewage discharge volume can be controlled by controlling the rising height of the filter sleeve 504. After a period of sewage discharge, the pneumatic actuator 9 drives the connecting adjustment rod mechanism 8 and the sealing adjustment mechanism 5 to achieve reset sealing. At this time, the sewage on the inlet side of the regulating valve housing 1 tends to be stable, and the particles filtered outside the filter sleeve 504 will gradually settle between the integrated connecting sleeve 201 and the bottom sealing head 505.

[0038] like Figures 1-9As shown, the outer wall of the sealing adjustment mechanism 5 is fixedly connected to the manual adjustment mechanism 6, and the manual adjustment mechanism 6 includes a support sleeve 601 fixedly connected to the outer wall of the top connection mechanism 3, and a fixed support sleeve 602 is installed on one side of the inner wall of the support sleeve 601. The inner wall of the fixed support sleeve 602 is slidably connected to a sliding threaded sleeve 603, and one side of the central sleeve of the fixed support sleeve 602 is fixedly connected to an extension limit sleeve 604. The outer wall of the support sleeve 601 is fixedly connected to a fixed threaded sleeve 605 on the side close to the fixed support sleeve 602, and an extrusion threaded rod 606 is provided between the fixed threaded sleeve 605 and the extension limit sleeve 604. When the air chamber mechanism 7 leaks or the pneumatic actuator 9 fails, the extrusion threaded rod 606 is rotated to make the extrusion threaded rod 606 extend within the extension limit sleeve 604. The screw thread sleeve 603 is fixed to the bottom surface of the sealing member 503 and the screw thread sleeve 603 is fixed to the bottom surface of the sealing member 503. The screw thread sleeve 603 is fixed to the bottom surface of the sealing member 503 and the screw thread sleeve 603 is fixed to the bottom surface of the sealing member 503. The screw thread sleeve 603 is fixed to the bottom surface of the sealing member 503 and the screw thread sleeve 603 is fixed to the bottom surface of the sealing member 503. The screw thread sleeve 603 is fixed to the bottom surface of the sealing member 503 and the screw thread sleeve 603 is fixed to the bottom surface of the sealing member 503. The screw thread sleeve 603 is fixed to the bottom surface of the sealing member 503 and the screw thread sleeve 603 is fixed to the bottom surface of the sealing member 503.

[0039] like Figures 1-10As shown, an adjusting air chamber mechanism 7 is installed on the top of the manual adjusting mechanism 6, and the adjusting air chamber mechanism 7 includes a lower diaphragm cover 701 installed on the top of the manual adjusting mechanism 6, and a fourth bolt assembly 702 is installed between the lower diaphragm cover 701 and both sides of the manual adjusting mechanism 6, and a rubber diaphragm 703 is fixedly connected to the top of the lower diaphragm cover 701, and an upper diaphragm cover 704 is provided on the top of the rubber diaphragm 703. A fifth bolt assembly 705 is installed through the lower diaphragm cover 701, the rubber diaphragm 703 and the upper diaphragm cover 704, and springs 706 are fixedly connected on both sides of the bottom inner surface of the lower diaphragm cover 701. When sewage needs to be discharged, the air between the rubber diaphragm 703 and the upper diaphragm cover 704 is extracted by the pneumatic actuator 9, thereby pulling the rubber diaphragm 703 up, driving the sealing adjustment mechanism 5 and the connecting adjusting rod mechanism 8 to rise to release the seal and realize sewage discharge operation. When sealing is required, the rubber diaphragm 703 and the upper diaphragm cover are sealed by the pneumatic actuator 9. Air is filled between 704, thereby pushing the rubber diaphragm 703, the connecting adjusting rod mechanism 8 and the sealing adjusting mechanism 5 to reset and achieve sealing. A connecting adjusting rod mechanism 8 is installed between the top of the sealing adjusting mechanism 5 and the adjusting air chamber mechanism 7. The connecting adjusting rod mechanism 8 includes an extension rod 801, and the bottom of the extension rod 801 is fixedly connected with a threaded column 802, and the top of the extension rod 801 is fixedly connected with a metal cover 803, and the top of the metal cover 803 is spirally connected with a nut sleeve gasket 804. The threaded column 802 can be used to achieve the rise and fall of the threaded column 802 in a spiral manner when the sliding threaded sleeve 603 is fixed. The metal cover 803 and the nut sleeve gasket 804 can effectively increase the contact area with the rubber diaphragm 703, thereby avoiding damage to the rubber diaphragm 703. A pneumatic actuator 9 is installed between one side of the manual adjusting mechanism 6 and the adjusting air chamber mechanism 7.

[0040] The working principle of this embodiment is as follows: when in use, filtered sewage will flow into one end of the regulating valve housing 1 and fill the cavity on one side of the regulating valve housing 1. When sewage needs to be discharged, the air between the rubber diaphragm 703 and the upper diaphragm cover 704 is extracted by the pneumatic actuator 9, thereby pulling the rubber diaphragm 703 up, and the rubber diaphragm 703 drives the metal cover 803 and the nut sleeve gasket 804 to rise, thereby realizing the overall sealing adjustment mechanism 5 to rise through the extension rod 801 and the threaded column 802. At this time, the valve core threaded cover 502 and the integrated limit ring 4 are separated, and sewage enters from the filter sleeve 504 at the bottom of the integrated limit ring 4, passes through the filter sleeve 504, and then flows out from the filter sleeve 504 at the top of the integrated limit ring 4. The particles in the sewage will be filtered twice by the filter sleeve 504, of which most of the particles will remain at the bottom and a very small part will remain inside the filter sleeve 504. At the same time, the sewage discharge amount can be controlled by controlling the rising height of the filter sleeve 504.

[0041] After a period of sewage discharge, air is filled between the rubber diaphragm 703 and the upper diaphragm cover 704 through the pneumatic actuator 9, thereby pushing the rubber diaphragm 703, the connecting adjustment rod mechanism 8 and the sealing adjustment mechanism 5 to reset. At this time, the valve core threaded cover 502 is sealed by the first sealing ring 503 and the integrated limit ring 4. At the same time, the bottom sealing head 505 is sealed by the second sealing ring 506 and the integrated connecting sleeve 201. At this time, the sewage on the inlet side of the regulating valve housing 1 tends to be stable, and the particles filtered outside the filter sleeve 504 will gradually settle. Between the integrated connecting sleeve 201 and the bottom sealing head 505, the solenoid valve 205 is opened to release water. After a period of time, the pneumatic actuator 9 controls the sealing adjustment mechanism 5 to rise again. At the moment when the bottom sealing head 505 releases the seal, water flows into the collection hopper 203, and then the precipitated particles are filled into the collection hopper 203. At the same time, the air in the collection hopper 203 is squeezed out and discharged from the top. Then the regulating valve starts to continue to discharge sewage. When the sewage discharge is stopped later, the solenoid valve 205 is opened to discharge the sewage and particles in the collection hopper 203.

[0042] When the air chamber mechanism 7 leaks or the pneumatic actuator 9 fails, the extruded threaded rod 606 is rotated to make the extruded threaded rod 606 slide in the extended limit sleeve 604 and squeeze the sliding threaded sleeve 603 through the other end. At this time, the sliding threaded sleeve 603 is fixed. The manual adjustment head 508 is driven by a wrench to rotate the overall sealing adjustment mechanism 5 and the connecting adjustment rod mechanism 8. The sealing adjustment mechanism 5 is adjusted up and down through the spiral structure of the threaded column 802 and the sliding threaded sleeve 603 to close or open the valve. More stable manual control can be achieved through the mechanical structure to avoid accidents.

[0043] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
