Description

Technical Field

[0001] This utility model relates to the field of electrically controlled discharge valve technology, and in particular to a liquid electrically controlled discharge valve for hydrogen peroxide production. Background Technology

[0002] Hydrogen peroxide, commonly known as hydrogen peroxide aqueous solution (colorless, odorless, and transparent), is widely used as a strong oxidant and disinfectant in sterilization, disinfection, sewage treatment, dyeing, bleaching, and other fields. There are various industrial production methods for hydrogen peroxide, such as the electrolytic ammonium persulfate ((NH4)2S2O8) method, the isopropanol (CH3-CH-OH-CH3) oxidation method, the oxygen cathode electrolytic reduction method, the direct hydrogen-oxygen synthesis method, and the anthraquinone method, which is currently the most widely used. During the production process, a liquid electrically controlled discharge valve is required when discharging the material.

[0003] Existing technologies have certain shortcomings for electrically controlled discharge valves. For example, traditional sealing materials such as rubber and ordinary stainless steel are easily oxidized and corroded by hydrogen peroxide, which may lead to valve leakage and shorten the life of the electrically controlled discharge valve. In addition, hydrogen peroxide crystallization or decomposition residues will accumulate on the valve core surface, affecting the switching accuracy and even causing leakage. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a liquid electronically controlled discharge valve for hydrogen peroxide production, which has the advantages of corrosion resistance, swirling anti-deposition, and removal of adhering substances, thus solving the problems mentioned in the background art.

[0005] This utility model provides the following technical solution: a liquid electrically controlled discharge valve for hydrogen peroxide production, comprising a valve body, a valve cavity at the top of the valve body, an inlet and an outlet at the two sides of the valve body respectively, threaded grooves at the openings of the inlet and outlet, a threaded plate fixedly installed inside the inlet on one side of the threaded groove, a flow groove between the valve cavity and the inlet, the valve cavity and the outlet being connected, a flange A at the opening of the valve cavity at the top of the valve body, a valve cover fixedly installed at the top of the valve body, and an electromagnetic device sleeved on the outer ring of the valve cover.

[0006] With the above structural design, this device can achieve corrosion prevention, swirling anti-deposition, and removal of adhering substances in practical applications. By setting the materials of the top block and valve core, a stable passivation film is formed between the top block and valve core in a strong oxygen environment. By setting the threaded plate, the liquid initially entering the feed inlet is forced to change its flow direction to form a swirling flow. By setting the piezoelectric ceramic vibrator, high-frequency mechanical vibration is generated after being energized, which drives the sealing gasket and valve core to vibrate.

[0007] Preferably, the valve cover includes a flange B, which is adapted to the shape of flange A. The valve cover has a sliding groove inside, and a moving iron core is slidably installed inside the sliding groove. The moving iron core is an iron block, and a spring A is fixedly connected between the moving iron core and the top wall of the sliding groove. A top block is provided at the bottom of the moving iron core, and a piezoelectric ceramic vibrator is movably sleeved above the top block at the lower end of the moving iron core. The vibration frequency of the piezoelectric ceramic vibrator is 20KHz.

[0008] Through the above structural design, the materials of the top block and valve core are selected so that a stable passivation film is formed in the hydrogen peroxide, preventing further corrosion by the hydrogen peroxide and extending the service life of the top block and valve core. The hardness reaches HRA888 Rockwell hardness to ensure no wear and deformation during long-term use.

[0009] Preferably, a spring B is fixedly connected between the top of the piezoelectric ceramic oscillator and the bottom wall of the upper end of the moving iron core. A valve core is fixedly sleeved between the top block and the piezoelectric ceramic oscillator on the outer ring of the lower end of the moving iron core. The top block and the valve core are made of zirconium oxide ceramic. The surface of the top block is laser-coated with tungsten carbide. A sealing gasket is fixedly sleeved on the outer ring of the lower end of the moving iron core. The sealing gasket is adapted to the shape of the flange A. The sealing gasket is located between the valve core and the piezoelectric ceramic oscillator. A fixing head is fixedly installed on the top of the valve cover. The top of the fixing head is provided with a threaded post.

[0010] With the above structural setup, the piezoelectric ceramic vibrator is in contact with the sealing gasket. When the piezoelectric ceramic vibrator is energized, it generates a high-frequency mechanical vibration of 20KHz, which simultaneously drives the sealing gasket and valve core to vibrate together. The cavitation effect generated by the vibration breaks down the deposits attached to the surface of the valve core and sealing gasket, achieving thorough cleaning.

[0011] Preferably, the electromagnetic device is slidably sleeved on the outer ring of the valve cover, the electromagnetic device is provided with an electromagnetic coil inside, the top of the electromagnetic device is provided with a mounting cap, the mounting cap is threadedly installed on the outer ring of the threaded column, the inner ring of the mounting cap is threaded and is threadedly adapted to the threaded column.

[0012] With the above structural design, the position of the electromagnetic device is fixed by matching the mounting cap with the fixing head, and the electromagnetic device can be quickly removed by removing the mounting cap.

[0013] This utility model has the following advantages:

[0014] 1. This liquid electro-controlled discharge valve for hydrogen peroxide production achieves self-cleaning and anti-scaling through a structure including threaded plates, piezoelectric ceramic vibrators, and valve cores. When the liquid initially enters the inlet, it first passes through the threaded plates, causing the liquid to spiral and generate centrifugal force, preventing impurities and crystalline particles in the liquid from adhering to the inside of the valve body. After the liquid reaches the valve cavity and the outlet, the threaded plates disappear, and a slow turbulent flow is generated, allowing internal impurities to be discharged with the liquid. By supplying power to the piezoelectric ceramic vibrator, a 20kHz high-frequency mechanical vibration is generated, which breaks up the deposits adhering to the valve core and sealing gasket surface through cavitation effect, achieving the effect of self-cleaning and anti-scaling.

[0015] 2. This liquid electronically controlled discharge valve for hydrogen peroxide production achieves oxidation resistance through the design of a top block and valve core. The materials used for the top block and valve core allow them to form a stable passivation film in the hydrogen peroxide, preventing further hydrogen peroxide corrosion and extending the service life of the top block and valve core. The hardness reaches HRA888 Rockwell hardness, ensuring no wear or deformation during long-term use. Due to the materials of the valve core and top block, liquid corrosion is greatly reduced, achieving an anti-oxidation effect. Attached Figure Description

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.

[0021] Please see Figures 1-2A liquid electrically controlled discharge valve for hydrogen peroxide production includes a valve body 1, a valve cavity 11 at the top of the valve body 1, an inlet 12 and an outlet 13 on both sides of the valve body 1, threaded grooves 14 at the openings of the inlet 12 and the outlet 13, a threaded plate 15 fixedly installed inside the inlet 12 on one side of the threaded groove 14, a flow groove between the valve cavity 11 and the inlet 12, and the valve cavity 11 and the outlet 13 are connected, a flange A16 is provided at the opening of the valve cavity 11 at the top of the valve body 1, a valve cover 2 is fixedly installed at the top of the valve body 1, and an electromagnetic device 3 is sleeved on the outer ring of the valve cover 2.

[0022] In practical applications, this device can provide corrosion protection, swirling flow to prevent sedimentation, and removal of adhering substances. By adjusting the materials of the top block 23 and the valve core 26, a stable passivation film is formed between them in a strong oxygen environment, preventing further corrosion by hydrogen peroxide. By setting the threaded plate 15, the liquid initially entering the feed inlet 12 is forced to change its flow direction, forming a swirling flow to prevent impurities and crystalline particles from depositing inside the valve body 1. By setting the piezoelectric ceramic vibrator 24, high-frequency mechanical vibration is generated after being energized, which drives the sealing gasket 27 and the valve core 26 to vibrate, breaking up the adhering substances through cavitation effect.

[0023] Please see Figures 1-3 The valve cover 2 includes a flange B, which is compatible with the shape of the flange A16. The flange B and the flange A16 are fixedly installed by bolts. The valve cover 2 has a sliding groove inside, and a moving iron core 21 is slidably installed inside the sliding groove. The moving iron core 21 is an iron block and can be moved by magnetic force. A spring A22 is fixedly connected between the moving iron core 21 and the top wall of the sliding groove. A top block 23 is provided at the bottom of the moving iron core 21.

[0024] The materials of the top block 23 and the valve core 26 are designed so that the top block 23 and the valve core 26 form a stable passivation film in the hydrogen peroxide, preventing further corrosion by the hydrogen peroxide and extending the service life of the top block 23 and the valve core 26. The hardness reaches HRA888 Rockwell hardness to ensure no wear and deformation during long-term use.

[0025] Please see Figures 1-3A piezoelectric ceramic vibrator 24 is movably sleeved on the lower outer ring of the moving iron core 21 above the top block 23. The piezoelectric ceramic vibrator 24 has a vibration frequency of 20KHz. A spring B25 is fixedly connected between the top of the piezoelectric ceramic vibrator 24 and the bottom wall of the upper end of the moving iron core 21. A valve core 26 is fixedly sleeved on the lower outer ring of the moving iron core 21 between the top block 23 and the piezoelectric ceramic vibrator 24. The top block 23 and the valve core 26 are made of zirconia ceramic, which is resistant to hydrogen peroxide corrosion. The surface of the top block 23 is laser-coated with tungsten carbide to resist the erosion of hydrogen peroxide crystal particles. A sealing gasket 27 is fixedly sleeved on the lower outer ring of the moving iron core 21. The sealing gasket 27 is adapted to the shape of the flange A16. The sealing gasket 27 is located between the valve core 26 and the piezoelectric ceramic vibrator 24. A fixing head 28 is fixedly installed on the top of the valve cover 2. The fixing head 28 has a threaded post on the top.

[0026] By setting the piezoelectric ceramic vibrator 24 to contact the sealing gasket 27, the piezoelectric ceramic vibrator 24 generates a high-frequency mechanical vibration of 20KHz after being energized. At the same time, it drives the sealing gasket 27 and the valve core 26 to vibrate together. The cavitation effect generated by the vibration breaks down the deposits attached to the surface of the valve core 26 and the sealing gasket 27, achieving thorough cleaning.

[0027] Please see Figures 1-3 The electromagnetic device 3 is slidably sleeved on the outer ring of the valve cover 2. The electromagnetic device 3 is equipped with an electromagnetic coil inside. When energized, it can make the moving iron core 21 move upward. The top of the electromagnetic device 3 is equipped with a mounting cap 31. The mounting cap 31 is threadedly installed on the outer ring of the threaded column. The inner ring of the mounting cap 31 is threaded and is threaded to match the threaded column.

[0028] When the electromagnetic device 3 is energized, it can drive the moving iron core 21 to slide inside the valve cover 2 to achieve the open state. The position of the electromagnetic device 3 is fixed by matching the mounting cap 31 with the fixing head 28. The electromagnetic device 3 can be quickly removed by removing the mounting cap 31.

[0029] Working principle: The inlet 12 is connected to the discharge pipe via a threaded connection, making the connection between the valve body 1 and the discharge pipe more stable. Under normal conditions, the valve core 26 and the sealing gasket 27 are pressed against the middle of the valve cavity 11, preventing communication between the inlet 12 and the outlet 13. When opening is required, power is supplied to the electromagnetic device 3. The electromagnetic coil inside the device 3 generates magnetic force, driving the moving iron core 21 upward. As the moving iron core 21 moves upward, it also drives the top block 23 and the sealing gasket 27 upward, so that the valve core 26 and the sealing gasket 27 are no longer pressed against the middle of the valve cavity 11. This allows the liquid inside the inlet 12 to flow through the valve cavity 11 and into the outlet 13. When the liquid initially enters the inlet 12, it first passes through the threaded plate 15, causing the liquid to spiral, creating friction between the liquid particles. Centrifugal force prevents impurities and crystalline particles in the liquid from adhering to the inside of the valve body 1. After the liquid reaches the valve cavity 11 and the outlet 13, due to the disappearance of the threaded plate 15, a slow turbulent flow will be generated, and the internal impurities will be discharged with the liquid. Due to the material of the valve core 26 and the top block 23, the corrosion of the liquid is greatly reduced, extending the life of the top block 23 and the valve core 26. When this device is used for a long time, impurities and crystalline particles inside the liquid will adhere to the surface of the valve core 26 and the sealing gasket 27. After the electromagnetic device 3 is de-energized, a gap is created in the sealing state of the middle of the valve cavity 11. By supplying power to the piezoelectric ceramic vibrator 24, a 20KHz high-frequency mechanical vibration is generated, which breaks the deposits on the surface of the valve core 26 and the sealing gasket 27 through the cavitation effect, achieving a self-cleaning effect inside the valve body 1.
