Embodiment
[0020] Example: such as figure 1 , figure 2 with image 3 As shown, a super-large-diameter welded ball valve using an improved adjusting rod structure includes a valve body 2 and an extension pipe 1. An extension pipe 1 is provided on both sides of the valve body 2, and a ball 6 is arranged inside the valve body 2. The pipe 1 extends from both sides of the valve body 2 to its interior and connects with the spherical surface of the ball 6 provided inside. The upper part of the ball 6 extends upwards and is provided with a cylindrical adjustment rod structure 9 beyond the valve body 2. The adjustment rod structure 9 The top is provided with a cap nut 16, and the cap nut 16 is threadedly connected with the adjusting rod structure 9, and the junction of the cap nut 16 and the top of the regulating rod structure 9 is provided with an outwardly extending handle 14, the handle 14 adopts a butterfly shape, and the handle 14 and the connection position of the adjusting rod structure...

The invention relates to the technical field of valve manufacturing, in particular to an ultra-large-diameter welded ball valve using an improved adjusting rod structure. The ultra-large-diameter welded ball valve comprises a valve body and extension pipes, the extension pipes are correspondingly arranged on the two sides of the valve body, a ball is arranged in the valve body, the extension pipesare correspondingly extended into the inner part of the valve body from the two sides of the valve body to be connected with the ball surface, a cylindrical adjusting rod structure is arranged on theupper part of the ball in an upward extending mode, and exceeds the valve body part, a cover-shaped nut is arranged at the top of the adjusting rod structure, the cover-shaped nut is connected with the adjusting rod structure in a threaded mode, the joint part of the cover-shaped nut and the adjusting rod structure is provided with a handle extending outwards, the handle is butterfly-shaped, andthe connection position of the handle and the adjusting rod structure is provided with a positioning pin for further positioning and fixation. Compared with an existing ball valve, the handle of the ultra-large-diameter welded ball valve is butterfly-shaped, manual grasping is more convenient, thus the opening and closing of the valve are more time-saving and labor-saving, and convenience and fastness are achieved.
Description
technical field [0001] The invention relates to the technical field of valve manufacturing, in particular to a super-large diameter welded ball valve using an improved adjusting rod structure. Background technique [0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, adjust and control the parameters (temperature, pressure and flow) of the conveying medium. According to its function, it can be divided into shut-off valve, check valve, regulating valve and so on. The valve is a control component in the fluid delivery system, which has functions such as cut-off, adjustment, flow diversion, reverse flow prevention, pressure stabilization, flow diversion or overflow pressure relief. [0003] Valves can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media. Valves are also divided into cast iron valves, cast steel valves, stainless steel...
