Description

Technical Field

[0001] The utility model relates to the technical field of ball valves, in particular to a metal ball valve sealing structure. Background Art

[0002] A ball valve is a valve in which the valve stem drives the spherical through-hole valve core in the valve body to rotate around the axis of the ball valve. Ball valves are now widely used in oil refining, long-distance pipelines, chemicals, papermaking, pharmaceuticals, water conservancy, electricity, municipal administration, steel and other industries.

[0003] During the use of existing ball valves, the internal ball valve and valve body often produce certain wear after long-term use, which further leads to water leakage when closed, further resulting in poor sealing of the ball valve. Once leakage occurs, the existing ball valve cannot perform timely detection and alarm, resulting in waste of water resources. Utility Model Content

[0011] Compared with the prior art, the advantages of the utility model are:

[0012] 1. The utility model has the following effects: when the rotating frame is rotated, the rubber cover is often ensured to be away from the ball valve body, thereby changing the problem that the existing ball valve body is worn between the ball valve body and the inner wall of the spherical cavity due to long-term use, thereby causing water leakage when closed, thereby ensuring the sealing of the ball valve, and a sealing rubber ring is arranged inside to achieve the sealing of the contact position between the rotating frame and the main box body, thereby ensuring that the ball valve is always in the best sealing state, thereby extending the service life and further ensuring the practicality of the ball valve.

[0013] 2. The effect of the utility model is that: under the influence of gravity, water enters the storage chamber along the main box body. At this time, the water level in the storage chamber rises, thereby covering the water level sensor. At this time, the water level sensor begins to detect the entry of water, and then transmits the signal to the controller. At this time, the controller transmits the signal to the left and right symmetrical alarm. At this time, the alarm starts to sound the alarm, thereby ensuring that the staff can be reminded in time to carry out maintenance and replacement, thereby realizing the collection of water leakage, thereby gaining precious time, further preventing the waste of water resources, and ensuring the practicality of the ball valve.

[0022] Embodiment 1

[0023] See also Figure 1-Figure 5 , is the first embodiment of the utility model, which provides an embodiment of a metal ball valve sealing structure, including a main box 11, wherein the main box 11 is provided with two groups of push chambers 14 symmetrically on the left and right, wherein the push chamber 14 is provided with a push frame 15 capable of moving forward and backward, wherein the push frame 15 is fixedly provided with a rubber cover 28 on one end surface close to the symmetrical side, and then the rubber cover 28 plays a sealing role, wherein the upper end surface of the main box 11 is fixedly provided with a positioning frame 19, wherein the main box 11 is provided with a spherical chamber 29, wherein the spherical chamber 29 is provided with a rotating ball valve body 17, wherein the upper end surface of the ball valve body 17 is fixedly provided with a rotating frame 18 and passes through the upper end surface of the main box 11 and the positioning frame 19, wherein the lower end surface of the main box 11 is fixedly provided with a storage frame 23, wherein the storage frame 23 is provided with a storage chamber 24 opening upward, wherein the lower wall of the storage chamber 24 is fixedly provided with two groups of water level sensors 25 symmetrically on the front and back, and then the water level sensor 25 plays a role of detecting water.

[0024] Two groups of left-right symmetrical alarms 27 are fixedly provided on the left and right end surfaces of the storage rack 23, so that the alarms 27 play an alarm role. A controller 26 is fixedly provided on the front end surface of the storage rack 23, so that the controller 26 plays a coordinated role in regulating various movements.

[0025] A sealing rubber ring 20 is fixedly provided on the upper wall of the positioning frame 19. The sealing rubber ring 20 is arranged in a circular ring shape. A threaded cover 21 is rotatably provided on the outer surface of the positioning frame 19 and covers the sealing rubber ring 20, so that the sealing rubber ring 20 plays a sealing role.

[0026] Two groups of water pipes 22 are fixedly disposed on the front and rear end surfaces of the main box body 11 , which are symmetrical in front and back. An inlet cavity 16 is disposed in the pushing frame 15 .

[0027] A driving shaft 13 is rotatably provided between the front and rear walls of the driving chamber 14, and the driving shaft 13 is threadedly matched with the driving frame 15. A driving motor 12 is fixedly provided in the inner wall of the driving chamber 14 away from the center, and the end face of the driving shaft 13 away from the symmetry is dynamically connected to the driving motor 12.

[0028] Specific workflow:

[0029] During use, water in the front water pipe 22 enters the cavity 16, and then flows to the rear water pipe 22 through the ball valve body 17. After the rotating frame 18 rotates, the two front and rear symmetrical driving motors 12 start to start, thereby driving the driving shaft 13 to start rotating, and then driving the driving frame 15 and the rubber cover 28 to start moving toward each other along the driving cavity 14. At this time, the rubber cover 28 seals the contact position between the ball valve body 17 and the main box body 11. When the rotating frame 18 is rotated, it is often ensured that the rubber cover 28 is away from the ball valve body 17, thereby changing the existing ball valve body 17 due to long-term use, which leads to wear between the ball valve body 17 and the inner wall of the spherical cavity 29, thereby causing water leakage when closed, thereby ensuring the sealing of the ball valve. A sealing rubber ring 20 is provided inside to achieve sealing of the contact position between the rotating frame 18 and the main box body 11.

[0030] When the ball valve reaches the end of its service life or has a leakage problem, water, under the influence of gravity, flows along the main box body 11 into the storage chamber 24. The water level in the storage chamber 24 rises, thereby covering the water level sensor 25. The water level sensor 25 begins to detect the entry of water and transmits a signal to the controller 26. The controller 26 transmits a signal to the left and right symmetrical alarm 27, which then starts to sound an alarm.

[0031] The above description is only a specific embodiment of the present invention, but the technical features of the present invention are not limited thereto. Any changes or modifications made by any technician in the field of the present invention are included in the patent scope of the present invention.
