CN-121993624-A - Valve plate disengaging structure of fan-shaped glasses valve

Abstract

The invention provides a fan-shaped eyeglass valve plate disengaging structure which comprises a left valve body, a valve plate and a screw rod, wherein two ejector rod mechanisms are arranged on the left valve body, a base plate is arranged on one side, close to the left valve body, of a guide rail of the valve plate, and a clamping ring is arranged on the screw rod on the other side of the valve plate. The ejector rod mechanism, the base plate and the clamping ring are utilized to forcedly separate the valve plate when the valve plate acts, and the ejector rod mechanism and the clamping ring form limit to the valve plate so as to prevent the valve plate from shaking left and right, thereby playing a role in protecting the rubber sealing ring.

Description

Valve plate disengaging structure of fan-shaped glasses valve Technical Field The invention relates to the technical field of fan-shaped eyeglass valves. Background In the actual use process of the existing fan-shaped eyeglass valve, as the separation distance between the valve plate and the sealing surface of the valve seat is small, the valve seats of the left valve body and the right valve body are scratched and the rubber sealing rings are scratched in the switching process of the blind through plates of the valve plate, so that leakage is caused. Disclosure of Invention The invention provides a fan-shaped eyeglass valve plate disengaging structure, which comprises a left valve body, a valve plate and a screw rod, wherein two ejector rod mechanisms are arranged on the left valve body, a base plate is arranged on one side, close to the left valve body, of a guide rail of the valve plate, the base plate is three base plates with different sizes, the base plate is fixed with the valve plate in a welding mode, and a clamping ring is arranged on the screw rod on the other side of the valve plate. Preferably, the ejector rod mechanism comprises an ejector rod, a roller and a pin shaft. Advantageous effects The ejector rod mechanism, the base plate and the clamping ring are utilized to forcedly separate the valve plate when the valve plate acts, and the ejector rod mechanism and the clamping ring form limit to the valve plate so as to prevent the valve plate from shaking left and right, thereby playing a role in protecting the rubber sealing ring. Drawings FIG. 1 is a schematic view of a valve plate disengaging structure; Fig. 2 is a schematic view of a valve structure of a fan-shaped glasses. In the figure, the valve comprises a push rod mechanism 1, a left valve body 2, a base plate 3, a valve plate 4, a valve seat 5, a clamping ring 6, a screw rod 7 and a rubber sealing ring 8. Detailed Description The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention. Referring to fig. 1-2, two ejector rod mechanisms are firstly arranged on a left valve body, then three base plates with different lengths are welded on one side of a valve plate guide rail, which is close to the left valve body, the base plates are matched with the ejector rod mechanisms for use, and then a clamping ring is arranged on a screw rod on the other side of the valve plate. When the valve is fully opened or fully closed, the ejector rod is positioned in a gap between the base plates, when the valve plate moves, the ejector rod structure is matched with the base plates, so that the valve plate is forcedly separated from the sealing surface of the valve seat, meanwhile, the other side of the valve plate is matched with the clamping ring, and the valve plate is prevented from shaking left and right in the moving process under the double functions of the ejector rod and the clamping ring, so that the protection of the rubber sealing ring is realized. The valve body is integrated, and the valve body and the pipeline are connected in a butt welding mode, so that the phenomenon that the medium leaks from the gasket due to flange connection can be avoided. It is noted that relational terms such as first and second, and the like are used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions.
