Embodiment 1

[0042] This embodiment provides a large-scale valve cleaning production line, comprising:

[0043] carrying device, such as figure 1 As shown, the bottom is hollowed out to carry and fix the valve;

[0044] The cleaning device sequentially includes a first immersion device for rinsing the valve with cleaning liquid, a spray rinsing device for rinsing the valve in six mutually perpendicular directions with cleaning liquid, and a cleaning device for rinsing the valve with clean water. The second rinsing device for rinsing the valve, the air heating drying device for spraying hot air on the valve to dry the valve, the spraying and rinsing device includes a bottom cleaning device, an upper cleaning device, a front cleaning device, and a rear cleaning device. device, left cleaning device and right cleaning device, each cleaning device has several water outlets;

[0045] transmission devices such as figure 2 As shown, four toothed chain conveyor belts set independently of each o...

Embodiment 2

[0074] This embodiment provides a large-scale valve cleaning method, adopting the large-scale valve production line described in Embodiment 1, comprising the following steps,

[0075] S1: Use the cleaning solution to soak the valve. In this step, use the paddle to stir the cleaning solution. The rotation speed of the paddle is 100-150r / min, such as 100r / min, 120r / min, 150r / min, etc. The rotation time of the paddle is 40-50min, such as 40min, 45min, 50min, etc. After using the paddle to stir the cleaning liquid, it also includes the process of cleaning the valve with ultrasonic waves. The ultrasonic frequency is 28kHz-35kHz, such as 28kHz, 30kHz, 35kHz etc., the power is 2-2.5w / cm 2 , such as 2w / cm2 , 2.2w / cm 2 , 2.5w / cm 2 etc., ultrasonic cleaning time is 20-40min, such as 20min, 30min, 40min, etc.;

[0076] S2: Use cleaning liquid to flush the valve in six mutually perpendicular directions. In this step, the spray speed of cleaning liquid is 30-40m / s, such as 30m / s, 35m / s,...

Abstract

The invention discloses a large valve cleaning production line and a cleaning method. A valve is fixed by a bearing device, and is conveniently transported; a transmission device and a pushing-extracting device achieve effects of transmission and guide, so that the bearing device along with the valve passes through a first soaking device, a spraying flushing device, a second soaking device and an air-heating drying device in sequence, so that automatic cleaning of the valve is realized. Besides, the first soaking device can be used for soaking the valve by use of a cleanout fluid; the spraying flushing device can flush the valve in six directions which are perpendicular to one another by use of the cleanout fluid; the second soaking device is used for soaking the valve by use of clear water to remove the cleanout fluid; and finally, the clear water is evaporated by virtue of the air-heating drying device, so that the valve is dried to prevent corrosion; and a control device realizes automatic operation of the actions. The large valve cleaning production line is good in cleaning effect and is high in cleaning efficiency while used for cleaning the valve.

Description

technical field [0001] The invention relates to a large-scale valve cleaning production line, which belongs to the technical field of valve manufacturing equipment. Background technique [0002] On natural gas, oil and other energy transmission pipelines, the diameter of the pipeline is usually more than 500mm, and in order to make the natural gas and oil flow smoothly in the pipeline, it is necessary to exert a large pressure in the pipeline, which makes the large valves installed on the energy pipeline The size is huge, the quality is heavy, and the quality reaches more than 20kg, and some even exceed 50kg. [0003] During the manufacturing process of the above-mentioned large valves and after the assembly is completed, the valves need to be cleaned. For example, when the valve core is installed in the valve cavity, it is necessary to clean the valve core and the valve cavity to ensure the tightness after assembly. After the valve is assembled, it must be cleaned to remo...
