Description

Technical Field

[0001] The utility model relates to the technical field of heating engineering, in particular to a heating pipe orifice sealing rotating shaft. Background Art

[0002] The heating pipe orifice sealing shaft is a mechanical component used to seal the orifices of heating pipes. When the heating pipe is not in use or undergoing maintenance, the orifice needs to be effectively sealed to prevent heat loss, foreign matter intrusion, or leakage. The sealing shaft is usually made of a sturdy material, such as metal. Its working principle is similar to that of a rotatable lid or baffle. For example, during normal heating, the shaft can be rotated open to allow hot water or steam to pass smoothly through the pipe; when the pipe orifice needs to be sealed, the shaft rotates closed, tightly fitting the pipe orifice to achieve the sealing effect.

[0003] In the prior art, most heating pipe orifice sealing shafts are of an integral structure or multiple components are connected by bolt assemblies. Although the above-mentioned integral structure ensures the stability and sealing of the structure to a certain extent, once some components are damaged, they need to be replaced as a whole. If the above-mentioned multiple components are connected by bolt assemblies, when disassembling and replacing the damaged components, due to the small space in the pipeline, it is very unfavorable to use wrench-like tools, which will cause great trouble to the operator. In order to improve it, a heating pipe orifice sealing shaft is proposed. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a heating pipe orifice sealing shaft.

[0014] Beneficial effects of the utility model:

[0015] 1. The friction between the rotating block and the rotating port is large, which has a certain resistance and can prevent the baffle from spontaneously rotating open or close due to problems with the medium in the pipeline, thereby ensuring the stability of the pipe port sealing state.

[0016] 2. The cooperation between the sealing ring and the sealing groove ensures the sealing of the rotating block when it rotates in the rotating mouth, preventing the leakage of the medium in the pipeline.

[0017] 3. The cooperation between the positioning rod and the positioning groove makes it impossible for the rotating shaft body and the connecting groove to be separated under normal conditions, thereby ensuring the stability of the connection between the rotating shaft body and the rotating block.

[0018] 4. When disassembling the shaft body, the movable block is driven by lifting the movable frame to make the positioning rod disengage from the positioning groove, so that the shaft body and the connecting groove can be separated. The operation is convenient and the disassembly and maintenance of the shaft body are convenient. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0027] Reference Figure 1-6 A heating pipe orifice sealing shaft comprises a pipe 1, a baffle 2 and a shaft body 4, a rotating block 3 is provided on the baffle 2, a rotating port 7 is provided on the pipe 1, the rotating block 3 is arranged in the rotating port 7 through a sealing mechanism, a connecting groove 10 corresponding to the shaft body 4 is provided on the rotating block 3, a movable cavity 12 is provided inside the shaft body 4, a movable block 13 is provided in the movable cavity 12 through a vertical elastic mechanism, a movable frame 6 is mounted on the movable block 13, a sliding rod 17 is provided in the movable cavity 12, a connecting plate 16 is provided on the sliding rod 17 through a transverse elastic mechanism, and the connecting plate 16 cooperates with the connecting groove 10 through a positioning mechanism.

[0028] The sealing mechanism includes a sealing ring 9 arranged outside the rotating block 3, and a sealing groove 8 corresponding to the sealing ring 9 is provided on the arc-shaped inner wall of the rotating opening 7. The sealing ring 9 fits in the sealing groove 8 to ensure the sealing of the rotating block 3 when rotating in the rotating opening 7.

[0029] The elastic mechanism includes a vertical spring 14 arranged in the movable cavity 12. The two ends of the vertical spring 14 are elastically connected to the outer wall of the movable block 13 and the inner wall of the movable cavity 12 respectively. The vertical spring 14 can be reset when the movable block 13 moves due to external force and the external force is lost.

[0030] The transverse elastic mechanism includes a transverse spring 18 sleeved on the outside of the slide rod 17. The two ends of the transverse spring 18 are elastically connected to the outer walls of the two connecting plates 16 respectively. The transverse spring 18 can be reset when the connecting plates 16 move under external force and the external force is no longer involved.

[0031] The positioning mechanism includes a positioning rod 15 installed on the connecting plate 16. The positioning rod 15 slides through the inner wall of the movable cavity 12 and extends to the outside of the rotating shaft body 4. A positioning groove 11 corresponding to the positioning rod 15 is provided on the arc-shaped inner wall of the connecting groove 10. When the positioning rod 15 is in the positioning groove 11, the rotating shaft body 4 cannot be separated from the connecting groove 10.

[0032] The movable frame 6 is designed in a T-shape, and the vertical spring 14 is arranged outside the vertical part of the movable frame 6. The T-shape design is convenient for the finger part of the hand to hang on it, so as to apply external force to lift it up.

[0033] The surfaces where the movable block 13 and the positioning rod 15 contact each other are tilted, and the surfaces where the movable block 13 and the positioning rod 15 contact each other are polished. Only by tilting them can the positioning rod 15 move horizontally when the movable block 13 is raised or lowered.

[0034] A handle 5 is mounted on the shaft body 4 , and a rubber protective sleeve is provided on the handle 5 . The handle 5 is in contact with the palm of the hand, and the rubber protective sleeve protects the hand.

[0035] During use, when the present invention needs to rotate the shaft body 4 to drive the baffle 2 to close or open the pipe opening, a rotational force is applied via the handle 5. The handle 5 drives the shaft body 4 to rotate, thereby rotating the baffle 2. During this rotation, the rotating block 3 rotates within the rotating opening 7. The sealing ring 9 and the sealing groove 8 ensure a tight seal during rotation. Furthermore, the friction between the rotating block 3 and the rotating opening 7 is relatively high, providing a certain resistance, preventing the baffle 2 from spontaneously opening or closing due to problems with the medium in the pipe 1.

[0036] Under normal conditions, positioning rod 15 is located within positioning groove 11, preventing the shaft body 4 from separating from the engagement groove 10 and ensuring the stability of the connection between the shaft body 4 and the rotating block 3. To disassemble the shaft body 4, place your palm on handle 5, hook your fingers around the movable frame 6, and lift upward, thereby lifting the movable block 13 upward through the movable frame 6. Because the contact surface between the movable block 13 and positioning rod 15 is inclined and polished, when the movable block 13 moves upward, the positioning rod 15, under the action of the engagement plate 16 and the transverse spring 18, moves, allowing the positioning rod 15 to disengage from the positioning groove 11, at which point the shaft body 4 can be separated from the engagement groove 10.

[0037] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
