Description

Technical Field

[0001] This utility model relates to the field of regulating valve technology, and in particular to an acid discharge regulating valve for a special rubber acid tank discharge port. Background Technology

[0002] With the rapid development of the industrial sector, many production processes generate acidic wastewater. If this acidic wastewater is not properly treated, it will cause serious pollution to the environment. In order to effectively control the discharge of acidic wastewater and ensure environmental safety, the acid discharge regulating valve of the special rubber acid tank discharge port plays a vital role.

[0003] In the discharge system of equipment such as special rubber acid tanks, acid discharge regulating valves play a crucial role. Traditional acid discharge regulating valves are usually made of metal or plastic materials. Although they have been treated with acid resistance, their sealing performance deteriorates and even leaks occur after long-term use. Therefore, they need to be inspected and maintained every once in a while. However, when inspecting existing regulating valves, it is necessary to first remove the regulating valve from the delivery pipe before inspection and maintenance can be carried out, which is very inconvenient. To address this, an acid discharge regulating valve for the discharge port of special rubber acid tanks has been designed. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies by proposing a special rubber acid tank discharge regulating valve.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A special rubber acid tank discharge regulating valve includes a regulating chamber. A Z-shaped plate is fixedly connected to the inner side of the regulating chamber. A through hole is formed in the middle of the Z-shaped plate. An installation hole is formed at the top of the regulating chamber near the through hole. Four fixing bolts are fixedly connected to the top of the regulating chamber near the installation hole, and a connecting plate is screwed to the four fixing bolts. A cylinder is fixedly connected to the top of the connecting plate. A partition plate is fixedly connected to the middle of the cylinder. A connecting rod is slidably sleeved in the middle of the partition plate. A sealing element is fixedly connected to the bottom of the connecting rod through the connecting plate. The sealing element is adapted to the through hole. The connecting plate has a circular hole in the middle that is adapted to the connecting rod. The top of the sealing element has a protrusion, and a second fluororubber sealing ring is fitted at the bottom of the protrusion. The bottom circumferential surface of the sealing element has four conical grooves at equal intervals. The opening of the conical grooves is smaller at the top and larger at the bottom. When the sealing element rises higher, the flow rate is greater. The bottom of the sealing element is fixedly connected to a top rod. The top rod can prevent the fluororubber sealing gasket from blocking the bottom of the through hole when the sealing element rises during normal use.

[0007] As a further embodiment of this utility model, a sealing filler is installed on the inner side of the cylinder at the bottom of the partition, and a circular hole adapted to the connecting rod is opened in the middle of the sealing filler.

[0008] As a further embodiment of this utility model, the top of the connecting rod is provided with a threaded groove, and the thread of the top of the connecting rod extends through the top of the cylinder. A screw nut that matches the threaded groove is fixedly sleeved at the middle of the top of the cylinder, and a handwheel is fixedly connected to the top of the connecting rod.

[0009] As a further embodiment of this utility model, a first fluororubber sealing ring is provided between the connecting plate and the Z-shaped plate, and the first fluororubber sealing ring has a hole in the middle that matches the mounting hole. The first fluororubber sealing ring can improve the sealing performance between the connecting plate and the regulating chamber.

[0010] As a further embodiment of this utility model, a square rod is fixedly connected between the top and bottom of the side of the adjustment chamber away from the Z-shaped plate, and a lifting plate is slidably sleeved on the square rod. One end of the lifting plate has a square hole adapted to the square rod, and the other end of the top of the lifting plate is fixedly connected to a disc. A fluororubber sealing gasket is fixedly connected to the top of the disc, and the fluororubber sealing gasket is adapted to the through hole. A spring is sleeved on the square rod at the bottom of the lifting plate. Through the setting of the spring and the fluororubber sealing gasket, the through hole is automatically blocked when the connecting plate and the inside of the cylinder need to be inspected, which facilitates the user's inspection and maintenance.

[0011] As a further embodiment of this utility model, an inlet pipe is fixedly connected to one end of the regulating chamber near the square rod, and a first flange is fixedly connected to the other end of the inlet pipe.

[0012] As a further embodiment of this utility model, the end of the regulating chamber away from the square rod is fixedly connected to a liquid outlet pipe, and the other end of the liquid outlet pipe is fixedly connected to a second flange.

[0013] The beneficial effects of this utility model are as follows:

[0014] This utility model utilizes a lifting plate, a spring-loaded fluororubber gasket, and sealing components. When the connecting plate, sealing components, and cylinder require maintenance, rotating the handwheel raises the sealing component to its highest position. At this point, the fluororubber gasket, under the pressure of the spring and acid, tightly seals the through hole. This ensures that disassembly of the connecting plate and other components is unaffected, effectively solving the problems of difficult and cumbersome maintenance mentioned in the background technology. Furthermore, it eliminates the need for disassembly and additional operations during maintenance and repair, making the maintenance process convenient and fast, improving the work efficiency of maintenance personnel, and enhancing the practicality of the regulating valve.

[0021] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0022] Reference Figures 1-4A special rubber acid tank discharge regulating valve includes a regulating chamber 1. A Z-shaped plate 2 is fixedly connected to the inner side of the regulating chamber 1. A through hole 201 is opened in the middle of the Z-shaped plate 2. An installation hole is opened at the top of the regulating chamber 1 near the through hole 201. Four fixing bolts 4 are fixedly connected to the top of the regulating chamber 1 near the installation hole, and a connecting plate 5 is screwed to the four fixing bolts 4. A cylinder 501 is fixedly connected to the top of the connecting plate 5. A partition plate 502 is fixedly connected to the middle of the cylinder 501. A connecting rod 6 is slidably sleeved in the middle of the partition plate 502. A sealing element 7 is fixedly connected to the bottom of the connecting rod 6 through the connecting plate 5. Adapted to the through hole 201, the connecting plate 5 has a round hole in the middle that is adapted to the connecting rod 6. The top of the sealing element 7 is provided with a protrusion, and a second fluororubber sealing ring 701 is fitted at the bottom of the protrusion. Four conical grooves 702 are evenly spaced on the bottom circumferential surface of the sealing element 7. The conical grooves 702 are provided so that the flow rate will increase as the sealing element 7 rises. A top rod 703 is fixedly connected to the bottom of the sealing element 7. The top rod 703 is provided so that when the sealing element 7 rises and the flow rate increases, the fluororubber sealing gasket 304 can be prevented from rising and blocking the through hole 201.

[0023] In this embodiment, a sealing filler 503 is installed on the inner side of the cylinder 501 at the bottom of the partition 502, and a circular hole adapted to the connecting rod 6 is opened in the middle of the sealing filler 503.

[0024] In this embodiment, the top of the connecting rod 6 is provided with a threaded groove 602, and the thread of the top of the connecting rod 6 passes through the top of the cylinder 501. A screw nut that matches the threaded groove 602 is fixedly sleeved at the middle of the top of the cylinder 501. A handwheel 601 is fixedly connected to the top of the connecting rod 6. Through the setting of the threaded groove 602, the rotation of the handwheel 601 can drive the sealing element 7 to rise and fall.

[0025] In this embodiment, a first fluororubber sealing ring 401 is provided between the connecting plate 5 and the Z-shaped plate 2, and the first fluororubber sealing ring 401 has a hole in the middle that matches the mounting hole. The first fluororubber sealing ring 401 can improve the sealing performance between the connecting plate 5 and the regulating chamber 1.

[0026] In this embodiment, a square rod 3 is fixedly connected between the top and bottom of the end of the regulating chamber 1 away from the Z-shaped plate 2, and a lifting plate 301 is slidably sleeved on the square rod 3. One end of the lifting plate 301 has a square hole adapted to the square rod 3, and the other end of the top of the lifting plate 301 is fixedly connected to a disc 303. A fluororubber sealing gasket 304 is fixedly connected to the top of the disc 303, and the fluororubber sealing gasket 304 is adapted to the through hole 201. A spring 302 is sleeved on the bottom of the square rod 3 at the bottom of the lifting plate 301. Through the arrangement of the lifting plate 301, spring 302, disc 303 and fluororubber sealing gasket 304, when the sealing element 7 leaves the through hole 201, under the action of the spring 302 and the acid pressure, the fluororubber sealing gasket 304 can tightly block the through hole 201 to prevent the flow of acid. The fluororubber sealing gasket 304, the first fluororubber sealing ring 401 and the sealing filler 503 are all acid-resistant and can prevent corrosion by acid.

[0027] In this embodiment, an inlet pipe 101 is fixedly connected to one end of the regulating chamber 1 near the square rod 3, and a first flange 102 is fixedly connected to the other end of the inlet pipe 101.

[0028] In this embodiment, the end of the regulating chamber 1 away from the square rod 3 is fixedly connected to the liquid outlet pipe 103, and the other end of the liquid outlet pipe 103 is fixedly connected to the second flange 104.

[0029] Working Principle: All internal components of this control valve are acid-resistant to improve the device's service life. During installation, one end of the inlet pipe 101 is connected to the acid outlet pipe, and one end of the outlet pipe 103 is connected to the delivery pipe. In use, rotating the handwheel 601 causes the connecting rod 6 to move the sealing element 7 up and down. When the second fluororubber sealing ring 701 is tightly against the through hole 201, the acid flow can be cut off. When acid flow is needed, the handwheel 601 raises the sealing element 7. The conical groove 702 ensures that when the seal... The higher component 7 rises, the greater the flow rate, thus controlling the flow. When internal components are damaged and need replacement after prolonged use, the handwheel 601 is turned to move component 7 away from the through hole 201. At this time, when the spring 302 extends, the fluororubber gasket 304 is pressed tightly against the bottom of the through hole 201. Combined with the pressure of the acid, the disc 303 and the fluororubber gasket 304 are tightly pressed against the through hole 201, thus cutting off the flow of acid. By tightening the fixing bolt 4, the connecting plate 5 and the cylinder 501 can be disassembled, facilitating user maintenance and repair.
