Air release valve with detachable valve body and manufacturing method thereof.

Abstract

The invention relates to an air release valve with a detachable valve body and a manufacturing method thereof. The air release valve with the detachable valve body comprises the valve body; end flanges are arranged at inlet and outlet ends of the valve body and used for connecting with a pipeline; the top of the valve body is provided with a middle flange; the valve body is composed of two symmetrical half-valve bodies that are butted and fixed; a sealing gasket is arranged between the two half-valve bodies; the shape of the sealing gasket is matched with the shape of the contact faces of thetwo half-valve bodies; the two half-valve bodies are fixed by hoops at the two end flanges and a hoop at the middle flange; positioning plates are welded to the bottoms of the two half-valve bodies; and the two positioning plates are in screw connection. The air release valve with the detachable valve body is convenient to disassemble, so that washing condition is easy to observe, and under the working condition, the washing condition of other valves in actual working is evaluated; parts can be replaced in time; when slag is accumulated in the valve body of the valve, the valve body can be disassembled for cleaning; when a fluid experiment is carried out, the experiment condition of the structure can be observed more visually so that the experiment cost is greatly reduced; the experiment can be repeatedly carried out; and the wall thickness data can be collected during the subsequent flush experiment.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to a vent valve with a detachable valve body and a manufacturing method thereof. Background technique [0002] The existing vent valve has the following disadvantages: 1. The valve body is integrally cast or forged, and the fluid scouring situation cannot be observed in actual use; 2. It is difficult to deal with slag accumulation inside the valve body, causing the valve to block and the valve cannot be opened and closed; 3. , It is impossible to observe the fluid test situation intuitively; 4. When replacing the internal parts, the valve needs to be disassembled to replace the internal parts. Contents of the invention [0003] The purpose of the present invention is to provide a detachable valve body venting valve and its manufacturing method, so that the valve body can be disassembled at any time under actual working conditions, the valve body flushing situation can be observed, ...
