Technical Field

[0001] The utility model relates to the technical field of gate valve equipment, in particular to a gate valve equipment which is easy to maintain. Background Art

[0002] The gate valve is a commonly used shutoff valve, which is mainly used to connect or cut off the medium in the pipeline. It has the characteristics of simple structure, convenient operation and easy maintenance, and is widely used in various industrial fields. The gate valve consists of a movable gate. When the gate is fully closed, it can completely cut off the flow of the medium. When the gate is fully opened, it can achieve the purpose of complete flow of the medium.

[0003] At present, most gate valves are connected by flanges, which requires the removal of multiple sets of bolts during maintenance, making the maintenance work very inconvenient. In view of this, we propose a gate valve device that is easy to maintain. Utility Model Content

[0009] Preferably, the outer wall of the protective shell seat is fixedly connected to a support frame, the inner wall of the support frame is slidably connected to a clamping rod, the top of the threaded rod is fixedly connected to a driving disk, a through groove is opened on the protective shell seat, and the inner wall of the through groove is slidably connected to a clamping rod.

[0010] Preferably, a pull plate is fixedly connected to the outer wall of the clamping rod, a compression spring is welded to the outer wall of the pull plate, and one end of the compression spring away from the pull plate is welded to the outer wall of the support frame. By loosening the pull plate, the clamping rod is automatically reset through the compression spring.

[0011] Preferably, a sealing ring is clamped on the inner wall of the valve body, a connecting hole is provided on the valve body, a placement groove is provided on the valve body, a sealing ring is clamped on the inner wall of the placement groove, and the clamping rod can be slidably connected to the inner wall of the connecting hole.

[0012] Preferably, the top of the valve plate is slidably connected to a sliding clamping plate, the top of the valve plate is fixedly connected to a fixed plate, one end of the sliding clamping plate is provided with an arc-shaped notch, and the top of the sliding clamping plate is provided with a limiting groove.

[0013] Preferably, a return spring is welded to the outer wall of the fixed plate, and one end of the return spring away from the fixed plate is welded to the outer wall of the sliding card plate. The inner wall of the sliding card plate is clamped with a limiting block, and the sliding card plate is squeezed by the return spring to make the sliding card close to the sliding rod and limit the sliding rod.

[0014] The utility model provides a gate valve device that is easy to maintain and has the following beneficial effects:

[0015] (1) The gate valve device which is easy to maintain can make the clamping rod leave the connecting hole by pulling the pull plate, and then the protective shell seat can slide away from the valve body. When the slide rod leaves the valve body, the valve plate can be driven to leave the valve body. When the valve plate leaves the valve body, the valve plate and the slide rod are automatically separated because there is no limit on the inner wall of the valve body, which makes it convenient for the staff to maintain the valve plate, which is convenient and quick.

[0016] (2) When installing the gate valve device which is easy to maintain, the protective shell seat is slowly slid onto the valve body. When the inner wall of the protective shell seat contacts the end face of the valve body, the boss of the protective shell seat squeezes the sealing ring to ensure that the sealing ring can be deformed, thereby providing a sealing effect between the protective shell seat and the valve body. At the same time, the clamping rod is automatically reset by compressing the spring, so that the clamping rod can be clamped into the connecting hole to complete the installation of the protective shell seat, which is very convenient.
