[0002] The polished rod valve bracket is mainly used for supporting and supporting the valve body during maintenance. The currently used polished rod valve bracket is mainly composed of an upper plate, a lower plate and a connecting rod, but the three are of an integrated structure, and the material is steel. When the structure is relatively large and the steel material is relatively heavy, it is inconvenient to carry. When the detachable structure is adopted, due to the influence of the connection rod between the upper plate and the lower plate as a whole and the positioning accuracy, the upper plate has a slight inclination relative to the horizontal plane. situation happened

The invention discloses a polished rod valve bracket, which is characterized by mainly comprising an upper disc, a lower disc and two symmetrically arranged connecting rods, wherein the connecting rods consist of upper and lower connecting rods; the upper ends of the upper connecting rods are arranged in upper disc positioning holes; the lower ends of the lower connecting rods are arranged in lower disc positioning holes; and the lower ends of the upper connecting rods are embedded in upper ends of the lower connecting rods, or the upper ends of the lower connecting rods are embedded in lower ends of the upper connecting rods, and the matching parts of the upper connecting rods and the lower connecting rods are in threaded connection. By designing the connecting rods between the upper disc and the lower disc in the form of the upper connecting rods and the lower connecting rods and adopting the threaded connection between the upper connecting rods and the lower connecting rods, the upper disc can be micro-adjusted by only adjusting the matching length for threaded connection of the upper connecting rods and the lower connecting rods.
Description
technical field [0001] The invention relates to a polished rod valve bracket, in particular to a polished rod valve bracket whose upper plate can be finely adjusted in level. Background technique [0002] The polished rod valve bracket is mainly used for supporting and supporting the valve body during maintenance. The currently used polished rod valve bracket is mainly composed of an upper plate, a lower plate and a connecting rod, but the three are of an integrated structure, and the material is steel. When the structure is relatively large and the steel material is relatively heavy, it is inconvenient to carry. When the detachable structure is adopted, due to the influence of the connection rod between the upper plate and the lower plate as a whole and the positioning accuracy, the upper plate has a slight inclination relative to the horizontal plane. Situation happens. Contents of the invention [0003] The technical problem to be solved by the present invention is to ...
