Abstract
Description
Technical Field
[0001] The present application relates to an air drying device, and in particular to a circulating air drying device. Background Art
[0002] At present, two-piece ball valves are usually dried in an oven after cleaning. Although traditional ovens can quickly dry such valves, since the gaskets of such ball valves are mostly polytetrafluoroethylene gaskets, they are easily deformed after being dried in the oven at high temperature for a long time, which causes the valve to leak internally and greatly shortens the service life of the valve. Therefore, a utility model is needed to provide a drying device that can efficiently dry the valve without affecting the service life of the valve. Utility Model Content

[0009] Preferably, in the above-mentioned circulating air drying device, the filler plate is a push-pull filler plate, and the color-changing silica gel is evenly laid.
[0010] Preferably, in the above-mentioned circulating air drying device, the air supply port is connected to nitrogen.
[0011] Preferably, in the above-mentioned circulating air drying device, a two-piece ball valve to be dried is laid on the storage plate.
[0012] Compared with the prior art, the advantages of the utility model are:
[0013] 1. By connecting nitrogen for air drying, the valve can be dried at low temperature, which greatly increases the service life of the two-piece ball valve;
[0014] 2. By installing multiple packing plates, multi-stage drying of the circulating gas is achieved, ensuring the air-drying effect of the two-piece ball valve. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The following will be combined with the drawings in the embodiments of the utility model to describe the technical solutions in the embodiments of the utility model in detail. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of 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.
[0019] Combination Figure 1-2 As shown, the circulating air drying device 100 comprises a drying chamber 101 and an air inlet chamber 102 which are arranged opposite to each other in the upper and lower parts. The bottom of the drying chamber 101 is sealed and connected to the top of the air inlet chamber 102 and an axial flow fan 103 is arranged therebetween. The two sides of the drying chamber 101 and the two sides of the air inlet chamber 102 are respectively connected to circulating air ducts 104. An exhaust port 105 is provided at the top of the drying chamber 101, and an air supply port 106 is provided at one side of the air inlet chamber 102. A horizontally arranged storage plate 107 is installed inside the drying chamber 101. A horizontally arranged packing plate 108 is installed inside the drying chamber 101 below the storage plate 107. A horizontally arranged packing plate 108 is installed inside the air inlet chamber 102. Horizontally arranged packing plates 108 are respectively installed inside the two circulating air ducts 104. The packing plates 108 are push-pull type packing plates, and color-changing silica gel is evenly laid. The air supply port 106 is connected to nitrogen. A two-piece ball valve to be dried is placed on the storage plate 107 .
[0020] When implementing it specifically,
[0021] 1. Connect the gas supply port to the nitrogen source and adjust the exhaust port connection valve to 1 / 4;
[0022] 2. Take out the packing plate in the device and evenly lay the color-changing silica gel (to absorb the moisture in the device and facilitate the observation of the humidity in the device);
[0023] 3. Place the two-piece ball valve to be dried evenly on the storage plate and cover it with the top cover;
[0024] 4. Adjust the nitrogen flow rate to 25 L / min, turn on the axial flow fan, accelerate the circulation of gas in the circulating air drying device, and blow nitrogen for 6 hours to complete the drying. The two circulating air ducts, while maintaining the stable balance of wind pressure in the device, carry out multi-stage drying of the circulating gas in the device through the filler installed in the middle;
[0025] 5. After drying is completed, turn off the axial flow fan and nitrogen in turn, remove the valve, and check the internal packing.
[0026] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.
