Problems solved by technology

However, the existing ball valves have great limitations and cannot meet the needs of modern industrial production.
[0005] At present, the demand for super large-caliber all-welded ball valves for long-distance pipelines in heating projects in major cities is increasing day by day. Due to the limitation of domestic technology and manufacturing level, the required valves are mainly imported, which increases the project cost.

Embodiment

[0015] Example: such as figure 1 As shown in the figure, a diverter plate used for a super-large caliber all-welded ball valve includes a diverter body 1 made of metal materials. Groove 2, the length of groove 2 is equal to half of the length of the flow regulating plate body 1, and flow regulating holes 3 are evenly distributed on the flow regulating plate, and the flow regulating plate body 1 is divided into upper and lower parts symmetrically by the groove 2, and the flow regulation The upper part of the plate body 1 is provided with 12 regulating holes 3 , and the lower part of the regulating plate body 1 is provided with 8 regulating holes 3 .

[0016] In this embodiment, the shape of the 12 regulating holes 3 provided on the upper part of the regulating plate body 1 is elliptical, and the two regulating holes 3 have the largest area respectively arranged on both sides of the regulating plate body 1, The other 10 flow regulating holes 3 are divided into two groups and ar...

Abstract

The invention relates to the technical field of valve manufacturing, in particular to a flow adjusting plate for an ultra-large-diameter all-welded ball valve. The flow adjusting plate comprises a flow adjusting plate body made of a metal material, wherein the whole flow adjusting plate body is in an oval shape; a groove is transversely formed in the middle of the flow adjusting plate body; the length of the groove is equal to half of the length of the flow adjusting plate body; and flow adjusting holes are evenly distributed in the flow adjusting plate. The groove is formed in the flow adjusting plate body, the material use amount can be reduced, meanwhile, mounting and maintaining are facilitated, and due to the fact that the flow adjusting holes in the flow adjusting plate body are unequal in size, certain regularity is achieved in distribution, and flow adjusting is facilitated.

Description

technical field [0001] The invention relates to the technical field of valve manufacturing, in particular to a diverter plate used for a super-large-diameter full-welded ball valve. 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 valves (20...
