Description

Technical Field

[0001] The invention relates to butterfly plate processing, in particular to a heat treatment device and a heat treatment process for preventing large butterfly plates from deforming. Background Art

[0002] A butterfly valve, also known as a flap valve, is a regulating valve with a simple structure. It can be used for the on-off control of low-pressure pipeline media. A butterfly valve refers to a valve whose closing member (valve disc or butterfly plate) is a disc that rotates around the valve axis to achieve opening and closing. During the use of a butterfly valve, a butterfly plate is required to control the fluid. Since the butterfly plate is subjected to a large pressure, high requirements are placed on the strength and precision of the butterfly plate. Therefore, the butterfly plate needs to be heat treated to increase its strength.

[0003] According to a Chinese patent with the announcement number "CN211005518U", a heat treatment device for butterfly valves is disclosed, including a barrel seat, a circular top seat is provided at the top of the barrel seat, a bottom plate is provided at the bottom of the barrel seat, a thermometer, a discharge port and a power supply seat are provided on the barrel seat, a sealing cover is provided on the discharge port, a heating tank is provided on the circular top seat, a leak hole is provided on the bottom surface of the tank body of the heating tank, and a closing cover is provided on the seat body of the circular top seat. This heat treatment device heats the butterfly valve through the heating tank, and the heating tank is heated in a targeted manner according to the size of the butterfly valve. Heat is not allowed to be lost, resulting in fast heating speed and high efficiency. Through the design of the exhaust port and the water injection port on the closing cover, after the butterfly valve is heated, water can be directly injected for cooling without taking out the butterfly valve, simplifying the connection process between heating and cooling. At the same time, the water vapor and excess cooling water generated during cooling will be uniformly collected and processed through the exhaust port and the discharge pipe, avoiding the problem of direct discharge to the outside and affecting the environment.

[0004] The above patent uses water injection for cooling during use, but the cooling is not uniform enough, which may easily lead to deformation of the butterfly plate.

[0045] Preferably, a quenching tank 6 is fixedly connected to one side of the base plate 1, and an atomizing mechanism 7 is arranged on the top of the quenching tank 6. The atomizing mechanism 7 includes an atomizing tank 71, an inner frame 72, a water tank 710, an atomizer 711, and a connecting pipe 712.

[0047] Preferably, the outer wall fixed sleeve of the atomizer tank 71 is provided with an annular groove 713, and the annular groove 713 is directly below the condensation plate 516, and the bottom of the annular groove 713 is connected to a drain pipe 714, and the drain pipe 714 is connected to the top of the water tank 710.

[0048] Working principle: The butterfly plate 9 is lifted by the hook 55, and the upper baffle 511 is driven down by starting the electric push rod 57. After the upper baffle 511 drops to the top of the block 56, the block 56 is driven down together, thereby driving the two connecting ropes 54 to be tightened. After the two hooks 55 are straightened, the electric push rod 57 drives the hemisphere 513 to rise. The rise of the hemisphere 513 squeezes the spring 510, thereby moving the L-shaped rod 59 outward and clamping the connecting rope 54, so that the hook 55 hoisting the butterfly plate 9 is more stable, and then the rotating column 3 is driven The butterfly plate 9 rotates to the top of the atomizing tank 71, and the rope 52 is unwound by starting the rope reel 51, thereby driving the butterfly plate 9 to descend into the inside of the atomizing tank 71. At this time, the support rod 515 is in conflict with the top of the atomizing tank 71, and the tank cover 514 covers the top of the atomizing tank 71. By starting the atomizer 711, the water in the water tank 710 is atomized and discharged into the inside of the atomizing tank 71 through the connecting pipe 712, and sprayed onto the butterfly plate 9 through the air outlet on the rotating drum 74, so as to gently cool the butterfly plate 9, reduce the internal stress of the butterfly plate 9, and make the butterfly plate 9 The temperature of the butterfly plate 9 is reduced to between 550°C and 650°C, thereby reducing the internal stress of the butterfly plate 9 and preventing the butterfly plate 9 from deforming. The motor 77 is started to drive the rotating rod 78 to rotate, thereby driving the gear 79 to rotate. The rotation of the gear 79 will drive the rotating drum 74 to rotate through the gear ring 76, so that the mist can be sprayed on the butterfly plate 9 more evenly, and the butterfly plate 9 is atomized and cooled. The steam generated by the cooling will be condensed through the tank cover 514 and the condensation plate 516 and then drip into the annular groove 713, and then discharged into the water tank 710 through the drain pipe 714 for circulation. When the quenching of the butterfly plate 9 is completed, the butterfly plate 9 is driven to rise by the rope reel 51, and the tank cover 514 is driven to rise by the fixed block 53, so that the top of the atomizer tank 71 is opened, and the butterfly plate 9 is taken out, and the lower baffle 512 is driven to rise by the electric push rod 57. When the lower baffle 512 rises to contact the bottom of the block 56, the hemispherical body 513 rises and separates from the L-shaped rod 59, so that the L-shaped rod 59 is driven to move inward under the action of the spring 510, so that the L-shaped rod 59 is separated from the connecting rope 54, so that the butterfly plate 9 is conveniently removed from the hook 55.

[0049] See also Figure 1-8 On the basis of the above embodiment, in another embodiment of the present invention, preferably, a circulation mechanism 8 is provided on the quenching tank 6, and the circulation mechanism 8 includes a circulating water pump 81, a first water pipe 82, and a second water pipe 83.

[0050] Preferably, a limiting rod 84 is fixedly connected to the bottom of the inner wall of the quenching tank 6 , a floating plate 85 is movably sleeved on the outer wall of the limiting rod 84 , and an observation window 86 is provided on the front of the quenching tank 6 .

[0051] Preferably, a water outlet pipe is connected to one side of the quenching tank 6 , and a control valve is provided on the water outlet pipe. There are two water outlet pipes, and the two water outlet pipes are arranged on the quenching tank 6 one above the other.

[0052] Working principle: water is injected into the quenching tank 6 to make the float plate 85 rise to the middle part of the quenching tank 6, and the position of the float plate 85 is observed through the observation window 86. After the water injection is completed, mineral oil is injected into the quenching tank 6, and the butterfly plate 9 that has been atomized and cooled continues to move downward. The butterfly plate 9 will first enter the mineral oil for gentle cooling again, and then continue to descend into the water to quickly cool the butterfly plate 9, thereby completing the quenching of the butterfly plate 9, and start the circulating water pump 81 to circulate the water through the first water pipe 82 and the second water pipe 83, so that the water flows, improves the cooling effect on the butterfly plate 9, and speeds up the cooling rate of the butterfly plate 9. When it is necessary to replace the water and mineral oil, first open the upper control valve, discharge the mineral oil through the upper outlet pipe, and then open the lower control valve to discharge the water.

[0053] A heat treatment process for preventing large butterfly plates from deforming comprises the following steps:

[0054] Step 1: Place the heated butterfly plate 9 on the hook 55, and rotate the butterfly plate 9 to the top of the quenching tank 6 through the rotating column 3;

[0055] Step 2: The butterfly plate 9 is driven to descend to the inside of the atomizing tank 71 by the rope reel 51, and the butterfly plate 9 is atomized and cooled by the atomizing mechanism 7, so that the butterfly plate 9 is gently cooled, and the temperature of the butterfly plate 9 is reduced to between 550° C. and 650° C., thereby reducing the internal stress of the butterfly plate 9;

[0056] Step three, the butterfly plate 9 is driven to continue to descend by the rope reel 51, so that the butterfly plate 9 is inside the quenching tank 6, and water and mineral oil are respectively injected into the quenching tank 6. The mineral oil is suspended on the water.
