Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic coating equipment, in particular to a self-locking transmission valve with an externally arranged valve plate for photovoltaic coating equipment and capable of rotating movement. Background Art

[0002] Photovoltaic coating refers to coating a special film layer on the surface of photovoltaic cells. The main purpose is to improve the photoelectric conversion efficiency of photovoltaic cells, reduce light reflection, increase light capture, and prevent reflection. When using photovoltaic coating equipment, a transmission valve is required to control the opening and closing of the pipeline outlet.

[0003] For example, the utility model with application number CN202320382444.0 discloses a corrosion-resistant soft-sealed butterfly valve. The utility model uses the elastic force of the first spring to allow the sealing block to enter the sealing groove when the valve disc is in a closed state, and the valve disc is sealed by the cooperation of the sealing block and the sealing groove on the valve disc. The spring elastic force pushes the sealing gasket to fit tightly with the valve disc, and the sealing effect is better. The sealing gasket goes deep into the inside of the valve disc, and a little wear on the edge will not affect the sealing effect. The sealing block can limit the valve disc so that the valve disc will not move at will when closed, thereby improving the stability of the valve disc. The surface of the metal sealing block can be provided with an anti-corrosion layer to prevent the sealing structure from being corroded, thereby improving the service life of the soft-sealed butterfly valve. However, in the actual use of such valves, the valve plate is usually located inside the valve. When the valve plate needs to be maintained and repaired, the entire valve body needs to be disassembled before the internal valve plate can be maintained and repaired, resulting in the problem of extending the downtime of the photovoltaic coating equipment.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a self-locking transmission valve with an external valve plate and rotating motion is provided for photovoltaic coating equipment. Utility Model Content

During operation, the restriction between the limit ring and the fixing ear can be quickly released by pulling hard and removing the latch. At this time, the valve stem can be rotated to control the opening and closing of the valve. At the same time, since the size of the active gear is smaller than that of the driven gear, it is more labor-saving when adjusting. After adjustment, the limit ring and the fixing ear are connected by the latch through the limit hole and the locking hole, which can limit the rotation of the hand wheel, making the valve body more stable after adjustment. In addition, the magnet can adsorb the iron limit ring to prevent the latch from falling off. BRIEF DESCRIPTION OF THE DRAWINGS
