Description

Technical Field

[0001] The utility model relates to the technical field of valves, in particular to a valve stem cooling mechanism for a high-temperature and high-pressure valve. Background Art

[0002] High temperature and high pressure valve is an automatic pressure relief protection device opened by the imported static pressure. It is one of the most important safety accessories of pressure vessels. Its function is that when the pressure in the container exceeds a certain value, the high temperature valve automatically opens the valve by relying on the pressure of the medium itself, and the high temperature valve quickly discharges a certain amount of medium.

[0003] However, in the prior art, the traditional cooling mechanism only cools the valve stem during use, while the valve body is also in a high-temperature state. The valve stem works in the valve body, which makes the valve stem alternately hot and cold, thereby affecting the service life of the valve stem. In addition, traditional equipment is usually fixed and used in a high-temperature environment. When the cooling mechanism fails, the staff cannot quickly disassemble and assemble the cooling mechanism, and long-term operation in a high-temperature environment will cause discomfort to the staff.

The outer wall of the main shell 2 is fixedly connected with an air pipe, and the end of the air pipe away from the main shell 2 is connected to the main shell 2 at the blade 76, so that when the blade 76 rotates, wind can be blown into the main shell 2 through the air pipe, thereby blowing the hot air in the main shell 2 out of the main shell 2. The inner wall of the heat conductive sheet 21 is fixedly connected with a heat dissipation net 22, and is arranged in a ring array along the central axis of the heat conductive sheet 21.

[0039] The inner wall of the heat conducting plate 21 contacts the outer wall of the valve body 1, the inner wall of the main shell 2 is slidably connected to the outer wall of the valve stem body 3, the outer wall of the valve stem body 3 is slidably connected to the inner wall of the auxiliary shell 5, the bottom of the auxiliary shell 5 is fixedly connected to the bottom of the main shell 2 through the connecting pipe 8, and the end of the connecting pipe 8 away from the auxiliary shell 5 is fixedly connected to the bottom of the main shell 2, the fixing mechanism 6 includes a fixing plate 67, the outer wall of the fixing plate 67 is fixedly connected with a clamping block 63, the inner wall of the top of the clamping block 63 is slidably connected with a push plate 65, the outer wall of the push plate 65 is fixedly connected with a top spring 66, the push plate 65 is driven to move by the top spring 66, and then the push plate 65 pops the main shell 2 and the auxiliary shell 5 apart, the outer wall of the clamping block 63 is clamped with the inner wall of the buckle plate 64, the outside of the clamping block 63 is provided with a fixing block 62, the inner wall of the top of the fixing block 62 is slidably connected with a pressure plate 61.

[0041] Working principle:

[0042] When in use, first open the main shell 2 and the sub-shell 5 to make the main shell 2 and the sub-shell 5 in an expanded state, then wrap the main shell 2 on the valve body 1, and then rotate the sub-shell 5 to close the main shell 2 and the sub-shell 5 and wrap the valve body 1 and the valve stem body 3 inside. During the closing process of the main shell 2 and the sub-shell 5, the fixing mechanism 6 is locked, thereby locking the position of the main shell 2 and the sub-shell 5, and then pour refrigerant into the main shell 2 through the water inlet pipe 4 on the main shell 2. After the main shell 2 and the sub-shell 5 are completely filled with refrigerant, stop pouring refrigerant, and then close the water inlet pipe 4 to prevent the refrigerant from flowing out of the water inlet pipe 4. At this time, the air cooling mechanism 7 can be started to cool the valve stem body 3.

[0043] During the process of cooling the valve stem body 3 by the air cooling mechanism 7, the heat generated by the valve body 1 during operation is first transferred to the main housing 2 through the heat conducting sheet 21, and the heat is transferred to the refrigerant in the main housing 2, while the heat dissipation net 22 in the heat conducting sheet 21 is used to transfer part of the heat in the heat conducting sheet 21 to the air. At the same time, the brushless motor 75 in the air cooling mechanism 7 drives the blade 76 to rotate, and the brushless motor 75 is fixed to the main housing 2 through the frame 73, so as to support the position of the brushless motor 75. During the rotation of the blade 76, wind force is generated, thereby cooling the heat conducting disk 74. A heat conducting plate 71 is provided in the main housing 2, and a heat sink 72 is fixed on the heat conducting plate 71. The contact area with the refrigerant is increased by the heat sink 72 and the heat conducting plate 71, so that the heat carried in the refrigerant enters the heat conducting disk through the heat conducting plate 71. On the main shell 2 at 74, a conduction block 77 is fixed between the main shell 2 and the heat conducting plate 74, and the conduction block 77 adopts a honeycomb plate shape to increase the contact area between the conduction block 77 and the air, so that part of the heat can be dissipated into the air during the process of passing through the conduction block 77. The heat on the main shell 2 is conducted to the heat conducting plate 74 through the conduction block 77, so that the wind force generated by the blades 76 can continuously dissipate the heat from the heat conducting plate 74, thereby maintaining the temperature of the refrigerant in the shell. The main shell 2 and the auxiliary shell 5 are connected by a connecting pipe 8, so that the refrigerant between the main shell 2 and the auxiliary shell 5 can circulate with each other, thereby maintaining the temperature between the main shell 2 and the auxiliary shell 5 consistent, and the heat dissipation fins 23 transfer the temperature in the refrigerant to the main shell 2 attached to the valve stem body 3, thereby cooling the valve stem body 3.

[0044] After the cooling mechanism is used, it is only necessary to press the pressure plate 61 in the fixed block 62 to make the pressure plate 61 slide downward and then press the top of the card block 63, so that the card block 63 withdraws from the inner wall of the buckle plate 64 and contacts the buckle plate 64 to lock the card block 63. When the card block 63 slides out of the buckle plate 64, the push plate 65 pushes the buckle plate 64 under the elastic action of the top spring 66, and the top spring 66 is fixed on the fixed plate 67, so a reaction force is generated on the fixed plate 67, thereby popping open the secondary shell 5, thereby reducing the work intensity of the staff. When the main shell 2 and the secondary shell 5 are installed again, the card block 63 is re-engaged in the buckle plate 64, and under the push of the buckle plate 64, the push plate 65 compresses the top spring 66 during the sliding process, so that the top spring 66 has the force to pop open the secondary shell 5 again.
