Embodiment

[0016] Example: such as figure 1 As shown, a flow regulating plate suitable for flow regulating fully welded ball valves includes a flow regulating plate body 1 made of metal materials. The flow regulating plate body 1 is in an elliptical shape as a whole. 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 .

[0017] In this embodiment, the 12 flow regulating holes 3 provided on the upper part of the flow regulating plate body 1 are oval in shape, and the two flow regulating holes 3 have the largest area and are respectively arranged on both sides of the flow ...

Abstract

The invention relates to the technical field of valve manufacture, in particular to a flow adjusting plate suitable for a flow adjusting all-welded ball valve. The flow adjusting plate includes a flowadjusting plate body made of a metal material, the whole flow adjusting plate body is oval, a groove is horizontally formed in the middle portion of the flow adjusting plate body, the length of the groove is equal to a half that of the flow adjusting plate body, and flow adjusting holes are evenly distributed in the flow adjusting plate. The flow adjusting plate body is provided with the groove,so the amount of the material used can be reduced, and the flow adjusting plate facilitates mounting and maintenance. The flow adjusting holes in the flow adjusting plate body are unequal in size andhave certain distribution regularity, thereby facilitating flow adjustment.

Description

technical field [0001] The invention relates to the technical field of valve manufacturing, in particular to a flow regulating plate suitable for flow regulating fully welded ball valves. 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 valv...
