Description

Technical Field

[0001] This utility model relates to the field of mud discharge valve technology, specifically an automatic flushing mud discharge valve. Background Technology

[0002] A sludge discharge valve is a valve specifically designed to discharge sludge, impurities, or particulate matter deposited at the bottom of pipes or equipment. It is commonly used in water treatment, municipal engineering, and industrial circulating water systems. Its main function is to periodically or continuously discharge sludge, sand, and suspended solids from the bottom of pipes, pools, sedimentation tanks, and wastewater treatment facilities to prevent clogging and ensure system efficiency. However, existing sludge discharge valves often employ a simple structure with only a main channel for sludge discharge. This single-channel design limits the valve's function to sludge discharge, lacking additional channels for the introduction and flow of flushing water, resulting in poor automatic flushing performance.

[0003] To overcome the aforementioned defects, existing technology (Chinese patent application number: 201721514060.0, application date: November 14, 2017) discloses a double-sealed sludge discharge valve with flushing function, including a sludge discharge valve body. A fixed base is provided at the bottom of the sludge discharge valve body. An inlet pipe is connected to one side wall of the sludge discharge valve body. A filter pipe is provided at the center inside the sludge discharge valve body. An outlet pipe is connected to the other side wall of the sludge discharge valve body. A flushing pipe is connected between the inlet pipe and the filter pipe. A sludge discharge pipe is connected to the bottom of the filter pipe. When the second solenoid valve on the inlet pipe is closed, the third solenoid valve on the flushing pipe and the first solenoid valve on the sludge discharge pipe are opened. At this time, the water in the inlet pipe will be transmitted to the sealing cover through the flushing pipe and discharged through the flushing plate to flush the filter pipe inside the sludge discharge valve body. The flushed sludge and sewage will be discharged through the sludge discharge pipe, so that the sludge discharge valve can realize automatic flushing, making the flushing of the filter pipe very convenient.

[0004] Although existing technology can achieve automatic flushing of mud discharge valves, the automatic flushing function of mud discharge valves requires the use of multiple solenoid valves, such as a second solenoid valve, a third solenoid valve, and a first solenoid valve. Since multiple solenoid valves need to work together in a specific logical sequence to achieve the automatic flushing function, any delay or error in the action of any solenoid valve will affect the normal operation of the entire flushing process, resulting in poor automatic flushing effect and failing to prevent the medium from leaking from the gap between the valve body and the sealing cover, thus reducing the sealing performance of the mud discharge valve.

[0005] Therefore, we proposed an automatic flushing and mud discharge valve that can effectively solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide an automatic flushing and sludge discharge valve to solve the problem mentioned in the background art. Currently, when using a sludge discharge valve, the automatic flushing function requires multiple solenoid valves, such as a second solenoid valve, a third solenoid valve, and a first solenoid valve. Since multiple solenoid valves need to work together in a specific logical sequence to achieve the automatic flushing function, any delay or error in the action of any solenoid valve will affect the normal operation of the entire flushing process, resulting in poor automatic flushing effect and failure to prevent the medium from leaking from the gap between the valve body and the sealing cover, thus reducing the sealing performance of the sludge discharge valve.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an automatic flushing and sludge discharge valve, comprising a valve body, a valve seat bolted to the top of the valve body, a diaphragm fixedly installed on the top of the valve seat, a valve cover movably connected to the top of the diaphragm, a plurality of screws penetrating the interior of the valve cover, with the ends of the screws inserted into the valve seat, a flushing pipe fixedly installed on the top right side of the valve body; a valve assembly for flushing control is provided on the left side of the valve seat, a first retaining seat is fixedly installed on the right side of the valve body, the first retaining seat having an inlet inside; a second retaining seat is fixedly installed at the bottom of the valve body, the bottom of the second retaining seat having a sludge discharge port, a valve stem is provided inside the valve body, and a valve disc is fixedly installed at the bottom of the valve stem.

[0008] As a preferred technical solution of this application, the valve assembly includes a pneumatic valve body, an installation rod is fixedly installed on the bottom right side of the pneumatic valve body, and the end of the installation rod is fixedly connected to a valve seat. A pneumatic connecting rod is provided on the top right side of the pneumatic valve body.

[0009] As a preferred technical solution of this application, a sealing ring is fixedly connected to the outer wall of the valve disc, and a buffer plate is fixedly installed on the top of the valve disc. The buffer plate is designed with a hollow structure. The hollow structure inside the buffer plate can reduce the direct impact force of the medium on the valve disc to a certain extent, avoid the valve disc from vibrating violently or being damaged under the impact of the medium, and ensure the stability of the valve disc during the sludge flushing process.

[0010] As a preferred technical solution of this application, the first card holder and the valve body are connected. The outer rings of both the first card holder and the second card holder are provided with a number of screw holes, which facilitates the connection of external pipes.

[0011] As a preferred technical solution of this application, the pneumatic connecting rod and the valve stem are tightly fitted together, and the valve stem is movably connected to the valve seat and the valve cover. The pneumatic connecting rod does not apply an upward thrust to the valve stem. At this time, the valve disc is tightly fitted to the bottom of the valve seat, separating the inside of the valve body from the mud discharge port.

[0012] As a preferred technical solution of this application, the valve disc and the sealing ring are tightly fitted, the sealing ring and the valve body are movably connected, and the sealing ring is made of nitrile rubber. The sealing ring made of nitrile rubber has good elasticity and flexibility. During the process of the valve disc pressing the valve seat, the sealing ring will undergo a certain degree of elastic deformation to fill the tiny gap between the valve disc and the valve body.

[0013] As a preferred technical solution of this application, the buffer plate and the valve disc are fixedly connected. The buffer plate is made of polytetrafluoroethylene (PTFE) material. The buffer plate made of PTFE material is lightweight and has good corrosion resistance, which can ensure that the buffer plate works stably for a long time in various corrosive media environments, reducing maintenance and replacement costs.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This automatic flushing and sludge discharge valve, by setting a diaphragm, facilitates the prevention of medium leakage from the gap between the valve cover and the valve seat, ensuring the sealing performance of the sludge discharge valve. Furthermore, the inclusion of a pneumatic valve body, pneumatic connecting rod, and valve disc facilitates automatic control of the sludge discharge valve for flushing, enabling accurate and timely sludge discharge and flushing operations. Additionally, the inclusion of a sealing ring and buffer plate ensures good sealing performance, uniform flushing effect, and protection of the valve disc. Specific details are as follows:

[0015] 1. A diaphragm is installed, which acts as a seal between the valve cover and the valve seat, effectively preventing the medium from leaking from the gap between the valve cover and the valve seat, ensuring the sealing performance of the mud discharge valve, and avoiding the waste of the medium and pollution to the surrounding environment.

[0016] Furthermore, a pneumatic valve body, a pneumatic connecting rod, and a valve disc are installed. The pneumatic valve body is started or stopped by an external control panel, and the pneumatic connecting rod pushes the valve disc connected to the valve stem upward or downward to move the valve, thereby opening or closing the valve. In conjunction with flushing water entering the valve body through the inlet for high-pressure flushing, the automatic control flushing of the sludge discharge valve is realized, which can accurately and timely perform sludge discharge and flushing operations to ensure the normal operation of production.

[0017] 2. A sealing ring and a buffer plate are installed. The sealing ring, made of nitrile rubber, has good elasticity and flexibility, effectively preventing the medium from leaking from the gap between the valve disc and the valve body. The buffer plate is connected to the outer wall of the valve disc, which can not only reduce the direct impact force of the medium on the valve disc to a certain extent, but also ensure that the buffer plate works stably for a long time in various corrosive media environments, thus improving the reliability and service life of the mud discharge valve.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-6 The present invention provides the following technical solution:

[0027] Example 1: To address the issue that existing mud discharge valves on the market require multiple solenoid valves for automatic flushing, including a second, third, and first solenoid valve, to function automatically. Since these valves must work in a specific logical sequence to achieve automatic flushing, any delay or error in the action of any one of them will affect the entire flushing process, resulting in poor automatic flushing performance and failing to prevent media leakage from the gap between the valve body and the sealing cover, thus reducing the sealing performance of the mud discharge valve. This example discloses an automatic flushing mud discharge valve with the following technical details, which can be found in the attached document. Figure 1 -Appendix Figure 5The valve body includes a valve body 1, a valve seat 2 bolted to the top of the valve body 1, a diaphragm 6 fixedly mounted on the top of the valve seat 2, a valve cover 3 movably connected to the top of the diaphragm 6, and several screws 10 penetrating the interior of the valve cover 3, with the ends of the screws 10 inserted into the valve seat 2. A flushing pipe 5 is fixedly mounted on the top right side of the valve body 1. A valve assembly for flushing control is provided on the left side of the valve seat 2. A first retaining seat 9 is fixedly mounted on the right side of the valve body 1, with an inlet 11 inside the first retaining seat 9. A second retaining seat 12 is fixedly mounted on the bottom of the valve body 1, with a drain outlet at the bottom of the second retaining seat 12. The valve body 1 has a valve stem 7 inside the mud port 1, and a valve disc 8 is fixedly installed at the bottom of the valve stem 7. The valve assembly includes a pneumatic valve body 4, a mounting rod 14 is fixedly installed at the bottom right side of the pneumatic valve body 4, and the end of the mounting rod 14 is fixedly connected to the valve seat 2. A pneumatic connecting rod 15 is provided at the top right side of the pneumatic valve body 4. The first card seat 9 is connected to the valve body 1. The outer rings of the first card seat 9 and the second card seat 12 are provided with several screw holes. The pneumatic connecting rod 15 is tightly fitted to the valve stem 7, and the valve stem 7 is movably connected to the valve seat 2 and the valve cover 3.

[0028] When the valve is not flushing or discharging sludge, the pneumatic valve body 4 is in the closed state, and the pneumatic connecting rod 15 does not apply an upward thrust to the valve stem 7. At this time, the valve disc 8 is tightly fitted to the bottom of the valve seat 2, isolating the inside of the valve body 1 from the sludge discharge port 13. The medium normally enters the valve body 1 from the inlet 11 and flows to the subsequent system through the valve body 1. The diaphragm 6 between the valve cover 3 and the valve seat 2 plays a sealing role, effectively preventing the medium from leaking from the gap between the valve cover 3 and the valve seat 2, ensuring the sealing performance of the sludge discharge valve, and avoiding the waste of medium and pollution to the surrounding environment. When sludge discharge is required, the operator starts the pneumatic valve body 4 through the external control panel. The pneumatic connecting rod 15 pushes the valve stem 7 upward, and the valve stem 7 drives the valve disc 8 to move upward, causing the valve disc 8 to leave the valve seat 2, and the valve opens. After the valve opens, the medium in the valve body 1, under its own pressure, partially flows through the valve body 1. The sludge is discharged through the sludge discharge port 13, carrying away the sludge and other impurities accumulated at the bottom of the valve body 1. Since the first retainer 9 is connected to the valve body 1, the medium at the inlet 11 continuously enters the valve body 1, providing power for sludge discharge and ensuring smooth sludge discharge. At the same time as sludge discharge, flushing water enters the interior of the valve body 1 through the inlet 11, performing high-pressure flushing on the inner wall of the valve body 1, valve disc 8, valve seat 2, and other parts, washing away residual sludge and other impurities attached to these parts, ensuring unobstructed flow. The flushing water is discharged from the sludge discharge port 13 along with the sludge discharge medium. After sludge discharge and flushing are completed, the pneumatic valve body 4 is closed by the external control panel, causing the valve disc 8 to re-fit tightly against the bottom of the valve seat 2. The valve is closed, the sludge discharge and flushing process ends, and the medium resumes normal flow. This realizes automatic control flushing of the sludge discharge valve, enabling accurate and timely sludge discharge and flushing operations, ensuring normal production operation.

[0029] Example 2: This example discloses an automatic flushing and sludge discharge valve that achieves good sealing performance, uniform flushing effect, and protection of valve disc 8. See attached document for details. Figure 1 -Appendix Figure 2 and attached Figure 4 -Appendix Figure 6 A sealing ring 16 is fixedly connected to the outer wall of the valve disc 8, and a buffer plate 17 is fixedly installed on the top of the valve disc 8. The buffer plate 17 is designed with a hollow structure. The valve disc 8 and the sealing ring 16 are tightly fitted together, and the sealing ring 16 is movably connected to the valve body 1. The sealing ring 16 is made of nitrile rubber. The buffer plate 17 is fixedly connected to the valve disc 8 and is made of polytetrafluoroethylene.

[0030] A sealing ring 16 is tightly fitted to the outer wall of the valve disc 8. The sealing ring 16, made of nitrile rubber, has good elasticity and flexibility. During the process of the valve disc 8 pressing against the valve seat 2, the sealing ring 16 will undergo a certain degree of elastic deformation, filling the tiny gap between the valve disc 8 and the valve body 1. This effectively prevents the medium from leaking from the gap between the valve disc 8 and the valve body 1, ensuring the sealing performance of the valve in the closed state, allowing the medium to flow normally along the predetermined path, and effectively preventing medium leakage. When flushing water enters the valve body 1 for flushing, a buffer plate 17 is connected to the outer wall of the valve disc 8. The buffer plate 17, made of polytetrafluoroethylene, is lightweight and has good corrosion resistance. It is also designed with a hollow structure, which can not only reduce the direct impact force of the medium on the valve disc 8 to a certain extent, avoiding the valve disc 8 from violently vibrating or being damaged under the impact of the medium, and ensuring the stability of the valve disc 8 during the mud discharge flushing process, but also ensure that the buffer plate 17 can work stably for a long time in various corrosive media environments, reducing maintenance and replacement costs. This achieves good sealing performance, uniform flushing effect, and protection of the valve disc 8, improving the reliability and service life of the mud discharge valve.
