Technical Field
[0001] The utility model relates to a steam pipeline pressure regulating device, belonging to the technical field of pipeline pressure regulating. Background Art
[0002] As the name implies, pressure regulation is the regulation of pressure. In many structures, in order to ensure the normal operation and movement of the structure, it is necessary to regulate the internal pressure to ensure the working safety of the equipment and structure. The pipeline is a device connected by pipes, pipe connectors and valves for conveying gas, liquid or fluid with solid particles. When used in gas pipelines, it is necessary to regulate the gas pressure in the pipeline to avoid the situation where the pipeline ruptures due to gas overpressure. It is necessary to apply a pipeline pressure regulating device. The existing steam pipeline pressure regulating device usually adjusts the position of the block inside the pipeline to control the gas flow rate to achieve the purpose of pressure regulation. However, a single block does not have a buffering function. When the internal pressure of the pipeline suddenly increases, the equipment is prone to damage. Now there is an urgent need for a steam pipeline pressure regulating device to solve the above problems. Utility Model Content

[0004] In order to achieve the above-mentioned purpose, the utility model is implemented through the following technical scheme: a steam pipe pressure regulating device, including a connecting seat, a connecting flange, a limit seat, a threaded sleeve, a pressure regulating block, a first rotating member, a second rotating member and an extrusion spring, the connecting seat is symmetrically welded with connecting flanges at both ends, the upper end of the outer surface of the connecting seat is welded and fixed with a limit seat, a threaded sleeve is embedded in the central position of the upper end surface of the limit seat, a pressure regulating block is movably arranged inside the connecting seat, a first rotating member is arranged inside the pressure regulating block, a second rotating member is arranged inside the first rotating member, and an extrusion spring is arranged on the lower end surface of the second rotating member.
[0005] Furthermore, a first spring seat is fixed inside the pressure regulating block, a second spring seat is provided on the lower end surface of the second rotating member, and two ends of the extrusion spring are fixedly connected to the first spring seat and the second spring seat respectively.

[0010] Beneficial effects of the utility model: A steam pipeline pressure regulating device of the utility model is provided.

DETAILED DESCRIPTION
[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.
[0019] See also Figure 1-Figure 5 The utility model provides a technical solution: a steam pipeline pressure regulating device, including a connecting seat 1, a connecting flange 2, a limiting seat 3, a threaded sleeve 4, a pressure regulating blocking block 5, a first rotating member 6, a second rotating member 7 and an extrusion spring 8. The connecting seat 1 is symmetrically welded with connecting flanges 2 at both ends, the limiting seat 3 is welded and fixed at the upper end of the outer surface of the connecting seat 1, and the threaded sleeve 4 is embedded in the central position of the upper end surface of the limiting seat 3. A pressure regulating blocking block 5 is movably arranged inside the connecting seat 1, a first rotating member 6 is arranged inside the pressure regulating blocking block 5, a second rotating member 7 is arranged inside the first rotating member 6, and an extrusion spring 8 is arranged on the lower end surface of the second rotating member 7. This design solves the problem that the original steam pipeline pressure regulating device cannot well cope with the pressure change inside the pipeline.
[0020] As the first embodiment of the utility model: a first spring seat 51 is fixed inside the pressure regulating block 5, and a second spring seat 72 is arranged on the lower end surface of the second rotating member 7. Both ends of the extrusion spring 8 are fixedly connected to the first spring seat 51 and the second spring seat 72 respectively. The first spring seat 51 and the second spring seat 72 can effectively connect the two ends of the extrusion spring 8 to the pressure regulating block 5 and the second rotating member 7 respectively. This design can effectively prevent the extrusion spring 8 from being offset or falling off during the process of being squeezed or releasing elastic potential energy. A limiting block 61 is arranged on the lower end of the outer side surface of the first rotating member 6. The limiting block 61 slides tightly along the inner wall of the pressure regulating block 5. The limiting block can limit the position between the first rotating member 6 and the pressure regulating block 5, thereby preventing the first rotating member 6 from being separated from the pressure regulating block 5. At the same time, the first rotating member 6 can be inside the pressure regulating block 5. The first rotating member 6 is freely rotated, an internal thread 62 is provided on the inner wall of the first rotating member 6, and an adjusting thread 73 is provided on the outer side of the second rotating member 7. The internal thread 62 and the adjusting thread 73 are meshed with each other. The meshing between the internal thread 62 and the adjusting thread 73 allows the second rotating member 7 to move in the vertical direction relative to the rotation of the first rotating member 6. An external thread 63 is provided on the outer side of the first rotating member 6, and the external thread 63 and the threaded sleeve 4 are meshed with each other. The meshing between the external thread 63 and the threaded sleeve 4 allows the first rotating member 6 to move in the vertical direction relative to the rotation of the threaded sleeve 4. A first rotating handle 64 is welded and fixed on the outer side of the first rotating member 6. The first rotating handle 64 is convenient for users to rotate the first rotating member 6. A second rotating handle 71 is welded and fixed on the upper end surface of the second rotating member 7. The second rotating handle 71 is convenient for users to rotate the second rotating member 7.
[0021] As a second embodiment of the present invention: the user connects the two ends of the connecting seat 1 to the external steam pipeline through the connecting flange 2. When the pressure inside the steam pipeline needs to be adjusted, the user can drive the first rotating member 6 to rotate through the first turning handle 64. Since the external thread 63 and the threaded sleeve 4 are meshed with each other, the rotation of the first rotating member 6 can move itself in the vertical direction through the threaded sleeve 4, thereby driving the pressure regulating block 5 to move closely along the inner wall of the limiting seat 3, so that the cross-sectional area of the current position inside the connecting seat 1 changes, thereby changing the flow rate of steam inside the connecting seat 1, so as to achieve the purpose of adjusting the pressure. When the steam pressure changes, for example, the pressure inside the connecting seat 1 suddenly increases, the pressure regulating block 5 will move upward along the surface of the first rotating member 6 and compress the extrusion spring 8. The sudden increase in pressure is buffered by the reserved buffer space and the extrusion spring 8 to prevent the pipeline from being damaged and bursting. The user can also rotate the second rotating member 7 alone through the second turning handle 71, so that the second rotating member 7 moves vertically along the inside of the first rotating member 6 under the action of the internal thread 62 and the adjusting thread 73, and drives the second spring seat 72 to compress the extrusion spring 8. By adjusting the elastic force of the extrusion spring 8, its buffering capacity can be adjusted.
