Technical Field

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.

Background

Valves are plumbing accessories used to open and close a pipe, control flow direction, regulate and control parameters of the transport medium (temperature, pressure and flow). According to their function, they can be classified into shut-off valves, check valves, regulating valves, and the like. The valve is a control part in a fluid conveying system and has the functions of stopping, adjusting, guiding, preventing counter flow, stabilizing pressure, shunting or overflowing and relieving pressure and the like.

The valve can be used for controlling the flow of various types of fluids such as air, water, steam, various corrosive media, slurry, oil products, liquid metal, radioactive media and the like. The valves are further classified into cast iron valves, cast steel valves, stainless steel valves (201, 304, 316, etc.), chrome molybdenum steel valves, chrome molybdenum vanadium steel valves, dual-phase steel valves, plastic valves, nonstandard valves, etc. according to the material.

The valve seat of the ball valve is composed of a Teflon carbide sealing ring and a disk spring, so that the ball valve has strong adaptability to pressure and temperature changes, and cannot generate any leakage slip in the range of marked pressure and temperature. The integral welded ball valve is generally formed by pressing a carbon steel seamless steel pipe, has good sealing performance and corrosion resistance, and is widely applied to the field of long-distance pipelines such as natural gas, petroleum, heat supply, chemical engineering, thermal power grids and the like. However, the existing ball valve has great limitation and cannot meet the requirement of modern industrial production.

At present, the demand of ultra-large-diameter all-welded ball valves for long-distance pipelines of heat supply projects in various big cities is increased day by day, and due to the limitation of domestic technology and manufacturing level, required valves are mainly imported, so that the project cost is increased.

Disclosure of Invention

The invention aims to provide a flow regulating plate for an ultra-large-diameter all-welded ball valve.

In order to achieve the purpose, the invention adopts the following technical scheme:

the utility model provides a flow regulating plate for ultra-large-diameter all-welded ball valve, the flow regulating plate body of making including metal material, the whole oval shape that is of flow regulating plate body, flow regulating plate body mid portion transversely is provided with a recess, the length of recess equals half of flow regulating plate body length, evenly distributed has the flow regulating hole on the flow regulating plate, divide the flow regulating plate body into upper and lower two parts with the recess symmetry, the upper portion of flow regulating plate body is provided with 12 flow regulating holes, the lower part of flow regulating plate body is provided with 8 flow regulating holes, the shape of 12 flow regulating holes that the upper portion of flow regulating plate body set up is oval, wherein 2 the area of flow regulating hole sets up respectively in the both sides of flow regulating plate body the most, other 10 flow regulating holes divide into two sets of settings between these two biggest flow regulating holes of area.

The invention further improves that two groups of flow regulating holes are regularly arranged on the upper part of the flow regulating plate body, wherein the area of one group of flow regulating holes is from small to large, and the area of the other group of flow regulating holes is from large to small.

The invention further improves the structure that 8 flow regulating holes arranged at the lower part of the flow regulating plate body are divided into two groups which are arranged up and down, each group comprises 4 flow regulating holes, the areas of the upper group of 4 flow regulating holes are equal, the areas of the lower group of 4 flow regulating holes are equal, and the area of the upper group of flow regulating holes is larger than that of the flow regulating holes in the next circle.

The flow regulating hole body is provided with the groove, so that the consumption of materials can be reduced, the flow regulating hole body is convenient to install and maintain, and the flow regulating holes in the flow regulating plate body are different in size and are distributed regularly, so that the flow is convenient to regulate.
