Abstract

The invention relates to the field of valves, in particular to a V-shaped ball valve structure. The valve-shaped ball valve structure comprises a valve body, a valve core and a valve seat. The V-shaped ball valve structure is characterized in that a cavity is formed in the valve body; the top of the valve body is connected with a bracket; a lower valve rod is embedded into the middle of the bottom of the valve body; the bottom of the lower valve rod is embedded into the valve body; the top end of the lower valve rod is exposed in the cavity; the valve core is arranged in the cavity in the upper surface of the lower valve rod; the valve seat is arranged in the cavity at the left side of the valve core; the lower surface of the valve core is fixed on the lower valve rod; an upper valve rod is arranged on the upper surface of the valve core; the upper valve rod is embedded into the top of the valve body; and the top of the upper valve rod penetrates out of the valve rod and is connected with the lower surface of the top of the bracket. In comparison with the prior art, the V-shaped ball valve has a regulating valve cut-off function, can realize proportional regulation and switching type regulation of the valve by virtue of different accessories, and is especially suitable for media such as cellulosic thick paper pulp and the like; and by virtue of a quick type valve rod structure, on-site maintenance and repair are more convenient.

Description

technical field [0001] The invention relates to the field of valves, in particular to a V-shaped ball valve structure. Background technique [0002] The V-shaped ball valve is a fixed ball valve and a single-seat sealed ball valve, and its regulating performance is the best among ball valves. Due to the shearing effect between the V-shaped notch of the V-shaped ball valve and the metal valve seat, and the opening and closing quickly, lightly, with small fluid resistance and good sealing performance, the V-shaped ball valve is often used to control fibers and tiny solid particles. , slurry and other media. However, the existing V-shaped ball valve also has the disadvantages of being inconvenient for on-site maintenance and maintenance, and unable to realize valve proportional adjustment and on-off adjustment. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the present invention designs a V-shaped ball valve structure that is ...
