Abstract
Description
Technical Field
[0001] This application belongs to the technical field of ball valves, and particularly relates to a forged part of a ball valve body. Background Art
[0002] Ball valves are mainly used for cutting off, distributing, and changing the flow direction of the medium in pipelines. They can be tightly closed with only a 90-degree rotation operation and a very small rotational torque. Therefore, due to their advantages such as simple operation, they are widely used in industries such as petroleum refining, long-distance pipelines, chemical engineering, papermaking, pharmaceuticals, water conservancy, electric power, municipal engineering, and steel. The ball valve came out in the 1950s. With the rapid development of science and technology and the continuous improvement of production processes and product structures, it has quickly developed into a main type of valve in just 40 years. For the relatively mature current ball valve technology, the unique structural defects are still difficult to overcome.
[0003] The existing Chinese patent with the publication number CN206958302U discloses a stainless steel electric ball valve, which is mainly used for automatic control and regulation of the flow rate of PE pipes in outdoor valve chambers or humid environments. It includes a valve core, a valve stem, and a housing made of stainless steel. The characteristic is that the valve core is connected to an electric actuator through the valve stem. The inlet and outlet of the stainless steel housing are solidified with polyethylene material sockets for electrofusion welding. A stainless steel sheath is provided outside the polyethylene material socket, and the stainless steel sheath is integrally connected to the stainless steel housing.
[0004] Although the above-mentioned ball valve improves the service life, the housing and the valve seat on it are assembled and connected. Although there are also those with the housing and the valve seat integrally connected, they are basically injection-molded parts and castings, and there is no one in the forging field with the housing and the valve seat integrally connected. Improvements are made to this. Utility Model Content
[0005] The purpose of this application is to provide a forged part of a ball valve body for the above-mentioned existing technical problems, which can realize the integral processing and forming of the valve body main body and the valve seat by forging.
[0006] This application provides a forged part of a ball valve body, including:
[0007] A valve body main body, provided with a middle hole;
[0008] A valve seat, placed on the outer side wall of the valve body main body;
[0009] A strengthening part, placed on the outer side wall of the valve body main body and corresponding to the valve seat;
[0010] Among them, the valve seat is integrally connected to the valve body main body. The strengthening part is provided with a parting line, and the strengthening part is provided with a first draft surface on both sides of the parting line.
[0011] The valve body main body, valve seat, and strengthening part are integrally forged through forging processing to ensure the overall structural strength of the valve body main body, valve seat, and strengthening part. The valve seat is used to install the valve stem after machining, and the position of the valve seat corresponds to the installation position of the ball valve. The structural strength of this position is improved through the strengthening part. The valve body main body facilitates fluid flow through the middle hole. The valve body main body realizes forging processing through a mold. During the forging process of the valve body main body, a parting line is generated in the strengthening part by the mold. The first draft surfaces on both sides of the parting line facilitate the demolding of the ball valve body forging. The ball valve body forging is forged using metal materials such as stainless steel, copper alloy, and aluminum alloy.
[0012] Furthermore, a first transition surface is provided between the strengthening part and the valve body main body, and the first transition surface extends from the strengthening part to the outer side wall of the valve body main body.
[0013] The strengthening part and the valve body main body are connected through the first transition surface. The first transition surface facilitates the forging and forming of the forging by the forging die, and also facilitates the demolding of the forging.
[0014] Furthermore, the valve body main body includes:
[0015] A second draft surface is disposed on the outer side wall of the valve body main body, and the second draft surface is connected to the first transition surface.
[0016] The second draft surface is disposed on the outer side surface of the valve body main body. The second draft surface facilitates the demolding of the forging from the forging die after the forging is completed. The second draft surface extends from the first transition surface to the end of the valve body main body.
[0017] Furthermore, the valve seat includes:
[0018] A limiting part is disposed on the outer wall surface of the valve seat, and the limiting part is distributed around the circumference of the valve seat.
[0019] Among them, the limiting part is integrally connected between the valve body main body and the valve seat.
[0020] The limiting part provides a limiting function for other components during the subsequent use of the valve body main body. The limiting part is integrally connected to the strengthening part and the valve seat through forging and forming, improving the structural strength between the limiting part, the strengthening part, and the valve seat. One or two limiting parts are provided.
[0021] By disposing the limiting part at a position close to the parting surface of the mold, it facilitates the forging processing of the valve body main body and the demolding after forging.
[0022] Furthermore, a second transition surface is provided between the valve seat, the strengthening part, and the limiting part.
[0023] The second transition surface transitions the connection parts between the valve seat, the strengthening part, and the limiting part, facilitating the forging processing of the mold and making the structure of the valve body main body more stable and durable.
[0024] Furthermore, the reinforcing portion is provided with a plane which is disposed on both sides of the valve seat.
[0025] The plane is formed by forging or machining, and the machining and use of the valve body are facilitated through the plane.
[0026] The beneficial effects of the present application are as follows:
[0027] 1. The valve body, valve seat, reinforcing portion, and limiting portion are integrally connected, improving the overall structural strength of the ball valve body.
[0028] 2. The forging and demolding of the ball valve body are facilitated through the first draft surface, second draft surface, first transition surface, and second transition surface.
[0029] 3. The valve seat is used to install the valve stem after machining, ensuring that the ball valve body formed by forging has high structural stability. Description of the Drawings
