Clamping groove type anti-rotation ejection rod mechanism for glasses valve

Abstract

Provided is a clamping groove type anti-rotation ejection rod mechanism for a glasses valve. The clamping groove type anti-rotation ejection rod mechanism comprises an ejection rod. A rolling wheel is installed at one end of the ejection rod and connected with the ejection rod through a pin shaft. The other end of the ejection rod is sleeved with a shaft base which penetrates through a valve body and is fixedly connected with a cover plate. A groove is formed in the end, sleeved with the shaft base, of the ejection rod. The cover plate is provided with a protrusion which is clamped in the groove. The clamping groove type anti-rotation ejection rod mechanism for the glasses valve has the beneficial effects that the circumferential freedom degree of the ejection rod is limited through the mechanism so that the situation that the ejection rod rotates due to the impact on the ejection rod when a valve plate moves axially can be prevented, the effect that the valve plate always moves in the position limited through the rolling wheel during movement is ensured, and the movement stability of the valve is ensured.

Description

Technical field [0001] The invention relates to a push rod mechanism, in particular to a push rod mechanism with an anti-rotation function applied to a spectacle valve. Background technique [0002] In the existing spectacle valve, the ejector rod in the ejector rod mechanism is easy to rotate during the movement of the valve plate, causing the rolling friction between the roller and the valve seat to change into sliding friction, which cannot guarantee the stability of the valve plate movement. The friction between the valve plate and the valve seat is damaged, which affects the sealing performance of the valve. Contents of the invention [0003] In order to overcome the above-mentioned shortcomings of the existing ejector mechanism, the present invention provides an ejector mechanism with anti-rotation function. [0004] The technical solution adopted by the present invention to solve the technical problem is that a slot-type anti-rotation ejector rod mechanism of a spe...
