Description

Technical Field

[0001] This utility model relates to the field of electric ball valve technology, and in particular to an electric ball valve that is easy to maintain. Background Technology

[0002] Electric ball valves are a series of electric regulating ball valves composed of an electric actuator with an operating force of 8Nm to 24Nm and an electric ball valve body. They are widely used in air conditioning, refrigeration, heating and other building automatic control systems. They can accurately regulate the flow of media in the system, thereby achieving the purpose of controlling temperature, humidity, pressure and energy saving. However, the electric actuator and electric ball valve body of electric ball valves are mostly sealed as one piece or fixed at the four corners with fastening screws. Therefore, it is inconvenient to disassemble and maintain them. In addition, the pipeline of proportional ball valves is also fixed in position. When installing electric ball valves, if there are obstacles in the installation position, it is impossible to install smoothly. Or, if it is necessary to change the connection direction of the pipeline, the entire electric ball valve needs to be disassembled, adjusted and reinstalled, which is troublesome and requires a lot of work. Utility Model Content

[0003] The main objective of this invention is to provide an easy-to-maintain electric ball valve that can effectively solve the technical problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: An easy-to-maintain electric ball valve includes an electric actuator and an electric ball valve body. The electric ball valve body is fixedly installed on the lower surface of the electric actuator, and a disassembly plate is movably installed on the upper surface of the electric actuator. A locking switch is movably installed on the upper surface of one end of the disassembly plate. An installation sleeve is fixedly installed on the lower surface of the electric ball valve body, and a pipe is fixedly installed on the lower surface of the installation sleeve.

[0005] More preferably, the pipe has connection ports fixedly installed on both ends, the inner surface of the connection ports is threaded, a connecting pipe is fixedly installed on the upper surface of the pipe, a connecting disc is fixedly installed on the upper surface of the connecting pipe, and the pipe is fixed to the mounting sleeve by bolt and nut assembly.

[0006] More preferably, an embedded post is fixedly installed on the lower surface of the locking switch, and a locking foot is fixedly installed on the surface of the embedded post and below it, the number of the locking feet being three.

[0007] More preferably, a fixing block is fixedly installed on the surface of the mounting sleeve near the upper end, and the number of fixing blocks is four. An mounting head is fixedly installed on the upper surface of the mounting sleeve at the middle. Mounting holes are opened on the upper surface of the fixing block and the lower surface of the mounting sleeve at the edge. The mounting sleeve is fixed to the electric ball valve body by fasteners passing through the fixing block.

[0008] More preferably, a rotating shaft is fixedly installed on both sides of one end of the disassembly plate, and the disassembly plate is movably connected to the electric actuator through the rotating shaft. A locking groove adapted to the locking switch is opened on the upper surface of one end of the electric ball valve body, and an installation groove adapted to the installation head is opened on the lower surface of the electric ball valve body.

[0009] Compared with the prior art, the present invention has the following beneficial effects: In this invention, a disassembly plate and a locking switch work together. By rotating the locking switch, the locking pin of the locking switch aligns with the locking groove of the electric ball valve body, allowing the disassembly plate to be flipped open. This enables the electric actuator and the electric ball valve body to be inspected without having to open the covers of each actuator and the electric ball valve body individually. After inspection, the disassembly plate is flipped back to its original position, and then the locking switch is rotated so that the locking pin is embedded in the locking groove and misaligned with the groove, preventing the disassembly plate from being opened. This method allows for quick inspection and allows the disassembly plate to be reinstalled in its original position.

[0010] With the installation sleeve in place, even after the fasteners securing the installation sleeve are removed, the installation sleeve remains connected to the electric ball valve body via the installation head. At this point, the installation sleeve can be rotated to adjust the orientation of the connection ports at both ends of the pipeline, so that it can be connected to the external pipeline in the desired direction.

[0013] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0014] like Figure 1-4The diagram shows an easy-to-maintain electric ball valve, comprising an electric actuator 1 and an electric ball valve body 2. The electric ball valve body 2 is fixedly mounted on the lower surface of the electric actuator 1, and a disassembly plate 3 is movably mounted on the upper surface of the electric actuator 1. A locking switch 4 is movably mounted on the upper surface of one end of the disassembly plate 3. An installation sleeve 5 is fixedly mounted on the lower surface of the electric ball valve body 2, and a pipe 6 is fixedly mounted on the lower surface of the installation sleeve 5.

[0015] In a preferred embodiment: connectors 601 are fixedly installed on both ends of the pipe 6, the inner surface of the connectors 601 is threaded, a connecting pipe 602 is fixedly installed on the upper surface of the pipe 6, a connecting plate 603 is fixedly installed on the upper surface of the connecting pipe 602, and the pipe 6 is fixed to the mounting sleeve 5 by bolt and nut assembly.

[0016] In a preferred embodiment: a mounting post 401 is fixedly installed on the lower surface of the locking switch 4, and a locking foot 402 is fixedly installed on the surface of the mounting post 401 and below it, and the number of locking feet 402 is three.

[0017] In the above structure, the locking foot 402 is misaligned with the locking groove of the electric ball valve body 2, which can limit the locking switch 4, thereby preventing the disassembly plate 3 from being flipped open. When the locking foot 402 is aligned with the locking groove, the disassembly plate 3 can be flipped open.

[0018] In a preferred embodiment: a fixing block 501 is fixedly installed on the surface of the mounting sleeve 5 near the upper end, and there are four fixing blocks 501. An mounting head 502 is fixedly installed on the upper surface of the mounting sleeve 5 in the middle. Mounting holes 503 are opened on the upper surface of the fixing block 501 and the lower surface of the mounting sleeve 5 at the edge. The mounting sleeve 5 is fixed to the electric ball valve body 2 by fasteners passing through the fixing blocks 501.

[0019] In the above structure, after the fasteners are removed, the mounting sleeve 5 can be rotated to adjust the orientation of the pipe 6 installed with the mounting sleeve 5. The mounting sleeve 5 is always connected to the electric ball valve body 2 during the rotation process, and the adjustment of the orientation of the pipe 6 does not require adjustment of the installation orientation of the electric actuator 1.

[0020] In a preferred embodiment: a rotating shaft is fixedly installed on both sides of one end of the disassembly plate 3. The disassembly plate 3 is movably connected to the electric actuator 1 through the rotating shaft. A locking groove adapted to the locking switch 4 is opened on the upper surface of one end of the electric ball valve body 2. An installation groove adapted to the mounting head 502 is opened on the lower surface of the electric ball valve body 2.

[0021] In use, by rotating the locking switch 4, the locking foot 402 of the locking switch 4 aligns with the locking groove of the electric ball valve body 2, allowing the disassembly plate 3 to be flipped open. This enables the electric actuator 1 and the electric ball valve body 2 to be inspected without having to open the covers of each actuator 1 and the electric ball valve body 2 individually. After inspection, the disassembly plate 3 is flipped back to its original position, and then the locking switch 4 is rotated so that the locking foot 402 is embedded in the locking groove and misaligned with it, preventing the disassembly plate 3 from being opened. This method allows for quick inspection and allows the disassembly plate 3 to be reinstalled in its original position. After the fasteners of the mounting sleeve 5 are removed, the mounting sleeve 5 is always connected to the electric ball valve body 2 through the mounting head 502. At this time, the mounting sleeve 5 can be rotated to adjust the orientation of the connection ports 601 at both ends of the pipe 6 so that it can be connected to the external pipe in the required direction. Since the ball valve structure inside the electric ball valve body 2 extends into the inside of the pipe 6 through the mounting sleeve 5, the sealing performance after the mounting sleeve 5 is rotated and adjusted must ensure that it will not affect the lifting and lowering of the ball valve structure. The threaded hole for matching the fastener can be pre-opened on the lower surface of the electric ball valve body 2, or it can be temporarily opened as needed.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
