Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of valve fouling cleaning, and particularly relates to a valve fouling cleaning device. BACKGROUND

[0002] Valves are devices that make the medium (liquid, gas, powder) in the pipeline and equipment flow or stop and can control the flow. Valves can be used to control the flow of air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media, etc. Valves are control components in fluid conveying systems, which are used to change the cross section and flow direction of the medium, and have the functions of flow guiding, stopping, throttling, check, splitting or overflow pressure relief. Valves for fluid control, from the simplest stop valve to the most complex self-control system used in various valves, have various types and specifications, and the nominal diameter of the valve ranges from extremely small instrument valves to industrial pipeline valves with a diameter of up to 10 m. Valves can be used to control the flow of water, steam, oil, gas, mud, various corrosive media, liquid metal and radioactive fluids.

[0003] Due to the presence of various impurities in the liquid, a large amount of fouling is easily produced in the equipment, pipeline and valve. These fouling causes the valve to be unable to open or causes the valve to have a reduced conduction capacity. Therefore, only a new valve can be replaced. For some inexpensive valves, the replaced valve is usually directly discarded. For some expensive valves, the replaced valve needs to be cleaned and then used again.

[0004] In the current market environment, there are indeed some mechanical devices specially used for valve cleaning. However, these devices have obvious limitations in actual application, and they can only clean some specific positions of the valve and cannot comprehensively cover all corners of the valve. Therefore, the cleaning effect is not satisfactory, and it is difficult to achieve the expected cleaning standard, which cannot effectively guarantee the maintenance and maintenance of the valve.

[0051] In use of the valve dirt cleaning device, first, the valve to be cleaned is placed on the support plate 129, the support rod 106 is adjusted to be in the position below the valve hand wheel, and the valve hand wheel is not in contact with the support rod 106. Then the first cleaning assembly is started, the first cylinder 118 on the mounting block 102 drives the piston rod to extend, thereby driving the first motor 119 and the connecting disc to approach the valve. After the first cleaning rod 121 is inserted into the valve body, the electromagnet is powered to attract the first sliding block 123 to move, so as to ensure that the first brush 122 is in contact with the inner wall of the valve body. Since the first cleaning rod 121 is eccentrically connected to the connecting disc, when the first motor 119 is started, the connecting disc drives the first cleaning rod 121 to rotate, and the plurality of first brushes 122 on the first cleaning rod 121 can clean the inside of the valve comprehensively and efficiently.

[0052] At the same time, when the valve body is placed on the support plate 129, the transmission rod 107 is pushed into the box body 101, and the rotating roller is driven to rotate by the transmission rod 107. The flange on the rotating roller is gradually pushed to the valve side wall by the characteristic that the arc surface gradually increases. The plurality of second brushes 105 on the first movable plate 104 are in full contact with the valve side wall, and can clean the valve side wall in detail when the valve moves up and down. The movable rod 138 in the telescopic rod slides in the sleeve 137, and the second spring 139 plays a buffering and resetting role, so as to ensure that the first movable plate 104 can move stably and flexibly.

[0053] When the inside of the valve body is cleaned, the second cylinder 111 of the mounting frame 110 on the side plate 109 is started, the piston rod of the second cylinder 111 pushes the second push rod 112, and the second push rod 112 is abutted on the support plate 129, so that the support plate 129 is lowered. After the support plate 129 is lowered, the third cleaning assembly starts to work. The second motor 144 is started, the cam 114 on the output shaft of the second motor 144 is rotated, and the third push rod 113 is pushed to slide on the second push rod 112. The third push rod 113 passes through the first through slot on the support plate 129 and acts on the second movable plate 145 below. The transmission plate 147 on the second movable plate 145 is in transmission cooperation with the connecting shaft 146 on the second cleaning rod 116, so as to drive a plurality of second cleaning rods 116 to rotate, and the plurality of third brushes 128 on the second cleaning rod 116 can clean the bottom of the valve body. The fifth spring 149 is abutted on the lug plate 148 of the connecting plate 115, so as to ensure stable operation of the second movable plate 145.

[0054] At this time, the first cleaning rod 121 is in the position of the top of the valve body, the first motor 119 drives the first cleaning rod 121 to rotate, and the first brush 122 cleans the top of the valve body.

[0055] During the whole cleaning process, the ultrasonic generator in the cleaning tank continuously works to generate ultrasonic waves in the cleaning tank. The high-frequency vibration of the ultrasonic waves can further clean the valve body in the cleaning tank in a deep level, so that the dirt attached to each part of the valve is more easily removed under the action of the ultrasonic waves, thereby greatly improving the cleaning effect. Through the cooperative work of the first cleaning assembly, the second cleaning assembly, the third cleaning assembly and the ultrasonic generator, the valve dirt cleaning device can reduce the cleaning dead angle and comprehensively and efficiently complete the cleaning task of the valve.
