Technical Field
The utility model relates to the technical field of forged valves, in particular to a forged valve housing blank.
Background
The valve is a device for controlling the direction, pressure, and flow rate of a fluid in a fluid system, and is a device for allowing or stopping the flow of a medium (liquid, gas, or powder) in a pipe or a device and controlling the flow rate. The processing precision of the valve directly influences the sealing performance of the whole pipeline. A serious safety accident may be caused by the leakage of the valve: for example, valve leaks in petroleum pipelines may cause explosions. Therefore, the quality requirements for the valve are higher and higher, and the forged valve gradually occupies a larger market share due to the compact internal structure and safe and reliable performance. The forging valve is a processing method for applying pressure to a metal valve blank by using forging machinery to enable the metal valve blank to generate plastic deformation so as to obtain a forging piece with certain mechanical properties, a certain shape and a certain size.
The existing valve is produced mostly by casting, liquid metal is cast into a casting cavity which is matched with the valve in shape, and after the liquid metal is cooled and solidified, a valve blank with a certain shape, size and performance is obtained. The forging process is to manufacture valve blanks through blanking of forging blanks, heating of the forging blanks, forging blank preparation of rollers, die forging forming, trimming, punching, correcting and other processes.
The valve body (valve shell) is a main part forming a valve pressure cavity, is directly connected with a pipeline and controls the direction, pressure and flow of fluid with other parts of the valve. The valve body is mainly applied to the flowing and transportation of various fluids, the leakage phenomenon of the valve body which is firm again can not be avoided, people can only prolong the service life of the valve body as long as possible, compared with the leakage of the valve body, the leakage of the joint of the valve body and a pipeline is easier to occur, especially the valve body which is always in the open air or exposed outside is avoided, the wind and the sun are not avoided, the rust, the aging and the corrosion of the joint of the pipeline are easy to be caused, the valve body which is generally used does not protect the joint of the pipeline, the maintenance is more frequent, and the workload of staff is increased; there is now a new type of forged valve body that provides protection for pipe joints, such as CN201721787084.3, but this is more structurally complex, and therefore we will provide another forged valve housing blank that provides protection for pipe joints with a simplified structure and fewer parts.
