Description

Technical Field

[0001] The utility model relates to the technical field of ball valves, in particular to an integral double-blocking and double-discharging ball valve. Background Art

[0002] Integral double block and double bleed ball valve, usually referred to as DBB ball valve, is widely used in fluid control systems. Its unique design enables it to have the functions of blocking, bleed and double shutoff.

[0003] The integral double-block double-bleed ball valve is controlled by two valve stems. A handle is installed on the outside of the valve stem. The operator pushes the handle to rotate the valve stem. The handle is the direct operating part of the valve stem. Its design facilitates the operator to quickly and accurately control the valve's opening and closing status, ensuring that the operator can operate easily and comfortably.

[0004] However, if the operator accidentally touches the handle, it may cause the handle to rotate, causing the valve body to change state, thereby affecting the normal operation of the valve body. Utility Model Content

[0023] Example

[0024] like Figure 1 , Figure 2 , Figure 3 and Figure 4 The technical solution in the embodiment of the present application effectively solves the technical problem that the operator may accidentally touch the handle 2 and easily cause the handle 2 to rotate, causing the state of the valve body 1 to change, thereby affecting the normal operation of the valve body 1. The overall idea is as follows:

[0025] In response to the problems existing in the prior art, the utility model provides an integral double-blocking double-discharge ball valve, which includes a valve body 1, two handles 2 that are rotatably connected to the outside of the valve body 1, and a limiting mechanism is arranged on the outside of the valve body 1, the limiting mechanism including a support frame 3, a limiting plate 4, a through hole 5, a limiting hole 6, a threaded hole 7 and a limiting screw 8. The support frame 3 is arranged on the outside of the valve body 1, the support frame 3 is L-shaped, the limiting plate 4 is slidably connected to the outside of the support frame 3, the through hole 5 is opened on the outside of the limiting plate 4, the limiting plate 4 is slidably connected to the outside of the support frame 3 through the through hole 5, there are two limiting holes 6, the two limiting holes 6 are respectively opened at both ends of the limiting plate 4, there are two threaded holes 7, the two threaded holes 7 are both opened on the outside of the support frame 3, there are two limiting screws 8, the two limiting screws 8 are respectively threadedly connected to the inside of the two threaded holes 7, the limiting plate 4 is located at the two threaded holes When the two handles 2 are in parallel, the limit plate 4 is slidably connected to the outside of the handle 2 through the limit hole 6. At this time, the two limit screws 8 can be threadedly connected to the inside of the threaded hole 7. At this time, the limit plate 4 is fixed and cannot move, and the two handles 2 are also fixed and cannot move. When the two handles 2 are in the same straight line, the limit plate 4 is pushed to make the limit plate 4 close to the valve body 1 until the two ends of the limit plate 4 are respectively fitted with the outside of the two handles 2. At this time, a limit screw 8 is threadedly connected to the position of the threaded hole 7. At this time, the limit plate 4 cannot move, and the two handles 2 are also fixed and cannot rotate. When the valve of the integral double-blocking double-discharge ball valve is in the fully open or fully closed state, the handle 2 is locked to prevent the operator from accidentally touching the handle 2 and ensure the normal operation of the valve body 1.

[0026] A sliding frame 9 is fixedly installed on the outside of the valve body 1. The sliding frame 9 consists of an arc plate and two rectangular plates. The two rectangular plates are fixedly installed at both ends of the arc plate. A sliding groove 10 is opened on the outside of the support frame 3. The support frame 3 is slidably connected to the outside of the sliding frame 9 through the sliding groove 10. By setting the sliding frame 9 and cooperating with the support frame 3, the card plate 11 is pulled to make the card plate 11 away from the support frame 3. At this time, the restriction of the card plate 11 on the support frame 3 disappears. At this time, the support frame 3 can be rotated downward and away from the handle 2, thereby avoiding the support frame 3 from standing upright and affecting the staff's maintenance of the handle 2.

[0027] A card plate 11 is provided on the outside of the support frame 3. The card plate 11 is composed of an L-shaped plate and a rectangular plate. The card plate 11 is attached to the outside of the support frame 3. A slide groove 12 is provided on the outside of the support frame 3. The card plate 11 is slidably connected to the inside of the slide groove 12. A spring 13 is fixedly connected to the inside of the slide groove 12. The card plate 11 is fixedly connected to the outside of the spring 13. A built-in groove 14 is provided inside the slide groove 12. There are two built-in grooves 14. The built-in plate 15 is slidably connected to the inside of the built-in groove 14. There are two built-in plates 15. The built-in plates 15 are fixedly installed on the side of the card plate 11 close to the spring 13 to prevent the connection between the card plate 11 and the slide groove 12 from being released.

[0028] Working principle:

[0029] In the first step, the card plate 11 is pulled to move toward the outside of the slide groove 12. At this time, the spring 13 is stretched, and the support frame 3 is rotated upward until the support frame 3 is upright. At this time, the card plate 11 is released. Under the action of the spring 13, the card plate 11 is attached to the surface of the support frame 3. At this time, the support frame 3 is blocked and cannot be rotated downward;

[0030] In the second step, when the two handles 2 are parallel, the limit plate 4 is slidably connected to the outside of the support frame 3 through the through hole 5. At this time, the limit plate 4 is slidably connected to the outside of the two handles 2 through the two limit holes 6. At this time, the two limit screws 8 can be threadedly connected to the inside of the threaded holes 7. At this time, the limit plate 4 is located between the two limit screws 8. At this time, the limit plate 4 is fixed and cannot move, and the two handles 2 are also fixed and cannot rotate. When the two handles 2 are in the same straight line, the limit plate 4 is pushed to make the limit plate 4 close to the valve body 1 until the two ends of the limit plate 4 are respectively fitted with the outside of the two handles 2. At this time, the threaded hole 7 at one end close to the clamping plate 11 is connected to the limit screw 8. At this time, the limit plate 4 cannot move, and the two handles 2 are also fixed and cannot rotate. Therefore, when the valve of the integral double-blocking double-discharge ball valve is in the fully open or fully closed state, the handle 2 can be fixed.

[0031] Finally, it should be noted that the above embodiments are merely examples for the purpose of illustrating the present invention and are not intended to limit the embodiments. Those skilled in the art will readily appreciate that other variations or modifications based on the above description are possible. It is not necessary and impossible to provide an exhaustive list of all possible embodiments. However, any obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
