Description

Technical Field

[0001] The utility model relates to the technical field of valves, and particularly relates to an anti-corrosion two-piece ball valve. Background Art

[0002] A ball valve is used to open and close a pipeline, control the flow direction, and regulate and control the conveying medium (pressure, flow rate). The valve stem of the ball valve can be used to adjust the angle of the valve ball to achieve opening and closing of the pipeline, control the flow direction, and regulate and control the conveying medium. During the use of the anti-corrosion two-piece ball valve, the surface of the ball valve is usually treated with an anti-corrosion coating to ensure the anti-corrosion function of the two-piece ball valve in the use environment.

[0003] However, during the use of the anti-corrosion two-piece ball valve, when the environmental humidity is high, it is extremely easy to affect the anti-corrosion performance, thereby affecting its service life for maintaining the anti-corrosion effect, and there are deficiencies in anti-corrosion performance. Summary of the Utility Model

[0004] The purpose of the utility model is to provide an anti-corrosion two-piece ball valve, which has the function of prolonging the anti-corrosion life.

[0006] By adopting the above technical solutions, when the anti-corrosion two-piece ball valve encounters a situation where the environmental humidity is high, the desiccant packet can continuously adsorb moisture in the air for a period of time, thereby avoiding the influence on the anti-corrosion performance of the ball valve body, and the desiccant packet can be replaced regularly by opening the breathable end cover during use, thereby having the function of prolonging the anti-corrosion life. In addition, by arranging the arc-shaped cavity shell and two breathable end covers facing both ends of the ball valve body, the adsorption range and adsorption effect of moisture around the ball valve body are improved.

[0007] The further setting of the utility model is: an embedding groove for the breathable end cover to be embedded is arranged at the opening edge of the arc-shaped cavity shell, a notch is arranged at the bottom of the arc-shaped cavity shell, the anti-detachment structure includes a limiting groove arranged at the corresponding notch of the breathable end cover, and a spring piece arranged in the notch and having an elastic protrusion embedded in the limiting groove.

[0008] By adopting the above technical solution, the anti-drop structure includes a limiting groove arranged at the notch corresponding to the breathable end cover, and a spring sheet arranged in the notch and having an elastic protrusion embedded in the limiting groove. The elastic protrusion of the spring sheet is embedded in the limiting groove for limiting and fixing, so as to prevent the breathable end cover from falling off.

[0009] The utility model is further configured as follows: a gripping end for easy gripping is provided on the ventilating end cover.

[0010] By adopting the above technical solution and providing a holding end, it is convenient to overcome the limitation of the limiting groove by the elastic protrusion of the spring piece, and it is convenient to directly remove the breathable end cover.

[0011] The utility model is further configured as follows: the arc-shaped installation cavity surrounds the middle part of the ball valve body, and the arc-shaped installation cavity is larger than half of a circle.

[0012] By adopting the above technical solution, the adsorption effect of the desiccant package is guaranteed by ensuring the range of the arc-shaped installation cavity.

[0013] The utility model is further configured as follows: a plurality of second air holes distributed in an arc-shaped array are arranged on the peripheral side of the arc-shaped cavity shell.

[0014] By adopting the above technical solution, a plurality of second air holes distributed in an arc-shaped array are provided on the peripheral side of the arc-shaped cavity shell, thereby improving the adsorption range and adsorption effect of moisture around the ball valve body.

[0018] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0019] Embodiment: A corrosion-resistant two-piece ball valve, such as Figure 1As shown in the figure, it includes a ball valve body 1 with a water inlet end and a water outlet end. An arc-shaped cavity shell 2 with both ends connected to the ball valve body 1 is arranged on the circumferential side of the ball valve body 1. An arc-shaped installation cavity is formed between the arc-shaped cavity shell 2 and the ball valve body 1. A desiccant package 3 is embedded in the arc-shaped installation cavity. A breathable end cover 4 is detachably connected between the two ends of the ball valve body 1 and the arc-shaped cavity shell 2. A plurality of first breathable holes 41 arranged in an arc array are provided on the breathable end cover 4. An anti-detachment structure 5 for preventing the breathable end cover 4 from falling off is arranged between the breathable end cover 4 and the arc-shaped cavity shell 2.

[0020] As Figure 1 and Figure 2 shown in the figure, an embedding groove 21 for the breathable end cover 4 to be embedded is arranged at the opening edge of the arc-shaped cavity shell 2. A notch is arranged at the bottom of the arc-shaped cavity shell 2. The anti-detachment structure 5 includes a limiting groove 51 arranged at the corresponding notch of the breathable end cover 4, and a spring piece 52 arranged in the notch and having an elastic protrusion embedded in the limiting groove 51.

[0021] As Figure 1 shown in the figure, a holding end 42 for convenient holding is arranged on the breathable end cover 4. The arc-shaped installation cavity surrounds the middle part of the ball valve body 1, and the arc-shaped installation cavity is larger than a semi-circle. A plurality of second breathable holes 22 arranged in an arc array are provided on the circumferential side of the arc-shaped cavity shell 2.

[0022] Implementation effect: When the corrosion-proof two-piece ball valve encounters a situation where the humidity of the use environment is relatively high, the desiccant package 3 can continuously adsorb moisture in the air for a period of time, thereby preventing the corrosion-proof performance of the ball valve body from being affected. And during use, the breathable end cover 4 can be opened regularly to replace the desiccant package 3, so as to have the effect of prolonging the corrosion-proof life. In addition, by arranging the arc-shaped cavity shell 2 and two breathable end covers 4 facing both ends of the ball valve body, the adsorption range and adsorption effect of moisture around the ball valve body 1 are improved.

[0023] By arranging the holding end 42, it is convenient to overcome the limitation of the elastic protrusion of the spring piece 52 on the limiting groove 51 and directly remove the breathable end cover 4. By ensuring the size range of the arc-shaped installation cavity, the adsorption effect of the desiccant package 3 is ensured. By arranging a plurality of second breathable holes 22 arranged in an arc array on the circumferential side of the arc-shaped cavity shell 2, the adsorption range and adsorption effect of moisture around the ball valve body 1 are improved.
