Embodiment

[0017] Example: as figure 1 and figure 2 As shown in the figure, a bonnet structure of a new type of regulating valve includes a cap top part 1 and a cap stem part 2, the cap top part 1 and the cap stem part 2 are made by integral molding technology, and the cross section of the cap top part 1 is a regular hexagon. There is a cylindrical groove 5 in the middle of the cap top part 1 and extends downward to form an inner cavity 4 inside the cap rod part 2. The outer side of the cap rod part 2 is provided with a circle of rectangular protrusions 3. The upper and lower ends of the cap top part 1 are made of Rounded corner design, the angle α of the rounded corner is 15°.

[0018] In this embodiment, the ratio of the height h1 from the upper end of the cap top part 1 to its lower end to the height h2 of the entire valve cap is 1:3, and the height h4 from the upper end of the protrusion 3 to the bottom of the cap rod part 2 is equal to the height h4 of the lower end of the protrus...

Abstract

The invention relates to the technical field of manufacturing of valves, in particular to a valve cap structure of a novel adjusting valve. The structure comprises a cap top portion and a cap rod portion, the cap top portion and the cap rod portion are manufactured through the integral forming technology, the section of the cap top portion is in a regular hexagon shape, and a cylindrical groove isformed in the middle of the cap top portion and extends downwards to form an inner cavity in the cap rod portion. The structure is simple, layout is reasonable, certain generality is achieved, the structure is embedded on the top of the valve body, the dustproof isolation effect on the interior of the valve body is achieved, protrusions on the periphery of the cap rod portion enable connection between the valve cap and the valve body to be more attached tightly, and good seal is achieved.

Description

technical field [0001] The invention relates to the technical field of valve manufacturing, in particular to a valve cap structure of a novel regulating valve. Background technique [0002] The valve is a pipeline accessory used to open and close the pipeline, control the flow direction, and 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, etc. The valve is a control component in the fluid conveying system, which has the functions of cut-off, regulation, diversion, prevention of backflow, voltage stabilization, diversion or overflow and 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 valves (201, 304, 316, etc.), ch...
