Description

Technical Field

[0001] The utility model relates to the technical field of valves, in particular to a sealing and rust-proof valve. Background Art

[0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, and adjust and control the parameters of the conveying medium. In fluid pipeline systems, valves are control elements. Their main functions are to isolate equipment and pipeline systems, regulate flow, prevent backflow, and regulate and discharge pressure.

[0003] After searching, it is found that a sealed rust-proof water pipe valve is disclosed in a Chinese patent document [Application No.: CN202223120851.9]. This sealed rust-proof water pipe valve includes a pipe body, an inner groove is arranged in the top wall of the pipe body, a turntable is arranged at the top of the pipe body, the output end of the turntable passes through the outer wall of the top of the pipe body and enters the inner groove, the inner groove is slidably connected with the turntable, a circular groove is arranged in the middle of the top of the turntable, a semicircular moving block and a semicircular fixed block are arranged inside the circular groove, the moving block and the fixed block are detachably connected, an L-shaped groove is arranged at the top of the moving block and away from the fixed block, and an L-shaped push block and a limit spring are arranged inside the L-shaped groove.

[0004] The device disclosed in this patent realizes the rotation function by engaging the turntable with the moving block when in use. When the moving block is removed, the turntable will not be able to drive the device to rotate, thereby realizing the function of preventing accidental touch. However, when the device is in use, the moving block needs to be taken out to prevent accidental touch, which causes the moving block and the device as a whole to be separated. Therefore, when the device is in the anti-accidental touch state, the moving block may be lost, which seriously affects the normal use of the device. It is very inconvenient when the staff needs to adjust the valve, which seriously affects the normal use of the device. Utility Model Content

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-6As shown, a sealed rust-proof valve comprises a pipe body 1 and a connecting pipe 2, wherein the connecting pipe 2 is connected to the upper side of the pipe body 1, the connecting pipe 2 and the inside of the pipe body 1 are communicated, a first cavity 3 is provided inside the connecting pipe 2, a thread groove 4 is provided on the inner wall of the first cavity 3, a thread block 5 is provided inside the first cavity 3, the thread block 5 and the thread groove 4 are threadedly connected, a driving rotating rod 6 is provided outside the connecting pipe 2, the lower end of the driving rotating rod 6 is movably penetrated into the inside of the connecting pipe 2, a connecting rod 7 is provided on the outer surface of the driving rotating rod 6, a second cavity 8 is provided inside the connecting rod 7, the lower end of the driving rotating rod 6 is movably penetrated into the inside of the second cavity 8, a connecting disk 9 is sleeved on the outer surface of one end of the driving rotating rod 6 located inside the second cavity 8, a plurality of first engaging teeth 10 are provided on the upper surface of the connecting disk 9, a plurality of second engaging teeth 11 are provided on the upper surface of the second cavity 8, and the first engaging teeth 10 and the second engaging teeth 11 are meshingly connected.

[0023] Furthermore, a rotation groove 12 is formed on the bottom wall of the second cavity 8 , and a rotation disk 13 is rotatably connected inside the rotation groove 12 . A spring 14 is fixedly connected between the upper surface of the rotation disk 13 and the lower surface of the driving rotating rod 6 .

[0024] Furthermore, a sliding groove 16 is provided inside the connecting rod 7 , and the sliding groove 16 extends out of the connecting rod 7 . A connecting square rod 15 is slidably connected inside the sliding groove 16 , and the lower end of the connecting square rod 15 is fixedly connected to the upper surface of the threaded block 5 .

[0025] Furthermore, a stopper rod 17 is provided at the lower end of the threaded block 5. The stopper rod 17 is an existing mechanism, specifically the stopper rod used in the comparative example, and therefore will not be described in detail below.

[0026] Furthermore, a first sealing gasket 18 is sleeved on the outer surface of the connecting rod 7, a first sealing groove 19 is opened on the inner wall of the first cavity 3, the first sealing gasket 18 is rotatably connected to the inside of the first sealing groove 19, a second sealing gasket 20 is arranged on the lower surface of the first sealing gasket 18, a second sealing groove 21 is opened on the bottom wall of the first sealing groove 19, and the second sealing gasket 20 and the second sealing groove 21 are rotatably connected. The arrangement of the first sealing gasket 18, the first sealing groove 19, the second sealing gasket 20 and the second sealing groove 21 ensures the stability of the connecting rod 7, avoids the driving rotating rod 6 from causing the connecting rod 7 to move in the vertical direction, makes the connecting rod 7 only able to rotate, and also further improves the sealing performance of the connecting rod 7.

[0027] Furthermore, a third sealing gasket 22 is fixedly sleeved on the outer surface of the connecting rod 7, and the upper surface of the third sealing gasket 22 is fixedly connected to the top wall of the first cavity 3. The provision of the third sealing gasket 22 improves the sealing between the driving rotating rod 6 and the connecting pipe 2.

[0028] Working principle: the staff pulls the driving rod 6 upwards, and the driving rod 6 will move inside the second cavity 8. The sliding of the driving rod 6 drives the connection disk 9 to move. When the first engaging teeth 10 and the second engaging teeth 11 are in contact with each other on the upper surface of the connection disk 9, the driving rod 6 is rotated to drive the connection disk 9 to rotate until the first engaging teeth 10 and the second engaging teeth 11 are engaged. At this time, the spring 14 will be stretched, and the rotation of the connection disk 9 will drive the spring 14 to rotate. The spring 14 drives the rotating disk 13 to rotate inside the rotating groove 12. When the first engaging teeth 10 and the second engaging teeth 11 are engaged, the driving rod 6 continues to be rotated. At this time, the driving rod 6 will drive the connecting rod 7 to rotate synchronously. Rotation, the rotation of the connecting rod 7 drives the threaded block 5 to rotate. Because the threaded block 5 and the threaded groove 4 are threadedly connected, the threaded block 5 will be displaced, and the displacement of the threaded block 5 drives the connecting square rod 15 to slide inside the sliding groove 16. At this time, the connecting rod 7 will not move under the restriction of the first sealing gasket 18. The displacement of the threaded block 5 finally drives the movement of the blocking rod 17. When the staff releases the driving rotating rod 6, the elastic force of the spring 14 itself will pull down the driving rotating rod 6, and then the first engaging tooth 10 and the second engaging tooth 11 will no longer be engaged. When the driving rotating rod 6 is rotated subsequently, the driving rotating rod 6 will only drive the connecting disk 9 to idle inside the second cavity 8, thereby finally realizing the anti-mistouch function of the device.
