Description

Technical Field

[0001] The utility model relates to the technical field of ceramic valves, and specifically relates to a three-section ceramic valve. Background Technique

[0002] A valve is a pipeline accessory used to open and close pipelines, control the flow direction, and adjust and control the parameters (temperature, pressure, and flow rate) of the conveyed medium. According to its functions, it can be divided into shut-off valves, check valves, regulating valves, etc. Valves are control components in fluid conveying systems and have functions such as cut-off, regulation, diversion, prevention of backflow, pressure stabilization, flow splitting, or overflow pressure relief. Valves used in fluid control systems range from the simplest globe valves to various valves used in extremely complex automatic control systems, and their varieties and specifications are quite numerous. In the opening and closing process of traditional valves, the sealing surfaces rub against each other relatively, resulting in significant wear. Moreover, in high-temperature environments or when the medium contains impurities, it is easy to cause scratching and jamming, leading to the rupture of the ball valve, thus affecting its service life and other issues.

[0003] As disclosed in the authorized announcement number CN2545438Y, a ceramic valve is disclosed, which includes a valve housing, a ceramic fixed piece, a ceramic moving piece, and a ceramic fixing ring. The characteristics are as follows: The ceramic moving piece is fixedly equipped with a cylindrical transmission shaft corresponding to the cylinder of the end cover, and an outer magnet is arranged inside the cylindrical transmission shaft; the main shaft of the opening device arranged outside the end cover extends into the cylinder of the end cover, and an inner magnet corresponding to and attracting the outer magnet is fixedly installed at its end. The utility model is a ceramic valve with a long service life, no leakage, controllable flow rate, simple structure, and convenient manufacturing. Although it solves problems such as simple structure and low cost, it does not solve the problems of large wear due to relative friction between the sealing surfaces during the opening and closing process and jamming in the medium containing impurities, which may cause the rupture of the ball valve, thus affecting its service life and other issues. Content of the Utility Model

[0004] The purpose of the utility model is to provide a three-section ceramic valve to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A three-section ceramic valve includes an upper valve body, a lower valve body, and a main body mechanism. The upper valve body and the lower valve body are connected, and the main body mechanism is installed inside.

[0007] The main body mechanism includes a ceramic chip core and a ball valve. The connection between the upper valve body and the lower valve body is designed to be hollow. On one side inside, a ceramic chip core is installed. At one end of the ceramic chip core, an upper valve seat is fixedly installed. Above the upper valve seat, a ball valve is movably arranged. At the upper end of the ball valve, a lower valve seat is fixedly arranged. The ball valve is movably arranged on the upper valve seat and the lower valve seat. By using ceramic materials, it can achieve extremely high wear resistance, corrosion resistance, and erosion resistance, and has advantages such as good heat insulation and small thermal expansion.

[0008] Preferably, a screw hole is provided on one side of the upper valve body. Above the screw hole, a screw rod is installed. The other end of the screw rod is threadedly connected to a nut. The nut is installed on one side of the lower valve body. By fixing the nut on the bolt, the upper valve body and the lower valve body are fixedly arranged through a flange structure to ensure its sealing performance.

[0009] Preferably, a positioning piece is installed at the connection of one side of the upper valve body and the lower valve body. The upper valve body and the lower valve body are connected by a flange. By setting the positioning piece, it is convenient to adjust the output power of the valve, accelerate the moving speed of the valve stem, overcome the friction force of the valve stem, and eliminate the influence of unbalanced force.

[0010] Preferably, a water inlet is provided at the top of the upper valve body, and a water outlet is provided at the bottom of the lower valve body. By providing the water inlet and the water outlet, the purpose of controlling the water flow is achieved.

[0011] Preferably, an interception net is installed on one side inside the main body mechanism. The inside of the ball valve is semi-circular and hollow. Inside the semi-circular hollow part, a buffer compensation elastic washer is arranged. The buffer compensation elastic washer is closely attached to the inner wall of the ball valve. The interception net is installed on one side of the water inlet. By installing the interception net on one side of the water inlet inside the main body mechanism, the impact force caused by particulate matter in high-speed water flow on the ceramic ball valve can be reduced. The impact force is further reduced by the buffer compensation elastic washer arranged on the inner wall of the hollow part of the ball valve, improving the stable and good sealing performance. And in a medium containing impurities, it is not easy to get stuck and cause the rupture of the ball valve, thus extending the service life.

[0012] Preferably, a valve core is connected to the other end outside the main body mechanism. A valve stem is installed on the valve core. One end of the valve stem is fixedly arranged on a through hole provided on one side of the ball valve. The other side of the valve stem is connected to a driving motor at the top. By controlling the valve stem on the valve core through the driving motor, the purpose of automatically controlling the opening and closing of the valve is achieved.

[0013] Compared with the prior art, the beneficial effects of the present utility model are:

[0014] 1. The three-section ceramic valve reduces the impact force on the ceramic ball valve caused by particulate matter in high-speed water flow by installing an intercepting net on one side of the internal water inlet of the main body mechanism. The impact force is further reduced by the buffer compensation elastic gasket arranged on the inner hollow wall of the ball valve, improving the sealing performance with good stability. Moreover, in a medium containing impurities, it is not easy to get stuck and cause the rupture of the ball valve, thus extending the service life.

[0015] 2. The three-section ceramic valve adopts ceramic technology and its internal structure is made of ceramic materials. Therefore, this valve has extremely high wear resistance, corrosion resistance, and erosion resistance, and has advantages such as good heat insulation and small thermal expansion. The ball is manufactured by advanced grinding equipment and technology. The ball valve rotates on the upper base and the lower base, and utilizes the self-lubricity of the ceramic to achieve fast opening and closing and good sealing performance. This ceramic valve performs particularly well in high-hardness particulate media or media with soft particles but also corrosion. The production cost of the ceramic is low and the practicability is strong. BRIEF DESCRIPTION OF THE DRAWINGS
