Description

Technical Field

[0001] This utility model relates to the field of de-cooling and de-pressure devices, and in particular to an integrated annular nozzle de-cooling and de-pressure device. Background Technology

[0002] A large-diameter, small-flow desuperheating and pressure-reducing device is a device used to control and regulate the temperature and pressure of steam or other gases. It is mainly used in power, chemical, and petroleum industries to desuperheat and reduce the pressure of fluids in pipeline systems, ensuring the safe and stable operation of the system. When desuperheating and reducing the pressure of steam or other gases flowing in pipelines, nozzles and pressure regulating valves are usually installed directly on the pipeline. The pressure regulating valve can directly regulate the internal pressure of the pipeline, that is, by adjusting the opening of the valve, the pressure of the fluid is reduced.

[0003] When installing nozzles on fluid transport pipelines, multiple nozzles are usually installed in a ring array outside the pipeline. The nozzles are usually installed to the pipeline by threaded connection, directly threading the nozzles onto the pipeline. However, as the pipeline transports fluid and the nozzles spray cooling water, the pipeline and nozzles will vibrate. Vibration will occur at the connection between the nozzle and the pipeline, and the nozzle connection may become loose, thereby reducing the stability of the nozzle installation and use.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] This utility model provides, for example Figure 1-4 The integrated annular nozzle de-cooling and pressure-reducing device shown includes a delivery pipe 1, on which a regulating valve 2 is installed. The regulating valve 2 uses a multi-stage throttling method to regulate the pressure of the fluid inside the delivery pipe 1, avoiding the noise and vibration problems caused by single-stage throttling, while ensuring the stability of the fluid. A flange pipe 3 is installed on the delivery pipe 1, and mounting blocks 4 are fixedly connected to the outside of the flange pipe 3 in an annular array. The mounting blocks 4 have threaded holes, and the flange pipe 3 has holes communicating with the threaded holes. A nozzle component 5 is threadedly fitted into the inner cavity of the threaded hole. The nozzle component 5 is connected to an external cooling water delivery pump through a pipe, so that the delivery pump can... Cooling water is sprayed into the interior of the delivery pipe 1 through the pipe and nozzle 5. A locking component 6 for positioning the nozzle 5 is provided on one side of the mounting block 4. The locking component 6 includes a locking plate 61, a positioning collar 62 and a positioning plate 63. The locking plate 61 is horizontally slidably disposed on one side of the mounting block 4. The positioning collar 62 is fixedly sleeved on the outside of the nozzle 5. The positioning plate 63 is snapped between the positioning collar 62 and the locking plate 61. The positioning plate 63 is snapped between the positioning collar 62 and the locking plate 61, so that the nozzle 5 can be locked by snapping the positioning collar 62 to prevent the nozzle 5 from rotating and reduce the possibility of the nozzle 5 becoming loose.

[0024] In particular, a sealing gasket is connected to the bottom of the positioning collar 62. The bottom of the sealing gasket is pressed and fitted against the mounting block 4. The sealing gasket can improve the sealing performance at the connection between the positioning collar 62 and the mounting block 4 on the outer wall of the nozzle component 5. A positioning groove is provided on one side of the positioning collar 62. One end of the outer wall of the positioning plate 63 is slidably engaged with the inner cavity of the positioning groove. When the positioning plate 63 is engaged with the positioning groove, it can also limit the positioning plate 63 and prevent the positioning plate 63 from moving up and down. A slot 64 is provided on the top of one side of the locking plate 61. The other end of the outer wall of the positioning plate 63 is slidably engaged with the inner cavity of the slot 64. A through hole is provided on one side of the positioning plate 63. A connecting shaft 65 is slidably engaged in the inner cavity of the through hole. A sliding groove 66 is provided on the inner wall of the slot 64. The outer wall of the connecting shaft 65 is... The end of the positioning plate 63 is slidably engaged with the inner cavity of the groove 66. The positioning plate 63 can move up and down relative to the locking plate 61 via the connecting shaft 65, thereby positioning the positioning plate 63 at the corresponding height to engage and lock the positioning collar 62. Under the action of the connecting shaft 65, the locking plate 61 can also limit the positioning plate 63, preventing the positioning plate 63 from rotating in the vertical direction, thus ensuring the stability of the positioning plate 63 locking the positioning collar 62. Pulling the locking plate 61 away from the positioning collar 62 separates the positioning plate 63 from the positioning collar 62. Then, the positioning plate 63 can drive the connecting shaft 65 to slide and separate from the locking plate 61, thereby releasing the limitation on the positioning collar 62, which facilitates the subsequent installation or disassembly of the nozzle component 5.

[0025] Furthermore, a fixing rod 67 is symmetrically arranged on the side of the locking plate 61 facing the mounting block 4. A limit spring 69 is slidably sleeved on the outer wall of the fixing rod 67. A fixing bolt 68 is arranged on the side of the locking plate 61 away from the mounting block 4. The fixing rod 67 is fixedly connected to the locking plate 61 through the fixing bolt 68. Mounting holes are symmetrically opened on one side of the mounting block 4. The inner cavity of the mounting hole is not connected to the inner cavity of the threaded hole. A fixing collar 610 is fixedly sleeved on one end of the inner cavity of the mounting hole. The outer wall of the fixing rod 67 is slidably sleeved with the fixing collar 610. The end of 7 is fixedly connected to a limiting block 611. The limiting spring 69 is located between the limiting block 611 and the fixing collar 610. The limiting spring 69 can give the locking plate 61 a spring force in the direction of the mounting block 4 through the limiting block 611 and the fixing rod 67, thereby ensuring the stability of the locking plate 61 driving the positioning plate 63 to engage with the positioning collar 62. By removing the fixing bolt 68, the fixing rod 67 on one side of the locking plate 61 can be disassembled, thereby directly disassembling and maintaining the locking plate 61, fixing rod 67 and limiting spring 69 on the mounting block 4.

[0026] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
