Description

Technical Field

[0001] The utility model relates to the technical field of plate heat exchangers, in particular to a cold preservation device for valves of plate heat exchangers. Background Art

[0002] A plate heat exchanger is a highly efficient heat exchange device that transfers heat through a series of parallel metal plates. When the connecting end of the plate heat exchanger is connected to the pipeline, a valve must be installed on the surface of the pipeline.

[0003] After the existing valve is connected to the pipeline, it is necessary to wrap the valve surface with insulation cotton. The insulation cotton can keep the valve cold. When the insulation cotton wraps the valve, glue is needed at the joints of the two to ensure that the insulation and the valve are firmly connected. However, when the insulation cotton needs to be replaced, the insulation cotton needs to be torn off, resulting in a large amount of insulation cotton remaining on the valve surface, which is inconvenient for the next wrapping of the insulation cotton. Therefore, it is necessary to propose a valve cold preservation device that is easy to replace. Utility Model Content

[0040] The cold insulation component includes a heat preservation cotton 21, a connection frame 22, a docking plate 23, and a set of limit rods 24;

[0041] The insulation cotton 21 is sleeved on the surface of the valve 14, the connecting frame 22 is fixed to one side of the opening below the insulation cotton 21, and the docking plate 23 is fixed to the other side of the opening below the insulation cotton 21. The limiting rod 24 passes through the connection between the connecting frame 22 and the docking plate 23;

[0042] The heat preservation cotton 21 is used to keep the valve 14 cold, the connecting frame 22 and the docking plate 23 are used to connect the heat preservation cotton 21, and the limit rod 24 is used to connect the connecting frame 22 and the docking plate 23;

[0043] The limiting rod 24 is provided with a limiting hole 25 at the connection between the connecting frame 22 and the docking plate 23, and the limiting rod 24 is threadedly connected to the inside of the limiting hole 25;

[0044] The limiting hole 25 is provided for the insertion and connection of the limiting rod 24. The limiting rod 24 rotates into the limiting hole 25, so that the connecting frame 22 and the docking plate 23 are firmly connected, so that the thermal insulation cotton 21 wraps the surface of the valve 14;

[0045] A set of docking rods 26 are fixedly connected to one side of the inner portion of the connection frame 22, and a set of docking grooves 27 are opened on one side of the docking plate 23, and the docking rods 26 are clamped into the inner portion of the docking grooves 27;

[0046] The docking rod 26 is used to connect the connecting frame 22 and the docking plate 23, and the docking groove 27 is used to insert the docking rod 26. The docking rod 26 is inserted into the docking groove 27 to strengthen the connection between the connecting frame 22 and the docking plate 23;

[0047] Working principle:

[0048] The staff manually wraps the insulation cotton 21 on the surface of the valve 14, and then inserts the docking plate 23 into the connecting frame 22, so that the insulation cotton 21 wraps the valve 14. When the docking plate 23 is inserted into the connecting frame 22, the docking rod 26 is inserted into the docking groove 27, thereby reinforcing the docking rod 26 to stabilize the connection between the connecting frame 22 and the docking plate 23;

[0049] Then the staff manually inserts the limiting rod 24 into the limiting hole 25 and rotates the limiting rod 24 so that the limiting rod 24 gradually enters the limiting hole 25 of the connecting frame 22 and the docking plate 23, thereby limiting the connection between the connecting frame 22 and the docking plate 23, thereby allowing the thermal insulation cotton 21 after connection to better wrap the valve 14 and keep it cool.

[0050] In the above steps, the thermal insulation cotton 21 keeps the valve 14 cool through the interaction between the thermal insulation cotton 21, the connecting frame 22 and the docking plate 23.

[0051] See also Figure 1 、 Figure 6-Figure 7 As shown, this embodiment is based on the above embodiment 1 and also includes:

[0052] Anti-loosening components;

[0053] The anti-loosening assembly includes a limiting ring 31, a set of connecting plates 32, and a guide ring 33;

[0054] The limiting ring 31 is sleeved on the outer end of the rod surface of the bolt 15, the connecting plates 32 are fixed on both sides of the limiting ring 31, and the guide ring 33 is fixed on the outer end of the connecting plate 32;

[0055] The limiting ring 31 limits the position of the nut, the connecting plate 32 is used to connect the limiting ring 31 and the guide ring 33, and the guide ring 33 is used to connect the guide rod 34;

[0056] A guide rod 34 is passed through the inner side of the guide ring 33, and the inner end of the guide rod 34 is fixedly connected to the pipe 13 and the valve 14;

[0057] A spring 35 is fixedly connected between the guide ring 33 and the pipe 13 and the valve 14. A plug rod 36 is fixedly connected to the inner side of the limit ring 31. One end of the plug rod 36 passes through the nut.

[0058] The guide rod 34 is used to guide the movement of the ring 33. The force between the springs 35 is such that when the nut is loose, the limit ring 31 squeezes the nut through the tension between the springs 35 and the plug-in rod 36 to prevent the nut from being excessively loosened.

[0059] The main assembly also includes a heat exchanger 11 and a set of connection ends 12;

[0060] The connection ends 12 are fixed to one end of the heat exchanger 11, and the pipes 13 are fixed to the outer ends of the connection ends 12;

[0061] The heat exchanger 11 converts water into hot and cold water. The connection end 12 is used to connect the pipe 13. There are four connection ends 12 in total.

[0062] Working principle:

[0063] During use, the staff pulls the limit ring 31 by hand, and the limit ring 31 moves outward through the connecting plate 32 and the guide ring 33. At this time, the guide ring 33 moves on the guide rod 34, so that the limit ring 31 leaves the surface of the screw. Then, the nut is rotated to the connection point between the pipe 13 and the valve 14 to stop.

[0064] Then, the limiting ring 31 is sleeved on the screw rod. Due to the performance of the spring 35, the spring 35 drives the limiting ring 31 to move to its original position through the guide ring 33 and the connecting plate 32, so that the plug rod 36 is inserted into the nut. The limiting ring 31 squeezes the nut through the tension between the spring 35 and the plug rod 36 to prevent the nut from loosening.
