Description

Technical Field

[0001] The utility model relates to the technical field of flue valves, in particular to a flue quick-opening valve with a cooling device. Background Art

[0002] A quick-opening flue valve is a special valve design primarily used in flue systems, capable of rapid opening and closing to control the flow of flue gases. Manually controlled by a mechanical device such as a handle or gear, the valve opens and closes rapidly. Some quick-opening valves incorporate a spring mechanism. When the valve is open, the spring rapidly tightens to maintain the valve open; when closing is desired, the spring releases energy, rapidly closing the valve. Quick-opening flue valves are widely used in the coal chemical industry, petrochemical industry, power plants, industrial furnaces, and other fields. The cooling device is a crucial component of quick-opening flue valves.

[0003] For example, the Chinese patent "A quick-opening flue plug-in door" with announcement number CN207584798U includes a door body, an inner bottom wall of the door body is fixedly connected to a first fixed plate, a movable groove is provided on the front of the first fixed plate, a first movable plate is movably connected between the left and right inner walls of the door body, a second movable plate is overlapped on the top of the first movable plate, the inner top wall of the door body is fixedly connected to a second fixed plate, a movable groove is provided on the front of the second fixed plate, and an auxiliary groove is provided on the left inner wall of the door body; the left side of the door body is fixedly connected to a power box.

[0004] Although the above-mentioned existing technology can realize the quick opening of the flue valve, in actual use, on the one hand, the flue quick-opening valve is difficult to cool down. Usually, the flue quick-opening valve is used in industrial flues, and the flue gas transported in the flue is generally at a high temperature, resulting in direct contact of the high-temperature flue gas with the valve body, causing the valve temperature to rise, thereby affecting the performance of the valve. On the other hand, the cooled coolant is difficult to cool down. After the coolant is transported back to the water tank, it is pumped out again by the water pump to cool the valve body, thereby reducing the cooling effect. Therefore, it does not meet the existing needs. In this regard, we propose a flue quick-opening valve with a cooling device. Utility Model Content

[0005] The purpose of the utility model is to provide a flue quick-opening valve with a cooling device to solve the problems in the above background technology that the flue quick-opening valve is difficult to cool and the cooling liquid after cooling is difficult to cool.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a flue quick-opening valve with a cooling device, comprising a valve body; and further comprising:

[0007] A chute is provided in the middle of the valve body, a valve plate is provided inside the chute, and the valve plate and the chute are slidably engaged, and heat pipes are provided at the front and rear ends of the valve plate, the heat pipes are distributed in an alternating bend, and the upper and lower ends of the heat pipes extend to the outside of the valve plate;

[0008] A cooling cavity is arranged inside the side wall of the valve body. Five cooling pipes are fixedly arranged inside the cooling cavity, and the cooling pipes are distributed at equal distances.

[0009] Preferably, a liquid separation box is fixedly provided above one side of the exterior of the valve body, and the liquid separation box is communicated with the cooling pipe. A liquid inlet pipe is fixedly provided on one side of the liquid separation box, and the liquid inlet pipe is communicated with the liquid separation box.

[0010] Preferably, a liquid collecting box is fixedly provided above the other side of the exterior of the valve body, and the liquid collecting box is communicated with the cooling pipe. A liquid outlet pipe is fixedly provided on one side of the liquid collecting box, and the liquid outlet pipe is communicated with the liquid collecting box.

[0011] Preferably, a ventilation groove is provided at the lower part of the valve body, and the ventilation groove is communicated with the cooling cavity.

[0012] Preferably, a motor is provided inside the ventilation slot, and four mounting rods are fixedly provided outside the motor. The mounting rods are distributed equidistantly in a ring shape, and the other ends of the mounting rods are fixedly connected to the valve body.

[0013] Preferably, the motor is located inside the ventilation slot and has fan blades fixedly provided outside the output shaft.

[0014] Preferably, a mounting seat is fixedly provided on the upper end of the exterior of the valve body, a storage cavity is provided inside the mounting seat, and the storage cavity is connected to the slide groove, a hydraulic telescopic device is fixedly provided on the upper end of the mounting seat, and the telescopic end of the hydraulic telescopic device extends to the interior of the storage cavity and is fixedly connected to the valve plate.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. The utility model can cool down the valve body and the valve through the heat pipe and the cooling pipe. When the cooling operation is performed, the external water pump is turned on first to make the water pump draw the coolant in the water tank. At this time, the coolant flows into the liquid separation box through the liquid inlet pipe, and then the coolant is diverted to the cooling pipe by the liquid separation box. At this time, the coolant with lower temperature absorbs the heat on the valve body and is finally discharged from the liquid outlet pipe. The valve body is cooled by the coolant. At this time, the valve plate is directly in contact with the high-temperature flue gas and is cooled by the heat pipe inside the valve plate. At this time, the liquid inside the heat pipe inside the valve plate vaporizes from the liquid state and moves to the upper and lower ends of the heat pipe, and the upper and lower ends of the heat pipe are not in direct contact with the flue gas, so that the heat on the valve plate is transferred to the upper and lower ends of the heat pipe. At this time, the heat on the heat pipe is transferred to the valve body in the form of thermal radiation, thereby improving the cooling effect.

[0017] 2. The utility model can cool the coolant through the ventilation slots and fan blades. When the cooling operation is carried out, the motor is turned on so that the output shaft of the motor drives the fan blades to rotate. At this time, the air near the fan blades flows and forms an airflow. The airflow generated by the fan blades blows toward the cooling pipe. At this time, the coolant in the cooling pipe transfers heat to the cooling pipe wall. The airflow cools the cooling pipe wall and the coolant together with it. The cooled coolant flows back to the water tank through the liquid collecting box and the liquid outlet pipe, avoiding the cooled coolant from being directly extracted, thereby improving the cooling effect.

[0018] 3. The utility model is provided with a hydraulic telescopic device, which can quickly open and close the valve plate. When the valve plate needs to be closed, the hydraulic telescopic device is turned on at this time, so that the telescopic end of the hydraulic telescopic device extends and drives the valve plate to move downward in the slide until the valve plate completely covers the valve body through-hole. At this time, the valve body is sealed. When the valve plate needs to be opened, the hydraulic telescopic device is turned on at this time, so that the telescopic end of the hydraulic telescopic device contracts and drives the valve plate to move upward in the slide until the valve plate exposes the valve body through-hole. At this time, the smoke passes through the valve body through the through-hole, which simplifies the closing method of the valve plate, thereby improving the opening and closing efficiency of the valve plate.

[0028] During use, when cooling operation is performed, the external water pump is first turned on to allow the water pump to extract the coolant in the water tank. At this time, the coolant flows into the liquid separation box 5 through the liquid inlet pipe 6, and then the liquid separation box 5 diverts the coolant to the cooling pipe 12. At this time, the coolant with lower temperature absorbs the heat on the valve body 1, and is finally discharged from the liquid outlet pipe 8. The valve body 1 is cooled by the coolant. At this time, the valve plate 4 is directly in contact with the high-temperature flue gas, and the valve plate 4 is cooled by the heat pipe 13 inside the valve plate 4. At this time, the liquid inside the heat pipe 13 inside the valve plate 4 vaporizes and moves to the upper and lower ends of the heat pipe 13, and the upper and lower ends of the heat pipe 13 are not in direct contact with the flue gas, so that the heat on the valve plate 4 is transferred to the upper and lower ends of the heat pipe 13. At this time, the heat on the heat pipe 13 is transferred to the valve body 1 in the form of thermal radiation.

[0029] See also Figure 1 and Figure 2A liquid separation box 5 is fixedly provided on the upper side of the outer side of the valve body 1, and the liquid separation box 5 is connected to the cooling pipe 12.

The mounting rods 17 are distributed equidistantly in a ring shape, and the other end of the mounting rods 17 is fixedly connected to the valve body 1, so that the fan blades 16 can be driven to rotate by the motor 15.

[0033] See also Figure 2 and Figure 4 The motor 15 is located inside the ventilation slot 14 and a fan blade 16 is fixedly provided on the outside of the output shaft to facilitate the formation of air flow through the fan blade 16 to blow toward the cooling pipe 12.

[0035] Working principle: When the cooling operation is carried out, the motor 15 is turned on, and the output shaft of the motor 15 drives the fan blade 16 to rotate. At this time, the air near the fan blade 16 flows and forms an airflow. The airflow generated by the fan blade 16 blows toward the cooling pipe 12. At this time, the coolant in the cooling pipe 12 transfers heat to the wall of the cooling pipe 12. The wall of the cooling pipe 12 is cooled by the airflow, and the coolant is cooled together with it. The cooled coolant flows back to the water tank through the liquid collecting box 7 and the liquid outlet pipe 8. When needed, When the valve plate 4 is closed, the hydraulic telescopic device 3 is opened at this time, so that the telescopic end of the hydraulic telescopic device 3 is extended and drives the valve plate 4 to move downward in the slide groove 9 until the valve plate 4 completely covers the through hole of the valve body 1. At this time, the sealing of the valve body 1 is completed. When the valve plate 4 needs to be opened, the hydraulic telescopic device 3 is opened at this time, so that the telescopic end of the hydraulic telescopic device 3 is contracted and drives the valve plate 4 to move upward in the slide groove 9 until the valve plate 4 exposes the through hole of the valve body 1.
