During the overall heat treatment process of the valve workpiece, the overall process flow is reasonable and efficient, and for the quenching process, the corresponding quenching treatment can be carried out according to the actual processing status and needs of the steel workpiece; through the coordinated use of the heat treatment purification recovery mechanism and the spray quenching mechanism, the slag and dirt adhered to the surface of the valve workpiece during quenching are removed, reducing unnecessary subsequent processes and improving the overall process economic benefits; and the heat in the hot waste gas and hot waste water generated during the quenching process can be recycled to a certain extent, improving energy utilization efficiency and meeting actual process requirements; In the above-mentioned search patent, its background technology mentions that the workpiece needs to be left to cool for a certain period of time after quenching, and during this process, impurity particles will adhere to the surface of the workpiece due to cooling, or impurities adhered to the workpiece when quenching in water, which need to be subsequently handled by staff, thereby increasing the processing process flow and having a negative impact on the overall process.

When the spline shaft connected to the special-shaped rod is located in the spline groove on the bottom pulley 2, it will drive the bottom pulley 2 to rotate synchronously, and transmit the belt to the top pulley 2 through the belt, so that the gear 2 connected to the pulley 2 meshes with the gear ring connected to the rolling drum, and the gear ring rotating with the rolling drum meshes with the gear 3 at the top, so that the gear 3 rotates the two meshing gears through the universal shaft. The bevel gear 2 of the bevel gear 2 drives the auger to rotate, and the rotating roller transports the heated iron sand to the output pipe through the spirally arranged stirring blades, and pours it into the conical cylinder at the output pipe. The worm driven by the motor meshes with the gear 1 at the rear end to rotate, and the multiple pulleys connected by the belt will rotate synchronously, so that the multiple gears 1 will synchronously mesh with the helical gear connected to the clamping piece to drive the clamping piece to drive the workpiece to rotate. After the iron sand falls into the conical cylinder, it will flow along the inner wall of the conical cylinder, and pass through the circular hole along the bottom hole of the conical cylinder at the left end to enter the output end on the left side of the branch pipe, enter the output end on the left side of the branch pipe, and flow into the inner The rotating auger transports the iron sand upward and back into the rolling drum, forming a circulating flow state.

After cooling, rotate the perforated circular plate again to make the circular hole on the circular plate coincide with the through hole on the right end.

Then the workpiece is taken out for subsequent production and processing.

[0016] The present invention provides a heat treatment device and method for high-pressure valve production, which has the following beneficial effects: 1. The present invention utilizes high-temperature iron sand to polish the surface of the workpiece to remove impurities remaining on the surface of the workpiece due to quenching.

[0024] Please see attached Figure 1 , Attachment Figure 4 and attached Figure 8The double-pass pipe is mainly composed of a branch pipe 26 located at the bottom side of the conical cylinder 2, and two output ends are separated by a partition. The top side of the branch pipe 26 is fixedly connected to the bottom side of the conical cylinder 2 through a shell 27. The inner wall of the shell 27 is rotatably connected with a perforated circular plate 28. Two through holes are provided on the bottom side of the conical cylinder 2. One of the output ends of the branch pipe 26 is connected to the input end of the inner cylinder 29 to recover the iron sand flowing into the branch pipe 26 and send the iron sand into the inner cylinder 29. The other output end of the branch pipe 26 is provided with a waste pipe for discharging waste water.

[0025] Specifically, a force-applying portion is provided on the perforated circular plate 28, and a slide groove is provided on the shell 27. When the force-applying portion is pulled to slide inside the slide groove, the perforated circular plate 28 will be driven to rotate, so that the position of the circular hole is displaced following the rotation of the perforated circular plate 28, so as to coincide with any one of the two through holes on the bottom side of the conical cylinder 2.

Because the cross-sectional shape of the special-shaped rod 18 is non-circular, the special-shaped rod 18 can slide inside the worm 15 and rotate with the rotation of the worm 15. When the special-shaped rod 18 is pushed to the left by the electric push rod 19, the spline shaft 20 connected to the special-shaped rod 18 will be inserted into the spline groove 21 on the bottom pulley 22, thereby driving the bottom pulley 22 to rotate synchronously and transmit it to the top pulley 22 through the belt, so that the gear 24 connected to the pulley 22 is meshed with the gear ring 25 connected to the rolling drum 4, and the gear ring 25 rotating with the rolling drum 4 is meshed with the gear 33 at the top, so that the gear 33 rotates the two meshing bevel gears 2 31 through the universal shaft 32, so that the bevel gear 2 31 drives the auger 30 to rotate. If the spline shaft 20 is pulled out, the transmission is stopped, so that the driven rolling drum 4 and the auger 30 stop.

[0027] Based on the above-mentioned high-pressure valve production heat treatment equipment, as another aspect of the present application, a high-pressure valve production heat treatment method includes the following steps: Step 1: First, heat the iron sand used as abrasive in the rolling drum 4 to 200-300° C.; Step 2: Place the quenched workpiece in the conical cylinder 2, align the opening of the workpiece with the outer wall of the clamping member 14, open the valve of the output pipe 8, and start the motor 16 to pour the heated iron sand into the conical cylinder 2 through the output pipe 8. The rotating workpiece contacts the flowing high-temperature iron sand to heat treat the surface of the workpiece; Step 3: Iron sand enters the inner cylinder 29 along the double-pass pipe, and re-enters the mixing cylinder through the conveyance of the inner cylinder 29 to form a cycle. The high-temperature iron sand heats the inner cylinder 29, and the residual heat is transferred to the clean water in the outer wall cavity of the inner cylinder 29 to heat the clean water. Step 4: After the workpiece surface is cleaned, close the valve of the output pipe 8, wait until the iron sand in the conical tube 2 flows out, turn on the water pump, and pour the heated clean water in the cavity into the conical tube 2 to cool the workpiece. After cooling, take out the workpiece.

[0028] This method uses high-temperature iron sand to grind the surface of the workpiece to remove the impurities left on the surface of the workpiece due to quenching. Through this heat treatment method, flame and special gas assistance are not required, thereby reducing the instability factors caused by special gases, thereby improving the safety and stability of the high-pressure valve production process. Among them, the iron sand and cooling water used as abrasives can be recycled and reused, and in the heat treatment process, the cooling water can be heated by the circulating iron sand, thereby further reducing the loss in the production process and reducing the processing and production expenses.
