DETAILED DESCRIPTION

[0021] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] Please refer to the attached Figure 1 -Attached Figure 3The embodiment of the present invention provides a piston valve body cleanliness detection device, including a shell 1, a switch door 2 is provided on the inner wall of the shell 1, a water tank 3 is fixedly connected to the upper surface of the shell 1, a nozzle 4 is provided on the outer wall of the water tank 3, the outer wall of the nozzle 4 is fixedly connected to the inside of both sides of the shell 1, a fan 5 is fixedly connected to the inside of the upper side of the shell 1, a detection component is provided on the upper surface of the shell 1, a fixing plate 1 6 and a fixing plate 2 7 are fixedly connected to the inside of the lower side of the shell 1, an electric push rod 8 is fixedly connected to the inner bottom wall of the shell 1, the output end of the electric push rod 8 is connected to a connecting column 9, a motor 10 is fixedly connected to the inside of the connecting column 9, and the output end of the motor 10 is connected to a support platform 11.

[0023] Specifically, the piston valve body is fixed on the upper surface of the support platform 11, and a water pump is provided inside the water tank 3. The water pump draws water and sprays it from the nozzle 4 to clean the piston valve body. When the cleaning is completed, the electric push rod 8 is started again, and the electric push rod 8 will drive the connecting column 9 to descend. The interior of the shell 1 is provided with an ultrasonic cleaning device, and the ultrasonic cleaning device is located between the fixing plate 1 6 and the fixing plate 2 7, and then the ultrasonic wave will clean the piston valve body. When the cleaning is completed, the electric push rod 8 is started to rise, and the electric push rod 8 will drive the connecting column 9 to rise. The rise of the connecting column 9 will drive the support platform 11 and the piston valve body to rise, and then the fan 5 is started to air-dry the piston valve body, and then the motor 10 is started. The motor 10 is a waterproof motor. The motor 10 will drive the support platform 11 and the piston valve body to rotate, so as to change the posture of the valve body and eliminate the shielding phenomenon, so that the detection equipment can directly detect the shielded part, thereby obtaining more accurate cleanliness information.

[0024] Finally, the piston valve body is scanned by the detection head 13 for detection, thereby reducing the transfer of the valve body between different devices, avoiding secondary contamination, and improving the accuracy of the detection results. The cleaning method combined with high-pressure spraying and ultrasonic cleaning can thoroughly clean the valve body. The valve body does not need to be taken out after cleaning, and can directly enter the detection area in the same device for cleanliness detection, which simplifies the detection process and improves work efficiency.

[0025] Please refer to the attached Figure 2 The detection component includes a detector 12, the lower surface of the detector 12 is fixedly connected to the upper surface of the shell 1, the outer wall of the detector 12 is fixedly connected to a detection head 13, and the outer wall of the detection head 13 is fixedly connected to the upper inner wall of the shell 1.

[0026] Specifically, the detector 12 and the detection head 13 are infrared spectrometers, which can analyze organic impurities. Organic compounds with different structures have unique infrared absorption spectra, which can be used to identify and analyze the composition and content of organic pollutants remaining on the surface of the valve body to determine whether the cleaning effect meets the requirements.

[0027] Please refer to the attached Figure 3 and attached Figure 4 The upper outer wall of the connecting column 9 is fixedly connected to the limiting plate 15, and the lower outer wall of the connecting column 9 is fixedly connected to the limiting plate 14. The upper surface of the limiting plate 15 is arranged at the bottom end of the fixed plate 6, and the lower surface of the limiting plate 14 is arranged at the bottom end of the fixed plate 7.

[0028] Specifically, the connecting column 9 is used to fix the limiting plate 2 15 and the limiting plate 1 14. The limiting plate 1 14 and the limiting plate 2 15 cooperate with each other to limit the descending and ascending height of the connecting column 9. At the same time, the existence of the limiting plate 2 15 and the limiting plate 1 14 can better prevent water leakage.

[0029] Please refer to the attached Figure 2 and attached Figure 3 The shape of the fixing plate 1 6 is an equilateral triangle, and ultrasonic cleaning is used between the fixing plate 1 6 and the fixing plate 2 7 .

[0030] Specifically, the design of the fixed plate 6 as an equilateral triangle has many advantages. First, this shape can make the water stains on the upper surface of the fixed plate 6 flow out of the water outlet more smoothly after cleaning. The three sides of the equilateral triangle are equal in length. Its unique geometric structure enables the water stains to flow quickly and evenly to the water outlet along the inclined plate surface under the action of gravity, effectively avoiding the residual water stains. The fixed plate 6 can rely on its stable structure to ensure the smooth operation of the entire device, reduce shaking and vibration, and thus ensure the accuracy and reliability of cleaning and detection work.

[0031] The principle of ultrasonic cleaning is to generate high-frequency vibration signals through an ultrasonic generator, convert them into high-frequency mechanical vibrations and transmit them to the cleaning fluid, causing the cleaning fluid to produce countless tiny bubbles. When these bubbles come into contact with the surface of the piston valve body, they will burst instantly, generating a strong impact force, peeling off the dirt and impurities on the valve body surface and internal gaps and holes.

[0032] Please refer to the attached Figure 2 and attached Figure 3 A water outlet is opened inside the shell 1, and the water outlet is arranged on the upper side of the fixing plate 1 6. A water outlet and a water inlet are opened inside the shell 1, and the water outlet and the water inlet are arranged between the fixing plate 1 6 and the fixing plate 2 7.

[0033] Specifically, the water outlet located on the upper side of the fixed plate 6 plays a vital role in the operation of the equipment. When the nozzle 4 cleans the piston valve body, a large amount of water will be sprayed onto the fixed plate 6. This water outlet can discharge the cleaning water in time to avoid excessive accumulation of water inside the equipment. The water outlet and water inlet are arranged between the fixed plate 6 and the fixed plate 2 7. During ultrasonic cleaning, the cleaning liquid needs to circulate continuously in this area. The water inlet is responsible for introducing the filtered and formulated cleaning liquid into the area to ensure an adequate supply of cleaning liquid to maintain a stable cleaning environment.

[0034] Please refer to the attached Figure 4 and attached Figure 5 The outer wall of the connecting column 9 is provided with a rubber ring to prevent water leakage, and the rubber ring is located between the limiting plate 14 and the limiting plate 2 15.

[0035] Specifically, the connecting column 9 moves up and down frequently during the operation of the equipment. When the piston valve body is cleaned and the ultrasonic cleaning is performed, a large amount of water will exist inside the equipment. If the sealing between the connecting column 9 and the surrounding structure is not good, water will easily leak. The setting of the rubber ring is like a solid barrier, which fits tightly against the outer wall of the connecting column 9 and effectively prevents water leakage. The limit plate 1 14 and the limit plate 2 15 can ensure that the rubber ring is always in the appropriate position and will not be offset or fall off due to the movement of the connecting column 9, thereby continuously playing a good sealing role.

[0036] Please refer to the attached Figure 6 -Attached Figure 8 The right upper surface of the support platform 11 is fixedly connected to a base plate 16, the right upper surface of the base plate 16 is fixedly connected to a fixed platform 17, the outer wall of the fixed platform 17 is slidably connected to a sliding platform 18, and the upper surface of the sliding platform 18 is fixedly connected to a clamping plate 19; the left upper surface of the base plate 16 is fixedly connected to a fixed platform 20, the outer wall of the fixed platform 20 is slidably connected to a sliding platform 21, and the upper surface of the sliding platform 21 is fixedly connected to a clamping plate 22.

[0037] Specifically, the bottom plate 16 is used to support the fixed platform 17 and the fixed platform 20, the fixed platform 17 is used to support the sliding platform 18 to slide on its outer wall, and the fixed platform 20 is used to support the sliding platform 21 to slide on its outer wall, and the clamping plate 22 and the clamping plate 19 cooperate with each other to fix the piston valve body.

[0038] Please refer to the attached Figure 6 -Attached Figure 8A motor 23 is fixedly connected to the upper surface of the middle part of the bottom plate 16, and a gear 24 is connected to the output end of the motor 23. A rack 25 is meshedly connected to the tooth end of one side of the gear 24, and a rack 26 is meshedly connected to the tooth end of the other side of the gear 24; the lower surface of the rack 25 is fixedly connected to the upper surface of the sliding table 18, and the lower surface of the rack 26 is fixedly connected to the upper surface of the sliding table 21.

[0039] Specifically, the motor 23 is used to drive the gear 24 to rotate. The rotation of the gear 24 will drive the rack 26 and the rack 1 25 at the tooth end to slide. The sliding of the rack 26 and the rack 1 25 is used to drive the sliding table 18 to slide on the outer wall of the fixed table 17, and at the same time drive the sliding table 21 to slide on the outer wall of the fixed table 20, thereby meeting the diverse needs of different customers. There is no need to purchase separate testing equipment for each size of piston valve body, which reduces equipment procurement costs and management costs and enhances the company's market competitiveness.
