Description

Technical Field

[0001] This utility model relates to the field of electric valve technology, and more specifically to an electric valve that can be disassembled and cleaned. Background Technology

[0002] An electric valve mainly consists of an electric actuator, valve body, valve core (or valve disc), and seals. The electric actuator is the power source of the electric valve; an electric motor drives the valve stem, which in turn moves the valve core within the valve body, thus controlling the medium in the pipeline. The valve body is the main structure of the electric valve and is typically made of cast iron, cast steel, or stainless steel, possessing good strength and corrosion resistance. The valve core is a key component of the electric valve; its shape and material determine the valve's flow capacity, sealing performance, and service life. Seals ensure the electric valve remains sealed when closed, preventing media leakage.

[0003] Existing electric butterfly valves mostly have fixed valve plate structures, requiring complete disassembly and repair when the valve plate malfunctions. Therefore, a new technical solution is needed to address this issue. Utility Model Content

[0004] The purpose of this utility model is to provide a detachable and cleanable electric valve, which solves the problem that the valve plate structure of existing electric butterfly valves is mostly fixed and requires complete disassembly and repair when the valve plate fails.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a detachable and cleanable electric valve, comprising: a valve body, an upper mounting base provided on the upper part of the valve body, a driving device provided on the upper part of the mounting base, a driving shaft provided at the power output end of the driving device, the driving shaft extending into the valve body and rotatably connected thereto, two sets of slots provided on the surface of the driving shaft, and insertion holes provided inside the slots, a valve plate mounted on the surface of the driving shaft, and insertion posts provided on the side of the valve plate, deformation grooves provided inside the insertion posts, the deformation grooves being rectangular in structure, the head end of the insertion post being larger than the diameter of the insertion hole, locking plates provided on both sides of the insertion post, the locking plates and slots being interlocked, the surface of the locking plates being a bayonet with a semi-arc structure, a fixed flange provided on one side of the valve body, and a movable flange provided on the other side.

[0006] In a preferred embodiment of this utility model, both the fixed flange and the movable flange are provided with fixing holes inside.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] This invention features a mounting base on the upper part of the valve body, and a driving device on the upper part of the mounting base. The power output end of the driving device has a driving shaft that extends into and rotatably connects to the valve body. Two sets of slots are visible on the surface of the driving shaft, and insertion holes are located within these slots. A valve plate is mounted on the surface of the driving shaft, and insertion posts are located on the side of the valve plate. Each insertion post has a deformation groove with a rectangular structure. The head of the insertion post is larger than the diameter of the insertion hole. When insertion is required, the deformation groove presses the head of the insertion post inward, allowing it to be inserted into the insertion hole. After full insertion, the deformation groove returns to its original position, ensuring the head of the insertion post is larger than the diameter of the insertion hole, thus fixing the valve plate. This installation method facilitates valve plate installation and disassembly, increasing maintenance convenience. A fixed flange is located on one side of the valve body, and a movable flange is located on the other side, facilitating connection to pipelines. Attached Figure Description
