Description

Technical Field

[0001] This utility model relates to the field of ball valves, specifically a ball valve for CRRC. Background Technology

[0002] A ball valve is a valve driven by a valve stem that rotates around its axis. It can also be used for fluid regulation and control. Hard-seal V-type ball valves, with their V-shaped ball core and hard alloy-faced metal seat, possess strong shearing force, making them particularly suitable for media containing fibers or small solid particles. Multi-port ball valves in pipelines can flexibly control the merging, splitting, and switching of flow directions, and can also close any channel while connecting the other two. These valves should generally be installed horizontally in pipelines. For applications requiring a single direction or in challenging areas, a dedicated ball valve is necessary. Therefore, a dedicated ball valve for CRRC is required for its use.

[0003] The existing CRRC-specific ball valve cannot be efficiently and quickly controlled during operation, nor can its internal components be inspected and maintained, thus failing to extend its service life. Therefore, there is an urgent need for a CRRC-specific ball valve. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a CRRC-specific ball valve to solve the problems of existing CRRC-specific ball valves, which cannot efficiently and quickly control the ball valve during use, nor can they inspect and maintain the internal parts of the ball valve during use, thus failing to improve the service life of the ball valve.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a CRRC-specific ball valve, comprising a front end housing, a connecting hole at the front end of the front end housing, a rear end housing mounted on one end of the front end housing, a threaded rod mounted on one end of the rear end housing, a nut mounted on one end of the threaded rod, an operating platform mounted on the upper end of the rear end housing, a stabilizing frame mounted on the upper end of the operating platform, a movable groove at one end of the stabilizing frame, a nut mounted on the upper end of the stabilizing frame, a control rod mounted on the upper end of the rear end housing, a slot at one end of the control rod, and a buckle mounted on one end of the slot.

[0006] Preferably, the front end housing is threadedly connected to the rear end housing via a threaded rod, and the front end housing and the rear end housing fit together tightly.

[0007] Preferably, the operating table is welded to the rear housing, and the operating table has an open design.

[0008] Preferably, the stabilizing frame is threadedly connected to the operating table via a nut, and the stabilizing frame is distributed parallel to the operating table.

[0009] Preferably, the control rod is movably connected to the rear housing, and the buckle is engaged with the control rod through a slot.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] This utility model features a front shell, a rear shell, an operating table, a stabilizing frame, a control rod, a slot, and a buckle. The operating table installed in the device can adjust the control rod, and it can be fixed in use by the buckle engaging with the slot on the control rod. After being fixed, the control rod can be restricted, facilitating control operation.

[0012] This utility model, with its front end housing, connecting hole, rear end housing, threaded rod, and nut, allows for easy assembly and disassembly of the device via the front and rear end housings. This enables inspection and maintenance of the entire CRRC-specific ball valve, thereby extending its service life. Attached Figure Description

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0019] The embodiments of this utility model will be described below based on its overall structure.

[0020] Please see Figure 1-4A ball valve specifically designed for CRRC (China Railway Rolling Stock Corporation) includes a front housing 1 with a connection hole 2 at its front end. A rear housing 3 is mounted to one end of the front housing 1, and a threaded rod 4 is mounted to one end of the rear housing 3. The front housing 1 is threadedly connected to the rear housing 3 via the threaded rod 4, and the two housings fit tightly together. The connection between the front housing 1 and the rear housing 3 via the threaded rod 4 maintains a seal and facilitates disassembly for inspection and maintenance of the ball valve's internal components. A nut 5 is mounted to one end of the threaded rod 4, and an operating platform 6 is mounted on the upper end of the rear housing 3. A stabilizing frame 7 is installed on the upper end of the operating table 6. A movable groove 8 is opened at one end of the stabilizing frame 7. A nut 9 is installed on the upper end of the stabilizing frame 7. A control rod 10 is installed on the upper end of the rear housing 3. A slot 11 is opened at one end of the control rod 10. A buckle 12 is installed at one end of the slot 11. The control rod 10 is movably connected to the rear housing 3, and the buckle 12 is engaged with the control rod 10 through the slot 11. The control rod 10 installed in the device can control the internal components of the ball valve. The control rod 10 can be fixed by the buckle 12 cooperating with the slot 11 opened at one end of the control rod 10.

[0021] Working Principle: During use, first check for damage to the ball valve components inside the rear housing 3. After confirming there is no damage, connect the front housing 1 and the rear housing 3 by tightening the threaded rod 4. Secure the front housing 1 and rear housing 3 tightly with the nut 5. Once fixed, install and fix the stabilizing frame 7 in the device to the operating table 6 using the nut 9. After fixing, the control rod 10 passes through the operating table 6 and the stabilizing frame 7. The installed control rod 10 can control and adjust the ball valve. To prevent operational errors, the control rod 10 is fixed in place using a slot 11 and a buckle 12. This fixes the position of the control rod 10, facilitating operation of the ball valve. The device is assembled using the front housing 1 and the rear housing 3, facilitating disassembly and allowing for inspection and maintenance of the entire CRRC-specific ball valve. This completes the device's operation. Content not described in detail in this manual is prior art known to those skilled in the art.

[0022] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
